The protection member 3 includes an insulative member, for example, resin. By covering the contacts 6a to 6h and the ground contacts 8a to 8f from the +Z direction side, the protection member 3 protects contact portions 5a to 5h (see
The through hole 16 is an elongated rectangular hole extending in the Y direction between the second openings 12a to 12d and the second openings 12e to 12h, and formed from the upper surface (+Z direction side) toward the lower surface (−Z direction side) of the protection member 3 (see
In addition, insertion holes 25d, 20e, 20f, 25e, 20g, 20h and 25f are formed in a row along the Y direction in a surface at a lower part on the right side (+X direction side) of the protection member 3.

The connector 10 is provided with the plurality of (six in this embodiment) ground contacts 8a to 8f. The ground contacts 8a to 8f include the ground contact portions 7a to 7f, respectively, to be connected to ground terminals (not shown) of the external device 100. The ground contacts 8a and 8b are disposed with the two contacts 6a and 6b interposed therebetween. The ground contacts 8b and 8c are disposed with the two contacts 6c and 6d interposed therebetween. The ground contacts 8d and 8e are disposed with the two contacts 6e and 6f interposed therebetween. The ground contacts 8e and 8f are disposed with the two contacts 6g and 6h interposed therebetween. The ground contacts 8a to 8f are formed wider in the X direction than the contacts 6a to 6h on the ZX plane in order to enhance the functions thereof as the grounds. When the external device 100 is pressed from the +Z direction side, the ground contact portions 7a to 7f come in contact with the ground terminals (not shown) of the external device 100.
As shown in
As shown in
The elastic member 24e includes a conductive member, and is formed integrally with the metal plate 32. That is, the elastic member 24e is connected to the ground via the metal plate 32. Furthermore, a lower part of the elastic member 24e is held on a held surface 2c of the base body 2, and an upper part of the elastic member 24e is constantly in contact with the lower surface 31 of the ground terminal 21e. That is, the elastic member 24e is connected to the ground via the ground terminal 21e. The elastic member 24e is formed separately from the contact 6e and presses the contact 6e in the +Z direction via the ground terminal 21e and the holding member 22e.
The metal plate 32 is disposed in the through hole 16 that is formed between the first contact group 9a and the second contact group 9b and at the central portion of the protection member 3. The −Z direction side of the metal plate 32 is fixed to the base body 2.
Before the protection member 3 moves in the −Z direction, the metal plate 32 does not protrude from the through hole 16 but is embedded in the through hole 16. When the protection member 3 moves in the −Z direction, the metal plate 32 protrudes from the through hole 16. When the external device 100 presses the protection member 3 and the protection member 3 moves in the −Z direction, the metal plate 32 is inserted into a metal plate insertion portion 104 of the external device 100 and connected to a grounding terminal 106 including a conductor. Before the protection member 3 moves in the −Z direction, the metal plate 32 may either be located on substantially the same plane as the upper surface of the protection member 3 or protrude from the through hole 16.

As shown in
The configurations of the ground contact 8a, the grounding coaxial cable 17a, and the elastic member 48a shown in
Next, displacement of the protection member 3 and the contact portion 5e in the process of pressing the external device 100 against the connector 10 according to the first embodiment will be described with reference to the drawings.
Before the external device 100 comes in contact with the protection member 3 and the contact portion 5e, as shown in
Next, when the external device 100 is pressed against the connector 10, the connection terminal 102 of the external device 100 comes in contact with and is pressed against the contact portion 5e, and a pressing force in the −Z direction is applied to the contact portion 5e. Then, the contact portion 5e moves in the −Z direction, and the elastic member 24e is compressed in the Z direction. In addition, along with the movement of the contact portion 5e, the protection member 3 moves in the −Z direction and the metal plate 32 protrudes from the through hole 16.
When the external device 100 is further pressed against the connector 10, as shown in
In the connector 10 according to the first embodiment, the contacts 6a to 6h and the elastic members 24a and 24e to 24h are formed separately, not integrally. Therefore, the design freedom of the connector can be enhanced. In other words, in a terminal in which the contact and the elastic member are integrated, the size and shape of the terminal, and hence the size and shape of the connector are heavily restricted, thus lowering the design freedom. According to the first embodiment, however, since the contact and the elastic member are formed separately, the design freedom concerning the size and shape of the contact increases, and thus the design freedom concerning the size and shape of the connector increases. An increase in the design freedom in turn makes it possible to make the connector compact.
Furthermore, since the design freedom concerning the size and shape of the contact increases, the structure of the contact and a transmission path of the connector can be simplified, and impedance matching for high-speed transmission can be easily performed. That is, it is possible to simplify the cross section of the connector that affects the impedance (the plane perpendicular to the transmission path of the connector) and to reduce the kinds of the cross sections of the connector. Therefore, the impedance can be easily adjusted using a coaxial cable matching the target impedance.
In the connector 10 according to the first embodiment, the contacts 6a to 6h and the elastic members 24a and 24e to 24h are formed separately, not integrally. Therefore, the structure can be simplified compared with that of a terminal in which a contact and an elastic member are integrated. In addition, since the shield member 28e of the coaxial cable 18e connected to the contact 6e and the elastic member 24e are connected to the ground, the ground can be reinforced and high-speed transmission characteristics can be improved. In addition, since the ground contacts are disposed with the contacts adjacent to each other interposed therebetween, the ground can be reinforced and the high-speed transmission characteristics can be improved. Furthermore, since the elastic members 24a, 24e to 24h, 48a and 48d to 48f, the ground contacts 8a to 8f, and the metal plate 32 are electrically connected, the ground can be further reinforced and the high-speed transmission characteristics can be improved.
In the connector 10 according to the first embodiment, since the protection member 3 protects the contact portions 5a to 5h, it is possible to provide a connector which is inexpensive and difficult to break down. For example, since the contact portions 5a to 5h are protected by the protection member 3, even when a finger, a pen tip or the like touches the connector 10 by mistake, deformation of the contacts 6a to 6h due to contact with a finger, a pen tip or the like can be prevented. Furthermore, the contact portion 5e and the like can be brought into contact with the connection terminal 102 and the like with a sufficient pressing force in the final coupled state.
The plurality of contacts 6a to 6h is provided in the above-described first embodiment, but at least one contact would suffice.
In the first embodiment, two contact groups, i.e., the first contact group 9a and the second contact group 9b are provided, but three or more contact groups may be provided.
In addition, although the connector 10 according to the first embodiment includes one metal plate 32, the connector 10 may include two metal plates. In this case, one metal plate is disposed on the protection member 3 and the other metal plate is disposed on the base body 2. A part of the one metal plate is disposed so as to overlap the other metal plate, and the one metal plate and the other metal plate are electrically connected to each other. Even when the protection member 3 moves in the Z direction, the one metal plate remains overlapping the other metal plate.
Next, a connector according to a second embodiment will be described with reference to the drawings. The connector according to the second embodiment includes a first connector mounted on, for example, a peripheral device such as a keyboard, and a second connector mounted on an external device such as a portable information terminal. The connector according to the second embodiment is a press-type connector that is electrically connected to the first connector by pressing a connection terminal of the second connector in a predetermined direction.
In the following description, the XYZ orthogonal coordinate system shown in
The base body 61 includes an insulative member, for example, resin. As shown in
The protection member 63 includes an insulative member, for example, resin. The protection member 63 protects first contact portions 64a (see
As shown in
Furthermore, as shown in
As shown in
As shown in
The first holding member 74 includes a pressing portion 74a that presses the protection member 63 upward (+Z direction). The pressing portion 74a presses the protection member 63 upward (+Z direction) by an elastic force of the first elastic member 75 before the second connector 79 is pressed (initial state). After the second connector 79 is pressed (final coupled state), the pressing portion 74a does not come in contact with or press the protection member 63. That is, in transition from the initial state to the final coupled state, the pressing portion 74a is initially brought into contact with and presses the protection member 63, and then gradually separates from the protection member 63 and ceases pressing the protection member 63.
The first elastic member 75 includes a conductive member, and as shown in
As shown in
As shown in
As shown in
The second holding member 76 includes a pressing portion 76a that presses the protection member 63 upward (+Z direction). The pressing portion 76a presses the protection member 63 upward (+Z direction) by an elastic force of the second elastic member 77 before the second connector 79 is pressed (initial state). After the second connector 79 is pressed (final coupled state), the pressing portion 76a does not come in contact with or press the protection member 63. That is, in transition from the initial state to the final coupled state, the pressing portion 76a is initially brought into contact with and presses the protection member 63, and then gradually separates from the protection member 63 and ceases pressing the protection member 63.
The second elastic member 77 includes a conductive member, and as shown in
As shown in
As shown in
That is, one of the ground terminals 73 and the other ground terminal 73 are electrically connected via the grounding connection member 78. As a result, the first shield member 67c connected to one of the ground terminals 73 and the first shield member 67c connected to the other ground terminal 73 are electrically connected to each other via the ground terminals 73 and the grounding connection member 78. In addition, the ground terminal 73 and the second contact 65 are electrically connected via the grounding connection member 78. Consequently, the first shield member 67c connected to the ground terminal 73, and the second core wire 68a and the second shield member 68c connected to the second contact 65 are electrically connected via the ground terminal 73, the second contact 65, and the grounding connection member 78. That is, the ground terminal 73 and the grounding connection member 78 function as connection members that electrically connect the first shield member 67c, the second core wire 68a, and the second shield member 68c to one another.
The first curved portion 78c and the second curved portion 78d of the grounding connection member 78 have flexibility (elasticity). Therefore, the grounding connection member 78 can follow the movement of the individual first holding members 74 (first contact portions 64a) in the Z direction and the movement of the individual second holding members 76 (second contact portions 65a) in the Z direction.
Next, the second connector 79 included in the connector according to the second embodiment will be described.
The first connection terminal 80 is electrically connected to the first contact 64 (see
The housing 84 includes an insulative member, for example, resin, and is covered with the shell 83. The shell 83 is formed of a conductive member, such as metal. As shown in
Next, displacement of the protection member 63 and the first contact portion 64a in the process of pressing the second connector 79 against the first connector 60 according to the second embodiment will be described with reference to the drawings. Since the displacement of the second contact portion 65a in the process of pressing the second connector 79 against the first connector 60 is substantially the same as the displacement of the first contact portion 64a, the description thereof will be omitted.
Before the second connector 79 comes in contact with the protection member 63, the first contact portion 64a, and the second contact portion 65a (initial state), as shown in
Next, when the second connector 79 is pressed against the first connector 60, the first connection terminal 80 of the second connector 79 comes in contact with and presses the first contact portion 64a, and thus a pressing force in the −Z direction is applied to the first contact portion 64a. The first contact portion 64a starts moving in the −Z direction, and along with the start of the movement of the first contact portion 64a, the protection member 63 also starts moving in the −Z direction. The first elastic member 75 starts being compressed in the Z direction, and the pressing portion 74a of the first holding member 74 presses the protection member 63 by the elastic force of the first elastic member 75.
When the second connector 79 is further pressed against the first connector 60, the first contact portion 64a further moves in the −Z direction, and the protection member 63 stops moving in the −Z direction. The first elastic member 75 is further compressed in the Z direction, and the pressing portion 74a of the first holding member 74 presses the protection member 63 by the elastic force of the first elastic member 75.
When the second connector 79 is further pressed against the first connector 60, the protection member 63 does not move, and only the first contact portion 64a moves in the −Z direction. The first elastic member 75 is further compressed in the Z direction, but the protection member 63 does not move. Therefore, the pressing of the protection member 63 by the pressing portion 74a of the first holding member 74 can be gradually released.
In the first connector 60 included in the connector according to the second embodiment, the first contact 64 and the first elastic member 75 (the second contact 65 and the second elastic member 77) are formed separately, not integrally. Therefore, the design freedom of the connector can be enhanced. In other words, in a terminal in which the contact and the elastic member are integrated, the size and shape of the terminal, and hence the size and shape of the connector are heavily restricted, thus lowering the design freedom. According to the second embodiment, however, since the contact and the elastic member are formed separately, the design freedom concerning the size and shape of the contact increases, and thus the design freedom concerning the size and shape of the connector increases. An increase in the design freedom in turn makes it possible to make the connector compact.
Furthermore, since the design freedom concerning the size and shape of the contact increases, the structure of the contact and a transmission path of the connector can be simplified, and impedance matching for high-speed transmission can be easily performed. That is, it is possible to simplify the cross section of the connector that affects the impedance (the plane perpendicular to the transmission path of the connector) and to reduce the kinds of the cross sections of the connector. Therefore, the impedance can be easily adjusted using a coaxial cable matching the target impedance.
In the first connector 60 included in the connector according to the second embodiment, the first contact 64 and the first elastic member 75 (the second contact 65 and the second elastic member 77) are formed separately, not integrally. Therefore, the structure can be simplified compared with that of a terminal in which a contact and an elastic member are integrated. The first shield member 67c of the first coaxial cable 67 connected to the first contact 64 and the second shield member 68c of the second coaxial cable 68 connected to the second contact 65 are connected to the ground via the ground terminal 73, the grounding connection member 78, and the second contact 65. Therefore, the ground can be reinforced and high-speed transmission characteristics can be improved. Since the adjacent first shield members 67c are electrically connected via the ground terminal 73 and the grounding connection member 78, the ground can be reinforced and high-speed transmission characteristics can be improved. Since the first shield member 67c, the second shield member 68c, the first elastic member 75, and the second elastic member 77 are electrically connected via the ground terminal 73 and the second contact 65, the ground can be reinforced and high-speed transmission characteristics can be improved. Since the second contacts 65 are disposed with the first contacts 64 adjacent to each other interposed therebetween, the ground can be reinforced and high-speed transmission characteristics can be improved.
In the first connector 60 included in the connector according to the second embodiment, the protection member 63 protects the first contact portion 64a and the second contact portion 65a. Therefore, it is possible to provide a connector that is inexpensive and difficult to break down. For example, since the first contact portion 64a and the second contact portion 65a are protected by the protection member 63, even when a finger, a pen tip or the like touches the first connector 60 by mistake, deformation of the first contact portion 64a and the second contact portion 65a due to contact with a finger, a pen tip or the like can be prevented. In addition, the first contact portion 64a and the second contact portion 65a can be brought into contact with the first connection terminal 80 and the second connection terminal 81 respectively with a sufficient pressing force in the final coupled state.
In the above-described second embodiment, there is provided the grounding connection member 78 that electrically connects the adjacent first shield members 67c and electrically connects the first shield member 67c and the second shield member 68c. However, it is also possible to provide a first connection member that electrically connects the adjacent first shield members 67c and a second connection member (separately from the first connection member) that electrically connects the first shield member 67c and the second shield member 68c.
Next, a connector according to a third embodiment will be described with reference to the drawings.
The first base body 15 includes an insulative member, for example, resin, and accommodates the protection member 37, the first contact 47, the second contact 49, the third contact 56, the fourth contact 57, the first coaxial cable 51, the second coaxial cable 55, and the metal plate 58. The rectangular first opening 15a is formed in the upper surface (+Z direction side) of the first base body 15. The second shell 35 and the protection member 37 protrude in the +Z direction through the first opening 15a. Five openings 15c are provided in a side surface 15b of the first base body 15 on the +X direction side, and five openings 15e are provided in a side surface 15d of the first base body 15 on the −X direction side. The openings 15c and 15e are rectangular openings having a longitudinal direction in the Z direction. Elastic bodies 35d (see
As shown in
As shown in
The protection member 37 includes an insulative member, for example, resin, and protects the first contact portion 47a of the first contact 47 (see
As shown in
As shown in
The first coaxial cable 51 includes the first core wire 51a, a first inner insulator 51b covering the first core wire 51a, a first shield member 51c including a conductor and covering the first core wire 51a via the first inner insulator 51b, and a first outer insulator 51d covering the first shield member 51c. The first inner insulator 51b electrically insulates the first core wire 51a from the first shield member 51c. The first shield member 51c functions as a grounding conductor (first grounding conductor) and is connected to the ground. The impedance between the first core wire 51a and the first shield member 51c is matched. The first coaxial cable 51 is fixed to the second base body 45 while being deflected within the second base body 45 by a length corresponding to the moving distance of a first holding member 53 to be described later in the Z direction and by a length corresponding to the moving distance of the protection member 37 in the Z direction.
Furthermore, as shown in
As shown in
The first holding member 53 includes a pressing portion that presses the second shell 35 upward (+Z direction). The pressing portion of the first holding member 53 presses the second shell 35 upward (+Z direction) by an elastic force of the first elastic member 54 before the second connector 13 is pressed (initial state). After the second connector 13 is pressed (final coupled state), the pressing portion does not come in contact with or press the second shell 35. That is, in transition from the initial state to the final coupled state, the pressing portion of the first holding member 53 is initially brought into contact with and presses the second shell 35, and then gradually separates from the second shell 35 and ceases pressing the second shell 35.
The first elastic member 54 includes a conductive member, and as shown in
As shown in
The second contact 49 includes an elastic body 49b on the +X direction side, and the elastic body 49b presses one of the comb teeth of the jumper plate 39 in the +X direction by an elastic force. In other words, the second contact 49 and the jumper plate 39 are electrically connected, and thus the ground terminal 52 and the second contact 49 are electrically connected by being pressed against the jumper plate 39. The second contact 49 and the jumper plate 39 are connected by the elastic force of the elastic body 49b. Therefore, even when each of the second holding members 59 (second contact portions 49a) individually moves in the Z direction, the second contact 49 and the jumper plate 39 can remain connected. Instead of the elastic body 49b, the comb teeth of the jumper plate 39 may be made elastic, in which case the second contact 49 and the jumper plate 39 are electrically connected by pressing the second contact 49 by the elastic force of the comb teeth.
Furthermore, as shown in
The second holding member 59 includes a pressing portion that presses the second shell 35 upward (+Z direction). The pressing portion of the second holding member 59 presses the second shell 35 upward (+Z direction) by an elastic force of the second elastic member 66 before the second connector 13 is pressed (initial state). After the second connector 13 is pressed (final coupled state), the pressing portion does not come in contact with or press the second shell 35. That is, in transition from the initial state to the final coupled state, the pressing portion of the second holding member 59 is initially brought into contact with and presses the second shell 35, and then gradually separates from the second shell 35 and ceases pressing the second shell 35.
The second elastic member 66 includes a conductive member. As shown in
The metal plate 58 is disposed in the vicinity of the first contact 47 and the second contact 49 and is fixed to the second base body 45. The metal plate 58 is formed integrally with the first elastic member 54 and the second elastic member 66, as described above. Therefore, the metal plate 58 is electrically connected to the first shield member 51c of the first coaxial cable 51 via the first elastic member 54 and the ground terminal 52. As shown in
As shown in
As shown in
Next, the second connector 13 included in the connector 1 according to the third embodiment will be described.
The housing 72 includes an insulative member, for example, resin, and is covered with the shell 69. The housing 72 includes twenty-two openings 72a for exposing the first connection surfaces 82a of the first connection terminals 82, twelve openings 72b for exposing the second connection surfaces 86a of the second connection terminals 86, four openings 72c for exposing the third connection surfaces 87a of the third connection terminals 87, and two openings 72d for exposing the grounding terminals 85a of the ground plate 85.
The third connection terminal 87 includes the third connection surface 87a at one end portion thereof, and is incorporated in the housing 72 while exposing the third connection surface 87a in the −Z direction through the opening 72c of the housing 72 and the opening 69a of the shell 69. When the second connector 13 is pressed against the first connector 11, the third connection surface 87a of the third connection terminal 87 is electrically connected to the third contact portion 56a (see
The ground plate 85 includes a conductive member, for example, metal, and is disposed in the vicinity of the plurality of first connection terminals 82. More specifically, the ground plate 85 is disposed on the +X direction side of the plurality of first connection terminals 82, and in a plane (YZ plane in the third embodiment) along an arrangement direction in which the plurality of first connection terminals 82 and the plurality of second connection terminals 86 are arranged in a row (Y direction). The ground plate 85 includes the twelve second connection terminals 86 formed by being bent in the −X direction from the end portion on the −Z direction side. In addition, the ground plate 85 includes the two grounding terminals 85a formed by being bent in the +X direction from the end portion on the −Z direction side, eleven bent portions 85b formed by being bent in the −X direction from the end portion on the +Z direction side, and twelve grounding terminals 85c formed by being bent in the −X direction from the end portion on the +Z direction side. The ground plate 85 is disposed in the vicinity of the plurality of first connection terminals 82, and is incorporated in the housing 72 while exposing the second connection surface 86a of the second connection terminal 86 in the −Z direction through the opening 72b of the housing 72 and the opening 69a of the shell 69, and exposing the grounding terminal 85a in the −Z direction through the opening 72d of the housing 72 and the opening 69a of the shell 69. The impedance between the first connection terminal 82 and the ground plate 85 is matched.
Next, displacement of the protection member 37 and the first contact portion 47a in the process of pressing the second connector 13 against the first connector 11 according to the third embodiment will be described. Since the displacement of the second contact portion 49a in the process of pressing the second connector 13 against the first connector 11 is substantially the same as the displacement of the first contact portion 47a, the description thereof will be omitted.
Before the second connector 13 comes in contact with the second shell 35, the protection member 37, the first contact portion 47a, and the second contact portion 49a (initial state), as shown in
Next, when the second connector 13 is pressed against the first connector 11, the first connection terminal 82 (first connection surface 82a) of the second connector 13 comes in contact with and presses the first contact portion 47a, and thus a pressing force in the −Z direction is applied to the first contact portion 47a. The first contact portion 47a starts moving in the −Z direction, and along with the start of the movement of the first contact portion 47a, the second shell 35 and the protection member 37 also start moving in the −Z direction.
When the second connector 13 is further pressed against the first connector 11, the first contact portion 47a further moves in the −Z direction, and the second shell 35 and the protection member 37 stop moving in the −Z direction. When the second connector 13 is further pressed against the first connector 11, the second shell 35 and the protection member 37 do not move, and only the first contact portion 47a moves in the −Z direction.
In the first connector 11 included in the connector 1 according to the third embodiment, the first contact 47 and the first elastic member 54 (the second contact 49 and the second elastic member 66) are formed separately, not integrally. Therefore, the design freedom of the connector can be enhanced. In other words, in a terminal in which the contact and the elastic member are integrated, the size and shape of the terminal, and hence the size and shape of the connector are heavily restricted, thus lowering the design freedom. According to the third embodiment, however, since the contact and the elastic member are formed separately, the structure can be simplified compared to that of a terminal in which the contact and the elastic member are integrated, the design freedom concerning the size and shape of the contact increases, and thus the design freedom concerning the size and shape of the connector increases. An increase in the design freedom in turn makes it possible to make the connector compact.
Furthermore, since the design freedom concerning the size and shape of the contact increases, the structure of the contact and a transmission path of the connector can be simplified, and impedance matching for high-speed transmission can be easily performed. That is, it is possible to simplify the cross section of the connector that affects the impedance (the plane perpendicular to the transmission path of the connector) and to reduce the kinds of the cross sections of the connector. Therefore, the impedance can be easily adjusted using a coaxial cable matching the target impedance.
In the first connector 11 included in the connector 1 according to the third embodiment, the protection member 37 protects the first contact portion 47a, the second contact portion 49a, and the third contact portion 56a. Therefore, it is possible to provide a connector that is inexpensive and difficult to break down. For example, since the first contact portion 47a, the second contact portion 49a, and the third contact portion 56a are protected by the protection member 37, even when a finger, a pen tip or the like touches the first connector 11 by mistake, deformation of the first contact portion 47a, the second contact portion 49a, and the third contact portion 56a due to contact with a finger, a pen tip or the like can be prevented. In addition, the first contact portion 47a, the second contact portion 49a, and the third contact portion 56a can be brought into contact with the first connection terminal 82, the second connection terminal 86, and the third connection terminal 87 respectively with a sufficient pressing force in the final coupled state.
In the first connector 11 included in the connector 1 according to the third embodiment, the first shield member 51c of the first coaxial cable 51, the jumper plate 39, and the first elastic member 54 are electrically connected via the ground terminal 52. The second core wire 55a of the second coaxial cable 55, the second shield member 55c of the second coaxial cable 55, and the jumper plate 39 are electrically connected via the second contact 49. The twenty-two ground terminals 52 and the twelve second contacts 49 are all electrically connected via the jumper plate 39. In addition, the twenty-two first elastic members 54 and the twelve second elastic members 66 are all electrically connected via the metal plate 58. Furthermore, the metal plate 58 is electrically connected to the second shell 35, and the second shell 35 is electrically connected to the first shell 33. In the final coupled state between the first connector 11 and the second connector 13, the metal plate 58 is electrically connected to the ground plate 85 of the second connector 13, and the second shell 35 is electrically connected to the shell 69 of the second connector 13. Therefore, it is possible to further reinforce the ground, and to improve the high-speed transmission characteristics. Since the second contacts 49 are disposed with the first contacts 47 adjacent to each other interposed therebetween, the ground can be reinforced and the high-speed transmission characteristics can be improved.
In the second connector 13 included in the connector 1 according to the third embodiment, the two adjacent first connection terminals 82 are disposed in the space formed by the ground plate 85, the bent portion 85b of the ground plate 85, and the second connection terminal 86. The impedance between the first connection terminal 82 and the ground plate 85 is matched, and the impedance between the first connection terminal 82 and the second connection terminal 86 is also matched. In addition, the ground plate 85 and the second connection terminal 86 are electrically connected. Furthermore, in the final coupled state between the first connector 11 and the second connector 13, the ground plate 85 is electrically connected to the metal plate 58 of the first connector 11, and the shell 69 is electrically connected to the second shell 35 of the first connector 11. Therefore, it is possible to further reinforce the ground, and to improve the high-speed transmission characteristics. Since the wide second connection terminals 86 are disposed with the first connection terminals 82 adjacent to each other interposed therebetween, the ground can be reinforced and the high-speed transmission characteristics can be improved.
In the second connector 13 according to the third embodiment described above, one ground plate 85 is provided, but two or more ground plates may be provided. When two ground plates (a first ground plate and a second ground plate) are provided, the first ground plate is disposed on the +X direction side of the plurality of first connection terminals 82, and the second ground plate on the −X direction side of the plurality of first connection terminals 82. That is, the plurality of first connection terminals 82 and the plurality of second connection terminals 86 are disposed (arranged in a row) between the first ground plate and the second ground plate. In this case, since the impedance among the first connection terminal 82, the first ground plate, and the second ground plate is matched, the ground can be further reinforced and the high-speed transmission characteristics can be improved.
It is also possible to employ a configuration in which the two adjacent first connection terminals 82 are surrounded by the plurality of ground plates and the plurality of second connection terminals 86. For example, the two adjacent first connection terminals 82 are surrounded using the above-described first and second ground plates and the second connection terminal 86 that is wider than the first connection terminal 82 on a plane intersecting the Y direction (plane along the ZX plane). In this case, the impedance between the first connection terminal 82 and the second connection terminal 86 is matched, and the impedance among the first connection terminal 82, the first ground plate, and the second ground plate is matched. Therefore, it is possible to further reinforce the ground, and to improve the high-speed transmission characteristics.
In the second connector 13 according to the third embodiment described above, the ground plate 85 and the second connection terminal 86 are integrally formed, but the ground plate 85 and the second connection terminal 86 may be formed separately instead.
Next, a connector according to a fourth embodiment will be described with reference to the drawings. The connector according to the fourth embodiment includes a first connector mounted on, for example, a peripheral device such as a keyboard, and a second connector mounted on an external device such as a portable information terminal. The connector according to the fourth embodiment is a press-type connector that is electrically connected to the first connector by pressing a connection terminal of the second connector in a predetermined direction. In the first connector and the second connector according to the fourth embodiment, the same components as those of the first connector 60 shown in
As shown in

As shown in
In addition, as in the first elastic member 94, a holding portion 97a (see
That is, the grounding connection member 98 is pressed against the ground terminal 92 by the elastic force of the first elastic member 94, and the grounding connection member 98 is pressed against the second contact 95 by the elastic force of the second elastic member 97, whereby the ground terminal 92 and the second contact 95 are electrically connected. In other words, the ground terminal 92 and the second contact 95, as well as the ground terminals 92, and the second contacts 95, can be electrically connected to each other via the grounding connection member 98 by the elastic force of the first elastic member 94 and the elastic force of the second elastic member 97 without soldering, for example. Therefore, a soldering step is not necessary in the step of assembling the first connector 89, and thus the assembling step can be facilitated. The grounding connection member 98 is not soldered to the ground terminal 92 or the second contact 95; therefore, even if the grounding connection member 98 does not have flexibility (elasticity), respective members move individually and the other members can follow the movement while being electrically connected. The ground terminal 92 and the grounding connection member 98 function as connection members that electrically connect the first shield member 67c, the second core wire 68a, and the second shield member 68c to one another.
In the first connector 89 according to the fourth embodiment, the first contact 91 and the first elastic member 94 (the second contact 95 and the second elastic member 97) are formed separately, not integrally. Therefore, the design freedom of the connector can be enhanced. In other words, in a terminal in which the contact and the elastic member are integrated, the size and shape of the terminal, and hence the size and shape of the connector are heavily restricted, thus lowering the design freedom. According to the fourth embodiment, however, since the contact and the elastic member are formed separately, the structure can be simplified compared to that of a terminal in which the contact and the elastic member are integrated, the design freedom concerning the size and shape of the contact increases, and thus the design freedom concerning the size and shape of the connector increases. An increase in the design freedom in turn makes it possible to make the connector compact.
Furthermore, since the design freedom concerning the size and shape of the contact increases, the structure of the contact and a transmission path of the connector can be simplified, and impedance matching for high-speed transmission can be easily performed. That is, it is possible to simplify the cross section of the connector that affects the impedance (the plane perpendicular to the transmission path of the connector) and to reduce the kinds of the cross sections of the connector. Therefore, the impedance can be easily adjusted using a coaxial cable matching the target impedance.
In the first connector 89 according to the fourth embodiment, the protection member 90 protects the first contact portion 91a and the second contact portion 95a. Therefore, it is possible to provide a connector that is inexpensive and difficult to break down. For example, since the first contact portion 91a and the second contact portion 95a are protected by the protection member 90, even when a finger, a pen tip or the like touches the first connector 89 by mistake, deformation of the first contact portion 91a and the second contact portion 95a due to contact with a finger, a pen tip or the like can be prevented. In addition, the first contact portion 91a and the second contact portion 95a can be brought into contact with the first connection terminal 80 and the second connection terminal 81 respectively with a sufficient pressing force in the final coupled state.
In the first connector 89 according to the fourth embodiment, the first shield member 67c of the first coaxial cable 67 and the first elastic member 94 are electrically connected via the ground terminal 92 and the grounding connection member 98. The second core wire 68a of the second coaxial cable 68, the second shield member 68c of the second coaxial cable 68, and the second elastic member 97 are electrically connected via the second contact 95 and the grounding connection member 98. The eight ground terminals 92 and the five second contacts 95 are all electrically connected via the grounding connection member 98. The eight first elastic members 94 and the five second elastic members 97 are also all electrically connected. Therefore, it is possible to further reinforce the ground, and to improve the high-speed transmission characteristics. Since the second contacts 95 are disposed with the first contacts 91 adjacent to each other interposed therebetween, the ground can be reinforced and the high-speed transmission characteristics can be improved.
The first connector 89 according to the fourth embodiment described above is provided with the grounding connection member 98 having the shape of a round bar. However, it is also possible to provide a grounding connection member having a shape other than the round bar, such as a beltlike planar grounding connection member, instead of the grounding connection member 98.
Next, a connector according to a fifth embodiment will be described with reference to the drawings. The connector according to the fifth embodiment includes a first connector mounted on, for example, a peripheral device such as a keyboard, and a second connector mounted on an external device such as a portable information terminal. The connector according to the fifth embodiment is a press-type connector that is electrically connected to the first connector by pressing a connection terminal of the second connector in a predetermined direction. In the first connector and the second connector according to the fifth embodiment, the same components as those of the first connector 89 shown in
A first connector 99 (see
As shown in
As shown in
In the first connector 99 according to the fifth embodiment, the first contact 91 and the first elastic member 94 (the second contact 95 and the second elastic member 97) are formed separately, not integrally. Therefore, the design freedom of the connector can be enhanced. In other words, in a terminal in which the contact and the elastic member are integrated, the size and shape of the terminal, and hence the size and shape of the connector are heavily restricted, thus lowering the design freedom. According to the fifth embodiment, however, since the contact and the elastic member are formed separately, the structure can be simplified compared to that of a terminal in which the contact and the elastic member are integrated, the design freedom concerning the size and shape of the contact increases, and thus the design freedom concerning the size and shape of the connector increases. An increase in the design freedom in turn makes it possible to make the connector compact.
Furthermore, since the design freedom concerning the size and shape of the contact increases, the structure of the contact and a transmission path of the connector can be simplified, and impedance matching for high-speed transmission can be easily performed. That is, it is possible to simplify the cross section of the connector that affects the impedance (the plane perpendicular to the transmission path of the connector) and to reduce the kinds of the cross sections of the connector. Therefore, the impedance can be easily adjusted using a coaxial cable matching the target impedance.
In the first connector 99 according to the fifth embodiment, the protection member 90 protects the first contact portion 91a and the second contact portion 95a. Therefore, it is possible to provide a connector that is inexpensive and difficult to break down. For example, since the first contact portion 91a and the second contact portion 95a are protected by the protection member 90, even when a finger, a pen tip or the like touches the first connector 99 by mistake, deformation of the first contact portion 91a and the second contact portion 95a due to contact with a finger, a pen tip or the like can be prevented. In addition, the first contact portion 91a and the second contact portion 95a can be brought into contact with the first connection terminal 80 and the second connection terminal 81 respectively with a sufficient pressing force in the final coupled state.
In the first connector 99 according to the fifth embodiment, the first shield member 67c of the first coaxial cable 67 and the first elastic member 94 are electrically connected via the ground terminal 92 and the grounding connection member 105. The second core wire 68a of the second coaxial cable 68, the second shield member 68c of the second coaxial cable 68, and the second elastic member 97 are electrically connected via the second contact 95 and the grounding connection member 105. The eight ground terminals 92 and the five second contacts 95 are all electrically connected via the grounding connection member 105. The eight first elastic members 94 and the five second elastic members 97 are also all electrically connected. Therefore, it is possible to further reinforce the ground, and to improve the high-speed transmission characteristics. Since the second contacts 95 are disposed with the first contacts 91 adjacent to each other interposed therebetween, the ground can be reinforced and the high-speed transmission characteristics can be improved.
Next, a connector according to a sixth embodiment will be described with reference to the drawings. The connector according to the sixth embodiment includes a first connector mounted on, for example, a peripheral device such as a keyboard, and a second connector mounted on an external device such as a portable information terminal. The connector according to the sixth embodiment is a press-type connector that is electrically connected to the first connector by pressing a connection terminal of the second connector in a predetermined direction. In the first connector and the second connector according to the sixth embodiment, the same components as those of the first connector 89 shown in
In the first connector according to the sixth embodiment, a first elastic member 101 and a second elastic member 107 each including a conductor are provided, in place of the first elastic member 94, the second elastic member 97, and the grounding connection member 98 shown in
The first bent portion 103 is electrically connected to one of adjacent ground terminals 92 and also to the other adjacent ground terminal 92. That is, the first bent portion 103 functions as a connection member that electrically connects one ground terminal 92 and the other ground terminal 92 (adjacent ground terminals 92), and the one ground terminal 92 and the other ground terminal 92 are electrically connected via the first bent portion 103. The second bent portion 108 is electrically connected to the adjacent ground terminal 92 and also to the adjacent second contact 95. That is, the second bent portion 108 functions as a connection member that electrically connects the adjacent ground terminal 92 and the adjacent second contact 95 (the ground terminal 92 and the second contact 95 adjacent to each other), and the ground terminal 92 and the second contact 95 are electrically connected via the second bent portion 108. Since the first bent portion 103 and the second bent portion 108 have flexibility, it is possible that respective members move individually and the other members follow the movement while being electrically connected.
In the first connector according to the sixth embodiment, the first contact 91 and the first elastic member 101 (the second contact 95 and the second elastic member 107) are formed separately, not integrally. Therefore, the design freedom of the connector can be enhanced. In other words, in a terminal in which the contact and the elastic member are integrated, the size and shape of the terminal, and hence the size and shape of the connector are heavily restricted, thus lowering the design freedom. According to the sixth embodiment, however, since the contact and the elastic member are formed separately, the structure can be simplified compared to that of a terminal in which the contact and the elastic member are integrated, the design freedom concerning the size and shape of the contact increases, and thus the design freedom concerning the size and shape of the connector increases. An increase in the design freedom in turn makes it possible to make the connector compact.
Furthermore, since the design freedom concerning the size and shape of the contact increases, the structure of the contact and a transmission path of the connector can be simplified, and impedance matching for high-speed transmission can be easily performed. That is, it is possible to simplify the cross section of the connector that affects the impedance (the plane perpendicular to the transmission path of the connector) and to reduce the kinds of the cross sections of the connector. Therefore, the impedance can be easily adjusted using a coaxial cable matching the target impedance.
In the first connector according to the sixth embodiment, the protection member 90 protects the first contact portion 91a and the second contact portion 95a. Therefore, it is possible to provide a connector that is inexpensive and difficult to break down. For example, since the first contact portion 91a and the second contact portion 95a are protected by the protection member 90, even when a finger, a pen tip or the like touches the first connector by mistake, deformation of the first contact portion 91a and the second contact portion 95a due to contact with a finger, a pen tip or the like can be prevented. In addition, the first contact portion 91a and the second contact portion 95a can be brought into contact with the first connection terminal 80 and the second connection terminal 81 respectively with a sufficient pressing force in the final coupled state.
In the first connector according to the sixth embodiment, the first shield member 67c of the first coaxial cable 67 and the first elastic member 101 are electrically connected via the ground terminal 92. The second core wire 68a of the second coaxial cable 68, the second shield member 68c of the second coaxial cable 68, and the second elastic member 107 are electrically connected via the second contact 95. The eight ground terminals 92 and the five second contacts 95 are all electrically connected via the first bent portions 103 and the second bent portions 108. The eight first elastic members 101 and the five second elastic members 107 are also all electrically connected. Therefore, it is possible to further reinforce the ground, and to improve the high-speed transmission characteristics. Since the second contacts 95 are disposed with the first contacts 91 adjacent to each other interposed therebetween, the ground can be reinforced and the high-speed transmission characteristics can be improved.
Next, a connector according to a seventh embodiment will be described with reference to the drawings. The connector according to the seventh embodiment includes a first connector mounted on, for example, a peripheral device such as a keyboard, and a second connector mounted on an external device such as a portable information terminal. The connector according to the seventh embodiment is a press-type connector that is electrically connected to the first connector by pressing a connection terminal of the second connector in a predetermined direction. In the first connector and the second connector according to the seventh embodiment, the same components as those of the first connector 89 shown in
A first connector 118 (see
As shown in
As shown in
The second holding member 121 holds the second contact 122 and the connection member 120 and is movable in the ±Z direction. That is, the second contact 122 moves in the ±Z direction along with the movement of the second holding member 121, and thus the position of the second contact portion 122a of the second contact 122 in the Z direction also changes. The second holding member 121 includes a square hole portion 121a for press-fitting a second press-fit portion 120g (see
A first shield member 67c of the first coaxial cable 67 is fixed to the first fixing portion 120a by soldering, for example. The first fixing portion 120a is formed by being bent in the shape of U so as to wrap the first shield member 67c. A second shield member 68c of the second coaxial cable 68 is fixed to the second fixing portion 120b by soldering, for example. The second fixing portion 120b is formed by being bent in the shape of U so as to wrap the second shield member 68c. A second core wire 68a of the second coaxial cable 68 is fixed to the ground portion 120c by soldering, for example. The ground portion 120c is formed to protrude in the +Z direction so as to be connected to the second core wire 68a. The ground portion 120c functions as a second fixing portion that fixes the second core wire 68a, which functions as a second grounding conductor.
The first flexible portion 120d is disposed between the adjacent first fixing portions 120a and has flexibility (elasticity). The second flexible portion 120e is disposed between the first fixing portion 120a and the second fixing portion 120b and has flexibility (elasticity). The first flexible portion 120d and the second flexible portion 120e are formed by being bent in the shape of U and then further bent in the shape of J. The first press-fit portion 120f is press-fitted into the first square hole portion 119a of the first holding member 119. The second press-fit portion 120g is press-fitted into the second square hole portion 121a of the second holding member 121.
Since the adjacent first fixing portions 120a are coupled by the first flexible portion 120d, the adjacent first shield members 67c are electrically connected. Since the first fixing portion 120a is coupled to the second fixing portion 120b and the ground portion 120c by the second flexible portion 120e, the first shield member 67c, the second core wire 68a, and the second shield member 68c are electrically connected. Since the first flexible portion 120d and the second flexible portion 120e have flexibility, it is possible that respective members move individually and the other members follow the movement while being electrically connected.
In the first connector 118 according to the seventh embodiment, the first contact 91 and the first elastic member 75 (the second contact 122 and the second elastic member 77) are formed separately, not integrally. Therefore, the design freedom of the connector can be enhanced. In other words, in a terminal in which the contact and the elastic member are integrated, the size and shape of the terminal, and hence the size and shape of the connector are heavily restricted, thus lowering the design freedom. According to the seventh embodiment, however, since the contact and the elastic member are formed separately, the structure can be simplified compared to that of a terminal in which the contact and the elastic member are integrated, the design freedom concerning the size and shape of the contact increases, and thus the design freedom concerning the size and shape of the connector increases. An increase in the design freedom in turn makes it possible to make the connector compact.
Furthermore, since the design freedom concerning the size and shape of the contact increases, the structure of the contact and a transmission path of the connector can be simplified, and impedance matching for high-speed transmission can be easily performed. That is, it is possible to simplify the cross section of the connector that affects the impedance (the plane perpendicular to the transmission path of the connector) and to reduce the kinds of the cross sections of the connector. Therefore, the impedance can be easily adjusted using a coaxial cable matching the target impedance.
In the first connector 118 according to the seventh embodiment, the protection member 90 protects the first contact portion 91a and the second contact portion 122a. Therefore, it is possible to provide a connector that is inexpensive and difficult to break down. For example, since the first contact portion 91a and the second contact portion 122a are protected by the protection member 90, even when a finger, a pen tip or the like touches the first connector 118 by mistake, deformation of the first contact portion 91a and the second contact portion 122a due to contact with a finger, a pen tip or the like can be prevented. In addition, the first contact portion 91a and the second contact portion 122a can be brought into contact with the first connection terminal 80 and the second connection terminal 81 respectively with a sufficient pressing force in the final coupled state.
In the first connector 118 according to the seventh embodiment, the eight first shield members 67c, the five second core wires 68a, and the five second shield members 68c are all electrically connected via the connection member 120. Therefore, it is possible to further reinforce the ground, and to improve the high-speed transmission characteristics. Since the second contacts 122 are disposed with the first contacts 91 adjacent to each other interposed therebetween, the ground can be reinforced and the high-speed transmission characteristics can be improved.
Next, a connector according to an eighth embodiment will be described with reference to the drawings. The connector according to the eighth embodiment includes a first connector mounted on, for example, a peripheral device such as a keyboard, and a second connector mounted on an external device such as a portable information terminal. The connector according to the eighth embodiment is a press-type connector that is electrically connected to the first connector by pressing a connection terminal of the second connector in a predetermined direction. In the first connector and the second connector according to the eighth embodiment, the same components as those of the first connector 89 shown in
