This application claims priority to and the benefit of Japanese Patent Application No. 2021-178123 filed on Oct. 29, 2021, the entire disclosure of which is incorporated herein by reference.
The present disclosure relates to a first connector and a connector module.
In recent years, the speed of signal transmission has been increasing in electronic devices, including information processing devices such as personal computers (PCs), industrial devices, and on-vehicle devices. Connectors for electrically connecting flexible flat cables (FFCs), flexible printed circuit boards (FPCs), and the like to circuit boards are also required to be designed for high-speed transmission.
For example, PTL 1 discloses an electrical connector that enables good electromagnetic shielding of signal transmission paths without additional operations.
A first connector according to an embodiment of the present disclosure is a first connector configured to be attached to a connection object that includes a plurality of contact lines exposed at a tip of the connection object and a ground portion covering part of the plurality of contact lines, the first connector comprising: a first insulator including a holding portion configured to hold the connection object in a state of accommodating the tip; and a first metal member attached to the first insulator, wherein the first metal member includes: a first base portion that is plate-shaped; a first contact portion configured to extend from the first base portion toward the tip and contact the plurality of contact lines; and a second contact portion configured to be located more on a side opposite to the tip than the first contact portion and contact the ground portion.
A connector module according to an embodiment of the present disclosure is a connector module comprising: the foregoing first connector; and a second connector configured to be fitted to the first connector, wherein the second connector includes: a second insulator configured to be fitted to the first insulator; and a first contact attached to the second insulator, and the first contact includes a third contact portion configured to contact the first metal member.
A connector module according to an embodiment of the present disclosure is a connector module comprising: the foregoing first connector; and a second connector configured to be fitted to the first connector, wherein the second connector includes: a second insulator configured to be fitted to the first insulator; and a first contact attached to the second insulator, and the first contact includes a third contact portion configured to contact the plurality of contact lines which the first contact portion is configured to contact.
In the accompanying drawings:
For the electrical connector described in PTL 1, improvement in transmission characteristics in signal transmission, including suppression of crosstalk, under high-speed transmission standards such as Universal Serial Bus (USB) 4.0 is not fully considered.
With a first connector and a connector module according to an embodiment of the present disclosure, it is possible to obtain good transmission characteristics in signal transmission.
An embodiment of the present disclosure will be described in detail below, with reference to the attached drawings. The directions such as front, back, right, left, up (top), and down (bottom) in the following description are based on the directions of the arrows in the drawings. The directions of the arrows are consistent throughout the drawings. In some drawings, the below-described circuit board CB is omitted for the sake of simplicity.
The connector module 1 includes the first connector 10 and the second connector 50 connectable to each other.
The second connector 50 according to the embodiment is mounted on the circuit board CB. The circuit board CB may be a rigid board, or any circuit board other than a rigid board. The second connector 50 electrically connects the connection object 40 inserted in the second connector 50 together with the first connector 10 and the circuit board CB. The connection object 40 can be inserted into and removed from the second connector 50 via the first connector 10. The second connector 50 is connected to the connection object 40 in a state in which the connection object 40 is inserted.
The second connector 50 includes a second insulator 60, one or more first contacts 70a, one or more second contacts 70b, and a second metal member 80. The first contacts 70a, the second contacts 70b, and the second metal member 80 are attached to the second insulator 60.
The first connector 10 holds the connection object 40. For example, the first connector 10 receives the connection object 40 inserted backward from the front and supports the right and left ends of the connection object 40 to hold the whole connection object 40.
The connection object 40 held by the first connector 10 is, for example, an FFC. The connection object 40 is, however, not limited to this, and may be any cable that is electrically connected to the circuit board CB via the first connector 10 and the second connector 50. For example, the connection object 40 may be an FPC. The connection object 40 is not limited to cables as described above and may include any object. For example, the connection object 40 may include a rigid board or any other circuit board.
The first connector 10 can be connected to the second connector 50 in a state of holding the connection object 40. The first connector 10 includes a first insulator 20 that is fitted to the second insulator 60 in a connected state in which the first connector 10 and the second connector 50 are connected to each other. The first connector 10 includes a first metal member 30 attached to the first insulator 20.
The connection object 40 contacts the second contacts 70b in a fitted state in which the first insulator 20 and the second insulator 60 are fitted to each other. The first metal member 30 contacts the first contacts 70a in a fitted state in which the first insulator 20 and the second insulator 60 are fitted to each other.
In the following description, for example, it is assumed that the second connector 50 according to the embodiment is a receptacle connector, that the first connector 10 is a plug connector, that the second connector 50 in which the first contacts 70a and the second contacts 70b elastically deform in a fitted state in which the first insulator 20 and the second insulator 60 are fitted to each other is a receptacle connector, and that the first connector 10 holding the connection object 40 in the fitted state is a plug connector. The types of the first connector 10 and the second connector 50 are not limited to such. For example, the second connector 50 may serve as a plug connector and the first connector 10 as a receptacle connector.
In the following description, it is assumed that the connection object 40 is inserted into the second connector 50 in a direction parallel to the circuit board CB on which the second connector 50 is mounted. For example, the connection object 40 is inserted into the second connector 50 in the front-back direction. The insertion direction is not limited to such. The connection object 40 may be inserted into the second connector 50 in a direction orthogonal to the circuit board CB on which the second connector 50 is mounted. The connection object 40 may be inserted into the second connector 50 in the up-down direction.
Herein, the term “extending direction of the plurality of contact lines” means the front-back direction as an example. The term “insertion/removal direction” means the front-back direction as an example. The term “direction orthogonal to the extending direction of the plurality of contact lines” means the up-down direction as an example. The term “tip of the connection object” means the back tip of the connection object as an example. The term “removal side” means the front side as an example. The term “insertion side” means the back side as an example.
The connection object 40 has a stack structure formed by bonding a plurality of thin film materials to each other. The connection object 40 includes a reinforcement portion 41 constituting a tip part in the extending direction of the connection object 40, i.e. the insertion/removal direction in which the connection object 40 is inserted and removed, and harder than other parts. The connection object 40 includes a plurality of contact lines 42 linearly extending in the insertion/removal direction to the tip of the reinforcement portion 41. Each contact line 42 is exposed downward at the tip of the connection object 40.
The connection object 40 includes a first ground portion 43 that covers part of the plurality of contact lines 42 with the lower outermost layer on the removal side of the connection object 40. The first ground portion 43 extends in a flat plate shape from the front toward the back and is bent obliquely upward at its tip. The connection object 40 includes a second ground portion 44 that covers substantially the whole contact lines 42 with the upper outermost layer. The second ground portion 44 extends in a flat plate shape from the front toward the back and is bent obliquely upward at the front edge of the reinforcement portion 41 and stacked on the reinforcement portion 41 at its tip part.
The connection object 40 includes a locked portion 45 formed by notching, inward in the right-left direction, the center of each edge extending in the front-back direction of the tip part of the connection object 40 including the reinforcement portion 41. The locked portion 45 is formed on both of the right and left sides in the tip part of the connection object 40 including the reinforcement portion 41.
The first insulator 20 is a symmetrical box-shaped member obtained by injection molding an insulating and heat-resistant synthetic resin material. The first insulator 20 includes an outer peripheral wall 21 including four outer walls on the top, bottom, right, and left sides and shaped rectangular as a whole. The outer peripheral wall 21 includes a ceiling wall 21a, a bottom wall 21b, and a pair of side walls 21c. As illustrated in

The first metal member 30 is obtained by forming a thin plate of any metal material into the shape illustrated in
The first metal member 30 includes a first base portion 31 that is plate-shaped in the front, back, right, and left directions. The first base portion 31 includes a first part 31a that is formed as a flat plate extending in the front, back, right, and left directions, and a second part 31b that bends obliquely upward from the back edge of the first part 31a and then extends horizontally.
The first metal member 30 includes one or more first contact portions 32 each of which extends backward from the back edge of the first base portion 31, for example, the second part 31b. The first contact portion 32 bends obliquely upward from the back edge of the second part 31b and then extends horizontally at its back end. The first contact portion 32 is formed so as to be wide in the right-left direction from the part connected to the second part 31b to the center of the part extending obliquely upward and be tapered therefrom toward the tip. The first contact portion 32 is notched in the thickness direction at the center of the part wide in the right-left direction. The first contact portion 32 is elastically deformable in the up-down direction.
The first metal member 30 includes one or more second contact portions 33 each of which is located forward from the first contact portion 32 and extends backward from the back of the first base portion 31, for example, the first part 31a. As illustrated in
A total of four pairs of the first contact portion 32 and the second contact portion 33 are formed in the first metal member 30, two pairs on each of the right and left sides. The pairs of the first contact portion 32 and the second contact portion 33 are arranged apart from each other in the right-left direction. The first contact portion 32 and the second contact portion 33 are linearly arranged in the front-back direction.
The first metal member 30 includes a plurality of tip-up portions 34 arranged at regular intervals in the right-left direction in the central part of the first part 31a of the first base portion 31 in the front-back direction. Each tip-up portion 34 linearly extends obliquely upward from the first part 31a and bends upward at its back end. The tip-up portion 34 is tapered so that the width in the right-left direction will continuously decrease from the part connected to the first part 31a to the back end. The whole tip-up portion 34 is located above the notch formed in the first part 31a in the thickness direction. The tip-up portion 34 is elastically deformable in the up-down direction. The tip-up portion 34 is not located on the same straight line as the pair of the first contact portion 32 and the second contact portion 33 but located at a position different from the pair of the first contact portion 32 and the second contact portion 33 in the right-left direction.
The first metal member 30 includes locking parts 35 formed at both of the right and left edges of the first part 31a of the first base portion 31.
As illustrated in
The functions of the first connector 10 when the first metal member 30 is attached to the first insulator 20 will be mainly described below.
When the first metal member 30 is attached to the first insulator 20, the locking parts 35 are fixed in the inner surfaces of the side walls 21c on the right and left. The back corners of the right and left edges of the first part 31a of the first base portion 31 face the forward-facing inner surfaces of the side walls 21c.

The functions of the first connector 10 when the connection object 40 is inserted in the first insulator 20 and the first connector 10 is attached to the connection object 40 will be mainly described below.
As illustrated in
As illustrated in
The first contact portion 32 and the second contact portion 33 are located on the same side of the connection object 40 in the direction orthogonal to the extending direction of the plurality of contact lines 42. More specifically, the first contact portion 32 and the second contact portion 33 are located on the same side of the connection object 40 in the up-down direction which is orthogonal to both the extending direction of the plurality of contact lines 42 and the arrangement direction of the first contacts 70a and the second contacts 70b of the second connector 50. The first contact portion 32 contacts the part of each of the plurality of contact lines 42 adjacent to the boundary R between each contact line 42 and the first ground portion 43. The second contact portion 33 contacts the part of the first ground portion 43 adjacent to the boundary R. The first contact portion 32 and the second contact portion 33 are arranged linearly in the extending direction of the plurality of contact lines 42.
As illustrated in
As illustrated in
The tip-up portion 34 is located on the same side of the connection object 40 as the first contact portion 32 and the second contact portion 33 in the direction orthogonal to the extending direction of the plurality of contact lines 42. The tip-up portion 34 is not located on the same straight line in the extending direction of the plurality of contact lines 42 as the first contact portion 32 and the second contact portion 33 but located at a position different from the first contact portion 32 and the second contact portion 33 in the right-left direction.
The second part 31b of the first base portion 31 extends backward from the first part 31a and contacts the first ground portion 43. The second part 31b is located more on the side opposite to the tip of the connection object 40 than the first contact portion 32 and the second contact portion 33. The second part 31b is located on the same side of the connection object 40 as the first contact portion 32 and the second contact portion 33 in the direction orthogonal to the extending direction of the plurality of contact lines 42.
The second connector 50 is assembled by the following method as an example. The first contacts 70a and the second contacts 70b are press-fitted into the second insulator 60 from behind the second insulator 60. The second metal member 80 is press-fitted into the second insulator 60 so as to cover the whole second insulator 60 from above. With reference to

The second insulator 60 includes second hole portions 64b formed at both of the right and left ends of the ceiling wall 61a and passing through the ceiling wall 61a from the upper surface of the ceiling wall 61a to the insertion portion 63. A pair of second hole portions 64b are arranged on each of the right and left outer sides of the entire four first hole portions 64a. Each second hole portion 64b extends linearly over substantially the whole ceiling wall 61a in the front-back direction.
The second insulator 60 includes a plurality of third hole portions 64c arranged apart from each other in the right-left direction, at the front edge of the ceiling wall 61a. As illustrated in

Each first contact 70a is obtained by forming a thin plate of a copper alloy or a corson copper alloy having spring elasticity, such as phosphor bronze, beryllium copper, or titanium copper, into the shape illustrated in
Each first contact 70a includes a locking part 71a that is rectangular in shape and has a projection at its upper edge. The first contact 70a includes a mounted portion 72a extending backward in an L shape from the lower end of the locking part 71a. The first contact 70a includes a third contact portion 73a extending forward while being bent from the front end of the locking part 71a. The first contact 70a includes a sixth contact portion 74a located at the back edge of the locking part 71a.
Each second contact 70b is obtained by forming a thin plate of a copper alloy or a corson copper alloy having spring elasticity, such as phosphor bronze, beryllium copper, or titanium copper, into the shape illustrated in
Each second contact 70b includes a locking part 71b that is rectangular in shape and has a projection at its upper edge. The second contact 70b includes a mounted portion 72b extending backward in an L shape from the lower end of the locking part 71b. The second contact 70b includes a fourth contact portion 73b extending forward while being bent from the front end of the locking part 71b.
The second metal member 80 is obtained by forming a thin plate of any metal material into the shape illustrated in
The second metal member 80 includes a second base portion 81 that forms the upper part of the second metal member 80 and is plate-shaped. As illustrated in

As illustrated in
The second metal member 80 includes a first locking part 85a extending downward in a U shape from each of the right and left ends of the back edge of the second base portion 81. The first locking part 85a is fixed in the back wall 62 of the second insulator 60 illustrated in
As illustrated in
With reference to
As illustrated in
As illustrated in
The fifth contact portion 83 of the second metal member 80 contacts the first contact 70a and extends from part of the second metal member 80 including the second base portion 81. As also illustrated in
As described above, the first contact 70a contacts both the first metal member 30 of the first connector 10 and the second metal member 80 of the second connector 50. The first contact 70a is used for ground as an example.
As illustrated in
Thus, the second contact 70b directly contacts the plurality of contact lines 42 of the connection object 40. The second contact 70b is used for signals as an example.
The seventh contact portion 87 of the second metal member 80 is located in the first hole portion 64a of the second insulator 60. The seventh contact portion 87 of the second metal member 80 contacts the connection object 40 and extends obliquely downward from the second base portion 81 while being bent in a U shape. More specifically, the seventh contact portion 87 contacts the second ground portion 44 of the connection object 40. Here, the seventh contact portion 87 elastically deforms upward.
The effects of the first connector 10 will be mainly described below. The same description applies to the connector module 1 including the first connector 10.
With the first connector 10 according to the embodiment described above, it is possible to obtain good transmission characteristics in signal transmission. In the first connector 10, the first contact portion 32 of the first metal member 30 contacts the plurality of contact lines 42 of the connection object 40, and the second contact portion 33 of the first metal member 30 contacts the first ground portion 43 of the connection object 40. Therefore, part of the plurality of contact lines 42 of the connection object 40 can be electrically connected to the first ground portion 43 via the first metal member 30. The contact line 42, the first metal member 30, and the first ground portion 43 thus stably function as one ground. As a result of part of the plurality of contact lines 42 stably functioning as ground, crosstalk between the other contact lines 42 through which electrical signals are transmitted is suppressed.
The first contact portion 32 and the second contact portion 33 are located on the same side of the connection object 40 in the direction orthogonal to the extending direction of the plurality of contact lines 42. Thus, all contact structures between the first metal member 30 and the connection object 40 can be located on the same side. For example, by arranging such contact structures only on the lower side of the connection object 40 and not on the upper side of the connection object 40, the height of the first connector 10 can be reduced as compared with the case where the contact structures are located on both sides. As a result, the height of the whole connector module 1 can be reduced. In addition, since the first contact portion 32 and the second contact portion 33 contact the connection object 40 on the same side of the connection object 40, crosstalk between the plurality of contact lines 42 through which electrical signals are transmitted is suppressed as compared with the case where the contact structures are located on both of the upper and lower sides to contact the connection object 40.
The first contact portion 32 contacts the part of each of the plurality of contact lines 42 adjacent to the boundary R, and the second contact portion 33 contacts the part of the first ground portion 43 adjacent to the boundary R. This can shorten the distance between the first contact portion 32 and the second contact portion 33. The contact part between the first metal member 30 and the contact line 42 and the contact part between the first metal member 30 and the first ground portion 43 are close to each other. The contact line 42, the first metal member 30, and the first ground portion 43 thus function as one ground more stably. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.
The first contact portion 32 and the second contact portion 33 are linearly arranged in the extending direction of the plurality of contact lines 42. This can shorten the distance between the first contact portion 32 and the second contact portion 33 as compared with the case where the first contact portion 32 and the second contact portion 33 are not located on the same straight line. The contact part between the first metal member 30 and the contact line 42 and the contact part between the first metal member 30 and the first ground portion 43 are close to each other. The contact line 42, the first metal member 30, and the first ground portion 43 thus function as one ground more stably. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.
The first contact portion 32 and the second contact portion 33 are elastically deformable and contact the connection object 40 in an elastically deformed state. This improves the contact reliability. For example, even when the connection object 40 vibrates, the first contact portion 32 and the second contact portion 33 deform elastically, as a result of which the contact with the connection object 40 is maintained more reliably. In addition, the tolerance of the thickness of the connection object 40 in the up-down direction can be absorbed when the connection object 40 is inserted into the first connector 10. Thus, the workability when inserting and holding the connection object 40 in the first connector 10 is improved. Moreover, the first connector 10 can improve the contact reliability with the connection object 40 as compared with the case where the first contact portion 32 and the second contact portion 33 are not elastically deformed. This improves the assemblability between the first connector 10 and the connection object 40. Consequently, the productivity when producing electronic devices by electrically connecting the connection object 40 and the circuit board CB via the connector module 1 is improved.
One first contact portion 32 contacts a plurality of contact lines 42. This further ensures the contact between the first metal member 30 and the plurality of contact lines 42 of the connection object 40 and improves the robustness when the first metal member 30 and the plurality of contact lines 42 contact each other. The contact line 42, the first metal member 30, and the first ground portion 43 thus function as one ground more stably. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed.
The first metal member 30 contacts the plurality of contact lines 42 and the first ground portion 43, so that the shielding effect of the first ground portion 43 of the connection object 40 can be extended to the plurality of contact lines 42. The contact line 42, the first metal member 30, and the first ground portion 43 function as one shield.
The first contact 70a of the second connector 50 includes the third contact portion 73a that contacts the first metal member 30, so that the number of contacts as ground increases. The first contact 70a of the second connector 50 can also be electrically connected to the first ground portion 43 via the first metal member 30. The first contact 70a, the contact line 42, the first metal member 30, and the first ground portion 43 thus stably function as one ground. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.
The first contact 70a indirectly contacts the plurality of contact lines 42 via the third contact portion 73a and the first metal member 30. This makes it possible to easily change the spacing between the first contacts 70a in the right-left direction.
The third contact portion 73a is located on the same side of the connection object 40 as the first contact portion 32 in the direction orthogonal to the extending direction of the plurality of contact lines 42. Thus, all contact structures between the first contact 70a and the first metal member 30 and contact structures between the first metal member 30 and the connection object 40 can be located on the same side. For example, by arranging such contact structures only on the lower side of the connection object 40 and not on the upper side of the connection object 40, the height of the whole connector module 1 can be reduced as compared with the case where the contact structures are located on both sides.
The second contact 70b includes the fourth contact portion 73b that contacts the plurality of contact lines 42, and the fourth contact portion 73b is located on the same side of the connection object 40 as the first contact portion 32 in the direction orthogonal to the extending direction of the plurality of contact lines 42. Thus, all contact structures between the second contact 70b and the connection object 40 and contact structures between the first metal member 30 and the connection object 40 can be located on the same side. For example, by arranging such contact structures only on the lower side of the connection object 40 and not on the upper side of the connection object 40, the height of the whole connector module 1 can be reduced as compared with the case where the contact structures are located on both sides.
The fifth contact portion 83 of the second metal member 80 contacts the first contact 70a and extends from part of the second metal member 80 including the second base portion 81, so that the number of contacts as ground increases. The second metal member 80 can also be electrically connected to the first ground portion 43 via the first contact 70a and the first metal member 30. The second metal member 80, the first contact 70a, the contact line 42, the first metal member 30, and the first ground portion 43 thus stably function as one ground. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.
The second metal member 80 is press-fitted into the second insulator 60 so as to cover the whole second insulator 60 from above, so that the outflow and inflow of noise for electrical signals are suppressed. For example, electromagnetic noise generated from an electrical signal transmitted by the second contact 70b is prevented from flowing out of the second connector 50. For example, electromagnetic noise generated from other electronic components arranged on the circuit board CB is prevented from flowing into the second connector 50.
The fifth contact portion 83 extends from the third base portion 82 that extends from the second base portion 81 while being bent to the first contact 70a side and lies along the end surface of the second insulator 60 in the extending direction of the plurality of contact lines 42. This improves the robustness as the strength of the contact portion, as compared with the case where the fifth contact portion 83 extends directly from the second base portion 81. Therefore, the second metal member 80 and the first contact 70a can stably contact each other via the fifth contact portion 83. The second metal member 80, the first contact 70a, the contact line 42, the first metal member 30, and the first ground portion 43 thus function as one ground more stably. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.
The third contact portion 73a and the sixth contact portion 74a are located at opposite ends of the first contact 70a in the extending direction of the plurality of contact lines 42. This enables stable contact of the first contacts 70a with both the first metal member 30 of the first connector 10 and the second metal member 80 of the second connector 50. Therefore, the first metal member 30 and the second metal member 80 can be electrically connected to each other stably via the first contact 70a. The second metal member 80, the first contact 70a, the contact line 42, the first metal member 30, and the first ground portion 43 thus function as one ground more stably. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.
The seventh contact portion 87 of the second metal member 80 extends from the second base portion 81 and contacts the connection object 40, so that the number of contacts as ground increases. The second metal member 80 is electrically connected to the first ground portion 43 of the connection object 40 via the fifth contact portion 83 and also electrically connected to the second ground portion 44 of the connection object 40 via the seventh contact portion 87. Therefore, the second ground portion 44 can also be electrically connected to the first ground portion 43 via the second metal member 80, the first contact 70a, and the first metal member 30. The second ground portion 44, the second metal member 80, the first contact 70a, the contact line 42, the first metal member 30, and the first ground portion 43 thus stably function as one ground. Consequently, crosstalk between the other contact lines 42 through which electrical signals are transmitted is further suppressed, and the transmission characteristics in signal transmission are further improved.
The seventh contact portion 87 is elastically deformable. This improves the contact reliability. For example, even when the connection object 40 vibrates, the seventh contact portion 87 deforms elastically, as a result of which the contact with the connection object 40 is maintained more reliably. In addition, the tolerance of the thickness of the connection object 40 in the up-down direction can be absorbed when the connection object 40 is inserted into the second connector 50. Thus, the workability when inserting the connection object 40 held by the first connector 10 into the second connector 50 is improved. Moreover, the second connector 50 can hold the connection object 40 more stably than in the case where the seventh contact portion 87 is not elastically deformed. The second connector 50 can also improve the contact reliability with the connection object 40. This improves the assemblability between the second connector 50 and the connection object 40. Consequently, the productivity when producing electronic devices by electrically connecting the connection object 40 and the circuit board CB via the connector module 1 is improved.

Although the foregoing embodiment describes the case where both the first contact portion 32 and the second contact portion 33 are elastically deformable and contact the connection object 40 in an elastically deformed state, the present disclosure is not limited to such. Only one of the first contact portion 32 and the second contact portion 33 may be elastically deformable, or neither of them may be elastically deformable.
Although the foregoing embodiment describes the case where one first contact portion 32 contacts two contact lines 42 adjacent to each other, the present disclosure is not limited to such. One first contact portion 32 may contact three or more contact lines 42, or contact only one contact line 42.
Although the foregoing embodiment describes the case where a total of four pairs of the first contact portion 32 and the second contact portion 33 are formed in the first metal member 30, two pairs on each of the right and left sides, as illustrated in
Although the foregoing embodiment describes the case where the first contact 70a includes the third contact portion 73a that contacts the first metal member 30, the present disclosure is not limited to such. The first contact 70a may contact, for example, the plurality of contact lines 42 of the connection object 40, instead of contacting the first metal member 30. Here, the first contact 70a may be used not for ground but for signals.
Although the foregoing embodiment describes the case where the third contact portion 73a is located on the same side of the connection object 40 as the first contact portion 32 in the direction orthogonal to the extending direction of the plurality of contact lines 42, the present disclosure is not limited to such. The first contact portion 32 and the third contact portion 73a may be located on different sides of the connection object 40.
Although the foregoing embodiment describes the case where the fourth contact portion 73b is located on the same side of the connection object 40 as the first contact portion 32 in the direction orthogonal to the extending direction of the plurality of contact lines 42, the present disclosure is not limited to such. The first contact portion 32 and the fourth contact portion 73b may be located on different sides of the connection object 40.
Although the foregoing embodiment describes the case where the second metal member 80 includes the fifth contact portion 83 that contacts the first contact 70a and extends from part of the second metal member 80 including the second base portion 81, the present disclosure is not limited to such. The second metal member 80 may not contact the first contact 70a. Although the foregoing embodiment describes the case where the fifth contact portion 83 contacts two first contacts 70a adjacent to each other in the right-left direction, the present disclosure is not limited to such. The fifth contact portion 83 may contact one first contact 70a or three or more first contacts 70a.
Although the foregoing embodiment describes the case where the fifth contact portion 83 of the second metal member 80 extends from the third base portion 82, the present disclosure is not limited to such. The fifth contact portion 83 may directly extend from the second base portion 81.
Although the foregoing embodiment describes the case where the third contact portion 73a and the sixth contact portion 74a are located at opposite ends of the first contact 70a in the extending direction of the plurality of contact lines 42, the present disclosure is not limited to such. The third contact portion 73a and the sixth contact portion 74a may be formed at any positions in the first contact 70a.
Although the foregoing embodiment describes the case where the second metal member 80 includes the elastically deformable seventh contact portion 87 that extends from the second base portion 81 and contacts the connection object 40, the present disclosure is not limited to such. The seventh contact portion 87 may not be elastically deformable. The second metal member 80 may not include the seventh contact portion 87 and may not contact the connection object 40.
Although the foregoing embodiment describes the case where two first contacts 70a are arranged between a plurality of second contacts 70b as illustrated in
The first contact portion 32 may not be notched in the thickness direction at the center of the part formed wide in the right-left direction, unlike in the first metal member 30 in
The second contact portion 33 may be formed as a projection that is located at the center of the part formed wide in the right-left direction in the first contact portion 32 and protrudes from the surface of the first contact portion 32. The second contact portion 33 may protrude from the surface of the first contact portion 32 so as to be circular in a top view.
In this case, the elastic deformation of the first contact 70a is reduced by the thickness of the first metal member 30 as compared with the case illustrated in
