This application claims benefit of priority to International Patent Application No. PCT/JP2020/017412, filed Apr. 22, 2020, and to Japanese Patent Application No. 2019-083476, filed Apr. 24, 2019, the entire contents of each are incorporated herein by reference.
The present disclosure relates to a multi-pole connector set formed by inner terminals of a first connector and a second connector connecting to each other.
Heretofore, a multi-pole connector set is known that is configured so that a first connector is connected to one circuit board, a second connector is connected to another circuit board, and inner terminals of the first connector and the second connector are connected to each other in order to electrically connect the two circuit boards to each other as described, for example, in International Publication No. 2019/021611.
In the multi-pole connector set of International Publication No. 2019/021611, first inner terminals of the first connector are disposed in two rows. In addition, second inner terminals of the second connector are disposed in two rows.
A shield member is provided between the rows of inner terminals in the multi-pole connector set of International Publication No. 2019/021611. In the multi-pole connector set of International Publication No. 2019/021611, electromagnetic wave interference between inner terminals disposed in different rows is suppressed by the shield member.
In the multi-pole connector set of International Publication No. 2019/021611, electromagnetic wave interference between inner terminals disposed in different rows is suppressed by the shield member. However, electromagnetic wave interference between inner terminals disposed in the same rows is not adequately suppressed.
Accordingly, the present disclosure provides a multi-pole connector set in which electromagnetic wave interference between inner terminals disposed in the same rows is suppressed. Note that “connector set” refers to a connector set having a large number of terminals.
An embodiment of the present disclosure provides a multi-pole connector set formed by inner terminals of a first connector and a second connector connecting to each other. The first connector includes first inner terminals arrayed in a plurality of rows, a first insulating member that holds the first inner terminals, and a first shield member that is located between the rows of the first inner terminals. The second connector includes second inner terminals arrayed in a plurality of rows, and a second insulating member that holds the second inner terminals. The multi-pole connector set further includes a connection part that connects the first shield member and the first inner terminals or the second inner terminals to each other.
According to the multi-pole connector set of the present disclosure, electromagnetic wave interference between inner terminals disposed in the same rows is suppressed.
Hereafter, modes for carrying out the present disclosure will be described together with the drawings.
The embodiments illustrate modes for carrying out the present disclosure in an exemplary manner, and the present disclosure is not limited to the content of the embodiments. In addition, it is possible to combine contents described in different embodiments and the embodiments realized in this way are also included in the present disclosure. In addition, the drawings are to aid in the understanding of the specification and may be drawn in a schematic manner, and the dimensional ratios of the drawn constituent elements or between the drawn constituent elements may not match the corresponding dimensional ratios described in the specification. In addition, constituent elements described in the specification may be omitted from the drawings, may be drawn as being fewer in number, and so forth.
A height direction T, a length direction L, and a width direction W of the multi-pole connector set 100, the first connector 100A, and the second connector 100B are illustrated in the drawings and these directions may be referred to in the description below. The first connector 100A and the second connector 100B each include a pair of end surfaces that face each other in the length direction L, a pair of side surfaces that face each other in the width direction W, and a pair of main surfaces (a mounting surface and a mating surface) that face each other in the height direction T.
As described above, the multi-pole connector set 100 is configured so that the first connector 100A and the second connector 100B mate with each other. Hereafter, the first connector 100A, the second connector 100B, and the multi-pole connector set 100 will be described in this order.
First Connector 100A
The first connector 100A is illustrated in
The first connector 100A includes a plurality of first inner terminals 1a to 1n. The first inner terminals 1a to 1n are disposed in two rows, namely, a first row C1 and a second row C2 that extend in the length direction L. Specifically, the first inner terminals 1a to 1g are disposed in the first row C1 and the first inner terminals 1h to 1n are disposed in the second row C2.
The first inner terminals 1a to 1n are connected to signal lines, a ground, and so on of a circuit board or the like on which the first connector 100A is mounted. In this embodiment, the first inner terminals 1a to 1n are so-called male terminals having a convex shape. However, the first inner terminals 1a to 1n may instead be so-called female terminals having a concave shape.
The material of the first inner terminals 1a to 1n is chosen as appropriate, and phosphor bronze can be used, for example. Phosphor bronze is a material that is electrically conductive and elastically deformable.
In this embodiment, the first inner terminals 1a to 1n are composed of members manufactured by bending and processing metal strips. However, the first inner terminals 1a to 1n may instead be manufactured by die-cutting a metal member having springiness.
The first connector 100A includes a first insulating member 2. The first insulating member 2 is a member that is for holding the first inner terminals 1a to 1n. The material of first insulating member 2 is chosen as appropriate, and for example, a resin can be used. The first inner terminals 1a to 1n are insert molded into the first insulating member 2. However, the first inner terminals 1a to 1n may instead be fitted and fixed to the first insulating member 2.
The first connector 100A is provided with first outer terminals 3 at both ends of the first insulating member 2.
The first outer terminals 3 are connected to a ground of a circuit board or the like on which the first connector 100A is mounted. The first outer terminals 3 shield the end surfaces of the first connector 100A.
The first outer terminals 3 have a pair of ground mounting parts 3a on the sides thereof near the side surfaces of the first connector 100A and have a pair of ground mounting parts 3b on the sides thereof near the end surfaces of the first connector 100A. The pair of ground mounting parts 3a extend in the same direction as the direction in which the first inner terminals 1a to 1n extend.
The material of the first outer terminals 3 is chosen as appropriate, and phosphor bronze can be used, for example. The method of manufacturing the first outer terminals 3 is chosen as appropriate, and for example, the first outer terminals 3 can be manufactured by punching and bending a metal plate.
The first outer terminals 3 are insert molded into the first insulating member 2. However, the first outer terminals 3 may instead be fitted and fixed to the first insulating member 2.
In the first connector 100A, a first shield member 4 that extends in the length direction L is provided at a central part of the first insulating member 2 in the width direction W. The first shield member 4 end portions 4h and 4i at both ends thereof.
The first shield member 4 is provided in order to suppress electromagnetic wave interference between the first inner terminals 1a to 1g disposed in the first row C1 and the first inner terminals 1h to 1n disposed in the second row C2.
The end portions 4h and 4i of first shield member 4 are exposed at the end surfaces of the first connector 100A underneath the first outer terminals 3. As a result, suppression of electromagnetic wave interference between the first inner terminals 1a to 1g disposed in the first row C1 and the first inner terminals 1h to 1n disposed in the second row C2 is increased by the first shield member 4.
The end portions 4h and 4i of the first shield member 4 may be connected to a second outer terminal 7 of the second connector 100B when the first shield member 4 and the second connector 100B are interlocked. In this case, the connection between the first shield member 4 and the ground can be strengthened.
The first shield member 4 has a connection part 4a that connects to a second inner terminal 5c of the second connector 100B, which will be described later. The connection part 4a extends in a direction toward the second inner terminal 5c from the first shield member 4 in a state where the first connector 100A and the second connector 100B are mated with each other.
The first shield member 4 has a connection part 4b that connects to a second inner terminal 5e of the second connector 100B, which will be described later. The connection part 4b extends in a direction toward the second inner terminal 5e from the first shield member 4 in a state where the first connector 100A and the second connector 100B are mated with each other.
The first shield member 4 has a connection part 4c that connects to a second inner terminal 5j of the second connector 100B, which will be described later. The connection part 4c extends in a direction toward the second inner terminal 5j from the first shield member 4 in a state where the first connector 100A and the second connector 100B are mated with each other.
The first shield member 4 has a connection part 4d that connects to a second inner terminal 5l of the second connector 100B, which will be described later. The connection part 4d extends in a direction toward the second inner terminal 5l from the first shield member 4 in a state where the first connector 100A and the second connector 100B are mated with each other.
The first shield member 4 is provided with the connection parts 4a to 4d, which connect the first shield member 4 and the first inner terminals or the second inner terminals to each other, nearer the inside than the ground mounting parts 3a and 3b of the first outer terminals 3.
The ground mounting parts 3a of the first outer terminals 3 are shaped so as to extend outward towards the region outside the first connector 100A and so as to be aligned with the end portions of the first inner terminals 1a to 1n. Thus, since the first inner terminals 1a to 1n (except for the first inner terminals 1c, 1e, 1j, and 1l) are surrounded up to their end portions by members that are at the ground potential, namely, the pair of first outer terminals 3, the first shield member 4, and the first inner terminals 1c, 1e, 1j, and 1l, which are connected to the first shield member 4, electromagnetic wave interference between the first inner terminals 1a to 1n (except for the first inner terminals 1c, 1e, 1j, and 1l) and the outside is further suppressed. In addition, electromagnetic wave interference between the first inner terminals 1a to 1n (except for the first inner terminals 1c, 1e, 1j, and 1l) and the outside is further suppressed by providing the ground mounting parts 3b between the ground mounting parts 3a and the first shield member 4 in the width direction W.
In addition, the first shield member 4 has a protrusion 4e that mates with a recess 8a of a second shield member 8 of the second connector 100B that will be described later.
The first shield member 4 has a protrusion 4f that mates with a recess 9a of a second shield member 9 of the second connector 100B that will be described later.
The material of the first shield member 4 is chosen as appropriate, and phosphor bronze can be used, for example.
The first shield member 4 of this embodiment is manufactured by punching and bending a metal plate. However, the first shield member 4 may instead be manufactured by joining together a plurality of members.
The first shield member 4 is insert molded into the first insulating member 2. However, the first shield member 4 may instead be fitted and fixed to the first insulating member 2.
The first connector 100A can be manufactured using an existing generally used connector manufacturing method.
Second Connector 100B
The second connector 100B is illustrated in
The second connector 100B includes a plurality of second inner terminals 5a to 5n. The second inner terminals 5a to 5n are disposed in two rows, namely, a first row C1 and a second row C2 that extend in the length direction L. Specifically, the second inner terminals 5a to 5g are disposed in the first row C1 and the second inner terminals 5h to 5n are disposed in the second row C2.
The second inner terminals 5a to 5n are connected to signal lines, a ground, and so on of the circuit board or the like on which the second connector 100B is mounted. In this embodiment, the second inner terminals 5a to 5n are so-called female terminals. However, the second inner terminals 5a to 5n may instead be so-called male terminals.
The material of the second inner terminals 5a to 5n is chosen as appropriate, and phosphor bronze can be used, for example.
In this embodiment, the second inner terminals 5a to 5n are composed of members manufactured by bending and processing metal strips. However, the second inner terminals 5a to 5n may instead be manufactured by die-cutting a metal member having springiness.
The second connector 100B includes a second insulating member 6. The second insulating member 6 is a member that is for holding the second inner terminals 5a to 5n. The material of second insulating member 6 is chosen as appropriate, and for example, a resin can be used. The second inner terminals 5a to 5n are insert molded into the second insulating member 6. However, the second inner terminals 5a to 5n may instead be fitted and fixed to the second insulating member 6.
The second connector 100B includes a second outer terminal 7 held by the second insulating member 6. The second outer terminal 7 has a pair of body parts 7a that are disposed at both ends of the first insulating member 2 and a pair of side wall parts (side shields) 7b that extend in the length direction L and connect the pair of body parts 7a to each other.
The second outer terminal 7 is connected to a ground of a circuit board or the like on which the second connector 100B is mounted. The body parts 7a shield the end surfaces of the second connector 100B. The side wall parts 7b shield the side surfaces of the second connector 100B.
The material of the second outer terminal 7 is chosen as appropriate, and phosphor bronze can be used, for example.
The second outer terminal 7 of this embodiment is basically manufactured by punching and bending a metal plate. However, the body parts 7a and the side wall parts 7b of the second outer terminal 7 may instead be manufactured separately and then joined together.
The second outer terminal 7 is insert molded into the second insulating member 6. However, the second outer terminal may instead be fitted and fixed to the second insulating member 6.
In the second connector 100B, two second shield members 8 and 9 that extend in the length direction L are provided at a central part of the second insulating member 6 in the width direction W.
The second shield members 8 and 9 are provided in order to suppress electromagnetic wave interference between the second inner terminals 5a to 5g disposed in the first row C1 and the second inner terminals 5h to 5n disposed in the second row C2.
The second shield member 8 includes the recess 8a that mates with the protrusion 4e of the first shield member 4 of the first connector 100A.
The second shield member 9 includes the recess 9a that mates with the protrusion 4f of the first shield member 4 of the first connector 100A.
The material of the second shield members 8 and 9 is chosen as appropriate, and phosphor bronze can be used, for example.
In this embodiment, the second shield members 8 and 9 are composed of members manufactured by bending and processing metal strips. However, the second shield members 8 and 9 may instead be manufactured by die-cutting a metal member having springiness.
The second shield members 8 and 9 are insert molded into the second insulating member 6. However, the second shield members 8 and 9 may instead be fitted and fixed to the second insulating member 6.
The second connector 100B can be manufactured using an existing generally used connector manufacturing method.
Multi-Pole Connector Set 100
The multi-pole connector set 100 is formed by the first connector 100A and the second connector 100B mating with each other.
In a state where the first connector 100A and the second connector 100B of the multi-pole connector set 100 are mated with each other, the first inner terminals 1a to 1n and the second inner terminals 5a to 5n are respectively connected to each other. The first inner terminals 1a to 1n and the second inner terminals 5a to 5n having the same letters of the alphabet included in the symbols thereof, such as the first inner terminal 1a and the second inner terminal 5a, are connected to each other.
In addition, in the multi-pole connector set 100, in a state where the first connector 100A and the second connector 100B are mated with each other, the first outer terminals 3 and the body parts 7a of the second outer terminal 7 are connected to each other.
In addition, as illustrated in
More specifically, when the first connector 100A and the second connector 100B are mated with each other, the second inner terminal 5c presses against the connection part 4a from both sides, the second inner terminal 5e presses against the connection part 4b from both sides, the second inner terminal 5j presses against the connection part 4c from both sides, and the second inner terminal 5l presses against the connection part 4d from both sides.
In other words, when the first connector 100A and the second connector 100B are mated with each other, the connection point between the connection part 4a and the second inner terminal 5c and the connection point between the first inner terminal 1c and the second inner terminal 5c are lined up in a direction in which the second inner terminal 5c extends. The connection point between the connection part 4b and the second inner terminal 5e and the connection point between the first inner terminal 1e and the second inner terminal 5e are lined up in the direction in which the second inner terminal 5e extends. The connection point between the connection part 4c and the second inner terminal 5j and the connection point between the first inner terminal 1j and the second inner terminal 5j are lined up in the direction in which the second inner terminal 5j extends. The connection point between the connection part 4d and the second inner terminal 5l and the connection point between the first inner terminal 1l and the second inner terminal 5l are lined up in the direction in which the second inner terminal 5l extends.
The second inner terminal 5c is connected to the connection part 4a of the first shield member 4 and consequently is at the ground potential along with the first inner terminal 1c, and realizes a shielding effect. The second inner terminal 5c and the first inner terminal 1c suppress electromagnetic wave interference between the first inner terminal 1b and the second inner terminal Sb and the first inner terminal 1d and the second inner terminal 5d, which are disposed in the same first row C1. The second inner terminal 5c and the first inner terminal 1c are also both preferably connected to ground.
The second inner terminal 5e is connected to the connection part 4b of the first shield member 4 and consequently is at the ground potential along with the first inner terminal 1e, and realizes a shielding effect. The second inner terminal 5e and the first inner terminal 1e suppress electromagnetic wave interference between the first inner terminal 1d and the second inner terminal 5d and the first inner terminal if and the second inner terminal 5f, which are disposed in the same first row C1. The second inner terminal 5e and the first inner terminal 1e are also both preferably connected to ground.
The second inner terminal 5j is connected to the connection part 4c of the first shield member 4 and consequently is at the ground potential along with the first inner terminal 1j, and realizes a shielding effect. The second inner terminal 5j and the first inner terminal 1j suppress electromagnetic wave interference between the first inner terminal 1i and the second inner terminal 5i and the first inner terminal 1k and the second inner terminal 5k, which are disposed in the same second row C2. The second inner terminal 5j and the first inner terminal 1j are also both preferably connected to ground.
The second inner terminal 5l is connected to the connection part 4d of the first shield member 4 and consequently is at the ground potential along with the first inner terminal 1l, and realizes a shielding effect. The second inner terminal 5l and the first inner terminal 1l suppress electromagnetic wave interference between the first inner terminal 1k and the second inner terminal 5k and the first inner terminal 1m and the second inner terminal 5m, which are disposed in the same second row C2. The second inner terminal 5l and the first inner terminal 1l are also both preferably connected to ground.
As described above, in the multi-pole connector set 100, since the first shield member 4 is connected to the second inner terminals 5c, 5e, 5j, and 5l in the state where the first connector 100A and the second connector 100B are mated with each other, electromagnetic wave interference between inner terminals disposed in the same rows is suppressed.
Furthermore, in the multi-pole connector set 100, as illustrated in
The isolation characteristics of an example in which the first shield member 4 is connected to the second inner terminals 5c, 5e, 5j, and 5l and a comparative example in which the first shield member 4 is not connected to the second inner terminals 5c, 5e, 5j, and 5l are illustrated in
A multi-pole connector set 200 according to a Second Embodiment is illustrated in
The multi-pole connector set 200 according to the Second Embodiment has a configuration obtained by changing parts of the configuration of the multi-pole connector set 100 according to the First Embodiment. Specifically, in the multi-pole connector set 100, the connection parts 4a to 4d are formed on the first shield member 4, the connection part 4a is connected to the second inner terminal 5c, the connection part 4b is connected to the second inner terminal 5e, the connection part 4c is connected to the second inner terminal 5j, and the connection part 4d is connected to the second inner terminal 5l. In the multi-pole connector set 200, this is changed and connection parts are formed on the second inner terminals and the formed connection parts are connected to a first shield member 24.
In the multi-pole connector set 200, the connection parts 4a to 4d formed on the first shield member 4 of the multi-pole connector set 100 are omitted from the first shield member 24, and a connection plate 24g is formed instead.
In addition, in the multi-pole connector set 200, second inner terminals 25b, 25d, 25f, 25i, 25k, and 25m having different shapes are used instead of the second inner terminals 5b, 5d, 5f, 5i, 5k, and 5m of the multi-pole connector set 100. Connection parts 21, which are for connecting to the connection plate 24g of the first shield member 24, are formed at the tips of the second inner terminals 25b, 25d, 25f, 25i, 25k, and 25m.
In the multi-pole connector set 200, in the state in which the first connector 200A and the second connector 200B are mated with each other, the connection part 21 of the second inner terminal 25b, the connection part 21 of the second inner terminal 25d, the connection part 21 of the second inner terminal 25f, the connection part 21 of the second inner terminal 25i, the connection part 21 of the second inner terminal 25k, and the connection part 21 of the second inner terminal 25m are connected to the connection plate 24g of the first shield member 24.
In the multi-pole connector set 200 as well, since the first shield member 24 is connected to the second inner terminals 25b, 25d, 25f, 25i, 25k, and 25m, electromagnetic wave interference between inner terminals disposed in the same rows is suppressed.
A multi-pole connector set 300 according to a Third Embodiment is illustrated in
The multi-pole connector set 300 according to the Third Embodiment has a configuration obtained by making further changes to the configuration of the multi-pole connector set 200 according to the Second Embodiment. Specifically, in the multi-pole connector set 200, the second inner terminals 25b, 25d, 25f, 25i, 25k, and 25m are not connected to the second outer terminal 7. In the multi-pole connector set 300, second inner terminals 35b, 35d, 35f, 35i, 35k, and 35m that are connected to the side wall parts 7b of the second outer terminal 7 are used instead of the second inner terminals 25b, 25d, 25f, 25i, 25k, and 25m of the multi-pole connector set 200. Connection parts 31 are formed at the tips of the second inner terminals 35b, 35d, 35f, 35i, 35k, and 35m.
In addition, the second shield members 8 and 9 are omitted from the second connector 300B in the multi-pole connector set 300. Furthermore, in the multi-pole connector set 300, the protrusion 4e and 4f are omitted and a first shield member 34 in which a larger connection plate 34g is formed is used in the first connector 300A.
In the multi-pole connector set 300, in the state in which the first connector 300A and the second connector 300B are mated with each other, the connection part 31 of the second inner terminal 35b, the connection part 31 of the second inner terminal 35d, the connection part 31 of the second inner terminal 35f, the connection part 31 of the second inner terminal 35i, the connection part 31 of the second inner terminal 35k, and the connection part 31 of the second inner terminal 35m are connected to the connection plate 34g of the first shield member 34.
Since the first shield member 34 is connected to the second inner terminals 35b, 35d, 35f, 35i, 35k, and 35m, electromagnetic wave interference between inner terminals disposed in the same rows is suppressed in the multi-pole connector set 300.
In addition, in the multi-pole connector set 300, the second inner terminals 35b, 35d, 35f, 35i, 35k, and 35m are connected to the second outer terminal 7 and the first shield member 34, the first inner terminals 1b, 1d, 1f, 1i, 1k, and 1m, the second inner terminals 35b, 35d, 35f, 35i, 35k, and 35m, and the second outer terminal 7 are connected to each other, and therefore the shielding effect is further improved.
The multi-pole connector sets 100, 200, and 300 according to the first to Third Embodiments have been described above. However, the present disclosure is not limited to the above-described content and can be modified in various ways within the spirit of the disclosure.
For example, in the First to Third Embodiments, the first shield member is connected to the second inner terminals, but alternatively, the first shield member may be connected to the first inner terminals instead of or in addition to the second inner terminals.
A multi-pole connector set according to an embodiment of the present disclosure is described in the section “Means for Solving the Problem”.
In the multi-pole connector set, a first shield member preferably includes a connection part, and the connection part preferably extends from the first shield member in a direction toward first inner terminals or second inner terminals. Alternatively, the second inner terminals preferably have connection parts and the connection parts preferably extend from the second inner terminals in a direction toward the first shield member.
In addition, it is preferable that the second connector have a rectangular shape that extends in a length direction, that the second connector further include a second outer terminal that is held by a second insulating member, that the second outer terminal include two side wall parts that extend in the length direction and face each other, that one or more of the second inner terminals be connected to the side wall parts, that the second inner terminals have connection parts, and that the connection parts extend in a direction toward the first shield member from the second inner terminals connected to the side wall parts. In this case, the first shield member, the second inner terminals, and the second outer terminal are connected to each other, and therefore the shielding effect is improved.
Furthermore, it is preferable that the first connector further include a first outer terminal that is held by a first insulating member, that the second connector further include a second outer terminal that is held by a second insulating member, and that the first shield member extend underneath the first outer terminal up to the second outer terminal. In this case, suppression of electromagnetic wave interference between inner terminals disposed in different rows is strengthened by the first shield member.
Furthermore, it is preferable that the second connector have second inner terminals that press against the first shield member from both sides in a direction in which the first inner terminals extend. In this case, the first shield member and the second inner terminals are reliably connected.
In addition, it is preferable that the second connector further include a second shield member that is located between rows of the second inner terminals and that the second shield member be connected to the first shield member. In this case, electromagnetic wave interference between inner terminals disposed in different rows is further suppressed.
In addition, it is preferable that the first inner terminals be male terminals and that the second inner terminals be female terminals. In this case, for example, when the connection parts are provided at the tips of the second inner terminals and the connection parts abut against and are connected to the first shield member, the connection parts abut against the first shield member with springiness so that the second inner terminals and the first shield member are well connected.
