In the drawings, the height direction T, the length direction L, and the width direction W of the multipolar connector group 100, the first connector 100A, and the second connector 100B are shown, and these directions may be mentioned in the following description. The first connector 100A and the second connector 100B each have a pair of end faces opposing each other in the longitudinal direction L, a pair of side faces opposing each other in the width direction W, and a pair of main faces (mounting face and fitting face) opposing each other in the height direction T.

As described above, the multipolar connector group 100 is configured by fitting the first connector 100A and the second connector 100B to each other. The first connector 100A, the second connector 100B, and the multipolar connector group 100 will be described in order below.

< first connector 100A >)

Fig. 1 (a), 1 (B), and 2 show a first connector 100A.

The first connector 100A includes a plurality of first internal terminals 1a to 1 n. The first inner terminals 1a to 1n are arranged in two rows of a first row C1 and a second row C2 extending in the longitudinal direction L. Specifically, the first inner terminals 1a to 1g are arranged in the first row C1, and the first inner terminals 1h to 1n are arranged in the second row C2.

The first internal terminals 1a to 1n are connected to a signal line, a ground line, and the like of a circuit board or the like on which the first connector 100A is mounted. In the present embodiment, the first internal terminals 1a to 1n are so-called male terminals having a convex shape. However, the first internal terminals 1a to 1n may be so-called female terminals having a concave shape.

The material of the first internal terminals 1a to 1n is arbitrary, and phosphor bronze, for example, can be used. Phosphor bronze is a material that has electrical conductivity and is elastically deformed.

In the present embodiment, the first internal terminals 1a to 1n are formed by bending a long metal plate. However, the first inner terminals 1a to 1n may be terminals formed by die-processing a metal member having elasticity.

The first connector 100A includes a first insulating member 2. The first insulating member 2 is a member for holding the first internal terminals 1a to 1 n. The material of the first insulating member 2 is arbitrary, and for example, resin can be used. The first inner terminals 1a to 1n are insert-molded to the first insulating member 2. However, the first inner terminals 1a to 1n may be embedded in and fixed to the first insulating member 2.

The first connector 100A is provided with first external terminals 3 at both ends of the first insulating member 2, respectively.

The first external terminal 3 is connected to a ground line of a circuit board or the like on which the first connector 100A is mounted. The first external terminal 3 shields the end face of the first connector 100A.

The first external terminal 3 has a pair of ground mounting portions 3a on the side surface side of the first connector 100A, and a pair of ground mounting portions 3b on the end surface side of the first connector 100A. The pair of ground mounting portions 3a extend in the same direction as the direction in which the first internal terminals 1a to 1n extend, respectively.

The material of the first external terminal 3 is arbitrary, and phosphor bronze, for example, can be used. The first external terminal 3 can be manufactured by any method, for example, punching and bending a single metal plate.

The first external terminal 3 is insert-molded to the first insulating member 2. However, the first external terminal 3 may be embedded in and fixed to the first insulating member 2.

The first connector 100A is provided with a first shield member 4 extending in the longitudinal direction L at a central portion in the width direction W of the first insulating member 2. The first shield member 4 has end portions 4h, 4i at both ends.

The first shielding member 4 is provided to suppress electromagnetic interference between the first inner terminals 1a to 1g arranged in the first row C1 and the first inner terminals 1h to 1n arranged in the second row C2.

The end portions 4h and 4i of the first shield member 4 penetrate below the first external terminal 3 and are exposed at the end face of the first connector 100A. Thus, the suppression of the electromagnetic interference between the first inner terminals 1a to 1g arranged in the first row C1 and the first inner terminals 1h to 1n arranged in the second row C2 by the first shielding member 4 is enhanced.

The ends 4h and 4i of the first shield member 4 may be connected to the second external terminal 7 of the second connector 100B when the first shield member 4 is fitted to the second connector 100B. In this case, the connectivity of the first shield member 4 with the ground wire can be enhanced.

The first shield member 4 has a connection portion 4a, and the connection portion 4a is connected to a second inner terminal 5c of a second connector 100B described later. In a state where the first connector 100A and the second connector 100B are fitted to each other, the connection portion 4a extends from the first shield member 4 in the direction of the second inner terminal 5 c.

The first shield member 4 has a connection portion 4B connected to a second inner terminal 5e of a second connector 100B described later. In a state where the first connector 100A and the second connector 100B are fitted to each other, the connection portion 4B extends from the first shield member 4 in the direction of the second inner terminal 5 e.

The first shield member 4 has a connection portion 4c connected to a second inner terminal 5j of a second connector 100B described later. In a state where the first connector 100A and the second connector 100B are fitted to each other, the connection portion 4c extends from the first shield member 4 in the direction of the second inner terminal 5 j.

The first shield member 4 has a connection portion 4d connected to a second inner terminal 5l of the second connector 100B described later. In a state where the first connector 100A and the second connector 100B are fitted to each other, the connection portion 4d extends from the first shield member 4 in the direction of the second inner terminal 5 l.

The first shield member 4 includes connection portions 4a to 4d for connecting the first shield member 4 and the first or second inner terminal inside the ground mounting portions 3a and 3b of the first outer terminal 3.

The ground mounting portion 3a of the first external terminal 3 has a shape extending outward of the first connector 100A along the end portions of the first internal terminals 1a to 1 n. Thus, the first inner terminals 1a to 1n (except the first inner terminals 1c, 1e, 1j, 1 l) are surrounded at their ends by the pair of first outer terminals 3, the first shield member 4, and the first inner terminals 1c, 1e, 1j, 1l connected to the first shield member 4, which are members having a ground potential, and therefore, interference of the first inner terminals 1a to 1n (except the first inner terminals 1c, 1e, 1j, 1 l) with external electromagnetic waves can be further suppressed. Further, by providing the ground mounting portion 3b between the ground mounting portion 3a and the first shielding member 4 in the width direction W, it is possible to further suppress interference of the first inner terminals 1a to 1n (except for the first inner terminals 1c, 1e, 1j, 1 l) with external electromagnetic waves.

The first shield member 4 has a projection 4e that fits into a recess 8a of a second shield member 8 of the second connector 100B described later.

The first shield member 4 has a projection 4f that fits into a recess 9a of a second shield member 9 of a second connector 100B described later.

The material of the first shield member 4 is arbitrary, and phosphor bronze, for example, can be used.

The first shield member 4 of the present embodiment is manufactured by punching and bending one metal plate. However, the first shield member 4 may also be manufactured by joining a plurality of members.

The first shield member 4 is insert-molded to the first insulating member 2. However, the first shielding member 4 may be embedded and fixed to the first insulating member 2.

The first connector 100A can be manufactured by a connector manufacturing method generally performed in the related art.

< second connector 100B >

Fig. 3 (a), 3 (B), and 4 show a second connector 100B.

The second connector 100B includes a plurality of second internal terminals 5a to 5 n. The second inner terminals 5a to 5n are arranged in two rows of a first row C1 and a second row C2 extending in the longitudinal direction L. Specifically, the second internal terminals 5a to 5g are arranged in the first row C1, and the second internal terminals 5h to 5n are arranged in the second row C2.

The second internal terminals 5a to 5n are connected to a signal line, a ground line, or the like of a circuit board or the like on which the second connector 100B is mounted. In the present embodiment, the second internal terminals 5a to 5n are so-called female terminals. However, the second internal terminals 5a to 5n may be so-called male terminals.

The material of the second inner terminals 5a to 5n is arbitrary, and phosphor bronze, for example, can be used.

In the present embodiment, the second inner terminals 5a to 5n are formed by bending a long metal plate. However, the second inner terminals 5a to 5n may be terminals formed by die-working a metal member having elasticity.

The second connector 100B includes a second insulating member 6. The second insulating member 6 is a member for holding the second inner terminals 5a to 5 n. The material of the second insulating member 6 is arbitrary, and for example, 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 be fitted and fixed to the second insulating member 6.

The second connector 100B includes a second external terminal 7 held by the second insulating member 6. The second external terminal 7 includes a pair of main bodies 7a disposed at both ends of the first insulating member 2, and a pair of side walls (side shields) 7b extending in the longitudinal direction L and connecting the pair of main bodies 7 a.

The second external terminal 7 is connected to a ground line of a circuit board or the like on which the second connector 100B is mounted. The body portion 7a shields an end face of the second connector 100B. The side wall portion 7B shields the side surface of the second connector 100B.

The material of the second external terminal 7 is arbitrary, and phosphor bronze, for example, can be used.

The second external terminal 7 of the present embodiment is integrally formed by punching and bending one metal plate. However, the second external terminal 7 may be formed by separately manufacturing the main body portion 7a and the side wall portion 7b and then joining them.

The second external terminal 7 is insert-molded into the second insulating member 6. However, the second external terminal may be embedded in and fixed to the second insulating member 6.

In the second connector 100B, two second shield members 8 and 9 extending in the longitudinal direction L are provided at the center in the width direction W of the second insulating member 6.

The second shielding members 8 and 9 are provided to suppress electromagnetic interference between the second inner terminals 5a to 5g arranged in the first row C1 and the second inner terminals 5h to 5n arranged in the second row C2.

The second shield member 8 has a concave portion 8a fitted to the convex portion 4e of the first shield member 4 of the first connector 100A.

The second shield member 9 has a concave portion 9a fitted to the convex portion 4f of the first shield member 4 of the first connector 100A.

The material of the second shield members 8 and 9 is arbitrary, and phosphor bronze, for example, can be used.

In the present embodiment, the second shield members 8 and 9 are formed by bending a long metal plate. However, the second shield members 8, 9 may be formed by die-working a metal member having elasticity.

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 be embedded in and fixed to the second insulating member 6.

The second connector 100B can be manufactured by a connector manufacturing method generally performed in the related art.

< multipolar connector group 100 >

The first connector 100A and the second connector 100B are fitted to each other to form the multipolar connector group 100. Fig. 5 is a perspective view of the multipolar connector group 100 in which the first connector 100A and the second connector 100B are fitted. Fig. 6 is a perspective view of the multipolar connector group 100 from which the fitting between the first connector 100A and the second connector 100B has been removed.

In the multipolar connector set 100, the first internal terminals 1a to 1n and the second internal terminals 5a to 5n are connected to each other in a state where the first connector 100A and the second connector 100B are fitted to each other. The first internal terminals 1a to 1n and the second internal terminals 5a to 5n are connected to each other by terminals having the same alphabet that constitute a part of the correspondence, like the first internal terminals 1a and the second internal terminals 5 a.

In the multipolar connector set 100, the first external terminal 3 is connected to the body portion 7a of the second external terminal 7 in a state where the first connector 100A and the second connector 100B are fitted to each other.

As shown in fig. 7, in the multipolar connector set 100, in a state where the first connector 100A and the second connector 100B are fitted to each other, the connection portion 4a of the first shield member 4 is connected to the second internal terminal 5c, the connection portion 4B is connected to the second internal terminal 5e, the connection portion 4c is connected to the second internal terminal 5j, and the connection portion 4d is connected to the second internal terminal 5 l.

More specifically, when the first connector 100A is fitted to the second connector 100B, the second inner terminals 5c press the connection portions 4a from both sides, the second inner terminals 5e press the connection portions 4B from both sides, the second inner terminals 5j press the connection portions 4c from both sides, and the second inner terminals 5l press the connection portions 4d from both sides.

That is, when the first connector 100A and the second connector 100B are fitted to each other, the contact point between the connection portion 4a and the second internal terminal 5c and the contact point between the first internal terminal 1c and the second internal terminal 5c are aligned in the extending direction of the second internal terminal 5 c. The contact point between the connecting portion 4b and the second internal terminal 5e and the contact point between the first internal terminal 1e and the second internal terminal 5e are aligned in the extending direction of the second internal terminal 5 e. A contact point between the connection portion 4c and the second internal terminal 5j and a contact point between the first internal terminal 1j and the second internal terminal 5j are aligned in the extending direction of the second internal terminal 5 j. The contact point between the connection portion 4d and the second internal terminal 5l and the contact point between the first internal terminal 1l and the second internal terminal 5l are aligned in the extending direction of the second internal terminal 5 l.

The second inner terminal 5c is connected to the connection portion 4a of the first shield member 4, and is brought into a ground potential together with the first inner terminal 1c, thereby exhibiting a shielding effect. The second internal terminals 5C and the first internal terminals 1C suppress electromagnetic interference between the first internal terminals 1b and the second internal terminals 5b, and the first internal terminals 1d and the second internal terminals 5d, which are arranged in the same first row C1. Further, the second internal terminal 5c and the first internal terminal 1c are also preferably connected to the ground.

The second internal terminal 5e is connected to the connection portion 4b of the first shield member 4, and becomes a ground potential together with the first internal terminal 1e, thereby exhibiting a shielding effect. The second internal terminal 5e and the first internal terminal 1e suppress electromagnetic interference between the first internal terminal 1d and the second internal terminal 5d, and the first internal terminal 1f and the second internal terminal 5f, which are arranged in the same first row C1. Further, the second internal terminal 5e and the first internal terminal 1e are also preferably connected to ground.

The second internal terminal 5j is connected to the connection portion 4c of the first shield member 4, and becomes a ground potential together with the first internal terminal 1j, thereby exhibiting a shielding effect. The second internal terminal 5j and the first internal terminal 1j suppress electromagnetic interference between the first internal terminal 1i and the second internal terminal 5i, and the first internal terminal 1k and the second internal terminal 5k, which are arranged in the same second row C2. Further, the second internal terminal 5j and the first internal terminal 1j are also preferably connected to the ground.

The second inner terminal 5l is connected to the connection portion 4d of the first shield member 4, and is brought into a ground potential together with the first inner terminal 1l, thereby exhibiting a shield effect. The second internal terminal 5l and the first internal terminal 1l suppress electromagnetic interference between the first internal terminal 1k and the second internal terminal 5k, which are arranged in the same second row C2, and the first internal terminal 1m and the second internal terminal 5 m. Further, the second internal terminal 5l and the first internal terminal 1l are also preferably connected to ground, respectively.

As described above, in the multipolar connector set 100, the first shielding member 4 is connected to the second internal terminals 5c, 5e, 5j, and 5l in a state where the first connector 100A and the second connector 100B are fitted to each other, and therefore, electromagnetic interference between the internal terminals arranged in the same row can be suppressed.

As shown in fig. 7, in the multipolar connector set 100, in a state where the first connector 100A and the second connector 100B are fitted to each other, the convex portion 4e of the first shield member 4 is fitted to the concave portion 8a of the second shield member 8, and the convex portion 4f of the first shield member 4 is fitted to the concave portion 9a of the second shield member 9. As a result, the first shield member 4 is connected to the second shield member 8, and the first shield member 4 is connected to the second shield member 9.

In fig. 8, respective isolation characteristics are shown for an embodiment in which the first shielding member 4 is connected to the second internal terminals 5c, 5e, 5j, 5l and a comparative example in which the first shielding member 4 is not connected to the second internal terminals 5c, 5e, 5j, 5 l. As can be seen from fig. 8, the embodiment in which the first shielding member 4 is connected to the second inner terminals 5c, 5e, 5j, 5l improves the isolation characteristic compared to the non-connected comparative example.

[ second embodiment ]

Fig. 9 to 13 show a multipolar connector set 200 according to a second embodiment. The multipolar connector set 200 is configured by fitting the first connector 200A and the second connector 200B to each other. Fig. 9 is a perspective view of the first connector 200A as viewed from the mating surface side. Fig. 10 is an exploded perspective view of the first connector 200A. Fig. 11 is a perspective view of the second connector 200B as viewed from the mating surface side. Fig. 12 is an exploded perspective view of the second connector 200B. Fig. 13 is a sectional perspective view and a main portion sectional view of the multipolar connector set 200 divided in the width direction W.

The multipole connector set 200 of the second embodiment is a modification of the partial structure of the multipole connector set 100 of the first embodiment. Specifically, in the multipolar connector group 100, the connection portions 4a to 4d are formed in the first shield member 4, the connection portion 4a is connected to the second internal terminal 5c, the connection portion 4b is connected to the second internal terminal 5e, the connection portion 4c is connected to the second internal terminal 5j, and the connection portion 4d is connected to the second internal terminal 5 l. In the multipolar connector group 200, a connection portion is formed on the second inner terminal side, and the formed connection portion is connected to the first shield member 24.

The multipolar connector set 200 omits the connection portions 4a to 4d formed in the first shield member 4 of the multipolar connector set 100 from the first shield member 24, and instead forms a connection plate 24 g.

In the multipolar connector set 200, second internal terminals 25b, 25d, 25f, 25i, 25k, and 25m having different shapes are used instead of the second internal terminals 5b, 5d, 5f, 5i, 5k, and 5m of the multipolar connector set 100. The second inner terminals 25b, 25d, 25f, 25i, 25k, and 25m are each provided at the tip with a connection portion 21 for connection to the connection plate 24g of the first shield member 24.

In the multipolar connector set 200, in a state where the first connector 200A and the second connector 200B are fitted to each other, the connection portion 21 of the second internal terminal 25B, the connection portion 21 of the second internal terminal 25d, the connection portion 21 of the second internal terminal 25f, the connection portion 21 of the second internal terminal 25i, the connection portion 21 of the second internal terminal 25k, and the connection portion 21 of the second internal terminal 25m are connected to the connection plate 24g of the first shield member 24, respectively.

In the multipolar connector set 200, the first shielding member 24 is also connected to the second internal terminals 25b, 25d, 25f, 25i, 25k, and 25m, so that electromagnetic interference between the internal terminals arranged in the same row can be suppressed.

[ third embodiment ]

Fig. 14 to 18 show a multipolar connector set 300 according to a third embodiment. The multipolar connector set 300 is configured by fitting the first connector 300A and the second connector 300B to each other. Fig. 14 is a perspective view of the first connector 300A as viewed from the mating surface side. Fig. 15 is an exploded perspective view of the first connector 300A. Fig. 16 is a perspective view of the second connector 300B as viewed from the mating surface side. Fig. 17 is an exploded perspective view of the second connector 300B. Fig. 18 is a sectional perspective view and a main portion sectional view of the multipolar connector set 300 divided in the width direction W.

The multipole connector set 300 of the third embodiment further modifies the multipole connector set 200 of the second embodiment. Specifically, in the multipolar connector group 200, the second internal terminals 25b, 25d, 25f, 25i, 25k, 25m are not connected to the second external terminal 7. The multipolar connector set 300 uses second inner terminals 35b, 35d, 35f, 35i, 35k, and 35m connected to the side wall portion 7b of the second outer terminal 7, respectively, instead of the second inner terminals 25b, 25d, 25f, 25i, 25k, and 25m of the multipolar connector set 200. The second inner terminals 35b, 35d, 35f, 35i, 35k, 35m have connection portions 31 formed at the front ends thereof.

In addition, the multipolar connector set 300 omits the second shielding members 8, 9 from the second connector 300B. In the multipolar connector 300, the first shield member 34 in which the projections 4e and 4f are omitted and the larger connection plate 34g is formed is used in the first connector 300A.

In the multipolar connector set 300, in a state where the first connector 300A and the second connector 300B are fitted to each other, the connection portion 31 of the second inner terminal 35B, the connection portion 31 of the second inner terminal 35d, the connection portion 31 of the second inner terminal 35f, the connection portion 31 of the second inner terminal 35i, the connection portion 31 of the second inner terminal 35k, and the connection portion 31 of the second inner terminal 35m are connected to the connection plate 34g of the first shield member 34, respectively.

In the multipolar connector set 300, the first shielding member 34 is connected to the second internal terminals 35b, 35d, 35f, 35i, 35k, and 35m, and therefore, electromagnetic interference between the internal terminals arranged in the same row can be suppressed.

In the multipolar 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, so that the shielding effect is further improved.

The multipole connector groups 100, 200, 300 of the first to third embodiments have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made in accordance with the gist of the present invention.

For example, in the first to third embodiments, the first shield member is connected to the second internal terminal, but the first shield member may be connected to the first internal terminal instead of or in addition to the second internal terminal.

The multipolar connector group according to one embodiment of the present invention is as described in the section of "summary of the invention".

In the present multipolar connector set, it is also preferable that the first shield member has a connection portion extending from the first shield member in a direction toward the first internal terminal or in a direction toward the second internal terminal. Alternatively, it is also preferable that the second inner terminal has a connection portion extending from the second inner terminal in a direction toward the first shield member.

Further, it is preferable that the second connector has a rectangular shape extending in the longitudinal direction, the second connector further includes a second external terminal held by the second insulating member, the second external terminal has two side wall portions extending in the longitudinal direction and facing each other, at least one of the second internal terminals is connected to the side wall portion, and the second internal terminal has a connecting portion extending from the second internal terminal connected to the side wall portion in the direction of the first shield member. In this case, since the first shield member, the second inner terminal, and the second outer terminal are connected to each other, the shielding effect is improved.

Preferably, the first connector further includes a first external terminal held by the first insulating member, the second connector further includes a second external terminal held by the second insulating member, and the first shield member passes under the first external terminal and extends to the second external terminal. In this case, suppression of electromagnetic interference between the internal terminals arranged in different rows by the first shielding member is enhanced.

Further, it is also preferable that the second connector has a second inner terminal that presses the first shield member from both sides in the extending direction of the first inner terminal. In this case, the first shield member and the second inner terminal are reliably connected.

Further, it is also preferable that the second connector further includes a second shield member positioned between the rows of the second internal terminals, and the second shield member is connected to the first shield member. In this case, it is possible to further suppress electromagnetic interference between the internal terminals arranged in different rows.

Preferably, the first internal terminal is a male terminal, and the second internal terminal is a female terminal. In this case, for example, when a connection portion is provided at the tip of the second inner terminal and the connection portion is brought into contact with and connected to the first shield member, the connection portion elastically comes into contact with the first shield member, and therefore the second inner terminal and the first shield member can be connected favorably.
