  However, in the conventional multipolar coaxial connector disclosed in Patent Document 1, the pair of contact pieces of the receptacle signal core wire and the pair of contact pieces of the shield for the receptacle core wire are in the same direction. It has become.

  For this reason, the opening and closing allowance provided for the pair of contact pieces of the receptacle signal core wire and the opening and closing allowance provided for the pair of contact pieces of the shield for the receptacle core wire overlap in the same direction, and as a result, the plug side and the receptacle There is a problem that the width of both coupling portions on the side becomes large and the size of the multipolar coaxial connector is increased.

  In particular, in a multipolar coaxial connector in which a plurality of coaxial cables are arranged side by side, the increased width of the coupling portion is accumulated in the parallel arrangement direction, which necessitates further enlargement of the multipolar coaxial connector. .

  Therefore, an object of the present invention is to obtain a multipolar coaxial connector that can be miniaturized with a relatively simple configuration.

  In the invention of claim 1, it has a signal post connected to the inner conductor serving as the signal line of the coaxial cable, and a ground post connected to the outer conductor serving as the ground line of the coaxial cable.

Is a multipole coaxial system In the connector, each of the signal posts and the ground posts is formed by a single conductive plate, and the signal posts and the ground posts are arranged to face each other in a direction perpendicular to each parallel arrangement direction with an insulating block interposed therebetween. In addition, the signal contact and the ground contact are each formed by a single conductive plate, and the signal contact and the ground contact sandwich the outside of the signal post and the ground post arranged oppositely with elasticity. It is characterized by being opposed to each other.

  In the invention of claim 2, the connecting portion connecting the ground post and the outer conductor of the coaxial cable is disposed on one side of the coaxial cable in a direction perpendicular to the parallel arrangement direction. And

A plurality of locations displaced in the vertical direction are fixed by caulking, and the insulating block is formed with concave portions for accommodating the caulking pieces in the arrangement portions of the caulking pieces.

  In the invention of claim 4, a cable unit is configured to include the coaxial cable, the signal post, the ground post, and the insulating block, and the cable units adjacent to each other are arranged in a direction in which they are arranged in parallel. It is characterized by being arranged in a staggered manner with a predetermined amount of deviation in the direction perpendicular to it.

  In the invention of claim 5, for the two cable units adjacent to each other, each ground post is disposed on a side away from the other cable unit in the right-angle direction, and the signal post and the ground The center of the tip portion where the post is disposed is set at the same height.

  In the invention of claim 6, the connecting part has a connecting part soldered to the outer conductor of the coaxial cable, and a through hole or a groove is formed in the connecting part.

The pitch of the parallel arrangement can be reduced as much as it is possible to reduce the pitch of the parallel arrangement, because it is not necessary to superimpose in the parallel arrangement direction and arrange in the direction perpendicular to the parallel arrangement direction. Miniaturization can be achieved by narrowing the width in the arrangement direction.

  In addition, since the signal post and the ground post arranged opposite to each other are elastically sandwiched between the signal contact and the ground contact arranged opposite to each other in the same direction, the signal post, the signal contact, and the ground post are arranged. It becomes easy to maintain the contact pressure with the ground contact between individuals, and the contact reliability can be improved.

  According to the invention of claim 3, the plurality of crimping pieces projecting at positions shifted in the length direction from the both sides of the connecting portion, and the plurality of positions shifted in the length direction of the insulating block are crimped. Since the fixing pieces are housed in the recesses formed in the insulating block, when the insulating block and the connecting portion are fixed, the portions where the crimping pieces exist on both sides of the insulating block can be eliminated. Accordingly, the pitch in the parallel arrangement direction can be reduced, and the width of the multipolar coaxial connector in the parallel arrangement direction can be narrowed to achieve downsizing.

  According to the invention of claim 4, since the cable units adjacent to each other are arranged in a staggered manner, the pitch in the parallel arrangement direction can be reduced as compared with the case where the cable units are arranged in a line. Miniaturization can be achieved by narrowing the width of the polar coaxial connector in the parallel arrangement direction.

It becomes easy to ensure, and the pitch of a cable unit can be set smaller.

  Furthermore, since the center of the tip of the cable unit is set at the same height, the signal posts and ground posts adjacent to each other can be made equal in height, so that the signal contacts can be connected to the cable units adjacent to each other. Alternatively, the terminal parts used as ground contacts can be shared, and combined with the improvement of assembly workability, contributes to the reduction of manufacturing costs.

  According to the invention of claim 6, when soldering the connecting portion of the connecting portion to the outer conductor of the coaxial cable, the molten solder can be stored in the through hole or groove formed in the connecting portion. Stable soldering is possible.

The width W in the parallel arrangement direction of the multipolar coaxial connector 1 can be narrowed to achieve miniaturization.

  Further, in the present embodiment, the connection portion 64 that is soldered to the outer conductor 42 of the coaxial cable 4 is provided at the front end portion of the coupling portion 61, and a plurality of through holes 64a are formed in the connection portion 64. When soldering to the conductor 42, the melted solder can be stored in the through hole 64a, and more stable soldering is possible.

  (Second Embodiment) FIGS. 12 to 14 show a second embodiment of the present invention. The multipolar coaxial connector 1A according to this embodiment includes the same components as those of the multipolar coaxial connector 1 according to the first embodiment. Therefore, common reference numerals are given to those similar components, and redundant description is omitted.

  12 is a perspective view of a multipolar coaxial connector in which the plug and the receptacle are separated, and FIG. 13 is an enlarged end view of the main part of the plug as viewed from the direction D in FIG. As shown in FIG. 12, the multipolar coaxial connector 1A of the present embodiment basically includes a plug 2 and a receptacle 3 as in the first embodiment, and includes a coaxial cable 4, a signal post 5, a ground post. 6 and a plurality of cable units CU each including an insulating block 7 are arranged in parallel, and this embodiment is mainly different from the first embodiment in that cable units adjacent to each other as shown in FIG. The CUs are arranged in a staggered manner with a predetermined amount of deviation in a direction perpendicular to the direction in which they are arranged in parallel (the vertical direction in this embodiment).

  Further, in the present embodiment, for the two cable units CU adjacent to each other, the ground posts 6 are arranged on the side away from the other cable unit CU in the perpendicular direction. That is, the two cable units CU adjacent to each other are in the posture inverted in the vertical direction. At this time, as shown in FIG. 12, the locking hole 22 for locking the locking claw 65 provided in the inverted cable unit CU is formed on the upper surface of the plug housing 21.

The width of the multi-pole coaxial connector 1A in the parallel arrangement direction can be narrowed to achieve downsizing.

  In addition, since the ground posts 6 of the cable units CU adjacent to each other are arranged apart from each other in the perpendicular direction so that they are not adjacent to each other in the parallel arrangement direction, it becomes easy to secure an insulating region on both sides in the parallel arrangement direction of the ground posts 6. The pitch of the cable unit CU can be set smaller.

  Furthermore, since the center of the tip portion T of the cable unit CU is set at the same height, the signal posts 5 and the ground posts 6 that are adjacent to each other can have the same height, and thus the cable units that are adjacent to each other. The terminal parts used as the signal posts 5 or the ground posts 6 can be shared for the CU, which contributes to the reduction of the manufacturing cost combined with the improvement of the assembly workability.

  That is, as shown in FIG. 12, the receptacle 3 is provided with two types of a tall contact CH and a short contact CL, but the parallel tall contacts CH are the signal contact 8 and the ground contact 9. Are alternately used as the ground contact 9 and the signal contact 8. Further, in this case, the signal terminal 81 and the ground terminal 91 are adjacent to each other two by two, and the two adjacent to each other are alternately arranged.

On the other hand, as shown in FIG. 15, the signal terminals 81 and the ground terminals 91 can be alternately arranged by using four types of contacts C1 to C4. If the signal-side terminal 81 and the ground-side terminal 91 are alternately arranged in this way, mutual interference of signals can be suppressed and noise resistance can be improved.

  In this case, it is composed of two types of contacts C2 and C4 that are tall and two types of contacts C1 and C3 that are short, but as shown in FIG. 16A, by punching and bending by press working. The contacts C1 and C3 are formed on the hoop 100, while the contacts C1 and C3 are similarly formed on the hoop 101 by pressing as shown in FIG. 16B, and the contacts C2 and C4 and the contacts C1 and C3 are formed. The work man-hours can be reduced by an assembling method in which the hoops 100 and 101 are separated after being assembled to the receptacle 3 while being connected to the hoops 100 and 101.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, the signal post 5, the ground post 6, the signal contact 8, the ground contact 9, and the insulating block 7 can be obtained as other shapes depending on the purpose without being limited to the embodiments, and the multipolar coaxial connector 1. , 1A plug 2 and receptacle 3 are not limited to their shape and structure, but may be any structure that can hold and protect the internal conductive member and be detachable from each other.
