When bent into a substantially U-shape along the forming direction of the coaxial cables 16, the center conductors 40 b to 44 b of the coaxial cables 40 to 44 correspond to the plurality of cable guide grooves 1 as shown in FIG.
It is bent and arranged in a substantially U-shape along 2-16.

Thereafter, the cable holder 10 provided with the above-described coaxial cables 40 to 44 can be attached to the socket 25 via the holder cover 17 as shown in FIG. As shown in FIG. 11, the cable holder 10 provided with the cable 44 can be directly mounted on the plug 35, and then the plug 35 with the cable holder 10 can be mounted on the socket 25.

In the case of a connector in which the coaxial cables 40 to 44 are mounted on the cable holder 10, it is necessary to ground each outer conductor of each coaxial cable to a common ground. As shown in the connector 60 of FIG. 15, the outer conductor of each of the coaxial cables 40 to 44 is short-circuited to the lower surface of the conductor cable arrangement member 50.
A ground plate 70 is disposed in contact with the plug 35, and a part 70a of the ground plate 70 is exposed to the side of the plug 35 as shown in FIG. When the plug 35 and the socket 25 are fitted with each other, the part 70a is brought into contact with a terminal 71 disposed on the side of the socket 25, and a part 71
a is exposed to the outside of the socket 25, and a part 71a of the terminal 71 may be used as a ground terminal.

In FIG. 15, reference numeral 10a denotes a latch for positioning and supporting the cable holder 10 in the plug 35.

[0039]

As described above, in the connector according to the present invention, a cable holder having a plurality of cable guide grooves bent and formed in a substantially U-shape at a predetermined pitch is provided along each cable guide groove. Since the cable conductors are arranged so that each cable conductor is bent in a U-shape, each cable conductor bent in the U-shape can be used as a plug of a connector. It is not necessary to perform the connection work by crimping or soldering each of the cable conductor and each contact, and collective connection is possible. Therefore, the connection work of the connector can be extremely easily performed, and incorrect wiring can be prevented.

Further, in the connector according to the present invention, unlike the conventional connector, there is no crimping portion or soldering portion for connecting each cable conductor and each contact, so that the pitch between each cable conductor corresponding to the contact is further narrowed. The pitch can be reduced, so that the connector can be further reduced in size.
