When, in the housing 1 on one side 5A of the ground plate 5 facing the protruding surface of the terminal portion 3, and the through holes 7 provided in correspondence to each terminal unit 3 of the one, other than the one side 5A of the ground plate 5 on the other surface 5B is a region, together with the a pawl 6 for connecting and retaining the shielding 4B of the coaxial cable 4, passed through the terminal portion 3 of the one to the through hole 7, the other
Terminal portions 3 are connected to the ground plate 5, respectively .
Their respective signal line 4A of the coaxial cable 4 to the one terminal portion 3
It is configured to connect each. With this configuration, the above-described problem is solved.

[0013]

In other words, all the coaxial cables 4 are held by the other surface 5B of the ground plate 5, the respective shield braids 4B are connected, and the ground plate 5 is fixed to the housing 1. Fixed to 1.

The signal line of the coaxial cable 4 is connected to one terminal 3 passing through the through hole 7 on one surface 5A of the ground plate 5.
4A, and the other terminal 3 next to the ground plate 5
For example, the ground connection is easily made by short-circuit soldering with the terminal portion 3 penetrating the same through-hole 7, press-fitting or soldering of a known connection technology, and the corresponding coaxial through the ground plate 5. It is conducted to the shield braid 4B of the cable 4.

Therefore, it is not necessary to connect to the terminal portion 3 by bending the tongue piece 10A as in the related art, and the contacts 2-1 and 10-2 are not required.
The arrangement pitches P1 and P2 of 2-2 can be narrowed, and a connector for high-density mounting can be obtained.
