The core wires 4 face each other so as to overlap the second connecting piece 60 of the second terminal 58. The overlapping opposing second connecting piece 60 and the core wire 4 are soldered.

(7) Next, the side wall portion 50 and the side wall of the second conductive cell 45 can cover the top of the coaxial cable assembly 1 from the front direction of the housing, that is, the direction opposite to the direction in which the coaxial cable 2 is placed (right in FIG. 1). The coupling portion 49 is coupled to the transverse side of the housing and inserted into the outer circumference, and the grip portion 46 of the second conductive cell 45 is coupled to the second conductive cell coupling groove 20 of the housing, so that the protruding piece 48 of the side wall coupling portion 49 (see Fig. 17). The second conductive cell 45 is fixed to the outer circumferential side of the housing 11 by coupling to the coupling part not shown in the drawing of the housing 11. At the time of the fixing, tongues 47a, 47b, and 47c of the second conductive cell 45 shown in FIGS. 1 and 3 press the ground plate 3 of the coaxial cable assembly 1 on the upper end to elastically connect, and electrically connect to the ground plate 3. The outer conductor 6 of the coaxial cable 2 is electrically connected to the second conductive cell 45.

Then, the ground plate 3 of the coaxial cable assembly 1 of the upper end electrically connected to the first conductive cell 35 is pressed and electrically connected to the tongue piece 47a (, 47b, 47c) of the second conductive cell 45, and the lower part of the ground plate 3 The electrical connection is obtained by pressing the cable placing portion 41 of the first conductive cell 35 located on the side.

Thus, the ground plate 3 of the coaxial cable assembly 1 of the upper end electrically connected to the first conductive cell 35 and the ground plate 3 of the coaxial cable assembly 1 of the lower end electrically connected to the second conductive cell 45 are electrically connected. This makes it possible to electrically connect both ground plates 3 even when the upper and lower coaxial cables are arranged in physically displaced positions at the time of assembly.

The coaxial cable connector thus assembled can be engaged with the other connector. That is, the contact portion 73 is connected to the first contact piece 56 by engaging the first, second, and third coupling protrusions 66, 67, and 68 of the counterpart connector 63 with the first, second, and third coupling recesses 21, 22, and 23. In a state of contacting, the contact portion 79 is in contact with the second contact piece 59.

Although the embodiment has been described as assembling two stages of coaxial cable assemblies, the present invention is not limited thereto. For example, three stages may be used. .

In the multi-pole coaxial cable connector of the present invention, for example, thirty micro coaxial cables are bundled to form an assembly, and the assemblies are arranged in a state where there is an up-and-down step and deviate from each other in the horizontal direction, and each ground plate is placed through the cell. By electrically connecting, a plurality of micro coaxial cables, for example, 60 coaxial cables, can be easily assembled into 30 assemblies, and a multi-pole coaxial cable connector can be provided that can be reduced in size.
