DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a connector according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG.
FIG. 1 is a side view showing a configuration of a clip terminal forming a part of a connector according to an embodiment of the present invention. As shown in FIG. 1, the clip terminal provided in the connector of the present embodiment includes:
The wave-shaped terminal portion 12 is provided at an end of the substrate 10. In the present embodiment, a case where a metal plate is formed into a corrugated shape is described as an example of the terminal portion 12, but a linear shape may be used as the terminal portion 12 and the terminal portion 12 may be formed into a waveform.

FIG. 2 shows a state where a clip terminal forming a part of the connector according to the embodiment of the present invention shown in FIG. 1 is inserted into a socket forming a part of the connector according to the embodiment of the present invention. FIG. Here, a socket forming a part of the connector according to the embodiment of the present invention will be described. The socket forming a part of the connector according to the embodiment of the present invention has the same configuration as the socket shown in FIG.

That is, in the socket 20 which forms a part of the connector according to the embodiment of the present invention, two metal plates 22 and 24 made of metal are provided at the insertion portion into which the clip terminal is inserted. The metal plates 22 and 24 have substantially the same shape, and are symmetrical with respect to the center axis of the insertion portion, and contact portions 22b of the metal plate 22 and contact portions 24 of the metal plate 24.
