The connector socket 20 includes: a socket housing 21 having the above-mentioned fitting recess 21a into which the connector plug 10 connected to the two insulated wires 130 is inserted from the front; When the pair of connection contacts 23 of the contact contact portion 23a protruding into the fitting recess 21a, as shown in FIG. As a result, the contact plate portions 3 of the crimp contacts 2 exposed to both side surfaces of the plug housing 11 come into elastic contact with the contact contact portions 23a, respectively.

As shown in FIG. 4 , the socket housing 21 is formed into a U-shape by integrally forming a connecting frame portion 25 and a pair of arm portions 26, 26 protruding forward from both sides of the connecting frame portion 25 by insulating synthetic resin. The U-shaped frame body 22 and the metal cover 24 covering the planar surface of the U-shaped frame body 22 are constituted, and by the surface of the circuit board 120 on which the connector receptacle 20 is installed, the U-shaped frame body 22 and the metal cover 24, a front-facing Open fitting recess 21a.
