The electric signal connection socket 10 has a case structure in which a hollow wall 12 is defined by a rigid wall 11, and a groove or a track 13 is formed on an inner surface of the rigid wall 11 to guide the entry of the electric signal plug. And an action of restricting lateral movement at the time of insertion. A pair of elastic suspension arms 14 are installed at predetermined positions symmetrical to each other near the entrance in the hollow chamber 12. In the illustrated embodiment of the invention, the resilient suspension arms 14 are formed at two corresponding locations near the entrance on the inner surface of the cavity 12, extend in the direction of insertion of the plug 20, and are subjected to external forces. It has a free end 15 that can swing.

  In effect, the surface of the free ends 15 of these resilient suspension arms 15 facing the cavity 12 is further inwardly provided at a relatively narrow predetermined position adjacent to a pair of mutually adjacent but facing the flat entrance. An inclined narrow convex portion 16 and an outwardly inclined wide convex portion 17 are provided at a predetermined wide position, and a stopper portion 161 facing the entrance is formed in the narrow convex portion 16. As shown in FIGS. 1 and 2, a connecting or continuous spine 18 is formed at the most protruding point of the narrow convex portion 16 and the wide convex portion 17, and the narrow convex portion 16 and the wide convex portion 17 are formed in the hollow chamber. 12, the wide convex portion 17 is formed at a wide outside position in the plug insertion direction with respect to the narrow convex portion 16, and the wide convex portion 16 has an entrance.
