The stopper 2 has a right stopper 21 and a left stopper 22. The right stopper 21 is integrally formed in a step-like manner, has a slope 211 recessed at the front edge of the upper step, a rectangular hole 212 formed at a predetermined position on the lower surface, and a projection 213 at the rear edge of the lower step. Are formed. The left stopper 22 is integrally formed in a frame base shape, the front side streak 221 is formed to have a concave slope 222 at the outer corner, and the rear side streak 223 is formed to have a lower recessed shape, and the inside streak is formed. 224 are formed, and a protrusion 225 is formed on the rear side.

The spring 3 is formed by bending a long metal sheet, a cylindrical portion 31 is formed by bending a rear end portion of the long sheet, and a hook portion 32 is formed by bending a hook portion 32 at a front stage. Further, the spring 3 is formed so as to return automatically when the right stopper 21 and the left stopper 22 are moved. The support base 4 is an insulator cover that covers the upper end of the socket 50. The support base 4 is formed in a zigzag shape, the outer shape is not limited to a fixed shape, and is formed corresponding to the shape of the socket 50, and a predetermined position on the surface. Is formed with a protruding frame 41. The projecting frame 41 has two holes 42 corresponding to the conductive plate of the socket 50 on the inner bottom surface, and projecting columns 43 to which the springs 3 are attached are formed on both inner sides.

A frame-shaped left stopper 22 penetrates the bottom of the upper stage of the right stopper 21, and the right stopper 21 closes the hollow portion of the left stopper 22 so that the rear end of the left stopper 22 has a horizontal line 223 and a horizontal line 224. The left end of the left stopper 22 is connected to the hole 212 of the right stopper 21 by being overlapped. As shown in FIG. 3, the right stopper 21 and the left stopper 22 correspond to each other and are slidably combined, and are disposed inside the protruding frame 41 of the support base 4 so as to cover the hole 42 at the bottom of the protruding frame 41. I have. The cylindrical portion 31 of the spring 3 is attached to each of the two projecting columns 43 of the projecting frame 41 of the support base 4. The hooks 32 at the front ends of the two springs 3 extend to both inner sides of the projecting frame 41 and are connected to the projections 213 and 225 at the rear ends of the right stopper 21 and the left stopper 22, respectively. As shown in FIG. 4, the right stopper 21 and the left stopper 22 are arranged so as to maintain the closed state by the elastic force of the spring 3. The cover 1 is covered on the upper part of the projection 41 of the support 4 and the plug insertion leg is inserted.

As shown in FIG. 5, when the two insertion legs 601 of the general plug 60 are simultaneously inserted into the insertion holes 11 of the cover 1, the insertion legs 601 cause the left stopper 22 and the slopes 222 of the right stopper 21 to move. The slope 211 is pressed. When the slope 222 and the slope 211 are pressed by the insertion legs 601, the left stopper 22 and the right stopper 21 are pushed into the inside, the hollow portion of the left stopper 22 and the hole 212 of the right stopper 21 are separated, and the two insertions are performed.
