<p>PROBLEM TO BE SOLVED: To secure the safety in the connecting time, by making in the locking condition by displacing a projection provided at the position on the way of the slide stroke of a sleeve, and a cutting provided at the rear end of the sleeve, at a specific angle automatically. SOLUTION: When a socket 1 and a plug 20 are connected, a sleeve 3 is rotated a specific angle against the twisting energizing force of a coil form sleeve spring 5, so as to make the position of a cutting 13 coinside to the position of a projection 12, the plug 20 is inserted to the socket 1 at the condition pulling back the sleeve 3 sufficiently to the rear end of a socket main body 2, and then the sleeve 3 is removed, and as a result, a locking ball 11 and the engaging groove 21a of a plug main body 21 are engaged so as to connect and hold the socket 1 and the plug 20. In this case, when the sleeve 3 is slided to the front end side of the socket main body 2, the sleeve 3 is rotated by the energizing force by the twisting of the spring 5, the positions of the projection 12 and the cutting 13 are restored to the condition displacing a specific angle, and the sleeve 3 is locked, and the socket 1 and the plug 20 are never separated.</p> |
