Thin socket

This creation is about a thin type of socket, especially for earphones, and a thin, light and simple socket.

Currently used sockets are, for example, the improved sockets disclosed in the Chinese Patent Publication No. M445282 (Application No. 101212034). As shown in FIG. 7 and FIG. 8, the socket 500 includes a body 510, a plurality of contact pieces 501, 502, 503, and 504, a detecting switch 506, and a positioning member 507. The base 510 is an insulating, slightly rectangular box-shaped body having a circular insertion hole 511 in the longitudinal direction thereof. As shown in FIG. 7, an opening 512 is provided at one end of the insertion hole 511. The insertion hole 511 has a diameter slightly larger than the diameter of the plug 9. The two sides of the base 510 are provided with a plurality of fixing grooves 5101, 5102, 5103, and 5104 parallel to the two sides, such as As shown in FIG. 8 and FIG. 9, the plurality of contact pieces 501, 502, 503, and 504 are disposed, and the fixing grooves 5101, 5102, 5103, and 5104 are in communication with the insertion hole 511; and the base 510 corresponds to the The inner side of the other end of the opening 512 is provided with a fixing groove 5104 on one side. As shown in FIG. 9, the device contacts the piece 504, and the other side is respectively provided with a set of external fixing grooves 51061 and an inner fixing groove 51062, respectively. The fixed contact portion 5061 and the movable contact portion 5062 of the detecting switch 506 are connected to the insertion hole 511; a horizontal fixing is disposed on the top surface 518 of the base 510. The groove 5107 is configured to connect the positioning member 507, and the fixing groove 5107 communicates with the insertion hole 511 as shown in FIG.

When the plug 9, as shown in FIG. 5, is fully inserted into the insertion hole 511, as shown in FIG. 10, the first contact ring 951, the second contact ring 952, the third contact ring 953, and the tip end portion of the plug 9 are as shown in FIG. The contact pieces 501, 502, 503, and 504 exposed in the insertion hole 511 are elastically abutted and electrically connected. The front end portion 91 of the plug 9 is also elastically abutted against the detecting switch 506. The movable contact portion 5062 pushes the movable contact portion 5062 to elastically abut against the fixed contact portion 5061, thereby generating electrical conduction, thereby converting switches of other electronic devices connected to the improved socket 500; The tip end portion 91 of the plug 9 and the positioning member 507 can not only easily detach the plug 9, but also reduce the elastic pressure of the plug to the contact member, thereby increasing the service life of the contact member.
