The locating piece matched with the sealing part is arranged on the plug bush body, so that the connection between the clamp spring and the plug bush body is more compact, and the clamp spring and the plug bush body are convenient to assemble.

In particular, bending guide parts are respectively arranged on the two contact pieces. The bending guide part can play a role in guiding the plug, so that the plug bush body and the plug are convenient to plug.

Particularly, the plug bush body on be provided with the line ball portion that cooperatees with binding post, line ball portion alternate in binding post's terminal frame, line ball portion on be provided with binding post's binding screw matched with constant head tank. The locating groove is arranged on the line pressing part of the plug bush body, so that the wiring screw can be guaranteed to be capable of pressing the lead on the line pressing part, wiring is more convenient and firm.

The utility model also provides a socket, which comprises the plug bush assembly. The socket with the plug bush component adopting the structural design can effectively prolong the service life of the socket.

Particularly, the socket also comprises a base, a protective door assembly, a gland and a face cover, wherein the plug bush assembly is arranged in the base, clamping grooves are respectively formed in the positions, corresponding to the plug bush assembly, of the plug bush body in the base, the plug bush body is clamped in the clamping grooves, and the plug bush body is in limiting fit with the base. The plug bush body is assembled with the base in a limit fit mode, so that the plug bush assembly and the base are convenient to assemble, and the assembling efficiency of the socket is improved.
