Short-circuit protection connector

The invention provides a short-circuit protection connector. The short-circuit protection connector comprises a socket and a plug connected with the socket, wherein the socket comprises a shell, a short-circuit movable module and a jack assembly are arranged in the shell; the short-circuit movable module is composed of a contact pin, a shielding case and an upper base; the contact pin is installed in the upper base and then is poured and fixed; the upper base is fixed in the shielding case; the jack assembly is composed of a jack fitting piece, a middle base, a rubber pad and a lower base; the jack fitting piece is installed in the middle base the lower base; the rubber pad is arranged between the middle base and the lower base; the jack assembly is completely fixed in the shell through a step in the shell and a fixing nut. The short-circuit protection connector can achieve switching between the short-circuit function and the non-short-circuit function, and a short circuit and an open circuit between contacts are switched extremely conveniently. The locking mode of the plug and the socket is a threaded connection mode, the short-circuit function and the non-short-circuit function are controlled by a pushing rod, and control is more convenient and rapid.
