Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-4, the invention provides a national standard direct current socket capable of rapidly replacing terminals, comprising a socket body 1, socket terminals 2 and a dismounting tool 3, wherein the socket terminals 2 are fixedly arranged inside the socket body 1, the socket terminals 2 comprise a rear end 4, a front end 5 and two end caps 6, the front end 5 is a part in contact with an electrified part of a charging gun product and can be rapidly dismounted and replaced, the rear end 4 is a wire pressing cup part and is fixedly arranged inside the socket body 1, the front end 5 is inserted and connected on one side of the rear end 4, the two end caps 6 are arranged on the periphery of one end of the front end 5, the tops of the opposite sides of the two end caps 6 are respectively provided with a clamping groove 7, the bottoms of the opposite sides of the two end caps 6 are respectively fixedly connected with a clamping block 8, the two clamping blocks 8 are respectively clamped and connected with the two clamping grooves 7, so as to fix the two end caps 6 together, the side surfaces of the two end caps 6 are respectively provided with an assembling groove 9, an assembling block 10 is inserted and connected in the assembling groove 9, and a disassembling tool 3 is fixedly connected to one side of the assembling block 10.

Preferably, the spiral limiting outer grooves 11 are formed in one side, away from each other, of the two end caps 6, the spiral limiting inner grooves 12 are formed in the inner wall of the rear end 4, the spiral limiting inner grooves 12 correspond to the spiral limiting outer grooves 11, and therefore the end caps 6 with the front ends 5 can be limited in the rear end 4.
