As shown in the figure, the locking mechanism of an electrical connector of the present invention comprises an assembly 1, a fixing member 2 and an elastic member 3.

The assembly 1 includes an accommodating space 11 and one end of the assembly 1 has a through hole 12 communicating with the accommodating space 11. The assembly 1 is a sleeve or a flat plate having perforations.

The fixing member 2 is disposed on the accommodating space 11 . The fixing member 2 includes a first fixing portion 21 and a second fixing portion 22 . The first fixing portion 21 is disposed at one end of the second fixing portion 22 . And at least one limiting slot 23 is disposed on the outer circumference of the first fixing portion 21 .

The elastic member 3 is disposed in the accommodating space 1 , and at least one elastic body at one end of the elastic member 3 is disposed in the limiting slot 23 , and the elastic member 3 is a coil spring, wherein the depth of the limiting slot 23 is It is greater than or equal to the wire diameter of the elastic member 3.

When used, it can be used as a locking mechanism for various electrical connectors, and the combination The component 1 is coupled to the electrical connector, and the through-hole 12 is inserted into the terminal-related connector (not shown), and the elastic component 3 is compressed during the insertion, so that the elastic component 3 provides the terminal or the connector. Forming a circuit to conduct, and providing an elastic force or providing a shockproof force; and since one end of the elastic member 3 can be stably disposed in the limiting slot 23, when it is actually used, the reverse of the terminal or the connector can be avoided. The elastic member 3 is separated from the fixing member 2, so that the elastic member 3 and the fixing member 2 can achieve a stable bonding effect.

In an embodiment of the present invention, the accommodating space 11 has a first accommodating area 111 and a second accommodating area 112. The first fixing part 21 is disposed in the first accommodating area 111. The second fixing portion 21 is disposed in the second receiving area 112 . The outer peripheral ring of the first fixing portion 21 is provided with two opposite convex rings 231 and 232.
