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, and the assembly 1 is a sleeve or a flat plate with a through hole.

The fixing member 2 is a bolt disposed in 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 At least one limiting groove 23 is provided on the outer periphery of the first fixing portion 21.

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

When used, it can be used as a locking mechanism for various electrical connectors, and the combination The component 1 is connected to the electrical connector, and the terminal-related plug (not shown) is inserted through the through hole 12, and the elastic component 3 is compressed during the insertion, so that the elastic component 3 provides a terminal or a connector It forms circuit conduction, and provides elasticity or provides shockproof force; and since one end of the elastic element 3 can be firmly set in the limiting groove 23, when in actual use, it can avoid repeated contact of the terminal or the connector. The elastic element 3 is separated from the fixing element 2 so that the elastic element 3 and the fixing element 2 achieve a stable combination.
