It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0016] As Figure 1-2 It is the structural schematic diagram of a wave spring for a connector anti-loosening structure in a preferred embodiment of the present utility model. In this embodiment, a wave spring for a connector anti-loosening structure includes a wave spring body 1 and a coaxial connecting spring body 2. The wave spring body 2 is composed of a plurality of wave spring coils 11, and the connecting spring body 2 is connected by a plurality of connecting spring coils 21. The wave spring coil 11 includes a plurality of wave peaks 13 and a plurality of wave valleys 12. The wave peaks 13 and wave valleys 12 on adjacent wave spring coils 11 are arranged in an alternating manner. A connecting spring coil 21 is arranged between the wave peak 13 and the wave valley 12, and the surfaces of the connecting spring coil 21 are respectively in contact with the surfaces of the wave peak 13 and the wave valley 12. By arranging the connecting spring body 2 in the wave spring body 1, during the use of the connector, under the influence of the pulling force, the risk of plastic deformation and elastic failure of the wave spring is effectively avoided.
