[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Reference Figures 1 to 5 As shown, the utility model provides a sealed elastic buckle type anti-rotation wiring harness structure, comprising: a wiring harness 1, a wire outlet cover 2, and an elastic plug plate 3.

[0022] A sheath insert assembly 12 for connecting to a motor is installed at one end of the wiring harness 1 .
