[0024] In the embodiment of the present application, the wiring harness body 301 is passed through the center holes of the fixed ring 402 and the first movable ring 406, and the control block 423 is rotated by the Allen wrench. The meshing action of the worm 422 and the annular gear 461 drives the first movable ring 406 and the second movable ring 408 to rotate, and the cylindrical block 409 drives the square frame 410 to slide on the outside of the movable rod 451, and then drives the fixed arm 405 to rotate toward the center of the first movable ring 406 with the fixed shaft 404 as the axis, so that the clamping wheel 454 squeezes the outside of the wiring harness body 301, thereby achieving the fixing effect of the wiring harness body 301. Due to the self-locking effect of the worm 422 and the annular gear 461, the first movable ring 406 is prevented from rotating due to vibration, so that the clamping wheel 454 always maintains a good clamping and fixing effect on the wiring harness body 301, which can avoid accidental pulling of the connector body 3 and the wiring harness body 301, and avoid the problem of poor contact;

[0025] By rotating the threaded column 202 through the handle block 203, the threaded column 202 drives the lifting plate 204 to move downward under the action of the thread thrust, so that the connector body 3 can be pressed and fixed. The rubber pad 205 can increase the contact area and friction with the top of the connector body 3, and can play a role in buffering protection, avoiding the problem of noise caused by collision between the connector body 3 and the installation part when the car vibrates during driving.

[0027] The fixed arm 405 is located between the first movable ring 406 and the second movable ring 408 . Controlling the rotation of the first movable ring 406 can drive the square frame 410 to slide along the outer side of the movable rod 451 , thereby causing the fixed arm 405 to rotate around the fixed axis 404 .

[0032] Among them, the connector fixing assembly 2 includes a fixing frame 201 fixedly connected to the top of the mounting plate 1, a threaded column 202 is sleeved on the middle thread of the top of the fixing frame 201, a handle block 203 is fixedly connected to the top of the threaded column 202, a lifting plate 204 is movably connected to the bottom of the threaded column 202, a rubber pad 205 is fixedly connected to the bottom of the lifting plate 204, a positioning tube 206 is fixedly connected to the top of the inner wall of the fixing frame 201, a positioning rod 207 is movably sleeved on the inner side of the positioning tube 206, and the bottom of the positioning rod 207 is fixedly connected to the top of the lifting plate 204.

[0033] The positioning tube 206 and the positioning rod 207 can play a role in positioning the lifting plate 204, so that when the threaded column 202 rotates and rises and falls, it can drive the lifting plate 204 to move up and down.

[0034] The working principle and use process of this utility model:

[0035] The harness body 301 is passed through the center holes of the fixed ring 402 and the first movable ring 406, and the control block 423 is rotated with the Allen wrench.

Due to the self-locking effect of the worm 422 and the annular gear 461, the first movable ring 406 is prevented from rotating due to vibration, so that the clamping wheel 454 always maintains a good clamping and fixing effect on the harness body 301, which can avoid accidental pulling of the connector body 3 and the harness body 301, and avoid the problem of poor contact.

[0036] By rotating the threaded column 202 through the handle block 203, the threaded column 202 drives the lifting plate 204 to move downward under the action of the threaded thrust, so that the connector body 3 can be pressed and fixed. The rubber pad 205 can increase the contact area and friction with the top of the connector body 3, and can play a role in buffering protection, thereby avoiding the problem of noise caused by collision between the connector body 3 and the installation point when the car vibrates during driving.
