The wiring harness can be fixed by the abutment plate 703, and wiring harnesses of different models and sizes can be fixed, thereby increasing practicality.

[0033] In the utility model, the working steps of the device are as follows:

[0034] The first step is to connect the female connector 2 and the sub-connector 3, and then push the protective cover 4 toward the female connector 2 so that a part of the protective cover 4 covers the female connector 2. At the same time, the protective cover 4 will drive the clamping block 502 to move, which can drive the clamping block 502 to enter the inside of the clamping groove 507 for clamping, fix the protective cover 4, and form an additional protective mechanism to prevent the connector from being pulled by the outside or falling off due to long-term work. When the connection between the female connector 2 and the sub-connector 3 needs to be disconnected, the sliding bar 503 is pulled upward to drive the clamping block 502 to move upward, and at the same time, the clamping spring 504 is compressed, and finally the distance between the clamping block 502 and the clamping groove 507 is increased to disconnect the clamping relationship. Then, the protective cover 4 can be pushed onto the sub-connector 3 again, and the connection between the female connector 2 and the sub-connector 3 can be disconnected, which is convenient for personnel to operate and understand. When the clamping block 502 moves, it can drive the slider 506 to slide in the slide groove 505, so that the movement of the clamping block 502 is more stable.

[0035] The second step: after the female connector 2 and the sub-connector 3 are connected, the female connector 2 and the sub-connector 3 are respectively placed in the interior of the fixing plate 701, and the stud 702 is rotated to drive the abutment plate 703 to descend and fix it, and then the mounting seat 9 is fixed at the installation position. When the joint is subjected to external vibration, the force brought by the vibration drives the female connector 2 and the sub-connector 3 to swing up and down, thereby driving the fixing plate 701 to move up and down, which can drive the movable rod 802 and the first spring 804 to move downward, and pull the first spring 804 to deform it. The deformation of the first spring 804 has a buffering effect and preliminarily absorbs the force driven by the vibration. When the first spring 804 moves downward, the two ends squeeze the buffer plate 805, so that the second spring 806 is compressed to absorb the impact force. The first spring 804 and the second spring 806 can achieve a double buffering and shock absorption effect, thereby improving stability, avoiding large displacement of the joint and hitting the installation position, and being able to adapt to a continuous vibration environment.
