The wheel speed sensor is a sensor used to measure the speed of the car's wheels.

The above problem still exists. When using the wheel speed sensor, the above device connects the epb-end injection-molded wiring harness and the wheel speed injection-molded wiring harness by setting a branching device, thereby integrating the wheel speed sensor with the EPB wiring harness. When the wheel speed sensor is in use, it is necessary to insert the plug into the port, which is not convenient for sealing the plug position, and thus easily causes water to enter the plug and the port, thereby affecting the normal use of the wheel speed sensor. The waterproof effect is poor, and after connecting the epb-end injection-molded wiring harness and the wheel speed injection-molded wiring harness to the branching device, it is not convenient to fix the epb-end injection-molded wiring harness and the wheel speed injection-molded wiring harness again, and thus when pulled by external force, it is easy to cause the epb-end injection-molded wiring harness and the wheel speed injection-molded wiring harness to separate from the branching device, thereby causing damage.
