[0002] The electronic brake signal line is an important component in the car, used to transmit the signal of the brake system. It connects the circuit between the brake pedal switch and the brake control unit. When the driver steps on the brake pedal, the brake pedal switch sends a signal to the brake control unit to inform it that it needs to brake. The brake control unit then transmits the signal to the brake actuator through the electronic brake signal line to trigger the brake system to work. The electronic brake signal line is usually composed of wires and connectors. The wires are responsible for transmitting signals, and the connectors are used to connect the wires and various brake system components. Compared with the traditional mechanical brake system, this electronic brake system has a faster response speed and more precise brake force control, which improves the safety and comfort of driving. The shell on the traditional electronic brake signal extension line is directly formed with wires, and the waterproof level of the contact surface between the shell and the outlet of the brake controller box does not meet the waterproof level of the actual use environment.
[0003] The electronic brake signal extension cable is a device used to extend the brake signal line in the electronic brake system. It can help extend the length of the brake signal line to better meet the needs of a specific vehicle or installation location. At present, the shell of the traditional electronic brake signal extension cable is directly formed with wires, and the waterproof level of the contact surface between the shell and the outlet of the brake controller box does not meet the waterproof level of the actual use environment, and the waterproof performance does not meet the use requirements.

[0023] The utility model embodiment discloses an electronic brake signal extension line, such as Figure 1-4 As shown, it includes a shell 1 and a branch line card 2 arranged in the shell 1. The shell 1 is made of PA66+30% GF injection molding, and the line card is made of pp injection molding. The shell 1 is hollow, and a slot 11 is provided on one side surface of the shell 1. The branch line card 2 is plugged into the slot 11, and the branch line card is plugged into the slot 11 to be assembled with the shell 1. In addition, a plurality of wires 21 are arranged on the branch line card 2, and the branch line card 2 is integrally injection molded onto the wires 21. At the same time, a protrusion 12 is integrally molded on the outer side of the shell 1, and the protrusion 12 is through-set. One end of the wire 21 passes through the protrusion 12, and the other end of the wire 21 passes through the slot 11.
[0024] At the same time, a sealing layer 3 is poured into the shell 1, and the sealing layer 3 is coated on the wire 21 and the branch line card 2. The sealing layer 3 is a black sealing resin, and the sealing layer 3 can be poured into the shell 1 through the protrusion 12. At the same time, a card slot 22 is opened on the side of the branch line card 2, and the sealing layer 3 is embedded in the card slot 22, which can improve the firmness between the branch line card 2 and the shell 1, so that the branch line card 2 is not easy to be separated from the shell 1. In addition, the inner wall of the slot 11 is integrally formed with a convex edge 111, and the side wall of the branch line card 2 is integrally formed with a limiting protrusion 23. When the branch line card 2 is inserted into the slot 11, the limiting protrusion 23 abuts against the convex edge 111. When the operator inserts the branch line card 2 into the slot 11, the limiting protrusion 23 abuts against the convex edge 111, which can play a positioning role and prevent the branch line card 2 from being excessively inserted into the shell 1.
[0025] In addition, a waterproof rubber pad 4 is provided on the outer side of the housing 1, and the waterproof rubber pad 4 is sleeved on the raised portion 12. After the housing 1 is installed on the outlet of the brake controller, the waterproof rubber pad 4 can improve the sealing performance between the housing 1 and the outlet, and improve the waterproof performance. At the same time, a receiving groove 13 is provided on the outer side of the housing 1, and the waterproof rubber pad 4 is embedded in the receiving groove 13. The receiving groove 13 can better install the waterproof rubber pad 4 on the housing 1. At the same time, a convex ring 41 is integrally formed on the surface of the waterproof rubber pad 4 that is away from the housing 1. The convex ring 41 is arranged around the raised portion 12, and the convex ring 41 can improve the waterproof performance of the waterproof rubber pad 4.
[0026] In addition, through holes 14 are provided at the four corners of the housing 1, and openings 42 are provided at the four corners of the waterproof rubber pad 4, and the openings 42 are aligned with the through holes 14. The through holes 14 of the housing 1 can facilitate the installation of the housing 1 on the outlet of the brake controller. At the same time, a convex ring 43 is integrally formed at the opening 42 of the waterproof rubber pad 4, and a convex edge 111 is located on the surface of the waterproof rubber pad 4 away from the housing 1. The convex ring 43 is arranged along the circumferential direction of the opening 42, and the convex edge 111 can improve the sealing of the through hole 14 of the housing 1 and improve the waterproof performance.
[0027] The implementation principle of the electronic brake signal extension line of the utility model embodiment is as follows: the operator inserts the branch line card 2 into the slot 11, and then pours resin glue into the shell 1 from the raised portion 12 of the shell 1. After the resin glue solidifies, a sealing glue layer 3 is formed to fix the branch line card 2 in the shell 1, and the sealing glue layer 3 has good waterproof performance and can prevent water from penetrating into the shell 1. At the same time, after the shell 1 is installed on the outlet of the brake controller box, the waterproof rubber pad 4 can play a waterproof role, thereby improving the overall waterproof level. In addition, this product solves the point waterproof problem between the two separate assembly parts, avoids repeated gluing and sealing of the extension line shell 1 and the outlet of the brake controller, and facilitates maintenance and disassembly.
