[0027] Reference Figure 1-6 This application proposes an embodiment of the brake pad wear detection wiring harness, which includes a friction block 10, a wiring harness plug 20, a connecting wire 30, and a fixing member 40. The wiring harness plug 20 has a positive terminal 21 and a negative terminal 22. The two ends of the connecting wire 30 are respectively connected to the positive terminal 21 and the negative terminal 22 of the plug. The friction block 10 has a receiving groove 11 on its side wall for accommodating the connecting wire 30. The fixing member 40 is installed on the friction block 10 and is used to embed the connecting wire 30 into the receiving groove 11.

[0028] When the wiring harness described in this application is in use, the friction block 10 is mounted on the brake pad with the receiving groove 11 facing the brake disc. The wiring harness plug 20 is connected to the vehicle system. The positive and negative terminals of the wiring harness plug 20 are connected and fed back to the vehicle system. During use, the brake pad rubs against the brake disc, causing its thickness to gradually decrease until the friction block 10 rubs against and wears off the brake disc. The thickness of both the friction block 10 and the brake pad will gradually decrease until, when the car brakes, the brake disc rubs against the connecting wire 30 in the receiving groove 11. As the brake pad continues to be used, the brake disc will wear off the connecting wire 30, and the positive and negative terminals of the wiring harness plug 20 will be disconnected. The vehicle system receives a signal that the positive and negative terminals of the wiring harness plug 20 are disconnected.

[0029] In this application, the connecting wire 30 is directly limited in the receiving groove 11 by the fixing member 40, which is convenient for installation. It does not require the conductive material to be embedded in the brake pad through an integrated molding process, thus avoiding the problem of conductive material failure caused by high temperature pressing molding.

[0030] Referring to the accompanying drawings, the friction block 10 has receiving grooves 11 on its two opposite sides, so that the friction block 10 can rub against the brake disc from both sides to detect the wear of the brake pads.

[0031] Based on the above, the friction block 10 has a first side surface on both sides of the receiving groove 11, and the friction block 10 also has a second side surface adjacent to the two first side surfaces. The second side surface has a mounting groove 12, and the mounting groove 12 is connected to the receiving groove 11. The connecting wire 30 is embedded in the mounting groove 12 and the receiving groove 11, so that the connecting wire 30 can be installed in the two receiving grooves 11.

[0032] Furthermore, the fixing member 40 is a U-shaped piece, the friction block 10 is provided with a U-shaped groove 13, and the U-shaped groove 13 is connected to the connecting groove but not connected to the receiving groove 11. The U-shaped piece is installed in the U-shaped groove 13 and presses the connecting line 30 into the receiving groove 11.

[0033] In this embodiment, the U-shaped piece presses the connecting wire 30 into the limiting groove 15, and the U-shaped piece presses the connecting wire 30 into the receiving groove 11 through elastic deformation, which is convenient to install and has a stable structure.

[0034] Preferably, the depth of the U-shaped groove 13 is greater than the thickness of the U-shaped piece.

[0035] Referring to the attached drawings, after the U-shaped piece is inserted into the U-shaped groove 13, there is still a certain space in the U-shaped groove 13. At this time, the friction block 10 can be directly inserted into the mounting position of the brake pad through the U-shaped groove 13, making installation more convenient.

[0036] Preferably, the U-shaped piece is a metal piece. Since the friction block 10 is directly inserted into the mounting position of the brake pad through the U-shaped groove 13 during installation, the temperature of the brake pad during use may reach 500°C. Therefore, the U-shaped piece in this application is preferably made of metal, which exhibits better heat resistance and thermal stability in high-temperature environments, and can quickly disperse and store heat, avoiding aging and cracking of the plastic elastic sheet in high-temperature environments.

[0037] See attached document Figure 1 As shown, there are two friction blocks 10, and the connecting line 30 is embedded in the receiving groove 11 on the two friction blocks 10. The two friction blocks 10 can be respectively installed on the two brake pads on both sides of the brake disc.

[0038] Preferably, a fixing sleeve 60 is also included. The friction block 10 is provided with a guide post 14. The guide post 14 is provided with a limiting groove 15 corresponding to the receiving groove 11. The fixing sleeve 60 is sleeved on the guide post 14 and limits the connecting line 30 in the limiting groove 15 to ensure that the connecting line 30 will not come out of the receiving groove 11.

[0039] Preferably, the friction block 10 is also provided with an L-shaped limiting member 16. One end of the limiting member 16 is connected to the friction block 10, and the other end has a gap with the friction block 10. The connecting line 30 passes through the gap to ensure that the connecting line 30 will not come out of the receiving groove 11.

[0040] Preferably, the connecting line 30 is provided with a protective sleeve 70 to protect the wire harness.

[0041] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
