Description

Technical Field

[0001] This utility model relates to the field of automotive caliper wiring harness technology, and in particular to a fixing structure for injection-molded rubber parts of automotive caliper wiring harnesses. Background Technology

[0002] The automotive caliper wiring harness is the electrical connection harness related to the brake caliper in the automotive braking system. It is mainly used to transmit electrical signals to realize the control, monitoring and information feedback of the caliper-related electronic components. It is an important component of modern automotive electronic braking systems (such as electronic parking brake EPB, brake assist system, etc.).

[0003] When using automotive caliper wiring harnesses, external rubber components are required to securely install the harnesses at designated workstations. However, existing rubber components present certain inconveniences during use.

[0004] The rubber components used in current automotive caliper wiring harnesses are designed separately from the wiring harness. During assembly, the rubber components must be individually threaded onto the caliper wiring harness before the entire assembly is installed. However, this design has significant drawbacks in actual use: Firstly, the separate design results in poor stability between the rubber components and the wiring harness, and vibrations during vehicle operation can easily cause the rubber components to shift or loosen. Secondly, it is difficult to ensure a complete fit between the rubber components and the wiring harness, as well as the joints of the rubber components themselves, during assembly, which greatly reduces the overall sealing performance and waterproofing. External moisture, dust, and other impurities can easily penetrate through the gaps, thereby affecting the insulation performance and service life of the wiring harness, and may even pose a potential threat to the electrical control safety of the braking system.

[0005] Therefore, we propose a fixing structure for injection-molded rubber parts of automotive caliper wiring harnesses. Utility Model Content

[0006] In addressing the technical problems of existing technologies, such as the poor stability of the fixed rubber parts and wiring harness due to the split design, which makes the rubber parts prone to displacement or loosening due to vibrations during vehicle operation; and the difficulty in ensuring complete fit between the rubber parts and wiring harness, as well as the joints of the rubber parts themselves, during assembly, which significantly reduces the overall sealing performance and waterproofing, allowing external moisture, dust, and other impurities to easily penetrate through the gaps, thereby affecting the insulation performance and service life of the wiring harness, and even potentially posing a threat to the electrical control safety of the braking system, this utility model provides a fixing structure for injection-molded rubber parts of automotive caliper wiring harnesses.

[0007] The technical solution adopted by this utility model is: a fixing structure for injection-molded rubber parts of automotive caliper wiring harnesses, including a rubber part body, a caliper wiring harness body and a positioning seat. A guide cylinder is provided on the outer surface of one end of the rubber part body, and a positioning end ring is provided on the outer surface of the other end of the rubber part body. An insertion block is provided in the middle of the positioning seat. A flexible metal strip is fixedly installed on the upper outer surface of the insertion block, and a guide ring is fixedly installed on the outer surface of one end of the flexible metal strip. A slot is provided on the outer surface of the front end of the positioning seat, and a locking block is provided on the outer surface of the front end of the insertion block. An internal groove is provided inside the insertion block, and a connecting spring is provided between the internal groove and the locking block.

[0008] Furthermore, the rubber parts are all integrally formed with the guide cylinder and the positioning end ring.

[0009] Furthermore, the caliper harness body passes through the guide cylinder and the rubber component body, and the lower outer surface of the positioning seat is fixedly connected to one outer surface of the positioning end ring.

[0010] Furthermore, the positioning seat and the slot are integrally formed, and the insert block is fitted and connected to the positioning seat.

[0011] Furthermore, the insert block and the built-in slot are integrally formed, and the built-in slot is movably connected to the locking block through the connecting spring.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, the rubber body, guide tube, and positioning end ring are integrally injection molded structures and are directly injection molded onto the caliper harness body. This ensures stability between the caliper harness body and the caliper harness body during use. It can pass through the vehicle body mounting position and be installed seamlessly into the vehicle body, simplifying the installation process and improving the sealing and waterproofing during use.

[0014] 2. In this utility model, the insert block can be inserted into the positioning seat during use. When fixing and connecting, the locking block can be pressed first to retract into the built-in groove and compress the connecting spring. After the insert block is inserted, the locking block and the groove are in a horizontal state. At this time, the connecting spring can spring the locking block into the groove to limit and fix the insert block. Then, the caliper harness body can be passed through the guide ring, and the direction of the guide ring can be adjusted by the flexible metal strip. The guide ring can be used to limit and organize the caliper harness body. Attached Figure Description
