Description

Technical Field

[0001] The utility model belongs to the technical field of automotive wire harness pins, and particularly relates to a wire harness plastic bracket pin. Background Technique

[0002] With the development of China's automotive industry, the widespread use of electronics and the Internet, and the increasing number of electrical components on vehicles, the electrical safety of the whole vehicle has received more and more attention; as the transmission carrier of the vehicle's power supply, the safety and reliability of the vehicle wire harness have been increasingly emphasized. The wire harness needs to be firmly and reliably fixed and properly protected to avoid serious consequences such as electrical function failure and even vehicle ablation; the wire harness plastic bracket pin is a device used to fix the wire harness assembly inside the vehicle after being assembled with the wire harness plastic bracket body and the cable tie, which can effectively prevent the wire harness assembly from separating from the vehicle.

[0003] In today's highly developed electronic and electrical fields, the wire harness, as a key component connecting various electronic components and devices, plays an increasingly important role. The wire harness carries the transmission of electricity, signals, and data to ensure the normal operation of the system.

[0004] However, in actual applications, wire harnesses often need to be laid out and fixed in complex environments to avoid being affected by factors such as vibration, pulling, and friction. Traditional wire harness fixing methods may have many deficiencies. For example, metal bracket pins are relatively heavy, costly, prone to electromagnetic interference, and their performance is unstable in some special environments (such as high temperature, humidity, chemical corrosion, etc.).

[0005] With the continuous progress of plastic material technology, plastic bracket pins have gradually become a potential solution. Plastics have the advantages of light weight, low cost, good insulation performance, etc., which can effectively reduce the weight of the entire wire harness system, lower costs, and at the same time reduce the impact of electromagnetic interference.

[0006] In addition, with the trend of miniaturization and integration of electronic devices, the layout space of wire harnesses is becoming more and more limited, which also puts higher requirements on the size and shape of bracket pins. Through optimized design, new wire harness plastic bracket pins can better adapt to narrow spaces and achieve efficient wire harness fixing and protection.

[0007] In industries such as automotive, aerospace, and communication, extremely high requirements are placed on the reliability and stability of wire harnesses. Therefore, developing high-performance wire harness plastic bracket pins to meet increasingly stringent technical standards and application requirements has become an important research direction in the current related fields.

[0008] The existing fixing brackets for wire harnesses cannot fix wire harnesses with different cross-sectional sizes, have low practicability, and are not convenient for assembly and disassembly; the previous bracket pins are prone to excessive wear during high-speed operation, affecting service life and stability; the installation and maintenance of traditional bracket pins are relatively complex, increasing the downtime and maintenance costs of the equipment.
