Description

Technical Field

[0001] The utility model relates to the technical field of sensor parts, in particular to an automobile sensor connecting wire based on TPU material. Background Art

[0002] At present, the connecting wires of automobile sensors are mostly made of TPU material. TPU is a thermoplastic polyurethane elastomer rubber material with good elasticity, which makes the tensile strength of the connecting wire better. However, most of the connecting wires do not pay attention to the sealing performance, and the part connected to the automobile sensor is easy to accumulate dust.

[0003] For example, the invention with patent number CN201810873110.7 discloses a connecting wire for automotive sensors, which relates to the technical field of sensor parts, including a plurality of pins, the outer surface of the pins is covered with an inner sleeve, the outer wall of the inner sleeve is provided with a transmission line, the transmission line is fixedly connected to the corresponding pins through a connecting terminal, the outer side of the connecting terminal is covered with a heat shrink sleeve, the inner sleeve and the heat shrink sleeve are covered with an outer sleeve; the other end of the transmission line is connected to two connecting clips and then fixedly connected through a tail clip terminal, and a plurality of transmission lines are covered with a bellows on the outer side. The pins and transmission lines are fixedly connected through the connecting terminals, and the signal transmission effect is good. The outer side of the connecting terminal is covered with a heat shrink sleeve. When the outer sleeve is injection molded, the high temperature will make the heat shrink sleeve tightly wrap around the outside of the connecting terminal, thereby achieving a sealing effect; the bellows can collect the transmission lines together to prevent the transmission lines from being loose, thereby achieving an isolation and protection effect; multiple isolation protections improve the safety of the connecting lines, and the defective rate is also reduced;
