A connection line for a car sensor

Abstract

The invention discloses a connecting wire for automobile sensors. The invention relates to the technical field of sensor parts. The connection wire comprises a plurality of pins, wherein the pins areexternally wrapped with an inner wrapping sleeve, the outer wall of the inner wrapping sleeve is provided with transmission lines, the transmission lines and the corresponding pins are fixedly connected through connection terminals, the outer sides of the connection terminals are provided with a heat shrinkable sleeve each, and the inner wrapping sleeve and the heat shrinkable sleeves are externally wrapped with an outer sleeve. The other ends of the transmission lines re connected with two connecting clips and then fixedly connected with the tail clip terminals. Bellows are put on the outer sides of the transmission lines. The pins and the transmission lines are fixedly connected through the connection terminals, so that the signal transmission effect is good; the heat shrinkable sleevesare arranged on the outside of the connection terminals, and when the injection molding of the outer sleeve is used, the heat shrinkable sleeves are tightly wrapped on the outside of the connection terminals by the high temperature, so that the sealing effect is achieved; the bellows can concentrate the transmission lines together in a sleeving manner to prevent the transmission line from geetingloose, thereby playing a role in isolation and protection; multiple isolation and protection improves the safety of connecting wires and reduces the rate of defective products.

Description

technical field [0001] The invention relates to the technical field of sensor parts, more specifically, it relates to a connection line of an automobile sensor. Background technique [0002] With the development of social science and technology, cars have generally entered people's lives. Cars are a collection of high-tech content. There are various sensors inside the car, and the sensors need to communicate with the car's control system. [0003] In view of the above-mentioned problems, the Chinese patent whose patent announcement number is CN204118413U proposes a kind of ABS sensor plug, which comprises a plug injection molding body and a cable connected to the tail of the plug injection molding body. The injection molding body of the plug is inside, and the terminal is provided at the port. The injection molding body of the plug is also provided with a terminal skeleton, and the wiring terminal is embedded in the wiring terminal skeleton. [0004] In the process of use i...

Problems solved by technology

[0004] In the process of use in the above patent, since the cable is directly penetrated into the injection molding body of the plug, a gap will be formed at the connection between the cable and the injection molding body of the plug. When water mist or rainwater enters the gap, the sensor signal will be seriously affected. conductivity
