Vehicle tire pressure monitoring antenna protection device

Abstract

The invention relates to a device for protecting a wire rod, in particular to a protection device for a monitoring antenna of vehicle tire pressure; the protection device is sleeved on the monitoring antenna and is provided with a connection sleeve and a protection sleeve; the connection sleeve is provided with a main body and a contracting part which is fixedly connected with the main body and can be collected; an insertion hole for allowing the monitoring antenna to be inserted is formed in each of the main body and the contracting part respectively; the protection sleeve is detachably connected with the connection sleeve and is provided with a matching part for extruding the contracting part to be collected to enable the contracting part to clamp the monitoring antenna inserted into the contracting part when the protection sleeve and the connection sleeve are connected. By adopting the technical scheme, the protection for the monitoring antenna is realized, the monitoring antenna is prevented from being exposed in air, and the protection device for the monitoring antenna of the vehicle tire pressure is simple in structure, and convenient to mount and disassemble.

Description

technical field [0001] The invention relates to a device for protecting wires, in particular to a vehicle tire pressure monitoring antenna protection device. Background technique [0002] The tire pressure monitoring antenna is generally a wire drawn from the BCM. One end of this wire is installed in the BCM connector of the automobile wiring harness and connected with the BCM module to form an antenna. The other end of the wire is generally exposed directly to the In the air, or directly wrapped with insulating tape for simple protection of the antenna, but with this method, the tape will age and fall off as time goes on, causing the copper wire of the antenna to rust and oxidize, and even the copper wire is in contact with the body sheet metal However, it is interfered by the clutter transmitted on the vehicle body, which affects the accuracy of the signal. In addition, most tire pressure monitoring antennas generally use 0.5mm wires. Because the wires are too thin, when ...

[0002] The tire pressure monitoring antenna is generally a wire drawn from the BCM. One end of this wire is installed in the BCM connector of the automobile wiring harness and connected with the BCM module to form an antenna. The other end of the wire is generally exposed directly to the In the air, or directly wrapped with insulating tape for simple protection of the antenna, but with this method, the tape will age and fall off as time goes on, causing the copper wire of the antenna to rust and oxidize, and even the copper wire is in contact with the body sheet metal However, it is interfered by the clutter transmitted on the vehicle body, which affects the accuracy of the signal

In addition, most tire pressure monitoring antennas generally use 0.5mm wires. Because the wires are too thin, when the ends of the wires are not fixed, the wires will hang and shake, and there will also be a risk of contact with the sheet metal, which will also affect the reliability of signal transmission. In terms of wire harness processing, since the wires are idle bare wires, there is no corresponding electrical inspection module when the wire harness loop detection station detects, so the detection is very inconvenient. Some wire harness factories do not even detect, and there is a hidden danger of loop errors.
