Description

Technical Field

[0001] The utility model relates to the technical field of brake wear alarm sensor plugs, in particular to a plug for an automobile brake wear alarm sensor with a dustproof mechanism. Background Art

[0002] The car brake wear alarm sensor is a sensor used to monitor the degree of wear of the vehicle's brake system. It is usually installed on the brake pads or brake discs. It determines whether the brake system needs to replace the brake pads by monitoring the distance between the brake pads and the brake discs or the degree of wear. The working principle of the brake wear alarm sensor is usually based on resistance changes or vibration detection. When the brake pads are worn to a certain extent, the sensor will send a signal to the vehicle's brake system or dashboard to remind the driver to replace the brake pads. When using the car brake wear alarm sensor, it needs to be installed and used through a plug.

[0003] The existing brake wear alarm sensor plug does not have a dustproof function and is easily invaded by external impurities such as dust and dirt during use, resulting in problems such as poor contact or short circuit, which will cause poor contact or failure of the sensor, thereby affecting the accuracy of the brake wear alarm system. The sensor may falsely report or miss the brake wear status, and increase the cost of repairing and replacing the plug, which will accelerate the wear of the plug and shorten its service life.
