Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to an automotive door lock wiring harness switch. Background Technology

[0002] Electric vehicle door locks are a critical component of the vehicle's electrical system, and their on / off status directly affects the normal operation of functions such as door status detection, interior lighting, and safety warnings. Currently, the most common automotive door lock switches on the market employ the following two installation methods: 1. Screw fixing method: The switch is fixed to the car door or door lock mechanism with screws. This method of installation is cumbersome, requires auxiliary tools, increases the assembly time and labor costs on the production line, and the screws are prone to loosening under long-term vibration, affecting the reliability of the connection. 2. Plastic interference fit: Fixing is achieved through an interference fit between plastic housings. Although installation is relatively simple, the bonding strength is usually insufficient. Under frequent use or extreme temperature conditions, plastic deformation and loosening of the fit can easily occur, leading to decreased sealing performance and even poor electrical contact. Both of the above methods have problems such as complex structure, low assembly efficiency, and insufficient long-term reliability. Especially with the higher requirements for waterproofing, dustproofing, and vibration resistance of electric vehicles, there is an urgent need for a car door lock wiring harness switch that is simple in structure, quick to install, has a firm connection, and excellent sealing performance.
