Description
Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a vehicle-mounted connector. Background Art
[0002] At present, automotive connectors are a component that electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits within the circuit, so that current can flow and the circuit can achieve the predetermined function. The automotive connector mainly includes terminals and insulators. The terminals are assembled in the insulators. For some automotive connectors, they need to be assembled with the PCB circuit board on the car. In the prior art, the metal terminals on the automotive connector are assembled with the PCB circuit board through the DIP plug-in process. The DIP plug-in process can be roughly divided into plug-in, wave soldering, pin cutting, inspection, testing and other processes. The terminal modules in the structure are all designed as a whole. The product stability is poor during the production process, and the welding feet of each connection port are prone to bending. When a single welding foot is bent, it is easy to cause the entire product to be scrapped; in addition, during the assembly process, the number of terminals at each connection end cannot be adjusted based on different usage scenarios, and the adaptability is not strong;
[0003] Therefore, the present application proposes a vehicle-mounted connector, in which the terminal module is designed as a separate substrate, which reduces the defective rate during assembly and use. At the same time, it can be adaptively assembled based on different usage scenarios, and has better adaptability. Utility Model Content
