Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and particularly to a multi-terminal direct-insert through-hole reflow connector for a headlight domain controller and an assembly method thereof. Background Art

[0002] In a vehicle domain controller, the connection between the wire end and the circuit board is usually achieved by inserting the male end into the female end. Specifically, the outer part of the female end housing of the connector is connected to the device housing by a buckle. One end of the male terminal is welded to the circuit board, and the other end is connected to the female end inside the male end housing inserted into the female end housing. However, this connection method has the following problems: First, the position of each component of the connector needs to be precisely designed, and due to the high assembly accuracy requirements, the assembly difficulty is relatively large. Second, during the use of the connector, problems such as poor contact or terminal damage are likely to occur in the connection between the multi-pin terminals and the circuit board. Since the terminals pass through the female end housing, it is difficult for maintenance personnel to directly inspect and repair the connection part. Usually, the terminals need to be de-soldered from the circuit board first, and then the female end housing needs to be disassembled. Moreover, since the female end housing surrounds the terminals, this may involve the disassembly of more components, which not only increases the maintenance cost and maintenance time, but also may cause new problems during the disassembly and re-assembly process. Summary of the Invention
