Double-row and multi-row connectors can provide higher pin density within a limited space and are suitable for complex circuit connection requirements. The multi-row multi-pin connector can better balance space occupation, electrical performance, and mechanical reliability, etc.

[0003] A multi-row multi-pin connector generally includes a plastic fixing base and multiple pins. One end of the multiple pins is used for electrical connection with other connectors or circuit boards, etc., and the other end needs to be welded to the connection wires in the cable one by one to form a connection module, so as to be connected with other electrical appliances to achieve the transmission of current or signals. In the prior art, for the welding of pins and wire cores, it is necessary to manually comb the connection wires, and then manually weld the pins and the wire cores of the connection wires in the specified wire sequence. Since the pins and the connection wires are densely arranged in a limited space, during the welding process, the workload is large, the positioning between the pins and the wire cores of the connection wires depends on manual operation, the positioning is troublesome, and the error rate is high.
