Problems solved by technology
[0002] The traditional electronic lock circuit connection method is a wiring structure, which has high requirements for the connection and installation of PCB boards, SMT boards and electrical equipment control technology, which increases the signal loss caused by the traditional wiring harness connection. It is not firm enough and reliable, which greatly increases the hardware cost of the whole machine solution, greatly increases the man-hours of the whole machine assembly, and the labor cost increases accordingly. All the components of the electronic lock circuit of the welding connection type of the present invention adopt the welding method to realize the electric signal 0 wire harness transmission, the battery processing board and the main board are connected by shrapnel, without wiring, the research and development design of this technology will change the connection and processing methods of electronic lock circuits in the future market
