Problems solved by technology
[0002] With the technical development of electronic control components such as PCB, its application is becoming more and more extensive, but the existing PCB components have the following problems: usually PCB components are connected to the power supply through soft connections such as wires, due to the connection between the wires and electrical components The stability of the terminal is poor, and it is easy to cause connection failure due to external factors such as vibration or aging during use. The reliability is low, which affects the service life and increases the maintenance cost. It increases the manufacturing difficulty and cost of the production line; it is not conducive to the reduction and optimization of the size of the whole machine; in addition, due to the low integration of PCB electronic control components in existing power tools, the structure is not compact, and it takes up more space, which is not conducive to the whole machine miniaturization and miniaturization of
