The existing electronic control boards on the market need to add additional finished terminal blocks on the circuit boards to solve the problems of electronic control testing and connection. The finished terminal blocks are basically fixed in a single layout, which makes them unable to adapt to different electronic control layouts and on-site wiring scenarios, resulting in inconvenience in installation and poor user experience. In addition, the terminal blocks need to be welded and fixed on the circuit boards. Therefore, the terminal blocks need to be made of high-temperature resistant materials, which has a high cost of use. Utility Model Content
