With the development of spacecraft control technology towards high precision and intellectualization, more and more components and parts are arranged in a controller, wiring is increasingly complex, the problems of time cost, price cost, labor cost and reliability brought by the manufacture of cables are not neglected in preparation work, extra resistors and inductors are added to a system by too many and too long cables, so that an electric loop cannot achieve the expected function, and the method is particularly obvious in environments of using a large-capacitance-value capacitor and the like. Meanwhile, a large number of wiring terminals occupy a large amount of space, and welding wires in the controller are difficult to realize and cannot adapt to the complex installation environment in the controller.
