[0002] A switching-mode power supply (SMPS), also known as a switching power supply or switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage level into the voltage or current required by the user through various architectures. The input of a switching power supply is typically an AC power source (such as the mains) or a DC power source, while the output is typically for devices requiring DC power, such as personal computers. The switching power supply performs the voltage and current conversion between the two.

[0003] In the prior art, during the actual use of the switching power supply, the external device needs to be connected to the terminal block on the switching power supply through a connecting wire. When wiring, one end of the stripped connecting wire is placed on the terminal block, and then an auxiliary tool is used to tighten and fix the other end of the connecting wire to the terminal block with a screw to complete the wiring operation between the device and the switching power supply. However, this wiring method requires the use of tools for wiring, and when wiring multiple connecting wires, auxiliary tools need to be used to tighten and fix the connecting wires to the terminal block one by one with screws, which is cumbersome to operate, thereby bringing inconvenience to the wiring operation of the switching power supply.
