Background

Power control cabinets are a common component in the field of power switch control. The power control cabinet is used for installing various power equipment such as various switches and controllers for power control. All electronic components in the control cabinet are connected in a wiring mode, and the connection position of the electric wire and the electronic components is called a wiring terminal.

The wiring terminal in the prior art is generally fixed by screws. Taking a circuit breaker as an example, when an electric wire is connected to the circuit breaker, generally, an insulating rubber sheet at the head of the electric wire is detached, a conductive copper wire is inserted into a wiring position in the circuit breaker, and then a corresponding screw is screwed down to fix the electric wire. However, the above-described fixing method is likely to cause poor line contact because the wire is loosened due to the non-tightening of the screw. And because some control cabinets have more electronic components and complicated circuits, some electronic components in small space are difficult to screw by using a spanner.
