Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker port structure. Background Art

[0002] The function of the circuit breaker port structure at the circuit breaker port is to prevent the wire from accidentally detaching from the connection point and ensure the stability and safety of the circuit. This type of structure usually includes a fixing clamp and an anti-detachment device. The fixing clamp is responsible for keeping the wire firmly connected to the port, while the anti-detachment device prevents the wire from loosening or detaching due to external force or vibration. In terms of structure, the fixing clamp is usually made of wear-resistant and corrosion-resistant materials to ensure long-term reliable use, and the anti-detachment device may adopt locking threads, spring clamping and other designs to increase the stability of the wire connection. These structures require precise manufacturing and assembly to ensure that they can play an effective role in various environments and use conditions. However, during the use of the circuit breaker port structure at this stage, the power-connected wire needs to be plugged into the circuit breaker port, and then the staff continuously screws the screws, and the end of the screw is pressed against the power-connected wire. Because the ports are often set in multiples, this results in the staff needing to perform a screwing operation every time they perform a wire plug-in operation. This operation process will be very time-consuming, especially in the case of a large number of circuit breaker ports, large projects or multiple wire connections. This time consumption will greatly increase the overall time cost of the circuit breaker installation project. Utility Model Content
