Problems solved by technology

But it has the following problems: 1. The fixing bolts of the connecting terminal are also kept in communication with the outside world through the jack for inserting the screwdriver, causing electric shock hazards; There is a possibility of water or other metal objects entering the hole where the wire is inserted and causing an electric shock accident
[0004] The patent with the publication number CN106783416A discloses a safety leakage circuit breaker and its use method. The terminal 3 includes a fixed terminal 31 and a U-shaped sliding terminal 32 to clamp the wire, but the wiring hole 14b for inserting the wire Without any protective measures, the gap between the wire and the wiring hole 14b after the wire is inserted has a large potential safety hazard

Abstract

The invention discloses a circuit breaker wiring method. A safety circuit breaker is used, and a circuit breaker main body and self-protection wiring terminals are included; the self-protection wiring terminals are symmetrically arranged on the left side, the right side, the front side and the rear side of the circuit breaker main body; and each self-protection wiring terminal at least comprises a terminal cavity, an opening and closing device, a wire clamping terminal and an operation device. The wiring method comprises the following steps: 1, opening and closing an opening and closing device; 2, conducting wire connection; 3, clamping the wire clamping terminals; and 4, adjusting damping.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a circuit breaker wiring method. Background technique [0002] Leakage circuit breaker is a switch that can automatically operate when the leakage current in the circuit exceeds a predetermined value, mainly to prevent personal electric shock. Some circuit breakers are also integrated with residual current protection. In the event of leakage, the tripping device operates to cut off the power of the circuit breaker. [0003] When the circuit breaker of the prior art is connected to the electric wire, the insulation sheath of the electric wire is stripped off, and then the conductive metal core is inserted into the terminal for fixing. But it has the following problems: 1. The fixing bolts of the connecting terminal are also kept in communication with the outside world through the jack for inserting the screwdriver, causing electric shock hazards; There is a possibility ...
