Description

Power connection mechanism

Technical Field

The utility model relates to the technical field of circuit breaker related equipment, in particular to a power connection mechanism.

Background Art

Circuit breakers are terminal equipment for power distribution lines. They are small in size and modular in nature. They are mainly used to protect lines and are widely used in power distribution in homes, office buildings, communication base stations, and rural outdoor areas.

The intelligent circuit breaker drive device needs to obtain power from the circuit breaker. There are two common ways to obtain power:

1. Take power from the outside of the circuit breaker inlet. The disadvantage of this method is that the circuit breaker has a groove on the outside. After installation, a protective cover must be added and fixed with buckles or screws; and the circuit board needs to be welded to the power-taking piece, which has a complex structure and is difficult to assemble.

2. A through hole is reserved inside the circuit breaker, and the circuit board is equipped with a copper brass spring, which is inserted into the through hole and elastically contacts the incoming line connection board. The disadvantages of this method are: first, the through hole space is too large, and the circuit board is fixed by the components welded on it and the edge of the shell through hole, which is not firmly fixed; second, the spring is limited to brass, which is expensive; third, the contact method is a cantilever beam structure, and when the spring contacts the terminal board elastically, it is easy to deform due to force, and poor contact will occur during use; finally, the connection between the spring and the circuit board needs to be fixed with solder, which is complicated and difficult to operate.
