Description

Technical Field

[0001] The utility model belongs to the technical field of circuit breakers, and in particular relates to a circuit breaker with a line bending protection structure. Background Art

[0002] A circuit breaker is a switching device that can close, carry and interrupt current under normal circuit conditions and can close, carry and interrupt current under abnormal circuit conditions within a specified time.

[0003] After installation, the existing circuit breakers usually have their lines bent, and the bent lines do not have a protective function. Therefore, during subsequent maintenance, the lines will be pulled, which can easily lead to poor contact between the lines and the circuit breaker. In severe cases, the lines may be broken or damaged, requiring staff to replace them, thereby increasing the cost of use. Therefore, we propose a circuit breaker with a line bending protection structure. Utility Model Content

[0004] The purpose of the utility model is to provide a circuit breaker with a line bending protection structure.

The arc-shaped protection plate 1 and the arc-shaped protection plate 2 can protect the line, reduce the loosening of the joint when it is pulled, and prevent the situation where the pulling is serious and causes damage, thereby solving the problem that when the line is pulled, it is easy to cause poor contact between the line and the circuit breaker, which may cause the line to be broken or damaged in serious cases.
