Description

Technical Field

[0001] The utility model relates to the technical field of conductive clips, in particular to a conductive clip for a drawer-type circuit breaker. 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. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of a fuse-type switch and an over-undertemperature relay, and generally no parts need to be changed after disconnecting the fault current. At present, it has been widely used.

[0003] However, the conductive sheet used in the existing conductive clip adopts an integral structural design. In order to cope with the required conductive clips of different sizes, multiple sets of conductive sheet molds need to be opened, which increases the production cost. At the same time, in the existing conductive clip, the conductive sheet is designed as a sheet. After long-term use, the current passing through the conductive clip will cause the temperature of the conductive sheet to rise rapidly, and there will be bending and deformation.

The surface of the connecting pin 4 is located between the two groups of conductive sheet assemblies 3 and is fixedly connected with a reinforcing rib 5.
