[0001] The utility model relates to the technical field of circuit breakers, in particular to a comb-shaped copper bar for electrical connection of multi-P circuit breakers. Background Technique

[0002] Circuit breakers are key components in the electrical industry and are widely used in electrical control. Normally, it can control the on-off of the circuit for power supply, power outage or conversion; in case of abnormalities such as overload and short circuit, it will automatically trip and cut off the power to protect the safety of personnel and equipment. With the progress of electrical automation, the number of distribution boxes has increased and the requirements have been improved. In a limited space, the number of circuit breakers has increased sharply. The traditional wiring method results in crowded space due to the complexity of cables, which is not convenient for later maintenance and increases the difficulty and time cost of maintenance.

[0003] Publication No. CN208571153U discloses a busbar for the busbar connection of miniature circuit breakers in a DC busbar box. The busbar is designed with a body, and a plurality of busbar teeth are longitudinally arranged on one side edge. The front end of each tooth has a transverse input head connected as a whole, which is convenient for connecting the miniature circuit breaker. One end of the busbar body is provided with a main circuit lapping hole. The busbar of the utility model and the busbar teeth are of an integral structure, which is not conducive to subsequent installation and maintenance. Therefore, a comb-shaped copper bar for electrical connection of multi-P circuit breakers is proposed to solve the above problems. Content of the Utility Model

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A comb-shaped copper bar for electrical connection of multi-P circuit breakers includes a busbar. The busbar is a long strip-shaped copper bar, and a plurality of comb-shaped rows are welded on the busbar. The comb-shaped rows are connected to the circuit breaker. One end of the busbar is provided with a connection hole for connecting a circuit. Insulators are arranged below both ends of the busbar for fixing the device in the electrical box.

[0007] Further, the number of busbars is adapted to the number of poles of the circuit breaker, and the number of comb-shaped rows is adapted to the number and number of poles of the circuit breaker.

[0008] Further, the comb-shaped row is made of purple copper and can be bent to adapt to the space of the electrical box. Compared with the prior art, the technical solution of the present application has the following beneficial effects:
