Description

A circuit breaker with multiple sets of terminals

technical field

The utility model relates to the field of manufacturing technology, in particular to a circuit breaker with multiple groups of terminals.

Background technique

At present, in existing residential areas, the function of the electric energy metering box is relatively simple, usually for each household. If there is a situation where multiple meter boxes need to be installed in one installation location, it is often necessary to install a cable branch box separately or set up a cable for each household. In this way It brings great inconvenience to the construction, prolongs the construction period, wastes construction materials, and increases construction costs.

Utility model content

Aiming at the structural deficiencies in the prior art, the utility model provides a flexible and multi-purpose terminal without changing the rated capacity of the original circuit breaker, which has simple construction, low cost, and short construction period with multiple sets of wiring terminals. side circuit breaker.

The technical solution of the utility model to solve the above-mentioned technical problems is as follows: a circuit breaker with multiple sets of terminals, including a circuit breaker body, and the circuit breaker body includes A\B\C three-phase wiring holes, and is characterized in that it also includes a branch Line assembly, the sub-line assembly includes A\B\C bending lugs, and A\B\C three bus bars, the upper end of the bending lug is provided with a circuit breaker connection hole, and the lower end is provided with a bus bar row connection holes and outlet connection holes, the three busbars A\B\C are fixedly connected with the three busbar connection holes of A\B\C respectively, and are respectively formed on the left, right and below of the three-phase connection holes The first, second, and third groups of three-phase terminals are provided, and the upper end of the bent lug is connected to the circuit breaker through the circuit breaker wiring hole.

The beneficial effects of the utility model are: under the premise of not changing the rated capacity of the original circuit breaker, a flexible and multi-purpose terminal is added, the construction is simple, the cost is low, and the construction period is short.

On the basis of the above technical solutions, the utility model can also be improved as follows.

Further, the bus bar is covered with an insulating sleeve.

The beneficial effect of the utility model is that each busbar is insulated and short circuit is not easy.
