Technical Field

The utility model relates to a movable contact mechanism of a universal circuit breaker, and belongs to the field of circuit breakers.

Background

The universal breaker is also called a frame type breaker, and is a mechanical switching device which can be used for switching on, carrying and breaking current under normal circuit conditions and also can be used for switching on, carrying for a certain time and breaking current under specified abnormal circuit conditions. The universal circuit breaker is used for distributing electric energy and protecting overload, undervoltage, short circuit and the like of a circuit and power supply equipment.

Such circuit breakers typically have a steel frame in which all of the components are mounted. The capacity is larger, a plurality of functional releases and a plurality of auxiliary contacts can be arranged, has higher sectioning capability and thermal stability, so is often used in places requiring high breaking capability and selective protection. The design of the movable contact of the conventional universal circuit breaker generally occupies an excessive volume and is easily limited by external environment in the use process.

Disclosure of Invention

The utility model aims to overcome the defects and the shortcomings of the prior art and provides a movable contact mechanism of a universal circuit breaker.

Preferably, the fixed seat is connected with the installation piece in stretching out of conducting block one end, the installation piece tip is circular, be equipped with a plurality of spliced eye on the installation piece, the spliced eye can realize the arc extinguishing effect that opens circuit with external environment grafting.

Furthermore, the plug holes are distributed in four corners, the positions of the plug holes can be changed according to actual conditions, and the adaptability to external equipment is improved.

Furthermore, the moving contacts are connected in parallel through a fixed shaft, and two ends of the fixed shaft are rotatably arranged on the fixed side plate, so that the moving contacts can rotate along the fixed shaft.

Preferably, the flexible conductive connecting wire is made of copper, has good conductivity and is easy to obtain.

Furthermore, the contact seat is provided with a partition board at intervals, and the partition board is inserted into a gap between the moving contacts to further limit the moving direction of the moving contacts, so that the problem of short circuit caused by mutual contact between the moving contacts is avoided.

The beneficial effects of the utility model are as follows: through setting up 13 moving contacts on insulating support, the fixed curb plate of rethread is fixed with the mount pad, compares in the moving contact mechanism of traditional omnipotent circuit breaker, has reduced the volume to fixed effectual, when connecting, only need carry out the electricity through the conducting block and connect can.
