Description
Technical Field
The utility model relates to an universal circuit breaker technical field, concretely relates to long-life universal circuit breaker moving contact assembly.
Background
The universal circuit breaker is also called frame type circuit breaker, and is a mechanical switch electric appliance which can connect, bear and break the current under the normal circuit condition, and can also connect, bear and break the current for a certain time under the specified abnormal circuit condition. Conventional circuit breakers are used to distribute electrical energy and to protect lines and power equipment from overloads, undervoltages, short circuits, etc. The moving contact assembly of the conventional universal circuit breaker is unreasonable in structural design, so that the moving contact is easily burnt by electric arcs, and the moving contact assembly of the conventional universal circuit breaker has the defects of complex structure, unreliable performance and short service life.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, long service life, assemble convenient universal circuit breaker moving contact assembly.
In order to realize the above object, the utility model discloses a long-life universal circuit breaker moving contact assembly, including contact carrier, set up two curb plates on contact carrier's both sides respectively, set up contact cover on contact carrier, set up the pivot on contact carrier, the middle part of pivot on interval arrangement be provided with a plurality of long contacts, and be provided with contact spring between a plurality of long contacts and the contact carrier respectively, the pivot on both sides department that corresponds a plurality of long contacts be provided with the short contact respectively, short contact and contact carrier between be provided with the spring respectively, the one end of a plurality of long contacts be provided with the striking portion of bending respectively, the one end of short contact be provided with the portion of bending, the striking portion of bending highly be greater than the height of the portion of bending.
The moving contact assembly has the advantages that the moving contact assembly adopts a long contact and short contact combined structural design, the heat dissipation area of the moving contact assembly is increased, an arc striking bending part of the long contact can quickly introduce electric arcs into an arc extinguishing chamber, the electric arcs are quickly extinguished, and the service life of the moving contact assembly is prolonged, so that the moving contact assembly of the universal circuit breaker has the advantages of simple structure, stable and reliable performance, long service life and convenience in assembly.
Particularly, the contact support on correspond spring department and be provided with the storage tank, the spring setting in the storage tank, and correspond spring department on one side of short contact and be provided with the constant head tank, the one end of spring contradict in the constant head tank, and constitute the joint cooperation of short contact and spring. The spring clamps between contact support and short contact, the assembly of spring and contact support, short contact of being convenient for, assembly efficiency is higher, and can guarantee that short contact can reliably move, is favorable to improving this moving contact assembly reliability of working.

Fig. 2 is a cross-sectional view of an embodiment of the present invention.
Detailed Description
As shown in fig. 1-2, the embodiment of the present invention is a moving contact assembly of a long-life universal circuit breaker, comprising a contact support 10, two side plates 11 respectively disposed on two sides of the contact support 10, a contact cover 12 disposed on the contact support 10, a rotating shaft 13 disposed on the contact support 10, a plurality of long contacts 14 disposed at intervals on the middle portion of the rotating shaft 13, contact springs are respectively arranged between the plurality of long contacts 14 and the contact support 10, short contacts 15 are respectively arranged on the rotating shaft 13 corresponding to the two sides of the plurality of long contacts 14, springs 16 are respectively arranged between the short contacts 15 and the contact support 10, one end of each of the long contacts 14 is respectively provided with an arc striking bent part 141, one end of the short contact 15 is provided with a bending part 151, and the height of the striking arc bending part 141 is greater than that of the bending part 151.
As shown in fig. 2, a receiving groove 101 is provided on the contact holder 10 corresponding to the spring 16, the spring 16 is disposed in the receiving groove 101, a positioning groove 152 is provided on one side of the short contact 15 corresponding to the spring 16, one end of the spring 16 abuts against the positioning groove 152, and the short contact 15 is in clamping fit with the spring 15. The spring clamps between contact support and short contact, the assembly of spring and contact support, short contact of being convenient for, assembly efficiency is higher, and can guarantee that short contact can reliably move, is favorable to improving this moving contact assembly reliability of working.
This moving contact assembly adopts long contact and short contact combined type structural design, has increased the heat radiating area of this moving contact assembly, and the striking of long contact portion of bending can introduce electric arc in the arc extinguishing chamber fast, realizes extinguishing fast of electric arc, is favorable to prolonging the life of this moving contact assembly to this universal circuit breaker moving contact assembly has simple structure, stable performance is reliable, long service life, the convenient advantage of assembly.
