Description

Static contact assembly for frame

Technical Field

The utility model relates to a circuit breaker technical field especially involves a static contact subassembly for frame.

Background

The static contact is mainly used on a contact box in a high-low voltage switch cabinet or a circuit breaker, and in the static contact component structure of the existing frame circuit breaker, an arc striking sheet and the static contact are generally connected by adopting a copper rivet, the copper rivet is generally nonstandard, the customization cost is higher, a plurality of parts are mutually matched, the precision after riveting is poorer, and the assembly time is more.

Disclosure of Invention

The utility model aims at solving the above problems existing in the prior art and providing a static contact component for a frame.

In order to realize the above purpose, reach above-mentioned effect, the technical scheme of the utility model as follows: the utility model provides a static contact subassembly for frame, includes static contact, run-on arc piece, insulation board, its characterized in that: the top surface of the static contact is provided with a silver point and a convex hull, the convex hull is provided with an arc striking sheet, and the insulating plate is arranged between the arc striking sheet and the static contact and is connected with the static contact by penetrating through the arc striking sheet and the insulating plate through screws.

Preferably: the static contact is shaped like a 7.

Preferably: and the static contact and the silver point are riveted and fixed through a rivet.

Preferably: the convex hull and the arc striking sheet are fixed through pressure riveting.

Preferably: and a chamfer is arranged at the top end of the convex hull.

Compared with the prior art structure, the utility model, beneficial effect as follows:

1. the utility model discloses simple structure through set up the convex closure on quiet contact, has improved the location of run-on arc piece effectively, and simple to operate is swift, has avoided the use and the positioning accuracy scheduling problem of copper rivet, the effectual cost of having practiced thrift.

2. The silver point and the static contact are fixed through a rivet-free riveting process, and compared with a spot welding process, the quality is more controllable, and the defects of welding damage, slag inclusion and the like are avoided.
