Abstract
The utility model discloses a kind of moving contact of breaker clamp structure, it includes conducting bracket and two panels moving contact, the two panels moving contact is installed on the conducting bracket by rotating shaft, wherein, the elastic ring of deformation can radially be produced by being provided with rotating shaft between the two panels moving contact, it is provided with the conducting bracket for the limiting component spacing to two panels moving contact, the radially elastic force that the lateral wall of the two panels moving contact is produced by elastic ring is in close contact with the conducting bracket face with face.Above-mentioned moving contact of breaker clamp structure is not only simple in structure, and cost is low；And clamp reliable and stable, the size of elastic component can be substantially reduced on the premise of moving contact structure chucking power is not reduced, so that reserving more spaces is used to increase the sectional area of the part such as moving contact galvanic circle, the internal resistance in loop is reduced, the current class for raising cage creates basis.
Description
Technical field
The utility model is related to a kind of breaker, more particularly, to a kind of moving contact of breaker clamp structure.
Background technology
Modern society with science and technology continuous progress, the continuous lifting of breaker manufacturing process, net capacity is not
The need for disconnected increase and centralized power distribution, increasing breaker develops towards miniaturization, the direction of high breaking.Miniaturization meaning
To develop on the basis of smaller cage originally and can carry the breaker of more high current, while the disjunction index of breaker is not
Drop is anti-to be risen.Under this harsh design objective, traditional connected mode that is flexible coupling is limited to larger space, to moving contact
The inhibition of motion is larger, influences break, can not meet the demand of design.Although and existing clamp structure energy
Enough meet requires, but the volume past is huge, and contact and conducting bracket are arranged on the inside of rotating shaft and provide pressure by stage clip, by turning
Conjunction of the motion of axle to realize switch divides, and this structure constraint is in the intensity of rotating shaft, and inner space is limited, and stage clip needs to provide
Enough chucking powers, volume can not be too small, therefore this structure also is difficult to provide bigger space again for lifting conductive return
The sectional area on road.
Utility model content
The purpose of this utility model is to provide a kind of moving contact of breaker clamp structure, its have it is simple in construction, take
The characteristics of space is small and clamps reliable and stable, to solve above-mentioned the asking of moving contact of breaker clamp structure presence in the prior art
Topic.
For up to this purpose, the utility model uses following technical scheme：
A kind of moving contact of breaker clamp structure, it includes conducting bracket and two panels moving contact, and the two panels moving contact leads to
Rotating shaft is crossed to be installed on the conducting bracket, wherein, being provided with the rotating shaft between the two panels moving contact radially to produce
It is provided with the elastic ring of raw deformation, the conducting bracket for the limiting component spacing to two panels moving contact, the two panels is moved
The radially elastic force that the lateral wall of contact is produced by elastic ring is in close contact with the conducting bracket face with face.
Especially, the elastic ring is welded by helical spring head and the tail, generally circular.
Especially, the limiting component is two support arms being fixed on the outside of the conducting bracket.
The beneficial effects of the utility model are that the moving contact of breaker clamp structure passes through setting compared with prior art
Certain magnitude of interference, is compressed the radial dimension of elastic ring, and elastic ring produces elastic force because of size distortion, so that moving contact
Certain chucking power is produced between conducting bracket, the resistance in loop, which can be reduced to, uses scope.It is not only simple in structure, cost is low；
And clamping is reliable and stable, on the premise of moving contact structure chucking power is not reduced, can be substantially reduced the size of elastic component, from
And reserving more spaces is used to increase the sectional area of the part such as moving contact galvanic circle, the internal resistance in loop is reduced, to improve shell
The current class of frame creates basis.

Embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by embodiment.
Refer to Fig. 1 to Fig. 3 to show, in the present embodiment, a kind of moving contact of breaker clamp structure includes conducting bracket 1 and two
Piece moving contact 2, the two panels moving contact 2 is installed on the conducting bracket 1 by rotating shaft 3, between the two panels moving contact 2
The elastic ring 4 of deformation can radially be produced by being provided with rotating shaft 3, the conducting bracket 1 two outside be respectively and fixedly provided with for pair
The lateral surface of two panels moving contact 2 carries out spacing support arm 5.
The elastic ring 4 is welded by helical spring head and the tail, generally circular, by the footpath for compressing the elastic ring 4
To size, the external diameter of elastic ring 4 is set to produce recoverable elastic deformation in elastic range, so that elastic ring 4 produces one
Elastic force radially, i.e., apply pressure F to elastic ring 4, and the outer diameter D of elasticity of compression ring 4, elastic ring 4 can produce elastic force T.
The radially elastic force that the lateral wall of the two panels moving contact 2 is produced by elastic ring 4 and the face of conducting bracket 1 with
Face is in close contact, and constitutes galvanic circle.
Above example is to elaborate general principle of the present utility model and characteristic, and the utility model is not by above-mentioned example
Limitation, on the premise of the utility model spirit and scope are not departed from, the utility model also has various change and change, these changes
Change and change and both fall within the range of claimed the utility model.Scope is claimed in the utility model will by appended right
Ask book and its equivalent thereof.
