Description
Technical field
The present invention relates to a kind of breaker.
Background technology
To improve the breaking capacity of breaker, and more reasonably arrange the position of each component in breaker, applicant
Applied for the patent of invention that a publication No. is CN103560058 A before, but in above-mentioned patent, its bimetal leaf is
It is connected with the first binding post by a flow distribution plate, while also needing to set a metal to install fixed flow distribution plate and bimetal leaf
Frame, so that do not only result in product structure and complicate, trouble is installed, and because bimetal leaf can deform during dropout
Swing, therefore it passes through flow distribution plate and such indirect connections is connected with the first binding post, stability is not good enough.Additionally,
In above-mentioned patent, to make armature keep being moved towards the direction for yoke separate, there is provided an extension spring, while to ensure extension spring
Two ends link fixed introducing again and lead arc plate, so also cause the complex structure of product, install trouble.
The content of the invention
In view of the shortcomings of the prior art, the invention provides a kind of structure it is simpler, install that more convenient and performance is more preferable
Breaker.
To achieve the above object, the invention provides a kind of breaker, housing is included, is provided with described housing and gone out
Arc chamber, operating mechanism, tripping mechanism, the first binding post and the second binding post, operating mechanism are located at arc-chutes top, and include
Mutually the operation handle of linkage, tripping, lock and action contact frame, are provided with moving contact on action contact frame, and the side of moving contact is set
There is static contact, the first binding post and the second binding post are located at the arc-chutes left and right sides, the static contact and the second binding post respectively
Electrical connection, described tripping mechanism is located between the first binding post and arc-chutes, and includes yoke, armature, bimetal leaf, institute
The yoke and armature stated are U-shaped structure, and its opening is oppositely arranged, and bimetal leaf is located in yoke, lock be provided with
The elongated end that armature is connected, the armature is hingedly fixed on housing by articulated column, is also integrally formed on described housing
Have for separating arc-chutes and operating mechanism and arc-chutes and the dividing plate of tripping mechanism, be also equiped with described articulated column
Make armature towards the torsion spring moved with yoke detaching direction, one end of the torsion spring is acted on armature, the other end of the torsion spring
Act on dividing plate, the upper end of bimetal leaf is hanging, and is electrically connected with action contact frame by the first soft conductor wire, bimetal leaf
Lower end is electrically connected by the second soft conductor wire with the first binding post, and described dividing plate is provided with one at the lower end of bimetal leaf
Angle, described yoke is installed in housing, and is provided with the elastic presser feet for extending downwardly, and the elastic presser feet is by bimetallic
The lower end of piece is pressed abd fixed in the angle of the dividing plate.
The beneficial effects of the invention are as follows：Using said structure, compared to the patent applied before, the present invention uses torsion spring first
Extension spring is substituted for, the torsion spring can be mounted directly and be fixed on articulated column, and need not additionally introduce and lead arc plate, hence in so that this hair
Bright structure is simpler, installs and also more facilitates.Secondly as in the present invention, the upper end of bimetal leaf is soft by first
Property conductor wire is electrically connected with action contact frame, and the lower end of bimetal leaf is electrically connected by the second soft conductor wire with the first binding post, because
This is during dropout, even if bimetal leaf deforms to swing does not interfere with its stability for connecting yet.Finally, directly pass through
Extend an elastic presser feet in yoke, the lower end of bimetal leaf is pressed abd fixed in the angle of the dividing plate, not only connect
Firmly, and need not additionally introduce flow distribution plate and metal frame, therefore not only cause that structure of the invention is simpler, installs also more
Plus conveniently, and yoke is connected by its elastic presser feet with the pressing of bimetal leaf, and the yoke is overall also can be used as one point
Stream part, so that breaker has more preferable breaking capacity.
The present invention can be further arranged to described angle and is crossed to form by a vertical plane and an inclined plane, the vertical plane
Dorsad the end face of elastic presser feet fits and abuts with the bimetal leaf, the lower surface phase of the inclined plane and the bimetal leaf
Laminating is abutted.So set, can enable elastic presser feet that the lower end of bimetal leaf is pressed abd fixed on into the angle more securely
Interior, even if during dropout, the upper end of bimetal leaf deforms swing, nor affects on the reliability of its connection.
The present invention may further be provided as the yoke is provided with the bending end that dorsad armature direction extends, one on housing
The slot for bending end insertion is formed, and the both sides of the slot are additionally provided with the location hole for connecting, the bending of yoke
It is locked by bolt between end and the location hole.So setting can be fixed in housing yoke securely, no
Only make the overall performance of product more stablize, and be also beneficial to the elastic presser feet in yoke to be firmly pressed against bimetal leaf.
