There are static contact, the first binding post and the second binding post to be located at left and right sides of arc-chutes, the static contact and the second binding post
Electrical connection, the tripping mechanism includes yoke, armature, bimetal leaf, institute between the first binding post and arc-chutes
The yoke and armature stated are U-shaped structure, and its opening is oppositely arranged, and bimetal leaf is threaded through in yoke, lock be equipped with
The elongated end that armature is connected, the armature are hingedly fixed in by hinge column on shell, are also integrally formed on the shell
It is useful for separating arc-chutes and operating mechanism and the partition board of arc-chutes and tripping mechanism, be also installed on the hinge column
Make armature towards the torsional spring moved with yoke detaching direction, one end of the torsional spring acts on armature, the other end of the torsional spring
It acts on partition board, 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 the partition board is provided with one at the lower end of bimetal leaf
Angle, the yoke are installed in shell, and equipped with the elastic presser feet that extends downwardly, and the elasticity presser feet is by bimetallic
The lower end of piece is pressed abd fixed in the angle of the partition board.
The beneficial effects of the invention are as follows：Using the above structure, compared to the patent applied before, the present invention uses torsional spring first
Tension spring is substituted, the torsional spring can be mounted directly and be fixed on hinge column, and lead arc plate without additionally introducing, so that this hair
Bright structure is simpler, and installation is also more convenient.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 will not influence the stability of its connection during dropout bimetal leaf deforms and swings.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 partition board, is not only connected
Securely, and without additionally introducing flow distribution plate and metal frame, therefore not only make the structure of the present invention simpler, install also more
Add conveniently, and yoke is connected by the pressing of its elastic presser feet and bimetal leaf, the yoke is whole to be also used as one point
Part is flowed, to make breaker that there is better breaking capacity.
The present invention can be further arranged to the angle and is crossed to form by a vertical plane and an inclined surface, the vertical plane
It fits and abuts backwards to the end face of elastic presser feet with the bimetal leaf, the lower face phase of the inclined surface and the bimetal leaf
Fitting abuts.In this way, can enable elastic presser feet that the lower end of bimetal leaf is pressed abd fixed on 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 is equipped with the bending end extended backwards to armature direction for the yoke, one on shell
The slot being inserted into for the bending end is formed, and the both sides of the slot are additionally provided with the location hole to connect, the bending of yoke
It is locked by bolt between end and the location hole.Yoke can be fixed in shell by setting securely in this way, no
So that the overall performance of product is more stablized, and is also beneficial to the elastic presser feet in yoke and is firmly pressed against bimetal leaf.
