Abstract
The invention discloses a kind of moving contact of breaker attachment structure, it includes thermal source part, moving contact and contact mounting bracket, the thermal source part is connected on the contact mounting bracket, the moving contact is rotationally assemblied on the contact mounting bracket by axle, the moving contact and contact mounting bracket are made of electrically conductive material, wherein, at least one wire that is flexible coupling is connected between the thermal source part and the contact mounting bracket, the moving contact is close to set by limiting component with the contact mounting bracket.The electric current transmission of above-mentioned moving contact of breaker attachment structure is divided into two-way, wherein all the way through the wire transmission to moving contact that is flexible coupling, another road is transferred to moving contact through the binding face of contact mounting bracket and moving contact.So as to share the conductor cross-section being flexible coupling, flexible connecting line is set suitably to reduce quantity, both are met under breaker same volume in matching, the requirement that high current passes through temperature rise.
Description
Technical field
The present invention relates to a kind of breaker, more particularly, to a kind of moving contact of breaker attachment structure.
Background technology
At present, the existing connected mode for moving contact of breaker mainly has following two：One, clipping structure, its
Electric current is transmitted through thermal source part, through moving contact rack and the clamping binding face of moving contact, then is flowed through through moving contact.Two, it is flexible coupling
Mode, its electric current is transmitted through thermal source part, and through being flexible coupling, wire is finally flowed through by moving contact.Above-mentioned connected mode one is in low current
400A and following situation, the heating of contact surface of fitting meet breaker temperature increase requirement, simple structure；Connected mode two works as electric current
In the case of 630A, because the mode temperature increase requirement of connected mode one does not have surplus, therefore connected mode two is used, it is possible to increase electricity
The section of streaming, so as to meet requirement of the breaker to temperature rise.
But, when electric current is toward rising, after being raised to 800A and the above, connected mode one is too small due to the conductive section for clamping,
The temperature increase requirement of breaker cannot be met, though connected mode two can meet the section that high current passes through, because breaker
Volume does not increase, and the wire being flexible coupling increases, and moving contact cannot be rotated flexibly after causing welding, crowded the leading that be flexible coupling occur
The phenomenon pulled.
The content of the invention
It is an object of the invention to provide a kind of moving contact of breaker attachment structure, it is full in the case of constancy of volume
Requirement of the sufficient breaker high current to temperature rise, to solve the above mentioned problem that breaker is present in the prior art.
It is that, up to this purpose, the present invention uses following technical scheme：
A kind of moving contact of breaker attachment structure, it includes thermal source part, moving contact and contact mounting bracket, and the thermal source part connects
It is connected on the contact mounting bracket, the moving contact is rotationally assemblied on the contact mounting bracket by axle, it is described dynamic tactile
Head and contact mounting bracket are made of electrically conductive material, wherein, it is connected with least between the thermal source part and the contact mounting bracket
Piece wire that is flexible coupling, the moving contact is close to set by limiting component with the contact mounting bracket.
Especially, the overall " U "-shaped structure of the contact mounting bracket, it includes base plate, and two sides of the base plate are upward
Side plate is extended with, correspondence offers axis hole on two side plates, and axle is provided with the axis hole, and one end of the moving contact is arranged in
The elastomeric element for making moving contact be adjacent to side plate inwall is provided with the axle, and on the axle.
Especially, the moving contact is provided with two, and the elastomeric element is located on the axle between two moving contacts.
Especially, the wire that is flexible coupling is provided with two, and two flexible connecting lines are arranged symmetrically, and its one end is connected to described
On the side of thermal source part, the other end is connected on the side wall of the moving contact.
Beneficial effects of the present invention are that the electric current of the moving contact of breaker attachment structure transmits quilt compared with prior art
It is divided into two-way, wherein all the way through the wire transmission to moving contact that is flexible coupling, another road is through contact mounting bracket and the binding face of moving contact
It is transferred to moving contact.So as to share the conductor cross-section being flexible coupling, flexible connecting line is set suitably to reduce quantity, both match satisfaction
Under breaker same volume, the requirement that high current passes through temperature rise.
