Abstract
The utility model 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 in by axle on the contact mounting bracket, moving contact and the contact mounting bracket is 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 that is flexible coupling to moving contact, binding face of another road through contact mounting bracket and moving contact 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 are met under breaker same volume in matching, the requirement that high current passes through temperature rise.
Description
Technical field
The utility model is related 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 transmission is by thermal source part, the clamping binding face through moving contact rack and moving contact, then is flowed through through moving contact.Two, it is flexible coupling
Mode, the transmission of its electric current is by 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 laminating contact surface meet breaker temperature increase requirement, simple in construction；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, it is raised to after 800A and the above, connected mode one is too small due to the conductive section of clamping,
The temperature increase requirement of breaker can not be met, though connected mode two can meet the section that high current passes through, because breaker
Volume does not increase, the wire increase being flexible coupling, and causes moving contact after welding not rotate flexibly, crowded lead that be flexible coupling occurs
The phenomenon pulled.
Utility model content
The purpose of this utility model is to provide a kind of moving contact of breaker attachment structure, its situation in constancy of volume
Under, requirement of the breaker high current to temperature rise is met, to solve the above mentioned problem that breaker is present in the prior art.
For up to this purpose, the utility model 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 in by axle on the contact mounting bracket, 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 bottom plate, and two sides of the bottom plate are upward
It is extended with side plate, two side plates corresponding offer and axle is installed in axis hole, the axis hole, 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 relative to the moving contact,
Its one end is connected on the side of the thermal source part, and the other end is connected on the side wall of the moving contact.
The beneficial effects of the utility model are that the electric current of the moving contact of breaker attachment structure is passed compared with prior art
It is defeated to be divided into two-way, wherein all the way through the wire transmission that is flexible coupling to moving contact, patch of another road through contact mounting bracket and moving contact
Conjunction face 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
Meet under breaker same volume, the requirement that high current passes through temperature rise.
