Description
Technical field
The present invention relates to a kind of breaker of plastic casing, more particularly, to a kind of bimetal leaf connection structure of breaker of plastic casing.
Background technique
Breaker of plastic casing can automatically cut off electric current after electric current is more than escape setting.Plastic housing refers to using plastic insulation
As the shell of device, it is used between insulated conductor and ground metal portion.Breaker of plastic casing usually contains pyromagnetic escape
Unit, and the breaker of plastic casing of big model can be equipped with solid-state escape sensor.Its trip unit is divided into：Thermo magnetic trip release and electronics are de-
Detain device.
Directly-heated type breaker of plastic casing is more common one kind, currently, the connection of existing directly-heated type breaker of plastic casing is led
Body is directly welded on bimetal leaf, and this connection type causes connection conductor and bimetal leaf contact position resistance larger, double
Sheet metal fusing point is not again usually high, along with the residual stress after welding influences, the bimetallic when being subjected to biggish short circuit current
Piece is easy fusing.
Summary of the invention
The purpose of the present invention is to provide a kind of bimetal leaf connection structures of breaker of plastic casing, to solve in the prior art
Being directly welded to connect conductor there are problems that being easy that bimetal leaf is made to fuse on the bimetal leaf of directly-heated type breaker of plastic casing.
For this purpose, the present invention uses following technical scheme：
A kind of bimetal leaf connection structure of breaker of plastic casing comprising bimetal leaf and connection conductor, wherein described double
Transition connecting plate, the bending plate of the transition connecting plate generally " L " type are fixed at the top of sheet metal comprising the first connection
Portion and second connecting portion, the first connecting portion are connect with the bimetal leaf, and the connection conductor is fixedly welded on the second company
In socket part, the fusing point of the transition connecting plate is higher than the fusing point of the bimetal leaf.
Particularly, the first connecting portion is by being welded and fixed or riveting the top for being fixedly connected on the bimetal leaf.
Particularly, the second connecting portion is vertically arranged, and the connection conductor is fixedly welded on the second connecting portion
Medial surface.
Particularly, the second connecting portion is vertically arranged, and the connection conductor is fixedly welded on the second connecting portion
Lateral surface.
Particularly, the transition connecting plate is by copper sheet one bending and molding.
Particularly, the connection conductor includes connecting line and connecting plate, and one end of connecting line is fixedly installed on connecting plate,
The other end is fixedly welded in second connecting portion.
Beneficial effects of the present invention are that the bimetal leaf connection structure of the breaker of plastic casing is added compared with prior art
Have a transition connecting plate, the welding of connection conductor in transition connecting plate, transition connecting plate using higher melting-point material, be allowed to hold
By can prevent from fusing when biggish short circuit current.It is not only simple in structure, it is easy to accomplish；And it can effectively avoid bimetal leaf
Fusing easily, it is ensured that the reliable and stable work of breaker of plastic casing.
Detailed description of the invention

Transition connecting plate 3, transition connecting plate 3 is by the L-shaped structure of copper sheet one bending comprising first connecting portion 30 and the second connection
Portion 31, the top that first connecting portion 30 is connected to bimetal leaf 1 by being welded and fixed or riveting fixed any mode, connection
Conductor 2 includes connecting line 20 and connecting plate 21, and one end of connecting line 20 is fixedly installed on connecting plate 21, and the other end is welded and fixed
In in second connecting portion 31, the fusing point of transition connecting plate 3 is higher than the fusing point of bimetal leaf 1, is allowed to bear biggish short circuit electricity
It can prevent from fusing when stream, avoid the fusing easily of bimetal leaf 1.
Second connecting portion 31 is vertically arranged, and when connecting line 20 is welded to connect, can be arranged and be needed connecting line according to equipment
20 are fixedly welded on the medial surface or lateral surface of second connecting portion 31.
The above embodiments only describe the basic principles and characteristics of the invention, and the invention is not restricted by the above cases,
Without departing from the spirit and scope, the invention also has various changes and changes, and these changes and changes are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
