Description
Technical field
The utility model relates to a kind of breaker of plastic casing, connect knot more particularly, to a kind of bimetal leaf of breaker of plastic casing
Structure.
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.
Utility model content
The purpose of this utility model is to provide a kind of bimetal leaf connection structures of breaker of plastic casing, to solve existing skill
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 in art.
For this purpose, the utility model 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.
The beneficial effects of the utility model are, compared with prior art the bimetal leaf connection structure of the breaker of plastic casing
Have additional transition connecting plate, the welding of connection conductor in transition connecting plate, transition connecting plate using higher melting-point material, make
Receiving biggish short circuit current when can prevent from fusing.It is not only simple in structure, it is easy to accomplish；And it can effectively avoid double gold
Belong to the fusing easily of piece, it is ensured that the reliable and stable work of breaker of plastic casing.
Detailed description of the invention
Fig. 1 is the three-dimensional knot of the bimetal leaf connection structure for the breaker of plastic casing that specific embodiment of the present invention provides
Structure schematic diagram.
In figure:
1, bimetal leaf；2, conductor is connected；20, connecting line；21, the second connection conductor；3, transition connecting plate；30, first

Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, the bimetal leaf that Fig. 1 is the breaker of plastic casing that specific embodiment of the present invention provides connects
The schematic perspective view of binding structure.
In the present embodiment, a kind of bimetal leaf connection structure of breaker of plastic casing includes bimetal leaf 1, connection 2 and of conductor
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.
Above embodiments only elaborate the basic principles and features of the present invention, and the utility model is not by above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes, these changes
Change and change is fallen within the scope of the claimed invention.The utility model requires protection scope is wanted by appended right
Ask book and its equivalent thereof.
