The shell fragment of temperature controller.
Utility model content
In order to solve the problems, such as the shell fragment and poor contact of contacts in existing auto-reset type bi-metal temperature controller, this
The purpose of utility model is to provide a kind of shell fragment for auto-reset type bi-metal temperature controller, has simple in construction, section
Cost-saving, with contact it is more close the advantages of.
The utility model provides following technical scheme：
A kind of shell fragment for auto-reset type bi-metal temperature controller, including the stator of shell fragment and V-arrangement, the bullet
Piece is fixedly connected with the stator, and the shell fragment includes shrapnel part, rake and the fixed part to connect successively, the shell fragment
Portion, the rake and the fixed part are integrally formed, and the shrapnel part is provided with square stationary contact and lobes, institute
State stationary contact to be fixedly connected in the shrapnel part, the fixed part is provided with the first circular hole, and the stator includes the first square
Shape portion and the second rectangular portion, first rectangular portion and second rectangular portion are integrally formed, the fixed part and described first
Rectangular portion is fixedly connected.The square stationary contact contacts closer with the shrapnel part.
Preferably, first rectangular portion is provided with the second circular hole, second circular hole and the first Circularhole diameter phase
Together, the axis of second circular hole and first circular hole overlaps.The utility model passes through second circular hole and described first
Circular hole is riveted together with the pedestal in auto-reset type bi-metal temperature controller.
Preferably, second rectangular portion is provided with the 3rd circular hole.
Preferably, the connected mode of the stationary contact and the shrapnel part is welding.Material, existing company are more saved in welding
Connect mode for riveting, and the stationary contact be connected with the shrapnel part it is closer.
Preferably, the connected mode of the fixed part and first rectangular portion is welding.
Preferably, the material of the stationary contact is Agcdo.Agcdo is because contained cadmium oxide is under arcing
Occur acutely to decompose, evaporate and there is good anti-melting welding, resistance to arc erosion energy and low and stable contact resistance.Meanwhile
Agcdo also has good processing characteristics.
The beneficial effects of the utility model are：It is simple in construction；The connected mode of stationary contact and shrapnel part is welding, is saved into
This；Stationary contact is square, and stationary contact is connected closer with shrapnel part.
