Description
Technical field
It the utility model is related to a kind of temperature protector, more particularly to a kind of bimetal plate heat protector.
Background technology
Bimetal plate heat protector is widely used in the temperature control of the home electrical heaters such as transformer, motor and similar electrical equipment
And protection, it can experience and follow the change of environment temperature, and in the cut-out of default temperature spot execution circuit, rise control and
Defencive function.A kind of existing bimetal plate heat protector, containing shell, bimetal leaf, stationary contact, bottom plate and junction block one and connect
Line seat two.Insulating paper is provided between bottom plate and shell, junction block one is connected with bottom plate, and stationary contact is arranged on bottom plate, bimetallic
One end of piece is arranged in shell by rivet, and the other end of double golden shoe is provided with movable contact, what double golden shoe other ends were provided with
Movable contact contradicts to be closed with the stationary contact being arranged on bottom plate, and shell and bottom plate are arranged in insulating boot body.During work, work as electrical equipment
When the temperature is risen to the operating temperature of temperature protector because of heating, shell is heated and is conducted to bimetal leaf, bimetal leaf
It is heated to produce internal stress and act rapidly, push movable contact open and leave stationary contact and disconnecting circuit, played so as to cut off appliances power source
Protective effect.When protected electrical equipment temperature drops to the specified reset temperature value of temperature protector, bimetal leaf returns to
The dynamic and static contact closure of original state, electrical equipment recover normal work.Because the contact that movable contact is contradicted with stationary contact contacts for point,
Stability is poor, therefore often leads to the slow movement or inconsistency of the heated power-off of bimetal leaf, so as to reduce to electrical equipment
Protecting effect.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bimetal plate heat protector, and bimetal leaf heat is protected
Shield device can improve the agility and stability of the heated de-energizing actions of bimetal leaf, be effectively protected electrical equipment.
In order to solve the above-mentioned technical problem, a kind of bimetal plate heat protector of the utility model, shell, bimetallic are contained
Piece, stationary contact, bottom plate, junction block one and junction block two, are provided with insulating paper between bottom plate and shell, one end of bimetal leaf passes through
Rivet is arranged in shell, and the other end of double golden shoe is provided with movable contact, the movable contact and setting that double golden shoe other ends are provided with
Stationary contact on bottom plate is touched, and junction block one is connected with shell, and shell and bottom plate are arranged in insulating boot body, the movable contact
It is made up of the packet structure of bottom and the contact of butt side's cone, the stationary contact is provided with the packet knot of V-groove for center
Structure, the V-groove and the contact of butt side's cone match.
In above-mentioned bimetal plate heat protector, due to the contact and the V in stationary contact center of butt side's cone of movable contact
Type groove matches, and contact of the movable contact with stationary contact contacts for face, and stability is good, therefore improves the heated de-energizing actions of bimetal leaf
Agility and stability, be effectively protected electrical equipment.

Embodiment
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings：
As Figure 1-4, the utility model discloses a kind of bimetal plate heat protector, shell 1, bimetal leaf are contained
4th, stationary contact 5, bottom plate 3, junction block 1 and junction block 28.Insulating paper 7 is provided between bottom plate 3 and shell 1.Bimetal leaf 4
One end is arranged in shell 1 by rivet 2, and the other end of double golden shoe 4 is provided with movable contact 6, what double golden other ends of shoe 4 were provided with
Movable contact 6 touches with the stationary contact 5 being arranged on bottom plate 3.Junction block 1 is connected with shell 1.Shell 1 and bottom plate 3 are arranged on absolutely
In edge cover body.The movable contact 6 is made up of the packet structure of bottom and the contact 10 of butt side's cone, and the stationary contact 5 is
Center is provided with the packet structure of V-groove 11, and the V-groove 11 and the contact 10 of butt side's cone match.
In above-mentioned bimetal plate heat protector, contact 10 and the center of stationary contact 5 due to butt side's cone of movable contact 6
V-groove 11 match, the contact with stationary contact 5 of movable contact 6 contacts for face, and stability is good, therefore improves bimetal leaf and be heated
The agility and stability of de-energizing actions, are effectively protected electrical equipment.
Above-described embodiment, the purpose of this utility model, technical scheme and beneficial effect are entered
One step describes in detail, should be understood that and the foregoing is only specific embodiment of the present utility model, is not used to limit
The utility model processed, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements done etc.,
