Stationary contact closure on plate, shell and bottom plate are arranged in insulating boot body.During work, when electric appliance rises to temperature because of fever
During the operating temperature of protector, shell is heated and is conducted to bimetal leaf, and bimetal leaf, which is heated, to be produced internal stress and act rapidly,
Push open movable contact leave stationary contact and disconnecting circuit, play a protective role so as to cut off appliances power source.When protected electric appliance temperature
When degree drops to the specified reset temperature value of protector, bimetal leaf returns to original state dynamic and static contact closure, and electric appliance recovers
Normal work.In above-mentioned protector, the heat in double gold shoe is conducted by shell, because by shell product, heat conduction system
The influence of number and environment, often leads to bimetal leaf and is heated the slow movement or inconsistency of power-off, so as to reduce to electric appliance
Protecting effect.Simultaneously as the contact that movable contact contradicts with stationary contact is point contact, stability is poor, also have impact on bimetallic
Piece is heated the slow movement or inconsistency of power-off.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of thermal protector, which can improve double gold
Belong to piece to be heated the agility and stability of de-energizing actions, be effectively protected electric appliance.
In order to solve the above-mentioned technical problem, a kind of thermal protector of the utility model, containing shell, bimetal leaf, stationary contact,
Bottom plate, junction block one and junction block two, are equipped with insulating paper between bottom plate and shell, one end of bimetal leaf is arranged on by rivet
In shell, the other end of double gold shoe is equipped with movable contact, the movable contact and be arranged on bottom plate that double gold shoe other ends are equipped with
Stationary contact closes, and junction block one is connected with shell, and shell and bottom plate are arranged in insulating boot body, also has bridge-type electric heating piece, described
Bottom plate is Split type structure, and bottom plate includes left plate and right panel, and spacing, the junction block two and bottom plate are left between left plate and right panel
Left plate is connected, and stationary contact is arranged on the right panel of the bottom plate, and the both ends of bridge-type electric heating piece are separately positioned on a left side for the bottom plate
On plate and right panel；The movable contact is made of the packet structure of bottom and the contact of butt side's cone, during the stationary contact is
Packet structure of the centre equipped with V-groove, the V-groove and the contact of butt side's cone match.
The bridge-type electric heating piece is inverted U-shaped, and the top of the bridge-type electric heating piece is opposite with the middle part of double golden shoe
Should.
In above-mentioned thermal protector, due to being connected with bridge-type electric heating piece on the bottom plate of Split type structure, when working, bridge
The heat that formula electric heating piece is sent directly is radiated on bimetal leaf, is heated the agilitys of de-energizing actions so as to improve bimetal leaf
And stability, it is effectively protected electric appliance；Simultaneously because the contact of butt side's cone of movable contact and stationary contact center
V-groove match, contact of the movable contact with stationary contact contact for face, and stability is good, therefore contributes to bimetal leaf to be heated power-off
The agility and stability of action, are effectively protected electric appliance.
