Technical field
It the utility model is related to a kind of temperature protector, more particularly to a kind of bimetallic temperature protector.
Background technology
Bimetallic temperature protector is widely used in the temperature control of the home electrical heaters such as transformer, motor and similar electrical equipment
System and protection, it can experience and follow the change of environment temperature, and in the cut-out of default temperature spot execution circuit, a control
And defencive function.A kind of existing bimetallic temperature protector, contains shell, bimetal leaf, stationary contact, bottom plate and junction block one
With junction block 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, double
One end of sheet metal is arranged in shell by rivet, and the other end of double golden shoe is provided with movable contact, and double golden shoe other ends are set
Some movable contacts contradict 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, when
When electrical equipment makes the temperature rise to the operating temperature of temperature protector because of heating, shell is heated and is conducted to bimetal leaf, double gold
Category piece is heated to be produced internal stress and acts rapidly, is pushed movable contact open and is left stationary contact and disconnecting circuit, so as to cut off appliances power source
Play a protective role.When protected electrical equipment temperature drops to the specified reset temperature value of temperature protector, bimetal leaf is extensive
The dynamic and static contact closure of original state is arrived again, and electrical equipment recovers normal work.In said temperature protector, the heat in double golden shoe
Amount is conducted by shell, because being influenceed by shell product, thermal conductivity factor and environment, often leads to the heated power-off of bimetal leaf
Slow movement or inconsistency, so as to reduce the protecting effect to electrical equipment.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bimetallic temperature protector, the bimetal leaf temperature
Degree protector 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 bimetallic temperature protector of the utility model, contains shell, bimetallic
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 closure on bottom plate, junction block one are connected with shell, and shell and bottom plate are arranged in insulating boot body, also bridge-type electricity
Backing, the bottom plate are Split type structure, and bottom plate includes left plate and right panel, spacing, the junction block are left between left plate and right panel
Two are connected with the left plate of bottom plate, 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 institute
State in the left plate and right panel of bottom plate.
The bridge-type electric heating piece is inverted U-shaped, and the top of the bridge-type electric heating piece is relative with the middle part of double golden shoe
Should.
The movable contact and stationary contact are packet structure.
In above-mentioned bimetallic temperature protector, due to being connected with bridge-type electric heating piece on the bottom plate of Split type structure, because
During this work, the heat that bridge-type electric heating piece is sent directly is radiated on bimetal leaf, so as to improve the heated power-off of bimetal leaf
The agility and stability of action, are effectively protected electrical equipment.
