Bimetal leaf returns to original state dynamic and static contact closure, and electric appliance recovers normal work.In above-mentioned temperature protector, double gold
Heat in shoe is conducted by shell, because being influenced by shell product, thermal conductivity factor and environment, often leads to bimetal leaf
The slow movement or inconsistency of heated power-off, so as to reduce the protecting effect to electric appliance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of temperature protector, which can improve
Bimetal leaf is heated the agility and stability of de-energizing actions, is effectively protected electric appliance.
In order to solve the above-mentioned technical problem, a kind of temperature protector of the utility model, contains shell, bimetal leaf, stationary contact
Point, 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 set by rivet
Put inside the 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
On stationary contact closure, junction block one is connected with shell, and also bridge-type electric heating piece, PTC thermistor and steel card, the bottom plate are
Split type structure, bottom plate include left plate and right panel, and spacing, the left plate phase of the junction block two and bottom plate are left between left plate and right panel
Even, 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 left plate and the right side of the bottom plate
On plate, bridge-type electric heating piece is inverted U-shaped, and the top of the bridge-type electric heating piece is corresponding with the middle part of double golden shoe；PTC heat
The left conducting surface and right conducting surface of quick resistance by the steel fix be scheduled on bottom plate and the left conducting surface of PTC thermistor and
Right conducting surface is connected with the left plate and right panel of bottom plate respectively, and the shell, bottom plate and steel card are arranged in insulating boot body.
The movable contact and stationary contact are packet structure.
Notch is equipped between the left conducting surface and right conducting surface of the PTC thermistor.
It is silver paste conducting surface on the left conducting surface and right conducting surface of the PTC thermistor.
In above-mentioned temperature protector, due to being connected with bridge-type electric heating piece and PTC temperature-sensitives electricity on the bottom plate of Split type structure
Resistance, therefore when working, electrical heating and the shell of temperature protector is heated and be conducted to bimetal leaf, while bridge-type electric heating piece
The heat sent is directly radiated on bimetal leaf, and PTC thermistor will not produce high temperature, reaches volume when bimetal leaf is heated
When determining operating temperature, bimetal leaf, which is heated, to be produced internal stress and acts rapidly, is pushed movable contact open and is left stationary contact and disconnecting circuit；
At this moment PTC thermistor resistance value, which becomes larger, produces high temperature, and the heat sent with bridge-type electric heating piece is together radiated on bimetal leaf, makes
Movable contact on bimetal leaf is always maintained at off-state with the stationary contact being arranged on bottom plate, is played so as to cut off appliances power source
Protective effect.From the aforegoing it can be seen that above-mentioned temperature protector not only increase bimetal leaf be heated de-energizing actions agility and
Stability, and electric appliance is obtained significantly more efficient protection.
