The resistance heating plate of manufactured different resistance values, the control of heat is realized using the resistance value of resistance heating plate, reaches indirect
Control the purpose of protector current overload.But the protector of this structure have the following deficiencies: in use i.e. due to
The resistance heating plate material for being able to satisfy batch production requirements is limited, and the resistance value span of storeroom is larger, leads to protector
Protection precision it is not high, protective current section span is also inconsistent, to reduce the timeliness and reliability of protector.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of protection span is small, protection precision is high, protect it is more timely,
Security performance is more reliable, and the built-in protector of the wider array of current overload of use scope.
In order to solve the above technical problems, the utility model uses the built-in protector of such a current overload, being used for will
Failure of current of the electric appliance in overcurrent overheat operating condition comprising the metal shell of bottom opening closes the gold of the outer casing bottom
Belong to bottom plate, equipped with moving contact and when reaching set temperature overturning, lower than set temperature when the thermal plate that resets, with the dynamic touching
The static contact and two binding posts of the corresponding arrangement of head；The upper end of two binding posts is each passed through the bottom plate and protrudes into institute
It states in the confined space that shell and bottom plate are constituted, the shaft of two binding posts is connect with the bottom plate insulated enclosure respectively, the electricity
Flow through that carry built-in protector further include two stationary plates made of metal plate, one end of each stationary plate is upper with binding post
End is fixedly connected, and the other end of each stationary plate is fixedly connected with static contact, is equipped with and is used with the plate between each stationary plate both ends
In the resistance value adjusting area for adjusting stationary plate resistance value.
As a kind of preferred embodiment of the utility model, the stationary plate is in step, and the resistance value adjusting area is
Along stationary plate width direction 1.8~4.8mm range.
As a kind of preferred embodiment of the utility model, the thickness of the stationary plate is in 0.4~1mm range.
As a kind of preferred embodiment of the utility model, the stationary plate be cold-rolled low carbon steel piece or alcu alloy film or
Person's copper and iron composite material sheet.
After adopting the above structure, the utility model has the following beneficial effects:
Since two stationary plates made of metal plate, one end of each stationary plate and binding post is arranged in the utility model
Upper end is fixedly connected, and the other end of each stationary plate is fixedly connected with static contact, is equipped with the plate between each stationary plate both ends
It, therefore, can be according to the overcurrent protection value of different electric appliances when implementing for adjusting the resistance value adjusting area of stationary plate resistance value
By accurately adjusting the resistance value adjusting area of stationary plate, the calorific value of stationary plate is made accurately to correspond to overcurrent protection required for electric appliance
Value, to reach when electric appliance overcurrent overheat, can quickly shut off power supply in time, the purpose for preventing it from damaging.
The stationary plate of the utility model not only acts as fixed static contact effect, and also acts as auxiliary heat effect.
The utility model protects span small, and protection precision is high, and protection is more timely, and security performance is more reliable, and use scope is more
Extensively.
