One end of piece is welded with conducting wire welding locating detent, and conducting wire is connect by conducting wire welding locating detent with static contact, static contact it is another
End is equipped with stationary contact, and in same vertical line, movable contact is welded in one end of the spring leaf for movable contact and stationary contact, the other end with
Movable contact spring welding, and spring leaf is located at the top of bimetallic element, the end of the movable contact spring is welded with conducting wire welding locating detent,
Conducting wire welds locating detent by conducting wire and connect with movable contact spring, and the rear portion of the shell is equipped with sealant, and sealant carries out shell
Seal operation.
Preferably, the bimetallic element is equipped with location hole, and bimetallic element is that groove surface (high expansion face) makes downwards
Make normally closed product.
Preferably, the static contact, movable contact spring, fixing seat are placed in injection processing in plastic mould simultaneously and form fixing seat group
Part.
Compared with prior art, the utility model has the advantage that the utility model is designed reasonably, because in its shell
Bottom is equipped with felt pad, and shell can select metal material, and insulating materials also may be selected, and washability is good；Bimetallic element sense
The movable contact and stationary contact disconnection made on spring leaf, protected electric component main circuit are inverted when by prefabricated temperature rapidly
It disconnects rapidly and avoids damaging or connect output alarm signal, when temperature drops to the reset temperature of bimetallic element, double gold
Belong to element and restore overturning, the movable contact and stationary contact of micro sealing formula responsive to temperature type thermal protector are closed, and restore normal again
Working condition.
