It is arranged above bottom plate, the bottom plate is respectively arranged with stationary contact in heater strip both sides, it is characterised in that：The bottom plate is equipped with
The opposite boss set up, the heater strip both ends are connected on boss, and the one side of the shell towards heater strip connects
There is fixed plate, the fixed plate both sides are connected to bimetal leaf, and the movable contact is arranged at one end of bimetal leaf and can
Separating-closing type is arranged at the top of stationary contact, and the shell is arc-shaped, and both ends are described to insert respectively by plug connector and bottom plate grafting
Fitting one end is cage connection portion, has and is connected with same radian at cage connection, the plug connector other end for bottom plate
Portion, the chassis connection sections are equipped with bottom plate link slot, and the bottom plate is plugged in bottom plate link slot.
A kind of above-mentioned overheat protector can be further arranged to：The shell is with being equipped with connection in the middle part of plug connector junction
Convex block, the connection convex block both sides are respectively equipped with connecting groove, the cage connection portion of the plug connector be equipped with be connected convex block and
The link block that connecting groove shape matches, the cage connection portion are connected to shell by link block.
A kind of above-mentioned overheat protector can be further arranged to：The bottom plate both sides are respectively equipped with matches somebody with somebody with bottom plate link slot
The riveting ear of conjunction, the riveting ear are respectively clamped into corresponding bottom plate link slot.
Using above-mentioned technical proposal, the utility model structure order is easily achieved, using dual movable contact and stationary contact sense
Answer circuit abnormality, when current surge, the point influenza of heater strip and double metal piece should can more rapidly execution circuit cut-out, from
And the function of protection circuit is played, and the shell both sides in this programme are equipped with groove, the riveting ear of bottom plate can be caught in by when assembling
In corresponding limiting groove, so as to enhance the bonding strength between shell and bottom plate.
The utility model is described in further detail with reference to the accompanying drawings and examples.
