211 materials are the solution of 220-270 degree fusing points, and one end lower plane is useful for assembly fusing 308 circular hole 601 of spring, among main body
Part has the pole 301 on a circular hole and the holder 210 to coordinate, under the action of fusing spring 308 so that fusing bar
211 as seesaw, 301 tilting of pole on holder 210, and the salient point 209 to fuse on bar 211 is then higher by brandreth 401,
For being contacted with heater element 601.
In a particular embodiment, Fig. 7 is dry combustion method non-automatic-reset protector assembly heater element schematic diagram, the non-runback of dry combustion method
After position protector is assemblied in heater element 601, the salient point 209 to fuse on bar 211 allows fusing after the plane of contact heating element
One end 602 of bar 211 is suspended on the poles N conductive sheet 212 so that at one group of contact on the poles N conductive sheet 212 and the poles N fixed frame 213
In normally off, after dry combustion method non-automatic-reset protector is put into lower seat 501, make heater element 601 in anhydrous dry combustion method,
So that the constant temperature of heater element 601 increases, in the case of normal, heater element 601 is at the temperature for reaching certain, assembly
After 402 self-deformation of bimetal leaf on brandreth 401, by porcelain stick 204 on the poles L conductive sheet 201 contact 304 and the poles L
Contact 305 on fixed frame 205 detaches, after the gap of 203 lower plane of the poles L conductive sheet 201 and porcelain stick frame becomes larger, self-locking spring
202 are caught in gap so that the contact 305 on 201 contact 304 of the poles L conductive sheet and the poles L fixed frame 205 is in separation shape always
State, prevent contact 305 on the contact 304 and the poles L fixed frame 205 on the poles L conductive sheet 201 after the reset of bimetal leaf 402 again
It is secondary to be connected, play the role of cutting off self-lock, and after protector is only taken out lower seat 501, in the effect of fore-set spring 307
Under, fore-set 206 is pushed, the inclined-plane 306 of fore-set 206 is made to act on self-locking spring 202, self-locking spring 202 is released the poles L and is led
Gap between electric piece 201 and the poles L fixed frame 205 so that on the contact 304 and the poles L fixed frame 205 on the poles L conductive sheet 201
Contact 305 is connected again, plays the role of reset, this is protected again for first, if above-mentioned 402 failure of situation bimetal leaf
In the case of, the temperature of heater element 601 can lasting raising again, since the salient point 209 of fusing bar 211 is to withstand on heater element
On 601 surfaces, when reaching the melting temperature of fusing bar 211, after the fusing of salient point 209 to fuse on bar 211, in fusing spring
Under the action of 308, pole 301 of the fusing bar 211 on holder 210 is allowed to rotate so as to be pressed in N under one end 602 of fusing bar 211
On pole conductive sheet 212, the contact 302 on the contact 303 and the poles N fixed frame 213 on the poles N conductive sheet 212 is detached, power-off is played
The effect of protection, this is protected again for second.
