It is silver paste conducting surface on the left conducting surface and right conducting surface of the PTC thermistor.
In above-mentioned New temperature protector, due to being connected with bridge-type electric heating piece and PTC heat on the bottom plate of Split type structure
Quick resistance, therefore when working, electrical heating and the shell of New temperature protector is heated and be conducted to bimetal leaf, while bridge
The heat that formula electric heating piece is sent directly is radiated on bimetal leaf, and PTC thermistor will not produce high temperature, when bimetal leaf by
When heat reaches rated function temperature, bimetal leaf, which is heated, to be produced internal stress and acts rapidly, push open movable contact leave 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 double gold
Belong on piece, the movable contact on bimetal leaf and the stationary contact being arranged on bottom plate is always maintained at off-state, so as to cut off electricity
Device power supply plays a protective role.Simultaneously because the contact of butt side's cone of movable contact and the V-groove in stationary contact center match, move
Contact of the contact with stationary contact contacts for face, and stability is good, thus contribute to bimetal leaf be heated de-energizing actions agility and
Stability, is effectively protected electric appliance.

Embodiment
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figs 1-4, the utility model discloses a kind of New temperature protector, shell 3, bimetal leaf 6, quiet is contained
Contact 8, bottom plate, junction block 1 and junction block 21.Insulating paper 9 is equipped between bottom plate and shell 3, one end of bimetal leaf 6 leads to
Cross rivet 4 to be arranged in shell 3, the other end of double gold shoe 6 is equipped with movable contact 7, the movable contact that double gold 6 other ends of shoe are equipped with
8 close with the stationary contact 8 being arranged on bottom plate, and junction block 1 is connected with shell.A kind of above-mentioned New temperature protector also has
Bridge-type electric heating piece 5, PTC thermistor 13 and steel card 12.The bottom plate is Split type structure, and bottom plate includes left plate 2 and right panel 10, left
Spacing 11 is left between plate 2 and right panel 10.The junction block 21 is connected with the left plate 2 of bottom plate, and stationary contact 8 is arranged on the bottom
On the right panel 10 of plate.The both ends of bridge-type electric heating piece 5 are separately positioned in the left plate 2 and right panel 10 of the bottom plate, bridge-type electric heating piece 5
It is corresponding with the middle part of double golden shoe 6 for inverted U-shaped, the top of the bridge-type electric heating piece 5；A left side for PTC thermistor 13
Conducting surface and right conducting surface is fixed on by the steel card 12 on bottom plate and the left conducting surface of PTC thermistor 13 and right conduction
Face is connected with the left plate 2 and right panel 10 of bottom plate respectively.The shell 3, bottom plate and steel card 12 are arranged in insulating boot body.It is described dynamic
Contact 7 is made of the packet structure of bottom and the contact 15 of butt side's cone, and the stationary contact 8 is equipped with V-groove 16 for center
