Standby Thermal protection, prevents part from reaching the temperature of danger under fault conditions.Thermal Cutoffs can substantially be divided by temperature sensing material
For alloy-type temperature fuse and organic type Thermal Cutoffs, existing market is mainly based on alloy-type temperature fuse.
One section of fusible alloy silk is connected between alloy-type temperature fuse two pins, special resin is coated with fusible alloy
Silk, electric current can flow to another pin from a pin, when Thermal Cutoffs environment temperature rises to its operating temperature,
Its fusible alloy melts and under surface tension effects and under special resin help, shrinks glomeration and is attached to two pins end
End.So circuit is by permanent shut-down.
With the popularization of various high-power household electrical appliance, it is desirable to Thermal Cutoffs rated current more and more higher, organic matter
Although type Thermal Cutoffs can provide higher rated current, but intolerant to surge, in the case where there is big surge impact, fuse can
Easily it is welded between moving contact and starlike reed, loses fuse and use effect.Existing alloy-type temperature fuse master
Apply in low-power product, with the raising of rated current, B alloy wire diameter needs corresponding increase, on current fluxing agent surface
Under tension, alloy fusing difficulty is increased, and the potential safety hazard such as electric arc easily occurs, burn, be failure to actuate.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction used in Thermal Cutoffs long term high temperature
During, the fluxing agent of inner molten is not permeable to be spilt, it is to avoid the Double alloy piece Thermal Cutoffs that fuse evening breaks.
To solve the above problems, the utility model is adopted the following technical scheme that：
A kind of Double alloy piece Thermal Cutoffs, including plastic casing, the first plain conductor, the second plain conductor, fluxing agent,
Seal and welded between resin, the first alloy sheet and the second alloy sheet, the end of first plain conductor and the second plain conductor
The first alloy sheet and the second alloy sheet of the parallel low temperature fusible of two panels are provided with, four solder joints are crushed, first gold medal
Category wire and the welding ends of the second plain conductor stretch out a bit of, are filled with fluxing agent inside the plastic casing, and described the
The welding ends of one plain conductor and the second plain conductor is arranged in fluxing agent, and the port of export of the plastic casing, which is applied, is covered with envelope
Compacting is provided with groove at sealing resin on mouth resin, first plain conductor and the second plain conductor.
Preferably, minimum air line distance is more than 1.0mm between described two parallel the first alloy sheets and the second alloy sheet.
Preferably, first plain conductor and the plain conductor that the second plain conductor is cylindrical type, the first alloy sheet
On the plain conductor for being welded on two cylindrical types in parallel with the second alloy sheet.
Preferably, the sealing resin uses epoxy resin or silicones.
The utility model reasonable in design, up and down two pieces of flat low-temperature alloy pieces form temperature sensor, alloy sheet is put down
Row is welded on the plain conductor of two cylindrical types, and four solder joints are crushed and played a supportive role, often with plain conductor in solder joint
Root stretches out a bit of, and in coating sealing compound position press flute, safing electric clearance, two parallel alloy sheets
Between minimum air line distance have to be larger than 1.0mm；
Stretch out a bit of two plain conductor solder joint roots, when semi-finished product are inserted into outside the plastics filled with fluxing agent
During shell, alloy sheet below is unlikely to be directly adjacent to shell bottom, it is ensured that alloy sheet is coated completely by fluxing agent, with it is very big should
With value.
In plain conductor coating sealing compound position press flute, the sealing of increase sealing resin and metal pins, so
During Thermal Cutoffs long term high temperature use, the fluxing agent of inner molten is unlikely to leak out, it is to avoid fuse evening is disconnected
Even constantly situation occurs.
