The schematic diagram of double protection thermal cut-off when first time disconnects that Fig. 2 provides for the present invention and invention;
The schematic diagram of double protection thermal cut-off when second time disconnects that Fig. 3 provides for the present invention and invention.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Consult shown in Fig. 1 to Fig. 3, a kind of thermal cut-off of organic alloy type double protection, comprise metal shell 9, and the earthenware 3 be arranged on inside metal shell 9, starlike reed 5, disk 6, bulky spring 7, organic substance 8, and the hairspring 4 be enclosed within outside earthenware 3 one end, and be fixed on the outer epoxy resin 2 of metal shell 9 one end, and the outer lead 1 be fixed in outer epoxy resin 2, and the special fat 11 be fixed in earthenware 3, and the alloy 12 be fixed in special fat 11, and the lead 14 to be connected with special fat 11, and be arranged on lead 14 periphery, and be positioned at the epoxy resin 13 of earthenware 3 end, and the wire 10 be fixed on earthenware 3 one end.
The end of described lead 14 and the inconsistent setting of starlike reed 5 one side surface.
Described disk 6 has two panels, is separately positioned on the left and right sides of bulky spring 7, and the disk 6 in left side and the inconsistent setting of starlike reed 5 opposite side, disk 6 and the inconsistent setting of organic substance 8 on right side.
Described earthenware 3 endoporus is alloy positioning and mounting structure, and outer circumferential end face is that metal shell 9 crimping is relatively fixing.
The fusing point of described alloy is higher than organic fusing point 5 DEG C-30 DEG C.
In the present embodiment, as shown in Figure 1, organic substance 8 is the first thermo-sensitive material, experiences temperature, and alloy 12 is the second thermo-sensitive material, experiences temperature; Special fat 11 is flux, shrink balling-up during melting aid alloy melted by heat, earthenware 3 endoporus is alloy location and installation, and outer face is that metal shell 9 crimping is fixed, bulky spring 7 and hairspring 4 mutually compress and carry out promoting starlike reed 5 and contact with lead 14, and organic substance 8 supports bulky spring;
Disk 6 (two panels) provides plane contact for bulky spring, outer epoxy resin 2 and interior epoxy resin 13 are for sealed ceramic body, current-carrying part is sequentially: outer lead 1, alloy 12, lead 14, starlike reed 5, metal shell 9, wire 10, when normality does not experience temperature, described current-carrying part one_to_one corresponding contact connects, and forms conducting loop.
As shown in Figure 2, when the temperature that double protection thermal cut-off is experienced meets or exceeds organic substance 8 melting temperature, thermal cut-off lead 14 is separated with starlike reed 5, and cut-off loop, realizes traditional Thermal protection for the first time; When the temperature that double protection thermal cut-off is experienced meets or exceeds organic substance 8 melting temperature, organic substance 8 is liquid or gaseous state by Solid State Transformation, bulky spring 7 loses support, start release, hairspring 4 starts to promote starlike reed 5 guiding line 10 direction and moves, be separated with lead 14, water conservancy diversion loop is cut off, so loop first time is cut-off.
As shown in Figure 3, when the temperature that double protection thermal cut-off is experienced meets or exceeds alloy 12 melting temperature, thermal cut-off outer lead 1 is separated with lead 14, and second time cut-off loop, realizes dual Thermal protection, stop the inefficacy of traditional Thermal protection;
When the temperature that double protection thermal cut-off is experienced meets or exceeds alloy 12 melting temperature, alloy 12 is liquid by Solid State Transformation, under the capillary fluxing action of special fat, alloy shrinkage glomeration is in outer lead 1 and lead 14 two ends, water conservancy diversion loop is cut off, so loop second time is cut-off;
When the constant temperature that double protection thermal cut-off is experienced, organic substance 8 that is liquid or gaseous state there will be charing, the state of heavy first conducting, the loop that such first time cuts off is resumed conducting, but the loop that the second time of alloy melting is cut off, be sealed in earthenware, the loop protecting second time cut-out is not destroyed, thus realize bulk loop and be still in dissengaged positions, stop the inefficacy of traditional Thermal protection, realize dual Thermal protection;
When double protection thermal cut-off is installed; if metal shell 9 is squeezed; starlike reed 5 will clamping stagnation in inner walls, namely pipe temperature allows organic substance 8 change liquid or gaseous state into, and bulky spring 7 discharges; hairspring 4 also cannot promote starlike reed 5; cut-off loop will lose efficacy for the first time, but the loop that the second time of alloy melting is cut off, the installation of having stopped traditional Thermal protection was lost efficacy; existing Thermal protection, proterctive equipment safety.
The standardized element that the present invention uses all can be commercially, shaped piece all can carry out customized according to specification with the record of accompanying drawing, the concrete connected mode of each part all adopts the conventional means such as bolt, rivet, welding ripe in prior art, machinery, part and equipment all adopt in prior art, conventional model, add that circuit connects and adopt connected mode conventional in prior art, be not described in detail in this.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
