2, this temperature sensor insulation excellent, moistureproof moisture-proof, safe and reliable.Adopt that the water-heater efficiency of this temperature sensor is high, energy consumption is low, reach that the time of design temperature is short, steady temperature fluctuation is little, antijamming capability strong, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of temperature sensor in utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
In figure, protecting sheathing 1, circuit board 2, epoxy resin 3, sensing element 4, stilt 5, pad 6, heat-shrinkable T bush 7, wire 8, connector 9, connection terminal 10.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details.
See accompanying drawing 1 and Fig. 2, for the temperature sensor of electric kettle, comprise protecting sheathing 1, sensing element 4, circuit board 2, wire 8, heat-shrinkable T bush 7, connection terminal 10 and connector 9; Protecting sheathing is monoblock type copper shell, and described monoblock type copper shell carries out nickel plating surface process, and the top of described protecting sheathing 1 is thin wall tubule shape, and middle part is standard retaining thread, and afterbody is regular hexagon; Described sensing element 4 to be arranged in protecting sheathing 1 and to be positioned at the top of protecting sheathing 1; sensing element 4 adopts SMD to encapsulate the front end being fixed on circuit board 2; circuit board 2 is also provided with stilt 5 and pad 6; the width of circuit board is corresponding with the diameter on protecting sheathing top; to guarantee the stability of sensing element; one end of wire 8 is connected with sensing element 4; the other end of wire 8 is successively through heat-shrinkable T bush and electric wire connecting junction; then be connected with connection terminal 10, described connection terminal 10 is connected with connector 9.Pad 6 is positioned at the end of circuit board 2, and for welding lead 8, be fixed by the section lead be positioned on circuit board 2 by the mode being welded on pad 6, lead material is PVC wire rod, PVC can also be adopted two and wire rod.
As optimization, sensing element 4 adopts epoxy resin to carry out insulating and encapsulating.Thus it is the insulation that this temperature sensor has just been had and moistureproof moisture resistance properties, safe and reliable.In order to the accuracy of detection improving temperature sensor can also fill heat conduction matter in protecting sheathing, this heat-conducting medium preferably adopts the heat-conducting silicone grease that performance is higher.
Stilt 5 is nonmetal stilt; nonmetallic heat conductive performance is relatively poor; all smaller on the impact of sensor accuracy class and reaction velocity; by the structural design of nonmetal stilt protection sensor; during installation, welding can be adopted, boring is fixing or adopt welding or hole fixing or be fixed on circuit board with high strength binder.Rubber thing can be selected to support, and with boring, fixing or high strength binder fixed plastics stilt supports, and ceramic support supports, and welding or high strength binder can be adopted to fix.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
