Brief description of the drawings
Fig. 1 is the structure diagram of the utility model NTC temperature sensors；
Fig. 2 is the structure diagram of the casing assembly in the utility model.
Embodiment
It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The embodiment of the utility model is described below in detail, the example of embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or has the function of same or like element.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the utility model, and it is not intended that limit to the utility model
System.
As shown in Figure 1 to Figure 2, the NTC temperature sensors of the utility model, including casing assembly 1, thermistor 2, silica gel
Conducting wire 3 and insulation adhesive layer 4, casing assembly 1 include plastic casing 10 connected horizontally and metal blind pipe 11,10 He of plastic casing
Metal blind pipe 11 is fixedly connected by high-temperature injection.Thermistor 2 and the termination of silica gel conducting wire 3 are welded and fixed, thermistor 2
The exterior exposed part with silica gel conducting wire 3 scribbles marine glue.The thermistor 2 and silica gel conducting wire 3 for scribbling marine glue pass through insulation
Adhesive layer 4 is potted in casing assembly 1, and the material of insulation adhesive layer 4 is epoxy resin.
Thermistor 2 is single-ended glass packaged thermosensitive resistor, including NTC ceramic substrate 20, the NTC ceramic substrate 20 are close
It is encapsulated in vitreum 21.
The right end of metal blind pipe 11 is vertically installed with connecting portion 110, and 110 shape of connecting portion is corrugated.Metal blind pipe 11
Right end be fixedly connected by connecting portion 110 with the left end high-temperature injection of plastic casing 10.
The material of metal blind pipe 11 is copper, and the wall thickness of metal blind pipe 11 is 0.10-0.25mm.
The material of plastic casing 10 adds glass for nylon, relative to the stainless of bullet-shaped temperature sensor in the prior art
Steel metal shell, epoxy resin add the caking property of glass more preferable than the caking property of epoxy resin and stainless steel with nylon, so that this
The leakproofness and water proofing property of utility model are more preferably.
On reaction time, the bullet-shaped temperature sensor of the prior art, stainless steel metal shell wall thickness is 0.2-
0.3mm, wall thickness, quality and thermosol are all higher than the utility model.Since sensor is warm from a temperature environment into another
Spend under environment, reach thermally equilibrated speed and be inversely proportional with hot melt, hot melt is bigger, and the heat of absorption is more, when reaching thermally equilibrated
Between it is longer；It is otherwise shorter.Wall thickness is thinner, and the reaction time is shorter.In addition, on heat-transfer effect, the reaction speed of copper will be faster than stainless
Steel.The above, illustrates the NTC temperature sensors of the utility model compared with prior art, reaction speed is faster.
It can be seen from the above that the NTC temperature sensors of the utility model, it is simple in structure, it can be achieved that water proofing property more preferably, reaction speed
Faster, using more stable technique effect.The NTC temperature sensors of the utility model can be widely applied to water heater, intelligence
The fields such as closestool, bathroom, biological hatching, incubator, flowmeter.
The above, is only the preferred embodiment of the utility model, is not intended to limit the protection of the utility model
Scope.
