Abstract
The utility model relates to a PTC temperature sensor part which is arranged at the heating position of mechanical and electrical apparatus device to implement fixed-point temperature control or temperature alarming control, the temperature sensing chip head connected by electric connection line is mainly a PTC thermistor chip which is encapsulated by silicone resin encapsulation glue, and segregation four fluorine casing is contractively coated outside. The technology has the advantage of wide range of high temperature proof, being capable of working under various working environment, high reliability, etc.
Description
The utility model relates to the key structure parts that prevent machinery, electrical installation damage or influence functional reliability because of overheated, and be arranged at PTC temperature sensor its heating position, that be convenient to implement set point temperature control or temperature alarming control.
The structure of present temperature control PTC sensor is the microminiature PTC thermistor that electric connection line connects, its thermistor and electrical connector part are tightly wrapped up by the electro-insulating rubber pipe, the part of electro-insulating rubber parcel has just formed the sensing core print of temperature sensor signal, there are a lot of technological deficiencies in the product of this structure: its transducing part is only wrapped up by gum sleeve, its part conductivity is directly to be contacted with environment space, when ambient humidity has bigger variation, can have a strong impact on its sensing work, the humidity resistance extreme difference; In addition, its sleeve pipe is an elastomeric material, its convergent force is little, resistance to elevated temperatures is poor, often be in hot environment, its digestion time is short, is difficult to make the state of tightening of core print long term maintenance electric connection line, it is very little to make the electric connecting terminal of core print bear pulling force, makes root that electric connection line breaks away from or is connected with solder joint because of warpages, fracture lose the effect of temperature control sensing in a large number easily; Once more, the maximum temperature that elastomeric material can bear between 150-180 ℃, its temperature control narrow range.In sum, original temperature control PTC sensor technology has limited its range of application greatly because each side is former thereby cause functional reliability poor.
Goal of the invention of the present utility model is to provide a kind of temperature control PTC sensor that improves its functional reliability by improving its technical pattern, enlarges its temperature control scope.
The utility model patent is applied for the temperature control PTC sensor protected; it includes the temperature sensing core print that electric connection line connects; the major technique characteristics of the technical program are that the sensing core print is the PTC thermistor chip; the chip both sides connect electric connection line; chip and its electrical connections are sealed by the silicones encapsulating compound, and its outer shrink pack is wrapped with poly-partially tetrafluoro sleeve pipe.
The temperature control PTC sensor of present patent application has adopted silicones electricity sealing and the poly-partially tetrafluoro sleeve pipe with resistance to elevated temperatures, PTC thermistor and electric connecting terminal thereof are all wrapped up with external insulation sealing and deflation, its humidity resistance and resistance to elevated temperatures have been improved greatly, the range of application and the field of this temperature-control senser have been enlarged, and poly-partially tetrafluoro heat-shrink tube not only has the good temperature resistance energy, and has a good shrinkage, can make the electrical connections of core print more firm, thus greatly its functional reliability.
Describe the utility model technology contents in detail below in conjunction with the accompanying drawing illustrated embodiment.
Fig. 1 is the external structure synoptic diagram of this temperature control PTC sensor
Fig. 2 is the sectional structure synoptic diagram of sensing core print part.
Temperature control PTC sensor of the present utility model, include sensing core print 1 and the transducing signal of sensing core print is sent into the electric connection line 2 of signal processing circuit, wherein the structure of sensing core print 1 is the line end welding of microminiature PTC thermistor chip 10 both sides and electric connection line 2, seal by the silicones encapsulating compound around the soldered joint of PTC chip and electric connection line, form an encapsulated layer 11, change especially humidity variation to the harmful effect of core print sensing work to stop working environment, the link part that reaches electric connection line outside the encapsulated layer 11 tightens parcel by poly-partially tetrafluoro heat-shrinkable T bush 12, this heat-shrink tube 12 can the fastening clamp electric connection line link, the pulling force that electrical connector is born reduces greatly, and bear by connecting line, improved the connection reliability of welding position greatly.
