Embodiment
A following embodiment who describes the used for automobile air conditioning evaporator temperature sensor of the utility model with reference to figure 1-Fig. 4 in detail; Present embodiment mainly includes a housing and the sensing unit-thermistor that is arranged in the said housing, and said housing is the integral structure of injection mo(u)lding outside said thermistor.As shown in the figure; The end of said housing is that an anticollision environmental protection guard shield 11, middle part are that mechanical connecting structure 12, afterbody are electric mortiser access node structure 13; Said sensing circuit includes thermistor 21, high temperature wire 22 and contact pin 23; Said thermistor 21 is arranged in the said anticollision environmental protection guard shield 11, and said contact pin 23 is plugged on the said electric mortiser access node structure 13, and said thermistor 21 is electrically connected with said contact pin 23 through the high temperature wire 22 that passes from said mechanical connecting structure 12 inside.
During concrete the realization, said thermistor 21 adopts constant thermistor between small sizes hour, and like NTC type thermistor, the NTC thermistor is formed by NTC chip and epoxy packages material cured.This sealing entity structure that forms through the heat-conduction epoxy resin encapsulation can guarantee insulating requirements under the moisture-proof environment, can guarantee good heat conductivity again.And said high temperature wire 22 is a high temperature PFA lead, and 23 welding are connected as a single entity said NTC thermistor 21 with contact pin with high temperature PFA lead 22.
During concrete the realization, the side of said anticollision environmental protection guard shield 11 is set to open perforation structure, and NTC type thermistor 21 places the middle position in the said anticollision environmental protection guard shield 11.The effect of anticollision environmental protection guard shield 11 is when preventing the sensor assembling small size thermistor to be caused damage; And make the wind of blowing over also in time to be passed to ECU by thermistor 11 collection identifications rapidly from condenser core.
Said mechanical connecting structure 12 includes a connecting rod 121; The both sides of said connecting rod 121 are provided with installs buckle 122; And said high temperature wire 22 is arranged in the said connecting rod 121, and also is provided with error protection structure 123 at said connecting rod 121 near an end of said electric mortiser access node structure 12.During installation, behind the mounting hole of installing on the buckle 122 insertion HVAC housings, its end can automatically spring open, and prevents that sensor from coming off.
In addition; Some air vents 124 also can be set on the connecting rod 13, and its effect is to weaken windage, when condenser core is blown over next wind through plastic bar; Partly wind can pass through the windage mouth; Can guarantee like this small size NTC resistance detection to be one at the uniform velocity, uniform steady temperature, thus it is unstable and cause the sensor sensing wrong temperature and transmit the possibility of rub-out signal to reduce Yin Wendu.
Said electric mortiser access node structure 13 includes a base 131 and is arranged on the plug receptacle 132 on the said base 131; Said contact pin 23 passes said base 131 and extends in the said plug receptacle 132, and respectively is provided with on the two side of said plug receptacle 132 on a jointing holes 133, the antetheca and then is provided with twice slot 134.The effect of jointing holes 113 and slot 134 is to guarantee that plug receptacle 132 can stably be seated with interfacing part, prevents that interfacing part from coming off under more abominable transportation condition, causes product failure.
In addition, in the present embodiment, between said mechanical connecting structure 12 and electric mortiser access node structure 13, a packing washer 3 can be set also, its effect is the effect that reaches damping and sealing, avoids product loosening or come off when road conditions are bad.
The utility model compared with prior art has the following advantages:
Thermistor is positioned at working of plastics anticollision environmental protection guard shield, and volume is little, and is better to temperature sensitivity; Shell structure and air-conditioner housing that incorporate band is installed buckle are prone to assembling and dismounting, can on the HVAC housing, once be seated, and the rubber washer that cooperates electricity to patch structure front end has reached good damping effect; And three via design on the connecting rod; Make that resistance was littler when air-conditioning was blown over next wind through sensor, the wind band is more even.
The above is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.
