Description

A kind of environment temperature sensor
Technical field
The utility model is related to temperature monitoring technique fields, are specifically a kind of environment temperature sensor.
Background technology
Environment temperature sensor is the device for measuring environment temperature outdoor in driving conditions.Existing environment temperature sensing Device, measurement temperature-responsive is slow, insensitive, judges that outdoor environment temperature is inaccurate, it is impossible to accurately provide a signal to automobile Urea tank control module, output temperature error ± 5 DEG C.In addition, it is also possible to be present with sensor internal short circuit under special circumstances Or short circuit causes sensor failure.Therefore, it is necessary to research and develop a kind of temperature sense environment temperature that is sensitive, accurate, being not easy short circuit Sensor.
Utility model content
The purpose of this utility model is that solving the problems mentioned above in the background art, a kind of temperature-responsive spirit is provided Quick, precision is high, the small environment temperature sensor of error.
A kind of environment temperature sensor described in the utility model, including copper shell, thermistor, pedestal, the pedestal If Packed inner cavity, the thermistor is equipped in the inner cavity, the thermistor lower end and the intracavity bottom are close, Plug connector is equipped in the copper shell, plug connector is fixed on by plastic interface in the copper shell, the plastic interface and institute It states and gasket is equipped between copper shell, the plug connector lower end penetrates the inner cavity and is fixedly connected on the thermistor, described Insulating layer is equipped between copper shell and the thermistor upper end, is noted between the pedestal madial wall and the thermistor lower end There is heat-conducting glue.
Further, the thermistor uses NTC type thermistor chips.
Further, the gasket is stamping forming sealed aluminum pad.
Further, the insulating layer is insulating cylinder made of insulating materials.
The advantages of the utility model and generation good effect are:Using high-precision NTC types thermistor chip, by leading Hot glue and copper shell experience ambient temperature, are exported in the form of resistance value, and temperature-responsive is sensitive, and precision is high, temperature error scope control It ± 1 DEG C, provides effective information to automobile urea tank control module and judges data, to indicate unlatching/closing of solenoid valve State;Standard waterproof connector is suitable for all corresponding standard harness;Simple in structure, production efficiency is high.
Description of the drawings
Fig. 1 is the utility model general structure schematic diagram;
Mark meaning is as follows in Fig. 1:It is copper shell 1, thermistor 2, pedestal 3, inner cavity 4, plug connector 5, plastic interface 6, close Packing 7.
Specific embodiment
It elaborates below in conjunction with the accompanying drawings to specific embodiment of the utility model.
A kind of environment temperature sensor, as shown in Figure 1, including copper shell 1, thermistor 2, pedestal 3, the pedestal 3 is set Packed inner cavity 4 is equipped with the thermistor 2 in the inner cavity 4, and 2 upper end of thermistor is located in plastic interface 6, 2 lower end of thermistor and 4 bottom of inner cavity are close, and the thermistor 2 uses NTC type thermistor chips, described The plug connector 5 of output signal is equipped in copper shell 1, the plug connector 5 is standard waterproof rank, and the plug connector 5 passes through plastics Interface 6 is fixed in the copper shell 1, and gasket 7, the gasket are equipped between the plastic interface 6 and the copper shell 1 7 be stamping forming sealed aluminum pad, and 5 lower end of plug connector penetrates the inner cavity 4 and is fixedly connected on the thermistor 2, institute It states and insulating layer is equipped between 2 upper end of copper shell 1 and the thermistor, the insulating layer is insulating cylinder made of insulating materials, Prevent 3 madial wall of pedestal from contacting generation short circuit, 3 madial wall of pedestal and the thermistor 2 with the thermistor 2 Heat-conducting glue is marked between lower end.
A kind of environment temperature sensor provided by the utility model, using NTC thermistor chip, resistance value when temperature is low Greatly, otherwise resistance value is small, exports as analog signal, using environment temperature outdoor during principle measurement running, leads to Direct current 12V voltages, small power consumption are crossed, the response of temperature output temperature is exceedingly fast, and precision is high, does not drift about.
Above-described embodiment is only the more excellent embodiment of the utility model, every according to the technical essence of the utility model pair It is made for any of the above embodiments it is any it is simple modification, modification and alternate variation, belong in the range of technical solutions of the utility model.
