Abstract
A self-fixing temperature sensor comprises a columnar temperature sensing cap, a thermistor and leads, the thermistor is mounted in the temperature sensing cap, the leads are connected with the thermistor, a height fixing platform and a transverse fixing part which can match with a mounting groove of a detected object are arranged on the side wall of the temperature sensing cap, and a fixing fastener is arranged on the height fixing platform. The self-fixing temperature sensor guarantees position consistency of temperature sensing portions. The fixing fastener is a sensor self-fixing part without additionally arranging a fixing part, mounting is simple, mounting cost is reduced, rotation of the sensor is limited, and consistency of temperature sensing positions is further guaranteed. Epoxy resin is filled in a temperature sensing cavity, sealing of the whole sensor is guaranteed while insulativity of pins of the leads is guaranteed, short circuit of the leads is prevented, a sheath on the leads further protects the leads against failure resulting from external influences, and safety and reliability of operation of the sensor are guaranteed.
Description
Technical field
The utility model relates to a kind of sensor, specifically, is a kind of from fixed temperature sensor.
Background technology
Temperature sensor is that a kind of being used for is converted into the components and parts that resistance is exported signal with temperature signal, is applied to nearly all field that needs the control temperature at present.
When installing, the sensor that adopts at present needs other mounting fixing parts or fixing buckle; Trouble is installed, and use cost is high, and fixing back is loosening easily and the position because can't accurately control when installing; Cause temperature-sensitive part position consistency property bad, make for the temperature survey of fixed position inaccurate.
The utility model content
The utility model is to existing temperature sensor, and fixed installation bothers, and cost is high, is prone to shortcomings such as loosening, has designed a kind of from fixed temperature sensor.
The utility model is from fixed temperature sensor; Comprise the temperature-sensitive cap; Be installed in the thermistor in the temperature-sensitive cap, the lead that links to each other with thermistor, described temperature-sensitive cap is a column; Temperature-sensitive cap sidewall is provided with the level altitude platform and the crosswise fixed part that can cooperate with the testee mounting groove, and the level altitude platform is provided with fixedly buckle.
Preferably, described fixedly buckle is a n shape, and fixedly buckle is provided with two resilient plugs, and the bottom of two plugs all is provided with block piece.
Preferably, described block piece is tapered, and the width at block piece top is greater than the width of plug.
Preferably, described level altitude platform is discoid, and described crosswise fixed part is block, and the bottom surface of crosswise fixed part and level altitude platform is positioned at same plane and partially overlaps.
Preferably, described temperature-sensitive cap is provided with the temperature-sensitive cavity, and temperature-sensitive cavity one end gos deep into the temperature-sensitive cap, and the temperature-sensitive cavity other end links to each other with the external world.
Preferably, thermistor is installed in the temperature-sensitive cavity, and thermistor is connected with wire bonds, is filled with epoxy resin in the temperature-sensitive cavity, and the end that epoxy resin temperature-sensitive cavity links to each other with the external world covers sealing.
Preferably, described lead is with sheath.
The utility model is provided with fixedly buckle from fixed temperature sensor, makes sensor all fixing in testee all around, short transverse position, has guaranteed the consistance of temperature-sensitive part position.Fixedly buckle is sensor self fixed part, need not the additional fastening parts, install simply, and reduced installation cost.Level altitude platform on the temperature-sensitive cap sidewall and crosswise fixed device cooperate with the mounting groove of testee, have limited the possibility of sensor rotation, have further guaranteed the consistance of temperature-sensitive position.The epoxy resin that charges in the temperature-sensitive cavity; Guarantee the whole sealing of sensor, guaranteed the insulativity that the lead pin is seen simultaneously, prevented the short circuit of lead; The lead upper jacket has further protected lead not receive ectocine and produce fault, has guaranteed the security and the reliability of working sensor.
Description of drawings
Accompanying drawing 1 is the cut-open view of the utility model from fixed temperature sensor;
Like Fig. 2 is the side view of the utility model from fixed temperature sensor temperature-sensitive cap;
Like Fig. 3 is the upward view of the utility model from fixed temperature sensor temperature-sensitive cap.
Embodiment
The utility model shown in Fig. 1 to 3, comprises temperature-sensitive cap 1 from fixed temperature sensor; Be installed in the thermistor 2 in the temperature-sensitive cap 1, the lead 3 that links to each other with thermistor 2, described temperature-sensitive cap 1 is a column; Temperature-sensitive cap 1 sidewall is provided with the level altitude platform 4 and crosswise fixed part 5 that can cooperate with the testee mounting groove, and level altitude platform 4 is provided with fixedly buckle 6, and described fixedly buckle 6 is a n shape; Fixedly buckle 6 is provided with two resilient plugs 9; The bottom of two plugs 9 all is provided with block piece 10, and described block piece 10 is tapered, and the width at block piece 10 tops is greater than the width of plug.
The fixedly buckle 6 of sensor is inserted in the corresponding hole of testee; Resilient plug 9 bends inwards, and block piece 10 passes the hole of testee, and plug 9 props up block piece 10 through the elasticity of itself; Fixedly buckle 6 blocks sensor; Level altitude platform 4 inserts in the mounting groove of testee with crosswise fixed part 5, and sensor is completely fixed, and sensor can be measured the temperature of same position more accurately.
