Abstract
The utility model relates to a kind of novel outdoor temperature sensor, comprise NTC resistance and two wires, two of NTC resistance is connected with the input end of a wire respectively by a copper strips, a fixed resistance is also connected between the input end of two wires, fixed resistance and NTC resistance form parallel-connection structure, the input end of two wires, fixed resistance, copper strips and NTC resistance outer wrapping resin, silicone jacket is equipped with a plastic casing, after adopting above technical scheme: the utility model adopts at NTC resistor in parallel fixed resistance, then when extraneous temperature variation is larger, the resistance of fixed resistance is constant, resistance curve of the present utility model is made to compare existing fluctuation comparatively mild, plastic casing adopts the structure of L-type simultaneously, NTC resistance is then arranged on the termination, bottom of plastic casing bending, NTC resistance is made to be more prone to extraneous temperature be detected.
Description
Technical field
The utility model belongs to temperature sensor, specifically belongs to a kind of novel outdoor temperature sensor.
Background technology
Outdoor temperature sensor in the prior art, due to the factor of weather, the outdoor temperature of some areas there will be the change of large curve, but temperature sensor of the prior art, mainly NTC temperature sensor, when temperature variation is large, there will be the situation that the fluctuation of resistance curve is larger, namely when temperature is lower, the resistance of NTC resistance can become large, produces fluctuation.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of novel outdoor temperature sensor.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of novel outdoor temperature sensor, comprise NTC resistance and two wires, two of NTC resistance is connected with the input end of a wire respectively by a copper strips, a fixed resistance is also connected between the input end of two wires, fixed resistance and NTC resistance form parallel-connection structure, the input end of two wires, fixed resistance, copper strips and NTC resistance outer wrapping resin, silicone jacket is equipped with a plastic casing.
Two of fixed resistance is connected respectively by the input end of secondary copper strips with two wires, and NTC resistance and copper strips are outer ring in resin, and fixed resistance and time copper strips are inner ring in resin, and NTC resistance is arranged on the leftward position in plastic casing.
The xsect of plastic casing is the L-type of traverse, and the left side of plastic casing is the base of L font.
After adopting above technical scheme: the utility model adopts NTC resistor in parallel one with determining resistance, then when extraneous temperature variation is larger, the resistance of fixed resistance is constant, resistance curve of the present utility model is made to compare existing fluctuation comparatively mild, plastic casing adopts the structure of L-type simultaneously, NTC resistance is then arranged on the termination, bottom of plastic casing bending, makes NTC resistance be more prone to extraneous temperature be detected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cross sectional representation of plastic casing of the present utility model.
Embodiment
See Fig. 1, Fig. 2, a kind of novel outdoor temperature sensor, comprise NTC resistance 1 and two wires 2, two of NTC resistance 1 is connected with the input end of a wire 2 respectively by a copper strips 3, a fixed resistance 4 is also connected between the input end of two wires 2, fixed resistance 4 and NTC resistance 1 form parallel-connection structure, and the input end of two wires 2, fixed resistance 4, copper strips 3 and NTC resistance 1 outer wrapping resin 5, be set with a plastic casing 6 outside resin 5.
All parts of the present utility model is explained:
1) two of fixed resistance 4 is connected with the input end of two wires 2 respectively by secondary copper strips 7, NTC resistance 1 and copper strips 3 are outer ring in resin 5, fixed resistance 4 and time copper strips 7 are inner ring in resin 5, and NTC resistance 1 is arranged on the leftward position in plastic casing 6.
2) xsect of plastic casing 6 is the L-type of traverse, and the left side of plastic casing 6 is the base of L font.
After adopting above technical scheme: the utility model adopts at NTC resistor in parallel fixed resistance, then when extraneous temperature variation is larger, the resistance of fixed resistance is constant, resistance curve of the present utility model is made to compare existing fluctuation comparatively mild, plastic casing adopts the structure of L-type simultaneously, NTC resistance is then arranged on the termination, bottom of plastic casing bending, makes NTC resistance be more prone to extraneous temperature be detected.
