Abstract
The utility model discloses a line ear type NTC temperature sensor mainly comprises metal substrate, insulating layer, thermistor, circuit spare and epoxy. Insulation cover is at the single face of metal substrate, thermistor hugs closely on the insulating layer, circuit spare is electrically conductive good metal, sets up on the insulating layer surface, thermistor's pin welding is on circuit spare, it has the wire still to weld on the circuit spare, epoxy fixes encapsulation such as thermistor, circuit spare on the metal substrate. The utility model discloses a line ear type NTC temperature sensor detects fast showing to the temperature and improves, and measured data is accurate, and is insulating effectual, and easy installation is difficult to warp.
Description
Technical field
The utility model relates to a kind of sensor, is specifically related to a kind of line ear type NTC temperature sensor.
Background technology
Current line ear type NTC temperature sensor be first the pin of thermistor with wire bonds together with, more whole thermistor comprised after pin insulating material encapsulates fix on online ear with epoxy resin.This structure, because thermistor is by wrapped with insulation, can reduce the speed of detection of thermistor, thermometric poor accuracy.
Utility model content
For solving the problem, the utility model provides a kind of line ear type NTC temperature sensor, and can improve the reaction velocity to temperature, measurement data is accurate.
The technical scheme that the utility model provides is: a kind of line ear type NTC temperature sensor, comprises metal substrate, thermistor, epoxy resin; Wherein metal substrate one end is equipped with hole; Thermistor is arranged on the correct position of metal substrate; It is characterized in that: also comprise insulation course, insulation course covers the one side of metal substrate, and thermistor is close on the insulating layer; Circuit part, circuit part is the metal of good conductivity, is arranged on surface of insulating layer, and the pin of thermistor is welded on circuit part.
The utility model has following beneficial effect: significantly improve temperature detection speed, and measurement data is accurate, and insulation effect is good, easily installs, and is not easy distortion.
