A pluggable, close-fitting temperature sensor

Abstract

The invention relates to a pluggable and close-fitting temperature sensor. The temperature sensor includes a metal casing, a thermistor, two elastic retractable pins, packaging material and a fixing plate, the thermistor is arranged in the metal casing; the two ends of the retractable pin They are a free end and a fixed end respectively, the two retractable pins are parallel to each other, and their free ends are respectively electrically connected to the two electrode leads of the thermistor, and their fixed ends are arranged outside the metal shell; The encapsulating compound is filled in the metal shell, and the connection between the thermistor and the electrode leads of the thermistor and the retractable pins is packaged and fixed; the fixing plate and the two retractable pins The fixed end is fixedly connected. The temperature sensor of the present invention can effectively contact with the object to be measured, can realize rapid temperature measurement, has simple and reliable structure, strong practicability, and can be widely used in various occasions requiring temperature control and temperature compensation.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to an insertable and close-fitting temperature sensor. Background technique [0002] The NTC temperature sensor uses high-precision thermistor elements or chips with different appearance structures, and according to the different technical requirements of the actual application environment of the sensor, it adopts safe processing techniques such as soldering, metal cladding (pressing) bonding or micro-spot welding and reliable connection with wires. , and then carry out glue retention, insulation, moisture-proof and waterproof treatment, and apply epoxy resin encapsulation (potting) materials with excellent performance to seal and fix the thermistor element or chip in the metal or non-metal protective shell, forming a device that can meet the specific test requirements. Stable and reliable assembly of components required by temperature. [0003] NTC temperature sensor...

AI Technical Summary

Problems solved by technology

[0004] However, the existing NTC temperature sensor has the following defects: the hard contact method is used to contact the measured object, and when the shape or size of the measured object changes, it cannot be effectively contacted, resulting in temperature measurement deviation; The temperature is collected in the form of point contact, and the contact area is small, and there will be temperature measurement deviation; the response to collecting temperature is slow, and it is impossible to quickly and accurately measure and provide accurate temperature measurement signals
