Description

A leaded thermistor assembly Technical Field

[0001] This utility model relates to the field of thermistor technology, specifically a thermistor assembly with leads. Background Technology

[0002] A thermistor is a special type of resistor whose resistance changes significantly with temperature. This component is made based on the property of material resistivity changing with temperature and is widely used in temperature measurement and control, overheat protection, circuit compensation, and other fields.

[0003] Thermistors, due to their high sensitivity, fast response, relatively simple structure, and ease of use, have become an indispensable component of modern electronic devices. However, their temperature range is limited. High-voltage thermistors are a special type of thermistor designed specifically for use in high-voltage environments. These components can operate stably under high electrical stress while maintaining their temperature sensing characteristics. They are typically used in applications requiring temperature monitoring and control under high-voltage conditions.

[0004] A leaded thermistor assembly is a temperature sensor that directly connects a thermistor element to a wire, making it easy to install and integrate into various circuits. However, the sealing effect of the lead mounting location in existing leaded thermistors needs improvement. Therefore, this invention proposes a leaded thermistor assembly. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a thermistor component with leads.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a thermistor assembly with leads, comprising a thermistor chip, one side of which is electrically connected to leads, and an insulating protective layer is provided on the outside of the thermistor chip. The insulating protective layer includes a chip protective sleeve covering the outside of the thermistor chip, and a lead protective sleeve covering the outside of the leads. By providing an insulating protective layer at the connection between the thermistor chip and the ends of the leads, the insulating protective layer can protect the ends of the thermistor chip and the leads during use, preventing current leakage, providing electrical isolation, and protecting internal components from physical damage or environmental factors.

[0009] The thermistor chip is provided with a shielding layer on the outside. The shielding layer includes a shielding layer body. A lead hole for mounting a lead wire is provided on one side of the shielding layer body. The lead hole is N-shaped. The shielding layer in this application has an N-shaped lead hole. Compared with a straight lead hole, the N-shaped lead hole has better sealing performance and thus better protection for the internal thermistor chip.

[0010] Preferably, the shielding layer body is formed by two symmetrical shell components joined together, and the two shells respectively include a first shielding layer and a second shielding layer.

[0011] Preferably, the first shielding layer and the second shielding layer are connected by connecting screws.

[0012] Preferably, the first shielding layer has a threaded hole inside, and the second shielding layer has a through hole inside, with the screw passing through the through hole and threaded into the inside of the threaded hole.

[0013] Preferably, the lead wire protective sleeve is embedded inside the lead wire hole.

[0014] Preferably, the lead wire protective sleeve is made of PVC or silicone rubber.

[0015] Preferably, the shielding layer body is made of aluminum or copper.

[0016] Beneficial effects:

[0017] Compared with existing technologies, this leaded thermistor assembly has the following advantages:

[0018] This invention provides an insulating protective layer at the connection between the thermistor chip and the lead end. During use, the insulating protective layer can protect the thermistor chip and the lead end, prevent current leakage, provide electrical isolation, and protect internal components from physical damage or environmental factors. Furthermore, the shielding layer in this application has an N-shaped lead hole, which provides better sealing than a straight lead hole, thus providing better protection for the internal thermistor chip.
