Description

Technical Field

[0001] The invention relates to the technical field of thermistors, in particular to an NTC single-ended glass-sealed thermistor. Background Art

[0002] NTC thermistor is a thermal-sensitive ceramic component made of transition metal oxide as the main raw material and using electronic ceramic technology.

[0003] After searching, the Chinese patent application with publication number "CN108492948A" discloses a combined thermistor, including a base with a mounting hole, a thermistor, an adsorption sleeve, a rotating pressure cylinder, a clamping block, a convex strip, a first magnet, a pressure cover, a through hole, an adjusting pressure seat, a push plate and a second magnet. When the thermistor is fixed by the above device, the adjusting pressure seat is tightened, and the clamping block presses the thermistor under the action of the thrust of the magnet. When the thermistor needs to be taken out, the adjusting pressure seat is loosened to take it out. The thermistor is easy to fix and take out, and the body will not be damaged, which is convenient for assembly and maintenance.

[0004] However, thermistors are all connected to the inside of a glass package by fixing the resistor and the connecting wire. If the internal resistor is damaged due to long-term use, or the glass of the package is damaged, the resistor or the glass of the package cannot be replaced, and the thermistor can only be replaced as a whole. In addition, since the connection between the thermistor and the device is welded through connecting wires or pins, if the thermistor is replaced as a whole, the welding part needs to be melted before the connecting wires or pins can be removed, which makes the thermistor inconvenient to replace, thereby reducing the use efficiency of the thermistor.

Moreover, since the connection between the thermistor and the device is welded through a connecting wire or a pin, if the thermistor is replaced as a whole, the welding part needs to be melted before the connecting wire or the pin can be taken out, resulting in the inconvenience of replacing the thermistor and reducing the use efficiency of the thermistor.
