Description

Double NTC temperature sensor

Technical Field

The utility model relates to a temperature sensor makes technical field, in particular to two NTC temperature sensor.

Background

The NTC temperature sensor is widely applied to the fields of automobile air conditioners, new energy battery packs, air intake and exhaust, water tank temperature sensors and the like. Most of the existing temperature control systems adopt a single temperature sensor to detect temperature in a certain temperature area, and after the single temperature sensor fails, the temperature control system is closed or stops the compressor, so that the ambient temperature changes and loses control, and the aim of accurately controlling the temperature cannot be fulfilled.

Disclosure of Invention

The utility model aims at overcoming the defect that prior art exists, provide one kind and ensured the temperature measurement accurate, avoid appearing temperature out of control's two NTC temperature sensor.

Realize the utility model discloses the technical scheme of purpose is: a double NTC temperature sensor comprises a shell and a wire harness pipe; two thermistors are fixed on the outer surface of the shell; the thermistors are isolated by the isolating piece, one ends of the two thermistors are connected, and the other ends of the two thermistors are respectively connected with the two leads.

In the technical scheme, the isolating piece is a sleeve; the two thermistors are respectively sleeved with a sleeve.

According to the technical scheme, the isolating piece is made of epoxy resin.

According to the technical scheme, the insulating solid pressure base is fixedly arranged in the sleeve.

In the technical scheme, a temperature fuse is also arranged in the shell; an insulating pad is arranged between the temperature fuse and the shell; the insulating pad is attached to the inner wall of the shell.

In the technical scheme, a double parallel self-extinguishing tube is arranged between the thermistor and the lead; the leads are respectively sleeved in the holes of the corresponding double self-extinguishing tubes.

The technical scheme is as follows: the shell comprises a cap-shaped upper shell and a cap-shaped lower shell which are mutually buckled; and a sealing ring is arranged between the cap-shaped upper shell and the lower shell.

After the technical scheme is adopted, the utility model discloses following positive effect has:

(1) the utility model discloses a two NTC thermistors are independent each other, link to each other with the wire, then pour it into in the shell with epoxy, form the insulator, ensured the temperature measurement accurate, avoid appearing the temperature out of control.

(2) The utility model discloses a be equipped with the insulating solid pressure base that has insulating properties, can effectively reduce the heat source and carry out the heat through the sleeve pipe and scatter and disappear, guarantee the true reaction ambient temperature change of NTC temperature sensor, improve measurement accuracy.
