The utility model provides a removable formula NTC module conveniently directly changes, more practices thrift the cost like this.

Description

Replaceable NTC module

Technical Field

The utility model relates to a temperature sensor, especially removable formula NTC module.

Background

In the prior art, wires are connected with the NTC chip, and a client generally adopts a welding mode and cannot replace or maintain the NTC chip. In addition, the product in the prior art is large in size and large in occupied space, and cannot meet the use requirement of integration.

The 'modularized heat conduction temperature measurement sensor' in the patent with the application number of '201920210765.6' is a patent applied by the company in 2019, is small in size and small in occupied space, can meet the integrated use requirement, but a customer still adopts a welding mode for connection and cannot be replaced when using the sensor.

Disclosure of Invention

The utility model aims to solve the technical problem that a removable formula NTC module is provided, conveniently directly changes, more practices thrift the cost like this.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:

the replaceable NTC module comprises a connector terminal, wherein the connector terminal is integrally injection-molded with the shell to form a connector; one end of the connector terminal is welded with the NTC, and a shell is fixed outside the NTC; the other end of the connector terminal is detachably connected with the circuit element.

The connector terminal comprises a terminal main body, wherein one end of the terminal main body is provided with a welding electrode, and the other end of the terminal main body is provided with a tuning fork type socket.

The shell is a metal shell, and epoxy resin is filled between the interior of the shell and the NTC.

The circuit element is an FFC or FPC, and a reinforcing plate is attached to the lower portion of a copper foil of the FFC or FPC.

The shell is provided with an anti-falling buckle, and the shell is sleeved on the shell and is clamped through the anti-falling buckle.

The utility model discloses removable formula NTC module has following technological effect: the connector terminal and the shell are integrally injected by an injection mold to form the connector, and the connector is welded with the NTC and then is connected with the FPC or the FFC in an inserting mode, so that the replaceable NTC module is formed and is convenient to disassemble and replace.

In the figure: connector terminal 1, casing 2, NTC3, shell 4, circuit component 5, anticreep buckle 6, terminal main part 1.1, welding electrode 1.2, tuning fork socket 1.3.

Detailed Description

As shown in fig. 1-2, the replaceable NTC module includes a connector terminal 1, a housing 2, an NTC3, and a housing 4.

As shown in fig. 2-3, the connector terminal 1 includes a terminal main body 1.1, two sets of welding electrodes 1.2 are disposed at one end of the terminal main body 1.1, the two sets of welding electrodes 1.2 are welded with two pins of NTC3 into a whole, and the NTC3 is a glass-bulb product, and is moisture-proof and high-temperature resistant. The other end of the terminal body 1.1 is provided with a tuning fork type socket 1.3, and the upper and lower elastic plates of the tuning fork type socket 1.3 can clamp and keep contact with the circuit element 5, and the direction can be not limited.

As shown in fig. 4-5, the connector terminal 1 is injection molded integrally with the housing 2 and forms a connector. The thin rear end of 2 front ends of casing is thick, and lateral wall is fixed with wedge-shaped anticreep buckle 6 about 2 front ends of casing, and shell 4 overlaps on casing 2 and through 6 joints of anticreep buckle. The shell 4 is a metal shell and epoxy resin is filled between the inside of the shell and the NTC 3. Thus, the temperature can be sensed conveniently, and the thermal reaction is rapid.

As shown in fig. 2, the circuit element 5 is an FFC or an FPC, and a reinforcing plate is attached to a copper foil of the FFC or the FPC. The reinforcing plate can increase the strength and facilitate conduction after the connector terminal 1 is inserted.
