Abstract

The utility model discloses a temperature sensor, belonging to the field of electric elements. The temperature sensor is simple in structure, convenient and fast in assembling and good in reliability, and can be used for engineering machinery. The temperature sensor comprises a heat conducting housing and a temperature sensing module arranged inside the heat conducting housing, wherein inside the heat conducting housing (3) there is fixedly provided a supporting member (4), the two pins of the temperature sensing module (1) are respectively welded and communicated with two metal sheets (5) inlayed inside the supporting member, and the other end of each metal sheet is connected with a lead (6). The temperature not only overcomes the defect that the temperature sensing module is easy to contact with inner wall of the heat conducting housing and to be invalid, enables the assembling difficulty to be reduced and the assembling efficiency to be greatly increased, and can be used for the engineering machinery.

Description

Temperature sensor

Technical field: the utility model relates to a kind of sensor, relates in particular to a kind of temperature sensor that is used for engineering machinery.

Background technology: well-known, temperature sensor is electronic devices and components commonly used on the engineering machinery, because the engineering machinery vibration is bigger, therefore the resistance to shock of temperature sensor is had relatively high expectations.At present, traditional temperature sensor generally all is by being located at temperature-sensitive module in the heat conduction shell, being fixedly connected with this temperature-sensitive module and being pressed on wiring board in the heat conduction shell, being filled in that the heat conduction colloid constitutes in the heat conduction shell by nut.Mainly there are following two big drawbacks in the temperature sensor of this traditional structure:

1) because the inner chamber of heat conduction shell is less, can only judge whether nut compresses wiring board through feel during assembling, so product quality can not get guaranteeing;

2) in the assembling process, be difficult to guarantee the placement of wiring board centering, the crator in the use on the wiring board might touch the inwall of heat conduction shell, thereby causes sensor failure.

Summary of the invention: in order to overcome the defective that exists in the prior art, the utility model aims to provide a kind of temperature sensor of quick, good reliability simple in structure, easy to assembly.

To achieve these goals, the utility model adopts following technical scheme: it comprises heat conduction shell, is located at the temperature-sensitive module in this heat conduction shell; The heat conduction shell internal fixation has support member, two pins of temperature-sensitive module respectively be embedded in this support member in the welding of two sheet metals be communicated with, the other end of each sheet metal is connected with lead.

Around the temperature-sensitive module, be filled with the heat conduction colloid.

Compare with prior art; The utility model is owing to adopted technique scheme; Utilization comes alternate route plate and nut with the support member of heat conduction shell inner chamber clearance fit; Therefore not only can guarantee accurately centering location of temperature-sensitive module, thereby thoroughly eliminate easy contact of temperature-sensitive module and the defective that lost efficacy with the heat conduction shell inwall; And reduced assembly difficulty, increased substantially efficiency of assembling.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the structural representation of conventional temperature sensor.

Among the figure: temperature-sensitive module 1 heat conduction colloid 2 heat conduction shells 3 support members 4 sheet metals 5 leads 6 wiring boards 7 nuts 8

Embodiment: the utility model is described further below in conjunction with accompanying drawing and concrete embodiment:

As shown in Figure 1: temperature-sensitive module 1 is placed on the bottom in the heat conduction shell 3, and the support member 4 that is " protruding " word structure is inserted in the heat conduction shell 3 and is wrapped up through the mode of rolling beading by the shell wall of this heat conduction shell and compresses; Two sheet metals 5 that are embedded in this support member are communicated with two pins welding of temperature-sensitive module 1 respectively, and it is protruding and be connected with lead 6 respectively that support member 4 is passed on the top of each sheet metal 5.Cause the temperature-sensitive module 1 and the inwall of heat conduction shell 3 to come in contact for fear of vibration, around temperature-sensitive module 1, be filled with heat conduction colloid 2.

Can know that from Fig. 2 the temperature sensor of traditional structure is to be pressed in the heat conduction shell 3 by the wiring board 7 that nut 8 will be welded with temperature-sensitive module 1; Therefore in the assembling process, not only the centering location is relatively more difficult for temperature-sensitive module 1, temperature-sensitive module 1 produces with the inwall of heat conduction shell 3 easily and contacts, and is difficult to nut 8 is tightened, and assembly manipulation is cumbersome.

Claims
