Description
Technical field
The utility model relates to link and temperature transducer, the screw particularly with temperature sensing function.
Background technique
Current temperature transducer does not all have the effect of mounting article, so, the heating objects such as existing heat-generating electronic elements (as igbt chip), heating unit or the power circuit needing configuration radiator to help heat radiation/heat conduction, the other link (screw) of general needs is fixed, temperature transducer is then arranged on radiator surface, so that installation steps are various.In addition, because temperature transducer is arranged on radiator surface, easily receive external influence, so, it is generally low than the inner true temperature of radiator that radiator surface temperature surveyed by temperature transducer, radiator inside temperature then closer to the actual work temperature being arranged on object that radiator generates heat, causes thermometric inaccurate.
In addition, current temperature transducer is mainly divided into active temperature sensor and passive temperature sensor, and active temperature sensor is all equipped with signaling line, and during installation, signaling line brings certain obstruction to construction.And temperature transducer and signaling line are supporting, both are difficult to meet user's needs simultaneously.
Model utility content
An object of the present utility model is to provide a kind of simple and reasonable for structure, easy to use, easy processing, applied widely, both has temperature sensing function, and has again the screw of the band temperature sensing function of link function.
The purpose of this utility model is achieved in that
With a screw for temperature sensing function, comprise the screw body be made up of nut and stud, it is characterized in that: be provided with cavity in described stud, in cavity, be provided with temperature transducer.
The purpose of this utility model can also adopt following technical measures to solve:
As the first scheme more specifically, described temperature transducer is fixed in cavity by thermal insulation layer.
Described temperature transducer is active temperature sensor, and thermal insulation layer end face is provided with the link electrode be electrically connected with active temperature sensor.Or described temperature transducer is passive temperature sensor, thermal insulation layer end face is provided with the antenna be electrically connected with passive temperature sensor.
Described cavity top is opened wide and is extended to nut end face.
Described nut end face is provided with screw-driver insertion groove.
Described screw body is made up of metallic material.
As first scheme more specifically, described cavity is step hole.
As the third scheme more specifically, described nut periphery is provided with spanner screens.
The beneficial effects of the utility model are as follows:
(1) screw of this kind of band temperature sensing function is ensconced in screw body by temperature transducer, thus when not affecting screw function, make screw have the function of thermometric;
(2) temperature transducer is provided with link electrode, user can select separately the band header signal line meeting oneself requirement to coordinate with link electrode grafting, simultaneously, can after the heating objects such as heat-generating electronic elements (as igbt chip), heating unit or power circuit and radiator be connected and fixed, again signaling line plug is coordinated with link electrode grafting, facilitate the installation of circuit, also promote the quality of circuit;
(3), when the screw of this kind of band temperature sensing function is produced, first prepare the screw body being provided with cavity, then can be fixed in cavity by automation equipment by temperature transducer (not being with wire) on a production line, it produces easily;
(4) screw of this kind of band temperature sensing function has thermometric and fixed function, and user can judge by the temperature information obtained that heat-generating electronic elements (as igbt chip), heating unit or power circuit etc. generate heat object and radiator whether good contact.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
Embodiment one, and see shown in Fig. 1 to Fig. 3, a kind of screw with temperature sensing function, comprises the screw body 2 be made up of nut 22 and stud 21, is provided with cavity 24, is provided with temperature transducer 1 in cavity 24 in described stud 21.
Described temperature transducer 1 is fixed in cavity 24 by thermal insulation layer 13.
Described temperature transducer 1 is active temperature sensor, and thermal insulation layer 13 end face is provided with the link electrode 11 be electrically connected with active temperature sensor.
Described nut 22 end face is provided with screw-driver insertion groove 23.
Described cavity 24 top is opened wide and is extended to nut 22 end face.The link electrode 11 of described temperature transducer 1 is positioned at cavity 24, and when guaranteeing that driver bit coordinates with screw-driver insertion groove 23, driver bit can not touch link electrode 11.
Described screw body 2 is made up of metallic material.Because screw body 2 needs heat conduction, need again certain structural strength, so, preferred copper material in common metal material.
Its working principle is: to need to configure the heat-generating electronic elements (as igbt chip) that radiator helps heat radiation/heat conduction, the mounting structure such as heating unit or power circuit is example, screw with temperature sensing function in employing the utility model is directly by heat-generating electronic elements (as igbt chip), heating unit or power circuit are fixed on radiator, because screw body 2 is screwed in radiator, temperature transducer 1 is positioned at screw body 2, so temperature transducer 1 is not substantially by ectocine, and directly measure the temperature of radiator inside, with heat-generating electronic elements (as igbt chip), the temperature of heating unit or power circuit is the most close, thus obtain temperature information accurately.The link electrode 11 of signaling line and temperature transducer 1 connects after installing by screw body 2.In addition, by the feedback of temperature information, can judge again whether heat-generating electronic elements (as igbt chip), heating unit or power circuit fix or damage.
Temperature transducer 1 described above also can be passive temperature sensor, and thermal insulation layer 13 end face is provided with the antenna position of the antenna (can referring to figs. 1 to link electrode in Fig. 3 11) be electrically connected with passive temperature sensor.
Embodiment two, be with the difference of embodiment one: shown in Figure 4, described cavity 24 is step hole, step hole can have certain position-limiting action to driver bit, use than normally smaller driver bit once installation personnel, step hole will stop that smaller driver bit is inserted into the position of link electrode 11, in order to avoid injure link electrode 11.
Embodiment three, are: with the difference of embodiment one shown in Fig. 5 and Fig. 6, and nut 22 periphery is provided with spanner screens 25, and namely screw body 2 is turned by spanner.Because cavity 24 does not affect by screw-driver, so the link electrode 11 of temperature transducer 1 or antenna can be positioned at cavity 24, also can stretch out outside cavity 24, certainly, preferably link electrode 11 or antenna are positioned at cavity 24.
