Abstract
A temperature sensor for preventing oil leakage comprises a cable which is composed of a wire core and an insulating layer. One end of the cable is fixedly connected with a probe. The probe comprises a metal pipe which is sleeved on an insulating layer at one end of the cable. The metal pipe is internally provided with a thermosensitive resistor which is electrically connected with the wire core. A first annular groove is rolled on the outer circumference of the metal pipe. The other end of the cable is fixedly connected with a metal protecting sleeve which sleeves the insulating layer. One end of the wire core is electrically connected with electrical elements in a terminal box. The metal protecting sleeve is internally provided with a rubber layer. A second annular groove is rolled on the outer circumference of the metal protecting sleeve. The annular grooves provided by the utility model respectively cause closer contact between insulating layer in the metal pipe and the metal protecting sleeve and the wire core, thereby preventing clearance between the insulating layer and the wire core, preventing oil leakage into the cable from a part between the insulating layer and the metal pipe and a part between the insulating layer and the metal protecting sleeve, preventing fire disaster caused by oil leakage into the electrical elements because of capillarity, and eliminating potential hazard.
Description
Technical field
The utility model relates to and belongs to sensor technical field, relates in particular to a kind of temperature sensor that prevents oil seepage.
Background technology
At present, existing when measuring electric machine rotation the temperature sensor of bearing temperature, all that temperature sensor is placed in the oil of high temperature for a long time, oil can leak in the cable of temperature sensor, due to capillarity, oil can leak in the terminal box being electrically connected to temperature sensor along cable, and easily breaking out of fire, exists potential safety hazard.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of temperature sensor that prevents oil seepage of good sealing effect is provided.
The utility model is to realize like this, a kind of temperature sensor that prevents oil seepage, comprise a cable, described cable is by core and be coated on described core insulation course around and form, described cable one end is fixedly connected with a probe, described probe comprises that one is set in the metal tube on the insulation course of described cable one end, in described metal tube, be provided with a thermistor, described thermistor is electrically connected to described core, on described metal tube excircle, roll extrusion has at least one for compressing the first ring connected in star of described cable, the metal coating sleeve pipe that the described cable other end and is set on described insulation course is fixedly connected with, described core one end is electrically connected to the electricity piece in a terminal box, in described metal coating sleeve pipe, be provided with for sealing the glue-line of described core, on described metal coating sleeve pipe excircle, roll extrusion has at least one for compressing the second annular groove of described cable.
Further, described metal coating sleeve pipe outer cover is provided with a plastic casing.
The temperature sensor that prevents oil seepage that the utility model provides, on metal tube excircle, roll extrusion has the first ring connected in star of at least one compression cable, first ring connected in star makes the insulation course in metal tube contact tightr with core, avoid gapped existence between insulation course in metal tube and core, stoped the oily meeting to leak in cable from the gap between insulation course and metal tube; On metal coating sleeve pipe, roll extrusion has at least one for compressing the second annular groove of cable, the second annular groove makes the insulation course in metal coating sleeve pipe contact tightr with core, avoid gapped existence between insulation course in metal coating sleeve pipe and core, also avoided the insulation course on cable to break because capillarity oil leaks in the electricity piece the terminal box being electrically connected to temperature sensor in cable; In metal coating sleeve pipe, be provided with for sealing the glue-line of core; glue-line can further prevent that oil from leaking in the electricity piece the terminal box being electrically connected to temperature sensor in cable; initiation fire has been eliminated potential safety hazard because capillarity leaks into from the gap between insulation course and core in the electricity piece of the terminal box being electrically connected to temperature sensor further to have avoided oil.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of the temperature sensor that prevents oil seepage that provides of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of temperature sensor that prevents oil seepage that the utility model embodiment provides, comprise a cable 1, cable 1 is by core 12 and be coated on core 12 insulation course 11 around and form, cable 1 one end is fixedly connected with a probe 2, probe 2 comprises that one is set in the metal tube 21 on the insulation course 11 of cable 1 one end, in metal tube 21, be provided with a thermistor 22, thermistor 22 is electrically connected to core 12, on metal tube 21 excircles, roll extrusion has at least one for compressing the first ring connected in star 3 of cable 1, the metal coating sleeve pipe 4 that cable 1 other end and is set on insulation course 11 is fixedly connected with, core 12 one end are electrically connected to the electricity piece in a terminal box (not shown), in metal coating sleeve pipe 4, be provided with the glue-line 5 of sealing core 12, on metal coating sleeve pipe 4 excircles, roll extrusion has at least one for compressing the second annular groove 6 of cable 1.
The temperature sensor that prevents oil seepage that the utility model provides, on metal tube 21 excircles, roll extrusion has the first ring connected in star 3 of at least one compression cable 1, first ring connected in star 3 makes the insulation course 11 in metal tube 21 contact tightr with core 12, avoid gapped existence between insulation course 11 in metal tube 21 and core 12, stoped oily meeting from leaking in probe 2 and in cable 1 between metal tube 21 and insulation course 11; On metal coating sleeve pipe 4, roll extrusion has the second annular groove 6 of at least one compression cable 1, the second annular groove 6 makes the insulation course 11 in metal coating sleeve pipe 4 contact tightr with core 12, avoid gapped existence between insulation course 11 in metal coating sleeve pipe 4 and core 12, also avoided the insulation course 11 on cable 1 to break because capillarity oil leaks in the electricity piece the terminal box being electrically connected to temperature sensor in cable 1; In metal coating sleeve pipe 4, be provided with the glue-line 5 of sealing core 12; glue-line 5 further prevents that oil from leaking in the electricity piece the terminal box being electrically connected to temperature sensor in cable 1; initiation fire has been eliminated potential safety hazard because capillarity leaks into from the gap between insulation course 11 and core 12 in the electricity piece of the terminal box being electrically connected to temperature sensor further to have avoided oil.
Further, described metal coating sleeve pipe 4 outer cover are provided with a plastic casing 7, and plastic casing 7 can avoid cable 1 because bending angle is large and metal coating sleeve pipe 4 end sidewalls multiple impacts fracture, and plays the effect of protection cable 1.
