Be provided with the first signal terminal in male component, in female component, be provided with the secondary signal terminal corresponding with the first signal terminal; One end of cable is connected with the temperature-sensitive layer in induction end, and the other end is connected with the first signal terminal or secondary signal terminal.
Further, described temperature-sensitive layer is single thermal resistor layer or two thermal resistor layer.
Further, when the temperature-sensitive layer in described induction end is single thermal resistor layer, cable is supporting red white two cables; Or when the temperature-sensitive layer in described induction end is two thermal resistor layer, cable is supporting red Bai Huangsan bar cable.
Further, described sensor also comprises: be socketed in the buckle that link 2 shell connects with the buckle on equipment.
Further, the outside of described induction end, link and cable scribbles reflectance coating.
As can be seen from above-mentioned concrete technical scheme of the present utility model, the utility model has following beneficial effect:
The utility model structure is simple; temperature survey is accurate; and can reuse; it realizes flashing by electronic temperature measurement and detects, and control errors is between ± 0.1 DEG C, and accuracy is very high; temperature-sensitive layer simultaneously in induction end of the present utility model has good insulativity, anti-pressure and abrasion-proof, impact resistance, heat-resisting quantity and reactance voltage effect; there is good physical strength simultaneously, enhance stability, protect copper cash better not by external influence.
Accompanying drawing explanation
