Abstract
The utility model discloses a water temperature sensor for an excavator. According to the technical scheme, the water temperature sensor is characterized by comprising an outer shell provided with an accommodating cavity with an opening; a fixing plate is fixed at the opening; the accommodating cavity is provided with a thermistor and is filled with insulating silica gel; wiring terminals electronically connected with the thermistor are arranged outside the outer shell; the fixing plate is fixed at the corresponding opening of the accommodating cavity and fits the inner wall of the outer shell in shape and size; and the other side of the fixing plate corresponding to the thermistor is provided with cured resin which connects the outer shell and the fixing plate and which forms an effective seal. By the technical scheme, according to the arrangement of the cured resin, the outer shell and the fixing plate are fixedly connected, and the opening of the outer shell is effectively sealed, seal performance of the water temperature sensor is improved, and measurement accuracy is guaranteed.
Description
Technical field
The utility model relates to a kind of cooling-water temperature sensor, and more particularly, it relates to the cooling-water temperature sensor that a kind of excavator is used.
Background technology
Engine coolant temperature sensor is called for short cooling-water temperature sensor or water temperature induction plug, and the temperature transition that is used for engine coolant is that electric signal is transported to ECU (Electrical Control Unit) (ECU), revises the basic fuel injection amount of engine.Modal is thermistor-type, and when water temperature was hanged down, the resistance of thermistor was big, and ECU detects high-tension signal, and ECU suitably increases distributive value, satisfies the requirement of engine low temperature rich mixture; When water temperature was high, the resistance of thermistor was little, and ECU detects the signal of low-voltage, and ECU suitably reduces distributive value, satisfied the requirement of engine high-temperature lean mixture.
Because need place water during cooling-water temperature sensor work could accurately measure fast as far as possible, so the waterproof measure of cooling-water temperature sensor just should be noted emphatically, general disposal route is to put in the metal catheter of sealing at one end, the inside is filling epoxy resin again, but because the erosion of surrounding medium, be easy to infilter water and go, causing between the thermistor supervisor of thermometric has hydrone, thereby the precision that causes measurement descends greatly.
The utility model content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of good seal performance, guarantees the cooling-water temperature sensor that the excavator of measuring accuracy is used.
For achieving the above object, the utility model provides following technical scheme: the cooling-water temperature sensor that a kind of excavator is used, comprise shell, shell is provided with the cavity volume of band opening, opening part is set with fixed head, be provided with in the cavity volume and be perfused with insulation silica gel in thermistor and the cavity volume, housing exterior is provided with the binding post that is electrically connected with thermistor, described fixed head is as for corresponding opening part in the cavity volume and all suitable with outer casing inner wall shape size, and the opposite side of the corresponding thermistor of fixed head is provided with the cured resin that shell and fixed head is linked together and form effective sealing.
By adopting technique scheme, the setting of cured resin not only can fixedly connected shell and fixed head, can also realize effectively sealing to the opening part of shell, improves the sealing property of cooling-water temperature sensor, guarantees measuring accuracy.
The utility model further is set to: described shell is provided with towards the inboard flange that extends of opening, and flange constitutes spacing the cooperation with fixed head, the coverage of cured resin and fixed head big or small suitable.
By adopting technique scheme, flange constitutes spacing the cooperation with fixed head, and the set-up mode of cured resin is substantially with flange and fixed head is fixed together and further improve the sealing property of cooling-water temperature sensor.
The utility model further is set to: described fixed head is connected with location-plate, fixed head, location-plate and binding post are fixedlyed connected by rivet, rivet is the hollow structure setting, and the hollow part of rivet is provided with scolding tin, and binding post and thermistor are electrically connected by scolding tin.
By adopting technique scheme, specialized the electric connection mode of sealing means, binding post and the thermistor of shell aperture end, and dexterously these two kinds of connected modes have been combined, simple and reliable for structure.
Description of drawings
The structural representation of the cooling-water temperature sensor embodiment that Fig. 1 uses for the utility model excavator.
Embodiment
The cooling-water temperature sensor embodiment that uses with reference to the utility model excavator of Fig. 1 is described further.
The cooling-water temperature sensor that a kind of excavator is used, comprise shell 1, shell 1 is provided with the cavity volume 12 of band opening, opening part is set with fixed head 4, be provided with in the cavity volume 12 and be perfused with insulation silica gel 3 in thermistor 2 and the cavity volume 12, shell 1 outer setting has the binding post 6 that is electrically connected with thermistor 2, described fixed head 4 is as for corresponding opening parts and all suitable with shell 1 inner wall shape size in the cavity volume 12, and the opposite side of fixed head 4 corresponding thermistors 2 is provided with the cured resin 5 that shell 1 and fixed head 4 is linked together and form effective sealing.
By adopting technique scheme, the setting of cured resin 5 not only can fixedly connected shell 1 and fixed head 4, can also realize effectively sealing to the opening part of shell 1, improves the sealing property of cooling-water temperature sensor, guarantees measuring accuracy.
Described shell 1 is provided with towards the inboard flange 13 that extends of opening, flange 13 and 4 spacing cooperations of formation of fixed head, the coverage of cured resin 5 and fixed head 4 big or small suitable.
By adopting technique scheme, flange 13 constitutes spacing cooperations with fixed head 4, and the set-up mode of cured resin 5 is fixed together flange 13 and fixed head 4 substantially and further improves the sealing property of cooling-water temperature sensor.
Described fixed head 4 is connected with location-plate 7, and fixed head 4, location-plate 7 and binding post 6 are fixedlyed connected by rivet 8, and rivet 8 is the hollow structure setting, and the hollow part of rivet 8 is provided with scolding tin 9, and binding post 6 and thermistor 2 are electrically connected by scolding tin 9.
By adopting technique scheme, specialized the electric connection mode of sealing means, binding post 6 and the thermistor 2 of shell 1 openend, and dexterously these two kinds of connected modes have been combined, simple and reliable for structure.
