Embodiment
The utility model is described in detail below in conjunction with embodiment.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
See Fig. 1 to Fig. 7, an embodiment of the sensor electrical appliance kit that the utility model provides, comprise base 100, top cover 200 and O-ring seal 300 (see Fig. 5), top cover 200 and base 100 closely fasten, is formed one for hold sensor circuit board 10 installation chamber and with chamber is installed and the cable tray 400 (see Fig. 1 and Fig. 7) extended to installation cavity outside.Base 100 is provided with base support 110, base support 110 is positioned at the inside (see Fig. 2) of installing chamber.Sensor circuit board 10 (see Fig. 4), is fixed on base 100 by base support 110, and keeps predeterminable range with base 100.Wherein, base 100 and top cover 200 can adopt that buckle is connected, linear sealing.The two installation chamber formed is the space of a relative closure.Top cover 200 is provided with air hole 210, extraneous air can only be entered by the air hole 210 that top cover 200 is arranged and install chamber (see Fig. 1 and Fig. 3).Usually, air hole 210 position is corresponding with sensor 11 position on the sensor circuit board 10 that installation cavity chamber interior is placed, and outside air enters sensor 11 by air hole 210.The shape of the shape and its inner sensor circuit board 10 held of installing chamber adapts.Base support 110 can be have certain thickness viscose glue, buckle or support column etc., and it acts on mainly fixation of sensor circuit board 10, and makes itself and base 100 noncontact.Base support 110 can be multiple according to its concrete structure, also can be 1.
See Fig. 5, O-ring seal 300 and the mating shapes of the sensor 11 that sensor circuit board 10 welds, closely can be socketed on the sensor 11, and wrap the welding position between sensor 11 and sensor circuit board 10; When top cover 100 fastens with base 200, O-ring seal 300 fits tightly with the surrounding of the air hole 210 on top cover 200.The material of O-ring seal 300 can be rubber or waterproof sponge, can directly be bonded on top cover 200.During installation, O-ring seal 300 is closely socketed on the sensor 11 of installation cavity chamber interior, to wrap the welding position between sensor 11 and sensor circuit board 10, realizes sealing the non-inductive face of whole sensor 11.When top cover 200 fastens with base 100, fit tightly with the surrounding of the air hole 210 on top cover 200 after O-ring seal 300 is squeezed, thus make the outside air entered from air hole 210 can only arrive the non-parcel face (namely sensitive surface) toward the outer side of sensor 11, and other regions of installation cavity chamber interior cannot be entered.
Traditional sensor electrical appliance kit, does not have O-ring seal.So, can certain interval be there is between the sensor that installation cavity chamber interior is placed and top cover, when outside air enters the sensor of installation cavity chamber interior placement from air hole, be easy to other regions entering installation cavity chamber interior.Like this, the moisture carried in air also just enters sensor circuit board, corrodes the welding position between sensor and sensor circuit board, to electrical safety threatens while impacting to the testing accuracy of sensor.And, traditional sensor electrical appliance kit is inner, sensor circuit board directly contacts with base, once there be moisture to enter electrical appliance kit inside, when freezing, electrical appliance kit is pressed close to vaporizer side and just very easily condensation is occurred, increase the weight of the corrosion that sensor mounting circuit boards is caused further, affect the safe operation of the inspection accuracy of sensor, serviceable life and complete machine.
The sensor electrical appliance kit that the utility model provides, by arranging O-ring seal 300 and of closely being fastened with base 100 by top cover 200 and being formed installs chamber, realizes the waterproofing protection to sensor circuit board 10.By arranging O-ring seal 300, well the weld of sensor 11 and sensor circuit board 10 being protected while guarantee measuring accuracy, avoiding extraneous water vapor and entering the reliability that installation cavity chamber interior destroys electrical equipment; Further, the base 100 of installation cavity chamber interior designs base support 110, sensor circuit board 10 and base 100 is made to keep predeterminable range, avoid sensor circuit board 10 to contact with base 100, when utilizing the thermal resistance of air to prevent from freezing, sensor circuit board 10 is pressed close to the vaporizer side of air conditioner and condensation occurs, and threatens the security appliance of sensor circuit board 10.The sensor electrical appliance kit that the utility model provides, water resistance is good, not easily condensation, can not have an impact, and greatly improve the operational safety performance of sensor serviceable life and complete machine to the inspection accuracy of sensor.
As a kind of embodiment, see Fig. 1 and Fig. 3, air hole 210 is streamlined structure, and air hole 210 is less than towards the aperture area of the one end outside top cover 200 towards the aperture area of the one end inside top cover 200.Shape and the evaporator shape of air hole 210 match, and better to touch from evaporator air out, in it, side opening is can the sensitive surface of uniform fold sensor 11 be good.
As a kind of embodiment, top cover 200 is provided with sealing strip, to promote the sealing effectiveness of whole installation chamber with the junction of base 100.Further, in cable tray 400 and the junction of installing chamber, adopt waterproof sponge parcel connecting line to seal, the sealing effectiveness of whole electrical appliance kit can be promoted.
As a kind of embodiment, see Fig. 1 to Fig. 3 and Fig. 6 to Fig. 7, top cover 200 is provided with also corresponding on base 100 mounting structure 500 being connected A/C evaporator side plate, and mounting structure 500 is positioned at the outside of installing chamber.Top cover 200 with base 100 arrange the mounting structure 500 being connected A/C evaporator side plate, does not need the mould changing original air conditioner type, can Fast Installation be realized.Mounting structure 500 is directly connected with A/C evaporator side plate, can be locating clip, snap close, installing plate etc. with mounting hole.
See Fig. 3, as a kind of embodiment, the inner side of top cover 200 is provided with stopper slot 220, and stopper slot 220 is positioned at the surrounding of air hole 210, with the mating shapes of O-ring seal 300.When top cover 200 fastens with base 100, O-ring seal 300 will be fixed in stopper slot 220, and structure is more firm.
See Fig. 2 and Fig. 3, as a kind of embodiment, base 100 comprises substrate 120 and is arranged on the waterproof shirt rim 130 of substrate peripheral, waterproof shirt rim 130 is provided with bayonet socket 131, top cover 200 is provided with the buckle 230 matched with bayonet socket 131, during installation, base 100 and top cover 200 are by buckle 230 and bayonet socket 131 clamping.
See Fig. 2, as a kind of embodiment, because common circuit board is square, so the base in the utility model is square, base 100 is provided with 3 drift angle places that 3 base supports, 110,3 base supports 110 lay respectively at base 100.See Fig. 4,3 angles of respective sensor circuit board 10 respectively arrange a fixed orifice, one of them in 3 base supports 110 is connected with sensor circuit board 10 by screw, all the other 2 base supports 110 are socketed or clamping with sensor circuit board 10, sensor circuit board 10 can be fixed, structure is simple, fixed.
