The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1-Fig. 6, the utility model preferred embodiment proposes a kind of air-conditioner back-off electric-controlled plate structure, this air-conditioner especially refers to the transducer air conditioning of outdoor back-off electric-controlled plate, the outdoor back-off electric-controlled plate structure of this air-conditioner comprises pcb board 100, is arranged in heater members and current sample noninductive resistance on pcb board 100, described heater members is fixed on to the support element 200 on pcb board 100, and the radiator 401 dispelling the heat for the heater members on pcb board 100, radiator 401 is placed in the top of described support element 200.
In existing air-conditioner back-off electric-controlled plate structure, after current sample noninductive resistance is plugged, when pcb board 100 is inverted installation of heat radiator 401 screw, current sample noninductive resistance can come off out, causes failure welding.
In the present embodiment, on described support element 200, in the position near described current sample noninductive resistance, be provided with screens, support element 200 is fixed on described current sample noninductive resistance on described pcb board 100 by described screens.
When assembling, respectively heater members and current sample noninductive resistance are plugged on pcb board 100, and pass through support element 200 respectively by heater members and current sample noninductive resistance stationary positioned, and afterwards pcb board 100 is inverted, by screw, radiator 401 is fixed on pcb board 100.Because the screens of current sample noninductive resistance by support element 200 is fixed on pcb board 100, like this, when assembling radiator 401 is inverted pcb board 100, can not cause current sample noninductive resistance to come off, and then can not affect the welding effect of current sample noninductive resistance yet.
