Abstract
The utility model relates to a PTC air conditioner starter, which comprises a hollow casing. The upper end of the casing is provided with a cover plate; a PTC chip supported by an insulating plate is arranged in the casing. One end of each of two terminals is an elastic part clamping the PTC chip and is positioned in the casing; the other end of each of the two terminals extends out of the cover plate and is connected with a secondary winding loop of a motor of the air conditioner. After the motor is started, the resistance raises a plurality of orders of magnitude, and the secondary winding is switched off by the utility model in fact according to PTC characteristics. The utility model can always ensure reliable contact because of no contact points, and the service life is prolonged. Better reliability is ensured because of variance in self resistance of the PTC with no mechanical force and mechanical motion.
Description
The utility model belongs to the monophase machine starter, especially a kind of PTC (semistor) motor starter, international Patent classificating number H02P1/42.
If monophase machine power is bigger, generally to disconnect auxiliary winding after the starting, existing starting switch generally has centrifugal and electromagnetic type etc.A kind of monophase machine starter was disclosed on July 22nd, 1998 as Chinese utility model patent communique, application number 97211806, authorization notification number CN2286540, this starter comprises base plate, terminal block, electromagnetic starting switch and outlet box cover, terminal block and electromagnetic starting switch importantly are installed on base plate side by side, electromagnetic starting switch has an electromagnetic core that is twining coil, and its coil tandem is in the motor main winding, and movable contact and break are serially connected in the startup winding of motor.Centrifugal operation is unreliable, the situation of burning motor is often arranged, and electromagnetic switch loses efficacy because of loose contact, sparking etc. also because of the contact is arranged.If allow auxiliary winding participate in operation, then can increase power loss.The easier fault that causes when Fraquent start especially.
The purpose of this utility model does not have the PTC starting of air conditioner device of mechanical movement when providing a kind of reliable, contactless startup, switch motion.
The purpose of this utility model is achieved in that a kind of PTC starting of air conditioner device, it comprises hollow shell 2, shell 2 upper ends are provided with cover plate 1, the PTC chip 6 that supports with insulation board 4 is set in the shell 2, one end of two-terminal 3 is the elasticity position, is positioned at housing, and PTC chip 6 is clamped at the elasticity position, the other end of two-terminal 3 passes cover plate 1, and is connected with air conditioner motor auxiliary winding loop.Shell 2, cover plate 1 are flame-retarded resin.
Because the utility model adopts two spring terminals to clamp the PTC chip, the flame-retarded resin shell of packing into, with the cover plate encapsulation of shell same material, two-terminal is fixed on the motor auxiliary winding during use.According to the characteristics of PTC, behind the electric motor starting, its resistance rising several magnitude is actually auxiliary winding is disconnected.Therefore it does not have the contact, can guarantee all the time contact reliably, increases the service life.Its on-off action is because the variation of PTC self resistance does not have mechanical force and mechanical movement, has guaranteed its reliability preferably.PTC starting of air conditioner device increases the effect of detent torque in addition.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the end view of Fig. 1.
Among the figure: 1, cover plate, 2, shell, 3, terminal, 4, insulation board, 5, screw, 6, the PTC chip.
PTC chip 6 is clamped at the elasticity position of two-terminal 3, supports with insulation board 4, and the shell 2 of packing into covers cover plate 1, and is fixing with screw 5.Shell and cover plate are flame-retarded resin.No matter insert with terminal 3 during use, tap in the air conditioner motor auxiliary winding loop, be frequent starting or long-play, can guarantee that all it is in normal condition.
Claims (2)
