Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1～Fig. 4, the utility model comprises housing 1, battery lead plate 2,4, PTC chip 3, draws fishplate bar 5, top sub 6, tip side daughter board 7, heater element 8, temperature-sensing element 9, spring terminal CD assembly 10, spring terminal D assembly 11, protector bottom 12, starter bottom 13, connector 14 etc.Housing 1 inside is divided into two chambeies, and wherein PTC chip 3 is loaded on the upper space of three core splicing ears in the 1-1 of chamber (be spring terminal C assembly 11, spring terminal CD assembly 10 and draw fishplate bar 5), and by 2,4 clampings of two cube electrodes; Its axial location is positioned at the middle part of three core splicing ears, and is parallel to the plane (see figure 2) at spring terminal CD assembly 10 and spring terminal C assembly 11 places.Spring terminal CD assembly 10, spring terminal C assembly 11 also are housed in the bottom of chamber 1-1 and draw fishplate bar 5 etc., by starter bottom 13 sealing, and with connector 14 fastenings.Temperature-sensing element 9, heater element 8, tip side daughter board 7, top sub 6 etc. are installed in another chamber 1-2 of housing 1, and by 12 sealings of protector bottom.C, M among other Fig. 3, the exit that the S terminal is expressed as three core splicing ears.
With reference to Fig. 5, B1, B2, B3 are overcurrent and overheating protection device binding post among the figure; P1, P2, P3 are PTC starter binding post; C, S, M represent the Samsung jack; Y represents compressor; T represents to move electric capacity.
When motor passes through super-high-current, heating wire in bimetal leaf in the temperature-sensing element 9 and the heater element 8 generates heat simultaneously because of the function of current, bimetal leaf in the temperature-sensing element 9 produces the action of deflection kick, make two moving contacts in the temperature-sensing element 9 leave tip side daughter board 7, cut off the electric current of electric motor loop, motor is quit work.When the operating ambient temperature of machine operation overlong time or motor is higher; the temperature of motor housing is raise; be installed in and produce the effect of deflection kick when the bimetal leaf in the temperature-sensing element 9 is heated in the overcurrent and overheating protection device on the motor housing; make the moving contact in the temperature-sensing element 9 leave tip side daughter board 7; cut off the electric current of electric motor loop, motor is quit work.Served as when flowing through the thermal protector temperature and being lower than the reset temperature of the bimetal leaf in the temperature-sensing element 9, the bimetal leaf in the temperature-sensing element 9 automatically resets, and the moving contact in the temperature-sensing element 9 is connected with tip side daughter board 7 again, makes motor restart work.
PTC chip 3 its cores are the PTC elements with positive temperature coefficient, are serially connected on the auxiliary winding of compressor Y by spring terminal CD assembly 10, spring terminal C assembly 11 and battery lead plate 2,4.Utilize the resistance-temperature characteristic of PTC element, under the heating effect of current effect, resistance increases rapidly, can reduce the auxiliary winding electric current rapidly after making compressor start, satisfies the compressor start requirement.
