Abstract
Method of assembling a DC solenoid comprising: a coil; a thermistor connected in series to the coil and having a positive temperature coefficient; a pressure-resistant case for housing the thermistor; and a synthetic resin material for sealing the pressure-resistant case and the coil integrally.
Claims4
Method of assembling a DC solenoid with a thermistor, the steps comprising:
- connecting a thermistor having positive temperature coefficient in series with a coil;
- housing the thermistor in a case that is sufficiently resistant to pressure to substantially prevent damage to the thermistor on encapsulation of the case by injection molding material thereabout;
- and
- injection-molding a synthetic resin material to encapsulate and seal the case and the coil integrally while substantially preventing damage to the thermistor by the injection molding process.
