Abstract
Provided is an electromagnetic switch device for starter in which an auxiliary relay is provided and which has a small size and can be easily manufactured. The electromagnetic switch device for starter includes: a main contact chamber forming a space in which a pair of main fixed contacts are located and a main movable contact can move; and a sub contact chamber forming a space in which a pair of sub fixed iron cores (A), (B) are located and a sub movable contact can move; and a cylindrical terminal block in which the main contact chamber and the sub coil are arranged so as to be adjacent to each other in the radial direction with a partition wall provided therebetween and separating the sub coil and the main contact chamber from each other.
Claims19
An electromagnetic switch device for starter, comprising:
- an electromagnetic switch which includes a pair of main fixed contacts, a main movable contact, an attraction coil, and a holding coil and which opens and closes an electric circuit for a motor via the pair of main fixed contacts, and when the attraction coil and the holding coil are energized, moves an overrunning clutch via a shift lever;
- an auxiliary relay which includes a pair of sub fixed contacts, a sub movable contact, and a sub coil, the pair of sub fixed contacts being connected to the attraction coil and the holding coil of the electromagnetic switch, the auxiliary relay energizing the attraction coil and the holding coil of the electromagnetic switch via the pair of sub fixed contacts in response to a starting signal;
- and
- a cylindrical terminal block to which a battery terminal connected to a plus terminal of a battery and a motor terminal connected to the motor are provided, and in which a main contact chamber and the sub coil of the auxiliary relay are arranged so as to be adjacent to each other in a radial direction with a partition wall provided therebetween, the main contact chamber storing the pair of main fixed contacts and the main movable contact of the electromagnetic switch, the terminal block integrally holding the electromagnetic switch and the auxiliary relay in parallel to an output shaft of the motor.
