Starter solenoid

The invention relates to a starter lifting magnet for use in Motor vehicles, and it is based on the task of providing a starter lifting magnet in an appropriate form.

According to the invention is a starter lifting magnet for a motor vehicle provided, which is characterized by a contact arrangement by means of which the lifting magnet is electrically connected directly to a pole bolt a battery can be connected and is supported by it.

The starter solenoid can either be attached directly to a perforated pole bolt rectangular cross-section can be attached by a screw connection or alternatively directly with a pole bolt of round cross-section be connected.

The starter lifting magnet expediently has a housing in which sits a solenoid with which a movable core cooperates, with a movable contact for movement with the core is arranged and set up two fixed, spaced contacts for connection by the movable electrical contact when the solenoid is energized is, wherein one of the stationary contacts is electrically connected to the contact arrangement and the other stationary contact is connected to a terminal for connection to a starter motor of the vehicle is.

The invention is described below on the basis of exemplary embodiments and

application in an arrangement for connection by a screw connection with a battery with a perforated pole pin of rectangular cross-section and

Pig. Fig. 2 is a transverse section showing modifications which are required to set up the solenoid for arrangement on a pole bolt, which has a round cross-section.

According to FIG. 1, the starter lifting magnet has a housing 1 with a 3ekkel 2, with a lifting magnet coil 3 seated in the housing, in which a core 4, which carries a movable contact 5, is displaceable. The lifting magnet also has two plague contacts 6 and 7, which are located on both sides of the core 4 at a distance. The core 4 is pressed by a peder 9 into a position in which the movable contact 5 is at a distance from the plague contacts 6 and 7. The lifting magnet coil 3 has power leads 10 and 11 which are connected to terminals 12 and 13, respectively, in order to enable current to flow to the coil 3.

The Pestkontakt 6 is electrically connected to a terminal 14, the is provided by a power supply (not shown) for connection to a starter motor of a vehicle. The other plague contact 7 is connected to an electrically conductive holder 15, which at 16 is perforated in order to fasten the bracket by means of a screw connection with a perforated pole bolt (not shown) on a battery in the motor vehicle ^ u. The bracket 15 is through a deformed extension of the contact 7 is held on the housing 1.

A screw goes through the hole 16 in the bracket 15 and through the pole pin in the battery is led to an electrical contact to effect between the solenoid and a terminal of the battery. The bracket 15 also serves as the sole support for the lifting magnet, which is thereby supported solely by the pole bolt. Of the

Terminal 14 is connected to the vehicle's starter motor, and As is known, the starter motor is grounded, as is the other pole pin of the battery. Ports 12 and 13 are in laid the circuit with the starter switch of the motor vehicle. When the solenoid 3 is energized, the starter switch is operated, the core 4 moves against the action of the springs 8 and 9, so that the movable contact 5 electrically the
