Embodiment Construction

[0026] refer to figure 2 The stabilization circuit of the starter magnetic switch according to the present invention will be described.

[0027] figure 2 is a circuit diagram showing the structure of the starter magnetic switch according to the present invention.

[0028] Connect the battery (BAT 11 ), that is, the same power is sent to the contact at one end (B 11 ), and the same power is sent to the holding coil (HL 11 ). This contact passes through the field coil (FL) of the motor unit 12 11 ) and the brush 12A are connected to the rotor 12B, and through the pull-in coil (PL 11 ) and diodes (D 11 ) to the contact at the other end.

[0029] In above-mentioned starter magnetic switch stabilizing circuit according to the present invention, after connecting key switch (KSW 11 ) to start the engine, the battery (BAT 11 ) power flows through the key switch (KSW 11 ) applied to the holding coil (HL 11 ), and through the pull-in coil (PL 11 ) and diodes (D 11 ) flow...

Abstract

The invention relates to stable circuit of magnetic switch for starter installed in engine of automobile. Diode disconnection key switch allows current passing through in normal direction, and prevents current from passing through in reversed direction so as to prevent current entering into attracting winding and holding winging. Thus, the insertion rod is returned back to original status. Motor unit stops working by disconnecting two connectors. When the diode connects the connector to the attracting winding, making the key switch turn to on, the attracting winding and holding winding are magnetized, and when the key switch is in off status, current does not enter into the attracting winding and holding winding, making the attracting winding and holding winding not be magnetized.

Description

technical field [0001] The present invention relates to a starter magnetic switch stabilizing circuit that can realize stable operation of an electronic switch for starting an engine installed in an automobile. Background technique [0002] The engine installed in the automobile is an internal combustion engine that cannot be started automatically. Therefore, in order to start the engine, it is necessary to rotate the crankshaft by external force. [0003] Furthermore, if the crankshaft of the engine does not exceed a certain number of revolutions, the engine cannot be started. [0004] Therefore, a starter is installed in the engine, where an electric motor for rotating the crankshaft of the engine at a certain number of revolutions is installed in the starter, and auxiliary equipment for controlling the driving process of the electric motor is installed. [0005] The electric motor of the starter rotates the crankshaft at a certain number of revolutions capable of startin...
