RELAY DEVICE HAVING IMPROVED STABILITY OF THE RELAY DEVICE AND CIRCUIT BY REDUCING ARC BETWEEN JUNCTIONS RECEIVING THE CURRENT FROM POWER SUPPLY

摘要

PURPOSE: A relay device for reducing arc using a magnetic force is provided to improve stability of the relay device and a circuit by reducing arc between junctions receiving the current from a power supply. CONSTITUTION: A relay device for reducing arc using a magnetic force includes an external switch, a coil(C), a resistor(R), and an internal relay. The coil and the resistor are parallel-connected with each other via a conductive line and are coupled with the external switch. The internal relay is opened/closed by an electromotive force of the coil. One of a node of the internal relay is coupled with a power supply via a relay terminal(20). A magnetic field guider includes the first hole for receiving the relay terminal and the second hole for receiving the conductive line. The conductive line and the relay terminal are magnetically coupled with each other by the magnetic field guider such that the relay terminal is subject to an electromagnetic force.
