Abstract
Official abstract text for this publication.
The present invention relates to a direct current relay, and more particularly, to a direct current relay capable of reducing an electronic repulsive force generated between a fixed contact and a movable contact by a permanent magnet installed to extinguish an arc. The direct current relay includes: a frame; first and second fixed contacts spaced from each other with a predetermined distance there between; first and second magnetic substances formed to enclose a lower part of the first and second fixed contacts; a movable contact movable to contact or to be separated from the first and second fixed contacts, having a first movable contact contactable to the first fixed contact, and having a second movable contact contactable to the second fixed contact; and a pair of permanent magnets installed on long sides of the frame.
First claim
Opening claim text (preview).
What is claimed is: 1. A direct current relay, comprising: a frame; a first fixed contact and a second fixed contact spaced a predetermined distance apart; a first magnetic substance enclosing a lower part of the first fixed contact; a second magnetic substance enclosing a lower part of the second fixed contact; a first movable contact configured to contact or separate from the first fixed contact and a second movable contact configured to contact or separate from the second fixed contact; and a pair of permanent magnets installed on long sides of the frame, wherein each of the first magnetic substance and second magnetic substance is formed to have a ‘C’ shape. 2. The direct current relay of claim 1 , wherein: each of the first fixed contact and second fixed contact is formed to have a head part, a body part, and a leg part that form sequential steps; and each of the first magnetic substance and second magnetic substance is coupled to a circumferential surface of the body part or the leg part of the corresponding fixed contact. 3. The direct current relay of claim 2 , wherein each of the first magnetic substance and second magnetic substance is a ferromagnetic substance or a paramagnetic substance. 4. The direct current relay of claim 1 , wherein open parts of the each of the first magnetic substance and second magnetic substance are externally oriented. 5. The direct current relay of claim 4 , wherein each of the first magnetic substance and second magnetic substance is a ferromagnetic substance or a paramagnetic substance. 6. The direct current relay of claim 1 , wherein each of the first magnetic substance and second magnetic substance is a ferromagnetic substance or a paramagnetic substance.
