Method for assembling arc-extinguishing chamber of electromagnetic contactor
View Patent ↗A method for assembling an arc-extinguishing chamber of an electromagnetic contactor includes a step of fixing a pair of fixed contacts each including a support conductor and a C-shaped part, to a bottom plate part of the arc-extinguishing chamber having a tub-shape with one end being open, the C-shaped part defining inside of the arc-extinguishing chamber; a step of installing an insulation cover covering a part other than a contact point part of each C-shaped part of the pair of fixed contacts; and a step of disposing a movable contact to be capable of contacting to and separating from the contact point parts of the fixed contacts.
1. A method for assembling an arc-extinguishing chamber of an electromagnetic contactor, comprising:
a step of fixing a pair of fixed contacts each including a support conductor and a C-shaped part, to the arc-extinguishing chamber having a tub-shape with one end being open, the C-shaped part being disposed inside of the arc-extinguishing chamber;
a step of installing an insulation cover covering a part other than a contact point part of each C-shaped part of the pair of fixed contacts; and
a step of disposing a movable contact to be capable of contacting with and separating from the contact point parts of the fixed contacts,
wherein the arc-extinguishing chamber comprises:
a flat fixed contact point supporting insulating substrate supporting the pair of fixed contacts;
a metallic angular cylindrical body brazed to the fixed contact point supporting insulating substrate; and
an insulating cylindrical body disposed on an inner circumferential surface of the metallic angular cylindrical body.
