Claims

[Claims for Utility Model Registration] 1. (1) A DC electromagnetic contactor having a normally closed contact in which a magnetic blowing effect is performed by a permanent magnet, characterized by having an arc shield formed by a magnetic pole plate, a permanent magnet, and porcelain. DC magnetic contactor. (2) In the electromagnetic contactor of utility model registration claim (1), the arc shield includes a magnetic pole plate support fixed to the fixed contact of the normally closed contact, a magnetic pole plate, and a magnetic pole plate support fixed to the fixed contact of the normally closed contact. A DC electromagnetic contactor, characterized in that it is attached to the fixed contactor by elastic action. (3) Scope of claims for utility model registration (1) or (2)
1. A DC electromagnetic contactor according to claim 1, wherein a support for the magnetic pole plate is fixed to a fixed contact of the normally closed contact, and a six is provided on the support for preventing rotation when the magnetic pole plate is fixed. (4) Scope of claims for utility model registration (1), (2), (3)
A DC magnetic contactor according to any one of the above, wherein the fixed contact of the normally closed contact is provided with a hole for releasing hot gas. (5) Scope of claims for utility model registration (1), (2), (3)
, (4), the arc shield includes a barrier part that protects members around the contact from the arc, a barrier part that prevents the arc from commutating to the magnetic pole plate, and a barrier part that prevents the arc from commutating to the magnetic pole plate. 1. A DC electromagnetic contactor characterized by having a wall section for stretching and cooling, and a recess section for mounting a permanent magnet. (6) Scope of claims for utility model registration (1), (2), (3)
, (4) or (5), wherein an auxiliary permanent magnet is provided above the normally closed contact.
