摘要:
A method for assembling an arc-extinguishing chamber of an electromagnetic contactor is provided which is capable of easily assembling an arc-extinguishing chamber when the shape of a fixed contact is complicated. According to the method, an arc-extinguishing chamber of an electromagnetic contactor can be assembled by carrying out: a step of fixing a pair of fixed contacts (111) and (112), which is configured by a support conductor (114) and a C-shaped part (115), to a bottom plate part of a tub-shaped arc-extinguishing chamber (102) having an open end, this C-shaped part (115) configuring the inside of the arc-extinguishing chamber (102); a step of installing an insulation cover (121), which covers a part other than contact point parts, to the C-shaped part (115) of the pair of fixed contacts (111) and (112); and step of disposing a movable contact (130) so as to be able to come into contact with and separate from the contact point parts (118a) of the fixed contacts (111) and (112).

The invention relates to a solenoid housing having an elongated center pole comprising a non-magnetic region thereon for allowing actuation of an armature in response to electric current and a method of the making said solenoid housing. The instant invention eliminates the need for a two-piece construction of the center pole, leading to a simplified fabrication process, increased performance of product solenoid housing, and increased operational lifetimes as well.
