摘要： First fitting portions (9a and 9b) and second fitting portions (9c and 9d) are arranged in a hook shape on the bottom (3a) of a housing to face each other. The first fitting portions are fittingly engaged to one rail edge (2a) of a rail (2) in the width direction and the second fitting portions are fittingly engaged to the other rail edge (2b) of the rail. A linear spring (10) bent in a mountain shape is disposed on the bottom of the housing. The linear spring elastically deforms to reduce the inclination angle of the mountain by contacting the end surface of the one rail edge engaged to the first fitting portions. The urging force of the linear spring urges the rail such that the other rail edge is pressed by the second fitting portions.

摘要： The present invention provides a contact mechanism that is capable of, without enlarging the entire configuration thereof, preventing the generation of an electromagnetic repulsion that opens a movable contact upon application of a current, and also provides an electromagnetic contactor that uses this contact mechanism. A contact mechanism (CM) has a fixed contact (2) and a movable contact (3) that are inserted in a current-carrying path. In the contact mechanism (CM), at least either the fixed contact (2) or the movable contact (3) is formed into an L-shape or a U-shape so as to generate a Lorentz force that acts against an electromagnetic repulsion in an opening direction, which is generated between the fixed contact (2) and the movable contact (3) upon application of a current.

摘要： An extinction cover (5) is mounted on a case (4) thereby sealing an extinction chamber (S). This extinction cover has an engaging-force-increased portion (5c1) which strengthens the force of engagement with the case, and an engaging-force-decreased portion (5c2) which weakens the force of engagement with the case. In response to an increase in internal pressure in the extinction chamber due to arc gas generation, the engaging-force-decreased portion establishes disengagement of the case and provides a gap (27) with the case, for linking the extinction chamber to external air, and the engaging-force-increased portion maintains engagement with the case.
