摘要： A contact device includes a pair of fixed contactors fixed to one side of an insulation container with a predetermined space therebetween and having a columnar shape with a tip end contact surface protruding at lease inside the insulation container, and a movable contactor disposed to be capable of contacting with and separating from the pair of fixed contactors. Surfaces of the pair of fixed contactors facing the movable contactor are formed of annular peripheral walls having a concave part at a center thereof. An annular arc is formed between the annular peripheral wall and the movable contactor when the contact device is in an open state.

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： 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.

摘要： A plurality of terminal chambers (20a) to (20e) is formed in a housing (16) by using a plurality of partition walls (24a) to (24e) to partition. In the terminal chambers, fixed contactors (31) each having a fixed contact point (31d) and a terminal screw (31a) are mounted. Engaged portions (31b) are formed integrally with the fixed contactors. Further, a press-fit engaging portion (26) is provided in each of the terminal chambers. The terminal chamber is formed as a space different from a space accommodating a movable contact point support, and the press-fit engaging portion is engaged by the engaged portion by press-fitting.

摘要： An electromagnetic contact device has a contactor holder (40), which moves a mounted movable contactor (42a) according to a displacement of a movable core (32) forming an electromagnet (30) for operation. The contactor holder (40) is being housed together with the electromagnet (30) for operation in a case (1). The case (1) has a lower case portion (10) housing the electromagnet (30) for operation and an upper case portion (20) engaging with the lower case portion (10) while being stacked on the lower case portion and houses the contactor holder (40) advanced from above. The upper case portion (20) has a recess (21) with an upward opening and houses the contactor holder (40) placed on the bottom wall of the recess (21). The lower case portion (10) houses one selected either a DC-only electromagnet (30b) or an AC-only electromagnet (30a).
