The contact device has: a pair of columnar fixed contactors (6a, 6b) which are fixed to a surface of an insulation container (4) while keeping a predetermined space therebetween and each have at least a tip end contact surface protruding into the insulation container; and a movable contactor (11) that is disposed so as to be capable of coming into contact with and separating from the pair of fixed contactors (6a, 6b). Surfaces of the pair of fixed contactors (6a, 6b) that face the movable contactor (11) are configured by annular peripheral walls (9) having concave parts (9a) at central parts thereof. An annular arc is formed between the annular peripheral walls (9) and the movable contactor (11) when the contact device is in an open state.

摘要： A movable hook portion (13) provided in a unit side coupling surface (2a) of an accessory unit (2) includes a hook portion main body (14), which is formed with a movable claw (23a) and a pressed piece (22), and a straight spring (15), slidably accommodates the hook portion main body (14) in a main body accommodation concave portion (16) formed in the unit side coupling surface (2a), and accommodates the straight spring (15) in a spring accommodation concave portion (17a) formed in the unit side coupling surface (2a) so as to be orthogonal to a sliding direction of the hook portion main body (14), with a middle portion in a length direction of the spring being engaged with the hook portion main body (14). When the hook portion main body (14) is slid in a disengaging direction which brings the movable claw (23a) and a hooking hole (8a) of an electromagnetic contactor (1) into a disengaged state by pressing the pressed piece (24), an elastic restoring force of the straight spring (15) elastically deformed into a bow-like shape acts on the hook portion main body (14) in a direction opposite to the disengaging direction.

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 engaging with the case, and an engaging-force-decreased portion 5c2 which weakens the force of engaging with the case; and in response to an increase in internal pressure in the extinction chamber due to arcing gas generation, the engaging-force-decreased portion establishes disengagement of the case and provides a gap 27, formed with the case, for linking the extinction chamber to external air, and the engaging-force-increased portion maintains engagement with the case.
