Title:
ELECTROMAGNETIC CONTACTOR, DETACHABLE STRUCTURE FOR AUXILIARY UNIT, AND ASSEMBLY METHOD FOR MOVABLE HOOK SECTION PROVIDED ON AUXILIARY UNIT
Document Type and Number:
WIPO Patent Application WO/2011/092761
Kind Code:
A1
Abstract:
A movable hook section (13), which is provided on a unit-side connection surface (2a) of an auxiliary unit (2), is provided with: a hook section main body (14) formed from a claw (23a) and a pressed member (22); and a linear spring (15). The hook section main body (14) is slidably accommodated in a main body accommodation recess (16) formed in the unit-side connection surface (2a), and the linear spring (15) is accommodated in a spring accommodation recess (17a) formed in the unit-side connection surface (2a) in a direction perpendicular to the sliding direction of the hook section main body (14), and the longitudinal midsection of the linear spring (15) is engaged with the hook section main body (14). When the pressed member (22) is pushed, causing the hook section main body (14) to slide in a disengagement direction in which the claw (23a) and a hooking hole (8a) of an electromagnetic contactor (1) become disengaged, the elastic restoring force of the linear spring (15) which is elastically deformed in an arc shape is made to act on the hook section main body (14) in the opposite direction to the disengagement direction.
