Abstract: A breaker device excellent in safety and contained in a compact casing. In a casing 1, a pair of fixed electrodes 11a, 11b is projected, and a movable electrode 31, which is fitted with and detached from the fixed electrodes, is arranged. A handle 40 is inclinably supported by a supporting shaft 45. On the top surface of an upper casing 3, a pair of poles 70 is erected, and rectangular solid sliding projections 71 are projected, while guiding grooves 73 are formed in side faces of the handle 40. In each of the guiding grooves 73, an arc-shaped portion allowing the sliding projection 71 to rotate about the supporting shaft 45 is provided at an upper end of a linear portion which allows the sliding projection 71 only to slide therealong. When the movable electrode 31 is inserted with the handle being erected, the sliding projections are guided by the linear portions, while the handle 40, maintained in an erected state, is inserted.

Abstract: A first connector of a pair of connectors fitted has a shell accommodating a second connector of the connectors. By fitting both connectors, female terminals and male terminals are connected to each other. The second connector includes an outer case removably inserted in the shell, an inner case incorporated in the outer case and inserting female terminals therein, a cylindrical body accommodated rotatably in the outer case, and a locking member with an operating lever formed on the cylindrical body. An abutting-on portion in the cylindrical body on the side of the shell has a first magnetic substance. Another abutting-on portion in the shell on the side of the cylindrical body has a second magnetic substance having a polarity opposite to that of the first magnetic substance.

Abstract: A ground structure for a shield wire that can withstand a pulling force to a certain degree includes notches formed through a peripheral wall of a housing defining a tubular member. Spring pieces are mounted respectively in the notches and project from the inner and outer peripheral surfaces of the housing. The housing is received in a shield cap, which is connected to a metal casing. When a shield wire, having an exposed braided wire exposed, is passed through the bore of the housing, the spring pieces contact the shield wire at the inner periphery of the housing and the shield cap at the outer periphery of the housing. Therefore, the braided wire and the metal casing are electrically connected together. Also, the shield wire is movable in an axial direction, so that the shield wire will not be broken even if a pulling force acts on the shield wire.

Abstract: This invention provides a charging apparatus for an electric vehicle which prevents a charging coupling from becoming overheated and melting upon charging. In the charging apparatus, when a lever 33 provided on a supply connector 2 is grasped, the supply connector 2 is completely fitted to a vehicle inlet 1 by a pair of stays 36 connected to the lever 33. A slide switch 42, which serves to open and close a charging circuit in the supply connector 2, is inhibited from being operated by a stopper face on the lever 33 under a normal condition and allowed to be operated when the supply connector 2 is completely fitted to the vehicle inlet 1. When a microswitch 44 associated with the slide switch 42 is turned to ON, a relay 90 in a charger 74 is energized to close the charging circuit, thereby enabling conduction from a power source to a battery.
