摘要： PROBLEM TO BE SOLVED: To prevent steadily the operating handle from moving to OFF position in the adhesion state of the contactor.
SOLUTION: This is a switch mechanism 8 composed of an assembly of a handle lever 11 which is jointed to a handle 9 and of which top end is supported to a bearing part 17a of a side plate 17, a toggle link mechanism 12 which is bridged between a holder 7 and a latch 13 of a movable contactor 5, and an opening and closing spring 16 bridged between the connecting pin 12c of the link mechanism and the upper end base of the handle lever. As a means of preventing the operating handle from moving to OFF position in the state that the contact points of the fixed and movable contactors are adhered, mutually abutting stoppers 7b and 11b on which the operating handle is abutted with the cross bar of the contactor holder 7 and the handle lever 11 facing this at the position of OFF side beyond the dead point are provided. Furthermore, a second projection-shape stopper 17b is provided on the rear edge side of the handle lever so that the handle lever may be prevented from moving toward OFF direction using the abutting point of the stopper as a fulcrum.

摘要： PROBLEM TO BE SOLVED: To stabilize trip operation characteristics by simplifying the shape of a crossbar so as to improve its moldability, and by preventing unwanted sliding friction exerted between a pawl and a latch receiver in adjusting tripping current by axially moving the crossbar. SOLUTION: A trip crossbar 13 of a circuit breaker is provided between the operation end of a time limit tripping device and a latch receiver 12 connected to a latch 11 of a switch mechanism, and releases the latch 11 in response to the operation of an overcurrent tripping device. The trip crossbar 13 is composed of an insulating crossbar 15 and a pawl 21. The insulating crossbar 15 is journalled to a case 1 across poles, and on its shaft, an operation piece 16 opposite to an operation end of the overcurrent tripping device is formed. The pawl 21 latches and releases the latch receiver 12, according to rotational movement of the crossbar 15. The pawl 21 is rotatably supported separately from and parallel to the crossbar 15. An arm 21b projecting from the pawl 21 is abutted against the operation piece 16 of the crossbar 15 so that they are connected together.

摘要： PROBLEM TO BE SOLVED: To provide the fitting structure of a moving contact made of an elastic plate and a bimetal in which the fitting work of the moving contact and the bimetal is easy, and stress generating in opening/closing of the moving contact is not applied to the welded portion between the moving contact and the bimetal. SOLUTION: A fixing part 4 having a U-shaped cross section formed in the lower part of the base end of a moving contact 1 made of an elastic plate is fit to the lower end of a bimetal 5, the rear plate part 4c of the fixing part 4 is fixed to the rear surface of the bimetal 5 by welding. The force generating in opening/closing of the moving contact 1 is not applied to the rear plate part 4c where is the welded portion, and the risk of peeling off of the welded portion is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a circuit breaker excellent in breaking performance also in productivity such as assembly workability. SOLUTION: This breaker is equipped with a movable contact shoe 8 constituted so as to make opening/closing action by an opening/closing mechanism, a fixed contact shoe 3 folded into a nearly J-shape, and arranged so that the tip part can face the movable contact hose 8, and a casing for housing the opening/closing mechanism and the movable and fixed contact shoe 8 and 3. The fixed contact shoe 3 has a wide width part, which is formed, having width wider than that of the tip part, on a position opposite to the tip part in a section from the folded part of a J form to the base end part of the J form, and an extracting hole, which is formed on the wide width part, and the casing has a projection in a position on which the fixed contact shoe 3 in the bottom surface of the casing is mounted, to insert the projection into the extracting hole, and also the tip part is supported by the projection. Thus a circuit breaker excellent in breaking performance and also in productivity such as assembling workability is obtained.
