  • Patent number: 9704681
    Abstract: The conduction breaking device includes a conductive body, a fixed blade, an arc-extinguishing chamber, a gas generator, a cutting member, and a cutting delaying portion. The fixed blade and the arc-extinguishing chamber are located on one side of the cuttable portion with respect to a thickness direction of the cuttable portion in the conductive body. The gas generator is located on the opposite side of the cuttable portion with respect to the thickness direction. The cutting member is arranged between the cuttable portion and the gas generator and includes a movable blade. The cutting delaying portion is provided at the movable blade and configured to allow a part of an area of the cuttable portion that is, in the width direction, closer to the center than the edges are to the center to be cut after the other parts are cut.

  • Publication number: 20170076890
    Abstract: A conduction-breaking device breaks conduction between a pair of devices in an electric circuit. The conduction-breaking device includes a conductive body having a cuttable portion, an arc-extinguishing chamber having a pair of fixed blades, a gas generator, a cutting member having a pair of movable blades, and a deforming mechanism. When the cuttable portion is cut at two positions by the fixed blades and the movable blades, the cuttable portion forms a separated piece, which is separated from the electric circuit, and first and second remaining portions, which remain connected with the electric circuit. The separated piece has cut ends at opposite ends. The deforming mechanism deforms the separated piece such that the cut ends of the separated piece are located on a leading side in a moving direction of the cutting member with respect to a part of the separated piece between the cut ends.

  • Publication number: 20140083825
    Abstract: An electric circuit breaking device includes a housing, which has an accommodating portion, and a bus bar, which extends through the accommodating portion. The housing has a receiving chamber, which has an opening that opens toward the bus bar. The housing also accommodates a cutting blade such that the cutting blade faces the receiving chamber with the bus bar in between. The cutting blade is moved toward the receiving chamber to apply a shearing force to the bus bar, thereby cutting the bus bar. A restraint position is defined in the vicinity of the cutting blade and in an area about the opening of the receiving chamber. The accommodating portion accommodates a block. At the restraint position, the block cooperates with the housing to hold the bus bar, thereby restraining movement of the bus bar.

  • Publication number: 20140061161
    Abstract: A conduction breaking device includes a conductive body arranged between a pair of devices in an electric circuit, a gas generator, which is arranged away from the conductive body and generates gas, and a cutting member, which is arranged between the conductive body and the gas generator. The cutting member is moved due to gas from the gas generator to cut the conductive body, divides the conductive body into a first cut piece and a second cut piece, which have cut ends separated from each other, and breaks the conduction between the devices. The conduction breaking device includes an arc-extinguishing chamber. In the arc-extinguishing chamber, the conductive body is cut by the cutting member and an arc occurring between the cut end of the first cut piece and the cut end of the second cut piece is extinguished.
