  • Patent number: 10008806
    Abstract: A lever-type connector includes a housing and a lever movably attached to the housing. The lever includes a side plate provided along a side surface of the housing, and an operation portion connected to the side plate. A boss is provided on the side surface of the housing. The side plate of the lever has an elongate hole into which the boss is inserted to restrict a moving range of the lever. An engagement stepped portion is provided at one end of the elongate hole. The engagement stepped portion is recessed on its outer side. The boss has an engagement projection provided at its distal end portion. The engagement projection extends along the elongate hole. The engagement stepped portion and the engagement projection engage with each other in a state in which the lever has been moved in a direction that separates the housing from a counterpart housing.

  • Patent number: 9972937
    Abstract: A lever type connector includes a male housing having a hood part, a lever rotatably supported on the male housing, a moving plate for positioning a tab part of a male terminal within the hood part and a female housing to be fitted into and detached from the hood part. By operating the lever forward, it is possible to allow the female housing to move to an inner side of the hood part together with the moving plate, thereby allowing the female housing to be fitted into the male housing. When the male housing is not fitted to the female housing, a rib of the lever abuts against a boss of the moving plate. When the abutment between the rib and the boss is released by operating the lever forward, the female housing is permitted to push the moving plate into the hood part.

  • Publication number: 20180102603
    Abstract: A protective cap is used when a male inner housing to which male terminals and electric wires are attached is passed through a bellows-shaped tubular portion of a grommet. A male outer housing mounted on an annular seal portion of the grommet and the male inner housing accommodated in the male outer housing in a state where the male inner housing accommodates and holds the male terminals connected to the electric wires constitutes the connector. The protective cap includes a circular cap main body having an accommodating recess that accommodates tab portions of the male terminals protruding more than a front face of the male inner housing, at least a front side of the male inner housing being fitted into the accommodating recess. An outer diameter of the cap main body is smaller than an inner diameter of the bellows-shaped tubular portion.

  • Publication number: 20170250418
    Abstract: A fuel cell system includes: a fuel cell; a reformer to generate a hydrogen-containing gas; an electric power generation raw material supply unit; a reforming material supply unit configured to supply at least one of reforming water and reforming air, to the reformer; an oxidizing gas supply unit to supply an oxidizing gas to a cathode of the fuel cell; a combustor to ignite an exhaust gas discharged from the fuel cell; and a controller. In an operation stop process of the fuel cell system, the controller causes the oxidizing gas supply unit to supply the oxidizing gas, causes the electric power generation raw material supply unit and the reforming material supply unit to intermittently supply the electric power generation raw material and at least one of the water and the air to the reformer, and causes the ignitor to perform an ignition operation.

  • Patent number: 9502812
    Abstract: A connector includes a pair of connector housings, a fitting part provided in one connector housing of the pair of connector housings, and a fitted part provided in another connector housing and to which the fitting part is fitted. The fitted part has a frame and a movable housing. The movable housing is arranged within the frame, and is movable in a fitting direction. Timing to complete fitting between the movable housing and the fitting part is different from timing to complete fitting between the frame and the fitting part. The frame and the movable housing have a locking part which temporarily locks the movable housing within the frame. The locking part is restored by releasing the temporary locking in a state in which the fitting between the fitting part and the movable housing is completed. A periphery of the restored locking part is covered with a protection part.
