  • Patent number: 9531127
    Abstract: A power feed connector includes: a tubular case that has a front end opening portion being open at a front end in a central axis direction; a connector main body that is accommodated inside the tubular case and is slidable in the central axis direction; an operation lever portion that has a first end being disposed inside the tubular case; a link mechanism that is directly connected to the connector main body and the operation lever portion and converts a turning motion of the operation lever portion into a linear motion of the connector main body in the central axis direction; and a grip portion that is integrally provided with the tubular case and extends in a direction intersecting the central axis direction.
    Type: Grant

  • Patent number: 8500476
    Abstract: A power-feed connector comprises a tubular case that has a front end opening portion; a connector body that is housed in the tubular case and can slide along a center axis direction of the tubular case; and an operating mechanism that operates the sliding of the connector body along the center axis direction, wherein the operating mechanism at least comprises an operating lever that is pivotally supported at the tubular case rotatably and a first end of which protrudes outside of the tubular case, and a conversion mechanism that converts a rotating force of the operating lever generated by moving the first end only into a force in the center axis direction of the tubular case; and a moving direction of the first end of the operating lever is coincident with a moving direction of the connector body which moves in association with the rotation of the operating lever.
