  • Publication number: 20190074683
    Abstract: An electrically-driven working apparatus in one aspect of an embodiment of the present disclosure comprises: a battery; an abnormality detection unit; a power supply path; a first disconnection unit; a second disconnection unit; and a control unit. The control unit activates the first disconnection unit to disconnect the power supply path if either of an overload or an over discharge of the battery is detected by the abnormality detection unit, and subsequently determines whether discharge from the battery has stopped after activating the first disconnection unit, and activates the second disconnection unit to disconnect the power supply path if discharge from the battery has not stopped.

  • Patent number: 10122103
    Abstract: A board connector includes: an L-shaped pin terminal including an insertion inserted into a through hole in a printed board and a conductor swaging part extending in a direction (+Y-axis direction) orthogonal to the insertion; and a housing disposed on one main surface (flat face on the +Z side) of the printed board, the housing containing at least an end of the conductor swaging part and having an opening into which a cable connected to the conductor swaging part is inserted. The board connector further includes a J-shaped boss formed integrally with the housing, the boss passing through a through hole in the printed board and protruding from another main surface (flat face on the ?Z side) of the printed board, extending in a direction (D2) (the +Y-axis direction) opposite to a direction toward the insertion, and further extending toward the printed board.

  • Patent number: 10069232
    Abstract: A female terminal includes a tube-shaped main body and an elastic contact plate supported inside the main body, possessing elasticity and extending from one opening toward another opening into which a male terminal is inserted. The elastic contact plate includes; a first section that faces the inner surface of the main body and is separated from the inner surface; a first contactor that is positioned on the other opening side of the first section and contacts the inner surface; a second section that extends in an arch shape toward the other opening from the first contactor; and a second contactor that is positioned on the other opening side of the second section and contacts the inner surface. The main body supports the elastic contact plate so the first contactor and the second contactor are able to slide on the inner surface. The first section is thinner than the second section.

  • Publication number: 20180233936
    Abstract: A power supply adapter according to one aspect of the present disclosure includes a power cord, a power-source attachment portion, a working-machine attachment portion, a temperature detector, and an overheat determiner. The temperature detector is configured to detect temperature of the power cord and to output a detection signal indicating the temperature detected. The overheat determiner is configured to determine that the power cord is in an overheated state based on the detection signal from the temperature detector and to output an overheat determination result indicating that the power cord is in the overheated state.

  • Patent number: 10014620
    Abstract: A connector includes an outer housing including an engagement catch, an inner housing and a sliding member. The inner housing includes an engagement latch, and a pair of locking arms each provided with the engagement latch. The inner housing includes a slide channel having the pair of locking arms disposed at both sides. The sliding member includes a pair of latching arms each provided with a latch. When the first housing and the second housing are engaged with each other, the first housing and the second housing allow the sliding member to pass through the slide channel, and when the sliding member slides the slide channel, the pair of latching arms are deflected so as to decrease a gap therebetween by depressions from the respective locking arms.
