  • Patent number: 11677184
    Abstract: A connector configured to be fitted with a mating connector includes a main housing, a sub-housing supported on the main housing to be slidable in a fitting direction with respect to the main housing in which the connector is fitted with the mating connector, and an operating member pivotably and slidably supported on the main housing. The main housing moves closer to the mating connector when the operating member is pivoted from a first posture to a second posture. The sub-housing moves in the fitting direction when the operating member slides from the second posture in a direction different from the fitting direction. The sub-housing has an erroneous fitting prevention part abutting against the mating connector in a state of incomplete fitting of the connector with the mating connector.

  • Patent number: 11361913
    Abstract: A power accumulation system includes a power accumulation device, a relay device provided in a pair of power lines disposed between the power accumulation device and a power conversion device that exchanges power with the power accumulation device, a capacitor provided between the pair of power lines between the relay device and the power conversion device and an electronic control device that controls the relay device. The electronic control device is configured to execute a predetermined foreign matter removal process when it is not possible to bring one of a first relay and a second relay from a power blocking state to a conductive state.
