  • Cap
    Publication number: 20190165514
    Abstract: A cap for attachment to a fastener comprises a securing base removably supported on a neck portion of the fastener, a hinge portion connected to the securing base, and a covering portion connected to the hinge portion. The securing base has a plurality of elastic beams defining a head portion passageway receiving a head portion of the fastener. The neck portion has a smaller diameter than a largest diameter of the head portion. The elastic beams are elastically deformed by the head portion during passage of the head portion through the head portion passageway. The covering portion is movable between an open position exposing the head portion and a covering position covering the head portion and overlapping with the securing base.

  • Patent number: 9837749
    Abstract: An electrical connector having a highly reliable electric shock prevention mechanism. The electrical connector has a housing, tab terminals, and a slidable member. The slidable member has engagement arms. The engagement arms have on forward sides fixed ends joined to a front side wall extending forward from an abutting wall, extend rearward in the form of cantilevers, and have hook portions. The hook portions engage with a mating electrical connector and this engagement causes the hook portions to be pulled by the mating electrical connector when the mating electrical connector in a mating state is extracted, so that the slidable member slides to a forward position. In addition, the housing is provided with anti-deflection walls. The anti-deflection walls allow the engagement arms to deflect so that the mating electrical connector can climb over the hook portions when the slidable member is located in the forward position.

  • Patent number: 9774125
    Abstract: A connector is disclosed. The connector has a housing, a terminal, and a moving plate. The housing has a mating connector receiving passageway and a raised portion formed inside the mating connector receiving passageway. The terminal is disposed in the housing and extends into the mating connector receiving passageway. The moving plate has a locking arm and an insertion hole into which the terminal is inserted. The moving plate is disposed in the mating connector receiving passageway and is movable between a front position in which a front end of the terminal is retracted inside the insertion hole and a rear position in which the terminal extends beyond the insertion hole. The raised portion abuts the locking arm and prevents deflection of the locking arm when the moving plate is located out of the front position.
