  • Publication number: 20220115793
    Abstract: The present invention provides an earth terminal which is provided with a water sealant layer on a connecting part connected to a wire, the earth terminal being provided with a structure that can suppress the occurrence of the floating of a seating surface of the earth terminal during an earth connection, the floating of the seating surface being caused by a water sealant hanging down in the earth terminal whereby the earth terminal exhibits superior effects in terms of space-saving and cost suppression. The present invention also provides a wire harness provided with the earth terminal. This earth terminal 1 is provided with a terminal fixture 10 having a crimping part 11 for crimping and fixing a wire 40, and a fastening part 15 connected to the earth surface by a fastening member, the terminal fixture 10 being provided with a step having a height D of 2.88 mm to 7.

  • Patent number: 9153909
    Abstract: A slide lever of a lever-type connector is a long plate-like member, inserted into a lever accommodation space of a main body side connector with a free longitudinal end thereof in the lead and arranged to be movable back and forth along an extending direction of the lever accommodation space. This slide lever includes a cam groove engageable with a cam pin projecting on a mating side connector. The cam groove includes an open end at an end surface of the slide lever extending in an inserting direction of the slide lever. A first path is connected to the open end portion and extends toward the free end with distance from the end surface. A second path extends away from the free end part with distance from the end surface and is connected to a deepest portion of the cam groove.

  • Patent number: 8496489
    Abstract: A force multiplying member (30) is mounted rotatably on supports of a first housing (10) and is guided slidably relative to the first housing (10). In a connecting process of the two housings (10, 20), the force multiplying member (30) successively performs a rotational movement that displays a force multiplying action by causing tracks (39) for rotational movement and cam followers (23) to slide and a sliding movement that displays a force multiplying action by causing tracks (40) for sliding movement and the cam followers (23) to slide.
