  • Publication number: 20230327369
    Abstract: A waterproof connector is provided with a die-cast case including a box-like case body portion and a tubular portion projecting forward from the case body portion, the die-case case being formed of a cast product made of metal, and a housing made of synthetic resin and accommodated in the die-cast case. An inner peripheral surface of the tubular portion is formed with a sealing surface to be brought into contact with a sealing member of a mating connector. The sealing surface is an unprocessed surface not subjected to polishing after casting. A holding surface for holding the housing in a contact state is formed behind the sealing surface in the die-cast case. The holding surface is a processed surface subjected to polishing to make surface roughness thereof smaller than that of the sealing surface.

  • Publication number: 20230113196
    Abstract: -- A connector is provided with a movable conductive member (30) and a fixed conductive member (35) capable of electrically contacting a first conductor (42) and a second conductor (57) as connection objects, and a pressing member (25) made of a resilient insulating material and configured to apply a pressing force in a contact direction to the movable conductive member (30), the fixed conductive member (35), the first conductor (42) and the second conductor (57). The pressing member (25) includes a first pressing portion (26R) for applying a pressing force to the first conductor (42) and a second pressing portion (26F) for applying a pressing force to the second conductor (57). The first pressing portion (26R) and the second pressing portion (26F) are resiliently deformable independently of each other.

  • Publication number: 20230084529
    Abstract: A connector is provided with a female housing into which a first conductor and a second conductor are insertable, a movable conductive member accommodated in the female housing and electrically contactable with the first conductor and the second conductor, a fixed conductive member electrically contactable with the first conductor and the second conductor, and a pressing member made of a resilient insulating material and accommodated in the female housing. The pressing member applies a pressing force in a contact direction to the movable conductive member, the fixed conductive member, the first conductor and the second conductor. The female housing is formed with positioning portions for positioning the first conductor and the second conductor in a width direction orthogonal to both axial directions of the first conductor and the second conductor and a pressing direction of the pressing member.

  • Publication number: 20210273372
    Abstract: It is aimed to prevent water having intruded into a gap between a panel and a flange portion from remaining in the gap. A mounting structure for waterproof connector (13) is provided with a panel (10) formed with a through hole (11) and a waterproof connector (13). The waterproof connector 13 includes a connector housing (15) to be passed through the through hole (11) and a flange portion (16) formed on an outer periphery of the connector housing (15). A sealing ring (21) to be held in close contact with the panel (10) while surrounding the through hole (11) is mounted on the flange portion (16). A drain hole (12) is disposed between a hole edge part of the through hole (11) of the panel (10) and the sealing ring (21).
