  • Patent number: 11404814
    Abstract: A connector is provided with a first housing 10A and a second housing 10B to be arranged to cover a first facing surface 11A of the first housing 10A. The first housing 10A includes bearing portions 21 provided on a front end side and lock receiving portions 22 provided behind the bearing portions 21. The second housing 10B includes shaft portions 42 provided on a front end side and to be rotatably supported in the bearing portions 21, and partial locking portions 43 provided behind the shaft portions 42. The partial locking portions 43 lock the lock receiving portions 22 to temporarily hold the second housing 10B in a state inclined rearward from the shaft portions 42 away from the first facing surface 11A.

  • Patent number: 10559908
    Abstract: A terminal fitting (80) includes a projection (92) on an outer surface of a body (81). A housing (10) includes a cavity (11) into which the terminal fitting (80) is to be inserted, a guiding groove (23) into which the projection (92) enters, and an inverted insertion guiding groove (28) into which the projection (92) enters when the body (81) is in an inverted insertion posture. The housing (10) includes an inverted insertion guiding slope (32) formed on a groove surface of the inverted insertion guiding groove (28), inclined in a direction intersecting an inserting direction of the body portion (81) to face the projection (92) and configured such that the projection (92) slides on the inverted insertion guiding slope (32).

  • Patent number: 10418745
    Abstract: A connector housing (20) includes a receptacle (22) to be arranged in an opening (91) of a panel (90) obliquely with respect to a plate surface of the panel (90) and a jaw (27) protruding out from the housing body and having one surface facing the plate surface of the panel (90). A sealing member (50) has an annular shape to surround an outer periphery of the connector housing (20) and includes a panel lip (57) to be held in close contact with the plate surface of the panel (90) and inner and outer housing lips (58) to be held in close contact with the one surface of the jaw (27). A thickness of the sealing member in an in-out direction is reduced from the side of the housing lips (58) to the side of the panel lip (57).

  • Patent number: 9356375
    Abstract: A male terminal fitting includes a tubular main body (10) and a plate-like tab (40) projecting forward from the main body (10). A first support (51) and a second support (52) are provided respectively on a surface side facing in a direction of action of the external force (P1, P2) and a surface side opposite to the former surface side at a front end part of the main body (10) connected to the tab (40). The first and second supports (51, 52) serve as starting points of bending when an excessive external force (P1, P2) acts on the tab (40) in a direction intersecting with a projecting direction of the tab (40) and are displaced from each other in a front-back direction.
