  • Patent number: 9306319
    Abstract: A connector includes a housing (10) into which terminal fittings (110) are accommodated and a housing-side lock (26). A wire cover (70) is mounted on the housing (10) to cover wires (200) pulled out from the housing (10). The wire cover (70) includes a cover-side lock (73) at a position to be lockable to the housing-side lock (26) in a mounted state and is held on the housing (10) by being locked to the cover-side lock (73) after the housing-side lock (26) is resiliently deformed. A restricting member (90) is inserted into a deflection space for the housing-side lock (26) to restrict the deflection of the housing-side lock (26) when the cover-side lock (73) and the housing-side lock (26) are in a locked state.

  • Publication number: 20160079703
    Abstract: A connector has a slider (60) with a base (61) extending along a width direction and to be inserted below a lock arm (17). Two arms (62) project from opposite widthwise ends of the base (61). A coupling (63) couples projecting end parts of the arms (62) and faces an upper surface side of the lock arm (17). A deflectable initial position holding portion (76) is provided on the base (61) and is configured to regulate a movement of the slider (60) to a connection position by resiliently locking an initial position holding receiving portion (25) of a housing main body (11) at an initial position. A connection position holding portion (64) is provided on the coupling (63) and is configured to regulate a detachment of the slider (60) by contacting a connection position holding receiving portion (23) of the lock arm (17) at the connection position.

  • Publication number: 20160064875
    Abstract: A connector includes a first housing (10) with a terminal accommodating portion (11) surrounded by a peripheral wall (17), a second housing (60) connectable to the first housing (10), and a detector (40) to detect a connected state of the housings (10, 60) based on whether the detector (40) moves from an initial position to a detection position in a space between the terminal accommodating portion (11) and the peripheral wall (17). An opening (22) extends circumferentially in a part of the peripheral wall (17) and exposes the detector (40). Deformation regulating portions (23, 53) are formed on the peripheral wall (17) and the detector member (40) and permit movements of the detector (40) between the initial position and the detection position and regulate deformation of the peripheral wall (17) to enlarge an opening width of the opening (22) by being fit to each other.

  • Patent number: 8608508
    Abstract: A rubber plug (10) has a plug main body (11) with at least first and second seal holes (13A, 13B) penetrating therethrough. Front and rear first lips (15A) are formed on the inner peripheral surface of the first seal hole (13A) and a valley (16) is defined between the first lips (15A). Front and rear second lips (15B) are formed on the inner peripheral surface of the second seal hole (13B) and a valley (17) is defined between the second lips (15B). The lips (15A, 15B) are disposed so that tips of the first lips (15A) align with the valley (17) of the second seal hole (13B). As a result, the first lips (15A) do not add to compressive forces exerted by the second lips (15B) when a wire is inserted into the second seal hole (13B).

  • Patent number: 8485833
    Abstract: A substrate connection part (4) of each of a plurality of press-fit terminals (3) pulled out of a housing (1) is inserted into a positioning hole (12) of a terminal arrangement member (11) to adjust alignment of the press-fit terminals (3) with respect to through-holes (7) of a substrate (6). The terminal arrangement member (11) is made of a thin resin sheet material. Each positioning hole (12) is sized so that the press-fit terminal (3) is placed in position by inserting a guide portion (9) of the press-fit terminal (3) therein. Slits (13) extend radially out from an opening edge of the positioning hole (12). When a press-fit portion (8) passes through the positioning hole (12), both slits (13) and the positioning hole (12) expand so that the press-fit portion (8) passes smoothly through the positioning hole (12).

  • Patent number: 8376761
    Abstract: A rib (54) of a sub-connector (30) is inserted into a groove (22) of a housing (10) if the sub-connector (30) is accommodated inside a correct accommodation concavity (11). A projected strip (77) of a wire cover (70) then is inserted into the groove (22) with the projected strip (77) and the rib (54) being side by side. Thus the wire cover (70) is prevented from being opened. The rib (54) may be inserted into the groove (22) if the sub-connector (30) is accommodated inside an incorrect accommodation concavity (11). But when an operation of mounting the wire cover (70) on the housing (10) in the above-described state is performed, the projected strip (77) interferes with the rib (54) inserted into the groove (22) to stop the mounting the wire cover (70) on the housing (10).
