  • Patent number: 9774129
    Abstract: Detecting pieces (27) are provided on an outer periphery of a connector housing (10) and a resilient grommet (60) is mounted on this outer periphery. When the connector housing (10) is incompletely inserted in a mounting hole (51) of a panel (50), the detecting pieces (27) project outward by interfering with the panel (50) and the grommet (60) is pressed to bulge outward by projecting portions (31) of the detecting pieces (27). When the connector housing (10) is correctly inserted into the mounting hole (51) of the panel (50), the detecting pieces (27) are resiliently restored and release a pressed state of the grommet (60) so that a bulging state of the grommet (60) disappears.

  • Patent number: 8894129
    Abstract: A vehicle body structure is proved that basically includes a pair of side frame members and a pair of suspension support members. The side frame members extend in a longitudinal direction of the vehicle body structure and are configured to absorb energy imparted during a collision in the longitudinal direction of the vehicle body structure by undergoing an axial collapse. The suspension support members are arranged parallel to the side frame members. The suspension support members serve to support a suspension link member, and are configured to bend during the collision. Each of the suspension support members includes a rotation inducing structure that is configured to induce a bending rotation of the suspension support members during the collision upon an imparted load input from the collision being equal to or larger than a predetermined value.

  • Patent number: 8388364
    Abstract: A joint connector has a housing (1) with cavities (3) into which female terminal fittings (2) are insertable, and a busbar (5) to be mounted in the housing (1). The busbar (5) has tabs (6) to be connected to the respective female terminal fittings (2) and adapted to short the female terminal fittings (2) to each other. The busbar (5) includes a base (15) used to mount the busbar (5) into the housing (1) and the tabs (6) are cantilevered from the base (15). The base (15) includes resilient legs (17) for allowing displacements of the tabs (6) in a direction crossing a longitudinal direction of the tabs (6). The tabs (6) can be displaced by displacements of the resilient legs (17) to absorb a misalignment between the tab pieces (6) and the female terminal fittings (2).

  • Patent number: 8317541
    Abstract: An opening (K) is formed in one side surface of a housing (1) to expose cavities (5) inside. Retaining portions (8) are formed in the cavities (5) to prevent female terminal fittings (7) accommodated from above the opening (K) from coming out backward by engaging the female terminal fittings (7). A cover member (2) includes a cover (15), which is slid along a plane direction of the opening (K) from a rear side of the housing (1). When the opening (K) is closed by the cover (15), thinned portions (36) of the cover (15) slip under locking walls (19) to prevent the cover (15) from coming out upward. Further, a lock arm (28) of the housing (1) is engaged with a locking edge of the cover member (2), whereby the cover member (2) is mounted on the connector housing (1).
