  • Patent number: 9825397
    Abstract: A grommet-equipped connector includes a connector and a grommet. The connector includes a panel engagement portion configured to be engaged with an attachment hole of a panel and an annular flange configured to face an edge portion of the attachment hole. The grommet includes a panel contact portion configured to be fitted so as to cover the flange and intimately contact the edge portion. A flange fitting groove in which the flange is inserted over an entire perimeter is formed inside the panel contact portion. The flange has a flange protrusion portion protruding outward and guided by the flange fitting groove.

  • Patent number: 8790132
    Abstract: A fixing structure of a connector includes a housing and a rear holder fixing the housing to a casing by screws. The rear holder has a base plate opposing the casing. First through holes are formed on the base plate so as to correspond to second openings for leading out conductive parts of the female terminals respectively. Terminal holding members are respectively provided at the first through holes for contacting the female terminals respectively. The screws are inserted respectively through second through holes which are arranged so as to deviate to one side with respect to a center of gravity of a region in which the first through holes are formed. Elasticity of one of the terminal holding members which is disposed at a first position facing at least one of the second through holes in a peripheral part of the region are smaller than elasticity of another one of the terminal holding members which is disposed at a position except for the first position.

  • Patent number: 6869555
    Abstract: In a rear holder-attached connector (1), a relatively-thick protective rib (10) with a width (B) projects outwardly from opposite sides of a housing (2), and is disposed between upper and lower terminal receiving chambers (3). This width (B) is larger than a width of rear holders (20a, 20b), and this rib (10) protects the rear holders (20a, 20b) so that these rear holders, provisionally retained on the housing (2) within a metal-mold assembly, will not be discharged from the metal-mold assembly to drop, and will not be disengaged from the housing even upon contact with another housing. The provision of the protective rib (10) also serves to provide a good flow of a resin poured from the rear side of the housing (2) during the molding operation, and therefore thin partition walls, forming the terminal receiving chambers (3), can be positively molded, thereby enhancing the yield of the molded housings.
