  • Patent number: 5328388
    Abstract: A modular connector for establishing multiple electrical connections through an opening in a vehicle body panel. A frame member, having opposite sides and mountable to the panel opening, has a means for sealing the body panel opening. The frame member has a plurality of connector module apertures. A cover, which is securable to one side of the frame member, has a plurality of connector module receptacles which correspond to and align with the connector module apertures. One or more female connector modules, each providing multiple terminals, mount in a receptacle in the cover and align with a frame opening. One or more male connector modules, each providing multiple terminals, aligns with a frame opening and mating to a corresponding female connector module. A means is provided for securing the female connector module to the male connector module.

  • Patent number: 5248263
    Abstract: A watertight electric connector has a male connector housing, a female connector housing to be mated with the male connector housing, a ring-shaped packing in close contact with an outer wall of the male connector housing, and a slidable protection cover disposed so as to cover the periphery of the packing. The protection cover protects the packing when the connector housings are not mated with each other, and is moved backward by the pressure of the female connector housing when the connector housings are mated. The slidable protection cover has a mechanism capable of making the watertight connector compact, simplifying the handling of the connector, assuring protection of the packing, and enhancing reliability of waterproofing.

  • Patent number: 5203719
    Abstract: A lock assurance mechanism for a connector having a pair of housings. A lock assurance member is attached to one housing having a lock arm in such a manner that the lock assurance member is movable back and forth relative to the housing, the lock assurance member having a flexible retaining lever with a retaining pin at a free end thereof. A guide wall having a guide holder for supporting the retaining pin is formed upright on the housing. A back-and-forth movement limitation piece for limiting back and forth movement of the retaining pin is provided on the other housing.

  • Patent number: 5145410
    Abstract: A waterproofing connector including a housing provided with a plurality of chambers in which wiring harnesses are fixed and with a rigid grid consisted of plates for partitioning the chambers, and a seal for sealing an end of the housing, the seal being provided with a plurality of holes in which the wiring harnesses are passed through to the chambers and with grooves for partitioning the holes. The plates of the rigid grid are inserted securely in the grooves of the seal respectively when the end of the housing is covered by the seal. The holes of the seal do not deform nor shift from chambers of the housing when the seal is put in the housing for sealing and when wiring harnesses are passed through the holes to the chambers, and good waterproofness is obtained between the holes and the wiring harnesses.

  • Patent number: 5106329
    Abstract: A socket contact is constituted by a general tubular-shaped body and a pair of opposed resilient members formed by splitting the front portion of the general tubular body with a pair of slits. One of the opposed resilient members has an inner surface having a pair of contacting portions at the predetermined peripheral intervals. The other opposed resilient member has an inner surface having a contact portion in confronting relation with a peripheral center of the pair of contacting portions of the one of the opposed resilient members. As a result, it is possible to clamp a male contact to be inserted stably between the opposed resilient members and then to keep a posture of the male contact with high contact pressure against the male contact.

  • Patent number: 5085599
    Abstract: A connector is disclosed wherein a flexible retaining piece for engagement with a terminal is disposed in a terminal receiving chamber of a housing body, and a spacer for preventing the flexing of the flexible retaining piece is inserted into a gap which allows the flexing of said flexible retaining piece. The abutment wall is provided in the housing body in opposed relation to a side surface of the flexible retaining piece. The spacer is provided in the gap so as to slide in a direction perpendicular to the side surface of the flexible retaining piece. Engaging holes and flexure prevention portions for the flexible retaining pieces are provided on the spacer and are arranged in the direction of slide of the spacer.
