Jeffrey S. Campbell has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5968628
    Abstract: A molded structure formed in a mold having a space, the molded structure itself constituting a molding body when combined with an upper mold. The molded structure has a substrate which may be a carrier frame for an electrical connector. An insert which may be an elastomer is disposed on the substrate and formed in the space in the mold. A deformable (preferably elastic) molding seal is disposed directly on the substrate and under the elastomer, the molding seal preventing elastomer flash during molding. The molding seal may be a ridge surrounding the space of the mold in which the elastomer is formed. The substrate may also have a datum surface on which the mold locates, with the molding seal disposed in a plane which differs from the plane of the datum surface of the substrate. A process of molding the insert on the substrate is also provided.

  • Patent number: 5399101
    Abstract: An electrical connector for being electrically coupled to at least one electrical conductor. The connector includes a housing and at least one contact positioned therein and including a tip portion which protrudes from the housing to engage the conductor. Significantly, the contact, initially of a non-stressed configuration, is preloaded within the housing to assume a curved configuration and to engage the respective conductor in such a manner that sound, positive engagement occurs in a substantially non-wiping manner. The housing may thus be stationarily positioned relative to the circuit member, the circuit member able to thus press against the tip portion of the contact to complete coupling. The remaining part of the invention may be electrically coupled to an external conductor, e.g., a cable.

  • Patent number: 5228863
    Abstract: A connection device is provided for electrically coupling a primary circuit surface to a companion circuit surface via a flexible circuit strip for interconnecting the circuit surfaces. The connection device includes a companion positioner which has a companion-coordinating side, and a primary positioner which is coupled to the companion-coordinating side and which includes a primary-coordinating side. The companion coordinating side is adapted to be positioned parallel to the companion circuit surface, and includes a set of companion-positioner registrants for precisely positioning the companion-positioner relative to the companion circuit surface and a section of the interfacing circuit surface. The primary-coordinating side is adapted to be positioned parallel to the primary circuit surface, and includes a set of primary-positioner registrants for precisely positioning said primary-positioner relative to the primary circuit surface and another section of the interfacing circuit surface.

  • Patent number: 5199892
    Abstract: A connector assembly for effectively coupling two pairs of connectors wherein one of the pairs is located on a first member, e.g., a chassis, and the second pair is located on a rigid second member, e.g., a slidable card/board structure, adapted for being positioned relative to the first member such that the one pair of connectors on the second member engage the pair on the first member. The receiving connectors are each adapted for movement in response to engagement by the engaging (partner) connectors to thus compensate for possible misalignment of the second connectors. The first of these receiving connectors is movable in two different manners of direction while the second is movable in at least three (and in one embodiment, four) different manners of direction. A component for an information handling system which uses such a connector assembly as part thereof is also provided.
