Patent number: 7901240Abstract: A connector comprises an adapter housing coupled to a connector housing. An adapter insert has a first cavity formed therein. The first cavity is shaped to at least partially restrain motion in a first lateral axis of a flat cable placed therein. An apparatus for connecting a flat cable to an electrical connector comprises an adapter housing. An adapter insert has a first cavity shaped to at least partially restrain motion in a first lateral axis of a flat cable placed therein. An elastomer spring element is disposed in a second cavity in the adapter insert.

Patent number: 7467979Abstract: An apparatus for engaging an electrical conductor comprises a gripping contact having a plurality of fingers, where the plurality of fingers has a substantially conical outer surface. A contact receptacle has a substantially conical inner surface. A tension member urges the gripping contact toward the contact receptacle such that interaction between the substantially conical outer surface and the substantially conical inner surface forces the plurality of fingers to engagingly compress the electrical conductor placed between the fingers. A method of engaging an electrical conductor comprises inserting an electrical conductor between a plurality of fingers of a gripping contact, where the plurality of fingers has a substantially conical outer surface. The substantially conical outer surface of the gripping contact is urged to interact with a substantially conical inner surface of a contact receptacle such that the interaction forces the plurality of fingers to engage the electrical conductor.Type: GrantFiled: July 20, 2006Date of Patent: December 23, 2008Assignee: Power Feed-Thru Systems & Connectors, LLCInventors: Michael G.

Patent number: 7455541Abstract: A connector comprises a substantially cylindrical housing having an internal circumferential groove therein. A seal element is disposed within the housing, the seal element having an axial passage therethrough. A plurality of circumferential sealing lips are spaced apart along the axial passage and sized such that each of the plurality of circumferential sealing lips provides a compression seal along a cable element inserted through the axial passage. A follower abuts the seal element. A spring is disposed in the groove acting against the follower and forcing the follower against the seal to maintain a fluid seal on the cable element.Type: GrantFiled: November 30, 2007Date of Patent: November 25, 2008Assignee: Power Feed-Thru Systems & Connectors, LLCInventors: Roy Jackson, Jeffrey W.
