  • Patent number: 7901240
    Abstract: 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. The elastomer spring element imparts a squeeze on the flat cable at least partially restraining motion of the flat cable in a second lateral axis substantially orthogonal to the first lateral axis.

  • Publication number: 20090203243
    Abstract: A connector comprises a housing having a seal element located within the housing. The seal element has 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 seal for an electrical connector comprises an elastomer 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.

  • Patent number: 7467979
    Abstract: 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.

  • Patent number: 7455541
    Abstract: 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.

  • Publication number: 20070287318
    Abstract: A connector comprises a first housing having a shoulder on an end thereof. A second housing has a first thread on an end thereof. A coupling nut engages the shoulder and has a second thread on an end thereof, where the second thread is engageable with the first thread. Engagement of the first thread and the second thread brings the first housing and the second housing into an operative position with no more than two revolutions of the coupling nut. A method of assembling a connector comprises providing a first housing having a shoulder on an end thereof. A coupling nut engages the shoulder. A first thread on the coupling nut engages a second thread on a second housing, and rotating the coupling nut no more than two revolutions brings the first housing and the second housing into an operative position.
