Patent number: 5490803Abstract: A method and a device is provided which allows the connection of coaxial cable termini to one another with minimum long-term loss of RFI shielding. The method comprises the removal of metal oxides from the concentric conductor portions of the two cable termini, applying a sealant to the concentric conductor termini and then connecting the central conductor termini to one another and the concentric conductor termini to one another. The device comprises a collet structure dimensioned to slip over the outside of a standard connection jack. Within the collet structure is disposed a quantity of sealant and the collet structure has at least one aperture through which sealant oozes from the collet structure to the exterior of the collet structure. When the collet structure is attached to the jack, the sealant is caused to ooze onto the concentric conductor thereby sealing the concentric conductor from the ambient.Type: GrantFiled: November 8, 1994Date of Patent: February 13, 1996Assignee: Raychem CorporationInventors: Corey McMills, John Mattis

Patent number: 5454732Abstract: An electrical connector 10 having a housing 12 containing a terminal 30 of the type adapted for insertion of an end of a wire 40,42 through a wire-receiving aperture 14,16 thereof for termination, includes a substrate 50 adhered to the outer housing surface and traversing the wire-receiving aperture with a corresponding hole 52,54 aligned therewith to permit wire insertion. The substrate may be tough elastomeric tape, and the hole is smaller than the wire diameter to tightly grip the wire insulation after wire insertion to assuredly retain sealant material within the connector upon wire withdrawal.Type: GrantFiled: January 3, 1995Date of Patent: October 3, 1995Assignee: The Whitaker CorporationInventors: Sam Denovich, James W. Robertson, Thomas J. Schuetz

Patent number: 5451169Abstract: Connectors for attachment to cables including a large number of very small flexible conductors (26) or coaxial conductor pairs (74). In a first embodiment very small contacts (36) are arrayed on a flat mating surface (28) of the connector body (22). Contacts (36) are raised slightly above the mating surface by plating conductive metal to form raised bumps (42) on one of a pair of connectors (14, 16). Insulated individual conductors (26) are placed through apertures (48) defined in a substrate acting as a template, and are fastened in place by potting material (50) before shaping the mating surface (28) of the connector body (22) or (24) is shaped. Pin and socket combinations (30, 32) are used to align mating connectors with each other.Type: GrantFiled: January 23, 1995Date of Patent: September 19, 1995Assignee: The Whitaker CorporationInventors: Scott S. Corbett, III, David F. Miller, James F. McIntire, Jerry Martyniuk, Larry L. Davis, Daniel DeLessert, Michael L. Demeter

Patent number: 5439396Abstract: A circuit breaker has ferrule type line and load terminals which clip on to portions of, respectively, input and output current buses for the breaker to permit the breaker by a mere plug-in action to be fastened to those two buses. The output current bus is provided by an adapter comprising a molded plastic case having at its top a receptacle for an end lug on a cable for distributing current from the breaker to a load, and having at its bottom a cylindrical metallic contact to which the load terminal of the breaker is or may be clipped. A metallic bus strap extends in the case from that contact to terminal means in the receptacle for connecting the upper end of the strap to such lug. The case has formed on the outside thereof a horizontal guideway into which the input current bus may be slid to thereupon be held insulated from, and fixedly fastened with, the output current bus strap in the adapter.Type: GrantFiled: September 28, 1993Date of Patent: August 8, 1995Assignee: AT&T Corp.Inventor: Jose L. Magdaleno

Patent number: 5433628Abstract: A sealing mechanism for a connector and a method of producing a connector wherein undesirable invasion of water and oil from terminals in an earth connector, an engine connector or the like can reliably be prevented. A sealing mechanism for a connector is constructed such that a plurality of transversely extending grooves are formed on the opposite surfaces of an embedding portion of a terminal extending outside of a wall portion of a connector housing 1, and the connector housing and the terminal are molded integral with each other in the presence of a sealable coating agent applied to the embedding portion. A method of producing a connector is practiced by way of the steps of applying a sealable coating agent to an embedding portion of a terminal extending from a connector housing, and Subsequently, molding the connector housing integral with the terminal in the presence of the sealable coating agent applied to the embedding portion.Type: GrantFiled: July 13, 1993Date of Patent: July 18, 1995Assignee: Yazaki CorporationInventors: Keiko Sadaishi, Kazuhiro Morishita, Toshiaki Hasegawa

Patent number: 5429697Abstract: A method is provided for sealing openings (24, 26) in a module (10). In accordance with the method, each opening is sealed by providing a readily-puncturable sealing membrane (30, 30') within the module itself to overlie each opening. Each membrane advantageously prevents a gel (28), admitted into the module, from leaking out.Type: GrantFiled: November 1, 1993Date of Patent: July 4, 1995Assignee: AT&T Corp.Inventors: Peter F. Lilienthal, II, Ivan Pawlenko
