Patent number: 4280749Abstract: An electrical contact for a coaxial cable (3) includes a tubular shell (17, 35) forming an outer contact element (19, 37) and an inner socket (13) or pin (31) type contact element having a pair of laterally spaced resilient fingers (49, 63) housed in a tubular insulator (15, 33). As the tubular insulator (15, 33) is inserted into the tubular shell (17, 35), wedge blocks (85, 107) extending laterally through slots (95, 113) in the walls of the insulator, compress the resilient fingers of the contact element against the center conductor of the cable. The cable shielding (7) is splayed back over a resilient sleeve (115) at one end of a bushing (21) which slides onto the end of the cable. This sleeve is split longitudinally and is resilient such that it may be compressed radially to insert it into the tubular shell (17, 35) where it expands to press the splayed back cable shielding into contact with the tubular shell.Type: GrantFiled: October 25, 1979Date of Patent: July 28, 1981Assignee: The Bendix CorporationInventor: Valentine J.

Patent number: 4279458Abstract: A releasable electrical connector consisting of a connector plug mating with a corresponding connector receptacle which may be disconnected by a separating force applied to a surrounding operating sleeve and the connectorl receptacle. The operating sleeve is shifted axially by the separating force against the bias of compression springs to a release position. The springs are received within grooves formed along the exterior of a segmented spring retaining housing, the segments forming an anchoring flange disposed within a recess formed about the connector plug. A plurality of arcuate threaded coupling segments assembled within the operating sleeve provide a threaded coupling, which segments in the nonreleasing position of the operating sleeve are positioned radially inward to mate with a corresponding thread on the receptacle and serve to create a mating force between the receptacle and plug upon rotation of the operating sleeve and to retain the connector and plug in the connected position.Type: GrantFiled: July 23, 1979Date of Patent: July 21, 1981Assignee: The Bendix CorporationInventor: Carl L.
