US Patent:

39834573, Sep 28, 1976

Filed:

Feb 18, 1976

Appl. No.:

5/659182

Inventors:

Sidney R. Smith - Buckeye AZ

Assignee:

Hughes Aircraft Company - Culver City CA

International Classification:

H05K 504

US Classification:

317 99

Abstract:

An improved seizure device for connecting coaxial cable transmission lines to electronic devices is disclosed. According to the invention, the center conductor of the coaxial cable is inserted in an opening between two tines of a conductive post which is electrically connected to the electronic circuitry. The outer conductor of the coaxial cable is inserted through a serrated ferrule. A single clamping nut provides a force which acts through the serrated ferrule, a guide clamp and a tapered seizure post holder to simultaneously clamp the inner and outer conductors for electrical and mechanical contact.

Abstract:

A cable system subscriber tap equipped with a rotating center conductor seizure apparatus for mechanically and electrically seizing the center conductor of a coaxial cable. The improved seizure apparatus provides a rotating clamp held within an insulating structure mounted in the tap adjacent each of the orthogonally arranged pairs of cable access ports, the seizure clamp being rotatable between orthogonal positions within its insulating structure to alternately seize the center conductor of a coaxial cable inserted through either one of the pair of access ports without diassembly of the clamp or seizure apparatus. The improved clamp provides a nonshear seizure of the center conductor that is both quickly and easily changed in the field. It further includes a conductive, spiral spring contact held within a countersunk axial bore in the clamp and rotatable therewith while maintaining mechanical and electrical connection to the contact pin of a printed circuit board. Improved methods for installing and for changing cable installations are also disclosed using the same.

Abstract:

The present invention is an improved Yagi-Uda style antenna. Primarily, the present invention provides that at least two driven elements are spaced approximately 0. 1. lambda. apart from each other. The driven elements are forced into a critical couple mode by electrically connecting the two driven elements with a matched phasing delay line. The phasing delay line retards the phase current sufficiently to, coupled with the specified element separation, satisfy both the endfire condition and the Hansen-Woodyard condition. This provides for increased directivity and gain, and deep nulls in the field strength. The at least two critically coupled elements compromise at least a first driven element, which is the primary broadcast element, and a second driven element, which is a driven reflector element. The reflector element acts to augment field strength in a direction toward the first driven element and reduce field strength in a direction away from the first driven element. The present invention may include the use of at least one parasitic director elements.
