Abstract

A coaxial cable commonly has a central signal conductor, a surrounding dielectric, an outer conductive ground shield, and an outer dielectric jacket. Several coaxial cables can be given a common outer dielectric structure to form a flat ribbon cable. For electrically connecting a ribbon cable to other components, the ends of the coaxial cables are stripped to expose a short length of the signal conductor and a wire- like length of the conductive shield. A contact is attached to the exposed end of the signal conductor.

Connector for Ribbon Coaxial Cable With One Ground Contact for Each Signal Contact and With Electrical Shielding Up to the Receiving Connector

A coaxial cable commonly has a central signal conductor, a surrounding dielectric, an outer conductive ground shield, and an outer dielectric jacket. Several coaxial cables can be given a common outer dielectric structure to form a flat ribbon cable. For electrically connecting a ribbon cable to other components, the ends of the coaxial cables are stripped to expose a short length of the signal conductor and a wire- like length of the conductive shield. A contact is attached to the exposed end of the signal conductor.

In an improved ribbon cable and connector assembly, a conductive tube is positioned at the end of the coaxial cable with one end extending slightly over the unstripped end of the dielectric and the other end extending slightly beyond the end of the contact. The exposed length of the shielding conductor is electrically connected to the inside wall of the tube, and the tube electrically shields the center conductor and the contact. These components are held together by a plastic encapsulent.

The end of the ribbon cable with the center contacts and the conductive tubes is placed in a plastic housing structure with the contacts and the ends of the tubes extending beyond the end of the housing. The housing is made of plastic and is metalized for electrical shielding. The array of contacts is held in a fixture while the components in the housing are encapsulated. The housing structure is thin and flat, and several flat housings are hel...
