High speed bypass cable for use with backplanes
First Claim
1. An improved bypass cable assembly for connecting a chip to a backplane, comprising:
- a cable, the cable including multiple wires, each wire having an insulative body portion with a pair of signal conductors extending lengthwise through the insulative body portion, the pair of signal conductors being separated by a first spacing, and a conductive shielding member surrounding the insulative body portion, each wire having opposing first and second free ends; and
a connector, the connector including an insulative frame member that supports a plurality of conductive first and second terminals in at least one row, each of the first and second terminals including contact and tail portions disposed at opposite ends thereof, the contact and tail portions being interconnected by respective terminal body portions, the wire conductors being attached to corresponding ones of the first terminal tail portions and the shielding member being attached to the corresponding ones of the second terminal tail portions, the first and second terminals being further arranged in a pattern, whereby pairs of the first terminals in the row are separated from other pairs of the first terminals by at least one intervening second terminal, the first terminal tail portions being spaced apart from each other in a spacing intended to maintain an approximate spacing of the cable wire free ends terminated thereto.

Abstract
A cable bypass assembly is disclosed for use in providing a high speed transmission line for connecting a chip, or processor mounted on a circuit board to a backplane. The bypass cable assembly has a structure that maintains the geometry of the cable in place from the chip to the connector and then through the connector. The connector includes a plurality of conductive terminals and shield members arranged within an insulative support frame in a manner that approximates the structure of the cable so that the impedance and other electrical characteristics of the cable may be maintained as best is possible through the cable termination and the connector.

18. A connector for connecting a plurality of wires to an opposing connector, each wire including a pair of signal conductors extending lengthwise therethrough in an insulative body, the pair of signal conductors being spaced apart from each other in a first spacing, and a grounding shield extending over an exterior surface of the wire insulative body and being spaced a second spacing from said wire signal conductors, the connector comprising:
-
an insulative connector body defining a connector mating area, body area and termination area; and a plurality of conductive terminals, each terminal including a mating portion disposed in the mating area of the connector body, a body portion disposed in the body area of the connector body and a tail portion disposed in the termination area of the connector body, the terminals including first terminals for transmission of signals from the wire signal conductors and second terminals for grounding the wire grounding shield, the terminals being supported the connector in separate rows of terminals and being arranged in each row in pairs of signal terminals and at least one ground terminal interposed between each pair of signal terminals. - View Dependent Claims (19, 20)
