High speed bypass cable for use with backplanes

摘要

A cable bypass assembly is disclosed for use in providing a high speed transmission line that connect a chip, processor or circuitry mounted on a circuit board to other similar components. The bypass cable assembly has a structure that allows for low loss between a first body and a connector that includes a second body. The connector includes a plurality of conductive terminals arranged in a manner that allows the impedance and other electrical characteristics of the cable to be maintained in a desirable manner through the cable bypass assembly.

主权项

1. A bypass cable assembly, comprising:
a first body formed of an insulative material supporting a first pair of terminals and a second pair of terminals, the pairs of terminals configured to be terminated to a circuit board; at least one cable supporting a first pair of signal conductors and a second pair of signal conductors, the at least one cable supported by the first body, the first pair of terminals and the second pair of terminals respectively coupled to the first and second pair of signal conductors; and a connector including a second body formed of an insulative material, the connector configured to mate to another connector, the second body supporting a first terminal, a second terminal, a third terminal and a fourth terminal that are in a row, each of the terminals in the row including a contact and a tail, the contact and tail disposed at opposite ends thereof, the signal conductors of the at least one cable coupled to tail portions, wherein the first and second terminal are adjacent and form a third pair of terminals and the third and fourth terminal are adjacent and form a fourth pair of terminals and a connector ground terminal is positioned between the third and fourth pairs of terminals, wherein the bypass cable assembly is configured to support 10 GHz signaling.
