US 2015/0311642 A1 · PADDLE CARD ASSEMBLY FOR HIGH SPEED APPLICATIONS

Abstract

A paddle card assembly is disclosed for use in providing a high speed transmission line for connecting electronic devices together. The paddle card takes the form of a circuit board that has two distinct portions, a base portion to which wires of a cable are terminated, and an extension portion that extends rearwardly toward the cable wire in order to extend between sets of wires. The extension portion has one or more ground plane layers formed therewith and supported thereby and as such, the extension portion places a ground plane in the termination area of the connector, rear of the trailing edge of the paddle card to provide shielding between pairs of wires on opposite sides of the paddle card where the cable shields are cut back. The extension portion may have either a reduced thickness, or wire-receiving channels formed therein which accommodate portions of the wires of the cable.

Dependent claims

An improved cable assembly, comprising:

a cable, the cable including a plurality of wires, each wire including a conductor surrounded by an insulative covering and pairs of the wires being wrapped together in an outer shielding member, the conductors of each wire extending past a leading edge of the insulative covering to define free termination ends of the wires, and the outer shielding member having a leading edge spaced rearwardly from the insulative covering free ends;
a circuit board having opposite leading and trailing edges and opposite first and second surface, the circuit board including two distinct portions:
a first portion containing a plurality of termination contact pads for connecting circuitry of the circuit board to the wire free ends, and
a second portion extending from and spaced apart from the circuit board first portion, the second portion extending rearwardly from the termination contact pads, the cable wire free ends terminating to the termination contact pads;
and
a connector housing enclosing the circuit board and a portion of the cable.

3 more elements

A circuit board assembly for use in a high speed cable connector, the assembly comprising:

a cable, at least two pairs of dedicated cable wires extending lengthwise through the cable, each cable wire including a signal conductor enclosed by an associated dielectric covering, each signal conductor having a free end that extends past a respective end of its associated dielectric coverings, and at least one conductive shield extending lengthwise through the cable and substantially enclosing the cable wires;
and
a circuit board having opposing first and second surfaces, the circuit board including a base portion with a plurality of contact pads disposed thereon, and an extension portion extending from the base portion rearwardly of the base portion contact pads for a given distance, the extension portion supporting at least one ground plane;
wherein the signal conductor free ends terminate to the circuit board base portion contact pads such that the ends of the dielectric coverings or each wire pair are disposed rearwardly of contact pads, whereby said the extension portion extends rearwardly between pairs of cable wires.
