High performance cable with faraday ground sleeve
An improved termination assembly for a multi-wire cable is disclosed. The assembly includes a carrier member that includes wire nest portions spaced along a base portion. The wire nest portions are hollow enclosures that contact the exterior grounding shields of the cable wires so as to electrically interconnect all of the cable wires together through a common ground.
1. A cable connector, comprising:
a multi-wire cable, the multi-wire cable including a plurality of electrical wires, each electrical wire including a pair of conductors encased in an insulative covering and an associated grounding shield extending over an exterior of the insulative covering;
a connector housing, the connector housing including a hollow interior, the hollow interior including a circuit card disposed therein, the circuit card including a plurality of termination contact pads connected to circuitry thereof and an exposed ground plane, a free end of the multi-wire cable being received in a portion of the connector housing proximate the circuit card; and
a carrier member for holding the electrical wires, as a group, in a preselected position and further interconnecting the grounding shields together, the carrier member including a conductive body portion including a preselected width sufficient to permit arrangement of all of the electrical wires thereupon in a pattern such that adjacent electrical wire pairs are separated by intervening spaces, and a plurality of nest portions defining a plurality of hollow enclosures, each nest portion receiving one of the electrical wires, the nest portions being interconnected together by base portions, the base portions including mounting surfaces that contact the ground plane, the nest portions including contact surfaces for contacting the grounding shields, the mounting surfaces being disposed between adjacent nest portions.
2. The cable connector of claim 1 , wherein the carrier member further includes a plurality of peak and valley portions.
3. The cable connector of claim 2 , wherein each peak portion defines one of the nest portions and each valley portions defining one of the mounting surfaces.
4. The cable connector of claim 1 , wherein each nest portion is staggered lengthwise along the carrier member.
5. The cable connector of claim 1 , wherein each nest portion includes a plurality of crimping legs.
6. The cable connector of claim 5 , wherein each crimping leg is folded over onto the grounding shields.
7. The cable connector of claim 6 , wherein pairs of the crimping legs are separated by intervening slots.
8. The cable connector of claim 7 , wherein the slots permit visual inspection of solder attachment of the carrier member to the electrical wires.
9. The cable connector of claim 1 , wherein the carrier member further includes a leading edge that defines a datum line for facilitating proper positioning of the electrical wires on the carrier member.
