Abstract

An electrical device includes a circuit board having upper signal contacts and at least one upper ground contact along an upper surface of the circuit board. The electrical device also includes a communication cable including a differential pair of signal conductors, a shield layer that surrounds the signal conductors, a drain wire electrically coupled with the shield layer, and a cable jacket that surrounds the shield layer and the drain wire. Each of the signal conductors has a wire-terminating end engaged to a corresponding signal contact of the circuit board. The wire-terminating ends project beyond a jacket edge of the cable jacket. An upper ground-terminating component electrically couples to the upper ground contact having a main panel with a connective terminal electrically coupled to the drain wire.
