Cable grounding system for an information handling system
View Patent ↗An information handling system may include a first member, a second member hingedly coupled to the first member via a hinge, a coaxial cable, and a grounding jacket. The coaxial cable may have a ground sheath and a signal wire internal to the ground sheath, wherein an axis of the signal wire is substantially parallel to a rotational axis of the hinge and wherein the coaxial cable comprises an exposed portion in which the ground sheath is exposed externally to the coaxial cable. The grounding jacket may be mechanically coupled to the first member and the second member, wherein the grounding jacket may be configured to mechanically support the coaxial cable and electrically couple to an electrically conductive portion of at least one of the first member and the second member and to the ground sheath at the exposed portion in order to create an electrically conductive path between the ground sheath and the electrically conductive portion via the grounding jacket.
