Abstract
A cable retractor enclosure having a weighted cable pulley and cable pulley guide rails. The cable pulley is rotatable about a pivot and configured to translate along grooves when a cable wrapped underneath is extracted from the cable retractor enclosure. The cable extends outside of the retractor enclosure from its upper end and provides a cable end plug that sits within a retractor module insert. Weights may be attached to the cable pulley in order to leverage gravitational forces, which result in a bias causing the cable to retract back into the enclosure. Friction forces against the extracted cable can be used to prevent the gravitational bias the cable pulley exerts (retraction forces) on the cable by bending the cable to lay flat onto a table surface.
