Abstract
A cord reel assembly is provided which maintains a length of stationary wire and a length of shielded retractable wire around a spool. The assembly dispenses the retractable wire as an attached handset is extended away from the assembly, while the stationary wire is concurrently being wound. A portion of the stationary wire internal to a housing enclosure is unshielded, while a portion extending outside the housing enclosure is shielded. The unshielded stationary wire is shielded by applying conductive paint or electroplating to the housing enclosure, thereby reducing EMI emissions. A spring cover retains a recoil spring and provides a bearing surface against a spindle member. The winding direction of the stationary and retractable wires is chosen, and the stationary wire conductors are arranged with shield ground wires, such that EMI emissions are reduced.
