Abstract
A cord reel device (1) for connecting a signal source (A) to a remote device (B, C) comprises a spool (2) rotatable on an arbor (18), the spool (2) having an inner chamber (6) and an outer trough (8). A retractable cord (10) is removably held in the trough (8). A spring (220) for urging the rotation of the spool (2) in a direction to retract the cord (10) is held in the inner chamber (6). The inner cable (24) is electrically connected to the retractable cord (10). The cord reel (1) of the invention may preferably include EMI-RFI shielding (112), and may find particular utility in applications requiring a substantially miniature cord reel, such as with a cellular telephone or the like.
