Abstract:
1. A universal serial bus cord reel apparatus comprising: a cable, the cable comprising a) first and second data wires adjacent to each other, and twisted around each other at approximately four twists per inch; b) a first braided shield surrounding the first and second data wires to prevent electromagnetic or radio frequency interference; c) two or more additional conductors adjacent to the shield surrounding the first and second data wires, the additional wires being twisted about the shield at approximately two twists per inch; d) a polytetrafluoroethylene cover enclosing the additional conductors and first and second data wires; and e) a second shield enclosing the polytetrafluoroethylene cover; whereby the cable has an impedance of approximately 90 ohms; a universal serial bus connector at each end of the cable; a housing; a reel attached to and rotatable with respect to the housing for accepting the cable; a spring mounted between the housing and the reel for biasing the rotation of the reel in one direction for retracting the cable; a ratchet attached to the housing for selectively restraining rotation of the reel whereby the cable may be maintained in an extended position, or retracted and wound on the reel.
