Abstract: A cable winding housing for a cable used to interconnect a computer and an external peripheral device. The housing includes a spring-operated, winding cylindrical shaft around which the cable is wound, a teeth wheel assembly superposed around the shaft, and a spring-loaded locking element configured for locking between two of the teeth on the teeth wheel, wherein the locking element is releasable from outside of the housing. When the locking element is locked into the teeth wheel, the shaft is prevented from rotating such that the cable can not be unwound from or wound into the housing. When the locking element is released from the teeth wheel, the shaft can rotate and the cable can alternatively be either wound into or unwound from the housing. The housing prevents a cable used to interconnect two devices from becoming entangled with other cables and ensures that each cable is taut and does not sag downward, thereby providing a neat connection.
