Abstract

A rewindable electrical cable extension device includes a housing having first and second exit ports, and a cable having first and second ends defining opposing extremities of first and second contiguous cable sections having a common junction anchored to a rotating spool. The first end protrudes through the first exit port, and the second end is fixedly mounted in association with the second exit port. The first cable section is wound on a spool that is configured to rotate within the housing. The second cable section is wound in an opposite direction to the first section so that pulling on the first end unwinds and extracts the first cable section from the housing and uncoils the second cable section within the housing without rotating the second end of the cable.

Claims14

Dependent claims

A rewindable electrical cable extension device for coupling between first and second connectors, the device comprising:

a housing having first and second cable exit ports,
a cable having a first end and a second end defining opposing extremities of first and second contiguous sections of the cable,
the first end of the cable protruding through the first exit port and being configured for connection to the first connector,
the second end of the cable being fixedly mounted in association with the second exit port and being configured for connection to the second connector, and
the first section of the cable being wound in a first direction on a rotating spool that is configured to rotate within the housing,
a common junction of the first and second sections of the cable being anchored to the rotating spool, and
the second section of the cable being wound in an opposite direction to the first section so that unwinding the cable by pulling on the first end extracts the first section of the cable from the housing and uncoils the second section within the housing without rotating the second end of the cable.
