Device for transmitting energy through electric wire or optical cable wound on drum

摘要

A device for transmitting signals or energy between a reel wound multi-core or multi-conductor cable and a stationary terminal unit without the use of a sliding connector. Dummy bobbins are provided coaxially with and rotatable with the winding reel with individual strands or conductors extending onto the winding surface thereof and wound thereupon. As the main cable is played out, the individual strands or wires are unwound from the dummy bobbins and then taken up by storage devices. In one embodiment, the storage devices are a second set of bobbins while in another embodiment the storage devices are constituted by stationary bundle receiving devices with pinch rollers provided for urging the individual strands or wires into the bundle receiving devices.
