ABSTRACT:
Apparatus for preventing the undesirable twisting of an input wire or cable includes a housing having an input and output port and having an internal hollow. Located within the hollow is a ball bearing assembly having an inner and outer race electrically connected to the other by means of the roller bearings. The outer race is rigidly secured to the housing while the inner race has a central aperture into which aperture is positioned a partial circular conductive plate. An input wire is electrically connected to the outer race while an output wire is electrically connected to the plate associated with the inner race. Thus the bearing assembly provides a connection between the wire connected to the outer race and the wire connected to the inner race. The conductive plate is associated with an elongated rod which rod is coupled to adjacent bearing assemblies via their associated plates. Each bearing assembly is associated with an individual input and output wire where the output wires as coupled to the conductive plates all rotate the same amount due to the rod to compensate for and to prevent undue twisting of an output line cord of that associated with a telephone subset or other device.
