Abstract

Restraining or relieving a cable (such as a power cord) coming off a wall with a helix twist wire form in wich the wire is wound onto the restraint.

Helix Cable Strain Relief

     The core idea of the invention is a Helix twisted wire form that forms a track for the cord to be put into and thereby restrained by the wireform of the helix. The cord is rotated into place inside of the invention with either a clockwise winding or a counter clockwise winding. In affect the cord is wound onto the helix wireform and is bound to it by the track of the wireform. The cord is placed into the wall socket (or rear bulkhead of a server) and the invention is either rotated down onto the cord or rotated up to the cord. With the tip of the invention located cross ways to the axis of the helix the wire can enter in either a CW or CCW motion and be retained within the invention. A different tip that comes up from the bottom only but adds more support to at the tip for the cord can also be seen to work. The helix winding of the invention being formed by being wound upon a hardened shaft of near same diameter as the cord albeit the helix wire form after forming will expand to accept cords of larger diameter within a typical cord size family. The following pictures are of the invention.
