Abstract
Methods of coiling a conductor - for example a telephone cord - in a manner that imparts no net twist on the conductor, thus preventing the conductor from twisting or kinking. One technique involves coiling the conductor in one sense followed by a turn in the opposite sense. The conductor may adopt for example a helical structure or a planar structure. In a second technique, the conductor is twisted along its length concomitantly winding the twisted length in a generally helical path.
Claims
1. A method of coiling an electrical conductor to provide an extensible lead having a series of turns, in which turns in one axial sense are interposed with turns in the opposite axial sense so that no net twist is imparted to the conductor.
2. A method according to Claim 1, wherein additional turns of opposite axial sense are superimposed upon a generally helical coil structure.
3. A method according to Claim 1, wherein additional turns of opposite axial sense are superimposed upon a generally planar structure.
4. A method according to Claims 2 or 3, wherein said additional turns are superimposed alternately.
5. A coiled electrical conductor formed so as to provide a resiliently extensible lead, having turns in one axial sense interposed with turns in the opposite axial sense, such that substantially no net twist is imparted to the conductor.
6. A conductor according to Claim 5, wherein additional turns of opposite axial sense are superimposed upon a generally helical coil structure.
7. A conductor according to Claim 5, wherein additional turns of opposite axial sense are superimposed upon a generally planar structure.
8. A conductor according to Claims 6 or 7, wherein said additional turns are superimposed alternately.
9. A method of coiling an elongate electrical conductor so as to provide a resiliently extensible lead, comprising twisting the conductor along its length concomitantly with winding the twisted length in a generally helical path such that no net twist is imparted to the conductor.
