ABSTRACT:
A strain relief for an electrical conductor cord is disclosed for distributing a bending stress acting on the cord. The strain relief includes a head portion and a flexible tail portion molded about a conductor having a major transverse axis of greater dimension than its minor transverse axis. A bending force acting on the cord in a direction to effect bending about a bend axis nonparallel to the major transverse axis of the cord induces both bending and torsional movement of the strain relief so as to distribute the flexure strain over the length of cord within the strain relief and thereby increase the flexure life of the cord.
