ABSTRACT:
A strain relief apparatus for relieving strain on a cable of an electrical device having a housing with a notched-out portion therein. The strain relief apparatus is generally planar and is mounted directly into the notched-out portion. The strain relief apparatus has a U-shaped channel which is dimensioned to provide an interference fit with the cable after the cable is mounted therein. The design of the strain relief apparatus introduces bends in the cable to further facilitate strain relief if, for example, the cable is accidentally jerked or pulled.
