ABSTRACT:
For use in a portable electric appliance, that is cord-connected to internal electric terminals by multiple conductors, there is provided a strain relief assembly between the cord and appliance that has a housing chamber in the appliance at the cord entrance. A formed saddle is secured to the chamber and has spaced ears defining a preferably slanted passage therebetween aligned with the lay of the cord and which holds the cord conductors as the cord enters the appliance. There is provided a formed clamp fitting over the saddle and removably attached thereto. The clamp has a toothed flexible strap-like extension in a generally U-shape connected at one end of the clamp and freely hanging at the other end with downward opening teeth at the free end which are disposed into the passage against the conductors to jam them in the passage. A wedge means is provided on the clamp opposite the extension and a cover is over the entire strain relief assembly so that the flexible extension is forced by the wedge into biting engagement with the conductors in the passage, the wedge and free flexible extension permitting the strain relief to be used with different sized conductors.
