Abstract The invention is designed for use in an electric appliance having an electric cord secured to terminals therein by a portion having separated conductors extending outside the appliance and using a strain relief means clamping the conductors and adapted to mount in the appliance to reduce stress on the terminals. In this environment there is provided an improvement in the insulating structure of the cord that comprises at least a single insulator on one conductor extending primarily only from the clamping means away from the terminals and this insulator may be a glass tape. A second heavier glass sleeve type insulator is provided on the other conductor and its extends primarily only from the clamping means toward the terminals so that the clamping means, which may be a metal clip, is squeezed on the insulators which overlap within the clip so that only about half as much insulation is required as normal. The invention is especially adaptable to conductors covered with a molded chlorosulphonated polyethylene covering.
For use in an electric appliance having an electric cord secured to terminals therein by a cord portion having separated conductors extending outside said appliance and a strain relief means clamping said conductors and adapted to mount in said appliance to reduce stress on the terminals, the improvement in the insulating structure of said cord comprising, at least a single insulator on one conductor extending primarily only from said relief clamping means away from said terminals, and a second insulator on the other conductor extending primarily only from said relief clamping means toward said terminals, said relief clamping means securing each insulator at opposite ends thereof to the conductors.
