ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to splices for severed electrical wires, especially in hand-held appliance tools, such as drills, sanders, saws, and the like.
BACKGROUND OF THE INVENTION
Especially in an industrial environment and to a lesser extent in commercial and home environments, extension cords or machine tool power cords are severed or damaged. The damage is usually confined to a small area, as would be the case of a sharp object falling on a power cord. A heavy-duty line cord is expensive. Normal wire nut and tape splices are not safe and reliable substitutes for replacement of the entire power cord.
OBJECTS OF THE INVENTION
The object of this invention is to provide a safe, inexpensive and easy to use splice to restore a heavy-duty line or extension cord to normal use. The construction of the splice insures good low electrical resistance connections, high mechanical pull-put resistance, rugged encasement, and the ability to waterproof the splice.
SUMMARY OF THE INVENTION
A splice connector includes a top cover connected to a lower section, by a hinge or by at least one fastener, providing a hollow interior for insertion of severed portions of an electrical cord therein. The severed portions are clamped therein and connected to an electrically conductive connection, such as a terminal block. Preferably the splice connector includes sealed entry holes for the severed cord wire sections, to keep the splice connector waterproofed and safe.
