Abstract
Abstract A cable termination assembly has a staggered stripped cable insulation pattern to enhance the electrical isolation of plural ground isolation conductors from one or more signal conductors in the assembly, and a stepped crimp pattern at a juncture of the cable with a molded strain relief body provides an improved strain relief interaction therebetween. The cable termination assembly is made by removing the cable insulation in a pattern that exposes plural conductors while leaving an insulation portion covering part of one of the conductors to insulate the latter from the other conductors, and the exposed conductors are coupled to electrical contacts while the insulation portion left behind helps to assure the electrical isolation of the conductors from each other. The cable insulation is deformed to cause relatively raised and recessed portions in the same and a strain relief body is molded directly to the insulation with at least a portion of the molded strain relief substantially filling the space within at least one of the recessed portions. A machine prepares the cable for use in the cable termination assembly by partially removing insulation from such cable in a predetermined pattern and crimping the cable.
