Abstract: A method of stranded electrical wire connection involves stripping the insulation off the ends of stranded wire, inserting a metallic barrel member over the ends of the wire, applying ratcheting pressure to the barrel member to compress the barrel member over each end of the stranded wires, and then applying constant, irreversible ratcheting pressure to the wire containing barrel to substantially eliminate the spaces between the strands and to form a permanent barrel to wire connection between the lengths of wire. A shrink tube with an inner layer of adhesive is positioned over the permanent connection and the shrink tube, with its layer of adhesive, is heated, thus substantially eliminating any space between the shrink tube and the permanent connection. Utilizing the method of the present invention results in a permanent, waterproof connection between the stranded wire which eliminates all expansion and contraction within the permanent connection during use.

Abstract: A method for reducing crosstalk between a plurality of wires in a network cable using a network cable jack that includes a printed circuit board (PCB) for balancing both inductive and capacitive coupling. The method includes using two distinct inductance zones separated by a neutral zone. Significant gains in degrees of freedom are achieved for designing PCB trace patterns in which a pair of inductive coupling zones jointly offset the inductive coupling caused by a specification plug and the jack contacts, both in magnitude and phase angle. Further, using distinct inductance zones offers more freedom regarding the placement of capacitive plates for use in capacitance balancing as well as the placement of terminals and insulation displacement contacts. Although the magnitude of a capacitive coupling is determined by the length of the capacitor plates parallel to current carrying traces, the approach allows capacitive and inductive coupling to be balanced independently.
