Abstract
An electrically enhanced wiring block with break test capability employs a printed circuit board which includes integrally defined transmission lines and capacitive elements designed to improve impedance characteristics and electrical balance between interconnected wiring and connecting strips and thereby optimize its transmission performance. The transmission lines consist of impedance controlled circuitry with integral capacitive elements that are provided by means of a novel use of plated through holes. The holes may be sized, spaced and interconnected in various configurations to generate the desired capacitance. Two rows of connecting blocks with a row of connecting strips therebetween are mounted to one side of the circuit board preferably by solderless connectors and are interconnected by circuitry on the circuit board. The capacitive elements are connected between selected leads of the connecting blocks and connecting strips by the impedance controlled circuitry. The circuit board is mounted onto a bracket which is itself mounted onto a wiring block base. A series of disconnect plugs are provided for breaking electrical connection between selected connecting block positions…
