Electrically enhanced wiring block with break test capability

摘要

An electrically balanced wiring device (100) comprises first and second rows (110 and 112) of connector blocks (108) including beam contacts for transmission lines. A row (116) of connecting strips (114) is located between the first and second rows (110 and 112) of connector blocks (108). The connecting strips (114) include a first and second set of contacts co-operating to define defeatable electrical connections in said connecting strips. The connector blocks (108) and connecting strips (114) are mounted on a circuit board (106). A circuitry on the circuit board (106) connects the contacts of the connector blocks in the first row (110) to the contacts of the first set in the connecting strips (114) and the contacts of the connector blocks in the second row (112) to the contacts of the second set in the connecting strips (114). The circuitry on the circuit board (106) is configured so as to substantially restore electrical balance to the transmission lines wherein cross talk originating from said first and second connector means is reduced.
