Abstract: A zone distribution adapter 2 for use as a breakout or tap with twisted pair cables provides a compact configuration that can be employed as a standalone component with a cover 22 enclosing a printed circuit board assembly, or the printed circuit board assembly can be mounted in standard distribution boxes or beneath a low profile access floor. The preferred embodiments of the zone adapter printed circuit board assembly includes a twenty-five pair vertical mount electrical connector 12 soldered to a printed circuit board 8 with four-pair electrical connectors, such as right angle modular jacks 16 or punchdown blocks 20 soldered on the sides of the twenty-five pair connector. Printed circuit board traces 10 connect corresponding positions in the twenty-five pair connector 12 and the four-pair connectors 16, 20. The cover 22 includes a central channel 26 between two raised side sections 28 with an opening 24 through which the mating portion 14 of the twenty-five pair connector extends.

Abstract: This invention is directed to a fully shielded printed circuit (PC) card holder, that may be readily "snapped" into the assembly, or disassembled, as the case may be. The holder is intended to receive a PC card, where at least one end of the card is adapted to be electrically connected to an I/O type connector. The holder comprises a generally rectangular bottom cover member formed of a conductive material, corner supports integrally molded to the bottom cover member at the respective corners thereof, where each support includes a lower flange portion to which the bottom cover member is exposed. Further, a generally rectangular upper cover member is provided where the periphery thereof includes a downwardly extending flange adapted to engage the lower flange portion in electrical contact with the bottom cover member over a substantial portion of the periphery thereof.
