Abstract
Abstract A universal connector of the "D"-type for use on the ends of cables connecting electronic equipment, the connector permitting ready customizing for particular applications. A circuit board is inserted, in one embodiment within the hood shield of the "D"-type connector that has a terminal strip for the mechanical joining of wires of the cable. This circuit board also has junction points for being joined, as by soldered connections, to pins of the connector, and fuse links joining the terminal strip and the junction points. In another embodiment, the circuit board and its components is within an auxiliary body, with this auxiliary body being connected to the "D"-type connector via pigtail cable. The connector is customized by electrically destroying (blowing) selected fuse links by passing current therethrough whereby the remaining fuse links form selected circuit paths between the pins of the connector and the cable. Provision is made to sufficiently isolate each fuse link so as to permit the blowing of the selected individual fuse units. This protection is afforded by resistive units at selected locations associated with the fuse links.
