Abstract
A wiring base for a bar code scanner or the like provides a conductive housing open at one face for connecting cables at various screw terminals to a circuit board providing signal processing for the signals and permitting various different-connections of the cables. The shields of the cables pass into the conductive housing to be terminated on conductive housing thereby enlisting the conductive housing as a shield around all the cables. Attachment of the scanning head to the upper face of the wiring base closes the housing to be free from the egress of dust or liquid and completes a Faraday cage around the connections while connecting two multi-pin connectors one within the base and one within the scanner, communicating the signals to the scanner. A visual indicator attached within the conductive housing indicates the presence of power and its polarity prior to connection of the scanning head to the conductive housing.
