Abstract
A system is provided for mounting shielded cables in a manner to provide good EMI (electromagnetic interference) shielding, which facilitates terminations and enables field replacements. The system includes a backshell housing having a conductive shell (16, FIG. 1) holding an insert, the housing also having a conductive cover (24) that mounts over the rear end of the shell and that has rows of holes (46) that each pass a prepared cable end (44). After the cables are inserted through the cover holes, a ferrule assembly is attached to the cable. The ferrule assembly (60) includes a ferrule (40) crimped to each cable, a conductive elastomeric seal (50) lying closely about each ferrule crimped portion, and a clip (56) with a rear end that abuts the seal. A grating (62) with parallel beams is inserted sideways between ferrule assemblies to organize them into rows and to abut the forward ends of the clips. When the cover is attached to the shell, the clip compresses the seal against the cover and against the ferrule.
