Abstract
A non-conductive plastics junction box for connecting at least two cables has an internal conductive continuity plate integral with a base of the box. The plate has a base panel with at least one lug arranged to extend outwardly and externally of the base to provide an earthing terminal to ground, and side panels arranged to overlie side walls of the base in which entry ports are formed to receive cable glands for the respective cables. The continuity plate is in electrical contact with the glands and provides a continuous earthing path from the cables to the earthing terminal(s).
Claims20
A junction box having a base and a cover adapted to be secured together to provide an enclosure for electrical connections of at least two electric cables, said cover being of a non-conductive plastics material and said base being of a non-conductive plastics material and having integrally moulded therein a conductive continuity plate, said continuity plate having at least one lug extending outwardly and externally of said base to provide an earthing terminal to ground, and said continuity plate extending to the regions of entry ports formed in said base through which electric cables are to extend with said continuity plate being exposed at said regions for electrical contact with a cable gland fitting engaged with the cable and said entry port, the arrangement being such that in the assembly, there is a continuous earthing path from the respective cables through said continuity plate to said earthing terminal.
A junction box providing an enclosure for electrical connections of at least two electric cables, said junction box being of non-conductive plastics material and having an integral conductive continuity plate located within said enclosure for electrical contact with a cable entry fitting mounted on said junction box, said continuity plate having at least one lug extending outwardly and externally of said junction box to provide an earthing terminal to ground.
