ABSTRACT:
One embodiment of an electrical junction assembly (10) for providing expansion and retraction of an electrical outlet or connector (20) comprises a main housing (12) having a conduit box (16), with a flexible conduit (18) interconnecting the connector (20) and box (16). Incoming wires (23, 24) are received within an insulated connector receptacle (28) and thereat spliced to conductive wires (22) received within the conduit (18) and terminating at the connector (20). The conductive wires (22) are coiled within the main housing (12) so as to allow slack for purposes of expansion and retraction of the connector (20) and conduit (18). In another embodiment, electrical cable (54) is coiled around an elliptically configured center support (62) within an expansion box (50), and allows expansion through opposing conduit portions (52) with automatic retraction when external forces are removed from the conduit portions (52).
