US Patent 7635816 Connector / bushing assembly for electrical junction boxes

A connector/bushing assembly for electrical junction boxes includes a nut which may receive a male conduit/connector which extends through the wall of a junction box, and a liner situated within the nut. The nut receives the male connector within a nut junction end situated opposite from a nut entry end. The liner is received within the nut entry end to extend toward the nut junction end, and includes a floating portion near the nut junction end, with the floating portion defining a cylinder spaced from the inner diameter of the nut junction end so that the (cylindrical) male connector can be received within the nut junction end between the floating portion and the nut junction end.
