ABSTRACT:
A sealed electrical junction box includes a sectional housing containing a chamber and having an end wall that contains at least one access passage in which is mounted a sealing bush containing a longitudinal through bore. An annular internal sealing rib on the access passage wall cooperates with a corresponding circumferential groove in the outer circumferential surface of the bush, thereby to seal the space between bush and the access passage wall. To seal the space around an inserted conductor, there is mounted on the inner circumferential surface of the bush through bore at least one integral deformable sealing lip that engages the outer circumferential surface of a conductor inserted into the bush longitudinal bore. When the bush is not in use, the longitudinal bore thereof is sealed by a cylindrical plug that is inserted into the longitudinal bore.
