Abstract
Connectors and methods for providing a seal between a conductor and a wall of an electrical enclosure that includes an opening to receive the conductor therethrough and a method for providing. A connector can include a sheath configured to surround the conductor along a length of the conductor and an anchor structure internal to the sheath. The anchor structure can include fastener openings arranged to receive a plurality of fasteners that extend through the wall and through material of the sheath, to couple the sheath to the electrical enclosure with the material of the sheath between the anchor structure and the wall of the electrical enclosure to provide a seal.
Claims19
A connector for providing a seal between a conductor and a wall of an electrical enclosure that includes an opening to receive the conductor therethrough, the connector comprising:
- a sheath configured to surround the conductor along a length of the conductor;
- and
- an anchor structure internal to the sheath, the anchor structure including fastener openings arranged to receive a plurality of fasteners that extend through the wall and through material of the sheath, to couple the sheath to the electrical enclosure with the material of the sheath between the anchor structure and the wall of the electrical enclosure to provide a seal.
A method of providing a seal between a wall of an electrical enclosure and, selectively, one or more of a first conductor having a first conductor cross-sectional area or a second conductor having a second conductor cross-sectional area different from the first conductor cross-sectional area, the method comprising:
- installing, at an opening of a wall of an electrical enclosure, a sheath with a tapering structure including a first tier having a first tier cross-sectional area and being integrally formed with a second tier having a second tier cross-sectional area, the second tier cross-sectional area being larger than the first tier cross-sectional area and the first tier being removable from the sheath to provide unobstructed access to the second tier;
- extending one or more of the first conductor or the second conductor through the sheath into the interior of the electrical enclosure;
- and
- securing the sheath to the wall of the electrical enclosure with an anchor ring nested within the sheath, so that material of the sheath is compressed between the anchor ring and the wall to form a seal between the sheath and the wall.
A method of providing a seal between a conductor with an oblong rectangular cross-section and a wall of an electrical enclosure, the method comprising:
- securing a sheath of a connector to the wall of the electrical enclosure using fasteners inserted through the wall of the electrical enclosure and into the sheath, the sheath having a tapering structure including a first tier, the first tier having a first tier cross-sectional area and being integrally formed with a second tier, the second tier having a second tier cross-sectional area larger than the first tier cross-sectional area;
- removing the first tier from the sheath before applying a flexible sealing material, to locate a receiving end of the sheath at the second tier, the receiving end having an oblong rectangular cross-section substantially equal in size to the oblong rectangular cross-section of the conductor;
- inserting the conductor into the receiving end of the sheath;
- and
- applying the flexible sealing material around an interface between the conductor and the sheath at the receiving end to seal the interface.
