Abstract
A system of flexible conduit and fittings useful particularly, though not exclusively, for conveying, supporting and connecting electrical service cables and wires. The system includes a corrugated, synthetic resin conduit which is flexible and mechanically strong, connector sleeves for clampingly engaging sections of the corrugated conduit in end-to-end relation, and hanger sleeves for clampingly engaging the conduit and suspending it from a wall or similar surface. A novel electrical outlet box is provided and includes internally toothed conduit-receiving inlet fittings for securely engaging an end of the conduits in inlets to the box.
Claims2
A connector clamp for interconnecting a pair of conduits in end-to-end relation comprising:
- a first body portion having a semicylindrical internal wall;
- a radially inwardly projected arcuate, semicylindrical stop rib located on said internal wall intermediate the ends thereof;
- an undercut groove on the outer side of said first body portion and extending substantially parallel to the axis of said semicylindrical internal wall;
- a second body portion having a semi-cylindrical internal wall;
- hinge means joining said body portions to each other for movement from an open position to a closed position in which said semicylindrical walls form a cylindrical hollow space inside said first and second body portions;
- an elongated locking band having one of its ends secured to said second body portion at one of its longitudinal edges;
- a latching rib on the other end of said locking band is dimensioned for snap engagement with said undercut groove;
- and
- radial moveable means in the wall of said second body portion engaged by the inner surface of said locking band to force said moveable means inwardly to engage conduits placed within said cylindrical hollow space in end-to-end relation when said body portions are in said closed position and said locking band is wrapped around the outer side of said body portions with said rib snap engaged with said groove.
