Abstract
A grommet is attachable over an opening in an enclosure wall of an electrical device to protect electrical conductors passing through the opening. The grommet has a twist lock conduit connector that can be attached over an opening in the enclosure wall of the electrical device without the need for separate fasteners. The grommet protects the insulation of electrical conductors passing through the opening of the enclosure wall, seals the opening from its exterior environment, and provides a connection outside the enclosure wall for the attachment of a length of conduit through which the electrical conductors are passed.
Claims20
A grommet for an enclosure wall having an opening therethrough, the grommet comprising:
- a tubular base having opposite first and second ends with an interior bore passing through the base between its first and second ends, the bore having a center axis;
- a disk extending around the base and projecting outwardly from the base between the base first and second ends;
- a tab projecting outwardly from the base adjacent the base second end, the tab having a surface that faces toward the disk, the tab surface has opposite first and second edges and the tab surface at the first edge is axially closer to the disk than the tab surface at the second edge.
A grommet for an enclosure having an enclosure wall with an opening therethrough, the opening having a major axis and a minor axis, the major axis having a dimension that is larger than a dimension of the minor axis, the grommet comprising:
- a tubular base having opposite first and second ends with an interior bore passing through the base between its first and second ends, the bore having a center axis;
- a disk extending around the base and projecting outwardly from the base between the base first and second ends;
- and
- a tab projecting outwardly from the base adjacent the base second end to a distal end of the tab, the tab distal end being spaced a first distance from the base center axis that is less than half of the enclosure wall opening major axis dimension and greater than half of the enclosure wall opening minor axis dimension.
