Claims16
A bushing for a cable gland, the bushing comprising:
- a bushing body having a generally annular shape, the bushing body having an interior surface defining an opening extending through first and second axial ends of the bushing body, an exterior surface, and an axis extending through the first and second axial ends, wherein the bushing body is axially compressible;
- and
- an internal rib extending radially inward from the interior surface relative to the axis of the bushing body, wherein the internal rib is configured to move radially inward relative to the axis of the bushing when the bushing body is axially compressed to sealingly engage a cable coupled to the cable gland, wherein an inner diameter of the bushing is constant along the axis of the bushing body from the first axial end to the second axial end except for at a location of the internal rib.
A cable gland comprising:
- a gland body defining an internal passage configured to receive a cable therein;
- and
- a bushing received in the internal passage of the gland body, the bushing comprising
- a bushing body having a generally annular shape, the bushing body having an interior surface defining an opening extending through first and second axial ends of the bushing body, an exterior surface, and an axis extending through the first and second axial ends, wherein the bushing body is axially compressible;
- and
- an internal rib extending radially inward from the interior surface relative to the axis of the bushing body, wherein the internal rib is configured to move radially inward relative to the axis of the bushing when the bushing body is axially compressed to sealingly engage the cable when the cable is coupled to the cable gland, wherein an inner diameter of the bushing is constant along the axis of the bushing body from the first axial end to the second axial end except for at a location of the internal rib.
