Abstract
A cable gland including an entry component including an inner surface with an abutment, a backnut removably attachable to the entry component, a cavity extending through the entry component and the backnut, and a grounding device configured to rest against the abutment. The grounding device includes a rim, an inner edge, and a plurality of fingers extending inward and downward from the inner edge. The grounding device is made of a conductive material, such as spring steel.
Claims16
A cable gland, comprising:
- an entry component including an inner surface with an abutment;
- a backnut removably attachable to the entry component;
- a cavity extending through the entry component and the backnut;
- and
- a grounding device including:
- an upper rim having a flat lower surface configured to rest in a fixed position against the abutment,
- an annular intermediate portion, radially inward of the upper rim, with an inner edge radially inward of and below the upper rim and an annular outer surface below and extending perpendicular to the flat lower surface of the upper rim configured to engage against the inner surface of the entry component, and
- a plurality of fingers extending inward and downward from the inner edge;
- wherein the grounding device is comprised of a conductive spring steel material,
- wherein the annular intermediate portion includes an angled portion adjacent to the plurality of fingers, and
- wherein each of the plurality of fingers are configured to flex outward to receive a cable and maintain inward pressure on the cable creating an electrical ground path from the cable to the grounding device.
