Abstract
A grommet for sealing a first aperture formed in a splice enclosure includes a body that is receivable within the first aperture, and is subjected to a compressive force exerted by a sidewall of the splice enclosure defining the first aperture while the grommet is installed within the first aperture. The body defines a passage extending from a first end of the body to a second end of the body. A collar is coupled to a sidewall of the body defining the passage. The collar defines a second aperture that is closed as a result of the compressive force exerted on the sidewall. The collar is deformable to receive the cable within the second aperture while the grommet is installed within the first aperture to seal an interface between the collar and the cable.

A grommet for sealing a first aperture formed in a splice enclosure to receive a cable extending into the splice enclosure, the grommet comprising:
- a body formed from a first material that is receivable within the first aperture formed in the splice enclosure, the body being sized to be subjected to a compressive force exerted by a sidewall of the splice enclosure defining the first aperture while the grommet is installed within the first aperture, wherein the body defines a passage extending through the body from a first end of the body to a second end of the body;
- and
- a collar formed from a second material, different than the first material, coupled to a sidewall of the body defining the passage, the collar defining a second aperture extending through the collar from a first end of the collar to a second end of the collar, wherein the second aperture is closed to a zero diameter while the cable is not received within the second aperture as a result of the compressive force exerted by the sidewall of the splice enclosure, wherein the collar is deformable from the zero diameter to receive the cable within the second aperture while the grommet is installed within the first aperture to seal an interface between the collar and the cable.
A splice enclosure comprising:
- a housing defining an interior space;
- a cap provided to the housing to seal the interior space, wherein the cap defines a first aperture through which a cable extends between an ambient environment and the interior space;
- and
- a grommet that seals a space between a sidewall of the cap that defines the first aperture and an exterior surface of the cable extending into the interior space, wherein the grommet comprises:
- a body having an external periphery that is receivable within the first aperture, the external periphery of the body being sized to be subjected to a compressive force exerted by the sidewall of the cap while the grommet is installed within the first aperture, wherein the body defines a passage extending through the body from a first end of the body exposed to the ambient environment to a second end of the body exposed to the interior space while the grommet is installed within the first aperture, and
- a collar coupled to a sidewall of the body defining the passage, the collar defining a second aperture extending through the collar from a first end of the collar to a second end of the collar, wherein the second aperture is closed to form a water-tight seal at atmospheric pressure while the cable is not received within the second aperture as a result of the compressive force exerted by the sidewall of the cap, wherein the collar is deformable to receive the cable within the second aperture while the grommet is installed within the first aperture to seal an interface between the collar and the cable.
A splice enclosure comprising:
- a housing defining an interior space;
- a cap provided to the housing to seal the interior space, wherein the cap defines a first aperture leading from an ambient environment to the interior space;
- a cable extending through the first aperture between the ambient environment and the interior space;
- and
- a grommet installed within the first aperture to seal a space between an external surface of the cable and a sidewall of the cap defining the first aperture, the grommet comprising:
- a body having an external periphery that is subjected to a compressive force exerted by the sidewall of the cap, wherein the body defines a passage extending through the body from a first end of the body exposed to the ambient environment to a second end of the body exposed to the interior space, and
- a collar coupled to a sidewall of the body defining the passage, wherein the collar defines a second aperture extending through the collar from a first end of the collar to a second end of the collar, wherein the second aperture closes as a result of the compressive force exerted by the sidewall of the cap and is deformed to receive the cable and seal an interface between the external surface of the cable and a sidewall of the collar defining the second aperture, wherein the body has a body thickness between the first end of the body and the second end of the body, the collar has a collar thickness between the first end of the collar to the second end of the collar, and the collar thickness is less than the body thickness.
