Racetrack grommet for optical fiber cable splice closure
First Claim
1. A racetrack grommet for providing a seal between first and second flanged closure portions wherein the closure portions define at least one opening in the end which, when the portions are assembled, allow ingress and egress of at least one cable, said racetrack grommet comprising:
- a member having first and second longitudinal sides spaced apart a distance such that they fit between the flanges on the first and second flanged closure portions;
each of said longitudinal sides having a first end and a second end, and transverse sections extending between said first ends and said second ends;
at least one insert receiving member in at least one of said transverse sections and having a bore extending therethrough;
first and second insert members for insertion into said bore of said one insert receiving member in abutting relationship;
each of said first and second insert members having a longitudinal bore extending therethrough for containing a cable; and
holding means within said bore of said insert receiving member for holding in place said first and second insert members in butting end-to-end relationship.

Abstract
A racetrack grommet of resilient material for use in providing a seal between two flanged closure members has first and second spaced sides thereon adapted to be positioned between the flanges, and transverse end sections having insert receiving members having bores therein. Insert members are configured to fit within the bores in end to end butting relationship to provide a seal between a cable entering or leaving the assembled closure and the insert receiving members which, in turn, provide seals for end openings in the assembled closure. The bores in the insert receiving members have holding and sealing means therein and each insert has mating means thereon for mating with the holding means to provide a seal between each of the insert members and the insert receiving member. One or more port plugs seal the unused bores in the insert receiving members. Each insert has a split thereon to facilitate insertion of a cable within the insert, and each insert receiving member has a split therein for facilitating insertion of an insert therein.

15. A racetrack grommet for providing a seal between first and second flanged closure portions wherein the closure portions define first and second spaced openings in one end thereof and third and fourth openings in the other end thereof and an end compartment adjacent each opening which, when the portions are assembled, allow ingress and egress of cables, said racetrack grommet comprising:
-
a substantially rectangularly shaped member having first and second longitudinal sides spaced apart a distance such that they fit between the flanges of the first and second flanged closure portions; each of said longitudinal sides having a first end and a second end; a first transverse section extending between said first ends and a second transverse section extending between said second ends; first and second laterally spaced insert receiving members in said first transverse section and third and fourth laterally spaced insert receiving members in said second transverse section; each of said insert receiving members having an axial bore extending therethrough; first and second insert members each having a longitudinal bore extending therethrough for containing a cable; holding means within said bore of each of said insert receiving members for holding in place said first and second insert members in butting end-to-end relationship within said axial bore of each of said insert receiving members; and mating means on each of said insert members for cooperating with said holding means to retain said first and second insert members in place, said mating means and said holding means creating a substantially moisture proof seal between said insert receiving member and said inserts. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 30, 31)
