  • Publication number: 20120261156
    Abstract: The present invention is directed to a low profile protection device for protecting a cable connection. The protection device includes an elastomeric base layer, a gel sealant material coated on the elastomeric base layer; and a closure mechanism disposed along the protection device such that the protection device exerts a compressive force around the cable connection when disposed in its assembled state. The elastomeric base layer has a first longitudinal edge and a second longitudinal edge, wherein the first and second longitudinal edges are substantially parallel in an assembled state and wherein a portion of the first longitudinal edge is obliquely oriented to a portion of the second longitudinal edge in an unassembled state.

  • Patent number: 7442884
    Abstract: A seal includes a body having an exterior surface configured for sealing engagement with an entry port of an enclosure. A plurality of passages extend from a first end of the body to a second end of the body. Each of the plurality of passages is configured to receive at least one component therein. A body slit extends from the first end to the second end, and passes through the body from the exterior surface to an interior point in the body. A plurality of passage slits extend from the first end to the second end. Each of the plurality of passage slits pass through the body from the interior point in the body to a corresponding one of the plurality of passages.

  • Publication number: 20070261880
    Abstract: A telecommunications enclosure for housing lines of a telecommunications cable. The telecommunications cable includes a sheath surrounding the telecommunications lines. The enclosure includes a housing for retaining telecommunication lines therein, the housing including at least one inlet/outlet port to receive a telecommunications cable. The enclosure further includes a cable gripping device disposed in the housing. The cable gripping device includes a cable clamp and a high friction gripping surface. In one aspect, the high friction gripping surface includes a flexible abrasive material that surrounds a substantial portion of a perimeter of the telecommunications cable and is disposed between the cable sheath and the cable clamp. In other aspects, the high friction gripping surface comprises an integrally formed roughened inner band surface portion that includes a plurality of sharp protrusions. The cable gripping device can secure the cable against a pulling force of at least 100 lbs.

  • Patent number: 7186929
    Abstract: A sealing member includes an elastomeric interior portion and a rigid exterior portion. At least one passage extends through the elastomeric interior portion from a first end to a second end of the sealing member. The passage is configured to receive at least one longitudinal member therein. The elastomeric interior portion is configured for sealing engagement with the longitudinal member extending therethrough, and the rigid exterior portion is configured for sealing engagement with an entry port of an enclosure.

  • Patent number: 4857672
    Abstract: A cable closure end cap arrangement is provided, to achieve a sealing between a cable splice closure, and a cable end in communication therewith. The arrangements according to the invention may be adapted to accommodate more than one cable extending into an end of a cable closure. Preferred arrangements comprise a composite of inner and outer members, each having a bore therein. Each bore is preferably defined by an arrangement of concentric rings, or a circular ridge/trough arrangement. The circular rings include transverse walls extending therebetween, in a preferred manner permitting an accordion-like flexibility. The accordion-like rings accommodate; cables of different sizes; cables at various angles relative to the end cap arrangement and the cable closure; and, movement of the cable closure, for example upon an aerial messenger wire. End cap arrangements according to the present invention are mounted by means of a slit in communication with each bore.

  • Patent number: 4805979
    Abstract: A fiber optic splice closure for protecting the splice made into a transmission cable, containing a plurality of fibers which are to remain unsevered, comprises a base to which the cable is anchored and in which slack fibers in the uncut cable are looped and stored free of transverse barriers. The seal is made with the cables and the base by a mating cover provided with a second area to receive splice trays and slack fibers selected from the cable for splicing.
