Environmentally sealed wrap-around sleeves having a longitudinal sealant chamber
First Claim
1. A wrap-around cable sleeve for environmentally sealing a cable section, said wrap-around cable sleeve comprising:
- a wrap-around body member comprising an electrically insulating material and having a longitudinally extending portion with a corrugated lateral cross-section, the longitudinally extending portion defining a portion of a cable chamber extending at least substantially around the cable section when the body member is wrapped around the cable section;
a closure edge extending along a first longitudinal edge of the body member;
a sealant chamber extending along a second longitudinal edge of the body member and having an opening configured to receive the closure edge when the body member is wrapped around the cable section;
a sealant material positioned in the sealant chamber to environmentally seal the longitudinal edges of the body member when the body member is wrapped around the cable section; and
a first sealant material layer on an inner face of the body member at a first end thereof and extending transversely substantially across the first end of body member to define a continuous environmental seal between the cable section and the first end of the body member when the body member is wrapped around the cable section, wherein the first sealant material layer and the sealant material positioned in the sealant chamber sealingly contact each other when the body member is wrapped around the cable section.

Abstract
Wrap-around cable sleeves are provided for environmentally sealing a cable section. The cable sleeves include a wrap-around body member of an electrically insulating material and have a longitudinally extending portion with a corrugated lateral cross-section. The longitudinally extending portion defines a portion of a cable chamber extending around the cable section when the body member is wrapped around the cable section. A closure edge extends along a first longitudinal edge of the body member. A sealant chamber extends along a second longitudinal edge of the body member. The sealant chamber has an opening configured to receive the closure edge when the body member is wrapped around the cable section. A sealant material is positioned in the sealant chamber to environmentally seal the longitudinal edges of the body member when the body member is wrapped around the cable section. Methods of forming wrap-around cable sleeves are also provided.
