Cable seals and methods of assembly
View Patent ↗A cable seal includes a heat-shrinkable tubing coupled to a cable outer jacket. An elastic member is positioned about the heat-shrinkable tubing. A cap is positioned about the heat-shrinkable tubing. At least one of the elastic member and the cap has a vertical sealing surface and a horizontal sealing surface. The vertical sealing surface extends substantially coaxially with respect to a longitudinal axis of the cable seal, and the horizontal sealing surface extends substantially radially with respect to the cable seal longitudinal axis.
1. A cable seal comprising:
a heat-shrinkable tubing coupled to a cable outer jacket;
an elastic member positioned circumferentially about said heat-shrinkable tubing; and
a cap positioned circumferentially about said heat-shrinkable tubing such that at least a portion of said heat-shrinkable tubing extends through an open passage defined in said cap, wherein at least one of said elastic member and said cap has a vertical sealing surface extending substantially coaxially with respect to a longitudinal axis of said cable seal and a horizontal sealing surface extending substantially radially with respect to said cable seal longitudinal axis.
2. A cable seal in accordance with claim 1 , wherein said heat-shrinkable tubing is chemically bonded to said cable outer jacket.
3. A cable seal in accordance with claim 1 wherein said heat-shrinkable tubing comprises an outer layer having an outer surface that facilitates mitigating surface irregularities on said outer surface.
4. A cable seal in accordance with claim 1 , wherein said vertical sealing surface is compressed against a cable penetration.
5. A cable seal in accordance with claim 1 , wherein said horizontal sealing surface is compressed against a cable penetration.
6. A cable seal in accordance with claim 1 wherein at least one of said vertical sealing surface and said horizontal sealing surface defines said open passage sized to receive a cable therein.
7. A cable seal in accordance with claim 1 wherein said elastic member comprises a plurality of O-rings.
8. A cable penetration sealing system, said system comprising:
a cable comprising an outer jacket;
a cable seal comprising a heat-shrinkable tubing coupled to said outer jacket, an elastic member positioned circumferentially about said heat-shrinkable tubing, and a cap positioned circumferentially about said heat-shrinkable tubing such that at least a portion of said heat-shrinkable tubing extends through an open passage defined in said cap, wherein at least one of said elastic member and said cap has a vertical sealing surface extending substantially coaxially with respect to a longitudinal axis of said cable seal and a horizontal sealing surface extending substantially radially with respect to the cable seal longitudinal axis; and
a cable penetration having a surface sized to receive said cable seal therein.
9. A cable penetration sealing system in accordance with claim 8 , wherein said heat-shrinkable tubing is chemically bonded to said cable outer jacket.
10. A cable penetration sealing system in accordance with claim 8 wherein said heat-shrinkable tubing comprises an outer layer having an outer surface that facilitates mitigating surface irregularities on said outer surface.
11. A cable penetration sealing system in accordance with claim 8 , wherein said vertical sealing surface is compressed against the surface of said cable penetration.
12. A cable penetration sealing system in accordance with claim 8 , wherein said horizontal sealing surface is compressed against the surface of said cable penetration.
13. A cable penetration sealing system in accordance with claim 8 wherein at least one of said vertical sealing surface and said horizontal sealing surface defines said open passage sized to receive said cable therein.
14. A cable penetration sealing system in accordance with claim 8 wherein said elastic member comprises a plurality of O-rings.
