  • Protection of cable splice
    Patent number: 4686327
    Abstract: A splice between two multiconductor cables is protected from ingress of water by a closure which contains a pressure means such as a bladder inside the closure capable of pressurizing a sealant present inside the closure to a pressure sufficient to force the sealant into the interstices of the splice and the interstices between the conductors in the cable, and maintaining the pressure until the sealant cures or hardens. The pressure means may also interact with seals at the end of the closure to seal the closure to the cable jacket.
