초록 ▼

A device to form an effective environmental tight seal on a free end of cables, conduits and the like is disclosed. The subject device is formed by a unitary member of resilient material, such as rubber, which has a cylindrical configuration with one permanently closed end. The closed end has a substantially greater thickness than the sidewalls of the device. The other end is preferably temporarily closed. The device is applied by forcing the permanently closed end against the free end of the cable so that the closed end passes through the cylindrical portion until the device is reversed upon itself and is in sealing gripping engagement on the cable or the like. When one end of the device is temporarily closed by a sealing member, the device will be slightly inflated as it is pushed against the cable end thereby easing application of the device. The temporary seal will be removed by penetration or when internal pressure increases beyond a limit.

대표청구항 ▼

A sealing device for effecting an environmental tight seal on a free end of a cable, conduit, or the like, said sealing device comprising: a hollow unitary member of flexible resilient material including a cylindrical body, a conically outwardly flared portion extending from one end of said cylindrical body, an end wall closing the larger end of said conically flared portion, said end wall having a substantially greater thickness than the sidewalls of said body, and a plurality of aNnular bands spaced along the outer surface of said cylindrical body, means temporarily closing the other end of said hollow unitary member whereby pressing of the end wall against an end of a cable, conduit, or the like causes limited inflation of said hollow unitary member thereby easing passage of said end wall through said hollow unitary member until it sealingly engages such end in an inside-out condition, said temporary closure means being removed by said through passage. A sealing device for effecting an environmental tight seal on a free end of a member, such as a cable, conduit, or the like, said device comprising: a hollow cylindrical member of inflatable material capable of withstanding low internal pressures, and having a permanently sealed first end, a frangible seal temporarily sealing a second end, and pointed means fixed to said permanently sealed first end which, when brought into contact with the second end of said device, causes the frangible seal to be ruptured thereby allowing passage therethrough of said first end, said device being reversible upon itself during application by pressing said first end against said free end and driving said first end through said hollow cylindrical member.
