Abstract
A sealed fiber optic enclosure assembly includes a fiber optic enclosure having an inner rim, and an end cap shaped to fit the enclosure. The end cap has a pliable membrane depending from it. The membrane is approximately a cylindrical structure. The membrane may have a wedge-shaped cross section. The wedge-shaped cross section may have an elbow in it. The membrane and end cap may be formed from a single piece of a pliable material, such as polypropylene. The membrane extends into the rim of the enclosure when the end cap is in place on the enclosure. The enclosure has a neck that transitions from a first diameter to a second diameter smaller than the first diameter. The second diameter is smaller than a diameter of the membrane. A clamp is placed over mating portions of the enclosure and end cap, for clamping the end cap to the enclosure. The clamp may be a V-clamp. Pressure is introduced to the enclosure. The membrane is forced against the rim when the enclosure is pressurized, to form a seal between the membrane and the rim. A gap is present between the membrane and a neck portion of the rim before the enclosure is pressurized. The membrane moves to bridge the gap when the enclo…
