SEAL ASSEMBLY/ADAPTOR FOR AN INTERFACE PORT

摘要

A seal assembly/adaptor for sealing a weather protection boot to an irregular shaped interface port such as a port having externally facing threads. The seal assembly/adaptor includes a seal subassembly comprising a compliant ring having plurality of arcuate segments defining an opening for accepting the interface port. Further, the seal assembly/adaptor includes at least one retainer operative to retain the seal subassembly such that, upon assembly, an axial force imparted by a connector coupling device effects radial deformation of at least one of the flexible segments into the irregular surface of the interface port to effect a seal between the irregular surface and the retainer.

1. A seal assembly for forming an irregular fitted seal with a threaded interface port and a sealing boot of a weather protection system, the seal assembly comprising:
a seal member including a compliant ring having a plurality of resilient thread engaging segments configured to (i) extend inwardly from the ring structure, (ii) deformably fit with at least one of the threads of the interface port, and (iii) move between an uncompressed state, where the resilient thread engaging segment defines a first inner diameter dimension sized to allow the resilient thread engaging segment to fit into the at least one of the threads of the interface port, and a compressed state, where the resilient thread engaging portion has a second inner diameter dimension which is less than the first inner diameter dimension, the seal member being deformably pressed into at least one of the threads of the interface port so as to form a fitted seal with the at least one thread of the interface port and to prevent contaminants from infiltrating through the at least one thread of the interface port, when the seal member is in an assembled state; a first seal member retaining structure configured to fit around a portion of the seal member so as to form a seal subassembly, the first seal member retaining structure including a compression structure configured to cause the seal member to move from the uncompressed state to the compressed state, and a second seal member retaining structure including a coupling portion configured to be coupled to the threads of the interface port when the seal assembly is in the assembled state, and a resilient shoulder configured to extend inwardly and radially displaced between a closed position, where the resilient shoulder defines a first inner shoulder diameter dimension that is less than an outer diameter dimension of the seal subassembly, and an open position, where the resilient shoulder defines a second inner shoulder diameter dimension that is greater than the first inner shoulder diameter dimension and is greater than the outer diameter dimension of the seal subassembly so as to allow the seal subassembly to fit within a portion of the second seal member retaining structure.
