Adapter for sealing boot for electrical interconnections
An adapter for a sealing boot includes: an annular body having a radially-outward exterior surface; at least one helical thread extending radially inwardly to define a threaded interior surface and defining a plurality of roots and crests, wherein the crests extend radially inwardly a distance A from the roots; and a blocking section that extends axially across the plurality of roots and crests, the blocking section extending radially inwardly at least the distance A from the roots at junctions with the crests, and extending radially inwardly a distance B from the roots in areas between the roots and crests.
1. An adapter for a sealing boot, comprising:
an annular body having a radially-outward exterior surface;
at least one helical thread extending radially inwardly to define a threaded interior surface and defining a plurality of roots and crests,
wherein the crests extend radially inwardly a distance A from the roots;
and a blocking section that extends axially across the plurality of roots and crests,
the blocking section extending radially inwardly at least the distance A from the roots at junctions with the crests,
and extending radially inwardly a distance B from the roots in areas between the roots and crests,
wherein the distance A is the same as the distance B,
wherein the blocking section is a first blocking section,
and further comprising a second blocking section that extends axially across the plurality of roots and crests,
the second blocking section extending radially inwardly at least the distance A from the roots at junctions with the crests,
and extending radially inwardly a distance B from the roots in areas between the roots and crests,
the second blocking section being circumferentially separated from the first blocking section,
in combination with a bulkhead connector having a threaded stem, the adapter being threaded onto an external thread of the threaded stem to form a seal between the adapter and the threaded stem.
2. The adapter defined in claim 1 , comprising a resilient material.
3. The adapter defined in claim 2 , wherein the resilient material is selected from the group consisting of: silicone rubber, EPDM and neoprene rubber.
4. The adapter defined in claim 1 , in combination with a sealing boot having a sealing neck, wherein the sealing neck encircles and seals against the exterior surface of the adapter.
5. An assembly, comprising:
(a) a threaded stem having an external helical thread;
(b) a sealing adapter comprising an annular body having:
a radially-outward exterior surface;
at least one helical thread extending radially inwardly to define a threaded interior surface and defining a plurality of roots and crests,
wherein the crests extend radially inwardly a distance A from the roots;
and a blocking section that extends axially across the plurality of roots and crests,
the blocking section extending radially inwardly at least the distance A from the roots at junctions with the crests,
and extending radially inwardly a distance B from the roots in areas between the roots and crests;
wherein the distance A is the same as the distance B;
and (c) a sealing boot having a sealing neck; wherein the sealing neck encircles and seals against the exterior surface of the sealing adapter;
and wherein the sealing adapter is threaded onto the thread of the threaded stem such that the blocking section forms a seal between the adapter and the threaded stem;
wherein the blocking section is a first blocking section,
and further comprising a second blocking section that extends axially across the plurality of roots and crests,
the second blocking section extending radially inwardly at least the distance A from the roots at junctions with the crests,
and extending radially inwardly a distance B from the roots in areas between the roots and crests,
the second blocking section being circumferentially separated from the first blocking section,
in combination with a bulkhead connector having a threaded stem, the adapter being threaded onto an external thread of the threaded stem to form a seal between the adapter and the threaded stem.
6. The adapter defined in claim 5 , comprising a resilient material.
7. The adapter defined in claim 6 , wherein the resilient material is selected from the group consisting of: silicone rubber, EPDM and neoprene rubber.
