Abstract
Abstract A pressure-balanced electrical assembly for a grease-filled nonhosing cable comprising: an elongated generally tubular housing; one end of the housing being adapted to sealably receive the cable; the other end of the housing being sealed and having a feed-through terminal extending therethrough for connection to the end of a cable lead; an intermediate portion of the housing being fluid-sealed and pressure-exposed to the ambient environment, said intermediate portion being capable of receiving said lead therethrough for connection to the feed-through terminal; and an opening into the intermediate portion of the housing for pressure filling said portion with a semiliquid.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A pressure-balanced electrical connector assembly for a cable of the type having at least one electrical wire in a flexible jacket filled with a liquid, comprising: a generally tubular housing; one end of the housing being adapted to sealably receive the cable; the other end of the housing being sealed and having a feedthrough terminal connector extending therethrough for connection to the end of a cable wire; an intermediate portion of the housing being capable of receiving said wire therethrough for connection to the terminal connector; the intermediate housing portion having at least one aperture; and a flexible boot sealably mounted about the intermediate housing portion and its aperture so as to fluid-seal and pressureexpose the intermediate housing portion to the ambient environment.
Claim 2
Dependent Claim
123 words
A pressure-balanced electrical connector assembly for a cable of the type having at least one electrical wire in a flexible jacket filled with a liquid, comprising: a generally tubular housing; one end of the housing being adapted to sealably receive the cable; the other end of the housing being sealed and having a feedthrough terminal connector extending therethrough for connection to the end of a cable wire; an intermediate portion of the housing being capable of receiving said wire therethrough for connection to the terminal connector; the intermediate housing portion having at least one aperture; and a flexible boot sealably mounted about the intermediate housing portion and its aperture so as to fluid-seal and pressureexpose the intermediate housing portion to the ambient environment.
Claim 3
Dependent Claim
27 words
A connector assembly as claimed in claim 1 comprising: said intermediate portion having an opening to the ambient environment for pressure-filling the intermediate portion with a liquid.
Claim 4
Dependent Claim
48 words
A connector assembly as claimed in 1 comprising: a housing portion adjacent to the intermediate housing portion having an exterior diameter no greater than the exterior diameter of the intermediate housing portion so that the boot can be slipped from the intermediate housing portion to expose said aperture.
Claim 5
Dependent Claim
74 words
A combination as claimed in claim 1 including: said cable, the cable having a jacket which contains at least one electrical wire and a grease filling; said cable sealably extending through the receiving end of the housing; the cable jacket and grease filling terminating adjacent the intermediate housing portion so as to be capable of forming an interface with liquid in the intermediate housing portion; and said wire extending through the intermediate housing portion.
Claim 6
Dependent Claim
29 words
A connector assembly as claimed in claim 2 comprising: a grease-fitting threaded within the liquid-filling opening of the intermediate housing portion; and a vent-opening in said intermediate housing portion.
Claim 7
Dependent Claim
69 words
A connector assembly as claimed in claim 5 comprising: the receiving end of the housing having a counterbore; a male adapter and packing glands received within said counterbore; an annular insert engaging the male fitting and connected to a Kellem grip for said cable; and a capnut with a central opening threaded on the receiving end of the housing for tightening the annular insert, male adapter, and packing glands.
Claim 8
Dependent Claim
36 words
A connector assembly as claimed in claim 6 comprising: the terminal end of the housing having an opening; a plug sealably disposed within the terminal end opening; and said feed-through terminal connector extending through the plug.
Claim 9
Dependent Claim
66 words
A connector assembly as claimed in claim 7 comprising: a housing portion adjacent to the intermediate housing portion having an exterior diameter no greater than the exterior diameter of tHe intermediate housing portion so that the boot can be slipped from the intermediate housing portion to expose said aperture; and a pair of worm drive clamps sealably retaining the flexible boot about the intermediate housing portion.
Claim 10
Dependent Claim
73 words
A combination as claimed in claim 8 comprising: said cable, the cable having a jacket which contains at least one electrical wire and a grease filling; said cable sealably extending through the receiving end of the housing; The cable jacket and grease-filling terminating adjacent the intermediate housing portion so as to be capable of forming an interface with liquid in the intermediate housing portion; and said wire extending through the intermediate housing portion.
Claim 11
Dependent Claim
17 words
A combination as claimed in claim 9 comprising: said intermediate housing portion being filled with a grease.
Claim 12
Dependent Claim
26 words
A combination as claimed in claim 10 comprising: said intermediate portion having an opening to the ambient environment for pressure-filling the intermediate portion with said grease.
