Abstract
A cable junction has a longitudinally subdivided housing having two connected shell sections which together surround an interior splicing chamber. A pair of shell inserts of fluid-impermeable material is accommodated in the housing about the splicing chamber and they have respective outwardly projecting juxtaposed marginal flanges which are jointly formed with a longitudinal channel bounded at its opposite lateral sides by respective juxtaposed surface portions of the flanges. A strand of sealing material is accommodated in compressed state in this channel.
Claims14
A sealed cable junction sealing a splice connection between cables, comprising a longitudinally subdivided housing having two connected shell sections which together surround an interior splicing chamber wherein spliced-together cable end portions are located;
- a pair of shell inserts of fluid-impermeable material accommodated in said housing and having respective outwardly projecting juxtaposed marginal flanges which are jointly formed with a longitudinal channel bounded at its opposite lateral sides by respective juxtaposed surface portions of said flanges;
- a strand of sealing material accommodated in compressed state in said channel;
- and at least one auxiliary passage formed in said juxtaposed surface portions and adapted to accommodate sealing material that might be squeezed out of said channel.
A sealed cable junction sealing a splice connection between cables, comprising a longitudinally subdivided housing having two connected shell sections which together surround an interior splicing chamber wherein spliced-together cable end portions are located;
- a pair of shell inserts of fluid-impermeable material accommodated in said housing and having respective outwardly projecting juxtaposed marginal flanges which are jointly formed with a longitudinal channel bounded at its opposite lateral sides by respective juxtaposed surface portions of said flanges, said juxtaposed mated flanges having a composite cross-section resembling a T, the cross-bar of which is received in respective juxtaposed grooves formed in said shell sections and the upright bar of which is provided with said surface portions.
A sealed cable junction sealing a splice connection between cables, comprising a longitudinally subdivided housing having openings through which the cables extend and two connected shell sections which together surround an interior splicing chamber wherein the spliced-together cable end portions are located, said shell sections having smooth surface portions;
- a pair of shell inserts of fluid-impermeable material accommodated in said housing and having respective outwardly projecting juxtaposed marginal flanges which are jointly formed with a longitudinal channel bounded at its opposite lateral sides by respective juxtaposed surface portions of said flanges, said shell inserts being formed with radially projecting ribs in the region of said respective openings, and facing said smooth surface portions of said shell sections in said regions;
- and a strand of sealing material accommodated in compressed state in said channel.
A sealed cable junction sealing a splice connection between cables, comprising a longitudinally subdivided housing having openings through which said cables extend and having two connected shell sections which together surround an interior splicing chamber wherein the spliced-together cable end portions are located;
- a pair of shell inserts of fluid-impermeable material accommodated in said housing and having respective outwardly projecting juxtaposed marginal flanges which are jointly formed with a longitudinal channel bounded at its opposite lateral sides by respective juxtaposed surface portions of said flanges, said surface portions defining a labyrinthine path with said surrounding shell sections;
- a strand of sealing material accommodated in compressed state in said channel and also at least partially filling said labyrinthine path formed between said shell sections and said inserts, so as to establish a circumferentially complete seal;
- radial washers of synthetic plastic material at each of said openings, at least one of said washers being of noncircular configuration, said shell sections being provided at each of said openings with a surrounding groove which accomodates said one washer in mating relationship;
- and further comprising a mechanical stress-relief device at each of said openings cooperating with a respective one of said cables, each of said devices comprising an annular holding ring disposed outwardly of but adjacent to said washers at a respective opening and provided with radially deflectable tongues engaging the surrounded cable.
