Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the single-ended mechanical seal cable splice closure of the utility model.
See accompanying drawing 1,2,5,6, single-ended mechanical seal cable splice closure comprises cylindrical shell 1, the cylindrical shape of cylindrical shell, its one end is blind end, and the other end is tip side, tip side opening, for erection joint end cap 2, end cap is arranged on tip side by mechanical sealing sealing structure.Described cylindrical shell arranges anchor ear 3, for being fixedly mounted by connector box.Connector box also can be provided with ground extractor.
See accompanying drawing 2,3, end cap 2 is in the form of annular discs, end cap has six optical cables and import and export 4, six optical cables are imported and exported 4 and are uniformly arranged on a circumference, this circumference and end cap 2 are concentric circles, the inner side of end cap is fixedly installed web joint 5, described web joint is installed storage disks 6, described storage disks 6 installs six fusion joining disks 7, described web joint 5 and welding plate 7 are contained within described cylindrical shell 1, described storage disks 6 is provided with nylon cable tie, and described nylon cable tie is for being fixed on described storage disks by described fusion joining disk.
See accompanying drawing 3,4, described optical cable installs elastomer sealing ring on importing and exporting respectively, the centre of described O-ring seal is provided with through hole, described optical cable arranges external thread on importing and exporting, described external thread is used for coordinating with a nut 8, opens hole in the middle of described nut 8, described O-ring seal is set in a nut, together with described nut 8 and described optical cable are imported and exported and be screwed in.Plug 9 is set in described through hole.Described plug is large, medium and small three mutual embedding plugs.The color of plug can be set to multiple, for the examination after optical cable access.Between two in described six optical cables are imported and exported, offer a groove 10, described groove makes described two optical cables import and export formation waist hole, and described waist hole is used for straight-through optical cable turnover.
See accompanying drawing 7, respectively bifurcation optical cable and straight-through optical cable access connector box seal operation step are described below.
Bifurcation optical cable access procedure is as follows, the optical cable that stripping is good is ready to, and opens connector box, is taken away by the plug intending penetrating optical cable, open nut and nut is penetrated optical cable, range estimation optic cable diameter also judges the optical cable O-ring seal matched, or is directly penetrated by the optical cable that stripping is good, if O-ring seal is meticulous, then take away the small size O-ring seal of innermost layer, if still can not penetrate, then the medium size O-ring seal of centre is taken away not, to be slightly tightly advisable when optical cable penetrates.After optical cable welding, be fixed on after in fusion joining disk, tightening nuts; After nut is tightened, colored elastomer sealing ring can stretch out outside nut, so that the acceptance of work.
Straight-through optical cable access procedure is as follows, straight-through optical cable according to the needs installed, cable sheath is peeled off, reserves straight-through Loose tube, cut off the Loose tube needing difference, according to the length that strengthening core is fixing, cuts off middle unnecessary optical cable strengthening core.The half nut of straight-through optical cable inlet/outlet pipe is twisted off, and takes out split washer, clear opening O-ring seal and plug successively.Take away plug, according to the diameter installing straight-through optical cable, select suitable clear opening O-ring seal to install.If what install is middle diameter optical cable, minor diameter O-ring seal can be removed, in clear opening O-ring seal cutter vertically cut from side, then optical cable loose tube to be snapped in from incision, then snap in split washer, half nut successively, and with screw, half nut is fixed; Then Loose tube is curved U-shaped, penetrates from straight pipe opening part, put clear opening O-ring seal, then put clear opening O-ring seal pressing plate, and be screwed firm.Fix optical cable and strengthening core thereof, finally split washer is put into optical cable inlet/outlet pipe, tightening nuts can ensure sealing.If do not need to install straight-through optical cable, clear opening also can use as difference hole.When using as difference hole, without the need to nut, plastic washer, elastomer sealing ring are split or cut, also without the need to opening clear opening pressing plate, can be direct as difference hole.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
