Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figures 1 to 4, the hermetically-sealed construction of the optoelectronic composite cable joint in the present embodiment includes splitter, at the inner cavity 10a that forms both ends open and supply optoelectronic composite cable 1 branch and continue of splitter, splitter comprises splitter main casing 10 and is threaded in respectively the first housing 7 and second housing 12 at splitter main casing two ends, in the threaded connection place of splitter main casing 10 and the first housing 7, be provided with the first sealing ring 9, in the threaded connection place of splitter main casing 10 and the second housing 12, be provided with the second sealing ring 11, for improving the sealing being threaded, can also on the screw thread of above-mentioned threaded connection place, be coated with silica gel, like this, the first housing 7 and the second housing 12 are just all sealedly connected on splitter main casing 10.In addition, in the present embodiment, the first sealing ring 9 and the second sealing ring 11 are rubber seal.
The first housing 7 passes for optoelectronic composite cable 1 inputs, in the inside of the first housing 7 and the surface of optoelectronic composite cable 1 input be coated with silica gel, thereby between the first housing 7 and optoelectronic composite cable 1 input, form the first hermetically-sealed construction.In gap 72 between the first housing 7 and optoelectronic composite cable 1 oversheath, fill up the outer water blocking tape layer that optoelectronic composite cable 1 carries, outer waterstop is filled up after above-mentioned gap 72 is interior, can strengthen block-water performance, thereby further improve the sealing between the first housing 7 and optoelectronic composite cable 1 input.In addition, have the radially screw 73 being oppositely arranged on the first housing 7, screw 8 is screwed in corresponding radially screw 73 and the first housing 7 is fixed on optoelectronic composite cable 1 input.
The second housing 12 passes for optoelectronic composite cable 1 outputs, and optoelectronic composite cable 1 forms two optical cable subelement 1b and a separate cable 5 in the cavity 10aNei Jing of splitter branch, after continuing.On the optoelectronic composite cable that is positioned at splitter main casing 10, be wound with the water blocking tape layer that optoelectronic composite cable carries, water blocking tape layer is filled up in the cavity 10a of splitter main casing, if desired, can also increase again fixedly water blocking tape layer of electrical adhesive tape, adopt after waterstop winding arrangement, when strengthening inner active block-water performance, can also reduce follow-up colloid use amount.During actual production, can be first poor toward the interior injection mobile performance of splitter main casing 10 when being unkitted the second housing 12, the neutral density glass glue bottoming (not shown) of easily repairing, on splitter main casing 10, load onto again the second housing 12 and pour into the epoxy resin glue that mobile performance is stronger, so not only can reduce the use amount of epoxy resin glue, filling time is very fast, and can also avoid the waterstop of optoelectronic composite cable directly to contact epoxy resin glue, after epoxy resin glue is frozen into body 13, optical cable subelement 1b and separate cable 5 and the second housing 12 fix and form effective the second hermetically-sealed construction.And the second sealing ring 11 of being located at the threaded connection place of splitter main casing 10 and the second housing 12 can prevent that epoxy resin glue from overflowing when encapsulating.
The cable subelement of optoelectronic composite cable input and the cable subelement of optoelectronic composite cable output continue in cavity, for improving optoelectronic composite cable in the sealing at place that continues, at the cable subelement continuing, be crimped with copper gland pipe 31 outward, at copper gland pipe 31 overcoats, there is the first band glue heat-shrinkable T bush 3, and this is adsorbed on glue heat-shrinkable T bush 3 pyrocondensations simultaneously on the insulating sleeve of the cable subelement continuing and forms insulating protective layer, to play the fixing and sealed insulation effect of strengthening.In addition, for further improving sealing, in the present embodiment, on splitter main casing 10, be arranged with the second band glue heat-shrinkable T bush 2, and second the input to optoelectronic composite cable extends and is set in the first housing 7 and exposes on the optoelectronic composite cable 1 of splitter with glue heat-shrinkable T bush 2 for this, on the output of optoelectronic composite cable that exposes to splitter, be arranged with the 3rd band glue heat-shrinkable T bush 4.
In addition, in order to be provided with the lining 6 of an energy banding optoelectronic composite cable input in the armour 1a that closely connects optoelectronic composite cable and the first housing 7, the first housings 7.Particularly, this lining 6 is eight pawl structures, in the first housing 7 inside, is formed with step surface 71, and the surface, claw outer ring of lining 6 is subject to the extruding of step surface 71 to be out of shape and to tighten up and the armour 1a of banding optoelectronic composite cable input afterwards.During production, optoelectronic composite cable oversheath stays one section of armour 1a when stripping, and armour surface removal coating layer is to increase conducting area, and lining 6 is enclosed within outside armour 1a, and is pressed into the first housing 7.
The foregoing is only preferred implementation of the present utility model; it should be pointed out that for those of ordinary skills, do not departing under principle prerequisite of the present utility model; can carry out multiple remodeling or improvement to the utility model, within these are all regarded as protection range of the present utility model.
