Along with making rapid progress of network technical development, the application of network is also constantly upgraded, thus constantly proposes higher requirement to the bandwidth of wiring system.Systems provider and final user use optical fiber place-and-route product more and more when planning and planned network wiring system.Optical fiber place-and-route product no longer limitation be applied to trunk wiring system, also progress into the application such as fiber to the home (FTTH), fiber to the desk (FTTD).At the introducing wire jumper of user of access network end mainly with being prefabricated into end butterfly leading in cable, and be prefabricated into that end butterfly leading in cable is conventional is single core, its scope of application has certain limitation.
Existing optical cable deconcentrator structure is relatively complicated, and in production run, quality is difficult to obtain guarantee, and when assembling, need to wait glue to solidify completely after separated time and just can enter subsequent processing, speed of production is also greatly affected.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of structure is simple, production efficiency is high, good mechanical property and wiring little and that cost the is low multicore that takes up room is prefabricated into end butterfly leading in cable.
The purpose of this utility model is achieved through the following technical solutions: multicore is prefabricated into end butterfly leading in cable, it comprises dividing box, tail cover and cable, the tail end face of described dividing box is provided with outward extending run-out(of thread), the sidewall of run-out(of thread) is provided with external thread, the inner portion of dividing box is provided with filling slot, branched cable hole is provided with in filling slot, described branched cable hole is arranged along the length direction of dividing box, dividing box and run-out(of thread) inside also offer optical cable draw-in groove, optical cable draw-in groove starts from the end face of run-out(of thread), and terminate in filling slot, the cooperation of tail cover is arranged on run-out(of thread), described cable comprises cable skin and cable core, described cable skin is fixed between the inwall that the outer wall of run-out(of thread) and tail overlap, the part of described cable core near run-out(of thread) side is fastened in optical cable draw-in groove, cable core partially passes through branched cable hole away from run-out(of thread) side, and stretch out outside dividing box.
Described dividing box comprises upper cover and lower cover, described upper cover and under cover and be respectively arranged with buckle, upper cover and lower cover are fastened into one by buckle.
Described tail cover comprises cylindrical section and contraction section, one end of cylindrical section is connected with the large end of contraction section, the inwall of cylindrical section is provided with internal thread, and cylindrical section is connected by threaded engagement with run-out(of thread), and described cable skin convergent section is pressed on the outer wall of run-out(of thread).
The utility model has the following advantages:
1, the utility model structure is simple, easy and simple to handle, and separated time is complete can not be waited glue to solidify completely just can to flow directly to subsequent processing, greatly enhance productivity, this deconcentrator afterbody adopts spiral latch mechanism, effectively ensure that the resistance to tension of deconcentrator, ensure that product mechanical property.
2, during wiring, in the engineering of intensive wiring, single replacement many is prefabricated into end butterfly leading in cable and uses, practical, saves wiring space and engineering cost.
