Abstract
The utility model provides a butterfly covered wire optical cable head structural member comprising a butterfly covered wire optical cable, a butterfly covered wire optical cable reinforced member, a stop ring and a tail tube; the butterfly covered wire optical cable reinforced member is fixed on the stop ring; the tail tube is fixed outside the butterfly covered wire optical cable reinforced member; fibers of the butterfly covered wire optical cable penetrate a hole of the tail tube; the butterfly covered wire optical cable head structural member also comprises a metal tail tube arranged behind the stop ring. The butterfly covered wire optical cable head structural member uses the reinforced member of the butterfly covered wire optical cable, the reinforced member is fixed on the stop ring of the structural member so as to bear a pulling force between a plug and the butterfly optical cable, thereby providing pulling force and performance requested by standards.
Description
Technical field
The utility model relates to a kind of butterfly covered wire cable and adds header structure part, and especially a kind of have a stretching resistance effect, and the butterfly covered wire cable that meets master gauge provisioning request adds header structure part.
Background technology
Optical fiber access market presents in the situation of good growth momentum at home, and optical fiber access has become the focus in optical communication field.In optical fiber access engineering, near user's house wiring, be the most complicated link, the bending property of conventional inside cable, tensile property can not meet FTTH(Fiber to the home) demand of house wiring.Butterfly leading in cable for Access Network (indoor and outdoor wiring with) is in center by optical communication element (optical fiber), two parallel non-metal reinforcement members (FRP) or metal stiffener are placed in both sides, finally, extruding black or color polyvinyl chloride (PVC) or low smoke and zero halogen material guards forms.
The Cheng Duan that adds head at butterfly covered wire cable, needs to have certain pulling force between plug and butterfly optical cable.Comprise online tensile test, when pulling force need to reach 50N, Insertion Loss changing value≤0.2db; Physical connection tensile test, pulling force need to reach 60N and can not destroy existing structure.Between current existing plug and butterfly optical cable, pulling force does not reach the requirement of standard regulation, and particularly online tensile test, can not meet standard-required completely.
Utility model content
The utility model is for current butterfly covered wire cable, to add the one-tenth end above shortcomings part of head, provides a kind of butterfly covered wire cable to add header structure part, can arrive pulling force requirement.
Specifically, butterfly covered wire cable described in the utility model adds header structure part and comprises butterfly covered wire cable, butterfly covered wire cable reinforcement, stop collar, metal tail pipe and metal crimp T-Ring, described butterfly covered wire cable reinforcement is fixed on stop collar, after stop collar, be provided with metal tail pipe, after metal tail pipe, outside is provided with metal crimp T-Ring, the external stability of butterfly covered wire cable reinforcement has metal tail pipe, and the optical fiber of butterfly covered wire cable passes from the hole of described metal tail pipe.
Further, described butterfly covered wire cable adds header structure part and also comprises the metal tail pipe being arranged on after stop collar.
Further, described butterfly covered wire cable adds header structure part and also comprises and be arranged on metal crimp T-Ring outside after metal tail pipe.
Further, in described metal crimp T-Ring outside, be provided with tail cover.
Butterfly covered wire cable described in the utility model adds header structure part, has the following advantages:
1, this structural member is mainly used in butterfly covered wire cable and adds head, makes it to meet completely standard-required;
2, utilize the reinforcement (steel wire or FRP) of butterfly covered wire cable itself, " stop collar " that reinforcement is fixed on to structural member is upper, makes reinforcement bear pulling force suffered between plug and butterfly optical cable, thus the desired pulling force of the standard that reaches and performance;
3, structural member " metal tail pipe " crimping is fixed on " stop collar " of structural member, " metal tail pipe " increases the space of optical fiber micro-bending in butterfly covered wire cable, and connects " stop collar " and butterfly covered wire cable " reinforcement ";
4, in butterfly covered wire cable, optical fiber passes from the hole of " metal tail pipe ", forms and adds head with other structural members;
5, use metal tube that the reinforcement crimping of butterfly covered wire cable itself is fixed on " metal tail pipe ".
Accompanying drawing explanation
Fig. 1 is the utility model embodiment cross-sectional view;
Wherein, 1, ceramic insertion core 2, inside casing cover 3, outer frame set 4, spring 5, metal caudal peduncle 6, stop collar 7 metal tail pipes 8, metal crimp T-Ring 9, butterfly covered wire cable reinforcement 10, tail cover 11, butterfly covered wire cable.
Embodiment
Below in conjunction with accompanying drawing, described technology contents is carried out to nonrestrictive description, object is understood described technology for the public is better.
As shown in Figure 1, butterfly covered wire cable described in the utility model adds header structure part, comprise butterfly covered wire cable 11, butterfly covered wire cable reinforcement 9, stop collar 6 and metal tail pipe 7, described butterfly covered wire cable reinforcement 9 is fixed on stop collar 6, the external stability of butterfly covered wire cable reinforcement 9 has metal tail pipe 7, the optical fiber of butterfly covered wire cable 11 passes from the hole of described metal tail pipe 7, described butterfly covered wire cable adds header structure part and also comprises the metal caudal peduncle 5 being arranged on after stop collar 6, described butterfly covered wire cable adds header structure part and also comprises the outer frame set 3 that is arranged on metal caudal peduncle 5 rear outsides, in outer frame set 3, be provided with inside casing cover 2, between stop collar 6 and metal caudal peduncle 5, be provided with spring 4, at the rear portion of described outer frame set 3, be inserted with ceramic insertion core 1, outside at described butterfly covered wire cable reinforcement 9 is provided with metal crimp T-Ring 8, in described metal crimp T-Ring 8 outsides, be provided with tail cover 10.
Butterfly covered wire cable described in the utility model adds header structure part, utilize the reinforcement (steel wire or FRP) of butterfly covered wire cable itself, reinforcement is fixed on " stop collar " of structural member, make reinforcement bear pulling force suffered between plug and butterfly optical cable, thereby the desired pulling force of the standard that reaches and performance, mainly be used in butterfly covered wire cable and add head, make it to meet completely standard-required.
It should be understood that, foregoing does not have any restriction to described technology contents, in fact, all improvement of described structure being carried out with identical or approximate principle, comprise each several part shape, size, all materials, and the replacement of the functional equivalent of respective element, all within the desired technology contents of the utility model.
