Abstract
The utility model discloses an indoor and outdoor self-supporting armored bow-type drop optical cable. The drop optical cable comprises an optical cable unit and a self-supporting unit which are axially arranged in parallel. The optical cable unit comprises a bow-type cable arranged in the center of the optical cable unit, an armored layer cladded on the exterior of the bow-type cable, and aramid yarns cladded on the exterior of the armored layer. The self-supporting unit comprises a reinforcing piece of which the axial lead is arranged in parallel with the axial lead of the optical cable unit. A sheath layer is cladded on the exterior of the aramid yarns and the reinforcing piece. As the armored layer is cladded and lapped on the exterior of the bow-type optical cable of the drop optical cable, the drop optical cable has a good anti-mouse gnawing function; and side pressure prevention and external force impact prevention capabilities of the optical cable are improved, and relatively stronger mechanical strength is ensured; and the drop optical cable can be used for indoor and outdoor laying at the same time.
Description
Technical field
the utility model relates to communications optical cable, particularly, relates to a kind of indoor and outdoor with self-bearing type armouring butterfly leading in cable.
Background technology
existing butterfly optical cable has two kinds of GJYXCH butterfly optical cable and GJYXFCH butterfly optical cables; And these two kinds of butterfly optical cables in use have following shortcoming: 1., be used for outdoor when built on stilts; Optical cable is running into external impacts moment; Act directly on the optical fiber, cause fibercuts easily or damage is arranged; 2., the two does not have to add anti-mouse material, so after laying, does not have well anti-mouse to sting function and lateral pressure resistant power; 3., after Fiber to the home, the mouse bite preventing self-support cable need be used in the mountain area, conventional self-bearing type butterfly leading in cable can't satisfy its environment for use; China is in the initial stage that FTTX optical fiber is registered one's residence at present; Optical cable for optical fiber to house is laying at batch, but after being used for the indoor and outdoor fiber cable laying in mountain area, occurs being bitten broken optical fiber and reaching loss increase phenomenon by mouse through regular meeting; Cause line interruption, the circuit emergency repair cost is than higher.
Summary of the invention
the utility model provide a kind of mouse bite preventing is effective, lateral pressure resistant power ability is strong indoor and outdoor with self-bearing type armouring butterfly leading in cable.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
a kind of indoor and outdoor is with self-bearing type armouring butterfly leading in cable; Comprise optical cable unit that axial parallel is provided with and from bearing unit; Described optical cable unit comprise the center of being arranged on butterfly optical cable, be coated on described butterfly optical cable the outside armor and be coated on the aramid yarn of the outside of described armor; Described self-supporting unit comprises that the axial line of axial line and described optical cable unit parallels the reinforcement of setting, and the external packets of described aramid yarn and described reinforcement is covered with restrictive coating.
preferably, described reinforcement is selected the steel wire reinforcement for use.
preferably, described restrictive coating is processed for the low-smoke non-halogen flame-retardant material.
preferably, the xsect of this leading in cable is " 8 " font.
The beneficial effect of
utility model is: have good anti-mouse to sting function after the outside coating armouring of the butterfly optical cable of this leading in cable is wrapped; Simultaneously also improved anti-side pressure and external impacts ability, physical strength is better; Product can be used for outdoor and indoor laying simultaneously.
Description of drawings
accompanying drawing 1 is the horizontal cross-sectional structure synoptic diagram of the indoor and outdoor of the utility model with self-bearing type armouring butterfly leading in cable.
In
accompanying drawing: 1, butterfly optical cable; 2, armor; 3, aramid yarn; 4, reinforcement; 5, restrictive coating.
Embodiment
Below in conjunction with embodiment shown in the drawings the technical scheme of the utility model is done following detailed description the in detail:
are shown in accompanying drawing 1; The indoor and outdoor of the utility model comprises optical cable unit that axial parallel is provided with self-bearing type armouring butterfly leading in cable and from bearing unit; The optical cable unit comprise the center of being arranged on butterfly optical cable, be coated on butterfly optical cable the outside armor and be coated on the aramid yarn of the outside of armor; The self-supporting unit comprises that the axial line of axial line and optical cable unit parallels the reinforcement of setting, and the external packets of aramid yarn and reinforcement is covered with restrictive coating, and reinforcement is selected the steel wire reinforcement for use; Restrictive coating is processed for the low-smoke non-halogen flame-retardant material, and the xsect of this leading in cable is " 8 " font.
The manufacturing approach of
this leading in cable: the butterfly optical cable external packets is around the stainless steel armor at first again, and detects, and wrapped then aramid yarn and tygon steel wire oversheath detect at last equally, and technology is simple, and yield rate is high.
this optical cable can guarantee the mechanical property and the environmental resistance of optical cable; Around butterfly optical cable, increased armor and can prevent that effectively mouse stings; The peripheral one deck aramid yarn that twines of armor can increase the lateral pressure resistant power performance of optical cable and increase stretching resistance; In the process debugging process, through the laying tension of adjustment armour pipe and the lay of lapping of aramid yarn, solved problem that armor is elongated easily and the aramid yarn problem with armour pipe uniform winding, critical problem has obtained good solution; After can utilizing existing distribution plant assembling, directly put into production, need not increase equipment investment.
the foregoing description is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
Claims (4)
