Abstract
The utility model relates to an indoor micro-armored flexible optical cable consisting of an optical fiber (1), a micro-armor (2), aramid (3), a stainless steel wire braided fabric (4) and a sheath (5). The indoor micro-armor flexible optical cable is characterized in that the outer diameter of the optical fiber (1) is smaller so that bending property is enhanced; side pressure resistance of the optical cable is strengthened to be 3000N through the micro-armor (2) coated outside the optical fiber (1) so that the optical fiber is protected against collision of external force; the micro-armor (2) is covered with the aramid (3), the aramid (3) is covered with a layer of the stainless steel wire braided fabric (4), and tensile strength of the optical cable is increased to be 1200N by the aramid (3) and the stainless steel wire braided fabric (4); and the sheath (5) which is a polyurethane sheath is arranged on the outermost layer and has wear resistance, so that the compression resistance and the tension resistance of the optical cable are improved, the optical cable is not easy to be broken, the optical fiber is not easy to be damaged by metal armored on the optical cable, and the optical cable can be used in severe environments.
Description
Technical field
The utility model relates to a kind of indoor flexible optical cable, the indoor flexible optical cable of particularly a kind of miniature armouring.
Background technology
The indoor flexible optical cable that just present domestic production producer is produced do not have the metal armouring layer, and anti-pressure ability is bad, and is poor because of the bending property of ordinary optical cable again, is easy to fracture, so just must pass through to increase the bending of the diameter of optical cable with the opposing optical cable.The general room flexible optical cable collides with then as being subjected to external force that optical fiber is easy to fracture, and the armouring metal hurts optical fiber again easily on the optical cable, because total is not tight, quite a few concentrates on the sheath to bear tension force, and the performance that strengthens the element effect is very limited.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, the indoor flexible optical cable of a kind of miniature armouring is proposed, form by optical fiber (1), miniature armouring (2), aramid fiber (3), stainless steel wire braid (4), oversheath (5), it is characterized in that optical fiber (1) external diameter is littler, optical fiber (1) outer wrapping miniature armouring (2), miniature armouring (2) is outer to be surrounded by aramid fiber (3), aramid fiber (3) is outer to be wrapped up by one deck stainless steel wire braid (4), outermost layer is oversheath (5), and oversheath (5) is wrapped in stainless steel wire braid (4) outside.
The beneficial effects of the utility model are: littler by the optical fiber external diameter, the wrapped miniature armouring of stainless steel band improves the lateral pressure resistant ability of optical cable, makes its lateral pressure resistant ability reach 3000N; Aramid fiber and stainless steel wire braid improve the tensile strength of optical cable, the tensile strength that guarantees optical cable reaches 1200N, sheath adopts polyurethane jacket, make optical cable have wear-resisting performance, to improve resistance to compression, resistance to tension, make optical cable be not easy to fracture, the armouring metal on the optical cable is not easy to hurt optical fiber, can use in rugged environment.

Fig. 1 is the utility model front view.
Embodiment
According to shown in Figure 1, the indoor flexible optical cable of the miniature armouring of the utility model, the external diameter of optical fiber (1) is littler, optical fiber (1) outer wrapping miniature armouring (2), miniature armouring (2) is outer to be surrounded by aramid fiber (3), aramid fiber (3) is outer to be one deck stainless steel wire braid (4), and outermost layer is to adopt polyurethane oversheath (5).
Claims (1)
1. indoor flexible optical cable of miniature armouring, form by optical fiber (1), miniature armouring (2), aramid fiber (3), stainless steel wire braid (4), oversheath (5), it is characterized in that optical fiber (1) external diameter is littler, optical fiber (1) outer wrapping the wrapped miniature armouring of stainless steel band (2), miniature armouring (2) is outer to be wrapped up by aramid fiber (3), aramid fiber (3) is outer, and outermost layer is oversheath (5) by one deck stainless steel wire braid (4) parcel, and oversheath (5) is wrapped in stainless steel wire braid (4) outside.
