Abstract
The utility model relates to a protection cover for a field optical cable, and the protection cover comprises an optical fiber disposed in the center of the protection cover. An inner elastomer is disposed outside the optical fiber. A layer of tight sleeve pipes is extruded outside the optical fiber. The inner elastomer is filled with aramid. An outer elastomer is disposed outside the inner elastomer and is provided longitudinally with a U-shaped groove. The protection cover for the field optical cable has the advantages of rapid construction and distribution, excellent resistance to lateral pressure and external shocks, substantially high mechanical strength and elasticity, capability of effectively protecting the cables against effects of external forces such as harsh pressure and shocks and avoiding breaking of the optical cable to ensure normal transmission of optical signals, convenient laying, simple processing technology and high yield.
Description
Technical field
The utility model proposes a kind of protective sleeve, particularly a kind of optical fiber cable for field operation protective sleeve.
Background technology
In the prior art, optical fiber cable for field operation is directly to lay to pull in the process of using, and is very easy to the sheath on optical cable surface is pulled, and can cause disconnected cable under the serious situation, causes signal constantly and can not proper communication.。
Summary of the invention
The utility model purpose is for a kind of optical fiber cable for field operation protective sleeve that can better prevent external impacts is provided.
For achieving the above object, the utility model solves the scheme that its technical matters takes and is:
This optical fiber cable for field operation protective sleeve; comprise the optical fiber that is positioned at the protective sleeve center; described optical fiber is outside equipped with interior elastic body; described optical fiber extrudes the tight sleeve pipe of one deck outward; be filled with aramid fiber in the elastic body in described; elastic body is outside equipped with outer elastic body in described, offers a U-shaped groove on described outer elastic body is vertical.
Compared with prior art, usefulness of the present utility model is: this optical fiber cable for field operation protective sleeve has rapid construction and lays, excellent lateral pressure resistant ability and external shock resistance ability, and physical strength, elasticity are very high; Can protect optical cable in the influence of external force such as abominable pressure and impact effectively, avoid optical cable to produce disconnected fine situation effectively, thereby the normal transmission that guarantees the optical cable signal be used; And lay conveniently, processing technology is simple, the yield rate height.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model optical fiber cable for field operation protective sleeve structural representation.
Among the figure: 1, optical fiber; 2, tight sleeve pipe; 3, aramid fiber; 4, interior elastic body; 5, outer elastic body.
Embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
A kind of optical fiber cable for field operation protective sleeve shown in Figure 1; comprise the optical fiber 1 that is positioned at the protective sleeve center; described optical fiber 1 is outside equipped with interior elastic body 4; the described optical fiber 1 outer tight sleeve pipe 2 of one deck that extrudes; be filled with aramid fiber 3 in the elastic body 4 in described; elastic body 4 is outside equipped with outer elastic body 5 in described, offers a U-shaped groove on described outer elastic body 5 is vertical.The optical fiber cable for field operation protective sleeve mainly is to be extruded by special particular manufacturing craft by elastomeric TPU or PU material to form, and in use, directly optical fiber cable for field operation is embedded in the cable protection cover, can protect optical fiber cable for field operation to avoid the damage of external force effectively.
This optical fiber cable for field operation protective sleeve has rapid construction and lays, excellent lateral pressure resistant ability and external shock resistance ability, and physical strength, elasticity are very high; Can protect optical cable in the influence of external force such as abominable pressure and impact effectively, avoid optical cable to produce disconnected fine situation effectively, thereby the normal transmission that guarantees the optical cable signal be used; And lay conveniently, processing technology is simple, the yield rate height.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
