Abstract
The utility model relates to a sheathed tail fiber and a communication sensing optical cable, which is applied to the fields of data transmission, optical fiber temperature, optical fiber and optical grating sensing, communication transmission and sensing optical cable in a communication machinery room. The utility model is composed of a tight tube optical fiber, a spiral stainless steel tube, a Kevlar fiber, a stainless steel wire braid, a PVC coating layer and a copper wire braid at the external layer, wherein the tight tube optical fiber is positioned at the center of the optical cable, the external layer of the tight tube optical fiber is the spiral stainless steel tube, the outside of the stainless steel tube is additionally provided with the Kevlar fiber for strengthening tensile strength, the external layer of the Kevlar fiber is the stainless steel wire braid, the outside of the steel wire braid is the PVC coating layer and the outermost layer is the copper wire braid. Due to the adoption of the structure, the utility model has the advantage that the compression resistance, the tensile strength, the torsion resistance, the rat proofing and the external force damage prevention of the communication sensing optical cable can be enhanced and can achieve the purpose that the optical cable can safely work without faults for a long time.
Description
Technical field
The utility model relates to the communications and the sensing optic cable field of the data transmission that is applied to communications equipment room and fiber optic temperature, optical fiber grating sensing, refers in particular to a kind of armouring tail optical fiber and communication sensing optic cable.
Background technology
Because optical cable can carry the lot of data signal when the transmission data information, so reaching the communications equipment room transmission at a distance, when use in the optical fiber sensing field, be to replace general traditional information transmission line now with optical fiber.Optical fiber with the most amount of Optical Fiber Transmission data packet, is understood reciprocity data packet with switch or sense instrument when the transmission data again; Therefore when utilizing Optical Fiber Transmission data and signal, must guarantee the laying between optical fiber and switch or the sense instrument and be connected with enough firm endurance qualities, make the interior sub-optical fibre of optical cable can safe, long-term each other work.
Make a general survey of present common communications sensing optic cable; owing to be subjected to external pulling force, pressure, rub, reverse, influence such as environmental corrosion produces optical fiber to disconnect the problem that data-signal is interrupted comparatively outstanding, therefore provides strong protection to become extremely important for common tail optical fiber and communication sensing optic cable.
The utility model content
In order to solve the weak point in the above-mentioned technology, the utility model provides a kind of new armouring tail optical fiber and communication sensing optic cable, and this brand-new structure can further improve the soundness and the permanance of optical cable.
It comprises the utility model: tight tube fiber, PVC coating is characterized in that: be provided with spirality stainless-steel pipe, kevlar fiber and stainless steel steel wire braid between tight tube fiber and PVC coating successively.
Above-mentioned PVC coating is arranged with layer of copper silk braid outward.
The beneficial effects of the utility model are:
1, tight tube fiber increases the spirality stainless-steel pipe outward, has greatly improved compressive strength.
2, steel pipe increases kevlar fiber outward, has improved tensile strength.
3, kevlar fiber increases the stainless steel steel wire braid outward, has improved the antitorque characteristic of optical cable.
When 4, outermost layer copper wire braid is applied in grating sensing, can guide static, eliminate potential electrostatic spark.
5, be applied in communications equipment room and when exchange transmission, can not use outermost layer copper wire braid, can play the effect of effective protection against rodents, anti-outside destroy equally.
6, be applied in the optical fiber sensing field, can play the trouble-free effect of long-term safety work.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a cut-open view of the present utility model.
Among the figure: 1-tight tube fiber, 2-spirality stainless-steel pipe, 3-kevlar fiber, 4-stainless steel steel wire braid, 5-PVC coating, 6-copper wire braid.
Embodiment
As shown in Figure 1, the utility model comprises tight tube fiber 1, spirality stainless-steel pipe 2, kevlar fiber 3, stainless steel steel wire braid 4, PVC coating 5, outer copper wire braid 6.
Described tight tube fiber 1 is positioned at the optical cable center, optical cable center skin is that increase one deck kevlar fibers 3, kevlar fiber 3 skins are to be that PVC coating 5, outermost layer are that 6, six ingredients of copper wire braid are formed according to frame mode from inside to outside outside stainless steel steel wire braid 4, the stainless steel steel wire braid 4 outside spirality stainless-steel pipe 2, the stainless-steel pipe 2.
Certainly, above-described embodiment is preferred embodiment of the present utility model, is not to be used for limiting the utility model practical range.So all equivalences of doing according to the described structure of the utility model claim, feature and principle change and revise, and all should be included within the utility model application protection domain.
