Abstract
The utility model relates to an anti-mouse-bite soft optical cable, which is formed by that a tightly packaged optical fiber of an inner core of the optical cable is additionally provided with an aramid fiber, a chinlon, a glass fiber or other high-strength yarn reinforced layer which is in parallel with an optical cable shaft so as to enhance the axial stretching resistance of the utility model. The outside of the utility model is packaged with a metal tape with an S-shaped cross section rolled by steel, copper and stainless steel metal tape, the adjacent curlings of the metal tape are mutually embedded and are helically and continuously wrapped into a corrugated metal tape protective layer. The outside of the metal tape protective layer is squeezed with a layer of polyvinyl chloride, polyethylene, polypropylene or polyurethane soft outer protective layer. The utility model has the advantages that the tightly packaged optical fiber is protected in the continuously wrapped metal tape protective layer, so that the side compression resistance and the smash-proof capability of the optical cable can be enhanced, the possibility of optical fiber broken bitten by animals, such as mice, etc., can be avoided and normal and smooth operation of optical communication can be ensured.
Description
Affiliated technical field
The utility model relates to a kind of optical communication cable, and is particularly a kind of not only soft but also can prevent effectively that the optical communication cable of being bitten broken by mouse from being the mouse bite preventing flexible optical cable.
Background technology
Inside cable commonly used at present mostly is inner greatly and adds the reinforcement of aramid fiber yarn by one or a few tightly packaged fiber, squeezes into pvc sheath again and forms.Though this optical cable is soft, and is easy to manufacture, to be convenient to crooked the installation and to lay, its weak point is not possess the protection against rodents function, is often bitten broken by animals such as mouse in actual application and influences the normal operation of optical fiber communication.
Summary of the invention
In order to overcome that existing flexible optical cable is easily bitten broken by mouse and the deficiency that influences the normal operation of optical communication, the utility model provides a kind of flexible optical cable, this flexible optical cable is not only soft, be convenient to crooked construction and installation, and can prevent reliably that optical cable from not bitten broken by animals such as mouse, guarantee the reliable normal operation of optical communication.
The technical scheme that its technical matters that solves the utility model adopts is: tightly packaged fiber adds the yarn enhancement Layer with axially parallel, to strengthen axial stretching resistance, its outer wrapped corrugated metal band sheath, this metal tape sheath can be by steel, copper, the rolling adjacent crimping of the S-shaped crimping metal tape of xsect of stainless steel metal embeds mutually, wrapped continuously with spirality, to strengthen its radially compressive resistance, effectively prevent to be bitten broken optical cable by animals such as mouse, periphery at wrapped metal tape sheath extrudes one deck Polyvinylchloride, tygon or flexible polyurethane outer jacket, the inner core tightly packaged fiber of above-mentioned described flexible optical cable can be single or many, and the yarn of above-mentioned described yarn enhancement Layer can be an aramid fiber, polyamide fibre, the yarn that terylene or glass and so on tensile strength is high.
The beneficial effects of the utility model are owing to added the wrapped metal tape sheath of one deck in sheath; in the soft bending that has kept flexible optical cable freely; when being convenient to the installation characteristic; the anti-side pressure of optical cable, the anti-ability that injures by a crashing object have been increased again; guarantee to have stopped to be bitten broken by mouse the possibility of optical cable, the tooth of mouse is severe again, the absolutely not metal tape sheath of breaking by the teeth; fiber cores is covered by metal tape sheath inboard and is subjected to reliably protecting, thereby guarantees the normal operation of optical communication reliably.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model cross-sectional view.
In Fig. 1,1. tightly packaged fiber 2. strengthens thread layers, the 3. wrapped corrugated metal of spiral band sheath, 4. outer jacket.
Embodiment
In Fig. 1, the periphery of tightly packaged fiber (1) adds the thread layers (2) of applying one deck and axially parallel, it is outer to be the continuous wrapped corrugated metal band sheath of spirality (3), this metal tape sheath (3) can be by steel, copper, stainless steel S shape crimping metal tape, adjacent crimping embeds mutually, wrapped continuously with spirality, the periphery of corrugated metal band sheath extrudes one deck Polyvinylchloride, tygon or polyurethane material outer jacket (4), above-mentioned described tightly packaged fiber (1) can be single or many, above-mentioned described and fiber axis can be aramid fibers to the yarn of parallel lay-up, polyamide fibre, terylene, the yarn that the tensile strength of glass and so on is high is to strengthen the axial stretching resistance of flexible optical cable.
Claims (5)
1, a kind of mouse bite preventing flexible optical cable adds the enhancing thread layers by the tightly packaged fiber inner core, and the wrapped corrugated metal of spiral band sheath and outer jacket are formed, and it is characterized in that adding the yarn enhancement Layer that applies with axially parallel at tightly packaged fiber its outer continuous wrapped metal tape sheath.
2, mouse bite preventing flexible optical cable according to claim 1 is characterized in that described wrapped corrugated metal band sheath is that the adjacent crimping of the S-shaped crimping metal tape of xsect that is rolled into by steel, copper, stainless steel strip embeds mutually, and is wrapped continuously with spirality.
3, mouse bite preventing flexible optical cable according to claim 1 is characterized in that the periphery at described wrapped corrugated metal band sheath extrudes the soft outer jacket of one deck Polyvinylchloride, tygon or polyurethane material.
4, mouse bite preventing flexible optical cable according to claim 1, the tightly packaged fiber that it is characterized in that described flexible optical cable inner core can be single or many.
5, mouse bite preventing flexible optical cable according to claim 1, the yarn that it is characterized in that described yarn enhancement layer can be the high yarns of aramid fiber, polyamide fibre, terylene or glass and so on tensile strength.
