Abstract
The utility model discloses a pull-resistant optical fiber patch cord comprising a fiber core arranged at the center, wherein the outer side of the fiber core is wrapped with a covering layer, the outer side of the covering layer is provided with a PVC layer, a Kevlar fibrous layer is wound around the outer side of the PVC layer, the outer side of the Kevlar fibrous layer is wrapped with a PVC protection sleeve. The fiber core is protected by a plurality of layers, and the fiber core can be protected from being excessively bent and therefore can be prevented from damage; the patch cord is effectively improved in tensile strength through the Kevlar fibrous layer, the firmness of the patch cord can be protected by the Kevlar fibrous layer, and the fiber core can be prevented from being easily cut by trenchant edges.
Description
Technical field
The utility model patent relates to a kind of optical patchcord, and particularly a kind of anti-pulling drawn optical patchcord.
Background technology
Optical patchcord is used for doing the jumper from equipment to optical fiber cloth wired link.There is thicker protective seam, be generally used in the connection between optical transmitter and receiver and termination box.Optical patchcord (claiming again the joints of optical fibre) refers to that optical cable two ends all load onto connector plug, is used for realizing light path and is flexibly connected; One end is equipped with plug and is called tail optical fiber.(Optical Fiber Patch Cord/Cable) is similar with concentric cable for optical patchcord, just there is no mesh shields layer.Center is the glass core that light is propagated.Fibre core surrounded the glass big envelope that one deck refractive index ratio core is low, so that optical fiber remains on in-core.Outside is the plastic wrapper that one deck is thin again, is used for protecting big envelope.This optical patchcord insufficient strength, in use likely can cause fibre core impaired, and affects the transmission of light signal.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, and a kind of fibre core of effectively protecting is provided, and anti-the pulling that intensity is high draw optical patchcord.
For achieving the above object, the anti-technical scheme of drawing optical patchcord to adopt of pulling of the utility model is:
A kind of anti-pulling drawn optical patchcord, comprises the fibre core at the center of being arranged on, and is coated with covering in the outside of fibre core, has PVC layer in the arranged outside of covering, is wound with Kevlar fabric layer in the outer felt of PVC layer, is coated with PVC sheath in the outside of Kevlar fabric layer.Multilayer protection fibre core, prevents too bending and damaging of fibre core, and Kevlar fabric layer has effectively improved the tensile strength of wire jumper, and Kevlar fabric layer can protect the fastness of wire jumper, prevents that sharp sword from cutting bad fibre core easily.
The inwall of described PVC sheath is provided with wavy fold for fixing Kevlar fabric layer along fibre core trend.
The utility model compared with prior art, have the following advantages: multilayer protection fibre core, prevent too bending and damaging of fibre core, Kevlar fabric layer has effectively improved the tensile strength of wire jumper, and Kevlar fabric layer can be protected the fastness of wire jumper, prevent that sharp sword from cutting bad fibre core easily; The fixing Kevlar fabric layer of fold of PVC jacket inner wall, makes Kevlar fabric layer in sheath, be evenly arranged protection fibre core.
Brief description of the drawings
Fig. 1 is the anti-structural representation that draws optical patchcord that pulls.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present utility model.
Anti-the pulling of one as shown in Figure 1 drawn optical patchcord, comprise fibre 1 core at the center of being arranged on, be coated with covering 2 in the outside of fibre core, there is PVC layer 3 in the arranged outside of covering 2, be wound with Kevlar fabric layer 4 in the outer felt of PVC layer, be coated with PVC sheath 5 in the outside of Kevlar fabric layer, the inwall of described PVC sheath is provided with wavy fold 51 for fixing Kevlar fabric layer along fibre core trend.Multilayer protection fibre core, prevents too bending and damaging of fibre core, and Kevlar fabric layer has effectively improved the tensile strength of wire jumper, and Kevlar fabric layer can protect the fastness of wire jumper, prevents that sharp sword from cutting bad fibre core easily.
Claims (2)
1. anti-pulling drawn optical patchcord, it is characterized in that: comprise the fibre core at the center of being arranged on, be coated with covering in the outside of fibre core, have PVC layer in the arranged outside of covering, be wound with Kevlar fabric layer in the outer felt of PVC layer, be coated with PVC sheath in the outside of Kevlar fabric layer.
2. anti-pulling according to claim 1 drawn optical patchcord, it is characterized in that: the inwall of described PVC sheath is provided with wavy fold for fixing Kevlar fabric layer along fibre core trend.
