Abstract
The utility model discloses a dustproof optical fiber patch cord The dustproof optical fiber patch cord comprises an optical cable and plug heads, wherein the plug heads are connected onto two ends of the optical fiber; the plug heads comprise fiber cores and positioning sleeves; the positioning sleeves and the fiber cores are arranged in a concentric manner, screw nuts are movably connected outside the positioning sleeves, the positioning sleeves are integrated with an outer side protection sleeve of the optical fiber through thermoplastic caps, the tail parts of the positioning sleeves are provided with protruding loops used for limiting the screw nuts, the tail parts of the screw nuts are provided with back-up rings which are connected with the protruding loops in a clamped manner, and sealing rings are arranged at the rear sides of the protruding loops. When the plug heads are connected with devices, the sealing rings are extruded by the back-up rings of screw bolts, sections of the sealing rings deform, gaps between the screw nuts and the positioning sleeves are effectively sealed, dust can be prevented from entering the fiber cores, and stable signal transmission of the patch cord can be guaranteed.
Description
Technical field
The utility model patent relates to a kind of optical patchcord, particularly a kind of dustproof optic fibre wire jumper.
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 plug, is used for realizing light path and is flexibly connected, and 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.The two ends plug of the optical patchcord of prior art is owing to being to be flexibly connected, and dust easily enters plug and is attached on fibre core and causes the loss of signal.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, provides one can effectively protect fibre core, prevents that dust from entering fibre core and affecting the dustproof optic fibre wire jumper that signal transmits.
For achieving the above object, the technical scheme that the utility model dustproof optic fibre wire jumper adopts is:
A kind of dustproof optic fibre wire jumper, comprise optical cable and the plug that is connected to optical cable two ends, described plug comprises fibre core, locating sleeve with the concentric setting of fibre core, outside at locating sleeve is connected with nut, described locating sleeve and the lateral sheathed of optical cable connect as one by thermoplastic cap, the afterbody of described locating sleeve is provided with the bulge loop of restriction nut, and the afterbody of nut is provided with the back-up ring engaging with bulge loop, is provided with O-ring seal at the rear side of bulge loop.When attachment plug and equipment, the back-up ring crush seal circle of bolt, O-ring seal cross section deforms, and by the gap effective sealing between nut and locating sleeve, prevents that dust from entering fibre core, has ensured the signal stabilization transmission of wire jumper.
The inner side of described locating sleeve is fitted with PVC layer.The PVC layer of locating sleeve produces the socket effective sealing of suitable distortion and equipment, and PVC layer has the function of anti-attrition, and the plug that makes to come in and go out is more smooth and easy.
The utility model compared with prior art, has the following advantages: when attachment plug and equipment, and the back-up ring crush seal circle of bolt, O-ring seal cross section deforms, by the gap effective sealing between nut and locating sleeve, prevent that dust from entering fibre core, ensure the signal stabilization transmission of wire jumper; The PVC layer of locating sleeve produces the socket effective sealing of suitable distortion and equipment, and PVC layer has the function of anti-attrition, and the plug that makes to come in and go out is more smooth and easy.
Brief description of the drawings
Fig. 1 is the structural representation of dustproof optic fibre wire jumper.
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.
A kind of dustproof optic fibre wire jumper as shown in Figure 1, comprise optical cable 1 and the plug 2 that is connected to optical cable two ends, described plug comprises fibre core 21, locating sleeve 22 with the concentric setting of fibre core, the inner side of locating sleeve is fitted with PVC layer 28, be connected with nut 24 in the outside of locating sleeve, described locating sleeve and the lateral sheathed of optical cable connect as one by thermoplastic cap 23, the afterbody of described locating sleeve is provided with the bulge loop 25 of restriction nut, the afterbody of nut is provided with the back-up ring 26 engaging with bulge loop, is provided with O-ring seal 27 at the rear side of bulge loop.When attachment plug and equipment, the back-up ring crush seal circle of bolt, O-ring seal cross section deforms, and by the gap effective sealing between nut and locating sleeve, prevents that dust from entering fibre core, has ensured the signal stabilization transmission of wire jumper.
Claims (2)
