Abstract
The utility model provides an optical fiber protector which comprises a compound optical fiber and a protective sleeve, wherein the compound optical fiber comprises a metal tube and an optical fiber; the metal tube is sleeved at the outer side of the optical fiber; the protective sleeve is sleeved at the outer side of the end part of the compound optical fiber; and the optical fiber passes through the protective sleeve. According to the optical fiber protector provided by the utility model, the side of the metal tube has a stronger fixation effect, certain toughness exists between the fracture of the metal tube and the tail end of the protector; the optical fiber is ensured to have a less bending radius when being subjected to a transverse pulling force, and the condition that due to the mis-touch of the optical fiber during construction, the optical fiber is subjected to break-off and cutting damage at the fracture of the metal tube can be effectively relieved.
Description
Technical field
The utility model relates to electric field, especially, relates to a kind of optical fiber protecting equipment.
Background technology
Because optical fiber composite wire (OPPC) is on the phase line of ultra-high-tension power transmission line, to move; Therefore its place of continuing can not leave surplus cable for the use that continues once more; After causing optical fiber composite wire in a single day to block like this; Therefore surplus never again cable just just must consider leave surplus fibre in that connector box is inner, to guarantee welding the molten fine use that continues once more of the fibre core of surplus length can be arranged when off quality enough.But because fibre bundle is in the extremely thin stainless-steel tube of wall thickness, in case transfer to, optical fiber is very easily hurt at the stainless-steel tube incision position, and the optical fiber of dial-out is hindered from steel pipe mouth root is disconnected, does not reach the purpose that leaves surplus fibre.Do not have available protective device at present, can only carefully construct and reduce the loss, but,, in most cases, adopt subsequent use core, cause bigger waste if disconnected core takes place because work high above the ground very easily causes disconnected core.
The utility model content
The utility model purpose is to provide a kind of optical fiber protecting equipment, to solve the technical matters that optical fiber is very easily hurt at the metal tube incision position.
For realizing above-mentioned purpose, the utility model provides a kind of optical fiber protecting equipment, comprises composite fiber, and composite fiber comprises metal tube and optical fiber, and metal tube is set in outer fiber; Protective sleeve, protective sleeve have the spiral body that is formed by the boundary belt winding, and protective sleeve is set in the outside, composite fiber end, and optical fiber passes protective sleeve.
Further, protective sleeve is a flexible material.
Further, flexible material is a nylon sheet.
Further, the two ends of protective sleeve all have opening, and protective sleeve is a taper type.
Further, the wall thickness of protective sleeve awl bottom is greater than the wall thickness of cone top part.
Further, the expansion shape of protective sleeve is trapezoidal, and two trapezoidal hypotenuses are joined together to form protective sleeve.
The utlity model has following beneficial effect: stronger fixation is arranged in the metal tube side; At metal tube fracture to protector end certain toughness is arranged; Guarantee to occur when optical fiber receives lateral pull less bending radius; Can alleviate the construction mistiming effectively and bump optical fiber, cause optical fiber to cause and fracture or the infringement of cutting at the metal tube incision position.
Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the synoptic diagram of the utility model optical fiber protecting equipment;
Fig. 2 is that the protective sleeve of the utility model optical fiber protecting equipment launches synoptic diagram;
Fig. 3 is the synoptic diagram of the protective sleeve of the utility model optical fiber protecting equipment when not using; And
Fig. 4 is the synoptic diagram of the protective sleeve of the utility model optical fiber protecting equipment when using.
Embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1 to Fig. 4, composite fiber, composite fiber comprise metal tube 11 and optical fiber 12, and metal tube 11 is set in optical fiber 12 outsides; Protective sleeve 20, protective sleeve 20 have the spiral body that is formed by the boundary belt winding, and protective sleeve 20 is set in the outside, composite fiber end, and optical fiber 12 passes protective sleeve 20.Boundary belt is the nylon sheet that long 50 millimeters inner wall smooths, outer walls have the 2 millimeters bands in equispaced; In metal tube 11 sides stronger fixation is arranged; At metal tube fracture to protector end certain toughness is arranged; Guarantee when optical fiber receives lateral pull less bending radius to occur, can alleviate the construction mistiming effectively and bump optical fiber, cause optical fiber to cause and fracture or the infringement of cutting at the metal tube incision position.
Referring to Fig. 1 to Fig. 4, protective sleeve 20 is a flexible material, and flexible material is a nylon sheet.Nylon sheet has certain flexibility, increases along with wall thickness increases toughness, therefore in the steel pipe side stronger fixation is arranged.
Referring to Fig. 3 and Fig. 4, the two ends of protective sleeve 20 all have opening, and protective sleeve 20 is a taper type.The wall thickness of protective sleeve 20 awl bottoms is greater than the wall thickness of cone top part.The expansion shape of protective sleeve 20 is trapezoidal, and two trapezoidal hypotenuses are joined together to form protective sleeve 20, and awl bottom wall thickness is 3 millimeters, and the cone top part wall thickness is 1 millimeter.(when not installing) is taper during state of nature, and the awl bottom opening is overlapping, and diameter is 1.5 millimeters between endoporus, 3 millimeters of wall thickness; Vertex of a cone opening is overlapping, 1.5 millimeters of diameter of bores, 1 millimeter of wall thickness.During installation, can wrap up the steel pipe below 3.6 millimeters, general packages length is 25 millimeters.
From above description; Can find out; The utility model the above embodiments have realized following technique effect: in the metal tube side stronger fixation is arranged, at metal tube fracture to protector end certain toughness is arranged, guarantee to occur when optical fiber receives lateral pull less bending radius; Can alleviate the construction mistiming effectively and bump optical fiber, cause optical fiber to cause and fracture or the infringement of cutting at the metal tube incision position.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
