The optical fiber in an optical unit is butted with high intensity and identical length; an optical unit protecting tube (2) is tightly matched and fixedly connected with an optical unit matching metal tube (3) sleeved outside the optical unit protecting tube (2); a metal pre-twisted wire (4) is twisted outside the optical unit matching metal tube (3); an outer layer twisted wire (5) is reversely twisted on the outer layer of the metal pre-twisted wire (4); anti-strand loosing and locking cover nuts (6) cover the two ends of the outer layer twisted wire (5), and the fixed connection is the close fit between the outer layer twisted wire (5) and the cover nuts (6). The on-line flexible splice box of the invention is widely used as the splicing device for the optical fiber composite overhead ground wire, and has the advantages that the on-line flexible splice box can not be limited by the length of a distribution disk and a splicing position, splicing can be performed in any position of the optical fiber composite overhead ground wire cable, the optical fiber is not easy to be stolen and damaged, the resources are greatly saved, and the construction intensity and the construction cost are reduced.
Description
Affiliated technical field
The present invention relates to a kind of facility splice tray that continues of Optical Fiber composite overhead Ground Wire, the flexibility that is used for structure and is the Optical Fiber composite overhead Ground Wire circuit optional position of pipe core light unit, individual layer twisted wire structure continues, i.e. the online flexible switching box of Optical Fiber composite overhead Ground Wire.
Background technology
Optical Fiber composite overhead Ground Wire is the aerial earth wire that contains optical fiber, and the main three parts by optical property, mechanical property and electric property that continue of Optical Fiber composite overhead Ground Wire are connected.Traditional Optical Fiber composite overhead Ground Wire splice tray only possesses the function that optical property connects, therefore must be installed on the shaft tower, finish being electrically connected of Optical Fiber composite overhead Ground Wire by the grounding body on iron tower itself or the cement shaft tower, the gold utensil strain clamp that the connection of mechanical property then relies on the shaft tower both sides bears the tension force of straining cable.In transmission line of electricity, most shaft tower can only bear the power of vertical direction and can not bear the out-of-balance force of horizontal direction, Optical Fiber composite overhead Ground Wire must continue on the shaft tower that can bear the horizontal direction unbalanced tensile force, this has just caused every dish length of Optical Fiber composite overhead Ground Wire to depend on two distances between the load shaft tower, and a plurality of factors such as the difference of height of the sag of this length and Optical Fiber composite overhead Ground Wire, landform, shaft tower and distance error are directly related.Carry out on ground because of continuing, also will increase the excess length on cat head and ground.So the splice locations of arrangement Optical Fiber composite overhead Ground Wire need be carried out very strict " joining dish " or " joining length " design.This design is peaceful long not short, then would rather leave bigger length plus tolerance when producing delivery, causes the waste of ample resources.In addition, individualism and be fixed on splice tray on the shaft tower also easily by artificial destruction even stolen and influence proper communication.
Summary of the invention
Be only limited on shaft tower and continue in order to overcome existing fiber composite overhead ground wire splice tray, need join dish specially and join long design, excess length is big, resource is wasted in a large number, is contained in easily destroyed and stolen etc. the deficiency of splice tray on the shaft tower, the invention provides a kind of online flexible switching box of Optical Fiber composite overhead Ground Wire, making it does not joined dish length and splice locations limits, simplify and join the dish design, save resource in a large number, reduce construction intensity and reduce construction cost.
The present invention solves the technical scheme that its technical matters takes: the isometric butt joint of optical fiber high strength in the light unit; The connection that is tightly fixed of the coupling metal tube of light cell protection Guan Yuqi overcoat; The outer stranded metal preformed armor rods of light units match metal tube is at the outer hank knotting of its outer reverse stranding; Outer hank knotting two ends tightly put anti-broken lot lock sleeve cap and fixedly connected.Above-mentioned described smooth units match metal tube internal diameter is connect light cell protection external diameter of pipe with quilt and is equated, is the connection that is tightly fixed therebetween; The outer stranded metal preformed armor rods diameter of above-mentioned described smooth units match metal tube is connect the outer hank knotting equal diameters of aerial earth wire with quilt, and strand is to identical; Above-mentioned described strand tightly the outer hank knotting outside preformed armor rods to cover the length that is connect the outer twisted wire of Optical Fiber composite overhead Ground Wire be 1～5 times of metal preformed armor rods length, with the preformed skein silk of metal to opposite, be the connection that is tightly fixed therebetween; Above-mentioned described outer hank knotting two ends are with 0.1～3 times anti-broken lot lock sleeve cap of metal preformed armor rods length respectively, are fixedly connected therebetween; The anticorrosion ointment of filling between above-mentioned described preformed armor rods and the outer hank knotting and in the gap between outer hank knotting and the anti-broken lot lock sleeve cap.
Advantage of the present invention is owing to being flexible, can stay on the load shaft tower with certain radius-of-curvature dish, can be used as " wire jumper " joint between two strain clamps in shaft tower both sides, online the continuing in the middle optional position of circuit that also can continue between two shaft towers no longer has the notion of traditional splice tray, outward appearance after the present invention continues is just as one section thicker slightly Optical Fiber composite overhead Ground Wire, the restriction of not joined dish length and splice locations is simplified and is joined the dish design.Optical property was better than traditional splice tray index after integral body of the present invention continued, and mechanical tensile strength is not less than by 95% of jointed fiber composite overhead ground wire, and electric conductivity is better than by the jointed fiber composite overhead ground wire.The present invention is widely used as the connection device of Optical Fiber composite overhead Ground Wire, can save resource in a large number, reduces construction intensity and reduces construction cost.
