Abstract
The utility model discloses a carbon-fiber-core fiber wire junction tool comprising a combined sleeve and a clamp connected with the combined sleeve. A double-end connection bolt is disposed at the radial midpoint in the combined sleeve. A clamping surface is disposed on the outer side of the middle part of the double-end connection bolt. The two sides of the double-end connection bolt are in threaded connection with outer taper sleeves. The outer taper sleeve is a cylindrical structure internally equipped with a taper chamber. An inner taper sleeve is disposed in the outer taper sleeve. A plurality of axial opening grooves are disposed on the periphery of the inner taper sleeve. Cable sleeves are disposed on the two ends of the combined sleeve. Part of the cable sleeves are extended out of the combined sleeve. Grooves are disposed in the double-end connection bolt. A sealing ring is disposed on the end portion of the cable sleeve. With the clamp, the carbon-fiber-core fiber wire junction tool may well fix the internal double-end connection bolt. A cable passes through the inner taper sleeve. By compacting and rotating the outer taper sleeves, the gap between two axial opening grooves are forced to be deformed. Therefore, the inner taper sleeve is furled to clamp a wire core so that connection of two wires is achieved. The carbon-fiber-core fiber wire junction tool has characteristics of ingeniously-designed structure, no damage on composite core, easy manipulation, and reliable connection.
Description
Technical field
The utility model belongs to electric system overhead transmission line design field, particularly a kind of carbon fiber core optic fibre wire splicing fitting.
Background technology
In overground cable transmission line of electricity system, two sections of cables are realized continuing and will use wire-connection gold utensil, require connection must meet electric conductivity requirement, meet splicing fitting resistance and be not more than the requirement that equal length is led line resistance, and the requirement that meets wire-connection intensity.Conventional splicing fitting is mainly used in the connection of steel-cored aluminium strand, along with power system technology updates, carbon-fibre wire is with its low arc drop, light weight, transmission loss is few, corrosion resistant superperformance, occupy gradually the significant proportion in transmission of electricity cable, but the composite core of carbon fiber core optical fiber is hard brittle material, its bending strength, tensile strength, and anti-extrusion ability is little, therefore, conventional splicing fitting can not be for the connection of carbon fiber core optical fiber composite overhead wire, therefore, need a kind of novel splicing fitting of design badly and solve above-mentioned technical barrier, improve operating efficiency, reduce construction cost and wire consume.Application number: 201220181173.4 Chinese patent discloses a kind of carbon fiber photoelectric compound wire splicing fitting, described carbon fiber photoelectric compound wire inside is carbon fiber complex core, outside is aluminum conductor, described gold utensil includes contact tube main body, radial midpoint place in described pipe is provided with double end coupling bolt, double end coupling bolt respectively with both sides all symmetrically arranged carbon fiber complex core clamp device be connected, described clamp device front end is provided with filling bushing pipe, and the head end of filling bushing pipe stretches out outside contact tube main body; A hollow hole is set in described contact tube main body; In described contact tube main body, be outside equipped with spiral surrounding striped.The utility model, for connecting the internal layer tension structure combination of carbon fiber complex core, does not need when mounted to carbon fiber complex core crimping, does not damage carbon fiber complex core, and can draw the optical fiber in compound wire, realizes optical fiber separated with transmission pressure.But described double end coupling bolt is difficult for location and controls in installation process with in using, once rotation will be carried out effective clamp operation.
Utility model content
The utility model is to solve above-mentioned technical barrier, and a kind of carbon fiber core optic fibre wire splicing fitting of simple in structure, easy to use, dependable performance is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of carbon fiber core optic fibre wire splicing fitting, comprise combined casing and the holder that is connected combined casing, in described combined casing, radially midpoint arranges the double end coupling bolt that outside, stage casing has clamping face, described double end coupling bolt both sides are threaded with external conical sleeve respectively, described external conical sleeve is the inner column structure that conical cavity is set, the inner conical drogue that all sides have some shaft orientation opening grooves is set in described external conical sleeve, described combined casing two ends arrange the cable sleeve pipe that part is stretched out described combined casing.
Described double end coupling bolt inside arranges groove.
Described cable cannula tip arranges sealing ring.
The utility model has improved prior art, utilize the double end coupling bolt that holder can well fixing internal, adopt combined casing, dismounting is convenient, being convenient to interchangeability substitutes and keeps in repair, in use procedure, wire is inserted from described cable sleeve pipe respectively, through described inner conical drogue, enter in described groove, by compression, rotate described external conical sleeve, force two shaft orientation opening groove gap location distortion, draw described inner conical drogue in, thereby clamping wire core, wire stylet termination respectively with the stressed joint of double end coupling bolt, thereby realize the connection of two section leads, described cable sleeve portion stretches out described combined casing, Bing end arranges sealing ring, prevent inner moisture effect serviceable life.The utility model structural design is ingenious, and two section leads do not need, to the crimping of wire composite core, not damage the composite core of carbon fiber core optical fiber composite overhead wire while connecting, and simple to operate, grip is strong, connects reliably, and result of use is good, has popularizing value.
