Description
Technical field
The invention belongs to transmission facility technical field, especially a kind of carbon fiber complex core optic fibre wire strain clamp.
Background technology
The research of carbon fiber composite core wire originates in the 1990s, being researched and developed by Japanese scholars, U.S. head in 2004
It is secondary that carbon-fibre wire is applied to transmission line of electricity.Research of the China to carbon-fibre wire starts from 2005, and the wire is in China
First Application is in Liaoning in 2006, the 220000 circuit extending capacity reformations in Fujian.Carbon fiber composite core wire have intensity it is big,
The features such as current-carrying capacity is big, heat-resist, linear expansion coefficient is small, in light weight, corrosion resistance and good, is that a kind of energy-saving and environmental protection type is led
Line, had broad application prospects in overhead transmission line.
Carbon fiber complex core optic fibre wire perfect adaptation carbon fiber composite conductor technology and optical fiber technology so that wire is same
When the function with conveying electric energy and communication, solve the problems, such as that the transmission of optical cable remote large span is difficult, saved resource, fitted
The real-time monitoring to wire running status should can be realized in the development of grid automation.Because carbon fiber complex core optical fiber is led
There is larger difference in the material and structure of line, the structure of original strain clamp is no longer applicable with traditional steel core wire.
Chinese patent CN102364793A is disclosed outside a kind of heavy in section optical phase conductor strain clamp, including clamping
Housing, upper half cone block, lower half cone block and briquetting；Upper half cone block is housed in the clamping shell body first half, in clamping shell body lower half
Portion is equipped with lower half cone block, upper half cone block and the outer wall taper of lower half cone block and matched with the inwall taper of clamping shell body；Pressing from both sides
The side for holding shell body offers grooving, facilitates optical phase conductor to insert, and is also equipped with briquetting in addition, plays fixed optical fiber and answers
Close the effect of aerial phase line.The structure is disadvantageous in that：Optic fibre wire is only fastened by briquetting, does not only exist wire jumper
The problem of, and fastening effect is bad.
Chinese patent CN103500972A discloses a kind of sealing strain clamp of carbon fiber complex core optic fibre wire, in steel anchor
With setting a straight trough on inner cone chuck, silicon rubber protection pipe is embedded in straight trough, one is set on the strip hollow hole of outer tube
Individual sealing port lid, covered in sealing hole and set an aperture, extend a tubular shield in the aperture position of sealing hole exterior surface
Set, the port adhering and sealing plug one for connecting steel anchor to be used in outer tube, in the port bonding that outer tube is used to connect internal lining pipe
Seal plug two, it is located in outer tube on the inwall in internal lining pipe crimping area and multiple ring-shaped stripes is set, the overcoat in crimpless area
The barber-pole stripes being provided around outside pipe.Above-mentioned patent can no doubt play a part of protecting optical fiber, but prolong in aperture position
The silicone rubber tube of stretching is vertical with outer tube, and the silicone rubber tube itself stretched out has 90 ° of angle, in some cases, easily
Cause optical fiber brittle failure.
The content of the invention
In view of this, the purpose of the present invention is in view of the shortcomings of the prior art, there is provided a kind of carbon fiber complex core optical fiber is led
Line strain clamp, by setting arc-shaped through-hole in steel anchor, this structure is set to bear wire tension, fixed wire, and can
Optical fiber is enough protected, prevents optical fiber because exposed and corner is excessive impaired, so as to improve line connection and realize that high-performance is believed
Number transmission function.
To reach above-mentioned purpose, the present invention uses following technical scheme：
Carbon fiber complex core optic fibre wire strain clamp, including wire clip body, steel anchor, it is fixedly connected on wire clip body outer wall
Drainage plate and fiber optic protection box, the wire clip body is hollow tube, and one end in the wire clip body is fixedly connected with wedge grip
Bearing, sets the wedge grip being engaged in the wedge grip bearing, and the other end in the wire clip body sets internal lining pipe, described
Steel anchor is positioned close to one end of wedge grip bearing and is threadedly coupled with wire clip body, and arc-shaped through-hole, institute are set in the steel anchor
The one end for stating arc-shaped through-hole is connected with the wire clip body, and two or more wrapping post is set in the fiber optic protection box.
Further, transparent rubber pipe is set in the arc-shaped through-hole.
Further, the fiber optic protection box is fixedly connected with the steel anchor and set close to the arc-shaped through-hole.
Further, the fiber optic protection box is fixedly connected with the drainage plate and set close to the arc-shaped through-hole.
Further, the wrapping post is four and led to positioned at four ends up and down of same circle, the arc
The left end of the center line in hole and the circle are tangent.
Further, the angle of the tangent line of the intermediate point of the center line of the arc-shaped through-hole and horizontal plane residing for steel anchor is
20-30°。
The beneficial effects of the invention are as follows：
By reserving arc-shaped through-hole in steel anchor, 1. arc-shaped through-hole one end is connected the present invention with the hollow bulb in wire clip body
Logical, the other end of arc-shaped through-hole is connected with the external world, when optic fibre wire runs through arc-shaped through-hole and wire clip body hollow bulb, arc
Through hole is effectively protected to optic fibre wire, avoids causing damage because corner is excessive during optic fibre wire stretching arc-shaped through-hole
Situation occurs；Meanwhile the present invention also sets up fiber optic protection box, fiber optic protection box can use isolation material to determine or draw with steel anchoring
Flowing plate is fixed, and multiple wrapping posts are set in fiber optic protection box, and wrapping post also uses isolation material, is led to when optic fibre wire stretches out arc
Protected when outside hole by the winding further to optic fibre wire of the wrapping post in fiber optic protection box, further prevent optic fibre wire and lose
Phenomenon occur, and fiber optic protection box has certain waterproof, anti-oxidation function, and exposed optical fiber can be protected.
2. the other end in wire clip body is fixedly connected with internal lining pipe, wire clip body compressed after installing
Cheng Zhong, the plastic deformation that the structure design of internal lining pipe effectively prevents wire clip body cause to squeeze wound to optic fibre wire, can be to optical fiber
Wire plays preferable protective action, meets the high quality requirement of optic fibre wire, ensures effectiveness.
3. installing rubber tube in arc-shaped through-hole, collision and abrasion between optic fibre wire and steel anchor are prevented, one can be entered
Step is protected to optic fibre wire.
4. the fixed form of the present invention two kinds of fiber optic protection boxes of design, the first is that fiber optic protection box is fixedly connected with steel anchor
And set close to arc-shaped through-hole, second is that fiber optic protection box is fixedly connected with drainage plate and set close to arc-shaped through-hole, a variety of
Design method can make the present invention select optimum way as the case may be in Practical Project, effectively improve the structure of the present invention
Flexibility.
To sum up, the present invention had both played a part of bearing wire tension, fixing wire for traditional strain clamp, played protection again
The effect of optic fibre wire, optic fibre wire is prevented because exposed and corner is excessive impaired, so as to improve line connection and realization
The function of high performance signal transmission, has not only adapted to the trend of grid automation development, and improves and running shape to wire
Signal reliability when state monitors in real time.
