Abstract
The invention provides an insulated down lead clamp and relates to a cable clamp, in particular to an insulated down lead clamp for an optical fiber composite overhead ground wire. The insulated down lead clamp comprises a first connection hardware tool, a composite insulator, a second connection hardware tool, an S-shaped fixing clamp or a rod hoop and a binding wire; the first connection hardware tool is installed at one end of the composite insulator, and the second connection hardware tool is installed at the other end; the S-shaped fixing clamp or the rod hoop is installed at the end of the second connection hardware tool; both ends of the binding wire are spiral; and a bayonet is arranged at the middle part of the binding wire and is fixedly matched with the first connection hardware tool. The composite insulator comprises a core rod and an umbrella skirt; and the core rod is installed in the umbrella skirt. The core rod and the umbrella skirt are both made of insulating materials. The rod hoop comprises an upper hoop and a lower hoop. The insulated down lead clamp is stable to install and is convenient to operate and is used for fixing a connection/down lead cable so as to avoid the friction generated between the cable and a tower during operation and also ensure the insulation between the cable and the rod/tower.
Description
Technical field
What insulated down lead clamp of the present invention related to is a kind of optical cable fixture, is a kind of for the Optical Fiber composite overhead Ground Wire insulated down lead clamp.
Background technology
In service at optical cable transmission, the use of optical fiber down lead clip is very common, generally adopts double grip-pieces to come the clamping optical cable, and the fastening of double grip-pieces completed by bolt.There is shortcomings in such design: 1. owing to adopting bolted, screwing force is spent greatly, causes certain wall pressure can for optical cable/wire, thereby cause optical cable/conductive line surfaces impaired, has increased simultaneously installation steps; 2. installation quality is wayward; 3. acceptance of work difficulty is large.
Summary of the invention
The present invention seeks to provides a kind of insulated down lead clamp for above-mentioned weak point, it is a kind of optical cable fixture, be used for the Optical Fiber composite overhead Ground Wire insulated down lead clamp, the present invention has firm, the easy to operate characteristics of installation, optical cable under being used for fixedly continuing/drawing, avoid optical cable to be in operation and tower between produce friction, and guaranteed to insulate between optical cable and bar/tower.
Insulated down lead clamp of the present invention is to take following technical scheme to realize:
Insulated down lead clamp comprises connection gold utensil one, composite insulator, connection gold utensil two, S type fixedly clip or bar anchor ear and wiring.Described composite insulator comprises plug and full skirt, and plug is housed in full skirt.Composite insulator one end is equipped with and connects gold utensil one, and the other end is equipped with and connects gold utensil two, connects gold utensil two ends S type fixedly clip or bar anchor ear are installed, and described bar comprises upper anchor ear and lower anchor ear with anchor ear.Described wiring two ends are provided with bayonet socket and are connected gold utensil one secure fit in the middle part of wiring twist.
When insulated down lead clamp uses, by wiring, optical cable is fixed on and connects gold utensil one top, by the S type fixedly clip be fixed on the angle steel of steel tower with coupling bolt; Or adopt bar with upper anchor ear and the lower anchor ear of anchor ear, be fixed on electric pole by fastening bolt.
It is firm, easy to operate that the present invention has installation.Be used for the lower optical cable that fixedly continues/draw, avoid optical cable to be in operation and tower between generation rub, and guaranteed to insulate between optical cable and bar/tower.
Owing to adopting technique scheme, have following beneficial effect:
1, by wiring is installed, can effectively avoid the suffered wall pressure of optical cable optical fiber in installation process, not producing stress concentrates, increased simultaneously the installation contact area between drop wire clip and optical cable, effectively improve the reliability of wire clamp to the optical cable clamping, reduced the reliability that after date slides along optical cable when using a section;
2, little, the good corrosion resistance of wearing and tearing, need not punch on steel tower, and is easy for installation, and operating efficiency improves.
3, be convenient to acceptance of work personnel inspection installation quality, highly versatile.
Description of drawings
The invention will be further described below with reference to accompanying drawing:
