Abstract

The utility model discloses a pre-reeled optical cable down-lead wire clamp component which comprises a clamping piece which is symmetrically provided with a left clamping slot and a right clamping slot; a optical cable is arranged inside the left clamping slot and the right clamping slot; a connecting bolt runs through the center of the clamping piece, and the lower end of the connecting bolt is connected with a fixing piece; a plurality of installation pre-reeled thread groups wound around the optical cable is still included; the installed installation pre-reeled thread groups closely contact the external surfaces of the left and the right clamping slots and the clamping piece is positioned between the optical cable and the installation pre-reeled thread groups. The pre-reeled optical cable down-lead wire clamp component has the advantages that the installation is firm, the contact area with the optical cable or lead is enlarged and the occurrence of unilateral fixation is avoided. The pre-reeled optical cable down-lead wire clamp component is used for fixing the down-lead optical cable when the terminal is connected or the arch formed by the surplus optical cable at an angle pole or a tower, ensuring that a comparatively fixed distance is formed between the optical cable and the pole or tower and preventing the optical cable in operation from being damaged due to the friction generated between the optical cable and the pole or tower. The pre-reeled optical cable down-lead wire clamp component is still applicable to wires or other industries where cables need fixing.

Description

Preformed optical cable drop wire clip assembly

Technical field

The utility model relates to a kind of optical cable anchor clamps, relates in particular to a kind of preformed optical cable drop wire clip assembly.

Background technology

In the optical cable transmission, the use of optical cable drop wire clip assembly is very general, but generally adopts double grip-pieces to come the clamping optical cable, and the fastening of double grip-pieces finished by bolt.There are many shortcomings in such design: 1. owing to used bolted, need use torque spanner according to the installation method of standard, increase installation steps; If 2. the fastening of moment do not meet the requirements, then there is the situation of the tight inadequately situation of bolt or bolted tension even damage; 3. installation quality is wayward; 4. acceptance of work difficulty is big; 5. because the size of intermediate plate is less, and the surface of contact of intermediate plate and optical cable/lead is also very little, and double grip-pieces do not have elasticity, Gu to optical cable fixedly be rigid extruding, then intermediate plate can cause certain wall pressure to optical cable/lead; If bolt is installed tension, this side pressure is more obvious, causes the damage of optical cable/lead easily; 6. common two clamping grooves of double grip-pieces measure-alike when needs draw two fixing down diameters optical cable inequality, monolateral fixation case may occur, and promptly fixed measure is better and the fixing loose partially or tight slightly situation of another side on one side; Occur the vacant situation of groove on one side when only needing to fix an optical cable, reliability is undesirable.

The utility model content

Technical problem to be solved in the utility model is the defective that overcomes prior art, provides a kind of and installs firmly, the contact area of increase and optical cable/lead, avoids occurring the preformed optical cable drop wire clip assembly of monolateral fixation case.

The utility model provides a kind of preformed optical cable drop wire clip assembly, comprise intermediate plate, on described intermediate plate, be arranged with left and right clip slot, optical cable is installed in the described left and right clip slot, coupling bolt is through the central authorities of described intermediate plate, described coupling bolt lower end is connected with fixture, also comprises being used to be wrapped in a plurality of installation preformed armor rods groups that play fixation on the optical cable, and described installation preformed armor rods group contacts with the left and right clip slot intimate of described intermediate plate.

Described intermediate plate is in optical cable and installs between the preformed armor rods group, and described wire clamp jointly realizes by preformed armor rods group and intermediate plate that to the fixing of optical cable described installation preformed armor rods group is made of the many tinsels that are prefabricated into spiral, is wound on optical cable or the lead.By with the cooperating of fixture, fixations such as optical cable, lead are mounted on shaft tower or the body of wall by package unit, about two groups of preformed armor rods groups according to the situation of two optic cable diameters can be identical also can be inequality.

Described fixture adopts suitable multiple installation component according to applicable situation, as the U-shaped clamping plate, is provided with through the erection bolt of described U-shaped clamping plate inside groove at an avris of described U-shaped clamping plate, is used for that wire clamp is connected with the lattice iron tower and fixes; Described fixture is a bar anchor ear assembly, comprises splayed web member and annular anchor ear, and described annular anchor ear is an adjustable stainless steel band anchor ear or can not the zinc-plated anchor ear of mode; Described fixture is the bar bolt assembly, is used for wire clamp and the cement pole that preformed hole is arranged, steel tube tower (iron) and rod or the rod that can punch is connected and fixing, perhaps is used for being connected of wire clamp and body of wall.

Owing to adopt technique scheme, the utlity model has following beneficial effect:

1, by the preformed armor rods group is installed, the monolateral phenomenon that forms in the time of can avoiding the isometrical intermediate plate of double flute to install effectively, vacant monolateral of one side groove that forms in the time of especially only need fixing an optical cable greatly improved the reliability of installing;

2, the mounting means of preformed armor rods group makes that the suffered wall pressure of optical fiber in the optical cable is almost nil, not producing stress concentrates, increased the installation contact area between drop wire clip and the optical cable simultaneously, improved the reliability of wire clamp effectively, reduced the possibility that after date slides along optical cable when using a section the optical cable clamping;

3, the mounting means of preformed armor rods group makes installation efficient improve greatly, and it is very convenient to operate;

4, preformed armor rods group mounting means is convenient to acceptance of work personnel inspection installation quality.
