Abstract
The invention is a pre-stranded wire type tension-resistant clamp arranged at an end of an optical electric cable. The pre-stranded wire is of a plurality of spiral-like alloy wires and is wrapped on the inner layer steel wire and the outer layer conductive metal wire of the optical electric cable. The diameters of the alloy wires are the same with that of the inner layer steel wire or the outer layer conductive metal wire. The surface of the alloy wire is of anti-slip treatment or is sprayed and bound with quartz sand. Aiming to the structural characteristic of the optical electric cable, the invention adopts multi-group spiral-like alloy wires in layered winding way arranged on the end of the optical electric cable, and the wrapping length is in accordance with the tension of the optical electric cable, thus capable of meeting the erection, traction and fix requirements of the optical electric cable free from layered-peeling and optical electric cable damage accidents.
Description
Technical field
The present invention relates to electric power, communication cable annex, particularly is a kind of annex that is used for optical cable.
Background technology
Optical cable is a kind of novel cable with cable transmitting optical signal and electric energy, has declared the China national patent.Optical cable is made up of the metallic conduction core of electric energy transmitting and the optical fiber or the fiber bundle of transmitting optical signal, and its cross section can be dumb-bell shape, or concentric circles layer strand shape.With the layer-twisted type optical cable is example, and the optical cable center is the reinforcement steel wire, and skin is a conductive metal wire, can be one or more layers, and optical fiber or fiber bundle place between the outer conductive metal wire.Set up, just can not use when installing annex such as the employed wire clamp of general power cable, otherwise delamination, slippage will occur, even damage optical fiber or fiber bundle.
Summary of the invention
Pre reeled silk type strain clamp of the present invention is arranged at the optical cable termination.Form by preformed armor rods, wire clamp, draw ring, preformed armor rods is many spiral helicine alloy silks, and the line footpath of alloy silk directly equates with the internal layer steel wire that twines or the line of outer conductive metal wire respectively on layering, the internal layer steel wire that divides into groups to be wrapped in optical cable, the outer layer metal conductor wire.Alloy silk surface is stained with quartz sand through anti-skidding processing or spray.
The present invention is directed to the design feature of optical cable, adopt the mode that the layering of many group helical form alloy preformed armor rodses is twined to place the optical cable end, coiling length is decided on the optical cable pull-off force, can satisfy the requirement of setting up traction, fixed light cable, the accident of delamination, slippage, damage optical cable can not take place, and guarantees construction quality.

Embodiment
As shown in Figure 1, pre reeled silk type strain clamp of the present invention is arranged at the optical cable termination, by preformed armor rods 2, wire clamp 7, draw ring 6 is formed, and preformed armor rods 2 is that many spiral helicine alloy silks are formed, layering, grouping are wrapped in the internal layer steel wire 3 of the optical cable termination of ladder strip off, and on the outer layer metal conductor wire 2.As shown in Figure 2, the figure center is 7 steel wires 3, and it is outer to be ectonexine conductive metal wire 1, and its outer one deck preformed armor rods 2 that twines has fiber bundle 4 between conductive metal wire 2 and the steel wire 1.As shown in Figure 3, after outer conductive metal wire 1 is peeled off, be wound with two-layer preformed armor rods 2.As shown in Figure 4, after internal layer conductive metal wire 1 is peeled off, be wound with three layers of preformed armor rods 2 outside the steel wire 3 altogether.
Claims (3)
