Detailed Description

The following describes embodiments of the present invention in further detail with reference to the drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be construed as limiting the present invention. In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 3-6, the aerial steel strand for optical cables according to this embodiment includes a steel strand body 1 and a sheath 7 covering the outside of the steel strand body 1, the material of the sheath 7 is PE, a plurality of sets of optical cable hook limiting sections 8 are uniformly distributed on the sheath 7, each set of optical cable hook limiting section 8 includes two limiting rings, each limiting ring includes at least four protrusions 9 uniformly distributed along the circumferential direction of the cross section of the sheath 7, each protrusion 9 is hemispherical, the height of the preferred protrusion 9 is 5mm, the purpose of limiting the optical cable hook 3 is achieved without affecting the steel strand body 1 to enter a straightener, and the protrusions 9 are integrally disposed on the sheath 7 or bonded on the sheath 7; the limiting sections 8 of the optical cable hooks are respectively provided with two wear-resistant bushings 10 matched with the optical cable hooks 3, each wear-resistant bushing 10 comprises a cylindrical bushing body 11 and two annular elastic sheets 12 embedded in the bushing body 11, the bushing body 11 and the elastic sheets 12 are correspondingly provided with slits 13, the wear-resistant bushings 10 are convenient to disassemble and assemble on the sheaths 7, specifically, the wear-resistant bushings 10 are not assembled on the sheaths 7 of the steel strand bodies 1 stretched out from the wire coils in a construction site and before entering a straightening machine for straightening, workers quickly assemble the wear-resistant bushings 10 on the sheaths 7 through the slits 13 and the annular elastic sheets 12 after straightening, the bushing bodies 11 and the annular elastic sheets 12 are respectively made of TPU and spring steel, the TPU has excellent wear resistance and weather resistance, can effectively avoid the optical cable hooks 3 from contacting the sheaths 7 to wear the sheaths 7 when the TPU is slowly aged, after the installation of the optimized wear-resistant bushing 10 is completed, the peripheral surface of the wear-resistant bushing 10 is flush with the peripheral surface of the sheath 7, the two metal hooks 6 of the optical cable hook 3 are prevented from being heightened, and the normal limiting effect of the limiting ring is ensured.
