Description

Technical Field

[0001] The utility model belongs to the technical field of optical cables, and in particular relates to an optical cable protective cover. Background Art

[0002] In order to change the problem of exposed urban information lines, many cities have adopted underground optical cables for power transmission. At the point where the optical cables pass through the underground, most of them directly pass the optical cables with insulating properties through the underground. Since the optical cables pass through the underground directly, when vehicles collide with the point where the optical cables pass through or people cut the optical cables with a knife, it will cause damage to the optical cables, thus affecting the security of information transmission.

[0003] In order to improve the strength of the optical cable, a common method is to use a polyurethane optical cable protective cover for protection. Please refer to the solution disclosed in Chinese Utility Model Patent 2019219996440. During use, the strength of the polyurethane optical cable protective cover is low and cannot provide good protection for the optical cable. It will be damaged after long-term use, which reduces its service life. Utility Model Content

[0004] The purpose of the utility model is to provide an optical cable protective cover to solve the above-mentioned problems.

[0005] The technical solution adopted by the utility model is: an optical cable protective sleeve, comprising an inner sleeve located inside, a plurality of X-shaped support members evenly distributed along the outer circumference of the inner sleeve, and a plurality of connecting strips connected between the X-shaped support members;

[0006] It also includes a metal wire braided layer located on the outside, the metal wire braided layer wraps the X-shaped support member and the connecting strip;

[0007] A filler is further provided in the area between the two X-shaped support members;

[0008] The inner sleeve is made of polyurethane, and the metal wire braided layer is braided from annealed copper single wires treated with anti-oxidation treatment;

[0009] The X-shaped support member and the connecting strip are integrally extruded into an aluminum profile;

[0010] The filler is a rubber block.

[0011] Beneficial effects:

[0012] By providing an outer metal wire braided layer, an inner polyurethane sleeve, and a supporting ring sleeve, the outer side can be protected from being cut by a knife, while also providing a certain protective effect and increasing the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1 , an optical cable protective sleeve, comprising an inner sleeve 1 located inside, a plurality of X-shaped support members 4 evenly distributed along the outer circumference of the inner sleeve 1, and a plurality of connecting strips 2 connected between the X-shaped support members 4;

[0022] It also includes a metal wire braided layer 3 located on the outside, the metal wire braided layer 3 wraps the X-shaped support member 4 and the connecting strip 2;

[0023] A filler 5 is also provided in the region between the two X-shaped supports 4;

[0024] The inner sleeve 1 is made of polyurethane, and the metal wire braided layer 3 is braided with annealed copper wire with antioxidant treatment, which can protect the outer side from being cut by the knife and play a certain protective effect, thereby improving the service life.

[0025] The X-shaped support member 4 and the connecting strip 2 are integrally extruded into an aluminum profile, which has the advantages of high strength and light weight;

[0026] The filler 5 is a rubber block, which has the effects of filling and anti-deformation.

[0027] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
