Further, the tight sleeve sheath is made of transparent polyamide PA12, and the outer sheath is made of transparent thermoplastic polyurethane elastic material.

The self-adhesive invisible optical cable has a unique structure, adopts the special-shaped outer sheath, has at least one edge and adopts a concave arc line structure, so that the outer sheath has at least one concave arc surface extending along the axial direction; meanwhile, the outer sheath is made of soft elastic materials, so that the concave arc surface can be attached to and adsorbed on a smooth laying surface after being deformed by pressing the optical cable in the optical cable laying process. The special-shaped optical cable is optimized in structure and convenient to lay, and does not need other complex fixing structures, so that the special-shaped optical cable has a certain invisible effect in appearance after being laid, and meanwhile, the production and wiring costs are greatly reduced.

Especially, the cross-section main part design when the oversheath is for being isosceles right triangle-shaped form, and when two right-angle sides were concave pitch arc, the optical cable formed two concave arc faces along axial extension, this shape was laid the face phase-match with glossy right angle corner, press down the optical cable when laying, make two concave arc faces can warp the back, it is attached and adsorb on glossy right angle corner is laid the face, triangle-shaped optical cable just can the adhesion in corner department like this, seem more difficult quilt to perceive, play better stealthy effect.

Further, when the tight-sleeved sheath is made of transparent polyamide PA12 material and the outer sheath is made of transparent thermoplastic polyurethane elastic material, the optical fiber, the tight-sleeved sheath and the outer sheath are transparent, so that the optical cable is not easy to identify, and the best invisible effect is obtained.

Compared with the prior art, the utility model has novel and simple structure, can adsorb self-adhesion and has certain invisible characteristic after being laid; especially, when the main body of the section of the outer sheath of the optical cable adopts an isosceles right triangle with a concave arc line, each surface of the outer sheath is a concave arc surface; when the optical fiber, the tight-sleeved sheath and the outer sheath are made of transparent materials; at the right-angle corners of various buildings, especially the existing buildings have a plurality of transparent glass frames, the appearance structure of the optical cable of the utility model is matched with the right-angle wall corner; the right-angle surface of the optical cable can be adsorbed on the wall corner of the right-angle glass through extrusion force, and wiring can be completed without any fixture. And the concave cambered surface that the hypotenuse corresponds is the arc curved surface of longer relatively, and the optical cable can be adsorbed in smooth surface of laying through its single face and fixed the optical cable. Meanwhile, the concave arc surface of the optical cable can have larger adsorption force by increasing the length of the concave arc surface.

The tight-buffered optical fiber is positioned at the geometric center of the optical cable, and the triangular structure of the outer sheath also has excellent and stable lateral pressure resistance.

Detailed Description

The invention is further described with reference to the following figures and examples.

Fig. 1 shows a self-adhesive invisible optical cable, which comprises an outer sheath 1 and an optical unit, wherein the outer sheath is made of soft elastic material. The main section of the outer sheath 1 is in the shape of an isosceles right triangle, and three sides are concave arcs, so that the outer sheath has three concave arc surfaces extending along the axial direction: two right-angled side concave arc surfaces 101 and a hypotenuse concave arc surface 102; two right-angle side concave arc 101 make the optical cable can match the laminating, adsorb on the smooth face of laying at right-angle corner, and hypotenuse concave arc 102 makes the optical cable can single face match the laminating, adsorb and fix the optical cable on smooth face of laying.

The optical unit is a tight-buffered optical fiber and comprises a tight-buffered sheath 2 and an optical fiber 3. The tight sleeve sheath 2 is made of transparent polyamide PA12, and the outer sheath 1 is made of transparent thermoplastic polyurethane elastic material. When the optical fiber 3, the tight-sleeved sheath 2 and the outer sheath 1 are made of transparent materials, the optical cable appearance structure is matched with a right-angle corner at a right-angle corner of various buildings, especially the corner positions of a plurality of transparent glass frames in a glass building material space widely used in modern buildings, the right-angle surface of the optical cable can be adsorbed on the right-angle glass corner through extrusion force, wiring can be completed without any fixed object, and due to the fact that the optical cable materials are made of the transparent materials, an excellent invisible effect can be obtained, especially when the glass frames are used, the perfect effect which is difficult to achieve by other existing products is achieved.

Certainly, the tight-sleeved sheath 2 and the outer sheath 1 can be made of soft elastic materials instead of transparent materials due to different design and engineering requirements as long as the outer sheath 1 is made of soft elastic materials; the cross section of the outer sheath 1 is shaped in a special way, and at least one edge of the outer sheath is a concave arc line, so that at least one concave arc surface extending along the axial direction can be formed on the surface of the outer sheath 1; in the process of laying the optical cable, the optical cable is pressed to enable the concave arc surface to be deformed and then be attached to and adsorbed on the smooth laying surface, for example, the main section of the outer sheath 1 is in an isosceles right triangle shape, but only the bevel edge is a concave arc line and the right angle is designed to be in fillet transition, so that the optical cable is laid and adsorbed on the smooth laying surface through the only concave arc surface, and the appearance effect of laying can also achieve a good invisible effect; or, the main section body of the outer sheath 1 is in an isosceles right triangle shape, but only two right-angle sides are concave arc lines, while the bevel edge is not designed to be a concave arc line, and the optical cable can be laid and adsorbed at the right-angle wall corner in a matching way; even the main body of the cross section of the outer sheath 1 can be chosen from other shapes according to the engineering requirements, as long as the cross section of the optical cable at least comprises one side, and the side is set to be a concave arc line.

The light unit may also take other existing forms of construction than tight-buffered optical fibre, depending on engineering requirements.

Although the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
