Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to a unit-type indoor and outdoor flat optical cable. Background Art

[0002] Unit-type indoor and outdoor optical cables are a common type of optical cable in communication networks, mainly used to provide high-speed data transmission and stable signal transmission. With the construction and updating of basic communication facilities, the market demand for parallel reinforcement optical fibers with smaller size and good bending performance is increasing.

[0003] The optical cable forming mold in the existing technology is mainly used to process round optical cables. The bending resistance of round optical cables is worse than that of flat optical cables. Round optical cables are prone to twisting, which can easily damage the optical fibers inside the cables. Its main defects are unreasonable internal structural design of the cables, lack of effective tensile reinforcement and protective design, and inability to withstand large tensile forces and external force impacts. In addition, round optical cables are large in size and heavy in weight, which is not conducive to use in confined spaces such as elevator shafts.

[0004] Therefore, there is an urgent need for a unit-type indoor and outdoor flat optical cable to solve the technical defects proposed in the above-mentioned technology. Utility Model Content

[0005] The purpose of the present utility model is to provide a unit-type indoor and outdoor flat optical cable to solve the problem of poor tensile strength mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a unit-type indoor and outdoor flat optical cable, comprising a flat sheath and a movable groove, a movable groove being provided in the flat sheath, a sleeve being movably sleeved in the movable groove, a group of non-metallic reinforcements being arranged on the left and right sides of the flat sheath, a copper wire being arranged inside the left side of the flat sheath, and multiple groups of optical fibers being arranged in the sleeve, and the optical fibers being made of FRP material.

[0007] Preferably, the front and rear ends of the inner wall of the movable groove are both provided with anti-rotation concave walls, and the front and rear ends of the sleeve are both processed into concave arc surfaces, and the anti-rotation concave walls match the concave arc surfaces.

[0008] Preferably, the flat sheath is flat, and the thickness of the flat sheath does not exceed 8.6 mm of the tear sheet.

[0009] Preferably, two groups of non-metallic reinforcements are provided, and the non-metallic reinforcements are arranged in parallel and symmetrically relative to the sleeve.

[0010] Preferably, the optical fiber is located at the center of the inner portion of the sleeve filler.

[0011] Preferably, the outer ring of the optical fiber is filled with a sleeve filler, a tear rope is provided between the outside of the sleeve filler and the sleeve, the sleeve is provided with multiple groups of adhesive grooves at the tear rope, and multiple groups of tear pieces are provided at the edge of the tear rope, and the tear pieces are bonded to the adhesive grooves.

[0012] Preferably, right-angled inner grooves are provided on both sides of the bottom end of the flat sheath, and fixing plates are provided at the bottom of the inner grooves, and fixing bolts are installed at the fixing plates.

[0013] Preferably, the fixing pieces are respectively located at the left rear and right front of the bottom end of the flat sheath, and the fixing pieces are arranged diagonally.

[0014] Compared with the existing technology, the beneficial effects of the present invention are: the unit-type indoor and outdoor flat optical cable not only has high flexibility, good bending performance, and high tensile strength, but also facilitates long-distance vertical laying of the optical cable in the elevator shaft of a super high-rise building, and makes it easier to strip the optical fiber;

[0015] (1) The optical fiber is made of FRP material, which can realize integrated photoelectric transmission. The thickness of the flat sheath does not exceed 8.6mm, which is light in weight and easy to use and lay. The entire optical cable has high flexibility and good bending performance, which is convenient for winding with the elevator. The two sets of non-metallic reinforcements and the copper conductor on one side make the optical cable have high tensile strength.

[0016] (2) By providing a flat sheath, a sleeve, an anti-rotation concave wall, and a fixing bolt, the flat sheath and the sleeve are changed from a fixed sleeve to a movable sleeve. After the anti-rotation concave wall and the concave arc surface of the sleeve are engaged with each other, the number of the flat sheaths can be increased or decreased as needed to facilitate adjustment of the spacing. When the flat sheath is moved, the relative rotation problem between the flat sheath and the sleeve will not occur. The fixed flat sheath is fixed to the elevator shaft with a fixing bolt, and is fixed in a hidden manner, so that the optical cable can be laid vertically over a long distance in the elevator shaft of a super high-rise building.

[0017] (3) By providing a tear rope and a tear sheet, a tear rope is provided at the sleeve, and multiple groups of tear sheets are provided at the tear rope, each tear sheet is embedded in the sticky groove, so that the tear sheet can be quickly torn off from the sticky groove without tools, thereby tearing off the entire tear rope, making it easier to peel off the optical fiber.
