Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber jumpers, in particular to a novel armored optical fiber jumper. Background Art

[0002] The biggest difference between armored fiber optic patch cord and traditional fiber optic patch cord is that it is specially designed to produce a small flexible stainless steel sleeve to protect the optical fiber, which is easy to break and be damaged.

[0003] Among them, a new type of armored fiber optic jumper with publication number CN216870887U includes an optical cable, the end of which is connected to a connector, the optical cable includes a tight-fitting optical fiber, a porous foam sleeve, a metal armor sleeve and an outer sheath, the porous foam sleeve is coated on the tight-fitting optical fiber, the metal armor sleeve is coated on the porous foam sleeve, and the outer sheath is coated on the metal armor sleeve.

[0004] However, the armor of the existing armored fiber optic patch cord is formed by spirally winding stainless steel belts, so there will be gaps when winding. Although this can protect the optical fiber from physical damage, when the outer protective cover is damaged, some liquids will enter the surface of the optical fiber along the gaps between the stainless steel belts, thereby corroding the optical fiber. Utility Model Content

[0005] In view of the above problems existing in the existing novel armored optical fiber jumper, the present utility model is proposed.

[0006] Therefore, the utility model aims to provide a novel armored optical fiber jumper, which solves the problem that when the outer protective sheath is damaged, some liquid will enter the surface of the optical fiber along the gap between the stainless steel belts, thereby corroding the optical fiber.

[0008] A novel armored optical fiber jumper comprises an optical fiber body, the outer surface of the optical fiber body is surrounded by a waterproof layer, the outer surface of the waterproof layer is surrounded by an armor layer, the outer surface of the armor layer is surrounded by a tensile layer, the outer surface of the tensile layer is surrounded by a flame retardant layer, and the outer surface of the flame retardant layer is provided with a rat and ant proof layer.

[0009] Preferably, the waterproof layer is nylon cloth, and the outer surface of the nylon cloth is coated with polyurethane waterproof coating.

[0010] Preferably, the armor layer is formed by winding stainless steel strips.

[0011] Preferably, the tensile layer is aramid fiber cloth.

[0012] Preferably, the flame retardant layer is a polyethylene heat shrinkable tube.

[0013] Preferably, the rat and ant-proof layer is an insect repellent coating.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model can prevent liquid from flowing from the gap of the armor layer to the optical fiber body by arranging the waterproof layer between the armor layer and the optical fiber body, thereby increasing the service life of the device.

[0016] 2. The utility model provides a waterproof layer on the outer surface of the optical fiber body, which is a nylon cloth with high strength. By applying a polyurethane waterproof coating on the surface, it can have good waterproof performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses a novel armored optical fiber jumper.

[0024] The utility model provides Figure 1-2 A new type of armored fiber optic jumper shown includes an optical fiber body 1, the outer surface of the optical fiber body 1 is surrounded by a waterproof layer 2, the outer surface of the waterproof layer 2 is surrounded by an armor layer 3, the outer surface of the armor layer 3 is surrounded by a tensile layer 4, the outer surface of the tensile layer 4 is surrounded by a flame retardant layer 5, and the outer surface of the flame retardant layer 5 is provided with a rat and ant proof layer 6.

[0025] The waterproof layer 2 is arranged between the armor layer 3 and the optical fiber body 1 to prevent liquid from flowing from the gap of the armor layer 3 to the optical fiber body 1, thereby increasing the service life of the device.

[0026] To prevent liquid penetration, Figure 1-2 As shown, the waterproof layer 2 is nylon cloth, and the outer surface of the nylon cloth is coated with polyurethane waterproof coating.

[0027] Nylon cloth has high strength and can be made to have good waterproof properties by applying polyurethane waterproof coating on its surface.

[0028] In order to protect the optical fiber body 1, Figure 1-2 As shown, the armor layer 3 is formed by winding stainless steel strips, and the tensile layer 4 is aramid fiber cloth.

[0029] The stainless steel bars can prevent rats and ants from chewing the device, while the aramid fiber has excellent properties such as ultra-high strength, high modulus, and light weight, thereby preventing the device from being pulled and damaged.

[0030] In order to prevent the device from burning, Figure 1-2 As shown, the flame retardant layer 5 is a polyethylene heat shrinkable tube.

[0031] Polyethylene heat shrink tubing is a new type of environmentally friendly halogen-free flame retardant tubing that can effectively prevent the device from burning.

[0032] Finally, in order to disperse rats and ants, Figure 1-2 As shown, the rat and ant-proof layer 6 is an insect repellent coating.

[0033] By spraying the insect repellent coating on the surface of the flame retardant layer 5, some creatures such as rats and ants can be repelled.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
