With the improvement of high-speed information transmission requirements, optical fiber is widely used as a high-speed information carrier, and the requirements for optical fiber connection are getting higher and higher, especially in the field of FTTH fiber-to-the-home, high tensile cable connection products. The blank is seriously hindering its development.

In China, a fiber optic cable with a rectangular shape, a center fiber and two reinforcing elements on both sides is listed as the recommended standard household cable. Although the cable has ribs and skin protection, the outer core of the wire core is tight. The size is only 0.25mm thick. When cold docking is required in engineering and actual use, the 0. 25mm fiber is easily injured. When the two fibers are docked and fixed in the cold joint, the tensile strength is less than 5N, so the connection is continued. After the completion, it must be placed in a fixed junction box or a home 86mmX86mm fiber optic panel box, and can not be pulled at will, greatly increasing the difficulty and risk of construction, but also brings hidden dangers to the later maintenance.

A device for connecting a sheathed Fiber Optic Splice Closure , and particularly to a device for connecting a sheathed fiber optic splice closure. The utility model is composed of a box body, a lid and a buckle; a step slot is set in the box body, and the cold joint is pressed into the positioning step slot in the cold fiber optic splice closure body to position the cold joint; the arm body is provided on both sides of the box body The push tube for holding the two ends of the cold joint; the cable ends are arranged at the two end ends of the box body, and the plurality of pairs of the hole slots are arranged on both sides of the slot to match the card legs of the buckle, and are pressed into the hole slots by the buckles to be inserted and placed The fiber sheath in the cable trough, thereby securing the fiber optic cable. The utility model relates to a cold fiber optic splice closure device for connecting a leather wire. The whole hand pressing technology is adopted, and the two leather wires can be firmly docked without using any special tools, the pulling force is greater than 50N, the cable is fastened safely, and the optical fiber is not damaged. No additional insertion loss is generated, and the protection of the optical cable reduces the risk of potential damage; the operation is simple and the construction intensity is small.
