Claims

[Scope of utility model registration request]

In a closure whose main components are a sleeve in which two semi-cylindrical bodies are removably connected to face each other and a rubber end plate having a cable insertion hole that is airtightly attached to each end of the sleeve, a pair of cable jacket grips are provided inside the sleeve. The fittings are connected by two connecting rods that are parallel to the axis of the sleeve and each individually connected to both sides of the gripping fitting, and in the center of the connecting rod there is a tensioner placed at the center of the cable connection part. A semi-cylindrical excess length storage shell with an axially symmetrical notch that supports the member fixing bracket and is closer to both ends than the bracket is hung and installed. Furthermore, a thin, springy, semicircular excess length guide with locking protrusions for the connecting rod on both side edges is attached to the connecting rod at a location corresponding to the notch, and protrudes upward. In the space formed between the long storage shell and the extra length guide,
A closure for an optical fiber cable, characterized in that it is configured to store the excess length of an optical fiber wrapped in a film sheet and rolled into a circle together with the sheet.
