Abstract

PURPOSE:To contain easily a surplus length part, also to prevent the surplus length part from falling into pieces in a surplus length containing tool, and to take it out in good order by providing a pair of holding piece forming slits so as to be opposed to each other in each opposite direction, on a sheet. CONSTITUTION:Holding piece forming slits 5, 6 for forming a pair of holding pieces 3, 4 are provided so as to be opposed in each opposite direction, on a sheet body 2. Round holes 7, 8 for raising easily the holding pieces 3, 4 and also obstructing an expansion of the slits 5, 6 are formed in the end part of the slits 5, 6. A connecting part holder 9 is stuck or fixed by a clamping ring, etc. onto the body 2 so as to be adjacent to one holding piece 4. In this state, a surplus length part 10A is formed like a loop and held by the holding pieces 3, 4 and the body 2. Also, a fiber connecting part 11 is supported by the holder 9. Subsequently, the surplus length part 10A is contained in a surplus length containing tool, in a state that it has been held by a surplus length holding sheet 1. Accordingly, a containing work is executed easily, also the surplus length part can be prevented from falling into pieces in the containing tool, and also it can be taken out in good order from the containing tool.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an optical fiber excess length holding sheet that holds the excess length of a coated optical fiber, an optical fiber cord, or the like.

(Prior art) At 111 points where optical fibers are connected, Hg
Extra length is provided in advance for the optical fibers, etc. to allow for reconnection. The extra length of the optical fiber is generally stored in an extra length storage tool in the form of a loop.

(Problem to be Solved by the Invention) In this case, the extra length was simply rolled into a loop and inserted into the extra length storage tool, so the loop was likely to become disordered and come apart inside the extra length storage tool. It had the disadvantage that it could not be stored in an orderly manner. Although it is possible to store items in an orderly manner by tying the extra length of the loop, the tying process has the disadvantage that it is time-consuming.

SUMMARY OF THE INVENTION An object of the present invention is to provide an optical fiber surplus length holding sheet that can store the surplus lengths of optical fibers in an orderly manner and can be carried out easily and at low cost.

(Means of the present invention for solving the problems) The optical fiber extra length holding sheet according to the present invention has a sheet main body in which holding piece forming slits forming a pair of holding pieces face each other in opposite directions. It is characterized by the fact that it is provided.

(Function of the Invention) Such an optical fiber extra length holding sheet forms an extra length of the optical fiber core into a loop shape and is held between both holding pieces and the sheet body. The extra length storage tool holds the extra length portion with this extra length holding sheet and stores it therein. Therefore, the extra length part can be easily stored in the extra length storage tool, the extra length part can be prevented from falling apart in the extra length storage tool, and it can be taken out in an orderly manner.

(Example) Below are 711 fruits of the present invention! i 1541 will be explained in detail with reference to the drawings. As shown in FIG. 1, the optical fiber surplus length holding sheet 1 of this embodiment has a sheet main body 2 made of polyester or the like, and the sheet main body 2 has a pair of holding pieces 3.
The holding piece forming slits 5 and 6 forming the holding piece 4 are provided facing each other in opposite directions.

A round hole 7 is provided at the end of the slit 5, 6 to facilitate the rising of the holding pieces 3, 4 and to prevent the slit 5, 6 from expanding.
8 are formed respectively. l1f on one holding piece 4
ll 1B A fully bent connecting portion holder 9 is fixed on the seat body 2 with adhesive or a grommet.

In such an optical fiber surplus length holding sheet 1, the surplus length portion 10A of the optical fiber core 10 or the like is formed into a loop shape as shown in FIG. 2, and is held by both the holding pieces 3.4 and the sheet body 2.

In addition, if the fiber connecting portion 11 is present, it is supported by the connecting portion holder 9.

In this way, the extra length portion 10Δ is stored in the extra length storage tool while being held by the optical fiber extra length holding sheet 1. By holding the extra length part 10A with the sheet 1 in this way and storing it in the extra length storage tool, it becomes easier to insert the extra length part into the extra length storage tool, and it also prevents the extra length part from coming apart in the extra length storage tool. This can be prevented, and the extra length storage device can be taken out in an orderly manner.

The shape of the holding piece 3.4 is not limited to the rectangular shape shown in the figure, but may be any other suitable shape, such as a ``■'' shape.

Furthermore, the connection portion holder 9 may be omitted.

(Effects of the Invention) As explained above, the optical fiber surplus length holding sheet according to the present invention is provided with holding piece forming slits forming a pair of holding pieces in the sheet body, and holds a loop-shaped optical fiber core wire, etc. Since the extra length is held by both holding pieces and the seat body, the extra length can be easily stored in the extra length storage tool, and the extra length can be kept loose inside the extra length storage tool. This can be prevented, and the extra length can be taken out from the extra length storage device in an orderly manner. Further, since this extra length holding sheet can be formed by simply punching out the sheet, it is available at a very low cost, is not bulky, and is very convenient to handle.
