Abstract

<P>PROBLEM TO BE SOLVED: To provide an extra length cord housing part for an optical junction box used in an optical junction box for connecting an optical cord with which the width of the optical junction box can be reduced. <P>SOLUTION: At least three laterally long winding members 5 or more are arranged on a plate 4 in a row, and many extra length cord winding block parts 6 are formed with two optically selected winding blocks 5, 5 as a pair. Thus, the spacing in the width direction is secured by the laterally long part of a winding member 5, and the spacing in the depth direction is secured by an interval between two winding members 5, 5 to obtain many extra length cord winding block parts 6 for circularly winding an optical cord 102, to make the extra length cord housing part narrower and to make the width of the optical junction box smaller. <P>COPYRIGHT: (C)2004,JPO

However, in this conventional device, since the extra length of the optical cord 102 is wound around the winding member 103 at one place, the winding diameter is large. Therefore, it is necessary to increase the extra length of the optical cord 102 by that amount. Further, depending on the position of the adapter 101, the optical cord 102 from the winding member 103 is drawn into the adapter 101, so that the adapter 101 and the winding member 103 must be spaced apart from each other in order to ensure a minimum bend R that does not cause a light transmission loss. Therefore, the width of the optical connection box cannot be reduced. Furthermore, a large number of optical cords 10
Since the extra length of 2 is wound together, the adapter 1
It was impossible to identify how the optical cord 102 connected to 01 was wound around the winding member 103.

Therefore, the winding size of the extra length portion may be reduced so that the extra length portion may be short.
Since the cord can be pulled in between the cord extra length winding block part 6 and the adapter 2 which are adjacent to each other, a constant bend R can be secured even if the distance between the cord extra length winding block part 6 and the adapter 2 is short. The width of the optical junction box can be reduced. Further, since the respective optical cords 102 wound around the large number of extra length winding block portions 6 are to be connected to the adjacent adapters 2, there is a correspondence relationship between the extra length optical cords 102 and the adapter 2. Since it is clear, maintenance and inspection work is easy.

If a cord winding locus diameter expansion restricting portion 5a having a concave curved surface is formed on the outer surface of the horizontally long portion 51 of the winding member 5, the cord formed adjacent to the winding member 5 will be described. It is possible to prevent the optical cord 102 wound around the extra length winding block portion 6 from spreading and limit the winding size to a certain size or less to prevent the optical cord 102 from protruding to the adapter 2 side. Further, by forming the cord winding locus diameter reduction regulating portions 5b at both ends of the winding member 5, the optical cord 102 wound around the extra cord length winding block portion 6 has a minimum bend R without light transmission loss. It may not be that:

Further, a wall for restricting the diameter of the cord winding locus is provided on the peripheral edge of the plate 4 on which the optical cord entry / exit side, that is, the side facing the adapter 2, is excluded from the plate 4 in which the horizontally long winding members 5 are arranged in a row. If the plate portion 41 is set upright, the plate 4
The extension of the optical cords wound on the extra cord length winding block portions 6 formed at both ends of the optical cord 102 is restricted, and the optical cords 102 wound around the extra cord length winding block portions 6 are restricted. It is possible to control the expansion of the side opposite to the adapter side.

As described above, in the extra cord length storing portion of the optical connection box of the present invention, at least three winding members are arranged in a row on the plate, and two arbitrarily selected winding members are arranged. Since a large number of cord extra length winding block portions are formed by using one winding member as a set, the winding size of the extra length portion can be reduced and the extra length can be shortened. Further, since the winding portion can be pulled into the adapter between the adjacent cord extra length winding block portion and the adapter, even if the distance between the extra cord length winding block portion and the adapter is shortened, a constant bending R
Since the width of the optical junction box can be reduced, the optical cord in the extra length can be easily identified and the correspondence with the adapter is clear, which facilitates maintenance and inspection work. Therefore, the present invention solves the problem of the cord extra length storage portion of the conventional optical junction box, and is a great advantage for the industry.
