Abstract

<P>PROBLEM TO BE SOLVED: To provide an extra length housing structure capable of housing an extra length of an optical cord with a simple structure and in a manner saving a space. <P>SOLUTION: The extra length housing structure is provided with a first guide 3a for winding an extra length of an optical cord 2 on a tray 1 and, under the first guide 3a, with a second guide 3b in which a space is secured for the extra length of the optical cord 2 to make at least one circle around it. The structure is characterized in that it makes housing in a small space possible for much extra length of the optical cord 2 and that it facilitates operation of housing the extra length. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a surplus length storage structure for storing an optical communication device on a tray and storing a surplus length of an optical cord for wiring the optical communication device.

As shown in FIG. 5, optical communication devices such as a fusion tray 31 to which an optical cord is connected, an optical adapter 32, a cable clamp 33 for supporting and fixing an optical cable, and a tension member press 34 are arranged on a panel 35. Conventionally, a wire saddle 36 that winds the extra length of the optical cord is provided in the vicinity of the optical adapter 32. Since the optical cord cannot be used because it is bent, the minimum required diameter of the wire saddle 36 and the distance required for connection from the end of the extra length to the optical adapter 32 are also determined. The installed wire saddle 36 was wound and stored while adjusting the extra length.

  However, in the above-mentioned extra length storage structure, the work of winding the wire saddle while adjusting the extra length is complicated, and if it is not enough even around the wire saddle, it must be stored around the wire saddle. It was. Since it cannot be bent due to the characteristics of the optical cord, a large space for storing the extra length is inevitably required.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an extra length storage structure that can store an extra length of an optical cord in a space-saving manner with a simple structure. The structure is a first for winding an extra length of an optical cord around a tray. A guide and a second guide that secures a space for at least one round of the extra length of the optical cord are provided below the first guide.

  The surplus length storage structure according to the present invention has a first guide for winding the surplus length of the optical cord on the tray, and a space for at least one round of the surplus length of the optical cord at the bottom of the first guide. Since the second guide is provided, the surplus length can be stored with a margin in the first guide due to the surplus length of one turn wound around the second guide. In addition, since the distance between the optical adapter and the guide can be secured and the length of the insertion tool to the optical adapter can be taken, the length of the extra length can be easily adjusted.

  A surplus length storage structure according to the present invention will be described with reference to the accompanying drawings of FIGS.

  An optical communication device is arranged on the tray 1, and the optical communication device is wired by the optical cord 2, and a guide 3 for storing the extra length of the optical cord 2 is provided in the optical communication device storage cabinet. A connection tool 5 for connecting to the optical adapter 4 is attached to the extra length portion of the optical cord 2. Since the portion of the connector 5 is not bent, the extra length is stored at a position separated from the optical adapter 4 by the distance of the connector 5 at the tip of the optical cord 2.

  Since the optical cord 2 cannot be used by being bent due to its characteristics, the guide 3 needs to have a diameter that allows the extra length to be wound without being bent.

  In order to store the extra length of the optical cord 2, a first guide 3a is provided. At the bottom of the first guide 3a, the second guide 3b having the diameter of the first guide 3a is provided not at the same center as the first guide 3a but at a position shifted in a direction away from the optical adapter 4. . The second guide 3b and the wall surface of the tray 1 need only have a gap that allows the optical cord 2 to make at least one round.

  The extra length of the optical cord 2 connected to the optical adapter 4 causes the second guide 3b to make one turn, and the second guide 3a is wound around the first guide 3a. The first guide 3a can be wound as much as the second guide 3b is wound, and as a whole, the amount of extra storage can be increased. The guide 3 has a minimum diameter so that the optical cord 2 is not bent. When the guides 3 are provided in two stages and the centers are the same, a large space is required between the tray 1 and the guides 3 in order to store the extra length. In the present invention, in order to save space, the second guide 3b is set only to make one turn of the optical cord 2, and the space between the tray 1 and the second guide 3b is also minimized. The space on the limited tray 1 can be utilized to the maximum.

  In order to store the extra length of the optical cord, the guide is provided in two steps, upper and lower, so that the optical adapter is attached to the lower position as much as possible along with the lower second guide. It is possible to store the extra length of the optical cord that has not been completed, and to provide a space-saving extra length storage structure.
