Description

  The present invention relates to a splice box for storing an optical communication device and an optical fiber for wiring the optical communication device.

Conventionally, as described in Japanese Patent Application Laid-Open No. 2001-188135, the splice box is connected to an optical wiring device such as an optical adapter, a tension member presser, an extra length storage unit, a cable clamp, and a fusion tray on the base. And placed on a plane.

  However, in the splice box in the above background art, since the optical wiring device is arranged on a plane, a space for arranging each optical communication device is required, and a lot of space is required. Therefore, the entire splice box is enlarged. It corresponded. The installation location of the splice box was limited, and the manufacturing cost of the splice box was also borne.

  Therefore, the present invention has an object to provide a splicing box that saves space and has good workability. The structure of the splicing box includes an optical adapter, a tension member presser, an extra optical fiber length storage unit, a cable clamp, etc. A fusion tray for fusing optical fibers is attached to a cover that can be opened and closed by a pivoting operation with a hinge structure on the upper surface of the optical wiring device provided on the base. .

  According to the present invention, the base of the splice box includes an optical adapter, a tension member presser, an optical fiber extra length storage unit, a cable clamp and other optical wiring devices, and a fusion tray for fusing the optical fiber is provided on the base. Because it is attached to a cover that can be opened and closed by a pivoting operation with a hinge structure on the upper surface of the optical wiring equipment, the inside of the splice box can be divided into multiple layers and space saving of the splice box can be achieved. The place is not limited, and the manufacturing cost of the splice box can be reduced. Since the cover for attaching the fusing tray can be rotated, the load on the optical fiber can be reduced, and the wiring workability can be improved.

  An embodiment of a splice box according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The splice box 1 stores optical wiring equipment such as an optical adapter 3, a tension member presser 4, an extra optical fiber storage section 5, a cable clamp 6, and a fusion tray 7 for fusing optical fibers on a base 2. The These optical fibers (not shown) for connecting the optical communication devices cannot be accommodated because they are folded due to their characteristics, so that the optical wiring devices must be arranged with a margin.

  In the splice box 1 according to the present invention, an optical adapter 3, a tension member presser 4, an extra optical fiber length storage unit 5, and a cable clamp 6 are arranged on the direct base 2. The cover 8 that covers the optical wiring device arranged on the base 2 is attached so as to be opened and closed by rotating the hinge structure. The fusing tray 7 is attached to the upper surface of the cover 8, and optical wiring devices are arranged in multiple layers.

  The attachment structure of the cover 8 will be described with reference to FIG. A hinge mounting component 9 is fixed to the base 2. A long hole 10 is provided in the hinge attachment component 9, and a rotation hole 11 is extended at the upper end of the long hole 10. The cover 8 is attached by the hinge pin 12 at the portion of the rotation hole 11. The cover 8 can be opened and closed by a pivoting operation, and the work is performed by opening the cover 8 when equipment is attached to the base 2 or maintenance work is performed. When the cover 8 is opened, the hinge portion of the cover 8 can be moved to the long hole 10, and the long hole 10 can be moved in the direction of the base 2 by a sliding operation. The cover 8 is moved in the direction of the base 2, the cover 8 is caught in the long hole 10, and the cover 8 can be held in an open state in the vertical direction.

  As shown in FIG. 4, the splice box 13 according to the present invention can be additionally provided with optical wiring devices such as a fusion tray 14 and an optical adapter 15. The fusing tray 14 and the optical adapter 15 are stacked in multiple stages in the depth direction. Since the fusion tray 14 and the optical adapter 15 are added to the previously vacant part, the number of fusion points can be increased and high-density storage can be achieved without increasing the splice box 13.

  The optical wiring device accommodated in the splice box can be disposed in a space-saving manner, and can be provided at a low cost without limiting the installation location of the splice box.

It is explanatory drawing which shows the Example of the splice box which concerns on this invention. It is A-A 'sectional drawing in FIG. It is an enlarged view of the hinge structure of the cover of the splice box according to the present invention. It is explanatory drawing which shows the state which increased the wiring apparatus of the splice box which concerns on this invention.
