Description

  The present invention relates to a structure of a splice box configured to store a fusion tray for connecting an optical communication line used for optical communication and a member for storing and guiding the optical communication line.

As shown in FIG. 6, members such as a fusion tray 31 and an optical adapter 32, and members such as a wire saddle 33, a cable clamp 34, and a tension member holder 35 for storing an extra length of an optical communication line are provided on a base 36. The base 36 was attached to the main body 37 of the splice box. For example, the fusing tray 31 is disposed at a substantially central portion of the base 36, and the tension member press 35 is attached in the vicinity thereof. A wire saddle 33 is provided in a place where it does not interfere with the fusing tray 31 and the tension member presser 35, and an extra length such as an optical cord is wound around and stored therein.

  However, the arrangement of the devices as described above has a drawback that the tension member presser itself is an obstacle and it is difficult to guide the core wire to the fusion tray. Further, there is a possibility that the tension member press may interfere with the storage of the extra length. The extra length storage space must be provided avoiding the tension member press, and the cabinet size may increase depending on the arrangement. It has been necessary to cut the length of the tension member protruding from the tension member presser so that the tip does not protrude, or to cure the tip with tape or the like.

Therefore, the present invention aims to improve the workability of the splice box, and its structure is such that the tension member press is fixed to the base of the splice box, the insertion port for allowing the tension member to reach the tension member press, and the tension the members holding fixed by coating the base provided with the insertion hole for performing the screwing operation insert the fixing screw for fixing to the base, fused tray on the base, in that a member for optical communication lines Features.

The structure of the splice box according to the present invention is such that the tension member press is fixed to the base of the splice box, an insertion port for allowing the tension member to reach the tension member press, and the tension member press to fix the tension member press to the base. coated with base provided with the insertion hole for performing the screwing operation insert the screws to secure, fused tray on the base, for placing the members for optical communication line, not obstruct the tension member holding the wiring The workability can be improved. Since the tension member press is not on the base, the space on the base can be used as a wiring space, the size of the splice box can be reduced, the mounting location is not limited, and the manufacturing cost can be reduced. Since the tension member presser is stored under the base, even if the tension member is long, it is covered with the base, so that the treatment such as curing is not required and the workability is improved.

  The structure of the splice box according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The splice box has a space for arranging devices such as a fusion tray 1 for connecting an optical communication line used for optical communication, an optical adapter (not shown), and storing an extra length of the optical communication line. Provided. In addition to the equipment stored in the splice box, the cable clamp (not shown) that fixes the cable inserted into the splice box, the tension member holder 2 that fixes the tension member extending from the cable, and the extra length of the optical fiber There is a wire saddle 3 for winding. The splice box constitutes a main body from a base 4 on which equipment is arranged and a door (not shown) that covers the front surface of the base 4. The devices are fixed to the base 5 by screwing or the like, and the base 5 is attached to the base 4 and stored.

  The base 4 is provided with a fixing hole 6 for fixing the base 5 and an attachment hole 7 for attaching the tension member presser 2. The tension member presser 2 is provided with an insertion hole 8 at a position facing the attachment hole 7, and has an insertion port 9 and an extraction port 10 through which the tension member is passed. A screw 11 is provided in the vicinity of the insertion port 9, and the tension member is fixed by tightening the screw 11. The tension member presser 2 has the insertion hole 8 opposed to the mounting hole 7, and a screw 12 is inserted into each of them and fixed to the tightening base 5.

  An insertion port 13 for drawing a cable is provided on the side surface of the base 5 on which the device is arranged. The base 5 is provided with a fusing tray 1, a wire saddle 3, and the like, and fixed to the base 4 while covering the tension member presser 2. An insertion hole 14 is provided on the upper surface of the base 5 at a position facing the insertion hole 8 of the tension member presser 2. The insertion hole 14 is larger than the head diameter of the screw 11 to be inserted, and is sized so that the screw 11 can be passed from the surface.

  The cable is fixed to the base 4 by a cable clamp, and the tension member is inserted into the base 5 through the hole 13 on the side surface of the base 5 and inserted into the outlet 10 from the insertion port 9 of the tension member presser 2. At the insertion port 9, a tool such as a screwdriver is inserted into the insertion hole 14 of the base 5 and a screw is tightened to fix the tension member.

  The screw for fixing the tension member has a length that can be tightened even if the diameter of the tension member is small. The height of the base is such that the screw head does not protrude from the base even if the diameter of the tension member is large.

  Since the tension member was conventionally fixed on the base, it was necessary to cure the tip of the tension member in order to safely protect it, but in the present invention, the tip of the tension member is stored under the base. Since it is not touched, curing is unnecessary and workability is improved.
