の向上とが図れる。According to the cabinet for storing a cable connecting portion of the present invention, a connecting portion of a metal cable can be easily stored, and a plurality of trays for protecting and storing an extra connection portion of a branch optical fiber are separated from each other. It is stored in the storage frame so that it can be inserted and removed, so you can open or remove any core tray and check, check, and adjust the connection work and the connection status of the core drop branched from the tape core. Can be performed very easily and safely. In addition, the tape core storage unit and the drop core storage unit have a high-density storage structure with multiple layers of trays in multiple connection units, and each core tray holds and fixes the connector of the core connection unit. In addition, since the excess core length can be handled and stored after securing the radius of curvature, the excess core length can be accommodated with a certain degree of freedom in absorption, and the transmission characteristics are not adversely affected. Moreover, even if the core tray is returned to the original position after the core connection work, the optical fiber core does not become slack, and the core does not excessively bend and does not have an arc-shaped portion having a small radius of curvature. It can be stored for safe protection. Furthermore, the drop optical cables can be individually stored in the core tray, and inserted into the tray holder to organize them with the adjacent core tray. It can be exposed separately, making it easy to connect and update and expand core trays, improve safety by simple core identification and use of hard trays, and take out, connect and re-store any cores. The handling characteristics can be improved.

2 is provided so that the support line of the drop optical cable drawn out from 2 can be fixed by the drop optical cable support line holding tool 61. As shown in FIG. 7, as the drop optical cable support wire gripping tool 61, in the case of a vertical (RD) type, a partition frame 63 and a plurality of screws are mounted on a gate-shaped support piece 62 having a mounting leg piece 65. The support wire of the drop optical cable is fixed with a screw so that even if stress is applied to the drop optical cable, the drop optical cable is received by the gripper 61 and does not adversely affect the core wire tray 32. In this case, the support piece 62 has a split connection structure (FIG. 1).
In addition, it is possible to easily pull up a cable from a pipeline in an additional construction (SO construction) or the like. Also, in the vertical (RD) type, since the core wire tray is fixed in the vertical direction, even if the tray is pulled out from the tray holder,
The stress of the drop optical cable is hardly applied to the tray.

うにすることができる。The drop optical cable support wire gripping tool 61 shown in FIG. 8 is of a horizontal type (OD) type. A plurality of support pieces 62 are arranged in parallel with a step, and a support wire e of the drop optical cable is screwed with a screw 64. The drop optical cable f is routed through the lower surface of the partition frame 63. The horizontal (OD) type is a tray holder for drop optical cables coming out of the core tray to change the route in a right angle direction. When the tray is pulled out from the tray, a load is applied to the tray and the tray is easily deformed. Therefore, in this OD type, a stress adjusting portion 66 shown in FIG. 6
Care has been taken to prevent the tray from being deformed by the movement of the tray 7. The stress adjusting section 66 is provided with a comb-shaped sliding piece 67, which is screwed to the guide groove 68 so as to be freely movable. When the core wire tray is pulled out and worked, the sliding piece 67 is drawn out and used. I do. For example, if the drop optical cable comes off from the sliding piece 67 when pulling out the core tray, a load (tension) is applied to the drop tension member (DTM) gripping of the core tray, and the core tray may be deformed, whitened, or adversely affected. , So that the disadvantage is eliminated. Further, since the sliding piece 67 is provided, it is possible to prevent abnormal stress from being applied to the core tray for storing the drop optical cable.

体を的確に保持できて安全性も高められる。According to the present invention, there is provided a metal cable connecting portion of a metal cable, an optical cable connecting portion of an optical cable, and a tape cable storing portion for storing a cable extra length extending from the optical cable connecting portion.
In a cabinet provided with a core-connection extra-length storage portion branched from the optical cable, the metal core connection portion introduced into the cabinet main body, and a tape-core storage portion and a core-connection extra-length storage portion of the optical cable. And a cable holding portion for holding a tension member of the optical cable, and the tape core storage portion is provided with a plurality of partitions at intervals. And a soft sheet storage tray with an openable and closable outer lid on the partition plate is slidably provided. The core wire tray is inserted into and removed from the tray holder provided in the cabinet body. By being fitted freely, the core tray can be easily engaged and disengaged, and can be easily wired using both metal and optical cables. When pulling down the cable, the multiple fiber trays can be easily connected or switched, or branch connection work and re-storage work can be carried out easily without adversely affecting the transmission characteristics of the optical cable from the cable lead-in / out section. The multi-layered high-density storage structure makes it easy to store and organize the tape cores, increase and decrease the number of cores easily, and easily add and remove them. Therefore, after the splicing operation, any fiber tray can be opened and the stored optical fiber can be quickly pulled down, the spliced core can be easily identified and the connection can be readjusted and repaired easily. Workability is greatly improved, and each core tray can be stacked as many as necessary, and the entire storage tray stacked in multiple stages can be accurately retained and safety increased. It is.
