Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 5, an embodiment of the present specification provides a drawable optical cable termination box for a cabinet, including a box body 1 and a tray assembly 2, where the box body 1 is fixed in the cabinet through mounting lugs 3 arranged on both sides of the box body, the tray assembly 2 is slidably arranged in the box body 1 through guide rail assemblies 4 on both sides of the tray assembly, a door panel 11 capable of opening and closing is arranged at a front end of the box body 1, optical cable fiber outlets 12 are arranged on both sides of a front end of the box body 1, an optical cable inlet 13 is arranged at a rear end of the box body 1, the tray assembly 2 includes a tray 21, and an adapter mounting plate 22 and one or more fusion splicing plates 23 detachably arranged on the tray 21, a plurality of mounting holes for mounting different adapters are arranged on the adapter mounting plate 22, and a fixing baffle 24 is further arranged between the fusion splicing plates 23 and the adapter mounting plate 22.

Note that, in fig. 4, two fusion plates 23 are stacked up and down, and in practice, any number of fusion plates 23 may be used as needed. In addition, the door plate 11 may be mounted on the case 1 by a hinge. The adapter mounting plate 22 can be mounted on the tray 21 by bolts, and the tray 21 is provided with corresponding mounting holes.

A plurality of wire passing coils 25 are arranged between the two optical cable outlet ports 12 and on the tray 21. The coil 25 is arranged, so that the optical cable can be conveniently arranged and wired. A plurality of hollow holes 26 are arranged between the adapter mounting plate 22 and the wire passing coil 25 and on the tray 21. On the one hand, the weight and material costs of the tray 21 can be reduced, and on the other hand, it is convenient to handle mounting adapters or wiring lines.

The rear end of the box body 1 is also provided with an optical cable stripping protection device 5.
