[0002] An optical cable distribution box is a device used in an optical fiber communication network, mainly for branching, connecting, and managing optical cables. It is usually installed indoors or outdoors to protect optical fiber connectors, prevent damage to optical fibers from the external environment, and facilitate maintenance and management.

[0003] Currently, there are many types of optical cable distribution boxes on the market. For example, a fiber optic rapid deployment system with a publication number of CN107340576B is disclosed on the Chinese Patent Network. This fiber optic rapid deployment system can be used for the distribution of optical cables in corridors, but there are some defects and deficiencies to be improved: (1) Some existing optical cable distribution boxes only consider horizontal cabling (cabling in and out from left and right), but do not consider vertical cabling. There will be an optical cable on each floor, which does not play a role in saving optical cables; (2) After some existing optical cable distribution boxes are connected to the distribution box and connected to the adapter, there is a lack of effective fixing measures, making the cable easy to fall off from the adapter, resulting in the optical cable not working properly; (3) Due to the structural design of some existing optical cable distribution boxes, after the optical cable is connected to the distribution box, due to the large number, the cables tend to be concentrated together, making it easy for the cables to be entangled with each other.

[0029] Please refer to Figures 1-5 As shown, a corridor-type optical cable distribution box of the present utility model includes a box body 1 and a box cover 2. The box body 1 and the box cover 2 are connected by a hinge. The top and bottom of the box body 1 are respectively provided with an optical cable inlet 3 and an optical cable outlet 4. The top and bottom of the box body 1 are respectively provided with a plurality of first pigtail cable outlets 5 and a plurality of second pigtail cable outlets 6. A fiber optic splice tray 7 and a connector panel 8 are respectively installed in the box body 1. The fiber optic splice tray 7 can provide a fixed position for the fiber optic fusion point. The connector panel 8 is used to install adapters. Through the adapters, fiber optic connectors can be placed and redundant optical fibers can be stored. The optical cable can enter the box body 1 from the optical cable inlet 3 and be led out from the optical cable outlet 4. When the optical cable enters the box body 1, it can be divided into multiple strands of optical fiber cables. These multiple strands of optical fiber cables can be respectively connected to the adapters and are respectively connected to each user's home through the first pigtail cable outlets 5 and a plurality of second pigtail cable outlets 6. By adopting the method of the optical cable entering and exiting from top and bottom, the optical cable resources can be maximally utilized, and it is not necessary to lay an optical cable for each floor, effectively solving the pain point that the left and right cable inlets and outlets cannot be bent through the entire floor. A pair of wire fixing components and a pair of limiting components are respectively arranged in the box body 1;

[0030] The wire fixing component includes a wire fixing seat 9. On both sides of the wire fixing seat 9 close to the connector panel 8, a plurality of wire grooves 10 are opened on the top surface. A wire pressing plate 11 is installed on the top of the wire fixing seat 9. Threaded holes 12 are opened at both ends of the wire pressing plate 11. A bolt 13 matching with the threaded hole 12 is threadedly connected in the threaded hole 12. A pair of threaded grooves 14 matching with the bolt 13 are opened on the surface of the wire fixing seat 9. When the divided optical fiber cables are connected to the adapters, each cable can be aligned and attached to the corresponding wire groove 10. At this time, by tightening the bolt 13 in the threaded hole 12, the wire pressing plate 11 can be tightly pressed on the wire fixing seat 9 to fix the cables in the wire grooves 10, thereby effectively preventing the cables from falling off the adapters;

[0031] The limiting component includes a limiting seat 15, which is respectively close to the first skin cable outlet 5 and the second skin cable outlet 6. A plurality of lower limiting grooves 16 are formed on the top surface thereof, and guide rods 17 are fixedly connected to both sides of the top of the limiting seat 15. A convex block 18 is fixedly connected to the top end of the guide rod 17. A limiting plate 19 is installed on the top of the limiting seat 15. A pull ring 20 is fixedly connected to the top of the limiting plate 19, and guide holes 21 are formed at both ends of the limiting plate 19. Each guide rod 17 passes through the corresponding guide hole 21, and a spring 22 is wound around its rod body. The top end and the bottom end of the spring 22 are respectively fixedly connected to the bottom of the convex block 18 and the top of the limiting plate 19. A plurality of upper limiting grooves 23 are formed on the bottom surface of the limiting plate 19. When the optical fiber cable after being connected to the adapter is led out from the first skin cable outlet 5 and the second skin cable outlet 6, each cable can be aligned and attached to the corresponding lower limiting groove 16. At this time, the limiting plate 19 can be driven to move upward through the pull ring 20. After the cable passes through the lower limiting groove 16, the pull ring 20 is released, and the limiting plate 19 will tightly abut against the top of the limiting seat 15 under the elastic reset action of the spring 22. At this time, the top of the cable can be attached to the corresponding upper limiting groove 23. The multiple cables can be separated and limited through the combined action of the upper limiting groove 23 and the lower limiting groove 16, thus effectively avoiding the entanglement between the cables.

[0032] Among them, the diameters of the optical cable inlet 3 and the optical cable outlet 4 are equal, and the centers of the optical cable inlet 3 and the optical cable outlet 4 are located on the same straight line. The optical cable can enter the box body 1 from the optical cable inlet 3 and be led out through the optical cable outlet 4. Through a small number of such optical cable distribution boxes, a single optical cable can be branched and respectively connected to multiple user homes in the corridor, thus realizing the maximum utilization of optical cable resources without laying an optical cable on each floor.

[0033] Among them, the numbers of the first skin cable outlets 5 and the second skin cable outlets 6 are the same, the diameters are equal, and the centers of each first skin cable outlet 5 and the centers of each second skin cable outlet 6 correspond to each other one by one. The cable can pass straight through each first skin cable outlet 5 and the second skin cable outlet 6 to effectively prevent the cable from bending.

[0034] Among them, the cable fixing groove 10 is semi-circular, its diameter is equal to the diameters of the first skin cable outlet 5 and the second skin cable outlet 6, and the centers of each cable fixing groove 10 correspond to the centers of each first skin cable outlet 5 and each second skin cable outlet 6 one by one. The cable after being connected to the adapter can pass straight through and be attached to the corresponding cable fixing groove 10, effectively avoiding the cable from bending.

[0035] Among them, the upper limit groove 23 and the lower limit groove 16 are both semi-circular, with the same number, equal diameters, and the centers of each upper limit groove 23 corresponding one by one to the centers of each lower limit groove 16. The top and bottom of the cable can be simultaneously attached to the upper limit groove 23 and the lower limit groove 16, and the cable can move within a certain range along the upper limit groove 23 and the lower limit groove 16 to adjust the stretching length of the cable as needed.

[0036] Among them, a layer of rubber pad is provided on the surface of the groove walls of each upper limit groove 23 and the lower limit groove 16. The surface of the rubber pad is engraved with diamond-shaped anti-slip patterns. The rubber pad is fixed in the upper limit groove 23 and the lower limit groove 16 by means of glue, etc., which can play a certain role in buffering and anti-wear, so as to avoid direct contact between the cable and the groove walls of the upper limit groove 23 and the lower limit groove 16 and cause wear. And when stretching the cable, the anti-slip patterns on the surface of the rubber pad can increase the friction between the cable and the upper limit groove 23 and the lower limit groove 16, so as to provide a certain resistance when stretching the cable, thereby preventing the cable from being stretched too long at one time.

[0037] The circuits, electronic components, and chip modules involved in the present utility model are all prior arts, which can be fully realized by those skilled in the art without further elaboration. The content protected by the present utility model does not involve improvements to software and methods either.

[0038] The standard parts used in the application documents can be purchased from the market. All the components in this application document can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art. The electrical components described in this article are all electrically connected to the external main controller and the 220V mains power supply, and the main controller can be a conventional known device such as the LED lamp body for control.

[0039] The working principle of the present utility model is:

[0040] When the utility model is in use, the optical cable can enter the box body 1 from the optical cable inlet 3 and be led out from the optical cable outlet 4. After the optical cable enters the box body 1, it can be split into multiple optical fiber cables. These multiple optical fiber cables can be respectively connected to the adapters and access each user's home through the first pigtail cable outlet 5 and several second pigtail cable outlets 6. By adopting the way of the optical cable entering and leaving from the top and bottom, the optical cable resources can be maximally utilized. There is no need to lay an optical cable on each floor, effectively solving the pain point that the left and right cable outlets cannot bend through the whole floor. After the split optical fiber cables are connected to the adapters, each cable can be aligned and attached to the corresponding wire fixing groove 10. At this time, by tightening the bolt 13 in the threaded hole 12, the pressing plate 11 can be tightly pressed on the wire fixing seat 9 to fix the cable in the wire fixing groove 10, so as to effectively prevent the cable from falling off the adapter. When the optical fiber cables connected to the adapters are led out from the first pigtail cable outlet 5 and the second pigtail cable outlet 6, each cable can be aligned and attached to the corresponding lower limiting groove 16. At this time, the limiting plate 19 can be driven to move upward by the pull ring 20. After the cable passes through the lower limiting groove 16, release the pull ring 20, and the limiting plate 19 will tightly abut against the top of the limiting seat 15 under the elastic reset action of the spring 22. At this time, the top of the cable can be attached to the corresponding upper limiting groove 23. The upper limiting groove 23 and the lower limiting groove 16 can jointly separate and limit multiple cables, effectively avoiding winding between the cables.
