Description

Technical Field

[0001] This utility model relates to the field of fiber optic terminal box technology, specifically a pull-out fiber optic terminal box. Background Technology

[0002] A pull-out fiber optic terminal box, also known as a drawer-type fiber optic patch panel or tray-type terminal box, is a rack-mounted or wall-mounted device. Its interior contains one or more fiber optic splice trays / patch panels that can be pulled out and pushed in like drawers. It includes a pull-out tray, splice area, splice tray adapter mounting base, fiber optic exit / entry points, adapters, etc.

[0003] Existing pull-out fiber optic terminal boxes suffer from insufficient stability and inconvenient disassembly when installing fiber optic adapters. They require external tools such as bolts and screws for fixing during installation, which is not conducive to rapid installation and disassembly when installing large numbers of fiber optic connections.

[0004] To address this issue, this technical solution designs a pull-out fiber optic terminal box. Utility Model Content

[0005] The purpose of this invention is to provide a pull-out fiber optic terminal box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The pull-out fiber optic terminal box includes a pull-out base and a pull-out tray. The pull-out tray is slidably disposed inside the pull-out base to achieve the pull-out design. A fiber coiling platform is provided on one side of the top of the pull-out tray, on which multiple fiber coiling columns are evenly installed for coiling and storing optical fibers. At the same time, multiple baffles are installed at equal intervals at the front end of the pull-out tray, and fiber optic adapter mounting slots are provided between adjacent baffles. The fiber optic adapter mounting slots are elastically engaged with multiple sets of longitudinally stacked adapter mounting seats. Multiple optical fiber adapters are longitudinally inserted along the length direction on the inner side of the top of the adapter mounting seats. The optical fibers at the ends of the optical fiber adapters extend to the fiber coiling platform for coiling and storage. In other words, by utilizing the elastic engagement between multiple sets of adapter mounting seats and the fiber optic adapter mounting slots, as well as the optical fiber adapters installed by insertion on the top of the adapter mounting seats, the terminal box can easily install and remove optical fibers, and can also be used for batch installation and application of optical fiber adapters.

[0008] The adapter mounting base includes a base plate with end elastic clamping plates installed at both ends of the top of the base plate. The end of the end elastic clamping plate away from the center of the base plate is set with an L-shaped structure, which elastically contacts the end of the baffle on both sides of the fiber optic adapter mounting base slot, thereby elastically positioning the base plate in the fiber optic adapter mounting base slot. Multiple sets of parallel and inclined staggered slot plates are installed at equal intervals on the top of the base plate between the two end elastic clamping plates. The front and rear ends of the staggered slot plates are provided with side slots with opposite openings. Adapter mounting slots are provided between adjacent staggered slot plates and between the staggered slot plates and the end elastic clamping plates. The fiber optic adapter to be installed is inserted into the adapter mounting slot for positioning.

[0009] The end elastic plate also has a side slot on the side facing the misaligned slot plate. At the same time, a T-shaped bottom plate is installed on the front side inside the adapter mounting slot. The bottom slot and the side slot are respectively provided with bottom slots and side blocks installed at the corresponding optical adapters. By using the insertion of the side block and the side slot, and the insertion of the bottom slot and the bottom plate, a triangular insertion positioning is formed, thereby realizing the quick installation and separation of the optical adapter.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the elastic snap-fit ​​structure between the adapter mounting base and the mounting bayonet, and the triangular plug-in positioning structure between the optical adapter and the mounting slot, the rapid installation and disassembly of the optical fiber adapter is realized. The whole process does not require any external tools, which greatly improves the efficiency of large-scale optical fiber installation and maintenance.

[0011] By using a staggered slot plate to form the adapter mounting slot and using the triangular plug principle for fixing, the connection stability and reliability of the optical adapter in the mounting base are significantly enhanced, preventing it from loosening or falling off during use.

[0012] By using a vertically stacked design for multiple adapter mounting bases and pressing the lower layer with the upper layer, the overall structural stability and compactness are further enhanced, saving space and increasing the port density of the terminal box. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6The pull-out fiber optic terminal box includes a pull-out base 10 and a pull-out tray 11. The pull-out tray 11 is slidably disposed inside the pull-out base 10 to realize the pull-out design of the pull-out tray 11. A fiber coiling platform 12 is provided on one side of the top of the pull-out tray 11. Multiple fiber coiling columns 13 are evenly installed on the fiber coiling platform 12 for storing and coiling optical fibers. At the same time, multiple baffles 17 are evenly spaced at the front end of the pull-out tray 11. Fiber optic adapter mounting slots are provided between adjacent baffles 17. The fiber optic adapter mounting slots elastically engage multiple sets of vertical... The adapter mounting bases 18 are stacked and distributed. Multiple optical fiber adapters 23 are longitudinally inserted into the inner top of the adapter mounting bases 18 along the length direction. The optical fiber at the end of the optical fiber adapter 23 extends to the fiber coiling table 12 for coiling and storage. By utilizing the elastic snap-fit ​​between the multiple sets of adapter mounting bases 18 and the optical fiber adapter mounting base slots, as well as the optical fiber adapters 23 installed in the top of the adapter mounting bases 18, the terminal box can be conveniently installed and removed from the optical fiber. At the same time, the optical fiber adapters 23 can be installed and applied in batches.

[0025] The adapter mounting base 18 includes a base plate 26. End elastic clamping plates 21 are installed at both ends of the top of the base plate 26. The end of the end elastic clamping plate 21 away from the center of the base plate 26 is set with an L-shaped structure, which elastically contacts the ends of the baffles 17 on both sides of the fiber optic adapter mounting base slot, thereby elastically positioning the base plate 26 in the fiber optic adapter mounting base slot. Multiple sets of parallel and inclined staggered slot plates 22 are installed at equal intervals on the top of the base plate 26 between the two end elastic clamping plates 21. The front and rear ends of the staggered slot plates 22 are provided with side slots with opposite openings. Adapter mounting slots 19 are provided between adjacent staggered slot plates 22 and between staggered slot plates 22 and end elastic clamping plates 21. The fiber optic adapter 23 to be installed is inserted into the adapter mounting slot 19 for positioning.

[0026] The end elastic plate 21 also has a side slot facing the misaligned slot plate 22. At the same time, a T-shaped bottom plate 20 is installed inside the adapter mounting slot 19. The bottom plate 20 and the side slot are respectively provided with bottom slots 25 and side blocks 24 at the corresponding optical adapters 23. By using the insertion of the side block 24 into the side slot and the insertion of the bottom slot 25 into the bottom plate 20, a triangular insertion positioning is formed, thereby realizing the quick installation and separation of the optical adapter 23.

[0027] The shapes of the elastic plates 21 on both sides, except for the L-shaped structure at the ends, can be the same or different. The specific structural design can be set according to the actual situation.

[0028] In the embodiments of the present invention, see Figure 1 , Figure 4The pull-out base 10 is designed with a U-shaped structure. Slide bars 14 are symmetrically installed on both sides of the pull-out tray 11. A slide rail 15 is provided on the inner wall of the pull-out base 10 corresponding to the slide bar 14. The inner end of the slide rail 15 is provided with a closed structure, and the outer end is provided with an open shape, which is suitable for the slide bar 14 to slide inside.

[0029] The inner end wall of the slide rail 15 is provided with a locking hole 16, and a locking pin is installed on the end wall of the slide bar 14 corresponding to the locking hole 16. The locking pin engages with the locking hole 16 and is used to fix the pull-out tray 11 after it is stored inside the pull-out base 10.

[0030] In one embodiment of the present invention, it should be noted that when multiple sets of adapter mounting bases 18 are installed inside the fiber optic adapter mounting base bayonet, they need to be elastically snapped together in the direction from bottom to top. At the same time, before the adapter mounting base 18 is installed into the fiber optic adapter mounting base bayonet, the optical adapter 23 to be installed needs to be pre-inserted into the corresponding adapter mounting slot 19 so that the upper adapter mounting base 18 can press the lower adapter mounting base 18, thereby increasing the stability of the installation.

[0031] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control.

[0032] During operation, the pull-out tray 11 is first pulled outward along the slide rail 15 on the inner wall of the pull-out base 10 via the slide bars 14 on both sides. When the locking pin at the end of the slide bar 14 engages with the locking hole 16 at the inner end of the slide rail 15, the pull-out tray 11 is fixed in the pulled-out state for easy operation;

[0033] Subsequently, the fiber optic adapter is installed by inserting the fiber optic adapter 23 downward along its adapter mounting slot 19, so that the bottom slot 25 of the fiber optic adapter 23 is connected to the bottom insert plate 20 fixed in the adapter mounting slot 19.

[0034] Meanwhile, the side inserts 24 on both sides of the optical adapter 23 are inserted into the side slots on the misaligned slot plate 22 or the end elastic slot plate 21 to form a stable triangular insertion positioning, thereby quickly fixing the optical adapter 23.

[0035] Next, starting from the bottom, push the adapter mounting base 18, with the fiber optic adapter 23 already installed, into the fiber optic adapter mounting base from bottom to top along the slot.

[0036] The L-shaped structure at the ends of the elastic retaining plates 21 on both sides of the adapter mounting base 18 elastically compresses and ultimately locks into place with the ends of the baffle 17, thereby achieving elastic fixation of the adapter mounting base 18 within the bayonet slot. The base plate of the upper adapter mounting base 18 provides pressure to the lower layer, increasing overall stability.

[0037] The optical fiber can be led out from the end of the optical adapter 23 and coiled on the coiling post 13 on the fiber coiling station 12. After all operations are completed, push the pull-out tray 11 back into the pull-out base 10.

[0038] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
