Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to a horizontal optical cable splice box. Background Technology

[0002] In optical fiber communication networks, optical cables are connected by optical fibers to form the network. Optical fiber splice boxes, as a type of optical cable connection device, are widely used in optical fiber communication networks. They are suitable for various installation environments of optical cables, including aerial, duct, and direct burial. They are effectively waterproof, flame-retardant, and impact-resistant, providing excellent protection against the stretching and torsion of the optical cable, and ensuring excellent communication quality even in harsh natural environments.

[0003] However, existing optical cable splice boxes typically only have one set of fusion splice trays inside, resulting in a limited number of fiber cores that can be fused, which is insufficient for splicing high-core-count optical cables. Furthermore, when splicing multiple optical cables, the number of fiber cores being fused is even greater, and one set of fusion splice trays cannot meet the fiber fusion requirements. Therefore, more optical cable splice boxes need to be installed, leading to increased costs and hindering business development. Utility Model Content

[0004] The purpose of this invention is to provide a horizontal optical cable splice box that can fuse more cores and ensure splicing stability.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions:

The rotating shaft on the rear side of the previous fusion splice tray is inserted into the hinge hook on the rear side of the next fusion splice tray, so that the two adjacent fusion splice trays are hinged together.

[0008] In one embodiment, a fastening platform is provided on the lower front side of the fusion splice tray, and a buckle is provided on the upper front side. When the previous set of fusion splice trays closes to the next set of fusion splice trays, the buckle on the front side of the next set of fusion splice trays will engage with the fastening platform on the front side of the previous set of fusion splice trays.

[0009] In one embodiment, the top of the card slot is provided with a positioning boss, and the baffle is provided with a positioning hole corresponding to the positioning boss. The positioning boss is inserted into the positioning hole with an interference fit so that the baffle covers the fiber melting tray.

[0010] In one embodiment, the box body is further provided with a plurality of fiber-blocking ears or a plurality of straps, and the plurality of fiber-blocking ears or a plurality of straps are arranged around the melting coil.

[0011] In one embodiment, cable inlet and outlet holes are respectively opened on both sides of the box body, and rubber plugs are installed in the cable inlet and outlet holes. The rubber plugs are provided with multiple coaxial steps of different diameters in sequence.

[0013] In one embodiment, a latch is provided on the front side of the box body, and a locking groove corresponding to the latch is provided on the front side of the box lid. The latch is snapped into the locking groove to lock the box lid and the box body, and a sealing gasket is also provided between the box lid and the box body.

[0014] In one embodiment, the bottom of the box is also connected to a hanger, and a clamp is provided at the front end of the hanger. The clamp is connected to the hanger with screws.

[0033] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Please see Figures 1 to 8 A horizontal optical cable splice box includes a box body 100, a box cover 200, and a fiber splice tray 300. The box cover 200 is hinged to the rear side of the box body 100, allowing the box cover 200 to be rotatably opened or closed relative to the box body 100. A support column 110 and a fixing column 120 are provided inside the box body 100. Multiple sets of fiber splice trays 300 are provided, and the rear sides of the multiple sets of fiber splice trays 300 are sequentially hinged, allowing the multiple sets of fiber splice trays 300 to be stacked. The bottommost fiber splice tray... The fiber tray 300 is mounted on the support column 110 and connected to the fixed column 120. The uppermost fiber fusion tray 300 is covered with a cover plate 400. The fiber fusion tray 300 is provided with multiple welding slots 310 for embedding heat shrink protective tubes, and the inner wall of the fiber fusion tray 300 is provided with several locking positions 320. The top of the adjacent fiber fusion trays 300 is covered with baffles 500. When multiple sets of fiber fusion trays 300 are stacked, they can be bundled by cable ties 600.

[0037] Specifically, in this embodiment, a support column 110 and a fixing column 120 are provided inside the housing 100. The support column 110 supports the splice tray 300, and screws pass through the splice tray 300 and are threadedly connected to the fixing column 120, thus fixing the splice tray 300 to the fixing column 120. This allows the splice tray 300 to be suspended, creating more space below it to store more fiber optic redundancy, thus improving the overall layout of the optical cable splice box. The layout is reasonable; furthermore, multiple sets of fiber optic splice trays 300 are arranged, and these sets are hinged sequentially, allowing them to be stacked. This reduces the space occupied by the multiple sets of splice trays 300 and avoids excessively increasing the size of the optical cable splice box. The bottom splice trays 300 are supported and fixed by support columns 110 and fixing columns 120, while the top splice trays 300 can be covered by cover plates 400. Each set of splice trays 300 has multiple... Each fusion splice slot 310, through multiple sets of fusion splice trays 300 and multiple fusion splice slots 310 on each set of fusion splice trays 300, can splice more fibers. After the fiber is spliced, the fusion splice tray 300 can be covered by a baffle 500 to prevent the fiber from scattering outside the fusion splice tray 300 and ensure the stability of the fiber splice. After multiple sets of fusion splice trays 300 have been spliced, the multiple sets of fusion splice trays 300 can be closed and stacked, and then the cover plate 400 covers the top one. The fiber fusion splice tray 300 is covered, and after covering, multiple stacked fiber fusion splice trays 300 can be bundled together with cable ties 600 to better improve the stability of fiber optic splicing. The several slots 320 distributed on the inner wall of the fiber fusion splice tray 300 can be used to easily insert the optical fiber into the fiber fusion splice tray 300 for coiling, thereby facilitating fiber optic splicing. The heat shrinkable protective tubes covering the fiber optic splice points can also be easily inserted into the splice slots 310, making the overall structural design of the fiber fusion splice tray 300 reasonable.

[0038] Furthermore, to facilitate the covering of the fusion splice tray 300 by the baffle 500, a positioning boss 321 is provided on the top of the locking position 320, and a positioning hole 510 corresponding to the positioning boss 321 is provided on the baffle 500. The positioning boss 321 is interference-fitted into the positioning hole 510 so that the baffle 500 covers the fusion splice tray 300, thereby preventing the optical fiber from falling outside the fusion splice tray 300 and ensuring the stability of the optical fiber splice. At the same time, to facilitate the installation personnel to splice multiple sets of fibers... To check the amount of fiber fusion in the coil 300, the baffle 500 can be made of transparent material. When the upper fiber fusion coil 300 is flipped open, the amount of fiber fusion in the lower fiber fusion coil 300 can be clearly seen through the transparent baffle 500. If the lower fiber fusion coil 300 also has a fiber fusion slot 310, fiber fusion can be performed in this fiber fusion coil 300, which makes it convenient for installers to manage and operate multiple fiber fusion coils 300, thereby ensuring that more cores can be fused.

[0039] In addition, since more cores need to be spliced, the number of optical fibers will also increase accordingly. To facilitate the coiling of the increased fiber redundancy, several fiber guide ears 130 or several binding straps 140 are provided inside the housing 100, and these fiber guide ears 130 or binding straps 140 are arranged around the splice tray 300. When the number of cores is small, fiber guide ears 130 can be set around the splice tray 300 to facilitate the coiling of optical fibers. When multiple optical cables are connected, each optical cable has multiple optical fibers, so the number of cores will be larger. In this case, binding straps 140 can be set around the splice tray 300 to facilitate the binding of optical fibers in multiple optical cables, thereby better protecting the splice and preventing the optical fibers from becoming messy inside the housing 100, thus facilitating subsequent installation and maintenance.

[0040] Please see Figures 4 to 6 When performing fiber splicing with a higher core count, multiple sets of fiber splicing trays 300 need to be flipped open. To achieve this flipping, in this embodiment, a rotating shaft 330 is provided at both ends of the lower rear side of the fiber splicing tray 300, and a hinge hook 340 corresponding to the rotating shaft 330 is provided at both ends of the upper rear side. At the same time, a fastening platform 350 is provided at the lower front side of the fiber splicing tray 300, and a buckle 360 ​​is provided at the upper front side. When the previous set of fiber splicing trays 300 closes to the next set of fiber splicing trays 300, the buckle 360 ​​on the front side of the next set of fiber splicing trays 300 will engage with the fastening platform 350 on the front side of the previous set of fiber splicing trays 300.

[0041] By engaging the pivot 330 on the rear side of the previous set of fusion splice trays 300 with the hinge hook 340 on the rear side of the next set of fusion splice trays 300, the two adjacent sets of fusion splice trays 300 can be hinged together. This hinge allows the fusion splice trays 300 to be flipped open, facilitating fiber splicing on each set of fusion splice trays 300 by installers and simplifying subsequent installation and maintenance. After splicing multiple sets of fusion splice trays 300, they can be flipped closed to allow for stacking. After stacking, the latch 360 on the front side of the next set of fusion splice trays 300 is engaged with the latch 350 on the front side of the previous set of fusion splice trays 300 to lock the multiple sets of fusion splice trays 300 sequentially, ensuring that the fusion splice trays 300 do not easily flip over and thus guaranteeing the stability of the fiber splicing within the multiple sets of fusion splice trays 300.

[0042] Since the top set of fiber melting trays 300 is covered by a cover plate 400, and in order to facilitate the connection between the cover plate 400 and the top set of fiber melting trays 300, a pivot can also be provided on the rear side of the cover plate 400, and a latching platform can also be provided on the front side. The pivot can make the cover plate 400 and the top set of fiber melting trays 300 hinged, so as to facilitate the opening or closing of the cover plate 400. After the top set of fiber melting trays 300 has finished melting, the latching platform of the cover plate 400 can be fastened into the latch 360 of the top set of fiber melting trays 300 to close the cover plate 400, thereby protecting the inside of the fiber melting trays 300 and ensuring the stability of fiber melting.

[0043] Please see Figure 3 and Figure 9 To facilitate the insertion of optical cables into the optical cable splice box for fiber splicing, this embodiment provides cable entry / exit holes 150 on both sides of the box 100. The number of cable entry / exit holes 150 can be set according to actual needs. A rubber plug 151 is installed inside each cable entry / exit hole 150. When the cable entry / exit hole 150 is not needed, it can be sealed by the rubber plug 151. When the cable entry / exit hole 150 is needed, the optical cable can be inserted through the rubber plug 151. Furthermore, to accommodate different... For the installation of optical cables of different diameters, the rubber plug 151 in this embodiment is provided with multiple coaxial steps 152 of different diameters. The multiple steps 152 provide different sizes of apertures, so that the installer can select the step 152 that best matches the outer diameter of the cable being installed (usually the step is slightly smaller than the outer diameter of the cable). Therefore, it is not necessary to equip each type of cable with a dedicated rubber plug 151, which greatly improves the versatility and flexibility of the rubber plug 151, reduces the types of spare parts, and makes the rubber plug 151 adaptable to optical cables of different diameters in the range of 6mm-22mm.

[0044] For further details, please refer to Figure 3 and Figure 7 To make the optical cable connection more stable, in this embodiment, a wire clamping unit 160 is provided on both the inner and outer sides of the cable entry and exit through hole 150. The wire clamping unit 160 includes a fixing block 161 and a wire clamping clip 162. The fixing block 161 is connected to the housing 100. The wire clamping clip 162 can be connected to the fixing block 161 by a fastener, which can be a screw. The fixing block 161 is provided with a first arc-shaped groove 163. One side of the wire clamping clip 162 is provided with a second arc-shaped groove 164 corresponding to the first arc-shaped groove 163.

[0045] When the optical cable is inserted into the housing 100 through the cable inlet / outlet hole 150, it passes through the first arc-shaped groove 163 of the fixing block 161. After insertion, the wire clamp 162 can be connected to the fixing block 161, so that the second arc-shaped groove 164 of the wire clamp 162 corresponds to the first arc-shaped groove 163. Then, the fasteners are tightened to secure the optical cable with the first arc-shaped groove 163 and the second arc-shaped groove 164, ensuring the stability of the optical cable connection and guaranteeing the fiber splicing effect. In order to secure optical cables of different diameters, a protrusion is also provided on the other side of the wire clamp 162. 165, and a third arc-shaped groove 166 corresponding to the first arc-shaped groove 163 is provided on the protrusion 165. When the diameter of the optical cable is small, the clamping clip 162 can be flipped so that the protrusion 165 is placed in the first arc-shaped groove 163, so that the third arc-shaped groove 166 cooperates with the first arc-shaped groove 163 to clamp the optical cable with a smaller diameter. By cooperating with the first arc-shaped groove 163 with the second arc-shaped groove 164 and the third arc-shaped groove 166 respectively, optical cables with different diameters in the range of 6mm-22mm can be clamped, thereby improving the compatibility and practicality of the clamping unit 160.

[0046] In order to better secure the optical cable, several locking posts 167 are provided in the first arc groove 163, the second arc groove 164 and the third arc groove 166. The locking posts 167 can better secure the optical cable, thereby improving its connection stability.

[0047] Please see Figure 3 and Figure 8 In order to protect more optical fibers and splice points inside the housing 100, in this embodiment, a latch 170 is provided on the front side of the housing 100, and a locking groove 210 corresponding to the latch 170 is provided on the front side of the cover 200. When the optical cable is spliced, the cover 200 can be flipped and closed, and the latch 170 on the front side of the housing 100 can be fastened into the locking groove 210 on the front side of the cover 200, thereby locking the cover 200 and the housing 100 to protect the inside of the housing 100.

[0048] In order to achieve a seal between the cover 200 and the body 100, a sealing gasket 180 is arranged around the top of the body 100. When the cover 200 is flipped over and closed on the body 100, the sealing gasket 180 can ensure the seal between the cover 200 and the body 100. Combined with the rubber plug 151, the overall seal of the optical cable splice box can be achieved.

[0049] Please see Figure 3 To facilitate the installation of the horizontal optical cable splice box, a hanger 190 is connected to the bottom of the box body 100, and a clamp 191 is set at the front end of the hanger 190. The clamp 191 is connected to the hanger 190 with screws. The horizontal optical cable splice box can be installed outdoors on a pole or overhead using the hanger 190. When using pole installation, the clamp 191 and the hanger 190 are respectively clamped on both sides of the installation pole, and then tightened with screws, thus facilitating the installation and fixation of the horizontal optical cable splice box.

[0050] Finally, in this embodiment, a grounding bracket and a grounding wire can also be provided inside the box 100. The grounding bracket and grounding wire are existing technologies, so they will not be described in detail here. In addition, the cable ties 600 and the binding straps 140 in this embodiment can both be Velcro. Furthermore, the box 100 and the box cover 200 are made of ABS+PC alloy material, which makes the horizontal optical cable splice box stronger and more drop-resistant.

[0051] In summary, in this embodiment, the hinges between the cover 200 and the body 100, and the hinges between the multiple sets of fusion splice trays 300, facilitate the splicing of optical fibers, the coiling of optical fiber redundancy, and wiring operations. Furthermore, the multiple sets of fusion splice trays 300 allow for the splicing of a larger quantity of optical fibers, thereby increasing the core count. At the same time, the cover plate, baffle 500, and cable ties 600 ensure the splicing stability within the multiple sets of fusion splice trays 300, thus guaranteeing the quality of the horizontal optical cable splice box after splicing.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
