Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of combined optical cable junction boxes, and more specifically, to a combined optical cable junction box. Background Technology

[0002] An optical fiber splice is a section that joins two or more optical fiber cables together, used to connect different parts of the optical cable to form a continuous optical fiber link. Optical fiber splices are typically installed by professional technicians using specialized tools and equipment to ensure the quality and reliability of the connection. They can be connected at different locations during the optical fiber laying process, such as at the end, intermediate nodes, or branch points of the cable. The quality of the optical fiber splice is crucial to the performance of the optical fiber link. A good optical fiber splice should have low loss, high stability, and good waterproof and dustproof properties to ensure the quality of optical signal transmission. In practical applications, the type and technology of optical fiber splices may vary depending on the type of optical cable, the application scenario, and the requirements. Some common optical fiber splice technologies include mechanical splices, fusion splices, and active connectors.

[0003] In the process of connecting two or more optical cables together, a specialized connection tool—an optical cable splice closure—is required. There are many types of optical cable splice closures; based on their shape and structure, they can be divided into cap-type and horizontal optical cable splice closures. After analyzing and examining existing horizontal optical cable splice closures on the market, the inventors discovered some areas for improvement and optimization in the existing technology. Based on this background, the inventors made some improvements and optimizations to the optical cable splice closure based on the existing technology.

[0004] During the process of developing the utility model, the following problems were found in the existing technology: the existing optical cable junction box usually does not have a reliable optical cable fixing structure inside. If the optical cable is dragged by external force during the use of the optical cable junction box, the internal optical cable joint is prone to loosening, and it is not convenient to directly check the internal connection. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a combined optical cable junction box, which solves the technical problem that the optical cable junction box usually does not have a relatively reliable optical cable fixing structure inside, and the internal optical cable joint is prone to loosening if the optical cable is dragged by external force during use.

[0006] According to one aspect, at least one embodiment of this disclosure provides a combined optical cable junction box, comprising:

[0007] The box body and the outer cover, wherein the outer cover is rotatably connected to the box body by a pin;

[0008] A rectangular plate and a mating clamping assembly, wherein the rectangular plate is disposed inside the box body and the mating clamping assembly is disposed between the rectangular plate and the box body;

[0009] Anti-detachment components are disposed on both sides of the box body;

[0010] The docking clamping assembly includes a pair of sleeves, both of which are disposed on both sides of the box body. A pair of inserts are provided on both end faces of the rectangular plate. The rectangular plate is inserted into the sleeves through the inserts. The rectangular plate has a movable cavity inside, and several openings are provided at the top of the movable cavity.

[0011] As a further technical solution, a pair of round rods are connected to the movable sleeve inside the movable cavity, and several movable clamping plates are fixedly connected to the pair of round rods. Several fixed clamping plates are provided on the surface of the rectangular plate.

[0012] As a further technical solution, an adjusting screw is rotatably connected to one side of the movable cavity. One end of the adjusting screw is connected to one of the movable clamping plates by a threaded connection. Both the fixed clamping plate and the movable clamping plate have arc-shaped grooves on their surfaces.

[0013] As a further technical solution, the anti-detachment component includes a pair of slots, both of which are located at the top ends of the box body. Each slot is fitted with a plate, and the plate has a round hole on its surface and a clip on its side surface.

[0014] As a further technical solution, the sleeve is connected to an internally threaded sleeve by screwing, and a number of the slots are fitted with limit plates. Both ends of the box are provided with internally threaded tubes, and a pair of bolts are inserted into the limit plates. The bolts are screwed into the internally threaded tubes.

[0015] As a further technical solution, an observation window is provided on the surface of the outer cover.

[0016] As a further technical solution, the surface of the limiting plate and the upper end surface of the box are located on the same plane.

[0017] As a further technical solution, the front end of the sleeve has a forked four-claw structure.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. The beneficial effect of the mating clamping assembly in this disclosure is that the sleeve and the insert block cooperate to stably install the rectangular plate inside the junction box. The movable cavity, the through-hole, and the round rod provide movement space and guidance for the movable clamping plate. The adjusting screw drives the movable clamping plate to move, clamping the optical cable with the fixed clamping plate through the arc groove. This design effectively prevents the optical cable from shaking or shifting inside the junction box, ensuring stable optical cable mating. Furthermore, it is easy to operate, and the clamping force can be flexibly adjusted according to the thickness of the optical cable, greatly reducing the risk of unstable signal transmission due to loose optical cable and ensuring reliable optical signal transmission.

[0020] 2. The beneficial effect of the mating clamping assembly in this disclosure is that the slot provides installation positioning for the insertion plate. The round hole of the insertion plate is used to pass through the optical cable, and the sleeve and internal threaded sleeve can secure the optical cable. The limiting plate, internal threaded tube, and bolt work together to firmly fix the insertion plate. The four-claw structure of the sleeve can firmly grip the optical cable, and the forked design facilitates the insertion of the optical cable. This assembly fixes the optical cable as a whole, enhances the stability of the optical cable in the junction box, further improves the fixing effect of the junction box on the optical cable, reduces the impact of external forces on the optical cable connection, and ensures the stability and reliability of the optical cable connection.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-5 As shown, a combined optical cable junction box according to an embodiment of the present disclosure is illustrated, comprising:

[0035] The box body 1 and the outer cover 2 are rotatably connected to the box body 1 by a pin.

[0036] A rectangular plate 3 and a mating clamping assembly 4 are provided. The rectangular plate 3 is disposed inside the box body 1, and the mating clamping assembly 4 is disposed inside the rectangular plate 3 and the box body 1.

[0037] Anti-detachment component 5, wherein the anti-detachment component 5 is disposed on both sides of the box body 1;

[0038] The docking clamping assembly 4 includes a pair of sleeves 4-1, both of which are located on both sides of the box body 1. A pair of inserts 4-2 are provided on both end faces of the rectangular plate 3. The rectangular plate 3 is inserted into the sleeves 4-1 via the inserts 4-2. A movable cavity 4-3 is provided inside the rectangular plate 3. Several openings 4-4 are provided at the top of the movable cavity 4-3. A pair of round rods 4-5 are movably fitted inside the movable cavity 4-3. Several movable clamping plates 4-6 are fixedly connected to the pair of round rods 4-5. Several fixed clamping plates 4-7 are provided on the surface of the rectangular plate 3. An adjusting screw 4-8 is rotatably fitted to one side of the movable cavity 4-3. One end of the adjusting screw 4-8 is threadedly connected to one of the movable clamping plates 4-6. Arc-shaped grooves 4-9 are provided on the surfaces of both the fixed clamping plates 4-7 and the movable clamping plates 4-6.

[0039] In some examples, during the use of the combined optical cable junction box, a docking and clamping assembly 4 is designed to achieve the docking and clamping of the optical cable. This assembly includes a pair of sleeves 4-1 set on both sides inside the box body 1, which cooperate with the inserts 4-2 set on both sides of the rectangular plate 3. The inserts 4-2 are inserted into the sleeves 4-1, so that the rectangular plate 3 can be stably installed inside the box body 1, providing a basic platform for the docking and clamping of the optical cable. The movable cavity 4-3 opened inside the rectangular plate 3, as well as several openings 4-4 on the top of the movable cavity 4-3 and a pair of movable round rods 4-5, provide movable space and guide structure for the movable clamping plate 4-6. Several movable clamping plates 4-6 fixedly connected to the pair of round rods 4-5, together with several fixed clamping plates 4-7 set on the surface of the rectangular plate 3, can clamp the optical cable. An adjusting screw 4-8 rotated on one side inside the movable cavity 4-3, one end of which is connected to one of the movable clamping plates 4-6 through a threaded engagement. When the adjusting screw 4-8 is rotated, multiple movable clamps 4-6 will move synchronously with the round rod 4-5, moving closer to or further away from the fixed clamp 4-7. This enables the clamping or loosening of the optical cable placed in the arc groove 4-9 on the surface of the fixed clamp 4-7 and the movable clamp 4-6, ensuring that the optical cable is stably connected in the junction box and preventing signal transmission from being affected by loosening.

[0040] Through the coordinated work of components such as the sleeve 4-1, insert block 4-2, movable cavity 4-3, through port 4-4, round rod 4-5, movable clamping plate 4-6, fixed clamping plate 4-7, adjusting screw 4-8 and arc groove 4-9, the docking clamping assembly 4 realizes the function of docking and clamping the optical cable.

[0041] like Figures 1-5 As shown, this embodiment proposes that the anti-detachment component 5 includes a pair of slots 5-1, both of which are located at the top ends of the box body 1. Each slot 5-1 has a plate 5-2 inserted into it. The plate 5-2 has a round hole 5-3 on its surface. The side surface of the plate 5-2 is provided with a sleeve 5-4. The sleeve 5-4 is connected to an internally threaded sleeve 5-5 by screwing. Several slots 5-1 are fitted with limiting plates 5-6. Both ends of the box body 1 are provided with internally threaded tubes 5-7. A pair of bolts 5-8 are inserted into the limiting plates 5-6 and screwed into the internally threaded tubes 5-7.

[0042] In some examples, during the assembly of the modular optical cable junction box, an additional mating clamping assembly 4 is designed to secure the entire optical cable. This assembly includes a pair of slots 5-1 at both ends of the top of the box body 1. The slots 5-1 provide mounting positions for the insert plate 5-2. The circular holes 5-3 on the surface of the insert plate 5-2 allow the optical cable to pass through. A sleeve 5-4 on the side surface of the insert plate 5-2 is connected to an internally threaded sleeve 5-5 by screwing. Tightening the internally threaded sleeve 5-5 tightens the sleeve 5-4, thus securing the optical cable passing through the circular holes 5-3. The limiting plates 5-6 inserted into several slots 5-1 cooperate with the internally threaded tubes 5-7 set at both ends inside the box body 1 and the pair of bolts 5-8 inserted into the limiting plates 5-6. When the bolts 5-8 are screwed into the internally threaded tubes 5-7, the limiting plates 5-6 can be firmly fixed in the slots 5-1, thereby limiting the position of the insert plate 5-2, ensuring the stability of the insert plate 5-2, preventing the insert plate 5-2 from moving on the top of the box body 1, thus achieving reliable fixation of the entire optical cable, ensuring the stability of the optical cable in the junction box, and avoiding the impact of shaking and other factors on the optical cable connection quality.

[0043] Through the coordinated operation of components such as slot 5-1, insert plate 5-2, round hole 5-3, sleeve 5-4, internal thread sleeve 5-5, limit plate 5-6, internal thread tube 5-7 and bolt 5-8, the docking clamping assembly 4 achieves the function of fixing the entire optical cable.

[0044] For example, such as Figure 1 As shown, the outer cover 2 has an observation window 6 on its surface.

[0045] In some examples, the observation window 6 uses a transparent acrylic structure, allowing viewing of the interior while maintaining a protective effect.

[0046] For example, such as Figure 2 As shown, the surface of the limiting plate 5-6 is on the same plane as the upper surface of the box body 1.

[0047] In some examples, the integrity of the box body 1 can be guaranteed by using the same plane, ensuring a complete fit with the outer cover 2.

[0048] For example, such as Figure 3 As shown, the front end of the sleeve 5-4 has a forked four-claw structure.

[0049] In some examples, the four-claw structure can firmly grip the optical cable when tightening, and the fork makes it easy to open and insert the optical cable.

[0050] In practical use: First, select a stable and suitable installation location to place the box 1, ensuring it can stably support all operations of the optical cable splice box. Then, thread the optical cables to be connected one by one through the round holes 5-3 of the insert plate 5-2 inside the slot 5-1 at the top of the box 1. Using the forked four-pronged structure at the front end of the sleeve 5-4, carefully slip the sleeve 5-4 onto the optical cable, then slowly tighten the internal thread sleeve 5-5 to gradually tighten the sleeve 5-4, initially securing the optical cable. This step effectively prevents the optical cable from moving freely during subsequent operations. Next, precisely insert the insert plate 5-2 into the slot 5-1 at the top of the box 1, then insert the limiting plate 5-6 into the slot 5-1, and use a tool to screw the bolt 5-8 into the internal thread tube 5-7. The tight fit between the bolt 5-8 and the internal thread tube 5-7 firmly fixes the position of the insert plate 5-2. Next, accurately insert the inserts 4-2 on both sides of the rectangular plate 3 into the sleeves 4-1 on both sides of the housing 1, and carefully adjust the position of the rectangular plate 3 to ensure it is in the optimal state. Then, carefully place the optical cable into the arc-shaped grooves 4-9 on the surface of the fixed clamp 4-7 and the movable clamp 4-6 of the rectangular plate 3, and slowly rotate the adjusting screw 4-8. Under the guidance of the round rod 4-5, the movable clamp 4-6 smoothly approaches the fixed clamp 4-7, gradually clamping the optical cable to ensure the stability of the optical cable connection. Finally, gently close the outer cover 2 to complete the entire installation process.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
