Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of optical cable junction boxes, specifically to an optical cable junction box with a drop cable fixing bracket. Background Technology

[0002] In the construction and maintenance of optical fiber communication networks, the optical fiber splice closure is a key component for connecting and protecting optical fibers, and its performance directly affects the stability and reliability of the communication system. Drop optical cables are widely used in fiber-to-the-home and indoor cabling scenarios due to their small size, light weight, and flexible laying characteristics. However, traditional optical fiber splice closures have significant shortcomings in fixing drop optical cables, making it difficult to meet the stability and reliability requirements of modern communication networks.

[0003] In existing technologies, the fixing of drop optical cables to junction boxes mainly relies on simple clips or binding methods, which are not very secure. For example, clip structures are prone to loosening due to external pulling or environmental changes (such as temperature fluctuations or vibrations) during long-term use, leading to interruption of the optical cable connection or unstable signal transmission. Especially in outdoor or high-frequency vibration environments, the drawbacks of traditional fixing methods are more prominent, which may cause problems such as optical cable detachment and connector wear, increasing the risk of network failure and maintenance costs.

[0004] On the other hand, traditional junction boxes typically only provide a single fixing point and lack extended fixing capabilities. This can lead to damage to the optical cable due to excessive bending, affecting the transmission quality of the optical signal. Furthermore, the lack of extended fixing functionality results in inefficient use of space within the junction box, making it difficult to adapt to complex cabling needs and limiting its application in diverse scenarios.

[0005] With the widespread adoption of technologies such as 5G communication and fiber optic broadband, the requirements for the laying density and stability of drop optical cables in communication networks are constantly increasing. The shortcomings of traditional optical cable junction boxes in terms of fixation strength and extension capabilities have become a bottleneck restricting the efficiency and quality of communication network construction. Developing an optical cable junction box that can enhance the fixation strength of drop optical cables and provide extension capabilities is urgently needed. This is of great significance for improving the reliability of communication networks, reducing maintenance costs, and adapting to diverse cabling scenarios. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide an optical cable junction box with a drop cable fixing bracket, which solves the technical problem that the fixing of the drop optical cable to the junction box mainly relies on simple buckles or binding methods, which has poor firmness, lacks extension fixing effect, and may cause damage to the optical cable due to excessive bending, thus affecting the transmission quality of optical signals.

[0007] According to one aspect, at least one embodiment of this disclosure provides an optical cable junction box with a drop cable fixing bracket, comprising:

[0008] A main box and a secondary box, wherein the main box and the secondary box are connected;

[0009] A fixing and clamping assembly is disposed within the main box and the sub-box;

[0010] A thickening layer and an extension component, wherein the thickening layer is disposed outside the main box and the sub-box, and the extension component is disposed on the thickening layer;

[0011] The fixing and clamping assembly includes a pair of annular grooves, both of which are formed on the surfaces of the main box and the auxiliary box. A sealing gasket is fitted inside the annular groove, and a pair of inner sleeves are provided at both ends of the sealing gasket. A clamping inner frame is fixed inside the main box.

[0012] As a further technical solution, a through cavity is provided in the inner frame of the clamping device, and a pair of internal threaded sleeves are provided at both ends of the main box. The internal threaded sleeves are located on both sides of the inner frame of the clamping device. A pressure plate is installed in the through cavity, and bolts are installed at both ends of the pressure plate.

[0013] As a further technical solution, the extension assembly includes a pair of extension rods, which are respectively fixed at opposite ends of the thickened layer, and a sleeve is provided at one end of each extension rod.

[0014] As a further technical solution, a reinforcing rod is connected between the sleeve and the thickened layer, and a pair of connecting holes are opened on the surface of the sleeve, wherein the connecting holes in the sleeve at both ends of the main box have a stepped structure.

[0015] As a further technical solution, the inner sleeve surface is provided with a raised layer, which has a wavy structure.

[0016] As a further technical solution, the inner sleeve is an arch-shaped structure with double grooves.

[0017] As a further technical solution, the cavity is laterally inserted and tightly fitted into the inner frame.

[0018] As a further technical solution, a pair of bosses are provided on the inner surface of the sleeve, and the bosses have an arc-shaped surface structure.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. The beneficial effect of the fixing and tightening assembly in this disclosure is that, through the cooperation of components such as the annular groove, sealing gasket, inner sleeve, inner clamping frame, pressure plate, and bolts, multi-level secure fixing of the drop optical cable is achieved. The bow-shaped double-groove structure of the inner clamping frame can fix two optical cables simultaneously. The through-cavity design allows the pressure plate to fully compress the optical cable. The corrugated convex inner sleeve enhances the friction with the optical cable. The screw-on connection between the bolt and the internal threaded sleeve provides adjustable tightening force, ensuring that the optical cable has no possibility of loosening in the junction box. This effectively solves the problem of poor firmness of traditional buckle or binding methods. Even under high-frequency vibration or external pulling force, it can maintain a stable connection, reduce the risk of network failure, and extend the service life of the equipment.

[0021] 2. The beneficial effects of the extension component in this disclosure are that the design of the extension rod and the sleeve extends the fixing range from the inside of the junction box to the outside. Through the reinforcing rod and the stepped connection hole, various fasteners can be used to fix the optical cable in sections to both ends of the junction box. The pressure of the arc-shaped boss supports the optical cable before it enters the box, avoiding damage caused by the optical cable due to sag or excessive bending. At the same time, it makes reasonable use of space to guide the optical cable, reducing the messy tangling inside the box. It adapts to complex scenarios where multiple optical cables are laid in parallel or bent and turned, improving the cabling efficiency and aesthetics. The extension and fixing effect makes the optical cable bear the force evenly, further ensuring the stability of optical signal transmission and meeting the diverse cabling needs of modern communication networks.

[0034] like Figures 1-4 As shown, it illustrates an optical cable junction box with a drop cable fixing bracket according to an embodiment of the present disclosure, comprising:

[0035] The main box 1 and the secondary box 2 are connected.

[0036] A fixing and clamping component 4 is disposed within the main box 1 and the secondary box 2;

[0037] Thickened layer 3 and extension component 5, the thickened layer 3 is disposed outside the main box 1 and the sub-box 2, and the extension component 5 is disposed on the thickened layer 3;

[0038] The fixing and clamping assembly 4 includes a pair of annular grooves 4-1, both of which are formed on the surfaces of the main box 1 and the auxiliary box 2. A sealing gasket 4-2 is installed inside the annular groove 4-1 and 4-3. A pair of inner sleeves 4-3 are provided at both ends of the sealing gasket 4-2. A clamping inner frame 4-4 is fixed inside the main box 1. A through cavity 4-5 is formed in the clamping inner frame 4-4. A pair of internal threaded sleeves 4-6 are provided at both ends of the main box 1. The internal threaded sleeves 4-6 are located on both sides of the clamping inner frame 4-4. A pressure plate 4-7 is installed inside the through cavity 4-5 and 4-3. Bolts 4-8 are installed at both ends of the pressure plate 4-7.

[0039] In some examples, during the use of the optical cable splice closure, a fixing and tightening assembly 4 is designed to securely fix the optical cable. This assembly includes a pair of annular grooves 4-1 formed on the surfaces of the main box 1 and the auxiliary box 2. A sealing gasket 4-2 fitted inside the annular groove 4-1 (4-3) enhances the sealing performance of the splice closure and provides a basic structure for fixing the optical cable. The inner sleeves 4-3 at both ends of the sealing gasket 4-2 cooperate with the inner clamping frame 4-4 fixed inside the main box 1. The through cavity 4-5 in the inner clamping frame 4-4 provides space for the optical cable to pass through. Internally threaded sleeves 4-6, located at both ends inside the main box 1, are situated on both sides of the inner clamping frame 4-4. Pressure plates 4-7 fitted inside the through cavity 4-5 (4-3) are screwed onto the internally threaded sleeves 4-6 via bolts 4-8 at both ends. When bolt 4-8 is tightened, pressure plate 4-7 moves toward inner frame 4-4, pressing the optical cable tightly between inner frame 4-4 and pressure plate 4-7, ensuring the optical cable is stably fixed in the junction box, and preventing loosening of the connection due to shaking or external force, which would affect signal transmission.

[0040] Through the coordinated work of components such as the annular groove 4-1, sealing gasket 4-2, inner sleeve 4-3, inner clamping frame 4-4, internal threaded sleeve 4-6, through cavity 4-5, pressure plate 4-7 and bolt 4-8, the fixing and tightening assembly 4 achieves the function of firmly pressing the optical cable inside the junction box.

[0041] like Figures 1-4 As shown, this embodiment proposes that the extension component 5 includes a pair of extension rods 5-1, which are respectively fixed at opposite ends of the thickened layer 3. One end of the extension rod 5-1 is provided with a sleeve 5-2, and a reinforcing rod 5-3 is connected between the sleeve 5-2 and the thickened layer 3. A pair of connecting holes 5-4 are opened on the surface of the sleeve 5-2, wherein the connecting holes 5-4 in the sleeve 5-2 at both ends of the main box 1 are stepped structures.

[0042] In some examples, to accommodate the fixing requirements of optical cables of different lengths and enhance the support effect on the optical cables, an extension component 5 is designed. This component includes a pair of extension rods 5-1 fixed at opposite ends of the thickened layer 3. A sleeve 5-2 set at one end of the extension rod 5-1 is connected to the thickened layer 3 through a reinforcing rod 5-3, which can enhance the structural strength of the extension component 5. Among the pair of connection holes 5-4 opened on the surface of the sleeve 5-2, the connection holes 5-4 of the sleeve 5-2 at both ends of the main box 1 are stepped. This design can accommodate fasteners of different specifications (such as bolts 4-8, buckles, etc.). The extension component 5 effectively extends the fixing length of the optical cable, so that the optical cable can be fixed a certain distance before entering the junction box, dispersing the force on the optical cable at the entrance of the junction box, reducing the impact of the optical cable sag or swing on the internal connection of the junction box, and further improving the reliability and stability of the optical cable fixing.

[0043] Through the coordinated operation of components such as extension rod 5-1, sleeve 5-2, reinforcing rod 5-3, and connecting hole 5-4, the extension assembly 5 achieves the functions of extending the fixed length of the optical cable and enhancing the fixing effect.

[0044] For example, such as Figure 3 As shown, the inner sleeve 4-3 has a raised layer on its surface, and the raised layer has a wavy structure.

[0045] In some examples, the presence of wavy convex layers can increase the tightness and stability of the connection between the inner sleeve 4-3 and the main box 1 and the inner box.

[0046] For example, such as Figure 1 As shown, the inner sleeve 4-4 is an arch-shaped structure with double grooves.

[0047] In some examples, the bow-shaped structure allows the inner frame 4-4 to have two slots, enabling the simultaneous fixing of two optical cables.

[0048] For example, such as Figure 4 As shown, the through cavity 4-5 extends laterally through and tightly fits the inner frame 4-4.

[0049] In some examples, the through-structure allows the pressure plate 4-7 to fit snugly against the inner frame 4-4, completely securing the optical cable inside and preventing it from loosening or falling off.

[0050] For example, such as Figure 1 As shown, a pair of bosses 6 are provided on the inner surface of the sleeve 5-2, and the bosses 6 have an arc-shaped surface structure.

[0051] In some examples, the arc-shaped boss 6 structure can increase the pressure on the optical cable and improve the secure fixation of the optical cable.

[0052] In actual use: Connect and assemble the main box 1 and the auxiliary box 2. Insert the drop cable through the sleeve 5-2 at one end of the main box 1, and through the annular groove 4-1 on the surface of the main box 1 into the box. Let the cable pass through the cavity 4-5 of the inner sleeve 4-4. After adjusting the position of the cable, place the pressure plate 4-7 into the cavity 4-5. Use bolts 4-8 to pass through the pressure plate 4-7 and screw it into the internal threaded sleeve 4-6 inside the main box 1 to fix it. Tightening the bolts 4-8 will cause the pressure plate 4-7 to squeeze the cable, which, together with the inner sleeve 4-4, will secure the cable firmly. Fixed inside the main box 1, the secondary box 2 uses the same fixing and clamping component 4 to fix the other end of the optical cable. The extension rod 5-1 and the sleeve 5-2 of the extension component 5 can fix the part of the optical cable before it enters the junction box in sections. The structural stability is enhanced by the reinforcing rod 5-3, and the arc-shaped protrusion 6 in the sleeve 5-2 increases the pressure on the optical cable to ensure that the optical cable is effectively fixed inside and outside the junction box. At the same time, the sealing gasket 4-2 enhances the sealing of the annular groove 4-1 to prevent external moisture from entering the box and affecting the optical cable connection.

[0053] 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.
