Description

Technical Field

[0001] This invention relates to the field of optical fiber communication infrastructure technology, and more specifically, to a miniature, invisible optical cable storage box for home use. Background Technology

[0002] With the increasing popularity of FTTR (Fiber to the Room) and gigabit broadband technologies, the demand for indoor fiber optic cabling is growing. To minimize the impact on the aesthetics of interior decoration, miniature invisible optical cables with a diameter of about 1.2mm are now commonly used for installation in homes, along with cable management boxes for cable storage and management.

[0003] However, existing cable storage boxes have the following prominent problems in practical applications: First, there is a lack of integrated storage design for the connectors at both ends of the optical cable. In the factory shipping state, fiber optic connectors and fiber optic adapters are often scattered inside or outside the box, lacking a reliable securing structure. Transportation vibrations can easily cause connector damage or optical cable scattering.

[0004] Second, the inner connector is prone to twisting during the cable pulling process. When the construction workers pull the optical cable outward, the optical cable wound on the cable storage reel causes the reel to rotate. However, if the inner end of the optical cable does not move with the reel, it will twist relative to the reel, causing the micro-fiber to be damaged or the optical attenuation to increase due to twisting.

[0005] Third, there is a lack of a reliable rigid locking mechanism. Existing cable storage boxes rely heavily on friction damping to stop the reel after it has been extended to the required length, failing to provide a reliable rigid locking mechanism. During use, even a slight external force can cause the cable storage reel to retract or slip, resulting in the optical cables inside the reel becoming scattered or even broken.

[0006] Fourth, the internal connectors lack effective terminal fixing methods after construction. In traditional solutions, the internal connectors are either always fixed to the panel and cannot be exposed for use, or they are suspended inside the box and difficult to connect, making it impossible to directly convert the cable storage box into a standard information panel that can be plugged into by terminal equipment after the cabling is completed.

[0007] The aforementioned defects limit the construction efficiency and reliability of miniature invisible optical cables in FTTR cabling scenarios. Summary of the Invention

[0008] The technical problem to be solved by the present invention is that the inner optical fiber of traditional micro optical cable storage equipment is easily twisted and broken when the cable is pulled out, and the lack of a rigid locking mechanism after the length is fixed can easily lead to the retraction of the coil. In order to overcome the above defects of the prior art, the present invention provides a micro invisible optical cable storage box for home use.

[0009] This invention provides a miniature, invisible fiber optic cable storage box, comprising: The housing contains a support column with a limiting gear, a receiving groove, and a fixing groove. The cable storage reel is rotatably fitted onto the support column, and its top is provided with a follow-up groove and a limiting slide groove containing a high-position support platform and a low-position locking groove. The optical cable is wound around the cable storage reel, with optical fiber connectors and optical fiber adapters connected to both ends, and has an initial storage state in which both ends are respectively embedded in the receiving groove and the follower groove. The locking knob is located above the cable storage tray. The bottom end is provided with a locking tooth that engages with the limiting gear. The side wall has a protruding limiting post that is slidably connected to the limiting groove. The locking knob has an unlocked state and a locked state: In the unlocked state, the limit post slides to the high support platform, and the locking teeth disengage from the limit gear to release the rotation limit on the cable storage tray, so that the follower groove and the embedded fiber optic adapter can rotate synchronously with the cable storage tray. In the locked state, the limit post slides to the low position slot, and the locking teeth mesh with the limit gear to lock the cable storage tray; the fiber optic adapter has the working state of being pulled out from the follower slot and transferred and embedded into the fixed slot after construction is completed.

[0010] Compared with existing technologies, the miniature invisible fiber optic cable storage box disclosed in this application has the following advantages: By initially embedding the fiber optic connector and fiber optic adapter into the receiving slot and the follower slot respectively, shock protection is achieved during factory and transportation conditions; during unlocking and cable pulling, the inner fiber optic adapter is secured in the follower slot and rotates coaxially and at the same frequency as the cable storage tray, avoiding the risk of twisting and breakage of the inner fiber optic cable during long-distance cable pulling; during fixed-length locking, the limit post falls into the low-position slot, causing the knob to sink, so that the end face teeth and the limit gear rigidly engage to lock the cable storage tray, providing anti-pull and anti-rebound force, solving the problem of easy slippage and tray scattering in traditional friction damping structures; at the same time, after construction, the fiber optic adapter can be pulled out from the follower slot and transferred and secured to the fixed slot on the edge of the shell, so that the cable storage box can be directly upgraded into a standard fiber optic information panel on the wall, realizing full life cycle workstation flow and integrated plug-and-play experience.

[0011] In one possible implementation, the limiting slide also includes a transition slide for providing a smooth lifting path when switching between an unlocked state and a locked state, the transition slide connecting the high-position support platform and the low-position slot.

[0012] Compared with existing technologies, when switching between the unlocked and locked states, a smooth guide path is provided for the axial lifting and lowering of the limit post, which significantly improves the smoothness of the knob lifting and pressing operation and reduces structural wear.

[0013] In one possible implementation, the surface of the high-level support platform is provided with a stop protrusion to prevent the limiting post from sliding from the high-level support platform into the low-level slot when the cable storage reel rotates.

[0014] Compared with existing technologies, the physical limitation of the limiting post by the stop protrusion effectively prevents the unexpected interruption and locking caused by the limiting post accidentally sliding back to the low position slot due to vibration or inertia when the cable storage tray rotates due to the pulling of the optical cable in the unlocked state.

[0015] In one possible implementation, the low-position slot has a vertical lateral wall for preventing the locking knob from rotating circumferentially relative to the cable storage reel; in the locked state, the limiting post abuts against the vertical lateral wall.

[0016] Compared with existing technologies, circumferential anti-rotation is achieved by the radial contact between the vertical side wall and the limiting post. Combined with the meshing of the locking teeth and the limiting gear, an interlocking three-dimensional rigid linkage locking mechanism is formed, which greatly enhances the anti-torsional strength in the locked state.

[0017] In one possible implementation, the support column is provided with an elastic buckle on its outer side, the cable storage reel includes an upper disc, a lower disc and a winding column connecting the two, the follower groove is provided on the surface of the upper disc, the limiting slide groove is provided on the top of the winding column, the inner wall of the winding column is provided with an annular boss, the winding column is sleeved on the outer side of the support column, and the annular boss and the elastic buckle are engaged to restrict the cable storage reel from detaching from the support column axially.

[0018] Compared with existing technologies, the combination of the annular boss and the elastic buckle ensures that the cable storage reel rotates smoothly around the axis while providing reliable axial bidirectional limiting, preventing the cable storage reel from axially falling off when under the force of cable pulling.

[0019] In one possible implementation, the upper disc is further provided with at least one radially extending optical cable guide ear, the optical cable guide ear is provided with a plurality of optical cable guide slots, and the top of the optical cable guide ear protrudes from the surface of the upper disc for use in limiting the storage of optical cables.

[0020] Compared with existing technologies, the use of radially protruding optical cable guide ears enables independent partitioning and splicing management of multiple optical cable segments, avoiding excessive bending or tangling of optical cables in the reel due to interlayer compression, thus improving the neatness of the wiring in the reel and the smoothness of subsequent cable pulling.

[0021] In one possible implementation, the housing has at least one cable inlet on its side, and the housing has a set of cable guide brackets inside each cable inlet for preventing bending and limiting the cable when it is pulled outward in the unlocked state. The cable routing guide bracket includes multiple spaced arc-shaped guide plates, which form an arc-shaped cable routing channel. At least one of the arc-shaped guide plates is provided with a limiting pressure plate to restrict the axial movement of the optical cable.

[0022] Compared with existing technologies, by using multiple arc-shaped guide plates in conjunction with limiting pressure plates, the optical cable is strictly guided and axially fixed during the dynamic wire drawing process to prevent bending and limit the optical cable, thus physically avoiding the increase in optical attenuation or jamming caused by excessively small bending radius.

[0023] In one possible implementation, the housing is provided with a plurality of arc-shaped partitions around the support column to limit the range of the optical cable winding around the winding column.

[0024] Compared with existing technologies, the use of arc-shaped partitions to define the safe winding boundary of the optical cable around the winding post effectively avoids the hidden danger of the optical cable falling off due to slack and getting stuck in the mechanical dead corner inside the shell.

[0025] In one possible implementation, the fixing slot is located on the inner edge of the housing, with its opening facing the outer side of the housing, so that the fixed fiber optic adapter forms a standard plug-in interface to the outside.

[0026] Compared with existing technologies, the outward-facing fixed slot design allows the fiber optic adapter to be directly exposed after the work station is moved, thus seamlessly forming a standard wall-mounted plug-and-play communication socket interface.

[0027] In one possible implementation, the top surface of the locking knob is provided with status indicators, including an unlocked status indicator, a locked status indicator, and a rotating arrow corresponding to the switching direction.

[0028] Compared with existing technologies, by setting intuitive status indicators and rotation arrows on the top surface of the locking knob, clear and unambiguous human-computer interaction visual guidance is provided for users and construction personnel to switch between unlocking and locking states.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0035] See Figures 1 to 9 As shown in the figure, this application discloses a miniature invisible optical cable storage box, including: a housing 1, a cable storage tray 2, an optical cable 3, and a pull-and-rotate locking knob 4. The two ends of the optical cable 3 are respectively connected to an optical fiber connector 31 and an optical fiber adapter 32.

[0036] The housing 1 is generally square in shape and includes a sealed cavity formed by the fastening of a base 11 and a top cover 12. The base 11 and the top cover 12 are detachably connected by a snap-fit ​​mechanism. The back of the base 11 has multiple mounting holes for fixing it to a wall or inside a low-voltage electrical box.

[0037] In this embodiment, a hollow support column 13 protruding upwards is provided at the center of the base 11. A fixed limiting gear 131 is provided around the top outer ring of the support column 13, serving as a stationary end for mechanical locking. At least one elastic buckle 132 is provided on the outer wall of the support column 13 to limit the axial displacement of the cable storage reel 2. An arc-shaped partition baffle 17 is provided around the support column 13 of the base 11 to limit the winding range of the optical cable 3 and prevent the optical cable 3 from scattering and getting stuck in dead corners.

[0038] At least one cable inlet 5 is provided on the edge sidewall of the base 11; in a preferred embodiment, cable inlets 5 can be provided on multiple sides of the base 11 to accommodate cable exit in different directions, such as... Figure 1 and Figure 6 In the embodiment shown, the base 11 is provided with at least one inlet 5 for optical cable outgoing.

[0039] On the inner edge of the base 11 of each inlet 5, a set of cable guide brackets 16 are provided. Each set of cable guide brackets 16 includes multiple spaced arc-shaped guide plates 161, which form an arc-shaped cable routing channel. At least one arc-shaped guide plate 161 is provided with a limiting pressure plate 162 to restrict the axial movement of the optical cable 3, preventing the optical cable 3 from detaching from the arc-shaped cable routing channel. In use, when the fiber optic connector 31 is pulled out from the inlet 5, the optical cable 3 is confined within the cable guide bracket 16, achieving orderly cabling and preventing bending.

[0040] The base 11 has a fixing slot 15 on its edge, which is used to secure the fiber optic adapter 32 to the edge of the base 11 after construction, so that the cable storage box can be directly converted into an externally open communication interface panel. The base 11 also has a receiving groove 14 inside, which is used to securely store the fiber optic connector 31 in the factory and in the non-use state to prevent shaking.

[0041] See Figure 5 and Figure 7 As shown, in this embodiment, the cable storage reel 2 consists of an upper disc 21, a lower disc 22, and a winding post 23 between them. The optical cable 3 is wound around the winding post 23, which has a circular hole axially formed at its center. The inner wall of the circular hole protrudes radially inward to form an annular boss 231. The cable storage reel 2 is fitted onto the outside of the support post 13 of the base 11 through the circular hole of the winding post 23, and is engaged with the elastic buckle 132 on the support post 13 by the annular boss 231.

[0042] Specifically, the elastic buckle 132 is a cantilever elastic claw structure that extends integrally along the side wall of the support column 13. The support column 13 on both sides of the elastic buckle 132 has axially penetrating elastic deformation grooves. The elastic buckle 132 has a guide slope on its top outer side and a horizontal locking step surface at its bottom. The annular boss 231 also has chamfers at its top and bottom corresponding to the guide slope. During assembly, the cable storage tray 2 is pressed into the support column 13 from top to bottom. The annular boss 231 presses against the guide slope at the top of the elastic buckle 132, causing the elastic buckle 132 to elastically retract and deflect towards the hollow inner side of the support column 13. After passing the annular boss 231, it elastically resets and is blocked by the horizontal locking step surface. This allows the cable storage tray 2 to rotate freely around its axis within the base 11, but it cannot detach axially.

[0043] The upper disc 21 has a follower groove 24 on its surface. The fiber optic adapter 32 is inserted into the follower groove 24. When the optical cable 3 is pulled out, the fiber optic adapter 32 rotates in sync with the cable storage disc 2, effectively preventing the optical fiber from twisting.

[0044] Furthermore, the upper disc 21 has multiple optical cable guide ears 26 arranged radially on its surface. Each optical cable guide ear 26 has an optical cable guide groove 261, and the top of the optical cable guide ear 26 protrudes from the surface of the upper disc 21 for storing and limiting the optical cable 3. The radially protruding optical cable guide ears 26 enable independent partitioning and splicing management of multiple optical cable segments 3, preventing excessive bending or tangling of the optical cables 3 in the disc due to interlayer compression, thus improving the neatness of the wiring in the disc and the smoothness of subsequent cable pulling. At the same time, the upward protrusion of the optical cable guide ears 26 can also be used as levers for manual rotation of the cable storage disc 2 by construction personnel when manual retrieval or fine adjustment of the length of the optical cable 3 is required.

[0045] See Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the locking knob 4 is located at the top center of the cable storage tray 2 and has a cylindrical structure. Its top surface has an upward-protruding grip handle, and the surface is engraved with status indicators 43, including: an unlocked status indicator (UNLOCK), a locked status indicator (LOCK), and a rotating arrow corresponding to the switching direction. At least one limiting post 42 protrudes radially outward from its cylindrical sidewall, preferably two symmetrically arranged. Its bottom end face has a locking tooth 41 that matches the limiting gear 131 on the support column 13 of the base 11. Furthermore, both the free ends of the tooth tips of the locking teeth 41 and the limiting gear 131 are chamfered with symmetrical guide angles or wedge-shaped bevels, or the tooth profile is involute / trapezoidal. When the locking knob 4 sinks axially, if the circumferential phase of the locking teeth 41 and the limiting gear 131 is not completely aligned, the guide angles at the top of the locking teeth 41 and the limiting gear 131 will contact and generate a small circumferential component force, forcing the locking knob 4 and the cable storage disc 2 to make slight circumferential adaptive adjustments to align, ensuring that the locking teeth 41 can smoothly slide into the tooth groove and mesh tightly, preventing rigid tooth ejection. By setting an intuitive status indicator 43 on the top surface of the locking knob 4, clear and explicit human-machine interaction visual guidance is provided for users and construction personnel to switch between unlocking and locking states.

[0046] In the actual design, the winding post 23 passes through the upper disk 21 and extends beyond the end of the upper disk 21. A stepped limiting groove 25, which mates with the limiting post 42, is formed along the circumference. This stepped limiting groove 25 has a significant height difference structure, specifically divided into: High-level support platform 251: Located at a higher level, its surface is a flat support surface; Low-position slot 252: Located at a lower horizontal level and having a vertical lateral limiting wall, forming a recessed slot area; Transition slide: Connecting the high-position support platform 251 and the low-position slot 252, it provides a smooth transition path for the lifting and lowering of the limit column 42.

[0047] Furthermore, the surface of the high-level support platform 251 is provided with a stop protrusion 253 to prevent the limiting post 42 from sliding from the high-level support platform 251 into the low-level slot 252 when the cable storage reel 2 rotates. The stop protrusion 253 physically limits the limiting post 42, effectively preventing the unexpected interruption and locking caused by the limiting post 42 accidentally sliding back into the low-level slot 252 due to vibration or inertia when the cable storage reel 2 rotates due to the pulling of the optical cable 3 in the unlocked state.

[0048] In this embodiment, the following working state switching logic is included: UNLOCK / Unlock Cable Pulling Status: The operator grips the handle and rotates the locking knob 4 in the direction of the "UNLOCK" arrow. During this rotation, the limiting post 42 on the side wall of the locking knob 4 moves along the trajectory of the limiting slide groove 25 and crosses the high support platform 251. Due to the elevation effect of the high support platform 251, the limiting post 42 is lifted, forcibly driving the locking knob 4 to rise axially and into a suspended state. At this time, the locking teeth 41 at the bottom of the locking knob 4 disengage axially from the limiting gear 131 on the support post 13 of the base 11, the cable storage tray 2 is released from interference with the base 11, and the cable storage tray 2 can rotate smoothly and freely for the construction to pull out the optical cable 3.

[0049] LOCK / Rigid Locking State: After the optical cable 3 is pulled to the predetermined length, the locking knob 4 is reversed in the direction of the "LOCK" arrow and pressed downwards. The limiting post 42 slides out from the high support platform 251 and falls into the low slot 252 along the transition slide. At this time, the locking knob 4 sinks axially. Due to the reduced height, the locking teeth 41 at the bottom of the locking knob 4 directly insert and tightly engage with the limiting gear 131 on the base 11.

[0050] Once locked, a two-dimensional physical fixation occurs: the limiting post 42 falls into the deep recessed low-position slot 252, and its lateral obstruction by the vertical wall of the low-position slot 252 causes the locking knob 4 and the cable storage reel 2 to form a relatively fixed engagement in the circumferential direction, preventing them from rotating relative to each other; the locking teeth 41 at the bottom of the locking knob 4 rigidly engage with the base 11, preventing the locking knob 4 itself from rotating relative to the base 11. Thus, the base 11, the locking knob 4, and the cable storage reel 2 form a rigid linkage and lock, making it difficult for the cable storage reel 2 to slip or retract even if the external optical cable 3 is pulled forcefully.

[0051] To more clearly illustrate the working principle of this invention, the circulation of the cable storage box is divided into four steps based on practical application scenarios: Step 1: Factory and shipping condition, for shock protection. See also... Figure 2As shown, firstly, the optical cable 3 is neatly wound onto the winding post 23 of the cable storage reel 2. Then, the fiber optic adapter 32 connected to one end of the optical cable 3 is secured in the follower groove 24 of the disc 21 on the cable storage reel 2, and the fiber optic connector 31 connected to the other end of the optical cable 3 is secured in the receiving groove 14 inside the base 11. Finally, the locking knob 4 is in the depressed "LOCK" position, the locking teeth 41 and the limit gear 131 are fully engaged, the cable storage reel 2 is locked and cannot rotate, ensuring that the cable does not unravel during transportation.

[0052] Step Two: On-site fixed-length pull-out, used for unlocking and follow-up. See also Figure 8 As shown, first, the construction worker opens the top cover 12, separating it from the base 11 to expose the cable storage tray 2. Next, the fiber optic connector 31 is removed from the receiving slot 14 inside the base 11. Then, the locking knob 4 is pulled upwards axially, causing the bottom locking teeth 41 to completely disengage axially from the limiting gear 131. Next, the locking knob 4 is rotated in the direction of the "UNLOCK" arrow, forcing the limiting post 42 onto the high support platform 251 to maintain the unlocked state. Finally, the fiber optic connector 31 is pulled outwards along the cable guide bracket 16 and the cable inlet 5 towards the building's low-voltage electrical box.

[0053] During this process, the cable storage reel 2 smoothly rotates to release the optical cable 3, while the optical fiber adapter 32, which is stuck in the follower slot 24, rotates steadily coaxially with the reel without any relative torsion.

[0054] Step 3: Length locking and station transfer to achieve panel forming. After the optical cable 3 is pulled out to the required length, reverse the locking knob 4 and press it down to the "LOCK" position. The locking teeth 41 and the limiting gear 131 rigidly engage, and the cable storage reel 2 locks instantly. If the cable is pulled out too far, the optical cable guide ear 26 on the cable storage reel 2 can be turned in the opposite direction to rotate the cable storage reel 2 to retract the excess cable before locking it.

[0055] Workstation transfer operation: See Figure 9 As shown, the construction worker pulls the fiber optic adapter 32, which has been moving along the cable storage tray 2, out of the follower slot 24. At this time, because the tail end of the fiber optic adapter 32 has a pre-reserved arc-shaped bending compensation margin to adapt to the work position span transfer, when the cable storage tray 2 is in a rigid locked and non-rotatable state, this bending compensation margin allows the fiber optic adapter 32 to cross the edge of the cable storage tray 2 and extend to the edge of the base 11 without causing excessive stretching or axial breakage of the micro-fiber; then, the construction worker arranges the remaining fiber optic cable along the guide limiting channel near the fixed slot 15 in the base 11, and finally firmly inserts the fiber optic adapter 32 into the fixed slot 15 and fastens the top cover 12.

[0056] Step 4: Terminal access for plug-and-play functionality. At this point, the cable storage box has been transformed into a wall-mounted fiber optic information panel. Users only need to use a standard fiber optic patch cord, plugging one end into the optical modem / router and the other end directly into the fiber optic adapter 32 that was just fixed to the edge of the cable storage box, to complete the deployment of the in-home communication link.

[0057] The beneficial effects of this invention are: (1) Solving the problem of cable twisting: The two-stage cabling station design of the inner connector, which is "on-board follow-up storage + post-construction transfer and fixation", makes the inner connector and the tray rotate coaxially and at the same frequency when pulling the optical cable 3 over a long distance, which greatly reduces the risk of twisting and breaking of the micro optical fiber from a physical kinematics perspective.

[0058] (2) Rigid anti-rebound locking, intuitive operation: It adopts an end face gear meshing transmission mechanism of lifting to unlock and pressing to lock. The operation feel is clear, with a segmented feeling of falling into the tooth groove, and the anti-torsional force provided by the gear meshing is extremely large. Even if the external optical cable 3 is pulled with great force, it can effectively prevent the slippage or retraction of the coil that is common in traditional friction damping structures.

[0059] (3) Highly integrated socket experience: After the construction is completed, the internal connectors are transferred to the edge fixing slot 15. This allows the cable storage box, which was originally just a cable container, to be directly upgraded to a "standard fiber optic information panel" on the wall after the cable is fixed in length, thus improving the interface compatibility and standardization.
