Description

Technical Field

[0001] This utility model relates to the technical field of optical cable splitting devices, specifically a fiber splitting box with a sealing function. Background Technology

[0002] A fiber distribution box is a device used in fiber optic communication networks to manage and distribute fiber optic lines. It is typically installed inside or outside buildings, or in specific facilities such as basements or telecommunications equipment rooms, serving as a terminal box for fiber optic cable entry points or other connection points, connecting the backbone fiber optic cable and the user-end fiber optic cable.

[0003] Existing fiber distribution box designs, such as the corridor fiber distribution box disclosed in Chinese invention patent (application publication number: CN105607200A), introduce an innovative corridor fiber distribution box that solves the problem of fixed and non-adjustable fiber distribution quantity in traditional fiber distribution devices. This corridor fiber distribution box includes: a box body with a channel for optical cables to pass through; a box cover detachably connected to the box body and enclosing it to form a receiving cavity; and splice trays, with multiple splice trays stacked within the receiving cavity. The bottom splice tray is fixedly connected to the box body, and adjacent splice trays are detachably connected in one manner, ensuring that the optical fibers in the cable can be output after splicing within the splice tray. This design allows for adjustment of the fiber distribution quantity as needed, improving flexibility and adaptability.

[0004] However, the fiber distribution box was not designed with waterproofing in mind, which may limit its use in humid environments or underwater conditions. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a fiber distribution box with a sealing function in light of the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a fiber distribution box with sealing function is proposed, including: an outer box body;

[0007] The outer box cover is rotatably connected to the outer box body;

[0008] An elastic sealing element, made of a single-component silicone gel, is disposed between the outer casing and the outer cover to form a sealed cavity between them. The elastic sealing element has multiple spaced-apart slots.

[0009] The slot can be enlarged as the optical fiber line passes through it. The enlarged slot is adapted to the shape of the optical fiber line and hugs the outside of the optical fiber line to provide a seal for the cavity.

[0010] In the aforementioned fiber distribution box with sealing function, the outer wall of the outer box body extends outward to form multiple studs and multiple buckles. The outer box cover is provided with hollow bosses corresponding to the studs and latches corresponding to the buckles. The latches are provided with latch grooves. The buckles are movably engaged with the latch grooves. Bolts pass through the hollow bosses and are connected to the studs to fix the outer box body and the outer box cover and compress the sealing element.

[0011] In the aforementioned fiber distribution box with sealing function, the elastic seal includes a main sealing part and a pressing part. The insertion slot is disposed on the main sealing part and is disposed opposite to the pressing part, so that when the fiber distribution box is closed, the pressing part presses against the outer wall of the optical fiber line and generates elastic deformation.

[0012] In the aforementioned fiber distribution box with sealing function, a first mounting groove is formed around the outer box body in the circumferential direction, the main sealing part is disposed in the first mounting groove, a second mounting groove is disposed on the outer box cover, and the pressing part is disposed in the second mounting groove.

[0013] In the aforementioned fiber distribution box with sealing function, a rotating seat is provided at the end of the outer box body away from the insertion slot, and a rotating column is provided on the outer box cover, the rotating column being movably inserted into the rotating seat.

[0014] In the aforementioned fiber distribution box with sealing function, a limiting protrusion is provided on the outer side of the rotating seat. The limiting protrusion moves against the outer side wall of the outer box cover. When the outer box cover rotates relative to the outer box body to open the fiber distribution box, the limiting protrusion is used to limit the outer box cover.

[0015] The aforementioned fiber distribution box with sealing function further includes an inner box body and an inner box cover. The inner box body is detachably connected to the outer box body, and the inner box cover is rotatably connected to the inner box body. The inner box cover is provided with a limiting post, and the inner box body is provided with a first limiting hole and a second limiting hole. The inner box cover has a closed position and a maximum open position.

[0016] When the inner box cover and the inner box body are in the closed position, the limiting post is inserted into the first limiting hole;

[0017] When the inner box cover is in the maximum open position, the limiting post is inserted into the second limiting hole.

[0018] In the aforementioned fiber distribution box with sealing function, a welding groove is provided in the inner box body. The welding groove extends from the bottom wall of the inner box body towards the inner box cover to stack welding pipes.

[0019] In the aforementioned fiber distribution box with a sealing function, both the inner box and the outer box are provided with binding support parts for cable ties to bind the optical fiber lines.

[0020] In the aforementioned fiber distribution box with sealing function, both the inner box body and the inner box cover are provided with wire blocking parts.

[0021] Compared to existing technologies, the advantage of this invention lies in its ability to provide an effective seal between the outer casing and the outer cover through an elastic seal made of single-component silicone gel. This allows the fiber distribution box to be used not only in conventional environments but also in deep-water environments, ensuring that the internal components are not affected by external moisture.

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1 to 5 As shown, a fiber distribution box with sealing function according to this utility model includes: an outer box body 100;

[0030] The outer box cover 200 is rotatably connected to the outer box body 100;

[0031] An elastic sealing element 300, made of a single-component silicone gel, is disposed between the outer box body 100 and the outer box cover 200. This elastic sealing element 300 forms a sealed cavity between the outer box body 100 and the outer box cover 200. The elastic sealing element 300 has multiple spaced-apart slots 311.

[0032] The slit 311 can be enlarged to accommodate the passage of the optical fiber line. The enlarged slit 311 is adapted to the shape of the optical fiber line and is held tightly to the outside of the optical fiber line to provide a seal for the cavity.

[0033] The outer box body 100 and the outer box cover 200 are preferably cubic in shape, but can also be cylindrical. Their four sides are designed with smooth transitions to improve the overall structure and aesthetics.

[0034] One-component silicone gel (1C or 1K silicone gel) is a room-temperature vulcanizing (RTV) sealant, primarily composed of silicone polymers such as polydimethylsiloxane. This type of silicone gel requires only one component to complete the curing process and typically begins to cure upon contact with moisture in the air. The cured silicone gel retains a degree of elasticity, allowing it to accommodate minor movements at the joints.

[0035] A resilient seal 300 made of single-component silicone gel, positioned between the outer casing 100 and the outer cover 200, provides an effective seal between the two. This allows the fiber distribution box to be used not only in conventional environments but also in deep-water environments, ensuring that the internal components are not affected by external moisture.

[0036] Furthermore, the elastic seal 300 is made of single-component silicone gel, which enables the spigot 311 to adapt to optical cable seals with diameters of 2 to 16 mm, meeting the fiber splitting requirements of different types of optical cables.

[0037] To facilitate the entry and exit of optical cables and split optical fibers into and out of the cavity, insertion slots 311 are provided on the elastic seal 300. These insertion slots 311 can be appropriately enlarged when the optical fiber passes through, and after insertion, they adapt to the shape of the optical fiber and fit tightly, thereby ensuring a sealing effect.

[0038] In one embodiment, the outer side wall of the outer box 100 extends outward to form a plurality of studs 110 and a plurality of snap fasteners 120. The outer box cover 200 is provided with hollow bosses 210 corresponding to the studs 110 and snap tongues 220 corresponding to the snap fasteners 120. The snap tongues 220 are provided with snap grooves 221. The snap fasteners 120 and snap grooves 221 are movably engaged. The bolts pass through the hollow bosses 210 and are connected to the studs 110 to fix the outer box 100 and the inner and outer box covers 200 and to compress the seal.

[0039] During installation, after fiber splitting, the optical cable and fiber are passed through the splice 311. First, the latch 220 on the outer cover 200 is aligned with the latch 120 on the outer housing 100, so that the slot 221 on the latch 220 fits onto the outside of the latch 120, completing the initial connection between the outer cover 200 and the outer housing 100. Next, the outer cover 200 and the outer housing 100 are further secured by passing one end of a bolt through the hollow boss 210 and screwing it into the stud 110. During this process, the elastic seal 300 deforms under force, tightly fitting against the outer wall of the optical cable and fiber, ensuring that the cavity is completely sealed.

[0040] In one embodiment, the elastic seal 300 includes a main sealing part 310 and a pressing part 320. The insertion slot 311 is disposed on the main sealing part 310 and is disposed opposite to the pressing part 320, so that when the fiber distribution box is closed, the pressing part 320 presses against the outer wall of the optical fiber line and generates elastic deformation.

[0041] Furthermore, the outer box 100 is provided with a first mounting groove 130 formed circumferentially around the outer box 100, the main sealing part 310 is disposed in the first mounting groove 130, the outer box cover 200 is provided with a second mounting groove 230, and the pressing part 320 is disposed in the second mounting groove 230. The first mounting groove 130 and the second mounting groove 230 are respectively used for the installation and fixation of the sealing part and the pressing part 320 on the outer box 100 and the outer box cover 200.

[0042] In one embodiment, a rotating seat 140 is provided at the end of the outer box 100 away from the slot 311, and a rotating post 240 is provided on the outer box cover 200. The rotating post 240 is movably inserted into the rotating seat 140. The rotating post 240 is movably inserted into the rotating seat 140 to realize the rotational connection between the outer box cover 200 and the outer box 100.

[0043] A limiting protrusion 141 is provided on the outer side of the rotating seat 140. The limiting protrusion 141 moves against the outer side wall of the outer box cover 200. When the outer box cover 200 rotates relative to the outer box body 100 to open the fiber distribution box, the limiting protrusion 141 is used to limit the outer box cover 200.

[0044] When the fiber separator box is opened to its maximum angle, the outer wall of the outer box cover 200 abuts against the limiting protrusion 141 to maintain the relative fixation between the outer box cover 200 and the outer box body 100. This ensures that the outer box cover 200 will not obstruct the fiber separation process during operation. Preferably, the opening angle range of the outer box cover 200 relative to the outer box body 100 is 0° to 150°. When the outer box cover 200 is opened to 150°, the limiting protrusion 141 abuts against the outer wall of the outer box cover 200.

[0045] In one embodiment, the solution further includes an inner box body 500 and an inner box cover 400. The inner box body 500 is detachably connected to the outer box body 100, and the inner box cover 400 is rotatably connected to the inner box body 500. The inner box cover 400 is provided with a limiting post 410, and the inner box body 500 is provided with a first limiting hole 510 and a second limiting hole 520. The inner box cover 400 has a closed position and a maximum open position. When the inner box cover 400 is in the closed position and abuts against the inner box body 500, the limiting post 410 is inserted into the first limiting hole 510. When the inner box cover 400 is in the maximum open position, the limiting post 410 is inserted into the second limiting hole 520.

[0046] The inner housing 500 and inner cover 400 are used to construct a double-layer structure inside the fiber distribution box to distinguish the entry and exit paths of the optical cables. Preferably, the inner housing 500 is used to house the optical cable entering from the splice 311, while the inner cover 400 is used to accommodate the optical fiber portion formed after fiber splitting. This design ensures that the optical cable and optical fiber do not interfere with each other, avoiding mutual influence, thereby making the wiring inside the fiber distribution box more rational and orderly.

[0047] The positioning post 410, the first positioning hole 510, and the second positioning hole 520 ensure that the inner box cover 400 remains fixed in both the closed and fully open positions. This means that when the inner box cover 400 is in the fully open position, it does not obstruct the fiber splitting operation; and when closed, the inner box cover 400 is firmly fixed to the inner box body 500, ensuring the overall stability of the fiber splitting box.

[0048] Preferably, the center lines of the first limiting hole 510, the second limiting hole 520, and the limiting post 410 are located on the same horizontal line. The purpose of this design is to ensure that the inner box cover 400 remains fixed when it is in the closed position or the maximum open position (i.e., after the inner box cover 400 has rotated 180° relative to the inner box body 500).

[0049] In one embodiment, a welding groove 530 is provided inside the inner box 500. The welding groove 530 extends from the bottom wall of the inner box 500 toward the inner box cover 400 to stack welding pipes.

[0050] The fusion splicing of optical fibers is specifically performed inside the fusion splice tube. Since one fusion splice tube is required for splicing one optical fiber, a fusion splice slot 530 is set up to secure multiple fusion splice tubes and allow multiple fusion splice tubes to be stacked. This can meet the needs of splicing multiple optical fibers at the same time and save horizontal space in the fiber distribution box.

[0051] In one embodiment, both the inner box 500 and the outer box 100 are provided with binding support parts 600 for binding fiber optic lines with cable ties, thereby making the fiber optic lines on the fiber distribution box more stable.

[0052] Preferably, both the inner box 500 and the inner box cover 400 are provided with wire blocking parts 700, so that the optical cable and optical fiber are fixed on the inner box 500 and the inner box cover 400 respectively, without interfering with each other.
