Description

Technical Field

[0001] This utility model belongs to the field of optical communication equipment technology, and in particular relates to an optical splitter box. Background Technology

[0002] Optical splitter boxes are critical passive components in optical communication networks, primarily used for protective connections, cabling, and optical signal distribution and scheduling of fiber optic links. They typically integrate precision optical components such as optical splitters, fiber optic fusion splices, and adapters. The performance and stability of these components directly affect the transmission quality and reliability of the entire optical communication network. Therefore, to ensure that the internal optical components are unaffected by the external environment, optical splitter boxes must possess long-term, stable, and efficient sealing performance to maintain a highly clean working environment inside the box.

[0003] However, existing optical splitter boxes generally have structural design flaws, especially at the fiber optic cable or fiber optic cable entry ports, where the sealing structure is often quite simple. Traditional sealing methods mostly rely on passive sealing means such as rubber sealing rings, sealing strips, or mechanical clamping components. These structures may provide some sealing effect during initial installation, but during long-term use, the seals are prone to elastic failure, cracking, or deformation due to the combined effects of periodic changes in ambient temperature, diurnal temperature differences, mechanical vibration, and material aging. This results in tiny gaps between the seals and the box body and optical fiber. Fine particles such as dust, moisture, and sand can then penetrate into the box through these gaps.

[0004] Once contaminants adhere to the fiber endface or the surface of optical components such as optical splitters, they can cause significant optical signal loss and increased reflection, severely degrading signal transmission quality and potentially leading to communication interruptions. Furthermore, moisture intrusion accelerates corrosion of metal components and damages optical devices, shortening the overall lifespan of the equipment and increasing network operation and maintenance costs and failure risks. Therefore, a crucial technical challenge for those skilled in the art is overcoming the poor environmental adaptability and unreliable long-term sealing performance of existing optical splitter boxes due to their passive sealing structure. The goal is to provide an optical splitter box that actively and effectively prevents external impurities from entering, ensuring the long-term stable operation of the optical components within the box, thereby significantly reducing signal loss and improving transmission quality. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned shortcomings and provide an optical splitter box.

[0006] An optical splitter box includes a box body, wherein at least one compression injection mechanism is provided inside the box body, the compression injection mechanism comprising:

[0007] The injection chamber is detachably installed inside the housing;

[0008] A plurality of injection slots are provided on the injection seat for inserting optical fibers;

[0009] A sensor module, disposed within the injection groove, is used to generate a detection signal indicating whether an optical fiber passes through the injection groove; and

[0010] A sealing assembly for sealing the injection tank, the sealing assembly including an injection probe and a filler area storing filler material;

[0011] The compression injection mechanism also includes a switch controller, which is connected to the sensor module and the sealing assembly. The switch controller can drive the injection probe to compress the filler in the filler area based on the detection signal, and inject the filler into the gap between the injection groove and the optical fiber through the injection probe to achieve sealing.

[0012] Furthermore, a switch plate consisting of two symmetrical switch sub-plates is provided at one end of the injection groove opening; an arc-shaped pressure plate is also provided inside the injection groove, one end of the arc-shaped pressure plate is connected to the filling material area, and the other end is connected to the switch plate; the switch controller is also used to control the switch plate to squeeze the filling material area through the arc-shaped pressure plate when the two switch sub-plates of the switch plate move closer to each other and retract.

[0013] Furthermore, an inlet is provided on the outer wall of the injection tank, and the inlet is connected to the filling material area for replenishing the filling material area.

[0014] Furthermore, the housing also includes an adapter mechanism; the adapter mechanism includes an adapter base, which is detachably snapped into the housing, and the adapter base has several adapter ports.

[0015] Furthermore, the outer wall of the optical splitter box is provided with a through hole, the position of which is aligned with the port axis of the injection groove and the adapter port to allow optical fiber to pass through.

[0016] Furthermore, the housing is provided with a fixing mechanism for fixing the optical splitter, the fixing mechanism including a carrier plate, and the optical splitter is disposed on the carrier plate.

[0017] Furthermore, the fixing mechanism also includes a slide block that is slidably connected to the inner wall of the box, a slide plate is connected to the slide block, and the support plate is elastically connected to the slide plate by a spring disposed between the support plate and the slide plate.

[0020] Furthermore, a splice tray for splicing the trunk optical fiber and the pigtail is fixedly installed inside the box.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides an optical splitter box that, through a pressure injection mechanism, allows the sensor module to instantly and accurately detect the presence of an external optical fiber as it passes through the injection groove. This triggers a switch controller, which in turn drives the injection probe to precisely inject filler into the tiny gap between the optical fiber and the injection groove wall. This creates a customized sealing layer that perfectly adheres to the optical fiber surface without any gaps, resulting in sealing performance far superior to traditional rubber seals that rely on pre-fabricated dimensions and elasticity. It fundamentally solves the technical pain points of traditional passive sealing structures, which suffer from decreased elasticity, deformation, cracking, and eventual seal failure due to material aging, environmental temperature changes, and mechanical vibration. By actively isolating the intrusion paths of external dust, moisture, and particulate matter, it effectively protects the cleanliness of precision optical components such as the optical splitter inside the box, thereby significantly reducing optical signal loss caused by contaminants. This greatly improves the transmission quality of optical communication and the long-term stability of network operation, and effectively extends the service life of the equipment.

[0035] This embodiment provides an optical splitter box 100. Please refer to [link / reference]. Figure 1 and Figure 2 The main body is a housing 110. At least one compression injection mechanism 120 is provided inside the housing 110; in this embodiment, one set is provided at each end. This compression injection mechanism 120 is used to achieve active and intelligent sealing during optical fiber introduction. Specifically, the compression injection mechanism 120 includes an injection seat 121 detachably installed inside the housing 110; the detachable connection facilitates subsequent maintenance or modular replacement.

[0036] Please refer to the following: Figures 3 to 6 The injection seat 121 has one or more cylindrical injection grooves 122 for external optical fibers to pass through the housing 110. On the inner wall of each injection groove 122, a sensor module (not individually labeled in the figure, its function is represented by the switch controller 127) and a sealing assembly are arranged in a ring. The sensor module is used to detect in real time whether an optical fiber passes through the injection groove 122 and generate a corresponding detection signal. The sealing assembly includes multiple injection probes 124 evenly distributed along the inner wall circumferentially, and a filling material area 126 associated with the function of the injection probes 124 (e.g., ...). Figure 7 As shown), the filler area 126 is pre-stored with fluid sealing filler such as self-healing gel.

[0037] The compression injection mechanism 120 also includes a switch controller 127 disposed on the inner wall of the injection tank 122. The signal input terminal of the switch controller 127 is electrically connected to the sensor module, and the signal output terminal is electrically connected to the injection probe 124. Its working logic is as follows: when the sensor module detects the insertion of the optical fiber, the switch controller 127 receives a signal and then drives the injection probe 124 to compress the filling material area 126, so that the filling material is injected into the inner cavity of the injection tank 122 through the nozzle of the injection probe 124, thereby filling and sealing all the gaps between the optical fiber and the inner wall of the injection tank 122.

[0038] In some specific embodiments, a sensor module is provided in a ring around the inner wall of the injection groove 122, wherein the sensor module specifically includes:

[0039] The photoelectric beam sensor transmits an infrared beam through the injection tank 122. When the injection tank 122 passes through an optical fiber, the optical fiber blocks the light, triggering a change in light intensity. The ultrasonic sensor emits ultrasonic waves inside the injection tank 122. When the injection tank 122 passes through an optical fiber, the optical fiber blocks the echo, causing a delay or attenuation in the echo. The fiber Bragg grating is located on the switch plate 1221. When the switch plate 1221 is squeezed by the optical fiber, it causes micro-strain in the optical fiber, resulting in a wavelength shift of the FBG.

[0040] The sensor module detects whether there is an optical fiber passing through the injection tank 122 and sends the signal to the switch controller 127. Based on the signal from the sensor module, the switch controller 127 issues a control command to control the switch board 1221 to open, allowing the optical fiber to pass through, and starts the injection probe 124 to fill the gap between the optical fiber and the injection tank 122.

[0041] In some specific embodiments, the injection probe 124 is equipped with a time delay relay. By setting a time delay threshold, the injection probe 124 is activated to fill the gap only after the optical fiber has stabilized inside the optical splitter box 100 after passing through the through hole 140 of the switch board 1221.

[0042] More specifically, a control panel is provided on the outer wall of the optical splitter box 100. The control panel is communicatively connected to the pressure injection mechanism 120. The pressure injection mechanism 120 can be remotely controlled through the control panel, thereby enabling manual control of the opening and closing of the injection probe 124.

[0043] In some embodiments, an anti-interference mechanism is integrated inside the optical splitter box 100. Specifically, the anti-interference mechanism includes: a heat preservation module, comprising a temperature sensor arrayed along the inner wall of the splitter box to detect the internal temperature of the optical splitter box 100; a thermoelectric cooler, which activates to cool the interior of the optical splitter box 100 when the temperature sensor detects that the internal temperature exceeds a threshold, preventing damage to the internal optical fiber due to excessively high or low temperatures; a humidity control module, comprising a humidity sensor to monitor the humidity inside the optical splitter box 100; a semiconductor dehumidification module, comprising a TEC plate and condenser fins; and an ultrasonic humidifier, comprising a T-piezoelectric ceramic atomizing plate.

[0044] The humidity sensor detects the humidity inside the optical splitter box 100. When the internal humidity exceeds the threshold, the semiconductor dehumidification module and ultrasonic humidifier are activated to keep the humidity inside the optical splitter 155 within a reasonable range, thus avoiding problems such as cracking or mold growth of the optical fiber gel caused by excessively high or low internal humidity.

[0045] In some embodiments, to improve the anti-interference capability of the optical splitter box 100, the optical splitter box 100 adopts a metallized sealed box body 110. The box body 110 is made of aluminum alloy and is covered with a micro-arc oxidation coating and an anti-corrosion coating. The micro-arc oxidation coating blocks water vapor penetration, and the anti-corrosion coating reduces rust problems.

[0046] In some embodiments, to improve dustproof performance, an air pump is installed inside the optical splitter box 100. The air pump stores inert gas, specifically including: nitrogen (cost-effective and effective dustproof); krypton (used for ultra-high reliability scenarios; large molecules, low leakage rate); and helium (limited to special heat dissipation needs; requires high-level sealing). Specifically, when the optical splitter box 100 is in operation, the air pump is activated to expel the inert gas, increasing the internal pressure of the optical splitter box 100 and preventing external dust, sand, fine particles, and other impurities from entering the optical splitter box 100 through gaps.

[0047] In some embodiments, a sealing plate is provided in the inner cavity of the optical splitter box 100, wherein the sealing plate is consistent with the outline of the optical splitter box 100 and the sealing plate is detachably connected to the outer wall of the optical splitter box 100.

[0048] Based on the above embodiments, please refer to Figure 5 and Figure 7 At the opening of the injection tank 122 near the interior of the housing 110, there is a switch plate 1221 consisting of two symmetrical semi-circular switch sub-plates. Inside the cavity of the injection tank 122, there is a hollow, flexible arc-shaped pressure plate 125 and a filling material area 126. One end of the arc-shaped pressure plate 125 (the end near the injection probe 124) is connected to the filling material area 126, and the other end is connected to the switch plate 1221. The switch controller 127 controls not only the injection probe 124 but also the switch plate 1221. When optical fiber insertion is detected, the switch controller 127 drives the two switch sub-plates of the switch plate 1221 to move closer together and retract. Due to the connection between the switch plate 1221 and the arc-shaped pressure plate 125, the retraction of the switch plate 1221 drives and squeezes the arc-shaped pressure plate 125, thereby applying pressure to the internal filling material area 126. Combined with the activation of the injection probe 124, this completes the injection of the filling material.

[0049] More specifically, the arc-shaped pressure plate 125 and the filling area 126 have the same shape as the inner contour of the injection groove 122, and the two ends of the arc-shaped pressure plate 125 are respectively connected to the switch plate 1221 and the filling area 126.

[0050] When the switch plate 1221 is in the working state, that is, when the injection tank 122 is connected to the main optical fiber, the switch plate 1221 is in the conducting state. The switch plates 1221 on both sides retract into the inner cavity of the injection tank 122. Since the switch plate 1221 is connected to the arc-shaped pressure plate 125 in the inner cavity of the injection tank 122, the arc-shaped pressure plate 125 is squeezed by the contraction of the switch plate 1221, which drives the arc-shaped pressure plate 125 to squeeze the filler in the filling area 126 to the injection probe 124. When the switch plate 1221 is in the standby state, that is, when there is no main optical fiber in the injection tank 122, the arc-shaped pressure plate 125 is in the stationary state.

[0051] In this embodiment, the material of the filler area 126 includes a self-healing gel, specifically a silicone-polyurethane hybrid gel. Compared with the problem of hardening, cracking and permanent deformation of traditional rubber seals at -25℃ to 70℃, the self-healing gel can maintain its elasticity even in complex environments of high and low temperatures. It can still maintain its elasticity at -80℃ to 200℃, allowing for multiple cycles of insertion and removal. Moreover, its sealing performance is significantly improved compared to traditional rubber seals.

[0052] Furthermore, for convenient replenishment of filler material in filler area 126, please refer to [link / reference needed]. Figure 4 and Figure 6One or more feed ports 123 are provided on the outer wall of the injection tank 122. These feed ports 123 are interconnected with the filling area 126 through internal pipes. During production or maintenance, sealing filler can be injected or replenished into the filling area 126 through the feed ports 123 using special tools, ensuring the continuous usability of the device.

[0053] In some specific embodiments, a plurality of feed ports 123 are provided along the outer wall of the injection groove 122. The passage of the optical fiber inside the injection groove 122 is detected by a sensor module, and the signal result is sent to the switch controller 127. The switch controller 127 activates the injection probe 124, which compresses the filler and causes the filler to be ejected from the injection probe 124 to fill the gap between the injection groove 122 and the optical fiber, preventing external impurities from entering the optical splitter box 100 through the gap and forming a sealed environment.

[0054] Please refer to it again. Figure 1 and Figure 2 In addition to the injection molding mechanism 120, the optical splitter box 100 also includes an adapter mechanism 130 for fiber optic connections inside its housing 110. This adapter mechanism 130 includes one or more adapter sockets 131, which are detachably snapped onto the inner wall or frame of the housing 110, facilitating the installation of different types or numbers of adapters as needed. Each adapter socket 131 has several adapter ports 132 fixedly installed for the insertion of fiber optic connectors.

[0055] In some specific embodiments, the adapter socket 131 includes an input adapter socket 131 and an output adapter socket 131, wherein both the input adapter socket 131 and the output adapter socket 131 are provided with a plurality of adapter boards, and the adapter boards are provided with a plurality of adapter ports 132; a pigtail (user-side pigtail) is connected to the back of the output adapter socket 131. The adapter socket 131 includes an adapter board containing various types of adapter ports 132.

[0056] To ensure that the external optical fiber can be smoothly inserted into the housing 110 and mate with the internal adapter port 132, please refer to [link / reference needed]. Figure 2 At both ends of the housing 110, through holes 140 are provided, corresponding to the positions of the internal components. Specifically, the position of each through hole 140 is precisely aligned with the central axis of an injection groove 122 and the port axis of an adapter port 132, forming a straight channel. This ensures that the optical fiber can pass unimpeded through the pressure injection mechanism 120 and be accurately aligned with the adapter port 132 during insertion.

[0057] Please see Figure 1 and Figure 8The core working unit inside the housing 110 is the optical splitter 155. To securely and shock-absorbingly fix it, a fixing mechanism 150 is provided inside the housing 110. This fixing mechanism 150 includes a support plate 151 for directly mounting the optical splitter 155. The optical splitter 155 is fixedly mounted on the upper surface of the support plate 151 by means of clips or screws.

[0058] In this embodiment, the optical splitter 155 can adopt an integrated module instead of a single chip socket, specifically including: a thermally conductive substrate module for providing heat dissipation and mechanical support, wherein the thermally conductive substrate module includes: a metal substrate: the metal substrate is made of copper-tungsten alloy; a microfluidic structure: a serpentine copper tube is used to increase the heat dissipation area; a positioning and calibration module: submicron-level precision alignment is adopted, and a six-degree-of-freedom adjustment stage is integrated on the carrier plate 151, wherein the six-degree-of-freedom adjustment stage is driven by a piezoelectric ceramic actuator; a visual alignment module: a CCD camera is provided on the carrier plate 151, and infrared positioning marks are made by the CCD camera; a stress buffer module: used to suppress vibration / thermal stress impact; a magnetic levitation module: including a neodymium magnetic ring array; and a locking mechanism module: to prevent displacement and loosening.

[0059] For details on achieving a flexible connection and buffered fixation of the support plate 151, please refer to [link / reference needed]. Figure 8 The fixing mechanism 150 also includes a slide block 152 that is slidably connected along a guide rail (not shown) on the inner wall of the housing 110. A slide plate 153 is fixedly connected to the slide block 152. A support plate 151 is located above the slide plate 153 and is elastically connected to it by a plurality of springs 154 disposed between the two. When the optical splitter housing 100 is subjected to external vibration or impact, the springs 154 can effectively absorb energy, play a buffering role, and protect the optical splitter 155 from damage.

[0060] In some specific embodiments, a piezoelectric ceramic-driven clamping mechanism is provided on the support plate 151, specifically including a piezoelectric ceramic stack, a telescopic spring 154, and contact components; wherein the contact components include: a clamping head, which is made of zirconia ceramic with a hardness of 1200 HV and a thermal conductivity of 2.5 W / mK; a thermally conductive pad, which is made of graphene composite pad with a thermal conductivity of 150 W / mK and a compression ratio of 20%; and an insulating layer, which is made of polyimide film with a dielectric strength of 300 kV / mm and a CTE of 3 ppm / ℃.

[0061] In some specific embodiments, a sensing unit is integrated into the clamping mechanism, specifically including:

[0062] The system includes a strain gauge sensor, in which a metal foil strain gauge is attached to the contact surface of the contact component and the optical splitter 155; a pressure sensor, used to monitor the clamping force between the contact component and the optical splitter 155, wherein the clamping force safety threshold is ≤15N to prevent micro-cracks from appearing in the optical splitter 155, and the minimum clamping force is >5N (for vibration resistance requirements), with a force distribution uniformity of ≤10% pressure difference on the chip surface; a capacitive displacement sensor, used for differential measurement of parallel plates; and a temperature sensor, used to monitor the temperature between the contact component and the optical splitter 155.

[0063] Please see Figure 1 and Figure 9 To neatly store redundant optical fibers or patch cords inside the housing 110, at least one spool 160 for storing optical fibers is rotatably installed inside the housing 110. The spool 160 is mounted on a bracket on the inner wall of the housing 110 and can rotate freely, making it easy for users to wind or remove optical fibers, effectively managing internal cabling and avoiding excessive bending and tangling of optical fibers.

[0064] In some specific embodiments, the bottom of the drum 160 is connected to the drive motor via a bearing. The drive motor drives the drum 160 to rotate via the bearing, thereby automatically storing the optical fiber and reducing the space occupied by the optical fiber.

[0065] For better management of the multiple different optical fibers wound on spool 160, please refer to Figure 9 On the body of the spool 160, multiple disc-shaped limiting rings 161 are spaced apart along its axial direction. These limiting rings 161 divide the entire winding area of ​​the spool 160 into several independent slots, allowing users to wind different optical fibers into different slots, thereby effectively separating different optical fibers and preventing them from crossing, tangling, or getting mixed up during storage and use.

[0066] Please refer to it again. Figure 1 To facilitate the connection between the trunk fiber and the pigtails within the box, a fusion splice tray 170 is also fixedly installed inside the box 110 for splicing optical fibers. The fusion splice tray 170 is typically a stacked structure, providing dedicated slots for fiber core placement and heat shrink tubing fixing positions. It provides a safe and standardized splicing operation platform and protective space for the entry end of the trunk fiber and the pigtails connected to the adapter port 132 or the optical splitter 155.

[0067] In some specific embodiments, a ventilation array is provided on the outer wall of the optical splitter box 100, and a heat dissipation fan adapted to the ventilation array is provided inside the optical splitter box 100. A filter screen is provided in the ventilation opening to prevent external dust and impurities from entering the interior of the optical splitter box 100.

[0068] Based on the above embodiments, the working principle of this utility model is as follows:

[0069] The main optical fiber is led out from the OLT room. After the coating is stripped off, the main optical fiber passes through the through hole 140 on the outer wall of the optical splitter box 100 and reaches the injection tank 122. The position of the main optical fiber is detected by the sensor module arranged in a ring on the inner wall of the injection tank 122. When the main optical fiber squeezes the switch plate 1221, the switch plate 1221 and the injection probe 124 are turned on by the switch controller 127.

[0070] Under the action of the switch controller 127, the switch plate 1221 contracts into the inner cavity of the injection tank 122, thereby squeezing the filler in the filling area 126 to the vicinity of the injection probe 124, and spraying the filler out through the injection probe 124 to fill and seal the gap between the injection tank 122 and the main optical fiber.

[0071] The main optical fiber enters the optical splitter box 100, and the main optical fiber is fused with the pigtail (bare fiber end) on the fusion splice tray 170 at high temperature to extend a pigtail with a connector. The SC / APC connector of the pigtail is connected to the input port of the optical splitter 155 on the carrier board 151 through the adapter port 132 on the input adapter board.

[0072] According to actual needs, the position of the carrier plate 151 is adjusted along the XY axis by sliding block 152, thereby changing the position of optical splitter 155. After adjustment, the optical splitter 155 splits the light and outputs the light. Multiple output ports are led out to the front adapter port 132 of the output adapter board through short jumper wires, and the wiring pigtail is led out from the adapter port 132 on the back of the output adapter panel.

[0073] The pigtail is fused to the optical fiber in another set of fusion splice trays 170 to extend the pigtail. The pigtail is wound on the drum 160, and multiple pigtails are stored and organized by the limiting ring 161 on the drum 160 to reduce its space occupation.

[0074] The neatly organized pigtails are connected to the user end through the through-hole 140 on the outer wall of the optical splitter box 100.

[0075] For those skilled in the art, other variations or modifications can be made based on the above description.
