Description
Technical Field
[0001] The present invention belongs to the technical field of optical communications, and in particular relates to an optical fiber connector with high compatibility. Background Art
[0002] With the booming development of optical communications, fiber optic connectors, as key optical components, play a central role in the stable transmission of optical signals and are widely used in various optical communication systems and instruments. However, in the early days, their tail sleeve designs were rigid, adapting only to specific fibers. As applications expanded and different fiber specifications emerged, traditional tail sleeves were unable to adapt, resulting in unstable optical signal transmission. Recent research has introduced improvements such as elastic retaining rings, improving tail sleeve compatibility and alleviating adaptation issues.
[0003] However, when focusing on outdoor application scenarios, new problems arise one after another. The outdoor environment is complex and changeable, and harsh conditions such as wind, rain, and dust are common. This requires outdoor fiber optic connectors to have strong waterproof sealing capabilities, but the reality is not satisfactory. Existing outdoor fiber optic connectors have obvious shortcomings in the design of waterproof sealing structures: Currently, most waterproof sealing measures only focus on the inside of the fiber optic connector, such as the elastic gasket behind the inner core and the mechanical extrusion of the inner core and the metal body, in an attempt to prevent the intrusion of external moisture. However, in the key connection between the tail sleeve and the optical cable, there is no effective sealing structure, which allows impurities such as rain, dew, and dust to easily enter, greatly reducing the sealing reliability of existing outdoor fiber optic connectors and seriously threatening the stable operation of outdoor optical communication systems.
[0004] Therefore, a highly compatible optical fiber connector is proposed to solve the above problems. Summary of the Invention
[0005] In order to solve the problems raised in the above background technology, the present invention provides a fiber optic connector with high compatibility.
[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a highly compatible optical fiber connector, comprising a tail sleeve disposed outside an optical fiber, and further comprising: A flexible sealing body with elastic deformation capability is provided between the outer wall of the optical fiber and the inner wall of the tail sleeve, and has a cavity inside for accommodating gas; A positioning ring, fixed to the inner wall of the tail sleeve and in contact with the outer wall of the optical fiber, connected to the flexible sealing body and used to determine the position of the flexible sealing body in the tail sleeve; The pusher is coaxially arranged with the flexible sealing body and has one end in vertical contact with the flexible sealing body and the other end fixedly arranged inside the optical fiber connector; As the pushing member applies force to the flexible sealing body, the flexible sealing body is deformed by the force, and the gas inside the flexible sealing body is compressed to expand the flexible sealing body and fit tightly with the outer wall of the optical fiber and the inner wall of the tail sleeve.
[0007] In the above technical solution, preferably, the flexible sealing body includes: A first sealing ring and a second sealing ring fixedly mounted on both sides of the positioning ring and having elastic deformation capability; The first sealing ring and the second sealing ring are both provided with elastic hard baffles on the opposite sides thereof; The first sealing ring and the second sealing ring are both provided with a cavity for accommodating gas; At least one guide hole is provided in the positioning ring, which communicates with the cavities in the first sealing ring and the second sealing ring to provide a channel for gas interaction.
[0008] In the above technical solution, preferably, the second sealing ring is in a stretchable shape, and when air is introduced into the cavity of the second sealing ring, it undergoes stretching deformation to push the elastic hard baffle to move in a direction away from the pushing member.
[0009] In the above technical solution, preferably, the first sealing ring and the second sealing ring are made of soft silicone or silicone rubber, and the elastic hard baffle is made of hard rubber or polyurethane elastomer.
[0010] In the above technical solution, preferably, it also includes: A symmetrically arranged sealing plate is provided in the tail end of the tail sleeve, with the side thereof away from the flexible sealing body being in contact with the inner wall of the tail sleeve; The motion conversion mechanism has two ends connected to the flexible sealing body and the sealing plate respectively; As the flexible sealing body is deformed by force, the motion conversion mechanism drives the sealing plates on both sides to move toward the central axis of the optical fiber. The sealing plates on both sides are butted against the optical fiber and cover the connection between the optical fiber and the tail sleeve.
[0011] In the above technical solution, preferably, the motion conversion mechanism includes: An inclined seat is provided on the sealing plate; The long rod has two ends fixed on the flexible sealing body and slidably mounted on the inclined surface of the inclined surface seat; As the flexible sealing body deforms, one end of the long rod is driven to move along the inclined surface of the inclined surface seat, pushing the sealing plate to move in the direction toward the central axis of the optical fiber.
[0012] In the above technical solution, preferably, the sealing plate is provided with an adapting hole, and the adapting hole is provided with flexible fluororubber. When the sealing plates are connected to each other, the combined aperture of the adapting hole is adapted to fit closely with the outer diameter of the optical fiber.
[0013] In the above technical solution, preferably, a sealing ring is further provided on the inner ring of the positioning ring close to the optical fiber.
[0014] In the above technical solution, preferably, it also includes an energy storage elastic element, which is fixed between the side of the flexible sealing body away from the pushing member and the tail sleeve. As the flexible sealing body deforms, the energy storage elastic element expands and contracts to help the flexible sealing body fit closely to the outer wall of the optical fiber and the inner wall of the tail sleeve.
[0015] In the above technical solution, preferably, the energy storage elastic element is a spring, a ring piece is provided in the tail sleeve, and two ends of the spring are respectively fixed between the flexible sealing body and the ring piece.
[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention enables the flexible sealing body to deform under the action of the pusher, and the internal gas is compressed to expand it, so that it closely fits the outer wall of the optical fiber and the inner wall of the tail sleeve, effectively preventing the entry of impurities such as dust and water vapor.
[0017] The flexible sealing body is composed of an elastically deformable first sealing ring, a second sealing ring, and an elastic hard baffle. The flexible sealing body cooperates with the gas passages in the cavity and the guide hole. The elastic hard baffle transmits the force, and the first sealing ring compresses the cavity, causing the gas in the first sealing ring to flow into the cavity of the second sealing ring. Based on the elastic deformation characteristics of the sealing rings and the free interaction of gas between the cavities, the first and second sealing rings are tightly fitted to the tail sleeve and optical fiber in all directions, achieving a double sealing effect. Furthermore, through the motion conversion mechanism composed of the long rod and the bevel seat, the deformation force of the flexible sealing body is effectively utilized to drive the sealing plate and flexible fluororubber to re-seal the optical fiber. Cooperating with the sealing effect of the flexible sealing body itself, a multi-level sealing system is constructed from the connection between the optical fiber and the tail sleeve to the inner side, thereby improving the sealing reliability of the optical fiber connector.
[0018] While the flexible sealing body adheres to the outer wall of the optical fiber and the inner wall of the tail sleeve, the energy storage elastic element (spring) uses its own elastic energy storage to generate an auxiliary pressing force in the same direction as the expansion force of the flexible sealing body caused by gas compression, so that the flexible sealing body adheres to the outer wall of the optical fiber and the inner wall of the tail sleeve more tightly and stably.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the present invention provides a highly compatible optical fiber connector, comprising a tail sleeve 1 sleeved on the outside of the optical fiber, and further comprising: A flexible sealing body 2 with elastic deformation capability is provided between the outer wall of the optical fiber and the inner wall of the tail sleeve 1 and has a cavity 3 inside for accommodating gas; The positioning ring 4 is fixed to the inner wall of the tail sleeve 1 and fits the outer wall of the optical fiber. It is connected to the flexible sealing body 2 and is used to determine the position of the flexible sealing body 2 in the tail sleeve 1. The pusher 5 is coaxially arranged with the flexible sealing body 2 and has one end in vertical contact with the flexible sealing body 2 and the other end fixedly arranged inside the optical fiber connector; As the pusher 5 applies force to the flexible sealing body 2, the flexible sealing body 2 is deformed by the force, and the gas inside is compressed, causing the flexible sealing body 2 to expand and fit tightly against the outer wall of the optical fiber and the inner wall of the tail sleeve 1; A sealing ring 9 is further provided on the inner ring of the positioning ring 4 close to the optical fiber.
[0023] The tight fit of the flexible seal 2 (preferentially at the connection between the boot 1 and the optical fiber) forms a reliable sealing barrier, significantly improving the stability and reliability of the optical fiber connector in complex environments (such as humid and dusty areas). Compared with traditional simple sealing methods that rely solely on a single rubber gasket, this structure can adapt to various operating conditions during long-term use. The positioning ring 4 provides an accurate positioning reference for the flexible sealing body 2. When there are slight differences in the outer diameters of the optical fibers, it also ensures that the flexible sealing body 2 can function accurately. It can be adapted to a variety of optical fibers and has strong compatibility.
[0024] Moreover, the sealing operation is achieved by applying force to the flexible sealing body 2 with the help of the pusher 5. The insertion of the tail sleeve 1 is naturally combined with the activation of the sealing body, and no additional complicated operation is required to achieve sealing, which is simple and quick to operate.
[0025] like Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 As shown, the flexible sealing body 2 includes: A first sealing ring 21 and a second sealing ring 22 fixed on both sides of the positioning ring 4 and having elastic deformation capability; Elastic hard baffles 23 are provided on opposite sides of the first sealing ring 21 and the second sealing ring 22; The first sealing ring 21 and the second sealing ring 22 are both provided with a cavity 3 for accommodating gas; At least one guide hole 24 is provided in the positioning ring 4 , which communicates with the cavities 3 in the first sealing ring 21 and the second sealing ring 22 , providing a channel for gas exchange.
[0026] The first sealing ring 21 and the second sealing ring 22 are designed to work together to form a double sealing structure: On the one hand, it can more effectively prevent external impurities such as dust and water vapor from invading the optical fiber connection area from different directions, greatly enhancing the overall sealing performance; On the other hand, when encountering external impact or vibration, the two sealing rings can act as a buffer layer to absorb part of the energy, protect the optical fiber and internal precision components from damage, and ensure connection stability.
[0027] The second sealing ring 22 is in a stretchable shape. When air is introduced into the cavity 3 of the second sealing ring 22 , it is stretched and deformed to push the elastic hard baffle 23 to move in a direction away from the pushing member 5 .
[0028] The first sealing ring 21 and the second sealing ring 22 are made of soft silicone or silicone rubber, and the elastic hard baffle 23 is made of hard rubber or polyurethane elastomer.
[0029] Soft silicone and silicone rubber are used as the materials for the first sealing ring 21 and the second sealing ring 22. These materials have excellent elasticity, flexibility and aging resistance. They can not only ensure that they are not easily damaged during deformation such as compression and stretching, maintain long-term effective sealing function, but also adapt to the slight differences in the outer diameters of different optical fibers to achieve good fit. The elastic hard baffle 23 is made of materials such as hard rubber and polyurethane elastomer. Its hardness characteristics can provide strong support when the sealing ring expands to prevent excessive deformation. At the same time, when subjected to external force, it can effectively protect the relatively fragile internal sealing ring structure, so that the entire flexible sealing body 2 has both elasticity and rigidity, optimizing the overall performance.
[0030] like Figure 2 、 Figure 4 、 Figure 7 、 Figure 8 As shown, it also includes: The sealing plate 6 is symmetrically arranged and disposed in the tail end of the tail sleeve 1, with the side thereof away from the flexible sealing body 2 being in contact with the inner wall of the tail sleeve 1; The motion conversion mechanism 7 has two ends connected to the flexible sealing body 2 and the sealing plate 6 respectively; As the flexible sealing body 2 is deformed by force, the motion conversion mechanism 7 drives the sealing plates 6 on both sides to move toward the central axis of the optical fiber. The sealing plates 6 on both sides are connected to the optical fiber and cover the connection between the optical fiber and the tail sleeve 1.
[0031] The sealing plate 6 replaces the flexible sealing body 2 to form a hard seal on the connection between the tail sleeve 1 and the optical fiber, which complements the sealing effect of the flexible sealing body 2, blocking the intrusion paths of dust, water vapor, etc. from different angles, preventing impurities from penetrating from the gap between the sealing plate and the tail sleeve, and also providing a layer of protection for the flexible sealing body 2, thereby stabilizing the internal protection system.
[0032] like Figure 2 、 Figure 7 、 Figure 8 As shown, the motion conversion mechanism 7 includes: Inclined seat 71, provided on the sealing plate 6; The long rod 72 has two ends fixed to the flexible sealing body 2 and slidably mounted on the inclined surface of the inclined surface seat 71; As the flexible sealing body 2 deforms, one end of the long rod 72 is driven to move along the inclined surface of the inclined surface seat 71, pushing the sealing plate 6 to move in the direction toward the central axis of the optical fiber.
[0033] The transmission link between the inclined seat 71 and the long rod 72 is simple and efficient, with a quick transmission response and no redundant components, thus saving space to the greatest extent.
[0034] The sealing plate 6 is provided with an adapting hole 8, in which a flexible fluororubber is provided. When the sealing plates 6 are connected to each other, the combined aperture of the adapting hole 8 is adapted and fits tightly with the outer diameter of the optical fiber.
[0035] When the sealing plates 6 are docked with each other, the combined aperture of the adapter hole 8 is closely adapted to the outer diameter of the optical fiber, ensuring that the sealing plate 6 tightly wraps the optical fiber, preventing the optical fiber from shaking or displacing, and improving the connection stability; on the other hand, the flexible fluororubber has good flexibility, corrosion resistance and insulation, which can not only buffer the pressure on the optical fiber when the sealing plate 6 is docked, avoid scratching the optical fiber, but also resist erosion by external chemicals during long-term use, thereby extending the service life of the optical fiber.
[0036] like Figure 2 、 Figure 4 、 Figure 6 As shown, it also includes an energy storage elastic element 10, which is fixed between the side of the flexible sealing body 2 away from the pushing member 5 and the tail sleeve 1. As the flexible sealing body 2 deforms, the energy storage elastic element 10 expands and contracts to help the flexible sealing body 2 fit closely to the outer wall of the optical fiber and the inner wall of the tail sleeve 1.
[0037] The energy storage elastic element 10 is a spring. A ring piece 11 is provided in the tail sleeve 1 . Both ends of the spring are fixed between the flexible sealing body 2 and the ring piece 11 .
[0038] The energy-storage elastic element 10 (e.g., a spring) expands and contracts with the deformation of the flexible seal 2, continuously applying auxiliary thrust throughout use. If the initial sealing pressure of the flexible seal 2 decreases due to temperature changes, aging over time, or slight external impact, the spring's elastic recovery force can be promptly replenished, ensuring that the flexible seal 2 always closely adheres to the outer wall of the optical fiber and the inner wall of the tail sleeve 1. This dynamic compensation mechanism greatly enhances the reliability and durability of the seal, allowing the optical fiber connector to maintain a good seal in complex and changing environmental conditions, such as outdoor wind and rain erosion and large temperature fluctuations, or indoor conditions with frequent plugging and unplugging and vibration. This effectively resists the intrusion of dust and moisture, ensuring stable transmission of optical signals.
[0039] The working principle and use process of the present invention: When assembling the optical fiber connector, the tail sleeve 1 is used as a docking component and is pre-mounted on the optical fiber. After the other components are assembled, the tail sleeve 1 is moved toward the end of the optical fiber connector for docking. At this time, the pusher 5 located in the optical fiber connector contacts the elastic hard baffle 23 and applies a transmission force. The elastic hard baffle 23 quickly transmits the force to the first sealing ring 21 closely connected thereto. The cavity 3 containing gas inside the first sealing ring 21 is compressed, and the gas pressure rises sharply. The compressed high-pressure gas in the first sealing ring 21 quickly flows through the guide hole 24 to the cavity 3 of the second sealing ring 22. The second sealing ring 22 into which the high-pressure gas flows is then elastically deformed, causing the second sealing ring 22 to fit tightly against the tail sleeve 1 and the optical fiber. At the same time, the first sealing ring 21 fits tightly against the optical fiber and the tail sleeve 1 under the cooperation of its own elastic restoring force, the gas reaction force, and the structural design. During this process, since the second sealing ring 22 is in a stretchable shape, the gas pressure causes it to stretch and deform, pushing the elastic hard baffle 23 on its outer side to move in a direction away from the pusher 5, acting on the energy storage elastic element 10 (spring) to expand and contract and store energy to generate additional boosting force, coordinating with the second sealing ring 22 to fit the outer wall of the optical fiber and the inner wall of the tail sleeve 1; The long rod 72 fixedly connected to the elastic hard baffle 23 on one side of the second sealing ring 22 is also pushed, and one end of the long rod 72 moves along the inclined surface of the inclined surface seat 71. The inclined surface design converts the lateral driving force of the long rod 72 into a longitudinal driving force, prompting the sealing plates 6 on both sides to gradually move closer to the optical fiber under the action of the driving force, and finally achieve docking. The sealing plate 6 covers the connection between the optical fiber and the tail sleeve 1, and the flexible fluororubber in the sealing plate 6 automatically adapts to the outer diameter of the optical fiber and fits tightly to the optical fiber, thus completing the assembly and sealing operation.
