Description

Technical Field

[0001] The invention relates to the technical field of optical fibers, in particular to a self-testable optical fiber connector. Background Art

[0002] Optical fiber has been widely used in many fields such as communications, medical treatment, industrial manufacturing, and military due to its significant advantages such as high bandwidth, low loss, and strong anti-interference ability. As a key component for achieving reliable connection between optical fibers, the performance of optical fiber connectors is directly related to the stability and transmission efficiency of the entire optical fiber system. With the continuous expansion of optical fiber application scenarios and the increasing technical requirements, the functions of optical fiber connectors have also been more stringently challenged. In high-speed optical communication networks, even minor connection failures may cause a large number of data transmission errors or even interruptions, seriously affecting the quality of communication; in optical fiber laser processing equipment, unstable optical fiber connections will cause abnormal laser energy transmission, reduce processing accuracy and efficiency, and even damage equipment. Therefore, ensuring the reliability of optical fiber connections has become a key issue that needs to be urgently addressed in the field of optical fiber applications.

[0003] It is difficult for existing fiber optic connectors to effectively detect the performance of optical fibers and related equipment before connection, which may cause various problems in actual use. Although some traditional fiber optic connectors have tried to add self-test functions, they still have many defects. For example, in the existing public patent (publication number: CN107065084B), the fiber optic connector relies on a large number of electromagnets to provide power to control the movement of the optical fiber and the operation of the detection structure. However, this design not only greatly increases the cost of the product, but also the electromagnets will generate strong electromagnetic interference during operation. These electromagnetic interferences will seriously affect the transmission quality of the optical signal in the optical fiber, causing the optical signal to be distorted or attenuated. At the same time, they will also interfere with the normal operation of the detection element, reduce the detection accuracy, and cause deviations in the detection results, which cannot truly reflect the performance of the optical fiber and the equipment.

[0004] In addition, key electronic components such as the micro power sensors integrated inside existing connectors often cannot be reused after completing a fiber optic connection and can only remain inside the connector. This means that each time a fiber optic connection is made, a new set of detection components is required, which greatly increases the cost of the fiber optic connection. For large-scale fiber optic connection application scenarios, such as massive fiber optic wiring in data centers and frequent equipment upgrades in communication base stations, the high connection cost has become an important factor restricting its development. Therefore, it is urgent to develop a self-inspecting fiber optic connector with a simple structure, low cost, and reusable detection components that can effectively avoid electromagnetic interference. Summary of the invention

[0005] Technical issues solved

[0006] Aiming at the deficiencies of the prior art, the present invention provides a fiber optic connector capable of self-checking, which solves the problems of large electromagnetic interference, high cost, and non-reusable detection components in existing fiber optic connectors.

[0007] Technical solution

[0008] To achieve the above object, the present invention is realized through the following technical solutions: A fiber optic connector capable of self-checking includes a connection mechanism. Inside the connection mechanism, a moving mechanism is slidably arranged near one side, a self-checking mechanism is slidably clamped near the middle position, and a fiber optic coupler is penetrated through the side far from the moving mechanism inside the connection mechanism.

[0009] The self-checking mechanism includes an insertion frame. An access slot is opened on one side of the insertion frame. A steering shaft is rotatably arranged at the middle position inside the insertion frame. A micro power probe is embedded on the side of the steering shaft near the moving mechanism, and a steering rack is fixedly arranged at the upper end of the outer side of the steering shaft.

[0010] The moving mechanism includes a moving slide plate. A moving cylinder is penetrated through the middle position inside the moving slide plate. An inner fixed cylinder is fixedly arranged inside the moving cylinder. A stable slider is fixedly arranged on one side of the moving slide plate. An inner slider is fixedly arranged on the other side of the moving slide plate. The other end of the inner slider is fixedly provided with a dust-proof slide plate. A sliding button is fixedly arranged on one side of the dust-proof slide plate. A power rack is fixedly arranged on one side of the moving slide plate.

[0011] Preferably, the connection mechanism includes a protection frame. An outlet is opened on the side of the protection frame near the fiber optic coupler. An inlet is penetrated through one side of the protection frame. Spring telescopic rods are fixedly arranged at the positions near the inlet on the front and rear ends inside the protection frame. Support frames are fixedly arranged on the opposite sides of the two spring telescopic rods. Support shafts are rotatably arranged inside the two support frames.

[0012] Preferably, a stable chute is opened on one side inside the protection frame. An outer chute is opened on the side far from the stable chute inside the protection frame. An inner chute is opened inside the outer chute. The stable slider is slidably arranged inside the stable chute. The inner slider is slidably arranged inside the outer chute and the inner chute. The dust-proof slide plate is slidably arranged inside the outer chute.

[0013] Preferably, an inner support block is fixedly arranged on the side far from the inlet inside the protection frame. A driven rack is slidably arranged on one side of the inner support block. A gear is rotatably arranged on the side of the inner support block near the driven rack. The power rack is slidably arranged inside the inner support block. The power rack and the driven rack are respectively meshed and connected on both sides of the gear. The other side rack of the driven rack is meshed and connected with the steering rack.

[0014] Preferably, an installation opening is provided at a position close to the middle on one side of the protection frame, and the self-check mechanism is slidably clamped inside the connection mechanism through the installation opening, and a mounting and dismounting groove is provided at the upper end of the insertion frame.

[0015] Preferably, an acrylic plate is fixedly provided at the opening at the upper end of the connection mechanism.

[0016] Preferably, a fixed optical fiber is fixedly provided at one end of the fiber optic coupler, and a protective sleeve is fixedly provided outside the fixed optical fiber.

[0017] Working principle: In the self-check stage, first, the optical fiber to be connected is carefully inserted into the inner fixed cylinder of the moving mechanism to ensure that the optical fiber is firmly installed. Subsequently, a specific detection signal is input into the optical fiber to be connected in the inner fixed cylinder. At this time, the micro power probe in the self-check mechanism starts to function. It can accurately detect key parameters such as the signal intensity and stability of the optical fiber transmission. The micro power probe converts the received optical signal into an electrical signal, analyzes and processes it, and judges whether the performance of the optical fiber and the equipment connected thereto is normal. For example, if the detected signal intensity is lower than the standard value, or there are obvious fluctuations in the signal, it indicates that the optical fiber may be damaged or the connection is poor, etc., and troubleshooting and repair are required.

[0018] If the self-check result shows that the performance of the optical fiber and related equipment is normal, it enters the connection stage. The operator manually controls the sliding button, and the movement of the sliding button will drive the connected moving slide plate to slide smoothly along the preset track inside the protection frame. Since the moving slide plate is fixed to the optical fiber to be connected, the optical fiber to be connected will also move synchronously with the moving slide plate towards the fiber optic coupler. During the movement, the power rack on the moving slide plate will interact with the gear. The movement of the power rack pushes the gear to rotate, and the rotation of the gear drives the driven rack engaged with it to move. The driven rack is closely engaged with the steering rack, and the movement of the driven rack drives the steering rack to rotate. The rotation of the steering rack causes the fixed steering shaft to rotate. When the steering shaft rotates, the hollow position inside it gradually faces towards the space between the optical fiber to be connected and the fiber optic coupler. During the rotation of the steering shaft, the micro power probe continuously detects the optical fiber to be detected and monitors the change of the optical fiber transmission signal in real time.

[0019] When the optical fiber to be detected is successfully inserted into the fiber optic coupler, the optical fiber connection is completed. At this time, the fixed structure inside the connection mechanism will ensure that the optical fiber connection is firm and reliable. After the connection is completed, the operator can pull out the self-check mechanism from the connection mechanism through the mounting and dismounting groove for the next use. In order to maintain the protection performance of the connection mechanism and prevent foreign impurities such as dust and moisture from entering the outside and affecting the optical fiber connection quality, a stopper can be inserted into the installation opening to effectively protect the connection mechanism.

[0020] Beneficial effects

[0021] The present invention provides a fiber optic connector capable of self-checking, with the following beneficial effects:

[0022] 1. The present invention provides a fiber optic connector capable of self-checking. Through a unique structural design, the self-checking mechanism of this fiber optic connector can be conveniently disassembled and reused. After completing the fiber optic connection operation, the self-checking mechanism can be easily taken out of the connection mechanism through the installation and removal slot. After simple cleaning and calibration, it can be put into use again. This innovative design has completely changed the status quo of disposable use of expensive electronic components such as micro power probes in traditional connectors, greatly reducing the cost of fiber optic connection. Taking a data center as an example, when carrying out large-scale fiber optic cabling, using this connector can significantly reduce the procurement cost of detection components. In the long run, it can save a large amount of funds for enterprises, improve the economic benefits of products, and make them more competitive in the market.

[0023] 2. The present invention provides a fiber optic connector capable of self-checking. Different from traditional fiber optic connectors that rely on electromagnets for driving, this connector uses a manual control sliding button to drive a moving mechanism to achieve fiber optic connection. This mechanical driving method fundamentally avoids electromagnetic interference generated by electromagnets. During the detection process, the micro power probe will not be affected by external electromagnetic noise, and can stably and accurately detect the signals transmitted by the fiber optic, thereby improving the detection accuracy. Accurate detection results help to timely discover potential problems before fiber optic connection, ensuring the reliability of the connection. At the same time, reducing electromagnetic interference is also beneficial to improving the stability of the entire fiber optic connection system, reducing the incidence of signal transmission failures caused by electromagnetic interference, and ensuring the normal operation of the fiber optic system in various complex environments.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1-9 shown, the embodiment of the present invention provides a fiber optic connector capable of self-checking, including a connection mechanism 1. A moving mechanism 7 is slidably arranged at a position close to one side inside the connection mechanism 1. A self-checking mechanism 2 is slidably clamped at a position close to the middle inside the connection mechanism 1. A fiber optic coupler 6 is penetrated and arranged at a side far from the moving mechanism 7 inside the connection mechanism 1. One end of the fiber optic coupler 6 is fixedly provided with a fixed optical fiber 5. A protective sleeve 4 is fixedly arranged outside the fixed optical fiber 5. An acrylic board 3 is fixedly arranged at the opening at the upper end of the connection mechanism 1;

[0036] Specifically, in the above specific embodiment, the connecting mechanism 1 serves as the basic framework of the entire optical fiber connector, providing installation positions and support for the moving mechanism 7, the self-checking mechanism 2, and the optical fiber coupling connector 6. Among them, the acrylic plate 3 is fixed at the upper opening of the connecting mechanism 1, playing a role in protection and facilitating the observation of the internal situation. The optical fiber coupling connector 6 penetrates through one side of the connecting mechanism 1, and one end is connected to the fixed optical fiber 5. The protective sleeve 4 outside the fixed optical fiber 5 is used to protect the optical fiber from external damage, ensuring the stable transmission of optical signals. This overall layout design enables the orderly combination of various components, ensuring the compactness and stability of the connector structure. The setting of the acrylic plate 3 can not only prevent dust and other impurities from entering the connector internal to affect the connection performance, but also facilitate the operator to observe the internal connection state at any time and discover problems in a timely manner. The protection of the fixed optical fiber 5 by the protective sleeve 4 can effectively extend the service life of the optical fiber and improve the reliability of optical fiber connection.

[0037] As Figure 6 and 7 shown, the self-checking mechanism 2 includes an insertion frame 201. An access slot 206 is provided on one side of the insertion frame 201. A steering shaft 203 is rotatably arranged at the middle position inside the insertion frame 201. A micro power probe 205 is embedded inside the steering shaft 203 near the moving mechanism 7. A steering rack 204 is fixedly arranged at the upper end position outside the steering shaft 203.

[0038] Specifically, in the above specific embodiment, the insertion frame 201 is the carrier of the self-checking mechanism 2, and the access slot 206 is used for the optical signal transmission of the optical fiber to be detected during the detection process. The rotation of the steering shaft 203 is the key to realizing the detection function. When the related transmission components drive the steering rack 204 to rotate, the steering shaft 203 rotates accordingly. The micro power probe 205 is embedded in the steering shaft 203 and can detect the optical signal passing through the access slot 206 from different angles during the rotation of the steering shaft 203, converting the optical signal into an electrical signal, thereby judging the transmission performance of the optical fiber. Finally, the design of the access slot 206 enables the optical signal to smoothly enter the self-checking mechanism 2 for detection, ensuring the accuracy of the detection. The cooperation between the steering shaft 203 and the steering rack 204 enables the micro power probe 205 to detect the optical signal at different positions, improving the comprehensiveness of the detection. The rotatable design can more flexibly adapt to the detection requirements of different optical fibers, and the embedding method of the micro power probe 205 protects the detection element and improves its service life.

[0039] As Figure 8 and 9As shown, the moving mechanism 7 includes a moving slide plate 704. A moving cylinder 702 is disposed through the middle position inside the moving slide plate 704. An inner fixed cylinder 703 is fixedly disposed inside the moving cylinder 702. A stable slider 705 is fixedly disposed on one side of the moving slide plate 704. An inner slider 708 is fixedly disposed on the other side of the moving slide plate 704. A dust-proof slide plate 706 is fixedly disposed at the other end of the inner slider 708. A sliding button 707 is fixedly disposed on one side of the dust-proof slide plate 706. A power rack 701 is fixedly disposed on one side of the moving slide plate 704;

[0040] Specifically, in the above specific embodiment, the moving slide plate 704 is the core component of the moving mechanism 7. By sliding the stable slider 705 and the inner slider 708 in the corresponding chutes of the connecting mechanism 1 respectively, the smoothness of the movement is ensured. The moving cylinder 702 and the inner fixed cylinder 703 are used to fix the optical fiber to be connected, so that it maintains a stable position during the movement. The operator pushes the sliding button 707 to drive the movement of the moving slide plate 704, and the power rack 701 on the moving slide plate 704 moves accordingly. During the movement of the power rack 701, it will interact with transmission components such as the gear 105 in the connecting mechanism 1 to realize the drive of other components. The dust-proof slide plate 706 can prevent dust and other impurities from entering the inside of the connecting mechanism 1 and protect the normal operation of the internal components. Thus, the stable sliding structure and the fixing device ensure the accuracy and reliability of the optical fiber to be connected during the movement, and reduce the influence of the optical fiber shaking or deviation on the connection. The setting of the power rack 701 provides an interface for the moving mechanism 7 to be linked with other components, facilitating the realization of automatic optical fiber connection operations. The design of the dust-proof slide plate 706 protects the internal components, extends the service life of the connector, and improves its applicability in different environments.

[0041] As Figures 3-5 As shown, the connecting mechanism 1 includes a protective frame 101. An outlet 107 is opened on one side of the protective frame 101 close to the optical fiber coupler 6. An inlet 112 is disposed through one side of the protective frame 101. Spring telescopic rods 110 are fixedly disposed at positions on both the front and rear ends of the protective frame 101 close to the inlet 112. Support frames 102 are fixedly disposed on the opposite sides of the two spring telescopic rods 110. Support shafts 111 are rotatably disposed inside the two support frames 102;

[0042] Specifically, in the above specific embodiments, the protective frame 101 provides a protective housing for the entire connection mechanism 1. The inlet 112 is the channel through which the optical fiber to be connected enters the connection mechanism 1, and the outlet 107 is the channel for the output of the optical signal after the connection is completed. The combination of the spring telescopic rod 110 and the support frame 102 plays a role of buffering and guiding. When the optical fiber to be connected is inserted, the spring telescopic rod 110 can be telescoped according to the insertion force of the optical fiber, providing a certain buffering force to prevent the optical fiber from being damaged due to excessive insertion. The support shaft 111 in the support frame 102 can assist in guiding the optical fiber to smoothly enter the inner fixing cylinder 703, ensuring the accuracy of the optical fiber insertion. Finally, the reasonable layout of the inlet 112 and the outlet 107 ensures the smooth transmission of the optical signal. The design of the spring telescopic rod 110 and the support frame 102 effectively protects the safety of the optical fiber during the insertion process, reduces the risk of optical fiber damage, and improves the success rate of optical fiber connection. At the same time, this design also makes the optical fiber insertion operation more convenient and easy, improving the user experience.

[0043] As Figures 1-6 shown, an installation opening 108 is provided at a position near the middle on one side of the protective frame 101. The self-check mechanism 2 is slidably clamped inside the connection mechanism 1 through the installation opening 108, and a disassembly slot 202 is provided at the upper end of the insertion frame 201;

[0044] Specifically, in the above specific embodiments, the installation opening 108 provides a position for the installation and positioning of the self-check mechanism 2. The self-check mechanism 2 is installed inside the connection mechanism 1 by means of sliding clamping, ensuring the stability and detachability of its installation. The opening of the disassembly slot 202 facilitates the operator to use tools or directly remove the self-check mechanism 2 from the connection mechanism 1 by hand. After a fiber optic connection detection is completed, the self-check mechanism 2 can be disassembled for cleaning, maintenance, or reused on other connectors. Thus, the design of the installation opening 108 and the disassembly slot 202 greatly improves the flexibility and maintainability of the use of the self-check mechanism 2. The reusable self-check mechanism 2 reduces the cost of fiber optic connection and improves the cost performance of the product. At the same time, the convenient installation and disassembly method also facilitates the separate upgrade and improvement of the self-check mechanism 2, enhancing the performance of the entire connector.

[0045] As Figures 3-5 shown, a stable sliding groove 109 is provided on one side inside the protective frame 101, an outer sliding groove 113 is provided on the side inside the protective frame 101 away from the stable sliding groove 109, an inner sliding groove 103 is provided inside the outer sliding groove 113, a stable slider 705 is slidably arranged inside the stable sliding groove 109, an inner slider 708 is slidably arranged inside the outer sliding groove 113 and the inner sliding groove 103, and a dust-proof sliding plate 706 is slidably arranged inside the outer sliding groove 113;

[0046] Specifically, in the above specific embodiments, the stable chute 109, the outer chute 113, and the inner chute 103 provide precise sliding tracks for the stable slider 705, the inner slider 708, and the dust-proof slide plate 706 of the moving mechanism 7. The stable slider 705 slides within the stable chute 109, ensuring the lateral stability of the moving slide plate 704 during movement; the inner slider 708 slides within the multi-layer chute, further enhancing the stability of the moving slide plate 704 and restricting its moving direction; the dust-proof slide plate 706 slides within the outer chute 113, which can not only prevent dust from entering the inside of the connecting mechanism 1 but also move along with the moving slide plate 704, playing a protective role. The cooperation between these chutes and sliders enables the moving mechanism 7 to move smoothly and accurately. Ultimately, the precisely designed chute and slider structure ensure the accuracy and stability of the movement of the moving mechanism 7, improving the accuracy of optical fiber connection. The design of the multi-layer chute increases the stability and reliability of the moving mechanism 7, reducing the shaking and deviation during movement. The setting of the dust-proof slide plate 706 protects the cleanliness inside the connecting mechanism 1, reduces the risk of connection failures caused by dust and other impurities, and extends the service life of the connector.

[0047] As Figures 1-5 shown, on one side of the protective frame 101 away from the inlet 112, an inner support block 106 is fixedly arranged. On one side of the inner support block 106, a driven rack 104 is slidably arranged. On the side of the inner support block 106 close to the driven rack 104, a gear 105 is rotatably arranged. The power rack 701 is slidably arranged inside the inner support block 106. The power rack 701 and the driven rack 104 are respectively meshed and connected on both sides of the gear 105. The other side rack of the driven rack 104 is meshed and connected with the steering rack 204;

[0048] Specifically, in the above specific embodiments, when the power rack 701 of the moving mechanism 7 moves along with the moving slide plate 704, the power rack 701 will mesh with the gear 105. Since the power rack 701 and the driven rack 104 are respectively located on both sides of the gear 105 and both mesh with the gear 105, the movement of the power rack 701 will drive the gear 105 to rotate, and then the driven rack 104 will move. The movement of the driven rack 104 will mesh with the steering rack 204, thereby driving the steering rack 204 to rotate, and finally realizing the rotation of the steering shaft 203, completing the linkage between the detection action of the self-checking mechanism 2 and the moving mechanism 7. This gear 105 - rack transmission structure realizes the reliable linkage between the moving mechanism 7 and the self-checking mechanism 2, ensuring the synchronism and accuracy of the optical fiber connection and the detection action. Compared with complex electronic control systems, the pure mechanical transmission structure is more stable and reliable, reducing the probability of failures, lowering the maintenance cost, and improving the overall performance and service life of the optical fiber connector.
