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] In view of the deficiencies of the prior art, the present invention provides a self-testing optical fiber connector, which solves the problems of the prior optical fiber connector having large electromagnetic interference, high cost and non-reusable detection elements.

[0009] The self-test mechanism comprises an insertion frame, one side of the insertion frame is provided with an entry and exit slot, a steering shaft is rotatably arranged at the middle position inside the insertion frame, a micro power probe is embedded in the steering shaft near the side of the moving mechanism, and a steering rack is fixedly arranged at the upper end position outside the steering shaft;

[0010] The moving mechanism includes a moving slide, a moving cylinder is arranged through the middle position inside the moving slide, an inner fixed cylinder is fixedly arranged inside the moving cylinder, a stabilizing slider is fixedly arranged on one side of the moving slide, an inner slider is fixedly arranged on the other side of the moving slide, a dustproof slide is fixedly arranged on the other end of the inner slider, a sliding button is fixedly arranged on one side of the dustproof slide, and a power rack is fixedly arranged on one side of the moving slide.

[0011] Preferably, the connecting mechanism includes a protective frame, a wire outlet is provided inside the protective frame near the optical fiber coupling connector, a wire inlet is provided through one side of the protective frame, spring telescopic rods are fixedly provided at the front and rear ends of the protective frame near the wire inlet, support frames are fixedly provided on opposite sides of the two spring telescopic rods, and support shafts are rotatably provided inside the two support frames.

[0012] Preferably, a stabilizing groove is provided on one side of the interior of the protective frame, an outer groove is provided on the side of the interior of the protective frame away from the stabilizing groove, an inner groove is provided inside the outer groove, the stabilizing slider is slidably arranged inside the stabilizing groove, the inner slider is slidably arranged inside the outer groove and the inner groove, and the dustproof slider is slidably arranged inside the outer groove.

[0013] Preferably, an inner support block is fixedly provided on the side of the protective frame away from the wire inlet, a driven rack is slidably provided on one side of the inner support block, a gear is rotatably provided on the side of the inner support block close to the driven rack, the power rack is slidably provided inside the inner support block, the power rack and the driven rack are respectively meshed and connected at both sides of the gear, and the rack on the other side of the driven rack is meshed and connected with the steering rack.

[0014] Preferably, a mounting opening is provided on one side of the protection frame near the middle position, the self-inspection mechanism is slidably engaged and arranged inside the connecting mechanism through the mounting opening, and a mounting and disassembly groove is provided on the upper end of the insertion frame.

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

[0016] Preferably, a fixed optical fiber is fixedly provided at one end of the optical fiber coupling connector, and a protective cover is fixedly provided on the outside of the fixed optical fiber.

[0017] Working principle: During the self-test stage, first carefully insert the optical fiber to be connected into the inner fixing tube of the mobile 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 fixing tube. At this time, the miniature power sensor in the self-test mechanism begins to play a role. It can accurately detect key parameters such as the signal strength and stability of the optical fiber transmission. The miniature power sensor converts the received optical signal into an electrical signal, and analyzes and processes it to determine whether the performance of the optical fiber and the equipment connected to it is normal. For example, if the signal strength is detected to be lower than the standard value, or there is a significant fluctuation in the signal, it indicates that the optical fiber may be damaged or poorly connected, and needs to be checked and repaired.

[0018] If the self-test results show that the performance of the optical fiber and related equipment is normal, the connection stage will begin. 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 protective frame. Since the moving slide plate is fixed together with the optical fiber to be connected, the optical fiber to be connected will also move synchronously with the moving slide plate toward the direction of the optical fiber coupling connector. During the movement, the power rack on the moving slide plate will interact with the gear. The movement of the power rack drives the gear to rotate, and the rotation of the gear drives the driven rack meshed with it to move. The driven rack is tightly meshed 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 steering shaft fixed to it to rotate. When the steering shaft rotates, its internal hollow position gradually faces between the optical fiber to be connected and the optical fiber coupling connector. During the rotation of the steering shaft, the micro power sensor continuously detects the optical fiber to be detected and monitors the changes in the optical fiber transmission signal in real time.

[0019] When the optical fiber to be tested is successfully inserted into the optical fiber coupling connector, 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-test mechanism from the connection mechanism through the installation and removal slot for next use. In order to maintain the protective performance of the connection mechanism and prevent external impurities such as dust and moisture from entering and affecting the quality of the optical fiber connection, a block can be inserted inside the installation port to effectively protect the connection mechanism.

[0020] Beneficial Effects

[0021] The present invention provides a self-testable optical fiber connector, which has the following beneficial effects:

[0022] 1. The present invention provides a self-inspection optical fiber connector. The self-inspection optical fiber connector realizes the convenient disassembly and reuse of the self-inspection mechanism through a unique structural design. After completing the optical fiber connection operation, the self-inspection mechanism can be easily removed from the connection mechanism through the installation and removal slot. After simple cleaning and calibration, it can be put into use again. This innovative design completely changes the current situation of one-time use of expensive electronic components such as miniature power sensors in traditional connectors, and greatly reduces the cost of optical fiber connection. Taking the data center as an example, when conducting large-scale optical fiber wiring, the use of this connector can significantly reduce the procurement cost of detection components. In the long run, it can save a lot of money for the company, improve the economic benefits of the product, and make it more advantageous in market competition.

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

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0035] like Figure 1-9 As shown, an embodiment of the present invention provides a self-inspection optical fiber connector, including a connection mechanism 1, a moving mechanism 7 is slidably provided near one side of the connection mechanism 1, a self-inspection mechanism 2 is slidably and snap-fitted near the middle position of the connection mechanism 1, an optical fiber coupling connector 6 is penetrated and provided on the side of the connection mechanism 1 away from the moving mechanism 7, a fixed optical fiber 5 is fixedly provided at one end of the optical fiber coupling connector 6, a protective cover 4 is fixedly provided on the outside of the fixed optical fiber 5, and an acrylic plate 3 is fixedly provided at the opening of 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 supports for the moving mechanism 7, the self-test 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, which plays a role of protection and facilitates observation of the internal situation. The optical fiber coupling connector 6 runs through one side of the connecting mechanism 1, and one end is connected to the fixed optical fiber 5. The protective cover 4 outside the fixed optical fiber 5 is used to protect the optical fiber from external damage and ensure the stable transmission of the optical signal. This overall layout design allows the various components to be combined in an orderly manner, 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 to affect the connection performance, but also facilitate the operator to observe the internal connection status at any time and find problems in time. The protection of the fixed optical fiber 5 by the protective cover 4 can effectively extend the service life of the optical fiber and improve the reliability of the optical fiber connection.

[0037] like Figure 6 and 7 As shown, the self-test mechanism 2 includes an insertion frame 201, a one side of the insertion frame 201 is provided with an entry and exit slot 206, a steering shaft 203 is rotatably provided at the middle position inside the insertion frame 201, a micro power probe 205 is embedded in the steering shaft 203 near the side of the moving mechanism 7, and a steering rack 204 is fixedly provided at the upper end position of the steering shaft 203;

[0038] Specifically, in the above specific embodiment, the insertion frame 201 is the carrier of the self-test mechanism 2, and the inlet and outlet slot 206 is used for the optical signal transmission of the optical fiber to be tested during the detection process. The rotation of the steering shaft 203 is the key to realizing the detection function. When the transmission component related to it drives 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 inlet and outlet slot 206 from different angles during the rotation of the steering shaft 203, and convert the optical signal into an electrical signal, so as to judge the transmission performance of the optical fiber. Finally, the design of the inlet and outlet slot 206 enables the optical signal to smoothly enter the self-test mechanism 2 for detection, thereby ensuring the accuracy of the detection. The coordination of the steering shaft 203 and the steering rack 204 enables the micro power probe 205 to detect the optical signal at different positions, thereby 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 increases its service life.

[0039] like Figure 8 and 9As shown, the moving mechanism 7 includes a moving slide 704, a moving cylinder 702 is provided in the middle position inside the moving slide 704, an inner fixed cylinder 703 is fixedly provided inside the moving cylinder 702, a stabilizing slider 705 is fixedly provided on one side of the moving slide 704, an inner slider 708 is fixedly provided on the other side of the moving slide 704, a dustproof slide 706 is fixedly provided on the other end of the inner slider 708, a sliding button 707 is fixedly provided on one side of the dustproof slide 706, and a power rack 701 is fixedly provided on one side of the moving slide 704;

[0040] Specifically, in the above specific embodiment, the moving slide 704 is the core component of the moving mechanism 7. The stable slider 705 and the inner slider 708 slide in the corresponding slide groove of the connecting mechanism 1 respectively, ensuring the stability of the movement. 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 moving slide 704 to move, and the power rack 701 on the moving slide 704 moves accordingly. During the movement, the power rack 701 will interact with the transmission components such as the gear 105 in the connecting mechanism 1 to drive other components. The dustproof slide 706 can prevent dust and other impurities from entering the interior of the connecting mechanism 1 and protect the normal operation of the internal components. Therefore, the stable sliding structure and fixing device ensure the accuracy and reliability of the optical fiber to be connected during the movement process, and reduce the influence of the shaking or offset of the optical fiber on the connection. The setting of the power rack 701 provides an interface for the moving mechanism 7 to be linked with other components, which is convenient for realizing the automated optical fiber connection operation. The design of the dustproof sliding plate 706 protects the internal components, prolongs the service life of the connector and improves its applicability in different environments.

[0041] like Figure 3-5 As shown, the connection mechanism 1 includes a protection frame 101, a wire outlet 107 is provided on one side of the protection frame 101 near the optical fiber coupling connector 6, a wire inlet 112 is provided on one side of the protection frame 101, spring telescopic rods 110 are fixedly provided at the front and rear ends of the protection frame 101 near the wire inlet 112, support frames 102 are fixedly provided on the opposite sides of the two spring telescopic rods 110, and support shafts 111 are rotatably provided inside the two support frames 102;

[0042] Specifically, in the above specific embodiment, the protective frame 101 provides a protective shell for the entire connection mechanism 1, the line inlet 112 is the channel for the optical fiber to be connected to enter the connection mechanism 1, and the line outlet 107 is the channel for the optical signal to be output 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 extended and retracted according to the force of the optical fiber insertion, providing a certain buffer force to avoid damage to the optical fiber due to excessive insertion. The support shaft 111 in the support frame 102 can assist in guiding the optical fiber to smoothly enter the internal fixed cylinder 703, ensuring the accuracy of the optical fiber insertion. Finally, the reasonable layout of the line inlet 112 and the line 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 damage to the optical fiber, 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, and improves the user experience.

[0043] like Figure 1-6 As shown, a mounting opening 108 is provided near the middle of one side of the protection frame 101, and the self-test mechanism 2 is slidably connected and arranged inside the connecting mechanism 1 through the mounting opening 108, and a mounting and disassembly groove 202 is provided at the upper end of the insertion frame 201;

[0044] Specifically, in the above-mentioned specific embodiment, the installation port 108 provides a location for the self-test mechanism 2 to be installed and positioned. The self-test mechanism 2 is installed in the connecting mechanism 1 by sliding and snapping, which ensures the stability and detachability of its installation. The opening of the installation and disassembly groove 202 makes it convenient for the operator to use tools or directly remove the self-test mechanism 2 from the connecting mechanism 1. After completing a fiber optic connection test, the self-test mechanism 2 can be disassembled for cleaning, maintenance or reused on other connectors. Therefore, the design of the installation port 108 and the installation and disassembly groove 202 greatly improves the flexibility and maintainability of the self-test mechanism 2. The reusable self-test 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 independent upgrade and improvement of the self-test mechanism 2, thereby improving the performance of the entire connector.

[0045] like Figure 3-5 As shown, a stabilizing groove 109 is provided on one side of the protection frame 101, an outer groove 113 is provided on one side of the protection frame 101 away from the stabilizing groove 109, an inner groove 103 is provided inside the outer groove 113, a stabilizing slider 705 is slidably disposed inside the stabilizing groove 109, an inner slider 708 is slidably disposed inside the outer groove 113 and the inner groove 103, and a dustproof slider 706 is slidably disposed inside the outer groove 113;

[0046] Specifically, in the above specific embodiment, the stable slide groove 109, the outer slide groove 113 and the inner slide groove 103 provide precise sliding tracks for the stable slider 705, the inner slider 708 and the dustproof slider 706 of the mobile mechanism 7. The stable slider 705 slides in the stable slide groove 109 to ensure the lateral stability of the mobile slider 704 during the movement; the inner slider 708 slides in the multi-layer slide groove to further enhance the stability of the mobile slider 704 and limit its moving direction; the dustproof slider 706 slides in the outer slide groove 113 to prevent dust from entering the interior of the connecting mechanism 1 and to move with the mobile slider 704 to play a protective role. The cooperation of these slide grooves and sliders enables the mobile mechanism 7 to move smoothly and accurately. Finally, the precisely designed slide groove and slider structure ensure the accuracy and stability of the movement of the mobile mechanism 7 and improve the accuracy of the optical fiber connection. The design of the multi-layer slide groove increases the stability and reliability of the mobile mechanism 7 and reduces the shaking and deviation during the movement. The provision of the dustproof slide plate 706 protects the cleanliness of the interior of the connecting mechanism 1, reduces the risk of connection failure due to impurities such as dust, and prolongs the service life of the connector.

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

[0048] Specifically, in the above specific embodiment, when the power rack 701 of the mobile mechanism 7 moves with the moving slide 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 are meshed with the gear 105, the movement of the power rack 701 will drive the gear 105 to rotate, thereby moving the driven rack 104. 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 detection action of the self-test mechanism 2 and the linkage of the mobile mechanism 7. This gear 105 rack transmission structure realizes the reliable linkage between the mobile mechanism 7 and the self-test mechanism 2, and ensures the synchronization and accuracy of the optical fiber connection and detection action. Compared with the complex electronic control system, the pure mechanical transmission structure is more stable and reliable, reduces the probability of failure, reduces the maintenance cost, and improves the overall performance and service life of the optical fiber connector.
