Description
Technical Field
[0001] The present application relates to the field of optical communication testing technology, and in particular to an insertion-return loss test docking tool. Background Art
[0002] AOC (Active Optical Cable) is a high-speed transmission cable that integrates optoelectronics and optical fiber technology. AOC is mainly used in data centers, supercomputing centers, high-performance computing (HPC), and other scenarios that require high-speed data transmission. When producing AOC products, it is necessary to perform insertion loss tests on AOC products to evaluate the performance of optical fiber connections.
[0003] Insertion loss test is usually done manually by connecting the workpiece to the standard line for loop connection test. It is very easy to scratch and damage the PIN hole during connection, thus causing the workpiece to be scrapped, or the end face of the standard line or the workpiece may be damaged during the test process, so that the worker needs to grind the end face of the standard line or the workpiece after completing the workpiece test, resulting in low test efficiency of the workpiece.
[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content
[0005] The purpose of this application is to improve the test efficiency of workpiece insertion loss test.
[0006] The above-mentioned technical purpose of the present application is achieved through the following technical solutions: an insertion-return loss test docking tool, comprising a base plate, a standard line positioning block is provided on the base plate for positioning the standard line; a slide rail is provided on the base plate, a slider is provided on the slide rail, and a test line positioning block is provided on the slider for positioning the test line; the test line positioning block is moved toward or away from the standard line positioning block by sliding the slider on the slide rail; the standard line positioning block is provided with an installation groove, and a standard line connector is provided in the installation groove; a limit block is provided on the standard line positioning block, and an elastic member is provided on the limit block, and one end of the elastic member away from the limit block abuts against the standard line connector, and the standard line connector slides in the installation groove toward or away from the test line positioning block, and the limit block and the standard line connector cooperate to release or squeeze the elastic member.
[0007] By adopting the above technical solution, the standard line positioning block and the test line positioning block are used to position the standard line and the test line respectively, ensuring that their positions during the test process are accurate. Through the smooth sliding of the slider along the slide rail, the test line positioning block can be accurately aligned with the standard line positioning block to ensure the accuracy of docking. During the docking process, the standard line connector can slide smoothly in the installation groove, and the limit block and the elastic member are squeezed or released to achieve flexible control of docking. It effectively prevents excessive force during docking, reduces end face damage caused by collision, and improves the service life of the product and the standard line. The elastic member ensures that the standard line connector is always in the proper position and tightness during the docking process by providing a stable preload. The presence of preload can not only prevent loosening, but also absorb some slight vibrations and shocks, further protecting the docking end face. Due to the smoothness and accuracy of the docking process, the risk of accidental damage to the optical fiber end face during operation is reduced, and the safety and reliability of operation are improved. The simplified operation steps and intuitive sliding adjustment mechanism can greatly reduce the probability of error.
[0008] Optionally, the standard line positioning block and the test line positioning block can be connected by magnetic attraction.
[0009] By adopting the above technical solution, the magnetic connection allows the standard line positioning block and the test line positioning block to be automatically aligned and quickly adsorbed, simplifying the docking process and reducing human errors. Even novice operators can easily achieve accurate docking and improve overall test efficiency. The magnetic connection achieves quick and easy docking, avoiding the friction and impact that may be caused by traditional mechanical connection methods, reducing damage to the end faces of the standard line and test line, and thus extending their service life. The magnetic connection not only provides the initial docking force, but also provides a stable pre-tightening force by properly designing the magnetic force size, ensuring a tight connection between the positioning blocks during the docking process, avoiding the rebound of the elastic part causing the test line positioning block to loosen or detach from the standard line positioning block, and improving the stability and reliability of the test.
[0010] Optionally, a through slot is recessed in the standard line positioning block, the limit block is disposed in the through slot, a fixing rod is disposed in the through slot, the fixing rod passes through the limit block, and the limit block slides in the through slot along the fixing rod.
[0011] By adopting the above technical solution, by setting a through slot and a fixing rod in the standard line positioning block, the limit block can slide smoothly along the fixing rod in the through slot. This design provides precise docking control, ensures that the elastic part is accurately deformed to provide a preset elastic force to buffer the docking impact of the test line connector, and reduces the possibility of damage to the workpiece.
[0012] Optionally, a spring force adjustable channel is hollowed out in the standard line positioning block, and the spring force adjustable channel is connected to the through slot.
[0013] By adopting the above technical solution, the spring force adjustable channel allows the compression of the spring to be adjusted, thereby controlling the size of the preload. This allows appropriate preload to be provided according to actual needs during the docking process, ensuring a stable connection between the standard line connector and the test line connector, avoiding loosening or detachment, and improving the reliability of docking. By adjusting the spring force to adapt to different docking requirements, end face damage caused by excessive or insufficient preload during the docking process can be prevented. Appropriate preload can effectively protect the optical fiber end face, reduce wear, extend the service life of the standard line and test line, and reduce maintenance and replacement costs. The design of the spring force adjustable channel allows the docking tool to flexibly adapt to AOC products of different specifications and types. Operators can easily adjust the spring force according to specific test requirements to achieve the best docking effect in different test scenarios, significantly improving the flexibility and adaptability of the test.
[0014] Optionally, the slide rail is a linear guide rail.
[0015] By adopting the above technical solutions, the linear guide rail ensures the smooth sliding and accurate positioning of the slider on the guide rail through its high-precision and high-rigidity design. It significantly improves the accuracy and stability of the test line and the standard line when docking, reduces the test error caused by the docking position offset, and ensures the reliability and consistency of the insertion loss test. The linear guide rail design enables the slider to move quickly and smoothly along the guide rail, simplifying the operation process of docking the test line and the standard line. The operator can more conveniently adjust the slider position, quickly complete the docking process, and significantly improve the test efficiency.
[0016] Optionally, a limiting column is provided on the bottom plate.
[0017] By adopting the above technical solution, the limit column can effectively prevent the slider from excessively moving on the slide rail, ensuring that the slider slides smoothly within the specified range. This design can prevent the slider from moving out of the track or hitting the edge of the bottom plate, thereby protecting the test line, standard line, slide rail and other components, and reducing damage and wear caused by excessive movement.
[0018] Optionally, a cover plate is provided on the standard line positioning block.
[0019] By adopting the above technical solution, the cover plate can effectively cover the standard line positioning block and protect the standard line connector from pollution, dust and physical damage from the external environment. This can keep the standard line connector clean and intact, and avoid affecting the test accuracy and reliability due to contact with pollutants or accidental impact. The cover plate is covered after the standard line connector is positioned, which can fix the position of the standard line connector to prevent displacement or loosening during the test. This design can ensure consistent conditions for each test, improve the stability and repeatability of the test, and reduce test errors caused by changes in the connector position.
[0020] Optionally, a side of the standard line positioning block close to the test line positioning block is concavely provided with a space-avoiding groove.
[0021] By adopting the above technical solution, the design of the air-avoiding groove provides additional space to avoid interference between the standard line connector and the test line connector during docking. This helps to ensure that the docking parts are accurately docked without restrictions, thereby improving the docking accuracy and test consistency. The air-avoiding groove can reduce physical contact and friction during the docking process, and avoid wear of the standard line connector and the test line connector due to extrusion or collision. This can effectively protect the connector end face, extend the service life of the test line and the standard line, and reduce maintenance and replacement costs.
[0022] In summary, this application has at least the following beneficial effects:
[0023] 1. The standard line positioning block and the test line positioning block are used to position the standard line and the test line respectively, ensuring that they are positioned accurately during the test process. Through the smooth sliding of the slider along the slide rail, the test line positioning block can be accurately aligned with the standard line positioning block to ensure the accuracy of docking. During the docking process, the standard line connector can slide smoothly in the installation groove, and the limit block and the elastic member are squeezed or released to achieve flexible control of docking. It effectively prevents excessive force during docking, reduces end face damage caused by collision, and improves the service life of the product and standard line. The elastic member ensures that the standard line connector is always in the proper position and tightness during the docking process by providing a stable preload. The presence of preload can not only prevent loosening, but also absorb some slight vibrations and shocks, further protecting the docking end face. Due to the smoothness and accuracy of the docking process, the risk of accidental damage to the fiber end face during operation is reduced, and the safety and reliability of operation are improved. The simplified operating steps and intuitive sliding adjustment mechanism can greatly reduce the probability of error.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.
[0032] In this embodiment, refer to Figure 1-2 , an insertion-return loss test docking tool, includes a base plate 1, which serves as the basic support component of the entire tool and provides a stable installation platform. A standard line positioning block 2 is provided on the base plate 1, which is used to accurately position and limit the standard line 3 to ensure the stability of the standard line 3 during the test. At the same time, a slide rail 4 is also provided on the base plate 1, and a slider 5 is installed on the slide rail 4, and the slider 5 can slide smoothly along the slide rail 4. A test line positioning block 6 is provided on the slider 5, which is used to fix the test line 7 and move with the slider 5. By sliding the slider 5 on the slide rail 4, the test line positioning block 6 can be driven to move in a direction close to or away from the standard line positioning block 2, thereby realizing the precise docking of the test line 7 with the standard line 3.
[0033] A mounting groove 8 is provided on the standard line positioning block 2 for placing a standard line connector 9. The standard line connector 9 is installed in the mounting groove 8 and can be docked with the test line 7 to form a complete test loop. In addition, a limit block 10 is also provided on the standard line positioning block 2, and an elastic member 11, such as a spring, is assembled on the limit block 10. One end of the elastic member 11 is connected to the limit block 10, and the other end abuts against the standard line connector 9. When the test line positioning block 6 approaches the standard line positioning block 2, the test line 7 and the standard line 3 are docked, and the standard line connector 9 will slide in the mounting groove 8 in the direction away from the test line 7. At this time, the elastic member 11 is compressed and accumulates elastic potential energy. When it is necessary to separate the test line 7 and the standard line 3, the elastic member 11 will release its accumulated elastic potential energy and push the standard line connector 9 to move in the direction away from the test line 7, thereby achieving smooth and lossless separation.
[0034] The test line positioning block 6 includes a workpiece branch end positioning block and a workpiece long and short fiber positioning block, which respectively fix the branch end and the long fiber or short fiber part of the workpiece. The operator holds the test line positioning block 6 to move the slider 5 along the slide rail 4 to accurately connect the joint part of the test line 7 with the standard line joint 9 on the standard line positioning block 2.
[0035] Through the precise cooperation between the slider 5 and the slide rail 4, the test line positioning block 6 is precisely moved, thereby controlling the docking and separation process of the test line 7 and the standard line 3. At the same time, the elastic effect of the elastic member 11 is utilized to ensure the stability and non-destructiveness during the docking and separation process, thereby effectively improving the test efficiency and reducing the product scrap rate.
[0036] In this embodiment, refer to Figure 1 , a magnetic connection structure is added between the standard line positioning block 2 and the test line positioning block 6. Specifically, magnets are installed on the opposite surfaces of the standard line positioning block 2 and the test line positioning block 6. When the two are close to each other, the magnets attract each other, so that the standard line positioning block 2 and the test line positioning block 6 are tightly connected together. Through the magnetic connection, the stability after docking can be further enhanced and the accuracy of the test data can be improved.
[0037] Reference Figure 2-3 , this embodiment further improves the standard line positioning block 2. Specifically, a through groove 12 is concavely provided in the standard line positioning block 2, and the limit block 10 is arranged in the through groove 12. A fixing rod 13 is also provided in the through groove 12, and the fixing rod 13 is passed through the limit block 10, so that the limit block 10 can slide stably in the through groove 12 along the fixing rod 13. This structural design not only ensures the stability of the sliding of the limit block 10, but also simplifies the overall structure, which is convenient for manufacturing and maintenance.
[0038] Reference Figure 3 , a spring force adjustable channel 14 is further provided on the standard line positioning block 2. The spring force adjustable channel 14 is connected to the through slot 12, allowing the operator to change the elastic force of the elastic member 11 through the adjustment member in the spring force adjustable channel 14. For example, a threaded structure is provided in the spring force adjustable channel, through which a bolt is passed, and the bolt abuts against the limit block 10, so as to adjust the initial position of the limit block 10 in the through slot 12. In this way, the force in the docking and separation process can be adjusted according to actual needs to adapt to test lines 7 of different specifications or requirements, thereby broadening the application range of the tool.
[0039] In this embodiment, the slide rail 4 is optimized. Specifically, the slide rail 4 adopts a linear guide rail, which has the advantages of high precision, high rigidity, high load capacity, etc., and can ensure the stability and precision of the slider 5 during the sliding process. At the same time, the linear guide rail also has the characteristics of simple structure and easy installation, which helps to reduce the manufacturing cost and maintenance difficulty of the tool.
[0040] In this embodiment, refer to Figure 1 , a limit column 15 is provided on the bottom plate 1, preferably the limit column 15 is provided on the side of the slide rail 4, and the limit column 15 can effectively prevent the slider 5 from excessively moving on the slide rail 4, ensuring that the slider 5 slides smoothly within the specified range. This design can prevent the slider 5 from moving out of the track or hitting the edge of the bottom plate 1, thereby protecting the test line 7, the standard line 3, the slide rail 4 and other components, and reducing damage and wear caused by excessive movement.
[0041] In this embodiment, refer to Figure 1-2 A cover plate 16 is provided on the standard line positioning block 2, and the cover plate 16 can be stably installed on the standard line positioning block 2 by pins, etc. The cover plate 16 can effectively cover the standard line positioning block 2, preventing the spring and the standard line connector 9 from tilting and docking inaccurately, and at the same time can protect the standard line 3 and the standard line connector 9 from pollution, dust and physical damage from the external environment.
[0042] In this embodiment, refer to Figure 4 The standard line positioning block 2 is provided with an air avoidance groove 17 on one side close to the test line positioning block 6. During the docking process between the standard line 3 and the test line 7, an air avoidance groove 17 is designed in the front end positioning groove of the standard line positioning block 2 to prevent the test line 7 connector from directly colliding with the standard line positioning block 2, thereby reducing the possibility of collision damage to the workpiece.
[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
