Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber coupling testing equipment technology, and more specifically, to a device for rapid testing of the performance of ferrule assemblies with angles. Background Technology
[0002] In modern fiber optic communication systems, APC fiber ferrules, with their 8° beveled polished end faces, effectively reduce return loss and improve signal transmission quality, making them widely used in high-speed optical modules, fiber-to-the-home (FTTH), and data centers. However, the manufacturing and assembly precision requirements for APC ferrules are extremely high; their end-face angle, coupling efficiency, and end-face quality directly affect the transmission performance of optical signals. If the ferrule end-face angle is off, scratched, contaminated, or poorly connected, it can lead to increased optical signal loss, enhanced reflection, and even communication interruption.
[0003] Because the manufacturing process of typical APC modules is complex, and the subsequent matching products are of high value and require significant manufacturing challenges, it is necessary to test the coupling efficiency and angle of the modules. The conventional approach involves simulating device coupling, requiring a complete coupling device and trial coupling of each product. This method is cumbersome and inefficient, taking more than three minutes to test a single product, making the testing process excessively slow. Utility Model Content

[0008] A device for rapid performance testing of angled ferrule assemblies includes: two vertical fixed plates, two fixed rods fixedly connected between the two vertical fixed plates, a circular hole on one side of the outer surface of one of the vertical fixed plates, a first vertical moving plate slidably mounted on the two fixed rods, a transmissive reflective sheet fixedly embedded on one side of the outer surface of the first vertical moving plate, and a second vertical moving plate slidably mounted on the two fixed rods, a total reflective sheet fixedly embedded on one side of the outer surface of the second vertical moving plate.

[0014] 3. Beneficial effects
[0015] Compared with existing technologies, this utility model provides a device for rapid performance testing of ferrule assemblies with angles, which has the following beneficial effects:
[0016] This device for rapid performance testing of angled ferrule assemblies inserts an APC fiber optic ferrule into the center positioning elastic sleeve of one of the vertical fixing plates. By connecting the APC fiber optic ferrule to a visible light source, the light emitted from the ferrule passes through a transflector and a total reflection plate before being projected onto the outer surface of another vertical fixing plate. By moving two first sliding sleeves and two second sliding sleeves, the movement of the first and second vertical moving plates is controlled, respectively. Finally, the light spot on the other vertical fixing plate is observed. If the emitted light spot is bright, concentrated, and has clear edges, it indicates high coupling efficiency of the ferrule assembly. If the light spot is dim, diffuse, or has significant light leakage, it indicates low coupling efficiency. If the light spot is ring-shaped or off-center, it indicates that the ferrule end face is tilted. The quality of the ferrule assembly can be directly judged by the light spot shape, eliminating the need for complex instrument analysis, significantly shortening the testing time, greatly improving the detection efficiency of defective products, and also featuring a flexible and adjustable testing range. By adjusting the positions of the transflector and total reflection plates, the working environment of the actual connector can be simulated, enhancing the realism of the test.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0023] Example:
[0024] Please see Figures 1-3 A device for rapid performance testing of angled ferrule assemblies includes: two vertical fixed plates 1, two fixed rods 3 fixedly connected between the two vertical fixed plates 1, a circular hole on one side of the outer surface of one of the vertical fixed plates 1, a first vertical moving plate 4 slidably mounted on the two fixed rods 3, a transmissive reflective sheet 5 fixedly embedded on one side of the outer surface of the first vertical moving plate 4, a second vertical moving plate 7 slidably mounted on the two fixed rods 3, and a total reflective sheet 8 fixedly embedded on one side of the outer surface of the second vertical moving plate 7.
[0025] In a specific embodiment of this utility model, an APC fiber optic ferrule is inserted into a circular hole in one of the vertical fixing plates 1. A visible light source is connected to the APC fiber optic ferrule, allowing the light emitted from it to pass through the transflective plate 5 and the total reflection plate 8 before being projected onto the outer surface of the other vertical fixing plate 1. By moving the two first sliding sleeves 6 and the two second sliding sleeves 9, the movement of the first vertical moving plate 4 and the second vertical moving plate 7 is controlled, thereby achieving different detection accuracies at different distances. Finally, the light spot on the other vertical fixing plate 1 is observed. If the emitted light spot is bright and concentrated with clear edges, it indicates high coupling efficiency of the ferrule assembly; if the light spot is dim and weak, it indicates low coupling efficiency. If there is diffused light or obvious light leakage, it indicates that the coupling efficiency of the ferrule assembly is low. If the light spot is ring-shaped or eccentric, it indicates that the end face of the ferrule is tilted. The quality of the ferrule assembly can be directly judged by the light spot shape without the need for complex instrument analysis, which greatly shortens the detection time and significantly improves the detection efficiency of defective products. The detection efficiency has been increased from the original 180s / pcs to 5s / pcs (pcs is an abbreviation for Piece, which is a commonly used unit of measurement). The original detection range is also flexible and adjustable. By adjusting the position of the transflective sheet 5 and the total reflection sheet 8, the working environment of the actual connector is simulated, which improves the authenticity of the detection.
[0026] Specifically, two first sliding sleeves 6 are fixedly connected to one outer surface of the first vertical moving horizontal plate 4, and the two first sliding sleeves 6 are respectively slidably sleeved on the two fixed rods 3.
[0027] In this embodiment, the two first sliding sleeves 6 make the movement of the first vertically moving horizontal plate 4 more stable, serving as a guide and limiting element. The two first sliding sleeves 6 are made of self-lubricating material or metal sleeves with a lubricating layer to reduce sliding friction with the fixed rod 3.
[0028] Specifically, two second sliding sleeves 9 are fixedly connected to one outer surface of the second vertical moving horizontal plate 7, and the two second sliding sleeves 9 are respectively slidably sleeved on the two fixed rods 3.
[0029] In this embodiment, the two second sliding sleeves 9 make the movement of the second vertical moving cross plate 7 more stable, and play a guiding and limiting role. The two second sliding sleeves 9 are made of self-lubricating material or metal sleeves with a lubricating layer to reduce the sliding friction between them and the fixed rod 3.
[0030] Specifically, a central positioning elastic sleeve 2 is fixedly installed inside the round hole of the vertical fixing plate 1.
[0031] In this embodiment, the APC fiber optic ferrule is inserted inside the central positioning elastic sleeve 2 during coupling detection, achieving central positioning of the APC fiber optic ferrule. The central positioning elastic sleeve 2 provides flexible support for the APC fiber optic ferrule, protecting it from wear, displacement, or environmental damage. The central positioning elastic sleeve 2 absorbs mechanical stress through the deformation of the elastic material and is commonly found in cable connectors, optical device packaging, mechanical connectors, or electronic equipment to improve structural stability and durability.
[0032] Specifically, the reflective plate 5 is a projection glass plate with equidistant circular lines.
[0033] In this embodiment, the transflective sheet 5 is a transparent optical glass sheet with uniformly spaced concentric rings engraved on its surface. A series of precisely equidistant circular lines are printed on its surface. When light passes through the glass sheet and is projected onto the target surface, a clear ring-shaped light spot pattern is formed. This pattern can be used to detect optical system distortion, adjust focus, perform laser collimation calibration, or for teaching demonstrations.
[0034] Specifically, the total reflection sheet 8 is a total reflection glass sheet.
[0035] In this embodiment, the total reflection sheet 8 is made of high refractive index glass or coated glass, and its surface is specially treated to minimize absorption and scattering losses.
[0036] Working principle: The APC fiber optic ferrule is inserted into the center positioning elastic sleeve 2 of one of the vertical fixing plates 1. By connecting the APC fiber optic ferrule to a visible light source, the light emitted from the APC fiber optic ferrule passes through the transflective plate 5 and the total reflection plate 8, and is projected onto the outer surface of the other vertical fixing plate 1. By moving the two first sliding sleeves 6 and the two second sliding sleeves 9, the movement of the first vertical moving plate 4 and the second vertical moving plate 7 is controlled respectively, thereby achieving different detection accuracies at different distances. Finally, the light spot on the other vertical fixing plate 1 is observed. If the emitted light spot is bright and concentrated with clear edges, it indicates that the coupling efficiency of the ferrule assembly is high. If the light spot is dim, diffuse, or has obvious light leakage, it indicates that the coupling efficiency of the ferrule assembly is low. If the light spot is ring-shaped or eccentric, it indicates that the end face angle of the ferrule is tilted. The quality of the ferrule assembly can be directly judged by the shape of the light spot, without the need for complex instrument analysis, which greatly shortens the detection time and significantly improves the detection efficiency of defective products. It also has a flexible and adjustable detection range. By adjusting the position of the transflective plate 5 and the total reflection plate 8, the working environment of the actual connector can be simulated, improving the authenticity of the detection.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
