Description
Technical Field
[0001] This utility model relates to the field of optical fiber testing technology, and in particular to a tensile testing device for a bundle combiner. Background Technology
[0002] The existing process for combining optical fibers involves arranging multiple optical fibers in a certain order, knotting them, heating and melting them to form a cone, then fusing it with the output optical fiber, encapsulating it, and forming the combining product.
[0003] During the process, the optical fiber is melted and then solidified, making it relatively fragile due to mechanical stress. Its packaging design and reliability testing are particularly important to ensure that the input and output optical fibers can withstand certain tensile forces and bending curvatures during product use, preventing internal breakage or snapping, thus ensuring good quality. The optical fiber straight-pull and side-pull devices are tooling designs for straight-pull and side-pull tests on the input and output optical fibers of the combiner, ensuring / screening products can withstand certain tensile force requirements and meet communication industry standards. Therefore, for straight-pull and side-pull tests on the input and output optical fibers of the combiner, those skilled in the art have designed a tensile testing device for the combiner. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tensile testing device for a laser beam combiner, which facilitates the straight and lateral tension tests on the optical fiber on the laser beam combiner.
[0005] The technical solution of this utility model is as follows: a tensile testing device for a bundle combiner, comprising a vertical plate, a clamping and fixing assembly disposed on the vertical plate, and a limiting clamping assembly. The limiting clamping assembly is disposed diagonally below the clamping and fixing assembly. The limiting clamping assembly includes a transition limiting plate. From top to bottom, the surface of the transition limiting plate is sequentially provided with an optical fiber winding disc, a wire clamping block group, and a weight. The transition limiting plate is slidably fitted onto the vertical plate. The clamping and fixing assembly includes a clamping fixing seat. The clamping fixing seat is provided with a limiting through groove. The rear sidewall of the clamping fixing seat is provided with a first positioning hole and a plurality of mounting holes arranged around the outside of the first positioning hole. The vertical plate is provided with a second positioning hole. After the first positioning hole and the second positioning hole are aligned, a positioning pin is inserted. The vertical plate is provided with an arc-shaped groove corresponding to the mounting hole. After the arc-shaped groove is aligned with the mounting hole, a fastener is inserted to fix the clamping fixing seat onto the vertical plate.
[0006] As can be seen from the above scheme, the clamping and fixing seat is used to limit and clamp the laser combiner through the limiting through groove, the fiber winding disc is used to wind the fiber, the clamping block group is used to clamp the end of the fiber to ensure the stability of the fiber during the test, and the weight is used to drive the adapter limiting plate to move down through its own gravity to provide downward tension for the fiber. When the clamping and fixing seat rotates, the fastener slides in the arc groove; when the clamping and fixing seat is adjusted to the required angle, the fastener extends out of the arc groove, passes through the mounting hole and tightens to lock the clamping and fixing seat to the upright plate. When the limiting through groove is set vertically downward, it is used to test the straight pull performance of the laser combiner fiber. When the angle of the clamping and fixing seat is adjusted so that the laser combiner is placed horizontally, it is used to test the lateral pull performance of the fiber on the laser combiner, thereby performing a tensile test on the laser combiner fiber.
[0007] The upright plate is fixed to the base plate, which is equipped with a support assembly. The support assembly includes a connecting rod and a support rod horizontally mounted on the connecting rod. The upright plate is connected to the base plate, which has several limiting holes. Connecting inserts corresponding to the limiting holes are located at the bottom of the connecting rod. Therefore, the support rod is used to support the weight, and the connecting inserts change the support height of the support rod by being inserted into different limiting holes.
[0008] The clamping and fixing assembly further includes fastening limiting members inserted on both sides of the limiting through groove, with the ends of the fastening limiting members extending out of the limiting through groove. Thus, it can be seen that the fastening limiting members on both sides...
[0009] The clamping block group includes two sets of clamping blocks symmetrically arranged at the bottom of the optical fiber winding disc, and the clamping blocks are provided with clamping grooves.
[0010] The clamping block is made of a soft material. Therefore, the clamping block is used to prevent damage when clamping the end of the optical fiber.
[0011] A slide rail is provided vertically on the upright plate, and the adapter limiting plate slides in conjunction with the slide rail via a slider. Therefore, the adapter limiting plate is slidably connected to the upright plate via the slide rail, allowing the weight of the weight to pull the optical fiber held on the adapter limiting plate downwards.
[0012] The adapter limiting plate is equipped with a load-bearing rod, and the weights are fitted onto the load-bearing rod. Therefore, weights of different weights are fitted or stacked on the load-bearing rod to apply different tensile forces, thereby better testing the tensile performance of the bundle combiner.
[0013] The arc-shaped groove includes an upper arc-shaped groove and a lower arc-shaped groove that are symmetrically arranged. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] like Figures 1 to 4 As shown, this utility model is a tensile testing device for a bundle combiner, including a vertical plate 1, a clamping and fixing assembly and a limiting clamping assembly disposed on the vertical plate 1. The limiting clamping assembly is disposed diagonally below the clamping and fixing assembly. The limiting clamping assembly includes a transition limiting plate 3. From top to bottom, the surface of the transition limiting plate 3 is sequentially provided with an optical fiber winding disc 4, a wire clamping block assembly and a weight 10. A load-bearing rod 31 is disposed on the transition limiting plate 3, and the weight 10 is sleeved on the load-bearing rod 31. The transition limiting plate 3 is slidably fitted onto the vertical plate 1. The clamping and fixing assembly... The device includes a clamping and fixing base 5, which has a limiting through groove 51. The rear side wall of the clamping and fixing base 5 has a first positioning hole 52 and a plurality of mounting holes 53 arranged around the outside of the first positioning hole 52. The upright plate 1 has a second positioning hole 11. After the first positioning hole 52 is aligned with the second positioning hole 11, a positioning pin 6 is inserted. The upright plate 1 has an arc-shaped groove 12 corresponding to the mounting hole 53. After the arc-shaped groove 12 is aligned with the mounting hole 53, a fastener 7 is inserted to fix the clamping and fixing base 5 on the upright plate 1.
[0020] The upright plate 1 is fixed to the base plate 2, and a support assembly is provided on the base plate 2. The support assembly includes a connecting rod 21 and a support rod 22 horizontally arranged on the connecting rod 21. The upright plate 1 is connected to the base plate 2, and the base plate 2 is provided with a plurality of limiting holes 20. The bottom of the connecting rod 21 is provided with a connecting plug corresponding to the limiting hole 20. In this embodiment, the connecting rod 21 is inserted into the corresponding limiting hole 20 through the connecting plug at the bottom. The connecting rod is inclined, and the support rod 22 is obliquely erected on the base plate 2 to support the weight 10.
[0021] The clamping and fixing assembly also includes fastening limiting members 54 inserted on both sides of the limiting through groove 51, with the ends of the fastening limiting members 54 extending out of the limiting through groove 51.
[0022] The clamping block assembly includes two sets of clamping blocks 8 symmetrically arranged at the bottom of the optical fiber winding disc 4, and each clamping block 8 is provided with a clamping groove 81. The clamping blocks 8 are made of soft material; in this embodiment, the clamping blocks 8 are sponge blocks, and the clamping grooves 81 are vertically arranged.
[0023] The arc-shaped groove 12 includes an upper arc-shaped groove portion and a lower arc-shaped groove portion symmetrically arranged. In this embodiment, the upper arc-shaped groove portion and the lower arc-shaped groove portion are arranged symmetrically from top to bottom, and the width of the arc-shaped groove 12 is greater than the diameter of the mounting hole 53.
[0024] The working process of this utility model is as follows: When performing the direct pull test, the laser beam combiner is placed on the limiting slot 51 on the clamping and fixing seat 5 and fastened and limited by the fastening limiting parts 54 on both sides. The weight of the fixed weight required by the direct pull standard (e.g., 900g) is suspended on the load-bearing rod 31, and the connecting rod 21 is inserted to stabilize the weight 10 by the support rod 22. The fiber at the tail end of the beam combiner is wound on the fiber winding disc 4 and wound several times. Then, the tail end of the fiber is clamped and fixed in the clamping slot 81 of the clamping block 8 to achieve clamping and limiting. The support rod 22 is removed, and the weight 10 falls, causing the adapter limiting plate 3 to move down, thereby pulling the fiber down. The fiber tension test of the beam combiner corresponds to the weight of the weight 10. The test is conducted for a certain period of time (e.g., 10s) to see if the fiber is broken, and to determine whether the direct pull result is qualified.
[0025] During the lateral pull test, the clamping and fixing seat 5 is rotated 90 degrees, the arc groove 12 is aligned with the corresponding mounting hole 53, the fastener 7 is inserted and tightened, and the clamping and fixing seat 5 is fixed on the vertical plate 1, so that the optical fiber is nearly perpendicular to the optical fiber winding disc 4. The weight of the weight (e.g., 300g) and the test time (e.g., 5s) are the same as those for the straight pull test.
[0026] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
