Description

Technical Field

[0001] This utility model relates to the field of fiber optic array technology, and in particular to a positioning fixture for a high-precision fiber optic array collimator. Background Technology

[0002] A fiber optic array (FA) is an array formed by mounting a bundle of optical fibers or a strip of optical fibers at specified intervals on a V-groove substrate. With the rapid development of communication technology and the explosive growth of practical applications, the use of optical fibers is increasing. Fiber optic array units are mainly used for the input and output of light waves in optical communication devices. They are important components of fiber optic array devices such as planar optical waveguides, PLCs, and optical modules. They are widely used for data transmission via optical fibers. To ensure smooth optical signal transmission, each fiber in the fiber optic array needs to be aligned with the channels in the optical waveguide device. Therefore, it is required that the fiber cores of the fiber optic array be basically located in the same plane with a defined spacing.

[0003] Existing fiber optic arrays cannot be quickly bundled during use, and the installation process is extremely complex and cumbersome. Furthermore, friction between components during fiber movement can easily cause damage. Therefore, a new type of fiber optic array is proposed. Existing fiber optic arrays come in various fiber spacing models, some with 127µm and others with n*250µm, requiring multiple array types that are not interchangeable, causing significant difficulties and waste in production and installation. Simultaneously, the equipment and standards compatible with existing optical cables are somewhat outdated, resulting in numerous and messy optical cables and pigtails within power station cabinets, with labels easily detached. There are also no corresponding protective devices for the pigtails, which may cause other pigtails to break during operation, posing a significant threat to the safe and stable operation of the power station.

[0004] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a positioning fixture for a high-precision fiber optic array collimator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: A positioning fixture for a high-precision fiber optic array collimator includes a frame and several positioning templates. Each positioning template is sequentially arranged within the frame, and each positioning template has a mounting groove. An optical fiber is arranged inside the mounting groove, and an optical fiber ribbon is fixedly connected to one end of the optical fiber. A fixing plate for fixing the pigtail of the optical fiber ribbon is fixedly connected to the end of the optical fiber ribbon away from the optical fiber. The number of fixing plates is the same as the number of positioning templates. The frame is provided with tightening bolts for tightening each positioning template, and the fixing plates are connected to each other by fixing bolts.

[0007] Furthermore, it also includes a substrate disposed within the frame, with one end of the substrate disposed within the frame and the other end disposed on each of the fixing plates.

[0008] Furthermore, each of the fixed plates is provided with a through slot for placing the optical fiber pigtail, and each optical fiber pigtail is sequentially arranged in the corresponding through slot.

[0009] Furthermore, a protective rubber pad is laid on the surface between the substrate and the adjacent positioning template, and a protective rubber pad is laid on the surface between two adjacent positioning templates.

[0010] Furthermore, the gap between the bare fiber portion of the optical fiber and the corresponding mounting groove is filled with adhesive.

[0011] Furthermore, both the substrate and the frame are made of acrylic material.

[0012] Furthermore, the optical fiber is a metallic optical fiber.

[0013] By adopting the aforementioned design scheme, the beneficial effects of this utility model are: 1. By setting up the frame and positioning template, and connecting the frame and positioning template with the threaded bolts, the system is reinforced and stabilized to prevent displacement or loosening of the optical fiber during movement. The rubber pads prevent friction between the restraints during optical fiber movement, which could cause damage to the object. Multiple positioning templates are also provided, and the spacing of the installation grooves can be changed by changing the positioning templates to adapt to various types of optical fiber arrays. 2. By fixing the fiber optic pigtails with a fixing plate, the corresponding fiber optic pigtails can be protected. The fixing plate can protect the fiber optic unit and the fiber optic pigtails. This device can be placed under the floor. When the operator is working, he will only come into contact with the fixing plate or substrate and will not damage the fiber optic pigtails.

Each positioning template 2 is arranged sequentially inside the frame 1, and each positioning template 2 has several mounting grooves 21. Each mounting groove 21 contains an optical fiber 3. One end of the optical fiber 3 is fixedly connected to an optical fiber ribbon 31. The end of the optical fiber ribbon 31 away from the optical fiber 3 is fixedly connected to a fixing plate 4 for fixing the pigtail of the optical fiber ribbon 31. The number of fixing plates 4 is the same as the number of positioning templates 2. The frame 1 is provided with tightening bolts (not shown in the figure) for tightening each positioning template 2.

[0017] Furthermore, it also includes a base plate 5 disposed within the frame 1, with one end of the base plate 5 disposed within the frame 1 and the other end disposed on each fixing plate 4. In this embodiment, the frame 1, the base plate 5, and each positioning template 2 are reinforced with tightening bolts to ensure stability and prevent displacement or loosening of the optical fiber 3 during its movement. A protective rubber pad (not shown in the figure) is laid on the surface between the base plate 5 and the adjacent positioning template 2, and a protective rubber pad is laid on the surface between two adjacent positioning templates 2. The protective rubber pad is to prevent friction between the restraints when the optical fiber 3 moves, which could cause damage to the object.

[0018] Furthermore, each fixing plate 4 is provided with a through slot 41 for placing the pigtail of the optical fiber ribbon 31, and the pigtail of each optical fiber ribbon 31 is arranged in the corresponding through slot 41 in sequence.

[0019] Furthermore, both the tightening bolts and the fixing bolts are coated with an anti-oxidation coating to prevent rust and increase their service life.

The optical fiber 3 passes through the mounting groove 21 of the positioning template 2, and the pigtail of the optical fiber ribbon 31 passes through the through groove 41 of the fixing plate 4. Manually rotate the tightening bolt and fixing bolt to connect and fix the frame 1, substrate 5 and positioning template 2 to prevent the optical fiber from moving. At the same time, multiple positioning templates 2 are provided. By changing the positioning template 2, the spacing of the mounting groove 21 can be changed to adapt to various types of optical fiber 3 arrays.
