Description

Technical Field

[0001] This utility model relates to the field of ferrule installation technology, specifically to a PIN pin limiting tool for MT ferrule curing. Background Technology

[0002] In the manufacturing process of optical communication connectors, MT (Mechanical Transfer Ferrule) ferrules are widely used in the production of fiber optic ribbon connectors because they enable precise alignment and high-density splicing of multi-core optical fibers. Typically, both ends of a fiber optic ribbon need to be connected to two MT ferrules to form a complete fiber optic connection structure.

[0003] In existing assembly processes, the fiber ribbon is typically passed through the cover plate on the PIN pin before being bonded to the MT ferrule at both ends. If the PIN pin is installed after the fiber ribbon has been bonded, it cannot be inserted because the ferrule's inner hole is fixed by the bonded fiber. Therefore, this process must be completed before bonding.

[0004] However, during the fiber ribbon and ferrule curing process, the PIN pin is in a free-moving state because it has not yet been inserted into the specific ferrule hole. In this state, the PIN pin is prone to wobbling and slippage, which not only poses a risk of scratching the fiber ribbon and deforming the PIN pin, but may also cause it to become contaminated with adhesive from the ferrule during the curing process, resulting in adhesive residue on the fiber ribbon, poor product appearance, and affecting the subsequent fitting accuracy with the ferrule hole. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a PIN pin limiting fixture for MT ferrule curing. This solves the problem that in the existing technology, during the curing process of fiber ribbon and MT ferrule, the PIN pin is not yet fixed and is in a free-moving state, which easily leads to shaking and slippage. This not only poses the risk of scratching the fiber ribbon and deforming the PIN pin, but may also cause the fiber ribbon to stick to the ferrule during the curing process, resulting in poor product appearance and affecting the subsequent fitting accuracy with the ferrule hole.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pin limiting fixture for MT ferrule curing includes: A fixed frame has several mounting slots arranged in an array along its length on both sides, the mounting slots being used to install the ferrule body; A fixing plate is installed in the middle along the length of the fixing frame and has a through groove for accommodating the positioning pin of the PIN pin body.

[0007] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a fixing plate in the middle of the fixed frame and opening a through groove on the fixing plate to accommodate the positioning pin of the PIN pin body, the PIN pin body can be effectively limited during the curing stage of the fiber ribbon and the ferrule body. This not only prevents the PIN pin body from shaking or slipping during the curing process, thus avoiding deformation and scratching of the fiber ribbon, but also prevents the PIN pin body from contacting the glue on the surface of the ferrule body, which would cause contamination of the fiber ribbon or the PIN pin surface, thereby reducing the risk of fiber ribbon adhesive and poor product appearance.

[0008] Furthermore, the fixing plate has a mounting part with a mounting hole, and the fixing frame has a fixing hole, which is connected to the mounting hole for screws to pass through and lock.

[0009] Furthermore, a groove is provided at the bottom of the fixing frame, and the mounting part is recessed into the groove.

[0010] Furthermore, it also includes a magnetic strip, which is used to be installed on the upper part of the fixing frame to attract the cover plate of the PIN needle body.

[0011] Furthermore, a connecting hole is provided on one side of the fixing frame for installing a handle.

[0012] Furthermore, the inner diameter of the through groove is equal to or greater than the outer diameter of the positioning pin of the PIN pin body; Furthermore, the edges of the through groove have rounded corners. Attached Figure Description

[0014] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

They are not intended to limit the implementation conditions of this utility model and therefore have no substantial technical significance.

[0017] like Figure 1-4 As shown in the figure, this utility model embodiment proposes a PIN pin limiting tool for MT ferrule curing, including a fixing frame 30 and a fixing plate 40. The fixing frame 30 has a plurality of mounting grooves 31 arranged in an array along its length direction on both sides, and the mounting grooves 31 are used to install the ferrule body 10. The fixing plate 40 is installed in the middle of the fixing frame 30 along its length direction and has a through groove 401, which is used to accommodate the positioning pin 21 of the PIN pin body 20.

[0018] In this embodiment of the utility model, when in use, the ferrule body 10 to be cured is first installed in the mounting grooves 31 provided along the length direction on both sides of the fixed frame 30, and each ferrule body 10 is securely embedded in the corresponding mounting groove 31.

[0019] Subsequently, one end of the fiber optic ribbon is connected and inserted into the ferrule body 10 on one side of the fixing frame 30, and the other end passes through the cover plate 22 on the PIN pin body 20 and is connected to the ferrule body 10 on the other side, so that both ends of the fiber optic ribbon are fixedly connected to the corresponding ferrule body 10. Specifically, after one end of the fiber optic ribbon passes through the cover plate 22 on the PIN pin body 20, the positioning pin 21 below the PIN pin body 20 is aligned with the through slot 401 on the fixing plate 40 and inserted into the through slot 401 before the fiber optic ribbon is connected to the ferrule body 10 on the other side. In this way, the through slot 401 on the fixing plate 40 provides limiting support for the PIN pin body 20.

[0020] Then, in this state, the connection between the fiber optic ribbon and the ferrule body 10 can be cured. Since the positioning pin 21 of the PIN pin body 20 is confined in the through slot, the PIN pin body 20 will not shake, tip over, or slip during the curing process, thus preventing the PIN pin body 20 from scratching the fiber optic ribbon, deforming, or becoming contaminated with adhesive. Finally, after the fiber optic ribbons on both sides and the ferrule body 10 have cured, the operator can remove the ferrule bodies 10 and PIN pin bodies 20 from both sides in sequence. After removal, the PIN pin body 20 is inserted into the PIN hole of one of the ferrule bodies 10 to complete the positioning, thus obtaining the assembled MT connection assembly.

[0021] It is worth mentioning that, in this embodiment of the present invention, the inner diameter of the through groove 401 is equal to or greater than the outer diameter of the positioning pin 21 of the PIN body 20. Specifically, after one end of the optical fiber ribbon passes through the cover plate 22 on the PIN body 20, the positioning pin 21 on the PIN body 20 can be inserted vertically or at a certain angle into the through groove 401 for limiting and supporting. Preferably, the positioning pin 21 of the PIN body 20 is placed at an angle. By placing it at an angle, the optical fiber ribbon can pass through the cover plate 22 on the PIN body 20 at a gentler angle, which not only facilitates the subsequent connection of the ferrule body 10, but also reduces the bending degree and stress concentration of the optical fiber ribbon, effectively avoiding the risk of damage or scratches to the optical fiber ribbon. In addition, the edge of the through groove 401 is provided with a rounded corner structure. This rounded corner can also prevent the PIN body 20 from generating hard friction with the edge of the through groove 401 during insertion or removal, preventing the positioning pin 21 of the PIN body 20 from being scratched.

[0022] Specifically, such as Figure 2As shown in this embodiment of the invention, the fixing plate 40 has a mounting portion 41 with a mounting hole 411, and the fixing frame 30 has a fixing hole 32, which corresponds to and communicates with the mounting hole 411 for screws to pass through and lock. This design ensures a reliable connection between the fixing plate 40 and the fixing frame 30, keeping the fixing plate 40 stable during fiber optic ribbon curing and PIN pin positioning, preventing loosening or displacement, and thus guaranteeing the curing quality of the fiber optic ribbon. Furthermore, the bottom of the fixing frame 30 has a groove 33, into which the mounting portion 41 is recessed. This design ensures the flatness of the bottom of the fixing frame 30, facilitating its stable placement on the worktable.

[0023] It should be noted that, in the embodiments of this utility model, the fixing plate 40 is provided with multiple mounting parts 41, each mounting part 41 can be respectively embedded into the corresponding groove 33 at the bottom of the fixing frame 30, and locked with screws through mounting holes 411 and fixing holes 32. Thus, by providing multiple mounting parts 41, the connection between the fixing plate 40 and the fixing frame 30 is made more stable, providing more reliable support; and, as... Figure 3 As shown, a connecting hole 34 is provided on one side of the fixed frame 30. The connecting hole 34 is used to install a handle. For example, by passing one end of the handle through the connecting hole 34 and fixing it with bolts, nuts or pins, it can be tightly fitted with the fixed frame 30, making it convenient for the user to move the fixed frame 30 later.

[0024] Based on the above solutions, such as Figure 4 As shown in the embodiment of this utility model, a magnetic strip 50 is also included. The magnetic strip 50 is used to install on the upper part of the fixing frame 30 to attract the cover plate 22 of the PIN needle body 20. The magnetic strip 50 can also be magnetically attracted to the fixing frame 30. This arrangement ensures that the PIN needle body 20 is reliably fixed during the fiber optic ribbon insertion and curing process, preventing the cover plate 22 and positioning pin 21 from shaking or shifting, thus maintaining stability. Furthermore, it will not fall off after the fixing frame 30 is flipped, facilitating subsequent production operations.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
