Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber threading, in particular to an optical fiber threading auxiliary device. Background Art
[0002] The production process of optical fiber jumpers is a complex and delicate technological process, which involves multiple steps and strict quality control. Its main purpose is to add optical fiber connectors (optical fiber plugs) to the ends of optical fiber lines. The production of optical fiber jumpers usually includes steps such as cutting optical cables, threading loose parts, stripping fibers, injecting glue, threading fibers, curing glue, and grinding end faces. Most of these steps rely on manual operations.
[0003] When threading an optical fiber, a worker needs to hold the optical fiber in one hand and pick up the optical fiber ferrule with tweezers in the other hand, and insert and pass the optical fiber through the optical fiber ferrule, thus completing the fiber threading process. In actual production, because the optical fiber core itself is too thin and fragile, with a diameter of only 0.125 mm, and the minimum diameter of the inner hole of the ferrule is only 0.13 mm, the fiber threading is difficult, and the fiber threading efficiency completely depends on the proficiency and concentration of the worker, resulting in a relatively low overall efficiency of the fiber threading step. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an optical fiber threading auxiliary device to solve the above problems existing in the prior art.
[0005] To solve the above problems, the utility model provides an optical fiber threading auxiliary device, which includes a base. One end of the upper surface of the base is fixedly provided with a clamping base, and the clamping base can fix the coating layer of the optical fiber. A fiber threading sliding seat and a ferrule sliding seat are slidably arranged on the upper surface of the base. The fiber threading sliding seat is used to pass through and guide the core of the optical fiber, and the ferrule sliding seat is used to place the optical fiber ferrule. The fiber threading sliding seat and the ferrule sliding seat are sequentially far away from the clamping base, and the fiber threading sliding seat and the ferrule sliding seat tend to move away from the clamping base under the influence of the spring elastic force. When the core passes through the fiber threading sliding seat and the coating layer is fixed to the clamping base, inserting the ferrule sliding seat close to the clamping base will cause the core to be inserted into the optical fiber ferrule.
[0006] The optical fiber threading auxiliary device provided by the utility model further has the following technical features:
[0007] Further, a conical groove with an opening facing the clamping base is arranged on the fiber threading sliding seat, and a core groove through which the core can pass is also arranged. The core groove is coaxially arranged with the conical groove, and the core groove communicates with the conical groove through the vertex of the conical groove.
[0008] Further, a cylindrical groove for inserting the ferrule base of the optical fiber ferrule is arranged on the outer periphery of the core groove. The opening of the cylindrical groove faces the ferrule sliding seat, and the cylindrical groove is coaxially arranged with the core groove.
[0009] Furthermore, the fiber-passing sliding seat includes a sliding seat base and a sliding seat upper cover that are hinged to each other. Correspondingly, the conical groove and the cylindrical groove are divided into upper and lower parts. The fiber core groove is provided on the sliding seat base, and the upper end of the fiber core groove is covered by the sliding seat upper cover.
[0010] Furthermore, when the ferrule sliding seat abuts against the fiber-passing sliding seat, there is a gap between the end face of the ferrule base and the end face of the cylindrical groove.
[0011] Furthermore, a semi-cylindrical clamping groove is provided on the clamping base, and the clamping groove is coaxial with the conical groove.
[0012] Furthermore, the clamping base is provided with a convex block that can be embedded in the conical groove towards the fiber-passing sliding seat, and the cross-section of the coating layer is parallel to the end of the convex block.
[0013] Furthermore, a pressing plate is hinged on the clamping base and the ferrule sliding seat, and the pressing plate is used to fix the coating layer and the fiber ferrule.
[0014] Furthermore, a sliding seat groove is provided on the upper surface of the base, a sliding rod groove is provided in the sliding seat groove, a sliding rod is provided in the sliding rod groove, and sliding blocks that can pass through the sliding rod are provided at the bottom ends of the fiber-passing sliding seat and the ferrule sliding seat, and a spring is sleeved on the sliding rod.
[0015] Furthermore, the length of the sliding rod groove where the sliding block of the fiber-passing sliding seat is located is less than the length of the sliding rod groove where the sliding block of the ferrule sliding seat is located.
[0016] The utility model has the following beneficial effects: The device uses the fiber-passing sliding seat to guide the fiber core when passing through, and then combines with the ferrule sliding seat to quickly and conveniently insert the fiber core into the fiber ferrule, without manual alignment for fiber passing, and the fiber passing efficiency is relatively high.

Specific embodiments
[0027] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other.
[0028] As Figures 1 to 9 In the embodiment of the optical fiber threading auxiliary device of the present utility model shown in the figure, the optical fiber threading auxiliary device includes a base 1, a clamping base 2 is fixedly provided at one end of the upper surface of the base 1, and an optical fiber threading slide 3 and a ferrule slide 4 are slidably provided on the upper surface of the base 1; the clamping base 2 can fix the coating layer 51 of the optical fiber 5, and the optical fiber threading slide 3 is used to pass through the fiber core 52 of the optical fiber 5 to guide and straighten the fiber core 52 and position it, and the ferrule slide 4 is used to place the fiber optic ferrule 6.
[0029] In the production process of optical fiber jumpers, after the optical fiber 5 is stripped of the coating, a cross-section of the coating layer 51 exists, so the fiber core 52 can extend out of the coating layer 51; the fiber optic ferrule 6 (taking the SC ferrule as an example in the figure) includes a ferrule body 62 (usually a ceramic ferrule) and a ferrule base 61, and the process of threading the fiber core 52 is: the fiber core 52 passes through the ferrule base 61 and further passes through the ferrule body 62, and extends out from the end of the ferrule body 62.
[0030] In this embodiment, an optical fiber threading slide 3 and a ferrule slide 4 are slidably provided on the upper surface of the base 1. The optical fiber threading slide 3 and the ferrule slide 4 are sequentially away from the clamping base 2, and the optical fiber threading slide 3 is arranged between the clamping base 2 and the ferrule slide 4; the optical fiber threading slide 3 and the ferrule slide 4 are affected by the elastic force of the spring 14 and tend to move away from the clamping base 2.
[0031] During use, the worker passes the core 52 with the coating layer 51 removed through the fiber-passing sliding seat 3. The fiber-passing sliding seat 3 is used to straighten and guide the core 52, and then the coating layer 51 is fixed on the clamping base 2. At this time, a section of the core 52 leaks out from the fiber-passing sliding seat 3. Due to the guiding effect of the fiber-passing sliding seat 3, the core 52 is coaxial with the fiber ferrule 6 on the ferrule sliding seat 4 at this time. At this time, the ferrule sliding seat 4 can be manually or electrically moved closer to the fiber-passing sliding seat 3. After the core 52 is inserted into the ferrule 6, the ferrule sliding seat 4 further abuts against the fiber-passing sliding seat 3 and drives the fiber-passing sliding seat 3 to continue approaching the clamping base 2 until the core 52 is completely inserted into the fiber ferrule 6 and extends out from the other end of the fiber ferrule 6, and then the fiber-passing process is completed.
[0032] For the optical fiber fiber-passing auxiliary device of the present utility model, the fiber-passing sliding seat 3 is used to guide the core 52 when passing through, and combined with the ferrule sliding seat 4, the core 52 can be quickly and conveniently inserted into the fiber ferrule 6 without manual alignment for fiber passing, and the fiber-passing efficiency is relatively high.
[0033] In an embodiment of the present application, preferably, the coating layers 51 of multiple optical fibers 5 can be fixed on the clamping base 2. Correspondingly, the fiber-passing sliding seat 3 can pass through multiple cores 52, and the ferrule sliding seat 4 can hold multiple fiber ferrules 6, and the fiber-passing work of multiple optical fibers 5 can be carried out simultaneously, further improving the work efficiency.
[0034] In an embodiment of the present application, preferably, as Figure 7 shown, the fiber-passing sliding seat 3 is provided with a conical groove 301 with an opening facing the clamping base 2, and a core groove 302 through which the core 52 can pass is also provided. The core groove 302 is coaxially arranged with the conical groove 301, and the core groove 302 communicates with the conical groove 301 through the vertex of the conical groove. The conical groove 301 and the core groove 302 play a guiding role for the core 52. Among them, the conical groove 301 facilitates the core 52 to penetrate into the core groove 302, and the core groove 302 needs to have a certain length so that the core 52 is guided and straightened after passing through the core groove 302 to facilitate further fiber-passing work.
[0035] In an embodiment of the present application, preferably, as Figure 7 、 Figure 8 shown, a cylindrical groove 303 into which the ferrule base 61 of the fiber ferrule 6 can be inserted is provided on the outer periphery of the core groove 302. The opening of the cylindrical groove 303 faces the ferrule sliding seat 4, and the cylindrical groove 303 is coaxially arranged with the core groove 302; the cylindrical groove 303 can increase the error tolerance rate when the fiber ferrule 6 is inserted into the core 52 and prevent the core 52 from not being straightened at the end and unable to be inserted into the ferrule base 61.
[0036] In an embodiment of the present application, preferably, as Figure 7 、 Figure 9As shown, the fiber-passing sliding seat 3 includes a sliding seat base 31 and a sliding seat upper cover 32 that are hinged to each other. The sliding seat upper cover 32 can be separated from the sliding seat base 31 from the side. Correspondingly, the conical groove 301 and the cylindrical groove 303 are divided into upper and lower parts. The fiber core groove 302 is provided on the sliding seat base 31, and the upper end of the fiber core groove 302 is covered by the sliding seat upper cover 32. The fiber-passing sliding seat 3 is divided into two parts, which facilitates the removal of the optical fiber 5 and the optical fiber ferrule 6 after the fiber passing is completed. Since the fiber core groove 302 requires a smaller diameter (0.13mm - 0.2mm), in order to ensure the accuracy of the fiber core groove 302, the fiber core groove 302 is only provided on the sliding seat base 31, and the position corresponding to the fiber core groove 302 on the sliding seat upper cover 32 is a plane. The cross-section of the fiber core groove 302 is correspondingly set in the shape of a combination of a semicircle and a rectangle (as Figure 9 shown).
[0037] In an embodiment of the present application, preferably, as Figure 7 , Figure 8 shown, when the ferrule sliding seat 4 abuts against the fiber-passing sliding seat 3, there is a gap between the end face of the ferrule base 61 and the end face of the cylindrical groove 303 to prevent damage to the optical fiber ferrule 6 caused by extrusion. The specific solution can be as Figure 8 shown. The upper surface of the ferrule sliding seat 4 is provided with an avoidance groove 41, and the avoidance groove 41 makes one end of the ferrule base 61 facing the fiber-passing sliding seat 3 suspended. Therefore, on the one hand, a part of the ferrule base 61 can be smoothly inserted into the cylindrical groove 303, and on the other hand, since the ferrule sliding seat 4 abuts against the fiber-passing sliding seat 3 in advance, the ferrule base 61 will not abut against the fiber-passing sliding seat 3, avoiding damage to the optical fiber ferrule 6.
[0038] In an embodiment of the present application, preferably, the clamping base 2 is provided with a semi-cylindrical clamping groove 21, and the clamping groove 21 is coaxial with the conical groove 301. The clamping groove 21 plays a positioning role and can quickly place the coating layer of the optical fiber 5 on the clamping base 2.
[0039] In an embodiment of the present application, preferably, the clamping base 2 is provided with a convex block 22 that can be embedded in the conical groove 301 toward the fiber-passing sliding seat 3, and the cross-section of the coating layer 51 is parallel to the end of the convex block 22. In this way, after the ferrule insertion work is completed, the end face of the coating layer 51 can be as close as possible to the optical fiber ferrule 6, preventing the fiber core 5 from breaking due to being too long.
[0040] In an embodiment of the present application, preferably, a pressing plate 7 is hinged to the clamping base 2 and the ferrule sliding seat 4. The pressing plate 7 is used to fix the coating layer 51 and the optical fiber ferrule 6, and the pressing plate 7 can be separated from the clamping base 2 and the ferrule sliding seat 4 from the side.
[0041] In an embodiment of the present application, preferably, a sliding seat groove 11 is provided on the upper surface of the base 1, a sliding rod groove 12 is arranged in the sliding seat groove 11, a sliding rod 13 is provided in the sliding rod groove 12, and sliders capable of passing through the sliding rod 13 are provided at the bottom ends of the fiber-passing sliding seat 3 and the ferrule sliding seat 4. The sliders slide in the sliding rod groove 12, a spring 14 is sleeved on the sliding rod 13, and two ends of the spring 14 respectively abut against the slider and the inner wall of the base 1, wherein the inner wall of the base 1 is the side wall on the lower side of the clamping base 2; double sliders can be provided at the bottom ends of the fiber-passing sliding seat 3 and the ferrule sliding seat 4 to ensure the accuracy of the sliding direction, and corresponding numbers of sliding rod grooves 12, sliding rods 13 and springs 14 are also provided.
[0042] In an embodiment of the present application, preferably, the length of the sliding rod groove 12 where the slider of the fiber-passing sliding seat 3 is located is less than the length of the sliding rod groove 12 where the slider of the ferrule sliding seat 4 is located. Therefore, when no external force is applied, the fiber-passing sliding seat 3 is located between the clamping base 2 and the ferrule sliding seat 4.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
