Description

Technical Field

[0001] This utility model relates to the field of fiber optic access and branching device installation technology, specifically a fiber coil assembly suitable for fiber optic branching or splitter box internal fiber organization and storage. Background Technology

[0002] During the assembly of fiber optic splitters, the trunk fiber and numerous other fibers need to be arranged, coiled, and combined in an orderly manner. While some existing fiber coiling assemblies on the market (refer to patents CN 222070908U and CN 220584461U) have achieved fiber coiling to some extent, they still have several major problems that urgently need to be addressed:

[0003] 1. In terms of structure, existing fiber optic assemblies often assemble internal optical fibers by connecting multiple components in series, resulting in a complex assembly process and high cost. This complex design not only increases production costs but also restricts production efficiency. Secondly, existing assemblies are relatively large in size. Although they provide enough space to arrange optical fibers, they are not suitable for internal packaging in space-constrained splitters. The excessive size not only increases the overall size of the product but may also affect the compactness and aesthetics of the splitter.

[0004] 2. In the process of fiber optic cable arrangement, the lack of an effective optimization and uniform distribution mechanism in existing components can easily lead to uneven arrangement and an increase in jamming points, which increases the risk of fiber core bending and stress concentration, and thus directly affects the normal service life of the fiber.

[0005] In view of the above problems, there is an urgent need for a new type of fiber optic coil assembly that can significantly improve device packaging accuracy and assembly efficiency. This assembly should be compact and highly integrated, and capable of efficient and precise automated installation to meet the high standards required in modern fiber optic splitter assembly processes. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a fiber coiling assembly for the winding and arrangement of optical fibers inside a splitter, which solves the problems of complex structure, large space occupation, and lack of buffering function of existing fiber coiling assemblies.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides an optical fiber disc assembly for a splitter, including an annular disc and a bracket. The bracket is fixedly connected to the splitter housing, and the annular disc is fixed on the bracket. The annular disc has a central hole and a wire groove circumferentially formed along the central hole. The central hole communicates with the wire groove. Each wire groove is provided with a winding part, and a buffer part is provided on the winding part.

[0009] According to one embodiment of the present invention, the diameter of the central hole is 15 to 40 mm, and the width of the conductor groove is slightly wider than the diameter of the optical fiber sheath.

[0010] According to one embodiment of the present invention, the annular disk is divided into a partition block and a partition ring by a wire groove. The inner ring of the partition ring is connected to the partition block. The winding part is a winding block disposed between two adjacent partition blocks. The winding block and the partition ring are integral structures. The buffer part is a rounded corner disposed on the winding block and the partition ring and a part that smoothly transitions between the two.

[0011] According to one embodiment of the present invention, a notch is provided at the inner end of two adjacent separating blocks, and the notch is inverted conical in shape to allow optical fibers to pass through.

[0012] According to one embodiment of the present invention, the annular disk is formed by splicing two identical semi-circular disk bodies. Each of the splicing end faces of the disk bodies is provided with a protrusion and a groove. The protrusion on one disk body is inserted into the groove on the other disk body. The outer end face of the protrusion is magnetized as the S pole, and the inner end face of the groove is magnetized as the N pole.

[0013] According to one embodiment of the present invention, the bracket is a cover structure, the bottom of the bracket is connected to a foot plate, a plurality of clearance grooves are provided on the circumferential end face of the bracket, a support piece is provided between each pair of clearance grooves, the support piece is set to avoid the wire groove, a guide cylinder for inserting into the center hole is fixedly connected to the inner end face of the bracket, a screw cap is threaded to the bottom end of the guide cylinder, and the bottom end face of the annular disk abuts against the screw cap.

[0014] According to one embodiment of the present invention, a plug adapted to the wire groove is connected to the outer end face of the guide cylinder.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] The orderly guidance and convergence of optical fibers are achieved through the central hole of the annular disk and the circumferential conductor groove. The winding section provides a winding support point for the optical fiber, which facilitates orderly winding. The buffer section can alleviate the bending stress during optical fiber winding and reduce the risk of damage. The bracket and the splitter box are fixed to ensure the overall installation of the assembly is stable. The overall structure makes the optical fiber winding orderly, avoids messy tangling, and improves the protection effect of optical fiber and space utilization.

[0017] The two semi-circular disks are connected to facilitate the placement, removal, and maintenance of optical fibers. They can be operated without disassembling the whole structure, improving convenience. The interlocking of the protrusions and grooves, as well as the magnetic attraction between the S and N poles, ensure that the structure is stable and not easy to loosen after splicing. At the same time, it can be quickly disassembled and assembled, balancing stability and operability. Attached Figure Description

[0024] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] like Figure 1 and Figure 2 As shown in Embodiment 1 of this utility model, an optical fiber coiling assembly for a splitter includes an annular disc 1 and a support 2. The support 2 is fixedly connected to the splitter housing, and the annular disc 1 is fixed on the support 2. That is, the annular disc 1 is mounted on the splitter housing through the support 2. The annular disc 1 has a central hole 101 and a guide groove 102 circumferentially formed along the central hole 101. The central hole 101 communicates with the guide groove 102. A main optical cable is stripped into multiple optical fibers, and then the main optical cable is passed through the central hole 101. These optical fibers on the main optical cable are then passed through the guide groove 102. Each guide groove 102 is provided with a winding part, through which the optical fiber is coiled. In addition, a buffer part is provided on the winding part to disperse the bending radius of the optical fiber and reduce stress concentration.

[0026] The central hole 101 is used for the introduction of the main optical cable. Its diameter depends on the number of main optical cable bundles. In this embodiment, the diameter of the optical fiber sheath is between 0.3 and 0.6 mm. Therefore, the diameter of the central hole 101 can be set to 15 to 40 mm. Furthermore, the width of the conductor groove 102 is slightly wider than the diameter of the optical fiber sheath.

[0027] refer to Figure 2 The number of wire grooves 102 is 16, and the number of wire grooves 102 is an even number. In this embodiment, the number of wire grooves 102 ranges from 16 to 48. The annular disk 1 is divided into partition blocks 103 and partition rings 105 by the wire grooves 102. The inner ring of the partition ring 105 is connected to the partition block 103. The winding part is a winding block 104 disposed between two adjacent partition blocks 103. The winding block 104 and the partition ring 105 are an integral structure. The buffer part is the rounded corners disposed on the winding block 104 and the partition ring 105 to smoothly transition between them. In this part, the inner and outer sides of the winding block 104 are provided with different curvatures. The curvature of the inner side of the winding block 104 is the rounded corner part provided on the upper and lower sides of the winding block 104 facing the central hole 101, and the curvature of the outer side of the winding block 104 is the rounded corner part provided on the upper and lower sides of the winding block 104 away from the central hole 101. The curvature of the outer side of the winding block 104 is greater than that of the inner side. In this way, the winding block 104 winds the optical fiber in an orderly manner one or more times along the conductor groove 102. The buffer part avoids the optical fiber having the same bending radius after winding, reducing stress concentration.

[0028] refer to Figure 2 The number of wire grooves 102 is 16, and the number of wire grooves 102 is an even number. In this embodiment, the number of wire grooves 102 ranges from 16 to 48. The annular disk 1 is divided into partition blocks 103 and partition rings 105 by the wire grooves 102. The inner ring of the partition ring 105 is connected to the partition block 103. The winding part is a winding block 104 disposed between two adjacent partition blocks 103. The winding block 104 and the partition ring 105 are an integral structure. The buffer part is the rounded corners disposed on the winding block 104 and the partition ring 105 to smoothly transition between them. In this part, the inner and outer sides of the winding block 104 are provided with different curvatures. The curvature of the inner side of the winding block 104 is the rounded corner part provided on the upper and lower sides of the winding block 104 facing the central hole 101, and the curvature of the outer side of the winding block 104 is the rounded corner part provided on the upper and lower sides of the winding block 104 away from the central hole 101. The curvature of the outer side of the winding block 104 is greater than that of the inner side. In this way, the winding block 104 winds the optical fiber in an orderly manner one or more times along the conductor groove 102. The buffer part avoids the optical fiber having the same bending radius after winding, reducing stress concentration.

[0029] Furthermore, in this embodiment, a notch 1031 can be opened between the inner ends of two adjacent separating blocks 103. The notch 1031 is in the shape of an inverted cone to facilitate the insertion of optical fibers.

[0030] like Figure 3 As shown, the bracket 2 is a cover structure. The bottom of the bracket 2 is connected to a foot plate 201. Multiple clearance grooves 202 are opened on the circumferential end face of the bracket 2. Between each pair of clearance grooves 202 is a support piece 203. The support piece 203 is set to avoid the wire groove 102. A guide cylinder 204 for inserting into the center hole 101 is fixedly connected to the inner end face of the bracket 2. The bottom end of the guide cylinder 204 is threadedly connected to a cap 205. The bottom end face of the annular disk 1 abuts against the cap 205. Example 2

[0031] like Figure 5 As shown, this is a fiber optic disc assembly for a splitter provided in Embodiment 2 of the present invention. The difference from Embodiment 1 is that the annular disc 1 in this embodiment adopts a split structure. The annular disc 1 is composed of two identical semi-circular disc bodies 1000 spliced ​​together. Each of the splicing end faces of the disc bodies 1000 is provided with a protrusion 1001 and a groove 1002. The protrusion 1001 on one disc body 1000 is inserted into the groove 1002 on the other disc body 1000. The outer end face of the protrusion 1001 is magnetized as the S pole, and the inner end face of the groove 1002 is magnetized as the N pole. When the two disc bodies 1000 are connected, the positioning and insertion are completed through their respective protrusions 1001 and grooves 1002. Then, the outer end face of the protrusion 1001 and the inner end face of the groove 1002 are attracted to each other to form a fixed connection between the two disc bodies 1000.

[0032] In this embodiment, the two disks 1000 have the same number of wire grooves 102. During use, firstly, the two identical semi-circular disks 1000 of the split-type annular disk 1 are separated. During separation, a pulling force is applied along the splicing end face to overcome the magnetic force and separate the two, resulting in two independent semi-circular disks 1000. Subsequently, fiber optic winding is performed on the separated disks 1000: the fiber optic cable of the splitter is introduced from the starting end of a single disk 1000 and wound along its semi-circular surface along the wire grooves 102 onto the winding block 104. During the process, the fiber optic cable must be kept neatly arranged and avoid crossing, knotting, or excessive bending, so that the fiber optic cable is tightly attached to the disk 1000 to form an orderly annular coil. The two disks 1000 can be wound independently, sequentially or simultaneously, without interfering with each other.

[0033] After winding, the discs are spliced ​​together. The protrusion 1001 on the splicing end face of one disc 1000 is aligned with the groove 1002 on the end face of another disc 1000, and axially pushed to achieve insertion and positioning. At this time, the outer end face (S pole) of the protrusion 1001 and the inner end face (N pole) of the groove 1002 automatically lock together due to the attraction of opposite poles, forming a seamless and fixed complete annular disc 1, requiring no additional fasteners. The split structure avoids the space limitations of the complete annular disc 1 through independent winding, making operation more convenient, while the magnetic design ensures splicing efficiency and connection reliability. The annular disc 1 can then be installed on the bracket 2 as described in Example 1. Example 3

[0034] like Figure 5 As shown, this is a fiber optic disc assembly for a splitter provided in Embodiment 3 of the present invention. Based on Embodiment 1 or Embodiment 2, a plug 2041 adapted to the wire groove 102 is connected to the outer end face of the guide cylinder 204. When installing the annular disc 1, the plug 2041 is inserted into the wire groove 102 so that the annular disc 1 is positioned on the bracket 2.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
