Description

Technical Field

[0001] This utility model relates to the field of fiber winding device technology, and in particular to an optical fiber disk and optical module. Background Technology

[0002] In recent years, with the rapid development of Internet technology, the demand for communication has continued to grow. The application of optical communication technology is becoming more and more widespread, and the requirements for optical modules are also getting higher and higher. This is reflected in the increasing degree of internal integration of products, which in turn leads to the need to make full use of the internal space of the products.

[0003] In optical modules, machined or sheet metal parts are typically used as fiber optic trays. Machined or sheet metal fiber optic trays with an inherent thickness exceeding 1mm will encroach on the space within the optical module, reducing the fiber winding area. Furthermore, if these fiber optic trays are not properly machined, there is a risk of scratching the fiber, leading to optical module failure. Additionally, due to the conductivity of metal fiber optic trays, their application on PCBs requires additional insulation protection, complicating their use. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide an optical fiber disk and a communication device to solve the problems in the prior art where the optical fiber disk has a small winding area, there is a risk of scratching the optical fiber, which leads to the failure of the optical module, and the metal optical fiber disk requires additional insulation protection on the PCB board due to its conductivity, making the application complicated.

[0005] This utility model discloses an optical fiber tray, comprising: a base plate and multiple fiber winding plates; the multiple fiber winding plates are distributed on the outer periphery of the base plate and located on one side of the base plate, and the multiple fiber winding plates and the base plate enclose a fiber winding area; wherein, the thickness of the base plate and the fiber winding plates is less than 1 mm, and the base plate and the fiber winding plates are made of film material.

[0006] Optionally, the fiber-wound board includes a first board and a second board connected in sequence to each other, the first board being connected to the base plate, and the first board, the second board, and the base plate enclosing the fiber-wound area.

[0007] Optionally, the first plate and the second plate are arranged perpendicular to each other.

[0008] Optionally, the base plate has a rectangular structure, and four fiber-wound boards are evenly distributed around the base plate; two opposing second boards are connected by abutment strips.

[0009] Optionally, the blocking strip is an adhesive tape.

[0010] Optionally, the fiber optic tray further includes multiple supports, the number of which is the same as the number of the fiber winding boards and is connected to the fiber winding boards one by one, and the supports are respectively disposed on the side of the first plate away from the fiber winding area.

[0011] Optionally, the bracket includes a first frame and a second frame connected in sequence, with the first frame and the second frame being perpendicular to each other. The first frame is connected to the first board, and the second frame is used to be mounted on the PCB board.

[0012] Optionally, the film material can be any one of HDPE, PC, or PI.

[0013] This utility model also discloses an optical module, including a housing, a PCB board and the aforementioned optical fiber disk, wherein the PCB board and the optical fiber disk are both disposed in the housing, and the base plate is disposed on the PCB board.

[0014] Optionally, the base plate is bonded to the PCB board.

[0015] Compared with the prior art, the beneficial effects of the fiber optic disk and optical module provided in this utility model embodiment are as follows: the base plate serves as the basic load-bearing component of the entire fiber optic disk, and multiple fiber winding plates are distributed on one side of the base plate. The two are combined to form a fiber winding area, which is used to wind the optical fiber. This application can control the thickness of the base plate and the fiber winding plates to be less than 1mm by limiting their materials, thereby reducing the overall thickness of the fiber optic disk. Within the limited application space inside the optical module, the fiber winding space gains more usable space in the vertical direction.

The increased fiber area allows for the winding of longer optical fibers, enhancing the performance of the optical module. Furthermore, the base plate and the winding board of this application are made of a film material. This film material is relatively soft and has a smoother, flatter surface, effectively reducing the risk of scratching the optical fiber during use. The film material itself is non-conductive and is an insulating material, eliminating the need for special insulation treatment when combined with the PCB board. This simplifies the installation and use of the fiber optic coil in the optical module and reduces the risk of electrical faults caused by improper insulation, making the design and manufacturing of the optical module more convenient and efficient.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] This utility model embodiment provides an optical fiber disk 100, such as Figures 1 to 2 As shown, there is a base plate 10 and a plurality of fiber-wound boards 20. The plurality of fiber-wound boards 20 are distributed on the outer periphery of the base plate 10 and located on one side of the base plate 10. The plurality of fiber-wound boards 20 and the base plate 10 enclose a fiber-wound area 101. The thickness of the base plate 10 and the fiber-wound boards 20 is less than 1 mm. The base plate 10 and the fiber-wound boards 20 are made of film material.

[0023] The base plate 10 serves as the fundamental supporting component of the entire fiber optic disk 100. Multiple fiber winding plates 20 are distributed on one side of the base plate 10, and the two together enclose a winding area 101 for winding optical fibers. This application reduces the overall thickness of the fiber optic disk 100 by limiting the thickness of the base plate 10 and the fiber winding plates 20 to less than 1 mm. Within the limited application space inside the optical module, the winding space 101 gains more usable space in the vertical direction. Therefore, without increasing the overall size of the optical module, increasing the winding area allows for winding of longer fiber lengths. The optical fiber enhances the performance of the optical module. Furthermore, the base plate 10 and the fiber winding board 20 of this application are made of film material. The film material itself is relatively soft and has a smoother, flatter surface, effectively reducing the risk of scratching the optical fiber during use. Moreover, the film material itself is non-conductive and is an insulating material, eliminating the need for special insulation treatment when combined with the PCB board 60. This simplifies the installation and use of the optical fiber tray 100 in the optical module and reduces the risk of electrical faults caused by improper insulation treatment, making the design and manufacturing of the optical module more convenient and efficient.

[0024] As a preferred embodiment, refer to Figure 1 The fiber-wound board 20 includes a first board 210 and a second board 220 connected in sequence. The first board 210 is connected to the base plate 10. The first board 210, the second board 220 and the base plate 10 enclose a fiber-wound area 101.

[0025] The fiber winding board 20 is composed of a first plate 210 and a second plate 220, making the structure of the winding region 101 more regular and reasonable. The first plate 210 is connected to the base plate 10, providing a stable foundation connection for the winding region 101 and ensuring the connection strength between the fiber winding board 20 and the base plate 10. The second plate 220 further expands and defines the boundary of the winding region 101 based on the first plate 210. This structural design can better guide the optical fiber to coil within the winding region 101, making the coiling of the optical fiber more orderly and avoiding the tangled situation of the optical fiber. In actual optical fiber coiling, the operator can more clearly operate according to the spatial boundary formed by the first plate 210 and the second plate 220, improving coiling efficiency and quality.

[0026] As a preferred embodiment, refer to Figure 1 The first plate 210 and the second plate 220 are arranged perpendicular to each other.

[0027] The first plate 210 and the second plate 220 are arranged vertically to ensure sufficient fiber winding area 101 while providing stable support for the optical fiber in the vertical direction, preventing the optical fiber from detaching from the optical fiber disk 100 and ensuring the stability of optical signal transmission.

[0028] As a preferred embodiment, refer to Figure 1 The base plate 10 has a rectangular structure, and four fiberboards 20 are evenly distributed around the base plate 10. Two opposing second plates 220 are connected by a retaining strip 30.

[0029] The four fiber-wound boards 20 are evenly distributed around the rectangular base plate 10, giving the fiber-wound area 101 a high degree of symmetry. This symmetrical structure has better mechanical balance performance, ensuring stable transmission of optical fiber signals.

[0030] In this embodiment, refer to Figure 1 The four corners of the base plate 10 are rounded.

[0031] After the fiber is wound, the retaining strip 30 can close the winding area 101 to prevent the fiber from popping out of the fiber optic disc 100 and ensure that the fiber is always kept on the predetermined winding path. This is crucial for ensuring the neat arrangement and stable transmission of the fiber. Especially when the optical module needs to be moved frequently or subjected to vibration, the retaining strip 30 can effectively avoid fiber tangling, reduce signal transmission failures caused by changes in fiber position, and improve the performance of the optical module.

[0032] As a preferred embodiment, the blocking strip 30 is an adhesive tape.

[0033] The adhesive tape possesses excellent adhesion. After fiber winding, it is quickly and easily applied to the two opposing second plates 220, a simple and convenient operation requiring no complex tools or processes. Furthermore, if the tape's position or length is found to be incorrect during installation, it can be easily peeled off and re-applied for adjustment. Simultaneously, the tape is soft and flexible, allowing it to adhere tightly to the surfaces of the second plates 220 and the optical fiber without causing hard compression or scratches, thus ensuring the performance of the optical module.

[0034] As a preferred embodiment, refer to Figure 2 The fiber optic tray 100 also includes multiple supports 40. The number of supports 40 is the same as the number of fiber winding boards 20 and they are connected to the fiber winding boards 20 one by one. The supports 40 are respectively located on the side of the first plate 210 away from the fiber winding area 101.

[0035] The bracket 40 is connected to the fiber winding board 20 in a one-to-one correspondence and is set on the side of the first plate 210 away from the fiber winding space. It can provide multiple support points for the fiber optic tray 100, improve the setting stability of the fiber optic tray 100, prevent the fiber optic tray 100 from being deformed by external forces such as the tension of the fiber optic cable and the pressure during the installation process, provide a stable setting environment for the fiber optic cable, ensure the stable transmission of the fiber optic signal, and thus improve the performance of the optical module.

[0036] As a preferred embodiment, refer to Figure 2 The bracket 40 includes a first frame 410 and a second frame 420 connected in sequence, and the first frame 410 and the second frame 420 are perpendicular to each other. The first frame 410 is connected to the first board 210, and the second frame 420 is used to be mounted on the PCB board 60.

[0037] The first frame 410 and the second frame 420 are arranged vertically to form an L-shaped support structure 40. The support 40 can stabilize the fiber optic tray 100 on the PCB board 60, improve the application stability of the fiber optic tray 100, and thus ensure the performance of the fiber optic cable and signal transmission in the optical module.

[0038] In this embodiment, the first frame 410 and the second frame 420 can be connected to the first plate 210 and the PCB board 60 respectively by adhesive bonding, so as to ensure the ease of installation and stability of the bracket 40.

[0039] As a preferred embodiment, the film material can be any one of HDPE, PC, or PI.

[0040] In this embodiment, the film material is specified to be any one of HDPE (high-density polyethylene), PC (polycarbonate), or PI (polyimide). Using these materials as the film material effectively protects the optical fiber from scratches and other damage, while also providing good electrical insulation properties, making it suitable for optical modules with high operating temperature requirements or strict electrical performance requirements.

[0041] The materials used in this embodiment are inexpensive, the processing method is simple, the mold opening is simple, and the cost can be reduced.

[0042] This application also discloses an optical module, as shown in the embodiments below. Figure 1 and Figure 2 The optical module includes a housing 50, a PCB board 60, and the fiber optic tray 100 from the aforementioned embodiments. This optical module has the same structure and beneficial effects as the fiber optic tray 100 from the aforementioned embodiments. The structure and beneficial effects of the fiber optic tray 100 have been described in detail in the aforementioned embodiments and will not be repeated here.

[0043] The optical module, consisting of the fiber optic tray 100, the housing 50, and the PCB board 60, fully leverages the advantages of the fiber optic tray 100, such as saving space and increasing the fiber winding area, further enhancing the internal integration of the optical module. Located on the PCB board 60, it requires no additional insulation protection, making it convenient to use. It also protects the optical fiber from scratches, helping to maintain the stability and reliability of the optical signal transmission of the optical module and improving the overall performance of the optical module.

[0044] In this embodiment, refer to Figure 2 The PCB board 60 is located at the bottom of the housing 50 by fasteners 70, which can be screws.

[0045] As a preferred embodiment, the base plate 10 is bonded to the PCB board 60.

[0046] Adhesion is a common and effective connection method. By using a suitable adhesive, the base plate 10 of the fiber optic tray 100 is firmly fixed to the PCB board, achieving a stable connection between the two. During the operation of the optical module, even under external forces such as vibration and impact, the adhesive connection ensures that the fiber optic tray 100 will not easily shift or loosen. Compared with other connection methods (such as screw fixing), adhesive does not leave holes on the PCB board, avoiding the problems of reduced PCB board structural strength and damaged electrical performance that may be caused by drilling, thus ensuring the performance of the optical module.
