[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment one:

[0037] like Figure 1-9As shown, a 45° optical fiber array for high-speed data transmission includes an input optical fiber 1, an output optical fiber 2 and an optical fiber connector 4. The cross-section of the top surface of the optical fiber connector 4 is an isosceles right triangle. A connecting joint 7 or a connecting groove 8 is provided on the surface of the optical fiber connector 4 away from the right angle side. The optical fiber connector 4 is provided with multiple groups. The size, shape and internal structure of adjacent optical fiber connectors 4 are the same. The connecting joints 7 and the connecting groove 8 of adjacent optical fiber connectors 4 are clearance-matched. The side lengths of the optical fiber connector 3 and the optical fiber connector 4 that abut against each other coincide, and the angle of one end of the optical fiber connector 3 and the optical fiber connector 4 that abut against each other is 45 degrees. The contours of the connecting joint 7 and the connecting groove 8 are the same as the contour of the transmission joint 5. The connecting joint 7 is located at the center of the oblique side of the optical fiber connector 4. The outer edges of the optical fiber connector 4 are all rounded, and the outer edges of the optical fiber connector 3 are all rounded. The entire optical fiber connector 4 adopts an isosceles right triangle structure, so that the two ends are at an angle of 45 degrees, so that the adjacent optical fiber connectors 4 present a regular right-angle structure when the ends are assembled. The entire volume structure is small, and the volume is regular after multiple splicing, with high space utilization. Adjacent optical fiber connectors 4 are assembled by directly inserting connecting joints 7 and connecting grooves 8. Two optical fiber connectors 4 are directly plugged in through the bevel edges, and a group of square structures are formed after splicing. Two transmission grooves 6 are provided on the surface as input ends, and two transmission connectors 5 are provided as output ends, which can realize two-in and two-out transmission, or one-in and two-out, two-in and one-out transmission structure. Similarly, multiple optical fiber connectors 4 can be assembled according to actual use needs. Through the clearance fit between the connecting joints 7 and the connecting grooves 8, multiple optical fiber connectors 4 can be assembled into a larger scale or a specific shape of optical fiber array. The modular design makes the expansion and customization of the optical fiber array simple and fast, meeting the needs of different application scenarios. The assembly process does not require complicated tools or techniques, which reduces the threshold for installation and maintenance. The clearance fit between the optical fiber connectors 4 ensures the stability and reliability of the assembly, and reduces the transmission problems caused by poor connection.

[0038] When the optical fiber is connected inside the optical fiber connector 4 for transmission, the input optical fiber 1 and the output optical fiber 2 are respectively connected to the two sides of the optical fiber connector 4, a transmission cavity 9 is provided inside the optical fiber connector 4, and a plurality of optical fiber transmission plates 10 are provided inside the transmission cavity 9. The optical signal is transmitted inside the optical fiber connector 4 through the plurality of optical fiber transmission plates 10, and an adjustment sleeve 11 is provided at one end of the optical fiber transmission plate 10. A polygonal shaft groove 12 is provided at the center of the adjustment sleeve 11. The adjustment sleeves 11 at the ends of adjacent optical fiber transmission plates 10 are vertically staggered. A polygonal shaft body 13 is penetrated on the surface of the polygonal shaft groove 12, and the top of the polygonal shaft body 13 penetrates the surface of the optical fiber connector 4. The adjacent optical fiber transmission plates 10 are distributed along the circumference of the transmission cavity 9. The adjustment sleeves 11 at the ends of the optical fiber transmission plates 10 are vertically staggered. The central axis lines coincide with each other, and a plurality of adjusting sleeves 11 are provided, each of which is connected to an optical fiber transmission plate 10. To ensure that the adjusting sleeves 11 do not slide when connected vertically, a guide ring groove 15 is provided on one end surface of the adjusting sleeve 11, and the guide ring groove 15 is a blind groove. A guide ring body 14 is provided on the other end surface of the adjusting sleeve 11, and the guide ring body 14 is movably located inside the guide ring groove 15. Through the engagement between the guide ring groove 15 and the guide ring body 14, a plurality of adjusting sleeves 11 are vertically limited to prevent horizontal sliding, and adjacent adjusting sleeves 11 are guaranteed to rotate along the central axis when stacked vertically, so as to facilitate the adjustment of the optical fiber transmission plate 10. When adjusting the angle of the optical fiber transmission plate 10, according to the connection position of the optical fiber transmission plate 10, such as Figure 3 As shown, the adjustment sleeves 11 are set from top to bottom and named A, B, and C, and the optical fiber transmission plates 10 connected to the surface are a, b, and c from right to left. When the position A needs to be adjusted, the polygonal shaft body 13 is vertically inserted along the penetration position of the top surface of the optical fiber connector 4 until it is against the surface of the adjustment sleeve 11 at the A position. Since the polygonal shaft groove 12 inside the adjustment sleeve 11 is engaged with the polygonal shaft body 13, the rotation of the polygonal shaft body 13 can drive the adjustment sleeve 11 at the A position to rotate, thereby driving the optical fiber transmission plate 10 at the a position to adjust the angle. When the angle B is adjusted, The angles of the adjusting sleeves 11 at the A, B, and C positions remain unchanged. After the adjustment is completed, the adjusting sleeves 11 can be vertically inserted into the adjusting sleeves 11 at the A, B, and C positions. The design of the adjustable optical fiber transmission plate 10 allows the optical signal to be guided in different directions, thereby improving the flexibility and adaptability of the transmission. The transmission method of the polygonal axis main body 13 and the polygonal axis groove 12 ensures the accuracy and stability of the adjustment. The angle and position adjustment of the optical fiber transmission plate 10 can be adjusted according to actual needs, thereby optimizing the transmission path of the optical signal and reducing the loss during the transmission process.

[0039] To facilitate the access of the optical fiber connector 4 to the input optical fiber 1 and the output optical fiber 2, a transmission joint 5 and a transmission groove 6 are respectively provided at the right-angled sides adjacent to the optical fiber connector 4, and an optical fiber connector 3 is provided at the ends of the input optical fiber 1 and the output optical fiber 2. The surface of the optical fiber connector 3 of the input optical fiber 1 is provided with an input joint 16, and the surface of the optical fiber connector of the output optical fiber 2 is provided with an output groove 17. The input joint 16 and the transmission groove 6 on the surface of the optical fiber connector 4 are gap-fitted, and the output groove 17 and the transmission joint 5 on the surface of the optical fiber connector 4 are gap-fitted. The input optical fiber 1 and the output optical fiber 2 are both connected to the optical fiber connector 4 through the optical fiber connector 3. Compared with the traditional line connection access method, the design of the optical fiber connector 3 simplifies the optical fiber connection process and improves the convenience of installation. The gap-fit ​​design enhances the stability and reliability of the connection and reduces the transmission problems caused by loose connections.

[0040] Other limiting structures of the entire device are that the input connector 16, output groove 17, transmission connector 5 and transmission groove 6 have the same contour and size, and the surface contour of the input connector 16 is a centrally symmetrical structure, so that the entire input connector 16, output groove 17, transmission connector 5 and transmission groove 6 are the same size. When connecting, there is no need to distinguish between up, down, left and right, and the optical fiber connector 4 can be directly inserted, which simplifies the connection process. There is no need to frequently determine the front and back sides when connecting. Through a unified interface, the optical fiber connector 4 and the optical fiber connector 3 are quickly connected, and the access angle of the optical fiber connector 3 can be adjusted according to actual use requirements. It is easy to install and has high adaptability. Specific embodiment 2:

[0042] like Figure 1-9 As shown, according to the content of specific embodiment 1, the following technical solutions are further disclosed:

[0043] Since the adjusting sleeve 11 is distributed vertically, its position is mainly moved by the engagement of the polygonal shaft body 13, so that when the angle of the adjusting sleeve 11 at the bottom is adjusted, it will have a linkage effect on the adjusting sleeve 11 at the top. Therefore, when adjusting, it is selected to first adjust the angle of the adjusting sleeve 11 at the bottom, that is, the adjusting sleeve 11 at position C, then adjust the angle of position B, and finally adjust position A.

[0044] In actual use, in order to facilitate the angular rotation adjustment between adjacent adjusting sleeves 11, the connected guide ring body 14 can be replaced with a bearing structure to reduce the friction between adjacent adjusting sleeves 11 and avoid linked rotation.

[0045] The optical fiber array of the present invention has broad application prospects and can be applied to multiple fields such as data centers, communication systems, optical fiber sensing, etc., and promotes the development of high-speed data transmission technology. Specific embodiment three:

[0047] like Figure 1-9 As shown, according to the content of the specific embodiment 1, the following technical contents are further disclosed:

[0048] The connections between the various interfaces and grooves of the entire optical fiber connector 4 ensure the normal output of the optical fiber signal.

[0049] The optical fiber transmission board 10 is usually made of a high-transmittance, low-loss material to ensure the efficiency and stability of the optical signal during transmission. The transmission path and mode of the optical signal must be considered during the actual design of the optical fiber transmission board 10 to ensure that the optical signal can be transmitted along a predetermined direction. The surface of the optical fiber transmission board 10 needs to be specially processed, such as coating or polishing, to reduce the scattering and reflection loss of the optical signal.

[0050] Working principle of optical fiber transmission board 10:

[0051] Input of optical signal: The optical signal enters the optical fiber connector 4 through the optical fiber connector 3 of the input optical fiber 1 and is transmitted to the transmission cavity 9. The optical fiber connector 3 of the input optical fiber 1 and the transmission groove 6 of the optical fiber connector 4 are gap-matched to ensure the stable input of the optical signal;

[0052] Optical signal transmission: The optical signal is transmitted on the optical fiber transmission board 10. The internal structure and material properties of the optical fiber transmission board 10 enable efficient and stable transmission of the optical signal. The design of the optical fiber transmission board 10 enables the optical signal to be transmitted along a predetermined path while reducing scattering and reflection losses.

[0053] Angle and position adjustment: When it is necessary to change the transmission direction of the optical signal or optimize the transmission path, the adjustment sleeve 11 and the optical fiber transmission plate 10 can be driven to rotate by rotating the polygonal shaft body 13. The matching design of the adjustment sleeve 11 and the polygonal shaft body 13 ensures the accuracy and stability of the rotation, thereby realizing precise adjustment of the angle and position of the optical fiber transmission plate 10.

[0054] Optical signal output: The optical signal transmitted through the optical fiber transmission board 10 is output through the optical fiber connector 3 of the output optical fiber 2, completing the entire transmission process. The optical fiber connector 3 of the output optical fiber 2 and the transmission connector 5 of the optical fiber connector 4 are gap-matched to ensure the stable output of the optical signal.

[0055] In the optical fiber transmission board 10, the transmission of optical fiber signals is mainly based on the principle of total reflection of light. The optical fiber is composed of a central high-refractive-index glass core and a surrounding low-refractive-index glass envelope, similar to a slender glass tube. When the optical signal enters the glass envelope with a lower refractive index from the glass core with a higher refractive index, if the incident angle is greater than a certain critical angle, total reflection of light will occur, and the optical signal will be confined to propagate in the glass core. The optical fiber transmission board 10, through its internal structure and material properties, enables the optical signal to maintain a total reflection state in the optical fiber and be transmitted to the destination along a predetermined path. At the same time, in order to maintain the intensity and stability of the optical signal, the optical fiber transmission board 10 may also need to cooperate with optical amplifiers, repeaters and other equipment to amplify and shape the optical signal. Specific embodiment four:

[0057] like Figure 1-9 As shown, according to the contents in the above specific embodiments, the following technical contents are further disclosed:

[0058] Accessing the optical signal with respect to the transmission connector 5, the transmission groove 6, the input connector 16 and the output groove 17 further includes the following contents;

[0059] Functions of the transmission connector 5 and the transmission groove 6: The transmission connector 5 and the transmission groove 6 are usually located at adjacent right-angled edges of the optical fiber connector 4. Their main function is to provide precise docking between optical fibers to ensure that the optical signal can be stably transmitted from one optical fiber to another.

[0060] The transmission connector 5 is usually designed to be a protruding shape, and its contour and size match the transmission groove 6 of the optical fiber connector 4. When two optical fiber connectors 4 need to be docked, the transmission connector 5 of one connector will be inserted into the transmission groove 6 of the other connector to form a tight clearance fit.

[0061] The transmission groove 6 is designed as a concave shape for receiving the transmission connector 5 from another connector. The contour and size of the groove match the transmission connector 5 to ensure the accuracy and stability of the docking.

[0062] When the transmission connector 5 is inserted into the transmission groove 6, the optical fiber end faces are in close contact, forming a transmission channel for the optical signal. The optical signal is transmitted through the core of the optical fiber and continues to be transmitted along the core of the next optical fiber at the contact point.

[0063] Functions of the input connector 16 and the output groove 17: The input connector 16 and the output groove 17 are located at the input and output ends of the optical fiber connector 4, and are used to receive external optical signals and output internal optical signals to external devices, respectively.

[0064] The input connector 16 is generally designed to be convex and is located at the input end of the optical fiber connector 4. Its surface profile may be similar to the transmission groove 6, but the specific shape and size may vary according to actual application requirements. The input connector 16 is used to receive optical signals from an external optical fiber or light source.

[0065] The output groove 17 is designed to be concave and located at the output end of the optical fiber connector 4. Its contour and size match the input connector 16 or are designed according to actual application requirements to receive the optical signal from the optical fiber transmission board 10 and output it to an external device.

[0066] When the optical signal of the external optical fiber or light source is transmitted to the input end of the optical fiber connector 4, the optical signal will enter the input connector 16 and be transmitted to the optical fiber transmission board 10 for further processing and transmission. The optical signal processed by the optical fiber transmission board 10 will be transmitted to the output groove 17 and output to the external device or the next optical fiber connector 4 through the output groove 17. At the output groove 17, the optical signal will leave the optical fiber connector 4 and continue to be transmitted along the predetermined transmission path. Specific embodiment five:

[0068] like Figure 1-9 As shown, according to the contents in the above specific embodiments, the following technical contents are further disclosed:

[0069] The optical fiber connector 4 can be assembled according to the actual use requirements, and the access direction of the optical fiber connection 3 of the input optical fiber 1 and the output optical fiber 2 can be adjusted according to the actual use requirements, such as Figure 7 As shown, two groups of optical fiber connectors 4 are selected to be assembled through the connecting joints 7 and the connecting grooves 8, as shown in FIG. Figure 8 As shown, two groups of optical fiber connectors 4 are selected to be assembled through the transmission connectors 5 and the transmission grooves 6 on the side, as shown in FIG. Fig. 9 As shown, three groups of optical fiber connectors 4 are selected for staggered assembly along the right angle edges, such as Figure 1 As shown, multiple groups of optical fiber connectors 4 are selected for regular stacking and assembly in the left, right, top and bottom directions, and connected and assembled according to actual usage requirements.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
