[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] like Figures 1 to 5 As shown, the embodiment of the present application provides a shaft unit, the shaft unit 2 includes a winding post 2-3 and a first stopper 2-1 and a second stopper 2-2 connected to the upper end and the lower end of the winding post 2-3. When in use, the optical cable 7 can be wound around the outer side of the winding post 2-3 to realize the optical cable storage function. The first stopper 2-1 and the second stopper 2-2 are respectively used to perform upper and lower stopper on the optical cable 7 wound on the winding post 2-3 to prevent the wound optical cable 7 from spreading from the upper and lower parts.

[0050] In order to realize the function of storing and pulling out the optical cable, the connector at one end of the optical cable 7 is generally fixed on the shaft unit 2. However, the position of the connector is basically fixed after the optical cable 7 is stored. In the prior art, the optical fiber panel only has one connector fixing position. Therefore, in order to match the fixing position of the connector, it is necessary to accurately control the length of the optical cable 7, which increases the production and assembly costs. The present application provides two or more fixing components 2-1-1 on the first limit member 2-1. When in use, the fixing component 2-1-1 at a suitable position can be selected according to the length of the optical cable 7, which greatly reduces the requirement on the length of the optical cable 7, thereby effectively reducing the production and assembly costs. At the same time, by providing two or more fixing components 2-1-1, the optical fiber panel can also be suitable for optical cables 7 with multiple connectors on a single end, thereby further improving the scope of application of the optical fiber panel. Considering that the more the number of fixing components 2-1-1, the lower the requirement on the length of the optical cable, but the excessive number of fixing components 2-1-1 will greatly increase the production cost and product size of the optical fiber panel, the number of fixing components is preferably 2 to 6.

[0051] Furthermore, the fixing components 2-1-1 are arranged adjacent to each other, thereby providing fixing positions for multiple connectors of the optical cable 7, making it easier to store and fix the optical cable with multiple connectors at a single end.

[0052] Considering that the adjacent arrangement of each fixing component 2-1-1 still has a relatively strict requirement on the length of the optical cable, the present application further optimizes the arrangement of the first limiter 2-1, and the first limiter 2-1 includes at least two groups of fixed modules arranged at intervals, and each group of fixed modules includes one fixing component 2-1-1 or at least two fixing components 2-1-1. For example, Figure 1 , 3 , 4 are embodiments in which each set of fixing modules includes a fixing component 2-1-1, Figure 5An embodiment in which each group of fixing modules includes two adjacent fixing components 2-1-1. The fixing modules arranged at intervals can provide a wider range of selection space for connector fixation, further reducing the requirements for the length of the optical cable, and the fixing modules arranged at intervals can also meet the requirements for the inventory fixation of optical cables with multiple connectors on a single end. At the same time, by arranging at least two adjacent or interval fixing components 2-1-1 in each group of fixing modules, for optical cables with multiple connectors on a single end, after the inventory is completed, the fixing module at a suitable position can be selected according to the length of the optical cable, and then each connector can be fixed in each fixing component of the fixing module in turn, which can not only meet the requirements for the inventory of optical cables with multiple connectors on a single end, but also effectively reduce the requirements for the length of the optical cable.

[0053] Furthermore, considering that there are many types of connectors, but the fiber optic panel in the prior art can usually only support one type of connector and has a relatively simple function, the winding post 2-3 preferably adopts a detachable split structure, and the winding post 2-3 specifically includes a first column 2-3-1 and a second column 2-3-2, the first column 2-3-1 is connected to the first limiter 2-1 along the circumferential direction, and the second column 2-3-2 is connected to the second limiter 2-2 along the circumferential direction. In actual applications, the first limiter 2-1 and the second limiter 2-2 can be disassembled by separating the first column 2-3-1 from the second column 2-3-2, and then the first limiter 2-1 with a suitable fixing component is selected according to the type of connector and assembled and connected, so that the fiber optic panel can support the installation of multiple connectors, thereby expanding the scope of application of the fiber optic panel and further reducing the production and assembly costs.

[0054] Preferably, the first column 2-3-1 and the second column 2-3-2 can be connected by snap-fit ​​connection or threaded connection. Figure 2 and Fig.10 It is a specific schematic diagram of the snap connection. The bottom end of the first column 2-3-1 is provided with a plurality of snaps 2-3-1-1 extending downward, and the top end of the second column 2-3-2 is correspondingly provided with a plurality of slots 2-3-2-1. The first column 2-3-1 and the second column 2-3-2 can be connected by embedding the snaps 2-3-1-1 into the slots 2-3-2-1.

[0055] Furthermore, the first limiter 2-1 and the second limiter 2-2 can be an integral annular structure. From the perspective of facilitating mold forming, the first limiter 2-1 and the second limiter 2-2 can also be respectively composed of at least two blades arranged at intervals. Preferably, the blades of the first limiter 2-1 and the blades of the second limiter 2-2 are staggered in the vertical direction, and each fixing module is arranged on each blade of the first limiter 2-1, and the number of fixing modules is less than or equal to the number of blades.

[0056] In a preferred embodiment of the present invention, the first stopper 2-1 has a sinking space of a certain depth, and the fixing assembly 2-1-1 is arranged in the sinking space, so that the connector fixed on the shaft unit is nearly flush with the first stopper 2-1 in height, thereby effectively reducing the volume of the optical fiber panel. At the same time, in order to guide the optical cable 7 to be released and arranged on the first stopper 2-1, and to prevent the optical cable 7 on the first stopper 2-1 from being higher than the height of the first stopper 2-1, a wire groove for passing the optical cable 7 or the connector is provided on the first stopper 2-1 and / or the winding pole 2-3. In practical applications, the appropriate position of the wire groove can be selected according to the fixing method of the fixing assembly.

[0057] If the fixing components 2-1-1 are arranged along the circumferential direction, when the fixing components 2-1-1 are arranged adjacent to each other, the side wall of the blade provided with the fixing components 2-1-1 is provided with one or more first wire grooves 2-1-4 for passing the optical cable 7 or the connector, and the first wire grooves 2-1-4 are arranged opposite to the fixing components 2-1-1; when the first stopper 2-1 includes at least two groups of fixing modules arranged at intervals, such as Figure 4 , 6 As shown, the side wall of each blade provided with a fixing module is provided with one or more first wire grooves 2-1-4 for passing the optical cable 7 or the connector so that it is completely in the sunken space of the first limiter 2-1. Each group of fixing modules corresponds to at least one first wire groove 2-1-4, and the first wire groove 2-1-4 is arranged relative to the corresponding fixing module.

[0058] If the fixing assembly 2-1-1 is arranged radially, such as Figure 1 , 3 As shown in , 5, and 9, it is necessary to open one or more second wire grooves 2-3-3 and one or more third wire grooves 2-3-4 on the side wall of the winding column 2-3, for passing the optical cable 7 or the connector, so that it is completely in the sinking space of the first limiter 2-1. When each fixed component 2-1-1 is arranged adjacent to each other, the second wire groove 2-3-3 and the third wire groove 2-3-4 are arranged opposite to each other, the second wire groove 2-3-3 is opened on the side close to the fixed component, and the third wire groove 2-3-4 is opened on the side away from the fixed component; when the first limiter 2-1 includes at least two groups of fixed modules arranged at intervals, each group of fixed modules corresponds to at least one second wire groove 2-3-3 and at least one third wire groove 2-3-4, and the second wire groove 2-3-3 and the third wire groove 2-3-4 are arranged opposite to each other, the second wire groove 2-3-3 is opened on the side close to the fixed module, and the third wire groove 2-3-4 is opened on the side away from the fixed module.

[0059] Furthermore, a winding groove 2-1-2 is formed on the first limiting member 2-1, and a plurality of second baffles 2-1-3 are preferably provided at the top of the winding groove 2-1-2. The winding groove 2-1-2 is used to guide the optical cable 7 from the bottom of the first limiting member 2-1 to the top of the first limiting member 2-1 and to wind it for a certain distance before fixing the connector on the fixing component 2-1-1, thereby ensuring that a certain margin of the optical cable 7 is left above the first limiting member 2-1, thereby improving the stability of the connector fixation and avoiding the connector from falling off when the optical cable 7 is pulled out.

[0060] Any fixing component 2-1-1 that can provide left and right limits and upper and lower limits can be applied in the present application. In order to improve the stability of the connector limit, the present application also optimizes the structure of the fixing component 2-1-1 and provides various forms of fixing components 2-1-1. The attached drawings only show a fixing schematic diagram of a connector such as an LC connector 5 or an SC connector 6. In actual applications, each fixing component 2-1-1 can be applicable to a variety of connectors including LC connectors 5 and SC connectors 6.

[0061] In a preferred embodiment of the present application, Figure 6 , 7 As shown, the fixing component 2-1-1 includes a first limiting wall 2-1-1-2 and a second limiting wall 2-1-1-4 which are arranged opposite to each other, and also includes a first limiting buckle 2-1-1-1, the first limiting wall 2-1-1-2 is elastic and a pre-tightening boss 2-1-1-3 is arranged on its inner wall, the pre-tightening boss 2-1-1-3 is used to have an interference fit with the connector 5, and prevent the connector 5 from moving left and right by cooperating with the second limiting wall 2-1-1-4 on the opposite side; preferably, when the connector is an LC connector 5, a limiting boss 2-1-1-5 is arranged on the outer wall of the second limiting wall 2-1-1-4, and the limiting boss 2-1-1-5 is located between the body of the LC connector 5 and the handle of the LC connector 5, and prevents the LC connector 5 from moving backward by abutting against the handle of the LC connector 5; the first limiting buckle 2-1-1-1 is arranged on the same side as the first limiting wall 2-1-1-2 or the second limiting wall 2-1-1-4, wherein Fig.11 , 12 This is an embodiment in which the first limiting buckle 2-1-1-1 and the first limiting wall 2-1-1-2 are arranged on the same side. Figure 3 , 4 This is an embodiment in which the first limiting buckle 2-1-1-1 and the second limiting wall 2-1-1-4 are arranged on the same side. The first limiting buckle 2-1-1-1 is close to the edge of the first limiting member 2-1 and is engaged with the upper surface of the connector 5 to prevent the connector 5 from moving upward.

[0062] In another preferred embodiment of the present application, Figure 8As shown, the fixing assembly 2-1-1 includes a second limit buckle 2-1-1-6 and a third limit buckle 2-1-1-7 which are relatively arranged. The second limit buckle 2-1-1-6 and the third limit buckle 2-1-1-7 are arranged on the left and right sides of the connector and are respectively engaged with the upper surface of the connector to prevent the connector from moving upward or left and right. At the same time, the third wire groove 2-3-4 on the winding pole 2-3 or the first wire groove 2-1-4 on the first limit member 2-1 has an interference fit with the connector or the optical cable, thereby preventing the connector from moving backward.

[0063] In another preferred embodiment of the present application, Fig. 9 As shown, the fixing component 2-1-1 includes a limit bridge 2-1-1-8 and a third limit wall 2-1-1-9. The space below the limit bridge 2-1-1-8 is used to pass the connector to prevent the connector from moving upward. The third limit wall 2-1-1-9 is connected to the limit bridge 2-1-1-8, and a pre-tightening boss 2-1-1-3 is provided on its inner wall. The pre-tightening boss 2-1-1-3 is used to have an interference fit with the connector 5 and prevent the connector 5 from moving left and right by cooperating with the limit bridge 2-1-1-8.

[0064] like Fig.11 , 12 As shown, according to another aspect of the present application, a fiber optic panel is provided, which specifically includes the above-mentioned rotating shaft unit, a base 3 and a cover body 1 covered on the outside of the base 3 and the rotating shaft unit 2, the base 3 is provided with an axis 3-1, and the winding post is rotatably matched with the axis. Preferably, the middle opening of the winding post 2-3 is sleeved on the outside of the axis 3-1, so that the rotating shaft unit 2 can rotate around the axis 3-1, so as to realize the functions of winding and pulling out the optical cable, wherein when winding the optical cable, the optical cable 7 can be manually wound around the outside of the winding post 2-3 to realize the winding function, or part of the optical cable 7 can be manually wound around the outside of the winding post 2-3, and then the winding post 2-3 is rotated in a clockwise or counterclockwise direction so that the optical cable 7 is completely wound around the outside of the winding post 2-3, so as to realize the function of winding the optical cable; when pulling out the optical cable, the winding post 2-3 will rotate in the opposite direction of the winding to release the optical cable of a suitable length, thereby realizing the function of pulling out the optical cable;

At the same time, the annular baffle 3-3 is provided with one or more outlet holes 3-3-1, which are used to lead out the optical cable and facilitate pulling. At the same time, in order to facilitate the separation of the rotating shaft unit 2 from the base 3, the annular baffle 3-3 is also provided with a wider operation opening to provide space for the user's hand operation.
