[0034] The housing 210 includes a panel 211 and a bottom plate 212 fixedly connected to the panel 211. At least one first limiting hole 211a for limiting the flange body 110 is formed on the panel 211, and the first limiting hole 211a can limit the flange body 110 from the upper, lower, left and right directions.

[0035] The limiting plate 220 is fixedly connected to the fixing plate 230 and is arranged at an interval from the panel 211. At least one second limiting hole 220a for limiting the flange body 110 is formed on the limiting plate 220. The second limiting hole 220a is arranged in one-to-one correspondence with the first limiting hole 211a, and the fixing plate 230 can be fixed on the bottom plate 212. The second limiting hole 220a can limit the flange body 110 from the upper, lower, left and right directions.

[0036] Wherein, the flange body 110 of an optical fiber flange 100 correspondingly passes through a second limiting hole 220a and a first limiting hole 211a. When the optical fiber flange 100 is installed in place, the panel 211 is clamped between the spring piece 120 and the limiting protrusion 130, and the flange body 110 is limited in the first limiting hole 211a and the second limiting hole 220a.

[0039] In an alternative embodiment of the present application, refer to Figure 2 and Figure 4 , the fixing plate 230 and the limiting plate 220 are perpendicularly arranged to each other. The fixing plate 230 and the limiting plate 220 are perpendicularly arranged to each other, and the center of gravity of the limiting plate 220 is on the vertical line of the limiting plate 220 and the fixing plate 230, so that the fixing plate 230 can more stably support the limiting plate 220, reduce the instability of the limiting plate 220 during use, and improve the overall structural stability.

[0045] In an alternative embodiment of the present application, the width of the fixing plate 230 is greater than the height of the limiting plate 220. The fixing plate 230 can provide a larger supporting area, increase the stability of the limiting plate 220 fixed on the bottom plate 212, reduce the inclination or swing of the limiting plate 220 during use, and further improve the stability of the fixing of the optical fiber flange 100. The width direction of the fixing plate 230 is as Figure 4 shown in the X-axis direction as Figure 4 shown, and the height direction of the limiting plate 220 is as

[0046] Reference Figure 2, in an alternative embodiment of the present application, the fixing device 200 of the fiber optic flange further includes a fixing member 240.

The way that the fixing member 240 cooperates with the first mounting hole and the second mounting hole to realize the fixation of the fixing plate 230 and the bottom plate 212 is simple and fast in assembly, improving the assembly efficiency.

[0048] Specifically, the fixing member 240 can be a screw, and internal threads matching the external threads of the screw are provided on the hole walls of both the first mounting hole and the second mounting hole. Through the cooperation of the external thread and the internal thread, a firm connection between the fixing plate 230 and the bottom plate 212 can be achieved, and the assembly is simple.

[0049] In other embodiments, the fixing member 240 can be a bolt, which passes through the first mounting hole and the second mounting hole to realize a firm connection between the fixing plate 230 and the bottom plate 212.

[0050] In other embodiments, it can also be that a buckle is provided on one of the fixing plate 230 and the bottom plate 212, and a corresponding card slot is provided on the other, and the buckle can be engaged in the corresponding card slot to also realize the fixed connection between the fixing plate 230 and the bottom plate 212.

The length direction of the fixing plate 230 is as Figure 4 shown in the Y-axis direction.

[0052] Multiple first limiting holes 211a and multiple second limiting holes 220a can limit and fix multiple optical fiber flanges 100 on the panel 211 and the limiting plate 220. Users can also select the first limiting holes 211a and the second limiting holes 220a at appropriate positions according to needs to limit and install the optical fiber flanges 100, with higher selectivity and flexibility.

[0053] Multiple fixing members 240 are arranged at intervals along the length direction of the fixing plate 230, consistent with the distribution direction of the multiple first limiting holes 211a and the second limiting holes 220a, ensuring uniform distribution of the force between the fixing plate 230 and the bottom plate 212, reducing the possibility of loosening between the fixing plate 230 and the limiting plate 220, and enabling the limiting plate 220 that limits multiple optical fiber flanges 100 to be more firmly fixed on the bottom plate 212, further improving the stability of the fixing of the optical fiber flanges 100.

The elastic piece 120 is compressed and deformed under the pressure of the hole wall of the first limiting hole 211a and is close to the side surface of the flange body 110.
