[0029] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Now, in conjunction with the drawings, the preferred embodiments of the present invention will be described in detail.

[0030] The embodiment of the present invention provides a fixing device for an optical fiber flange 100, which is used to fix the optical fiber flange 100. As Figure 1 shown, the optical fiber flange 100 includes a flange body 110, a spring piece 120 and a limit protrusion 130 provided on the same side of the flange body 110. The spring piece 120 can be compressed to be close to the side of the flange body 110, and the spring piece 120 and the limit protrusion 130 are arranged at intervals.

[0031] As Figure 2 and Figure 3 shown, the fixing device for the optical fiber flange 100 includes a bottom plate 210 and a limit panel 220 provided on the bottom plate 210. At least one limit hole 220a for limiting the flange body 110 is provided on the limit panel 220. A first limit baffle 230 and a second limit baffle 240 are provided on the limit panel 220. The first limit baffle 230 and the second limit baffle 240 are used to abut against different sides of the flange body 110. Among them, the flange body 110 of an optical fiber flange 100 correspondingly penetrates through a limit hole 220a. When the optical fiber flange 100 is installed in place, the limit panel is clamped between the spring piece 120 and the limit protrusion 130, and the first limit baffle 230 and the second limit baffle 240 abut against different sides of the flange body 110.

[0032] The fixing device for the optical fiber flange 100 in the embodiment of the present invention is provided with a bottom plate 210 and a limit panel 220 provided on the bottom plate 210. At least one limit hole 220a is provided on the limit panel 220, and the optical fiber flange 100 can be limited from multiple directions. A first limit baffle 230 and a second limit baffle 240 are provided on the limit panel 220. When the flange body 110 of the optical fiber flange 100 correspondingly penetrates through a limit hole 220a and the optical fiber flange 100 is installed in place, the limit panel is clamped between the spring piece 120 and the limit protrusion 130, so as to limit the optical fiber flange 100 in the front and back directions. The first limit baffle 230 and the second limit baffle 240 abut against different sides of the flange body 110, effectively increasing the limit constraints on different sides of the optical fiber flange 100, reducing the possibility of the optical fiber flange 100 shaking, and improving the fixing effect of the optical fiber flange 100.

[0033] Among them, the bottom plate 210 provides support for the limit panel 220. An optoelectronic conversion device, an optical power detection device, etc. can also be placed on the bottom plate 210 to provide a placement space for other devices.

[0034] The limit holes 220a can be one, two, three or more than three, and can be set according to needs. Setting more than one on the limit panel 220 can limit and fix one or more fiber optic flanges 100. For the state diagram of limiting and fixing multiple fiber optic flanges 100, reference can be made to Figure 6 .

[0035] In an alternative embodiment of the present application, referring to Figure 2 and Figure 3 , the hole edges of the limit holes 220a include a first hole edge segment 221 and a second hole edge segment 222 located on opposite sides. The first limit baffle 230 is located on the first hole edge segment 221, and the second limit baffle 240 is located on the second hole edge segment 222.

[0036] By respectively arranging the first limit baffle 230 and the second limit baffle 240 on the first hole edge segment 221 and the second hole edge segment 222 on opposite sides, and the first limit baffle 230 and the second limit baffle 240 are located on opposite sides of the hole edge of the limit hole 220a, it can ensure that the distances and positions between the first limit baffle 230 and the second limit baffle 240 and the side surfaces of the flange body 110 are accurate. After the flange body 110 passes through the limit hole 220a and is installed in place, the first limit baffle 230 and the second limit baffle 240 can precisely abut against the opposite side surfaces of the flange body 110, clamping the flange body 110 between the first limit baffle 230 and the second limit baffle 240, limiting the opposite sides of the flange body 110, effectively increasing the limit constraint on the opposite sides of the fiber optic flange 100, and reducing the possibility of the fiber optic flange 100 shaking in these two side directions.

[0037] Specifically, referring to Figure 4 and Figure 5 , the first limit baffle 230 and the second limit baffle 240 can be located on the left and right sides of the limit hole 220a to limit the left and right sides of the flange body 110 and reduce the shaking of the fiber optic flange 100 in the left and right directions.

[0038] Continue to refer to Figure 2 and Figure 3, the hole edge of the limiting hole 220a further includes a third hole edge section 223 and a fourth hole edge section 224 located on opposite sides. The first hole edge section 221, the third hole edge section 223, the second hole edge section 222, and the fourth hole edge section 224 are sequentially connected to enclose the limiting hole 220a. The first limiting baffle 230 extends from the third hole edge section 223 along the length direction of the first hole edge section 221 to the fourth hole edge section 224, and the second limiting baffle 240 extends from the third hole edge section 223 along the length direction of the second hole edge section 222 to the fourth hole edge section 224.

[0039] By extending the first limiting baffle 230 and the second limiting baffle 240 from the third hole edge section 223 to the fourth hole edge section 224, the abutting area between the first limiting baffle 230 and the second limiting baffle 240 and the flange body 110 can be increased, and the abutting area between the first limiting baffle 230 and the second limiting baffle 240 and the optical fiber flange 100 can be increased, so that the stress area between the optical fiber flange 100 and the first limiting baffle 230 is larger, and the stress area between the optical fiber flange 100 and the second limiting baffle 240 is larger, improving the stability and reliability of abutting and limiting the optical fiber flange 100, and further reducing the possibility of the optical fiber flange 100 shaking.

[0040] In other embodiments, the first limiting baffle 230 may not extend from the third hole edge section 223 to the fourth hole edge section 224, but be located on a certain section of the first hole edge section 221, and may also abut against one side surface of the flange body 110 to realize the lateral limiting of one side of the flange body 110. Similarly, the second limiting baffle 240 may not extend from the third hole edge section 223 to the fourth hole edge section 224, but be located on a certain section of the second hole edge section 222, and may also abut against another side surface of the flange body 110 to realize the lateral limiting of the other side of the flange body 110.

[0041] Or, in another embodiment, a plurality of first limiting baffles 230 are provided, and the plurality of first limiting baffles 230 are spaced apart and arranged along the length direction of the first hole edge section 221. The plurality of first limiting baffles 230 can abut against different positions on the same side surface of the flange body 110, increasing the contact area with the same side surface of the flange body 110, and jointly limiting the flange body 110 from the same side. The plurality of first limiting baffles 230 can be evenly distributed or not evenly distributed, and can all realize abutting against different positions on the same side surface of the flange body 110.

[0042] There are multiple second limiting baffles 240, and the multiple second limiting baffles 240 are arranged at intervals along the length direction of the second hole edge section 222. The multiple second limiting baffles 240 can abut against different positions on the same side of the flange body 110, increasing the contact area with the same side of the flange body 110, and jointly limiting the flange body 110 from the same side. The multiple second limiting baffles 240 can be evenly distributed or not evenly distributed, and both can achieve abutting against different positions on the same side of the flange body 110.

[0043] In the embodiment of the present application, it is preferably that both the first limiting baffle 230 and the second limiting baffle 240 extend from the third hole edge section 223 to the fourth hole edge section 224, which can improve the stability and reliability of abutting and limiting the optical fiber flange 100, further reduce the possibility of the optical fiber flange 100 shaking, and the assembly or process is relatively simple.

[0044] Reference Figure 5 , in an alternative embodiment of the present application, the first limiting baffle 230 is integrally formed with the limiting panel 220, which can reduce the number of components of the overall fixing device, simplify the manufacturing process, reduce the production cost, and improve the production efficiency; eliminate the joint between the first limiting baffle 230 and the limiting panel 220, reduce the possibility of the first limiting baffle 230 loosening or falling off, and the overall structural strength is higher, which is beneficial to improving the stability and reliability of the fixing device.

[0045] Furthermore, the second limiting baffle 240 is integrally formed with the limiting panel 220. Similarly, the second limiting baffle 240 being integrally formed with the limiting panel 220 can reduce the number of components of the overall fixing device, simplify the manufacturing process, reduce the production cost, and improve the production efficiency; eliminate the joint between the second limiting baffle 240 and the limiting panel 220, reduce the possibility of the second limiting baffle 240 loosening or falling off, and the overall structural strength is higher, which is beneficial to improving the stability and reliability of the fixing device.

[0046] Furthermore, both the first limiting baffle 230 and the second limiting baffle 240 are perpendicular to the limiting panel 220, and the hole wall of the limiting hole 220a is perpendicular to the limiting panel 220. The limiting panel 220 can better support the first limiting baffle 230 and the second limiting baffle 240, making the connection between the first limiting baffle 230 and the second limiting baffle 240 and the limiting panel more firm, reducing the risk of loosening or deformation, and increasing the contact area between the first limiting baffle 230 and the second limiting baffle 240 and the corresponding side of the flange body 110, further improving the fixing effect of the optical fiber flange 100.

[0047] In other embodiments, the first limiting baffle 230 and the second limiting baffle 240 may also be inclined with respect to the limiting panel 220 to form a preset angle. The hole wall of the limiting hole 220a is inclined with respect to the limiting panel 220 to form the same preset angle, which can also achieve that the first limiting baffle 230 and the second limiting baffle 240 abut against different sides of the flange body 110 to limit different lateral directions of the flange body 110. In the embodiments of the present application, it is preferably that both the first limiting baffle 230 and the second limiting baffle 240 are perpendicular to the limiting panel 220, and the hole wall of the limiting hole 220a is perpendicular to the limiting panel 220, so that the overall structure is more stable and the fixing effect of the optical fiber flange 100 is further improved.

[0048] In an alternative embodiment of the present application, the limiting panel 220 is perpendicular to the bottom plate 210. The bottom plate 210 can better support the limiting panel 220, making the connection between the limiting panel 220 and the bottom plate 210 firmer and reducing the risk of loosening or deformation of the limiting panel 220.

[0049] In other embodiments, the limiting panel 220 may also be inclined with respect to the bottom plate 210. The limiting hole 220a, the first limiting baffle 230 and the second limiting baffle 240 on the limiting panel 220 can all limit the flange body 110, and the optical fiber flange 100 is fixedly installed on the limiting panel 220.

[0050] An embodiment of the present utility model further provides an optical module, which includes at least one optical fiber flange 100 and a fixing device for the optical fiber flange 100 as described above. The optical fiber flange 100 includes a flange body 110, a spring piece 120 and a limiting protrusion 130 provided on the same side of the flange body 110. The spring piece 120 can be compressed to be close to the side of the flange body 110. The spring piece 120 and the limiting protrusion 130 are arranged at intervals. The flange body 110 of an optical fiber flange 100 correspondingly passes through a limiting hole 220a. When the optical fiber flange 100 is installed in place, the limiting panel is clamped between the spring piece 120 and the limiting protrusion 130, and the flange body 110 abuts against the first limiting baffle 230 and the second limiting baffle 240.

[0051] In the fixing device of the fiber optic flange 100 in the optical module according to the embodiment of the present utility model, by providing a bottom plate 210 and a limiting panel 220 provided on the bottom plate 210, at least one limiting hole 220a is provided on the limiting panel 220, and the fiber optic flange 100 can be limited from multiple directions. A first limiting baffle 230 and a second limiting baffle 240 are provided on the limiting panel 220. When the flange body 110 of the fiber optic flange 100 correspondingly passes through a limiting hole 220a and the fiber optic flange 100 is installed in place, the limiting panel is clamped between the elastic piece 120 and the limiting protrusion 130 to realize the limitation of the fiber optic flange 100 in the front and rear directions. The first limiting baffle 230 and the second limiting baffle 240 abut against different sides of the flange body 110, effectively increasing the limiting constraints on different sides of the fiber optic flange 100, reducing the possibility of the fiber optic flange 100 shaking, and improving the fixing effect of the fiber optic flange 100.

[0052] Among them, other components in the optical module, such as an optoelectronic conversion circuit, an optical power detection component, etc., can be installed in the space formed by the limiting panel 220 and the bottom plate 210.
