[0045] This application provides an optical fiber fixing mechanism 100, as Figure 1 shown, including:

[0046] A base 1, on which an optical fiber accommodating portion 10 for accommodating an optical fiber is formed. The number of optical fibers that each optical fiber accommodating portion 10 can accommodate and the number of optical fiber accommodating portions 10 provided in the optical fiber fixing mechanism 100 can also be multiple, which can be set according to actual needs without limitation. The projection of the base 1 in the vertical direction is nearly rectangular. At the edge of the short side of the rectangle of the base 1, a connecting arm 11 can be provided for fixing the base 1 to a target position, for example, on the main board of a network device, provided at the edge of an optical engine;

[0047] A rotating cover 2, corresponding to the optical fiber accommodating portion 10. One side of the rotating cover 2 is rotatably connected to the base 1. The rotation of the rotating cover 2 relative to the base 1 can be achieved by pin-connecting the rotating cover 2 and the base 1. The rotating cover 2 rotates around the pin as an axis. When the rotating cover 2 is opened, the optical fiber accommodating portion 10 can be exposed to facilitate a worker to set the optical fiber in the optical fiber accommodating portion 10. When the rotating cover 2 is closed, it can block the optical fiber accommodating portion 10 to fix the placed optical fiber through structures such as the rotating cover 2;

[0048] A flexible filling member 3, provided between the base 1 and the rotating cover 2. The flexible filling member 3 can be selected according to needs. For example, silicone and epoxy resin can be selected. The silicone can be formed in the form of silicone foam or others, without limitation thereto. The number of the flexible filling members 3 can be consistent with the number of the optical fiber accommodating portions 10. The flexible filling members 3 can be separately provided in multiple parts or can be formed as a whole and correspond to multiple optical fiber accommodating portions 10, which can be set according to actual needs;

[0049] A fixing member 4 is provided on the rotating cover 2. The fixing member 4 can be a screw, a non-loosening screw, a snap, etc., and the fixing member 4 can be fixed to the base 1. Specifically, it can be screwed or snapped, etc.

[0050] Among them, the fixing member 4 sequentially passes through the rotating cover 2 and the flexible filling member 3 and is fixedly connected to the optical fiber accommodating portion 10. The flexible filling member 3 and the optical fiber accommodating portion 10 clamp the optical fiber accommodated in the optical fiber accommodating portion 10.

[0051] As Figure 2 shown, when assembling the network device 200, the optical engine 301 is welded on the main board 300, and the optical fiber 302 connected to the optical engine 301 is led out. There are screw holes provided on the main board 300, and the screw holes and the connecting arm 11 can be connected by screws or the like to fix the optical fiber fixing mechanism 100 on the main board 300.

[0052] After the installation is completed, the operator can turn over the fixing member 4 to open the rotating cover 2 to expose the optical fiber accommodating portion 10, and put the optical fiber 302 of the optical engine 301 into the optical fiber accommodating portion 10. Thereafter, the operator can continue to operate the fixing member 4 to close the rotating cover 2 towards the optical fiber accommodating portion 10, so as to press the flexible filling member 3 through the rotating cover 2 and the optical fiber accommodating portion 10, so that the flexible filling member 3 can be squeezed into the optical fiber accommodating portion 10 to fix the optical fiber 302 in the optical fiber accommodating portion 10.

[0053] The rotating cover 2 and the optical fiber accommodating portion 10 on the base 1 are fixed by the fixing member 4 with adjustable spacing. Since the spacing between the rotating cover 2 and the base 1 can be adjusted by the fixing member 4, and the optical fiber accommodating portions 10 on the rotating cover 2 and the base 1 clamp the flexible filling member 3, the pressing degree between the flexible filling member 3 and the optical fiber 302 can be changed, so that the optical fiber 302 can be tightly clamped in the optical fiber fixing mechanism 100, avoiding the disconnection of the connection between the optical fiber 302 and the optical engine 301 caused by the pulling of the optical fiber 302, improving the stability of the use of the optical engine and the optical fiber in the network device, and improving the reliability of the network device.

[0054] Optionally, as Figure 3 shown, the optical fiber accommodating portion 10 includes:

[0055] A receiving groove 10A for receiving and arranging the optical fiber accommodated in the optical fiber accommodating portion 10. The receiving groove 10A can be nearly U-shaped on the base 1, so that the receiving groove 10A can be closer to the shape of the optical fiber.

[0056] A boss 10B formed on at least one side of the receiving groove 10A. The boss 10B is provided on at least one side of the receiving groove 10A means as Figure 3In the positional relationship shown, the boss 10B is located on at least one side of the left and right sides of the receiving groove 10A. For example, in a fiber optic receiving portion 10, if there is one receiving groove 10A provided, the boss 10B can be located on its left or right side. If there are two or more receiving grooves 10A provided, the boss 10B can be provided between two adjacent receiving grooves 10A, that is, it is located on the left side of one receiving groove 10A and on the right side of another receiving groove 10A.

[0057] Wherein, the fixing member 4 is fixed to the boss 10B.

[0058] In the fiber optic receiving portion 10, the fixing member 4 can be provided on the boss 10B that is higher than the receiving groove 10A, or can be provided at other positions of the fiber optic receiving portion 10. Taking the case of being provided on the boss 10B as an example, there can be structures on the boss 10B that cooperate with the fixing member 4, such as screw holes and buckles, etc., and they are connected in a way that can adjust the distance between the base 1 and the rotating cover 2.

[0059] Optionally, as Figure 4 shown, a downward pressing limit block 10C extends from the boss 10B towards the rotating cover 2.

[0060] In some cases, in order to be able to limit the rotating cover 2 from pressing down on the flexible filling member 3 excessively, a downward pressing limit block 10C facing the rotating cover 2 can be provided on the boss 10B.

[0061] The downward pressing limit block 10C is slightly higher than the boss 10B and slightly lower than the height when the flexible filling member 3 is placed in the fiber optic receiving portion 10. As Figure 4 shown, the flexible filling member 3 is placed on the upper side of the fiber optic receiving portion 10, abutting against the two sides of the boss 10B and the receiving groove 10A. When the rotating cover 2 is rotated to cover the flexible filling member 3, the distance from the lower surface 2A of the rotating cover 2 to the downward pressing limit block 10C is h. That is to say, when the rotating cover 2 is further pressed down, it can be pressed down at most by h. This enables the flexible filling member 3 to be compressed by at most h. During the pressing down process, the flexible filling member 3 will be pressed into the receiving groove 10A, further squeezing the optical fiber 302, thereby fixing the optical fiber 302 more firmly in the optical fiber fixing mechanism 100. And since the maximum distance that can be pressed down is h, excessive pressing down to damage the optical fiber 302 can be avoided during the process of pressing down the rotating cover 2.

[0062] Specifically, as Figure 4 shown, there are two downward pressing limit blocks 10C, respectively corresponding to the opposite side edges 2C, 2D of the rotating cover 2;

[0063] The flexible filling member 3 includes:

[0064] A connecting portion 30 is disposed between the downward-pressing limit blocks 10C, and the fixing member 4 passes through the connecting portion 30;

[0065] The filling portion 31 corresponds to the receiving groove 10A and extends from the connecting portion 30 to the edge 1A, 1B of the base 1 .

[0066] For the flexible filling member 3, its connecting portion 30 and the filling portion 31 are Figure 5 The top view of the optical fiber receiving portion 10 is nearly H-shaped. When the number of receiving grooves 10A provided in the optical fiber receiving portion 10 increases, the optical fiber receiving portion 10 is nearly continuous H-shaped. However, if only one receiving groove 10A is provided in the optical fiber receiving portion 10,

[0067] Optional, such as Figure 5 As shown, the flexible filling member 3 further includes:

[0068] The supporting portion 32 is disposed in the receiving groove 10A, and the optical fiber 302 received in the receiving groove 10A is clamped by the supporting portion 32 and the filling portion 31 .

[0069] like Figure 5 As shown, the left rotating cover 2 is flipped open and the flexible filling member 3 is staggered to expose the optical fiber accommodating portion 10, and the right rotating cover 2 is closed to seal the optical fiber accommodating portion 10. The flexible filling member 3 can be set as a two-part structure according to needs, one part is an integrated connecting portion 30 and a filling portion 31, which are placed on the boss 10B, and the other part is a supporting portion 32 that is separated from the connecting portion 30 and the filling portion 31 and is placed in the accommodating groove 10A.

[0070] When the optical fiber 302 is placed in the receiving groove 10A, the support portion 32 can support the optical fiber 302 to prevent the bottom wall of the receiving groove 10A from scratching the optical fiber 302 when the optical fiber 302 is squeezed, thereby further improving the reliability of fixing the optical fiber 302.

[0071] Optional, such as Figure 6 As shown, a fixing hole 10D of a preset depth is formed on the boss 10B. When the fixing member 4 fixes the rotating cover 2 through the fixing hole 10D, the height to which the rotating cover 2 can be pressed down can be limited by the depth of the fixing hole 10D;

[0072] The fixing member 4 cooperates with the fixing hole 10D to fix the rotating cover 2 and the flexible filling member 3 to the base 1 .

[0073] When the rotating cover 2 is rotated to cover the flexible filling member 3, the height from the upper surface of the boss 10B to the bottom of the fixing hole 10D is h. That is to say, after continuously pressing down the rotating cover 2, it can be pressed down by at most h, which enables the flexible filling member 3 to be compressed by at most h. During the pressing process, the flexible filling member 3 will be recorded into the receiving groove 10A, further squeezing the optical fiber 302, so as to more firmly fix the optical fiber 302 in the optical fiber fixing mechanism 100. And since the maximum distance that can be pressed down is h, over-pressing and damaging the optical fiber 302 can be avoided during the process of pressing down the rotating cover 2.

[0074] Optionally, the receiving groove 10A and the boss 10B are arranged at intervals.

[0075] Since the number of the receiving grooves 10A can be set to two or more, if the position of the boss 10B deviates, it may cause the rotating cover 2 to incline towards one side of the receiving groove 10A during the pressing process, which will result in different degrees of extrusion of the optical fiber 302 in each receiving groove 10A, and it is difficult to achieve balanced fixation.

[0076] To avoid the above problems, the receiving groove 10A and the boss 10B can be arranged at intervals, so that the boss 10B can reliably support the rotating cover 2, avoid the unbalanced situation of the flexible filling member 3 in multiple receiving grooves 10A, and further improve the reliability of the optical fiber fixing mechanism 100 for fixing the optical fiber 302.

[0077] Optionally, the number of the optical fiber receiving parts 10 is at least two; a partition table 12 is arranged between two adjacent optical fiber receiving parts 10.

[0078] Since the rotating cover 2 corresponds to the optical fiber receiving part 10, therefore, in the case of including multiple optical fiber receiving parts 10, multiple rotating covers 2 also need to be provided. To avoid interference between multiple rotating covers 2, a partition table 12 can be arranged between adjacent optical fiber receiving parts 10 to isolate the optical fiber receiving parts 10, so that the rotating covers 2 can also be separated from each other, avoiding the situation of interference between the rotating covers 2.

[0079] Optionally, the fixing member 4 is a non-loosening screw; or, the fixing member 4 is a screw;

[0080] The flexible filling member 3 is a silica gel foam.

[0081] Of course, the specific structure of the fixing member 4 can be set according to actual needs, and the flexible filling member 3 can also be selected according to actual needs.

[0082] Correspondingly, the present application also provides a network device 200, as Figure 2 shown, including:

[0083] Main board 300;

[0084] Optical engine 301, electrically connected to the main board 300, and an optical fiber 302 extends from one side of the optical engine 301;

[0085] The optical fiber fixing mechanism 100 described in any one of the above is fixed to the main board 300, and the optical fiber 302 is clamped between the optical fiber accommodating portion 10 and the flexible filling member 3 by rotating the cover 2.

[0086] The technical solutions provided in the embodiments of this specification may include the following beneficial effects:

[0087] In the embodiments of this specification, by the cooperation of the fixing member, the rotating cover and the base, the compression degree of the flexible filling member is adjusted to meet the fixing of the optical fiber accommodated in the optical fiber accommodating portion, avoiding damage to the optical fiber led out by the optical engine due to pulling during the installation process of the network device, and improving the reliability of the network device applying the optical fiber.
