Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0032] Please seeFigures 1 to 11 This utility model provides an AOC optical module, including an MPO fiber optic connector 1. It is characterized by further including an AOC sleeve 2 for connecting the MPO fiber optic connector 1 and a base 3 for mounting the AOC sleeve 2. The end of the AOC sleeve 2 that is assembled with the MPO fiber optic connector 1 has a locking structure, and the AOC sleeve 2 is locked onto the base 3 by the locking structure. By designing the locking structure on the AOC sleeve 2, and cooperating with the limiting structure on the base 3, the MPO fiber optic connector 1 can be prevented from being pulled out of the AOC sleeve 2. This differs from existing screw-locking methods, saving material costs and simplifying the assembly process. In the prior art, screws are usually used to lock the MPO fiber optic connector 1 into the AOC sleeve 2. This embodiment cleverly utilizes the structure of the AOC sleeve 2 itself in conjunction with the structure on the base 3 to prevent the MPO fiber optic connector from being pulled out of the AOC sleeve 2, saving screw material costs and facilitating assembly by eliminating the screwing process.

[0033] Please see Figures 1 to 11 The locking structure includes two opposing elastic clamping arms 20, which cooperate to clamp the MPO fiber optic connector 1. The limiting structure restricts the opening of the two elastic clamping arms 20. Further refining the locking structure, it employs elastic clamping arms 20, thus providing a resilient clamping force to lock the MPO fiber optic connector 1 in the AOC sleeve 2, while the limiting structure restricts the opening of the two elastic clamping arms 20.

[0034] Please see Figures 1 to 11 The elastic locking arm 20 has a locking protrusion 202. The limiting structure includes a limiting component on the base 3, which abuts against the locking protrusion 202 to limit the opening of the two elastic locking arms 20. Preferably, the outer wall of the connector head 10 of the MPO fiber optic connector 1 has a slot 100, and the elastic locking arm 20 has a locking head 201 that engages with the slot 100. The locking head 201 and the locking protrusion 202 are designed on the elastic locking arm 20, wherein the locking head 201 can be fitted into the slot 100 on the base 3. The limiting component on the base 3 limits the locking protrusion 202, thereby preventing the elastic locking arms 20 from opening and thus preventing the MPO fiber optic connector 1 from being pulled out of the AOC sleeve 2. Of course, other existing locking methods are also possible besides this locking method.

[0035] Please see Figures 1 to 11The limiting component includes multiple steps 30, each step 30 decreasing progressively in the insertion direction of the MPO fiber optic connector 1, and the step surface of each step 30 facing the interior of the AOC sleeve 2. The locking boss 202 is limited between adjacent steps 30. To refine the above limiting component, steps 30 are used for limiting, such as... Figure 9 As shown, this embodiment uses two steps 30. The direction from the MPO fiber optic connector 1 to the AOC sleeve 2 is the direction of the lower step 30, that is, each step 30 decreases step by step. In this way, the locking protrusion 202 can be locked on the connecting wall between the two steps 30. When the MPO fiber optic connector 1 is to be pulled out, the locking protrusions on the two elastic locking arms 20 of the AOC sleeve 2 contact the step 30 structure on the side wall of the base 3 and cannot open, thereby preventing the MPO fiber optic connector 1 from being pulled out.

[0036] Please see Figures 1 to 11 The AOC card sleeve 2 is positioned on the base 3 by a positioning structure. In this embodiment, the AOC card sleeve 2 can be positioned on the base 3 by the positioning structure. Preferably, the positioning structure includes a positioning key 31 provided on the base 3, and the outer wall of the AOC card sleeve 2 has a positioning groove 21 for the positioning key 31 to engage. The specific positioning method can be that the positioning key 31 engages with the positioning groove 21. Of course, other existing positioning methods are also feasible, and this embodiment does not limit this.

[0037] Please see Figures 1 to 11 The optical module also includes an upper cover 4 that fits onto the base 3, and the upper cover 4 has a mounting position 40 for installing product labels. By designing the product label on the upper cover 4, it can be on a different surface from the air duct on the base 3, thereby reducing its thermal resistance to the air inlet duct and improving the module's thermal performance.

[0038] Please see Figures 1 to 11 The bottom surface of the base 3 is equipped with a heat dissipation structure. This structure dissipates heat from the optical module. The heat dissipation structure includes several partitions 32, each perpendicular to the base 3. Each partition 32 is covered by a top plate 33 parallel to the base 3. There is a gap between adjacent partitions 32. The base 3, the top plate 33, and the adjacent partitions 32 together form an air duct. The heat dissipation structure uses multiple partitions 32 to form an air duct, and the airflow within the air duct carries away the heat from the optical module. There can be multiple air ducts, depending on the number of partitions 32.

[0039] For further optimization of the above solution, please refer to [link / reference]. Figures 1 to 11The base 3 is recessed at the entrance of the air duct to form an air vent groove 34. One opposite wall of the air vent groove 34 is a through opening 35, and the wall of the air vent groove 34 relative to the entrance of the air duct is an inclined wall 36, which is inclined away from the entrance of the air duct. Using a large-sized air vent groove 34 increases the air intake surface and improves air cooling capacity. Specifically, when air enters the air vent groove 34, it is first guided into the groove by the inclined wall 36, and then flows into the air duct, increasing the airflow into the air duct and thus improving the heat dissipation effect.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
