Description

Technical Field

[0002] With the rapid development of 5G technology, the performance and stability of optical modules as core components of data transmission have become particularly important. As a key structure to protect and support the internal components of optical modules, the optical module housing not only carries the function of physical protection, but also affects the overall heat dissipation performance and electromagnetic shielding effect of the module. Under the high-speed and high-data-volume transmission requirements of 5G communications, the design of optical module housings faces new challenges. The structural design and manufacturing process of the optical module housing are directly related to the working efficiency and life of the optical module.

[0003] With the advancement of manufacturing technology, the production efficiency and precision of optical module housings are also constantly improving. At present, the structure of the 5G optical module housing is mainly a housing structure that buckles up and down, which means that the 5G optical module housing needs to be produced by pressing.

For example, patent CN114063226B (application number: CN202010780696.X) provides an optical module housing, which includes a first housing and a second housing, wherein the first housing includes a first bottom plate and side walls on both sides thereof; the second housing includes a second bottom plate and a heat dissipation structure, the heat dissipation structure includes two flaky ribs extending along the length direction of the housing on both sides of the second bottom plate; the second housing is covered on the first housing, and the first bottom plate, the side walls on both sides of the first bottom plate and the second bottom plate form a cavity; the flaky ribs on both sides of the second bottom plate are at least partially attached to one side of the side wall, so that the flaky ribs are thermally connected to the side of the side wall. The shell in patent CN114063226B reduces the contact thermal resistance between the two shells, but it still needs to be aligned and then snapped together during assembly.

[0035] The following is a detailed description of a 5G optical module housing structure provided in an embodiment of the present application with reference to specific examples.

Figure 4 for Figure 3 A schematic diagram of the local structure at A of the assembled state of a 5G optical module housing structure, as shown in FIG. Figures 1 to 4 As shown, the shell structure of the 5G optical module includes a base 1 and a cover 2, the base 1 includes a fixing portion 11, a connecting portion 12 and a bayonet portion 13, and fixing ports 111 for fixing the optoelectronic component 3 are provided on both sides of the fixing portion 11. The cross-section of the fixing portion 11 is a rectangular frame structure, and the contact of the optoelectronic component 3 is arranged at one end of the base 1 where the fixing portion 11 is located, and the end of the base 1 where the bayonet portion 13 is located is used to connect the pull ring, the connecting portion 12 is provided with a slot 121 arranged along the length direction of the base 1, and the bayonet portion 13 is provided with a card groove 131 arranged along the length direction of the base 1. The cover body 2 includes an insert plate portion 21, a rotating shaft 22 and an insert portion 23. The insert plate portion 21 is arranged at the top of the side wall of the first end of the cover body 2, the insert portion 23 is arranged at the bottom of the side wall of the second end of the cover body 2, and the rotating shaft 22 is arranged at the bottom of the side wall in the middle of the cover body 2. The insert plate portion 21 is used to be inserted into the fixing portion 11, and the side wall of the cover body 2 forms an inclined wedge-shaped portion 24 from the insert plate portion 21 to the rotating shaft 22. The rotating shaft 22 can be inserted into the slot 121 and can rotate in the slot 121. The insert portion 23 is used to be inserted into the card slot 131 to fix the cover body 2.

[0037] like Figures 1 to 4 As shown, in terms of structure, the base 1 is the bottom fixing structure of the optical module housing, and the optoelectronic component 3 of the optical module can be installed and fixed through the base 1.

[0038] Structurally, the base 1 includes a fixing portion 11, a connecting portion 12 and a bayonet portion 13, which are arranged in sequence on the base 1. Fixing ports 111 for fixing the optoelectronic component 3 are provided on both sides of the fixing portion 11, and the optoelectronic component 3 can be fixed through the fixing ports 111.

[0039] Exemplarily, a support structure for supporting the optoelectronic component 3 may be provided on the base 1 at one end away from the fixing portion 11 , so as to facilitate supporting and fixing the optoelectronic component 3 when the optical module is assembled.

[0040] Structurally, the cross section of the fixing portion 11 is a rectangular frame structure, so that a complete external shell structure of the optical module can be formed at the fixing portion 11 in the circumferential direction, making the structure of the fixing portion 11 more stable.

[0041] Structurally, the contact of the optoelectronic component 3 is arranged at one end of the base 1 where the fixing part 11 is located, so that the end where the fixing part 11 is located can be used as an insert into the switch, and the corresponding contact of the optoelectronic component 3 can exchange data with the switch. Since the optical module forms a complete external shell structure of the optical module at the fixing part 11 in the circumferential direction, the structural accuracy at the fixing part 11 is higher, which can ensure the manufacturing accuracy of the optical module and is suitable for the use of optical modules with higher speeds.

[0042] Structurally, one end of the base 1 where the bayonet portion 13 is located is used to connect the pull ring, and the base 1 can be pulled through the pull ring to pull the optical module. The optical module forms a complete external shell structure of the optical module in the circumferential direction at the fixing portion 11, which can ensure the structural stability of the optical module when removing the optical module from the switch.

[0043] like Figure 1 As shown, the connecting portion 12 is provided with a slot 121 arranged along the length direction of the base 1, and the bayonet portion 13 is provided with a card slot 131 arranged along the length direction of the base 1, and the cover body 2 can be fixed by the slot 121 and the card slot 131.

[0044] like Figure 1 As shown, the cover body 2 includes an inserting plate portion 21 , a rotating shaft 22 and an inserting portion 23 , and the inserting plate portion 21 , the rotating shaft 22 and the inserting portion 23 are sequentially arranged on the cover body 2 .

[0045] like Figures 1 to 4 As shown, the plug-in plate portion 21 is disposed at the top of the side wall of the first end of the cover body 2 , and the plug-in plate portion 21 is used to be inserted into the fixing portion 11 , so that the plug-in plate portion 21 can cooperate with the cover body 2 to fix the plug-in plate portion 21 .

[0046] like Figures 1 to 4 As shown, the plug-in portion 23 is disposed at the bottom of the side wall of the second end of the cover body 2 , and the plug-in portion 23 is used to be inserted into the card slot 131 to fix the cover body 2 , so that the plug-in portion 23 can cooperate with the card slot 131 to fix the cover body 2 .

[0047] like Figures 1 to 4 As shown, the shaft 22 is arranged at the bottom of the side wall in the middle of the cover body 2, and the side wall of the cover body 2 forms an inclined wedge-shaped portion 24 from the plug-in plate portion 21 to the shaft 22. The cover body 2 can be inserted into the fixing portion 11 at an angle through the wedge-shaped portion 24, which is convenient for assembling the optical module. The shaft 22 can be inserted into the slot 121 and can rotate in the slot 121.

[0048] When assembling the optical module housing, Figure 2 As shown, the optoelectronic component 3 can be first placed on the fixing port 111 and fixed through the fixing port 111; the cover body 2 can be inserted into the fixing portion 11 at an angle through the inclined structure at the wedge-shaped portion 24, and the rotating shaft 22 can be inserted into the slot 121 and rotated in the slot 121, so that the cover body 2 is rotated to a position parallel to the base 1.

[0049] like Figure 3 As shown, after the cover body 2 is rotated to a position parallel to the base 1, the cover body 2 can then be pushed horizontally onto the base 1, and the plug-in portion 23 is used to be inserted into the card slot 131 to fix the cover body 2. The rotating shaft 22 slides in the slot 121 to fix the rotating shaft 22, so that the cover body 2 and the base 1 can be assembled, thereby improving the assembly efficiency of the cover body 2 and the base 1. The optical module housing is not a snap-fit ​​structure, so that the optical module housing is not easily misplaced.

[0050] The beneficial effect brought by the above implementation method is that the optical module forms a complete external shell structure of the optical module in the circumferential direction at the fixing part, so that the structural accuracy at the fixing part is higher, the manufacturing accuracy of the optical module can be guaranteed, and it is suitable for use in optical modules with higher speeds.

[0051] The beneficial effect brought about by the above-mentioned implementation method is that the end where the bayonet portion is located on the base is used to connect the pull ring, and the optical module forms a complete external shell structure of the optical module in the circumferential direction at the fixed portion, which can ensure the structural stability of the optical module when removing the optical module from the switch and avoid damage to the optical module.

[0052] The beneficial effect brought by the above implementation is that the plug-in part can be inserted into the fixing part to fix the plug-in part, and the plug-in part can cooperate with the card slot to fix the cover body, thereby ensuring the fixing stability of the optical module housing.

[0053] The beneficial effect brought about by the above-mentioned implementation method is that the cover body can be inserted into the fixing part at an angle through the inclined structure at the wedge-shaped part, and at the same time, the rotating shaft is inserted into the slot and can rotate in the slot. After the cover body is rotated to a position parallel to the base, the cover body can then be pushed horizontally onto the base, so that the assembly of the cover body and the base can be realized, thereby improving the assembly efficiency of the cover body and the base. The optical module housing is not a snap-fit ​​structure, so that the optical module housing is not easy to be misplaced.

[0054] In some implementations, a rounded corner portion 241 is provided at the end of the wedge-shaped portion 24 close to the rotating shaft 22 , and the rounded corner portion 241 enables the inserting plate portion 21 to rotate around the rotating shaft 22 when the rotating shaft 22 is located in the slot 121 .

[0055] like Figure 1 and Figure 2 As shown, a rounded corner portion 241 is provided at the end of the wedge-shaped portion 24 close to the rotating shaft 22. By providing the rounded corner portion 241, the plug-in portion 21 can rotate around the rotating shaft 22 when the rotating shaft 22 is located in the slot 121, thereby assembling the cover body 2 and the base 1.

[0056] Exemplarily, the fillet radius of the fillet portion 241 may be 100 mm to 120 mm.

[0057] The beneficial effect brought about by the above implementation method is that the rounded corner portion enables the inserting plate portion to rotate around the rotating shaft when the rotating shaft is located in the slot, which facilitates the assembly of the cover body and the base and improves the assembly efficiency of the cover body and the base.

[0058] In some implementations, the length of the slot 121 is greater than that of the card slot 131, the cross-section of the shaft 22 is circular, the end of the slot 121 close to the fixing portion 11 is circular, and the plug-in portion 23 and the card slot 131 are rectangular in shape.

[0059] like Figures 1 to 3 As shown, the length of the slot 121 is greater than the length of the card slot 131, so that when the plug-in portion 23 is inserted into the card slot 131 to fix the cover body 2, the shaft 22 can always slide in the slot 121, further ensuring the efficiency of assembling the cover body and the base.

[0060] like Figures 1 to 3 As shown, the cross-section of the rotating shaft 22 is circular, and the end of the slot 121 close to the fixing portion 11 is circular, so that the rotating shaft 22 with a circular cross-section can rotate smoothly in the slot 121, and the ends of the rotating shaft 22 and the slot 121 can cooperate with each other, which is convenient for assembling the base 1 and the cover 2.

[0061] like Figures 1 to 3 As shown, the plug-in portion 23 and the card slot 131 are in a rectangular shape, so that the plug-in portion 23 and the card slot 131 can cooperate with each other for stable positioning.

[0062] The beneficial effect brought about by the above implementation method is that when the plug-in portion is inserted into the slot to fix the cover body, the rotating shaft always slides in the slot, further ensuring the efficiency of assembling the cover body and the base.

[0063] The beneficial effect brought about by the above implementation method is that the rotating shaft with a circular cross-section is easy to rotate smoothly in the slot, and the ends of the rotating shaft and the slot can cooperate with each other, which is convenient for assembling the base and the cover body and ensures the assembly accuracy of the base and the cover body.

[0064] The beneficial effect brought about by the above implementation manner is that the plug-in portion and the card slot are rectangular in shape, so that the plug-in portion and the card slot can cooperate with each other for stable positioning.

[0065] In some implementations, the fixing portion 11 and the plugging plate portion 21 are connected by fixing screws 112 .

[0066] like Figure 4 As shown, when the fixing portion 11 and the plug-in plate portion 21 are plugged together, the fixing portion 11 and the plug-in plate portion 21 are connected by fixing screws 112, which can ensure that the fixing portion 11 and the plug-in plate portion 21 are stably connected and fixed.

[0067] Exemplarily, the number of the fixing screw 112 used to fix the fixing portion 11 and the plugging plate portion 21 may be one.

[0068] The beneficial effect brought about by the above implementation manner is that when the fixing part and the plug-in plate part are plugged in and connected by fixing screws, it is possible to ensure that the fixing part and the plug-in plate part are stably connected and fixed.

[0069] The beneficial effect brought about by the above-mentioned implementation method is that when the fixing part and the plug-in part are plug-fitted, the number of fixing screws used to fix the fixing part and the plug-in part is greatly reduced, the stability of the connection between the base and the cover body is improved, and the assembly efficiency of the optical module housing is improved.

[0070] In some implementations, the fixing opening 111 includes a plurality of positioning bumps 111 a , the bottoms of which are provided with support portions 111 b for supporting the optoelectronic component 3 , and the plurality of positioning bumps 111 a are used to fix the optoelectronic component 3 in the length direction of the base 1 .

Figure 5 As shown, the fixing opening 111 includes a plurality of positioning protrusions 111 a for fixing the optoelectronic component 3 in the length direction of the base 1 , so that the plurality of positioning protrusions 111 a can cooperate with each other to assemble the optoelectronic component 3 in the transverse direction.

[0072] like Figure 4 As shown, a supporting portion 111 b for supporting the optoelectronic component 3 is provided at the bottom of the plurality of positioning protrusions 111 a . The optoelectronic component 3 can be supported by the supporting portion 111 b , so that the optoelectronic component 3 can be easily assembled.

[0073] The beneficial effect brought about by the above implementation manner is that the optoelectronic component 3 can be supported by the support portion, which facilitates the assembly of the optoelectronic component.

[0074] In some implementations, a first thermally conductive silicone rubber 113 for heat conduction is provided on the top of the inner side wall of the fixing portion 11 , and a second thermally conductive silicone rubber 211 for cooperating with the fixing port 111 is provided on the bottom of the plug-in portion 21 .

Figures 1 to 9 As shown, a first thermally conductive silicone 113 for heat conduction is provided on the top of the inner wall of the fixing portion 11. The first thermally conductive silicone 113 can cooperate with each other to conduct heat at the top of the fixing portion 11 and the plug-in portion 21, thereby ensuring that the heat on the plug-in portion 21 is smoothly transferred to the fixing portion 11, and then the heat is transferred to the base 1.

[0076] like Figures 1 to 9 As shown, the bottom of the plug-in portion 21 is provided with a second thermally conductive silicone 211 for cooperating with the fixing port 111. The second thermally conductive silicone 211 can conduct heat between the bottom of the plug-in portion 21 and the optoelectronic component 3, so that the heat of the optoelectronic component 3 can be smoothly transferred to the plug-in portion 21, and then the heat on the plug-in portion 21 can be smoothly transferred to the fixing portion 11, thereby ensuring the heat dissipation effect of the optical module housing.

[0077] The beneficial effect brought by the above implementation method is that the heat on the plug-in part is smoothly transferred to the fixing part through the first thermally conductive silicone, and then the heat is transferred to the base. Compared with the optical module housing with a snap-fit ​​structure, the heat conduction area is increased and the heat dissipation effect of the optical module housing is improved.

[0078] The beneficial effect brought about by the above implementation method is that the optoelectronic component can transfer heat to the plug-in board part through the second thermally conductive silicone, and then the heat on the plug-in board part can be smoothly transferred to the fixing part, further ensuring the heat dissipation effect of the optical module housing.

[0079] In some implementations, a bottom heat dissipation fin 14 is provided on a side of the bottom surface of the base 1 away from the optoelectronic component 3 , and a third thermally conductive silicone 141 for heat conduction is provided between the bottom surface of the base 1 and the optoelectronic component 3 .

[0080] like Figure 6 to Figure 7As shown, a bottom heat dissipation fin 14 is provided on the side of the bottom surface of the base 1 away from the optoelectronic component 3, and the bottom heat dissipation fin 14 is used to dissipate heat from the bottom of the base 1. A third thermally conductive silicone 141 for heat conduction is provided between the bottom surface of the base 1 and the optoelectronic component 3. Heat can be conducted between the bottom surface of the base 1 and the optoelectronic component 3 through the third thermally conductive silicone 141, thereby improving the thermal conductivity effect of the base 1 and the optoelectronic component 3.

[0081] Exemplarily, the bottom heat sink fins on the base may be integrally formed with the base.

[0082] The beneficial effect brought about by the above implementation method is that the bottom heat dissipation fins are used to dissipate heat from the bottom of the base, and the third thermally conductive silicone can conduct heat between the bottom surface of the base and the optoelectronic component, thereby improving the heat dissipation effect of the base on the optoelectronic component.

[0083] The beneficial effect brought about by the above implementation method is that the bottom heat dissipation fins on the base are integrally formed with the base, which can transfer the heat on the fixed part to the base, thereby improving the overall heat dissipation effect of the base.

[0084] In some implementations, a gap is provided between the end of the bottom heat dissipation fin 14 and the card slot 131 , and the length of the gap is 5 mm to 10 mm.

[0085] like Figure 7 As shown, a gap L is provided between the end of the bottom heat dissipation fin 14 and the card slot 131 , and the length of the gap L is 5 mm to 10 mm, so that there is no interference between the bottom heat dissipation fin 14 and the card slot 131 , thereby ensuring the convenience of the cover installation and the heat dissipation effect of the base 1 .

[0086] The beneficial effect brought about by the above implementation method is that there will be no interference between the bottom heat dissipation fins and the card slots, which ensures the convenience of installing the cover body and at the same time can ensure the heat dissipation effect of the base.

[0087] In some implementations, a top heat dissipation fin 25 is provided on the top of the cover body 2. The top heat dissipation fin 25 extends from the plug-in portion 21 to the plug-in portion 23. A yielding portion forming a step structure is provided at one end of the top heat dissipation fin 25 located at the plug-in portion 21.

[0088] like Figure 7 and Figure 8 As shown, a top heat dissipation fin 25 is provided on the top of the cover body 2, that is, the cover body 2 has serrated heat dissipation fins on the top of the plug-in portion 21 and the plug-in portion 23. The top heat dissipation fin 25 can dissipate heat from the top of the cover body 2, further improving the heat dissipation effect of the optical module housing.

[0089] like Figure 7As shown, the top heat dissipation fins 25 extend from the plug-in plate portion 21 to the plug-in portion 23 , so that the top heat dissipation fins 25 can extend from the plug-in plate portion 21 to the plug-in portion 23 to dissipate heat for the cover 2 efficiently.

[0090] Structurally, the top heat dissipation fin 25 is provided with a step-shaped concession portion 251 at one end of the plug-in plate portion 21 , through which the concession portion 251 can make way for the fixing portion 11 , thereby ensuring the flatness of the top heat dissipation fin 25 when assembled on the fixing portion 11 .

[0091] The beneficial effect brought about by the above implementation method is that the fixing part can be given way by the giving way part, thereby ensuring the flatness of the top heat dissipation fins assembled on the fixing part.

[0092] An embodiment of the present application also provides a 5G optical module, including any of the above-mentioned 5G optical module housing structures, and also including a pull ring, which is connected to one end of the base 1 where the bayonet portion 13 is located.

[0093] The beneficial effect brought about by the above implementation method is that the base can be pulled by the pull ring to pull the optical module, and a complete external shell structure of the optical module is formed circumferentially at the fixing part of the optical module, which can ensure the structural stability of the optical module when removing the optical module from the switch.

[0094] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
