Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical communication technology, and in particular to an optical module mounting structure, an optical module, and an optical communication module. Background Technology
[0002] With the rapid growth in bandwidth demands from end customers, optical communication technology is widely used in the communications field. Optical modules are a crucial component in optical communication. As the transmission bandwidth capacity of optical modules gradually increases, their power consumption also rises, making heat dissipation a prominent issue for optical communication equipment. Furthermore, optical modules require cages to be mounted on the single-board system of communication products, and these cages completely enclose the optical modules, hindering heat dissipation. Utility Model Content
[0003] The main purpose of this utility model is to propose an optical module installation structure, an optical module, and an optical communication module, aiming to provide a cage structure that is compatible with a variety of optical modules.
[0004] To achieve the above objectives, this utility model proposes an optical module mounting structure, wherein the optical module mounting structure includes:
[0005] The main body has an insertion end at one end in a first direction and a clearance side at one end in a second direction. A mounting cavity is formed within the main body, penetrating the insertion end. A clearance hole is provided on the clearance side of the main body, communicating with the mounting cavity. A clearance channel is formed on the clearance side of the main body between the insertion end and the clearance hole.
[0006] The limiting component includes a limiting member movably disposed at the clearance hole, the limiting member having multiple limiting positions in its active stroke, and being able to limit various optical modules in the multiple limiting positions;
[0007] The body has an outwardly protruding side between the clearance hole and the insertion end to form an arched portion. The inner side of the arched portion defines the clearance channel. The limiting member is movably installed on the arched portion. The arched portion has a reserved area on the third-direction upward side. An elastic member connecting the arched portion and the limiting member is provided in the reserved area. The elastic member is used to reset the limiting member towards the clearance hole.
[0008] In this invention, the installation structure of the optical module is adjusted to address the heat dissipation problem. Existing heat dissipation solutions involve opening a hole in the cage and attaching a heat sink to the optical module to transfer heat from the module to the outside of the cage. However, this method results in a long heat dissipation path and limited cooling capacity, failing to meet the cooling requirements of increased power consumption. This invention adds a heat dissipation structure to the optical module. Compared to existing external, separate heat sinks, this integrated design offers better heat dissipation performance, and the heat dissipation path can be controlled through the specific design of the structure to improve heat dissipation performance and meet the cooling requirements of increased power consumption. Based on this, the cage structure needs to be adapted, that is, the optical module mounting structure needs to be adapted. Specifically, the main body of the optical module mounting structure proposed in this application is set as a clearance side on one side in the second direction, and the clearance side is provided with the clearance hole and the clearance channel. The clearance channel is located inside the arched part protruding on the main body. In this way, during the process of inserting the optical module into the main body, the heat dissipation structure on the optical module can move into the clearance hole through the clearance channel to complete the insertion action of the optical module. In addition, a reserved area is formed on one side of the arched part, and the main body forms a limiting step corresponding to the position of the reserved area, which can be used to guide conventional optical modules, has applicability, and meets EMC requirements. Furthermore, the main body is also provided with the limiting member, and the reserved area is provided with an elastic member connecting the arched part and the limiting member, so that the limiting member is used to limit the optical module on the avoidance side. In this way, when the avoidance hole and the avoidance channel are opened on the avoidance side, affecting the limiting and contact shielding of the optical module by the optical module mounting structure, the limiting member is driven by the elastic member to abut and limit the optical module on the one hand, and contacts the optical module on the other hand to realize the overlapping shielding of the optical module by the optical module mounting structure on all four sides of the optical module, thus solving the above problems and meeting the functional requirements.

[0024] With the rapid growth in bandwidth demands from end customers, optical communication technology is widely used in the communications field. Optical modules are a crucial component in optical communication. As the transmission bandwidth capacity of optical modules gradually increases, their power consumption also rises, making heat dissipation a prominent issue for optical communication equipment. Furthermore, optical modules require cages to be mounted on the single-board system of communication products, and these cages completely enclose the optical modules, hindering heat dissipation.
[0025] In view of this, this utility model proposes an optical module mounting structure, please refer to... Figures 1 to 5 This is an embodiment of the optical module mounting structure proposed in this application. The optical module mounting structure will be described in detail below with reference to the specific drawings.
[0026] Please see Figures 1 to 2The optical module mounting structure 100 includes a main body 1 and a limiting component 2. One end of the main body 1 in a first direction is an insertion end 1a, and the other end in a second direction is a clearance side 1b. A mounting cavity 11 is formed within the main body 1, penetrating the insertion end 1a. A clearance hole 12 communicating with the mounting cavity 11 is provided on the clearance side 1b of the main body 1. A clearance channel 13 is formed between the insertion end 1a and the clearance hole 12 on the clearance side 1b of the main body 1. The limiting component 2 includes a limiting member 21 movably disposed at the clearance hole 12. The limiting member 21 has multiple limiting members along its travel. The device is positioned such that it can limit the position of various optical modules 200 in multiple limiting positions. The body 1 has an outward protrusion on the clearance side 1b between the clearance hole 12 and the insertion end 1a, forming an arched portion 14. The inner side of the arched portion 14 defines the clearance channel 13. The limiting member 21 is movably installed on the arched portion 14. The arched portion 14 has a reserved area on the third-party upward side. An elastic member 3 is provided in the reserved area to connect the arched portion 14 and the limiting member 21. The elastic member 3 is used to reset the limiting member 21 towards the clearance hole 12.
[0027] In this invention, the optical module mounting structure 100 is adjusted to address the heat dissipation problem of the optical module 200. Existing heat dissipation solutions involve opening a hole in the cage and attaching a heat sink to the optical module 200 to transfer heat from the optical module 200 to the outside of the cage. However, this method results in a long heat dissipation path and limited heat dissipation capacity, failing to meet the cooling requirements of increased power consumption. In this invention, a heat dissipation structure 202 is added to the optical module 200. Compared to existing external, separate heat sinks, this integrated design offers better heat dissipation performance, and the heat dissipation path can be controlled through the specific design of the heat dissipation structure 202 to improve heat dissipation performance and meet the cooling requirements of increased power consumption. Based on this, the cage structure needs to be adapted, that is, the optical module mounting structure 100 needs to be adapted. Specifically, the main body 1 of the optical module mounting structure 100 proposed in this application is set as a clearance side 1b on one side in the second direction, and the clearance side 1b is provided with the clearance hole 12 and the clearance channel 13. The clearance channel 13 is located inside the arched part 14 protruding on the main body 1. In this way, during the process of inserting the optical module 200 into the main body 1, the heat dissipation structure 202 on the optical module 200 can move into the clearance hole 12 through the clearance channel 13 to complete the insertion action of the optical module 200. In addition, a reserved area is formed on one side of the arched part 14, and the main body 1 forms a limiting step corresponding to the position of the reserved area, which can be used to guide conventional optical modules, has applicability, and meets EMC requirements. Furthermore, the main body 1 is also provided with the limiting member 21, and the reserved area is provided with an elastic member 3 connecting the arched part 14 and the limiting member 21, so that the limiting member 21 is used to limit the optical module 200 on the avoidance side 1b. In this way, when the avoidance hole 12 and the avoidance channel 13 are opened on the avoidance side 1b, affecting the limiting and contact shielding of the optical module 200 by the optical module mounting structure 100, the limiting member 21 is driven by the elastic member 3 to abut and limit the optical module 200, and on the other hand, it contacts the optical module 200 to realize the overlapping shielding of the optical module 200 by the optical module mounting structure 100 around the optical module 200, thus solving the above problems and meeting the functional requirements.
[0028] It is understood that the limiting member 21 is driven by the elastic member 3, so that the limiting member 21 can be flexibly and movable. On the one hand, it can move to avoid the optical module 200 when the optical module 200 is inserted into the main body 1. On the other hand, after the optical module 200 is inserted, the limiting member 21 is driven by the elastic member 3 to press against the optical module 200, thereby limiting the contact of the optical module 200. In this way, the movable limiting member 21 can also be applied to optical modules 200 of different sizes, that is, at least to the optical module 200 with heat dissipation structure 202 in this application and conventional optical modules, thus meeting the applicability requirements. Regarding the movement mode of the limiting member 21, it can be configured to slide along the second direction, or it can be configured to rotate along the third direction axial direction. In this embodiment, the limiting member 21 is rotatably disposed on the arched portion 14. The limiting member 21 has multiple limiting positions along its rotation stroke, so that different sizes of optical modules 200 can be used at different limiting positions to meet applicability requirements. Moreover, the rotatably disposed limiting member 21 is more convenient to be pushed and rotated by the optical module 200 when the optical module 200 is inserted, reducing the resistance when the optical module 200 is placed into the main body 1 and simplifying the operation of placing the optical module 200 into the main body 1.
[0029] Further, please refer to Figure 2 and Figure 3 The installation position of the limiting member 21 on the arched portion 14 is not limited, as long as it can achieve the above-mentioned rotation adjustment setting and abut against and limit the optical module 200. In this embodiment, the limiting member 21 is rotatably installed on the end of the arched portion 14 near the clearance hole 12. On the one hand, installing the limiting member 21 at the end of the arched portion 14 facilitates the installation of the limiting member 21. On the other hand, setting the limiting member 21 at the end near the clearance hole 12 makes it so that when the optical module 200 is inserted into the main body 1, it pushes and drives the free end of the limiting member 21 away from the arched portion 14 without being restricted by the structure of the arched portion 14, which facilitates the structural setting of the arched portion 14 and the limiting member 21.
[0030] Furthermore, based on the structure where the limiting member 21 is rotatably mounted on one end of the arched portion 14 near the clearance hole 12, one end of the limiting member 21 in the first direction is rotatably mounted on the arched portion 14, and the other end is an abutment end 211 used to press against the optical module 200. By rotatably mounting one end of the limiting member 21 on the arched portion 14, the structure of the limiting member 21 itself will not interfere with the arched portion 14 during its rotation, thereby simplifying the relative structural arrangement of the arched portion 14 and the limiting member 21. At this time, the elastic member 3 can be a torsion spring disposed at the connection between the limiting member 21 and the arched portion 14, but obviously the torsion spring structure is not convenient for installation and disassembly. In this embodiment, the elastic member 3 is set at the connection between the arched portion 14 and the limiting member 21. The tension spring on the side of the third direction pulls the arched part 14 and the limiting member 21 to limit the limiting member 21 to be close to the main body 1. This satisfies the requirement that when the optical module 200 is subsequently placed into the main body 1, the optical module 200 pushes against the limiting member 21 to overcome the elastic force of the elastic member 3 and rotate. This allows the abutting end 211 of the limiting member 21 to be pulled and held by the elastic member 3 to limit the optical module 200. Specifically, the abutting end 211 is arc-shaped so that when the position of the abutting end 211 relative to the optical module 200 changes, that is, when the abutting point of the abutting end 211 and the optical module 200 changes, the abutting end 211 can smoothly transition without causing resistance. Moreover, the arc-shaped surface abuts against the optical module 200, which can play a certain protective role.
[0031] Specifically, please refer to Figure 2 and Figure 5 The limiting member 21 that satisfies the above functions can be a rod-shaped structure or a plate-shaped structure. In this embodiment, the limiting member 21 is set as a cover plate, which has strong stability. However, the cover plate will partially cover the avoidance channel 13, affecting the airflow in the avoidance channel 13 and thus affecting the heat dissipation effect of the optical module 200. Therefore, in this embodiment, a ventilation hole 212 is also provided on the cover plate to improve the above heat dissipation problem.
[0032] Please see Figure 6This utility model also proposes an optical module 200 for mounting on the aforementioned optical module mounting structure 100. The optical module 200 includes a body 201 and a heat dissipation structure 202. The body 201 extends along a first direction and is inserted into a mounting cavity 11 on the optical module mounting structure 100. The heat dissipation structure 202 is mounted on one side of the body 201 in a second direction, and is mounted to the clearance hole 12 via the clearance channel 13. Compared to a separate heat sink, the heat dissipation structure 202, when integrated into the body 201, offers better heat dissipation performance. Furthermore, the heat dissipation path can be controlled through the specific configuration of the heat dissipation structure 202, eliminating concerns about the connection and thermal conductivity between the heat dissipation structure 202 and the body 201. This improves heat dissipation performance and meets the cooling requirements of increasing power consumption.
[0033] Specifically, the heat dissipation structure 202 can have superior heat absorption performance to conduct heat away from the body 201 of the optical module 200, thereby achieving heat dissipation and cooling of the body 201. In addition, the heat dissipation structure 202 can also have superior heat dissipation performance, so that after conducting heat away from the body 201 of the optical module 200, it can quickly dissipate the heat to the environment. The specific structural settings are mainly based on functional requirements, and can meet the required heat dissipation performance improvement. In this embodiment, the heat dissipation structure 202 includes multiple heat dissipation ribs 2021, which extend along a first direction and are spaced apart in a third direction. This increases the heat dissipation area through the heat dissipation ribs 2021, thereby improving the heat dissipation performance of the heat dissipation structure 202. At the same time, the spaced heat dissipation ribs 2021 define an air outlet channel, guiding the airflow in the first direction to flow within the channel, which can also accelerate the dissipation of heat from the heat dissipation ribs 2021, meeting the requirements for improved heat dissipation performance.
[0034] Furthermore, the heat dissipation ribs 2021 extending along the first direction block the airflow from the third upward direction. To utilize the airflow from the third upward direction to further improve the heat dissipation performance of the heat dissipation structure 202, in this embodiment, at least one heat dissipation rib 2021 has a through hole 2022 to connect the air ducts spaced apart in the third upward direction, so that the airflow in the third upward direction can flow in at least two air ducts, thereby increasing the heat dissipation contact area between the airflow and the heat dissipation rib 2021 and improving the heat dissipation effect. At the same time, if multiple heat dissipation ribs 2021 have the through hole 2022, and the heat dissipation rib 2021 located at the edge of the third upward direction has the through hole 2022, the airflow flowing along the third direction outside the heat dissipation structure 202 can be introduced into the air duct extending along the first direction defined by the adjacent heat dissipation ribs 2021, further improving the heat dissipation effect of the heat dissipation structure 202 and meeting the functional requirements.
[0035] Furthermore, the provision of the heat dissipation rib 2021 to increase the heat dissipation area has been described above. In this embodiment, at least one end of the heat dissipation rib 2021 extends beyond the body 201 in the first direction to extend the size of the heat dissipation rib 2021 relative to the body 201, thereby further increasing the heat dissipation area of the heat dissipation rib 2021 and improving heat dissipation performance.
[0036] Please see Figure 7 and Figure 8 This utility model also proposes an optical communication module 1000, wherein the optical communication module 1000 includes an optical module mounting structure 100 and an optical module 200. The specific structure of the optical module mounting structure 100 is as described in the above embodiments. Since the optical communication module 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The optical module mounting structure 100 is used to fix it on the single board system of the communication product; the optical module 200 is inserted into the mounting cavity 11 of the optical module mounting structure 100 and is limited by the limiting member 21.
[0037] Specifically, please refer to Figure 7 In one embodiment of the optical communication module 1000, the specific structure of the optical module 200 refers to the above embodiments. Since the optical communication module 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The optical module mounting structure 100 is applicable to conventional optical modules and the optical module 200 proposed in this application. Therefore, in another embodiment of the optical communication module 1000, please refer to... Figure 8A conventional optical module is inserted into the optical module mounting structure 100. In other embodiments of the optical communication module 1000, other optical module 200 structures of different sizes can also be inserted to meet the above functional requirements.
