Description

Technical Field

[0001] This application relates to the field of optical communication technology, and more specifically, to an optical module component and a data center device. Background Technology

[0002] Optical modules typically refer to integrated modules used for photoelectric conversion, which can convert optical signals into electrical signals or vice versa, playing an important role in the field of optical data centers.

[0003] Data center infrastructure construction uses a large number of optical modules, but the data center environment cannot be completely dust-free. During the installation and removal of optical modules, dust can easily enter the optical modules, reducing the stability and reliability of data transmission. Summary of the Invention

[0004] This application provides an optical module component and a data center device that can minimize the entry of dust into the optical module.

[0005] In a first aspect, this application provides an optical module assembly, comprising:

[0006] An optical module, including a housing having an optical port;

[0007] A dust cover, rotatably connected to the housing, is used to close or open the optical port; and

[0008] A push-pull component is movably connected to the optical module along a first direction, the first direction being perpendicular to the plane where the optical port is located;

[0009] The optical module assembly has a normal state and an installed state. In the normal state, the dust cover closes the optical port. In the installed state, the dust cover opens the optical port. When the optical module assembly switches from the normal state to the installed state, the push-pull member is connected to the dust cover, the push-pull member moves along the first direction, and drives the dust cover to rotate to the side away from the optical port, so as to open the optical port.

[0010] Optionally, the optical module assembly further includes a pre-tightening member, which connects the dust cover and the optical module, and is used to apply a pre-tightening force to the dust cover toward the optical port.

[0011] Optionally, the dust cover is rotatably connected to the housing via a rotating shaft, the pretensioning component includes a torsion spring, the torsion spring is sleeved on the rotating shaft, and the torsion spring includes at least two force-applying arms. The dust cover and the optical module are connected to different force-applying arms and receive pretensioning forces in different directions.

[0012] In the normal state, the torsion spring of the optical module assembly has a first preload, and when the optical module assembly switches from the normal state to the installation state, the torsion spring has a second preload, wherein the first preload is less than the second preload.

[0013] Optionally, the torsion spring is a double torsion spring, including a first force-applying arm, a second force-applying arm, and a third force-applying arm, wherein the third force-applying arm is located between the first force-applying arm and the second force-applying arm; wherein the first force-applying arm and the second force-applying arm are both connected to the dust cover, and the third force-applying arm is connected to the optical module.

[0014] Optionally, the dust cover is provided with a connecting groove, and the first force-applying arm and the second force-applying arm are inserted into the connecting groove.

[0015] Optionally, the dust cover is rotatably connected to the housing via a rotating shaft. The dust cover includes a connecting end and a free end. The connecting end is sleeved on the rotating shaft, which is located at the edge of the optical port and is fixed to the optical module.

[0016] When the optical module assembly switches from the normal state to the installation state, the free end rotates around the axis of rotation to the side opposite to the optical port.

[0017] Optionally, the connecting end includes a protrusion located on the side of the rotating shaft away from the free end, and the push-pull member is provided with a push-pull portion;

[0018] When the optical module assembly switches from the normal state to the installation state, the push-pull part abuts against the protrusion, and the push-pull part applies a force along the first direction to the protrusion, so as to drive the free end of the dust cover to rotate away from the optical port.

[0019] Optionally, there are two push-pull portions and two protrusions, with each pair corresponding to the other.

[0020] The two protrusions are spaced apart along the axial direction of the rotating shaft, and the dust cover has a notch located between the two push-pull parts.

[0021] Optionally, the housing includes a plug-in terminal for plugging into a network device. The plug-in terminal and the optical port are located at opposite ends of the housing. The first direction includes a first sub-direction and a second sub-direction pointing in opposite directions. The direction from the optical port to the plug-in terminal is the first sub-direction, and the direction from the plug-in terminal to the optical port is the second sub-direction.

[0022] When the optical module assembly switches from the normal state to the installation state, the push-pull member moves along the first sub-direction.

[0023] Optionally, the optical module assembly further includes a locking member for being movably connected to the optical module along a first direction;

[0024] In the installed state, the locking member is used to lock the optical module assembly; the optical module assembly also has an unlocked state, in which the locking member is used to unlock the optical module, and the dust cover closes the optical port; when the optical module assembly switches from the installed state to the unlocked state, the push-pull member is connected to the locking member, the push-pull member moves along a second sub-direction, driving the locking member to move along the second sub-direction to unlock the optical module.

[0025] Optionally, the locking member is fixedly connected to the push-pull member; or,

[0026] In the normal and installed states, the push-pull member of the optical module assembly is separated from the locking member. When the optical module assembly switches from the installed state to the unlocked state, the push-pull member abuts against the locking member and applies a force toward the locking member in the second sub-direction.

[0027] Optionally, the optical module assembly further includes a first reset member disposed between the locking member and the optical module;

[0028] In the normal state, the first reset member of the optical module assembly is in a natural state; when the optical module assembly is in the unlocked state, the first reset member is used to apply a restoring force along a first sub-direction to the locking member.

[0029] Optionally, the first reset element is a first reset spring;

[0030] In the normal state, the first reset spring of the optical module assembly is in a natural state; when the optical module assembly is in the unlocked state, the first reset spring is in a compressed state.

[0031] Secondly, this application provides a data center device, comprising:

[0032] A network device having a port; and an optical module assembly as described in any of the preceding claims, the optical module being connected to the port.

[0033] The optical module components and data center equipment provided in this application have at least the following advantages:

[0034] A rotating dust cover is installed at the optical port of the optical module. In its normal state, when the optical module is not connected to network equipment, the dust cover seals the optical port, forming a physical barrier that effectively prevents dust and other foreign objects from entering the optical module, providing good dust protection when the optical module is not in operation. When it is necessary to install the optical module into the network equipment (i.e., when the optical module is switched from its normal state to the installation state), the user can move the push-pull component in the first direction, causing the dust cover to rotate to the side away from the optical port, thereby opening the optical port. During this process, the user does not need to manually operate the dust cover, avoiding the introduction of dust that might occur if the user manually opened the dust cover.

[0042] The technical solutions in the embodiments (or "implementations") of this disclosure will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

Furthermore, terms such as "first" and "second" in this disclosure are used only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0044] This application provides an optical module component and a data center device, which will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0045] Please refer to Figures 1 to 5 This application provides an optical module component and a data center device. The data center device includes a network device (not shown) and the optical module component. The network device may be, but is not limited to, a switch, a server, a router, etc.

[0046] The aforementioned optical module assembly may include an optical module 10, a dust cover 20, and a push-pull component 30.

[0047] The main function of the optical module 10 is to realize photoelectric conversion in the optical communication process, thereby supporting high-speed and long-distance data transmission through the optical fiber 80. The optical module 10 may include a housing 11 and an optoelectronic device 12. The housing 11 has an optical port 111 and a receiving space, which can accommodate and protect the optoelectronic device 12. The optical fiber 80 and the like can establish a connection with the optoelectronic device 12 in the receiving space through the optical port 111. Network devices may be provided with ports, and the optical module 10 is connected to the ports so that the network devices can connect to the transmission medium such as the optical fiber 80 through the optical module 10.

[0048] The aforementioned optoelectronic device 12 may include an optical interface, an optical transmitter, an optical receiver, and functional circuitry. The optical interface is used to transmit and receive optical signals, the optical transmitter is used to convert electrical signals into optical signals, the optical receiver is used to convert optical signals into electrical signals, and the functional circuitry is used to process the electrical signals. In some embodiments, the functional circuitry may be a chip, an integrated circuit, or a printed circuit board, but is not limited thereto.

[0049] Please refer to Figure 2The housing 11 of the optical module 10 includes an upper cover 112 and a base 113, which are fastened together to form a receiving space for accommodating the optoelectronic device 12. The connection between the upper cover 112 and the base 113 includes, but is not limited to, bolt connection, screw connection or snap-fit ​​connection.

[0050] It should be noted that the housing 11 of the optical module 10 can also have other shapes and structures, and the housing 11 can also include more parts. For example, the housing 11 can include a top cover 112, a base 113, and side plates. The top cover 112 is connected to the base 113 through the side plates, but is not limited thereto.

[0051] The dust cover 20 is rotatably connected to the housing 11, allowing the optical port 111 to be opened or closed. The push-pull component 30 is movably connected to the optical module 10 along a first direction, allowing the user to perform operations such as taking, placing, pushing, and pulling the optical module 10, facilitating its installation in or removal from the network device. The push-pull component 30 is also connected to the dust cover 20, with connection methods including but not limited to abutment. The first direction is perpendicular to the plane containing the optical port 111.

[0052] Please refer to Figure 3 , Figure 4 and Figure 5 The optical module assembly has a normal state and an installed state. In the normal state, the dust cover 20 closes the optical port 111. In the installed state, the dust cover 20 opens the optical port 111. When the optical module assembly switches from the normal state to the installed state, the push-pull member 30 is connected to the dust cover 20, the push-pull member 30 moves in a first direction, and drives the dust cover 20 to rotate away from the optical port 111, thereby opening the optical port 111.

[0053] The aforementioned "normal state" refers to the default state when the optical module 10 is not connected to the network device. The "installation state" refers to the state when the fiber optic cable 80 is inserted into the optical port 111, and the optical module 10 is inserted into the network device and the connection is completed.

[0054] As described above, a rotatable dust cover 20 is installed at the optical port 111 of the optical module 10. When the optical module assembly is in its normal state, i.e., when the optical module 10 is not connected to the network device, the dust cover 20 closes the optical port 111, forming a physical barrier that effectively prevents dust and other foreign objects from entering the interior of the optical module 10, providing good dust protection when the optical module 10 is not in operation. When it is necessary to install the optical module 10 onto the network device (i.e., when the optical module assembly switches from its normal state to the installation state), the user can move the push-pull component 30 in the first direction, causing the dust cover 20 to rotate away from the optical port 111, thereby opening the optical port 111. During this process, the user does not need to manually operate the dust cover 20, avoiding the dust that might be introduced when the user manually opens the dust cover 20.

[0055] In one embodiment, the dust cover 20 is rotatably connected to the housing 11 via a pivot 40, and can rotate around the pivot 40 to close or open the optical port 111. Specifically, the dust cover 20 includes a connecting end 22 and a free end 21. The connecting end 22 is fitted onto the pivot 40, which is located at the edge of the optical port 111 and is fixed to the optical module 10. When the optical module 10 switches from its normal state to its installed state, the free end 21 rotates around the pivot 40 to the side away from the optical port 111.

[0056] The use of a pivot 40 for connection makes the connection structure between the dust cover 20 and the optical port 111 relatively simple, reducing manufacturing and installation difficulties. Furthermore, the pivot 40 is positioned at the edge of the optical port 111, allowing the dust cover 20 to fit snugly against the port, thus better sealing it and improving dust protection.

[0057] Furthermore, the two opposite ends of the rotating shaft 40 can be fixed to the upper cover 112 of the optical module 10 and located above the optical port 111. In this way, the free end 21 of the dust cover 20 can rotate from bottom to top, making it convenient for the user to insert the optical fiber 80 into the optical port 111 from below the rotating shaft 40.

[0058] Furthermore, the maximum opening angle of the dust cover 20 can be 70° to 90°, that is, when the optical module assembly switches from the normal state to the installed state, the maximum rotation angle of the free end 21 of the dust cover 20 is 70° to 90°. This allows the optical port 111 to be fully opened, facilitating the insertion of the optical fiber 80.

[0059] For example, the maximum opening angle of the dust cover 20 can be 70°, 75°, 80°, 85° or 90°, but is not limited thereto.

[0060] In one embodiment, the connecting end 22 of the dust cover 20 includes a protrusion 221 located on the side of the rotating shaft 40 away from the free end 21, i.e., the protrusion 221 extends beyond the rotating shaft 40 in the direction from the free end 21 to the connecting end 22. The push-pull member 30 is provided with a push-pull portion 31. When the optical module assembly switches from the normal state to the installed state, the push-pull portion 31 abuts against the protrusion 221, and the push-pull portion 31 applies a force along a first direction to the protrusion 221 to drive the free end 21 of the dust cover 20 to rotate away from the optical port 111.

[0061] Since the push-pull part 31 directly abuts against the protrusion 221 of the connection end 22 of the dust cover 20, the force of the push-pull part 30 can be directly and efficiently transmitted to the dust cover 20 without the need for an intermediate transmission component, causing the dust cover 20 to rotate and open the light port 111. In addition, the design of the protrusion 221 also helps to save space.

[0062] Furthermore, there are two push-pull portions 31 and two protrusions 221, with each pair corresponding to one another; wherein, the two protrusions 221 are distributed at intervals along the axial direction of the rotating shaft 40, and the dust cover 20 is provided with a notch 24, which is located between the two push-pull portions 31.

[0063] This design uses two push-pull parts 31 to apply force to the two protrusions 221 respectively, which can minimize the risk of the dust cover 20 tilting or jamming due to uneven force, allowing the dust cover 20 to rotate around the pivot 40 more smoothly and stably. Furthermore, the dust cover 20 has a notch 24 between the two push-pull parts 31, which reduces the overall weight of the dust cover 20, making it easier to rotate and reducing the difficulty and burden on the user.

[0064] Furthermore, the two protrusions 221 can also be symmetrical about the center of the notch 24 to make the entire dust cover 20 more balanced in terms of force.

[0065] In such Figures 1 to 4 In the embodiment shown, the push-pull member 30 is a push-pull ring with a ring-shaped structure, including two opposing sides, namely a first side 32 and a second side 33. One of the two push-pull parts 31 is connected to the first side 32 and extends toward the second side 33, while the other push-pull part 31 is connected to the second side 33 and extends toward the first side 32. That is, the extension directions of the two push-pull parts 31 are close to each other.

[0066] In one embodiment, the optical module assembly further includes a pretensioner connecting the dust cover 20 and the optical module 10, for applying a pretensioning force to the dust cover 20 toward closing the optical port 111.

[0067] The pre-tightening component applies a pre-tightening force to the dust cover 20, causing it to close towards the optical port 111. This ensures that the dust cover 20 fits more tightly against the optical port 111 under normal conditions, effectively preventing dust, impurities, and other foreign objects from entering the optical module 10. Even under slight vibration or external interference, the dust cover 20 maintains a good seal, better protecting the optoelectronic devices 12 inside the optical module 10 and ensuring the stability and reliability of data transmission. Furthermore, when the optical module 10 is switched from its installed state (i.e., removed from the network device), the pre-tightening force of the pre-tightening component causes the dust cover 20 to automatically and quickly reset and close the optical port 111. This timely closing of the dust cover 20, without the need for additional driving devices or complex operations, reduces the time window for dust to enter the optical port 111, further improving dustproof performance.

[0068] The aforementioned preload can be an elastic sheet, a compression spring, a torsion spring 50, or a magnetic attraction device, but is not limited to these.

[0069] In one embodiment, the preload element includes a torsion spring 50, which is sleeved on the rotating shaft 40. The torsion spring 50 includes at least two force-applying arms, with the dust cover 20 and the optical module 10 connected to different force-applying arms and receiving preload forces from different directions. In other words, by being sleeved on the rotating shaft 40, the torsion spring 50 applies forces in different directions to the dust cover 20 and the optical module 10 respectively, thereby achieving a preload effect on the dust cover 20. Under normal conditions, the torsion spring 50 has a first preload force, and when the optical module 10 switches from the normal state to the installation state, the torsion spring 50 has a second preload force, where the first preload force is less than the second preload force.

[0070] Thus, under normal conditions, the initial preload provided by the torsion spring 50 is relatively small, which allows the dust cover 20 to remain closed with low energy consumption, ensuring dust protection while avoiding excessive stress that could lead to material fatigue. When the optical module is installed, the optical fiber 80 is inserted into the optical port 111, preventing the dust cover 20 from closing towards the port. When the optical fiber 80 is removed from the port 111, the larger second preload force allows the dust cover 20 to quickly return to its closed state, promptly sealing the optical port 111 and preventing dust and other foreign objects from entering the optical module 10.

[0071] In one specific embodiment, the torsion spring 50 is a double torsion spring 50, including a first force-applying arm 51, a second force-applying arm 52 and a third force-applying arm 53, with the third force-applying arm 53 located between the first force-applying arm 51 and the second force-applying arm 52; wherein, the first force-applying arm 51 and the second force-applying arm 52 are both connected to the dust cover 20, and the third force-applying arm 53 is connected to the optical module 10.

[0072] The first force-applying arm 51 and the second force-applying arm 52 are connected to the dust cover 20 at the same time, which can apply force to the dust cover 20 evenly from two different positions. Compared with applying force from only one end, the dust cover 20 can more stably close the light opening 111 under normal conditions, avoiding the situation of tilting or incomplete closure due to uneven force, thus improving the dustproof effect.

[0073] Furthermore, the dust cover 20 is provided with a connecting groove 23, in which the first force-applying arm 51 and the second force-applying arm 52 are inserted. Thus, the connecting groove 23 provides a stable fixing position for the force-applying arms of the torsion spring 50, effectively preventing displacement or detachment of the force-applying arms from the dust cover 20 due to external forces during the insertion and removal of the optical module 10. Moreover, the connecting groove 23 can contact the first force-applying arm 51 and the second force-applying arm 52 in multiple directions, resulting in a large contact area and a more secure connection between the torsion spring 50 and the dust cover 20.

[0074] In one embodiment, the housing 11 includes a connector 114 for plugging into a network device, the connector 114 and the optical port 111 being located at opposite ends of the housing 11. A first direction includes a first sub-direction and a second sub-direction pointing in opposite directions; the direction from the optical port 111 to the connector 114 is the first sub-direction, and the direction from the connector 114 to the optical port 111 is the second sub-direction. When the optical module assembly switches from its normal state to its installed state, the push-pull member 30 moves along the first sub-direction.

[0075] With this setup, the direction in which the user operates the push-pull component 30 to open the dust cover 20 is consistent with the direction in which the optical module 10 is inserted into the network device. This conforms to conventional operating habits, reduces the complexity of operation, improves installation efficiency, and facilitates the rapid deployment of the optical module 10.

[0076] In one embodiment, the dust cover 20 further includes a limiting portion 25 located between the connecting end 22 and the free end 21. When the optical module assembly is installed, one end of the push-pull portion 31 along the second sub-direction also abuts against the limiting portion 25 of the dust cover 20.

[0077] Thus, when the user needs to remove the optical module 10 from the network device, the push-pull member 30 moves along the second sub-direction. At this time, since one end of the push-pull part 31 along the second sub-direction is still abutting against the limiting part 25 of the dust cover 20, the push-pull part 31 can apply a force along the second sub-direction to the limiting part 25 of the dust cover 20. This force can cause the free end 21 of the dust cover 20 to rotate in the direction toward the optical port 111, thereby making the dust cover 20 close faster. In other words, this solution realizes the linkage between the closing action of the dust cover 20 and the removal operation of the optical module 10, simplifying the operation process when the user removes the optical module 10 from the network device, eliminating the need for the user to manually close the dust cover 20, and improving operational portability.

[0078] In one embodiment, the optical module assembly further includes a locking member 60 for slidingly connecting to the optical module 10 along a first direction. The sliding connection can be a guide rail slider connection, a friction contact sliding connection, or is not limited to these methods.

[0079] In the installed state, the locking element 60 is used to lock the optical module 10. The optical module assembly also includes an unlocked state, in which the locking element 60 is used to unlock the optical module 10, and the dust cover 20 closes the optical port 111.

[0080] When the optical module assembly switches from the installed state to the unlocked state, the push-pull member 30 is connected to the locking member 60, and the push-pull member 30 moves along the second sub-direction, causing the locking member 60 to move along the second sub-direction to unlock the optical module 10.

[0081] By connecting the push-pull member 30 and the locking member 60, when it is necessary to switch the optical module assembly from the installed state to the unlocked state, simply operate the push-pull member 30 to move along the second sub-direction, which will drive the locking member 60 to move synchronously to unlock the optical module 10. The operation is simple and convenient, reduces complicated unlocking steps, and improves the insertion and removal efficiency of the optical module 10.

[0082] In summary, in the solution provided in this embodiment, under normal conditions, the dust cover 20 of the optical module assembly can seal the optical port 111, preventing dust from entering. When the optical module assembly switches from its normal state to its self-installation state, the user can push the push-pull component 30, causing it to move along the first sub-direction, opening the dust cover 20 while simultaneously plugging the optical module 10 into the network device. When the optical module assembly switches from its self-installation state to its unlocked state, the user can pull the push-pull component 30, causing it to move along the second sub-direction, which in turn moves the locking component 60 along the second sub-direction, thereby unlocking the optical module 10. By moving the same push-pull component 30 in different directions, the user achieves multiple key operations such as opening the dust cover 20, installing the optical module 10, and unlocking the optical module 10, demonstrating a high degree of integration.

[0083] It should be noted that when the optical module component is in the unlocked state, or when it switches from the installed state to the unlocked state, the user can manually close the dust cover 20, or the user can use the pre-tightening member, the limiting part 25, etc. described in the above embodiments to achieve automatic closing of the dust cover 20. This application does not impose any specific restrictions on this.

[0084] Furthermore, the method by which the locking member 60 locks or unlocks the optical module 10 can be found in related technologies. However, for ease of understanding, this application provides an example: the locking member 60 can be slidably connected to the outer wall of the base 113 of the housing 11. The locking member 60 has two latching portions 61. When the optical module assembly is in the installed state, the latching portions 61 are used to latch and engage with the latching engagement portion of the network device in a first direction, thereby locking the optical module 10. When the optical module assembly switches from the installed state to the unlocked state, the push-pull member 30 drives the locking member 60 to move in a second sub-direction, disengaging the latching portions 61 from the latching engagement portion of the network device, thereby unlocking the optical module 10.

[0085] In one embodiment, the locking member 60 is fixedly connected to the push-pull member 30, and the push-pull member 30 can be slidably connected to the optical module 10 through the locking member 60.

[0086] The aforementioned fixing connection method can be, but is not limited to, snap-fit, threaded connection, adhesive bonding, or integral molding. This fixing connection method makes the connection between the locking member 60 and the push-pull member 30 more stable, ensuring the consistency of their movements. When the push-pull member 30 moves, the locking member 60 can also move accordingly, realizing the locking or unlocking of the optical module 10, without any deviation in movement caused by loose connections or gaps.

[0087] It should be noted that the maximum travel of the locking member 60 along the first direction can be set as needed, and the optical module 10 can be equipped with corresponding limiting members so that the locking member 60 slides within a predetermined travel and drives the optical module 10 to move through the limiting members. This application does not impose specific restrictions on this.

[0088] For example, the end of the push-pull member 30 facing the locking member 60 is a semi-enclosed frame structure, and the end of the push-pull member 30 facing the locking member 60 is fitted onto the end of the locking member 60 and fixed by bolts or buckles.

[0089] In another embodiment, in the normal and installed states of the optical module assembly, the push-pull member 30 is separated from the locking member 60. When the optical module assembly switches from the installed state to the unlocked state, the push-pull member 30 abuts against the locking member 60, applying a force toward the locking member 60 in a second sub-direction.

[0090] In this way, the push-pull component 30 and the locking component 60 are separate in the normal and installed states, making the operation in these two states relatively independent. When installing the optical module 10, the user can push the optical module 10 using the push-pull component 30 and open the dust cover 20 to smoothly plug the optical module 10 into the network device. At this time, the locking component 60 will not interfere with the installation operation. When it is necessary to switch from the installed state to the unlocked state, the push-pull component 30 and the locking component 60 abut against each other and apply force, realizing the function switch. This design allows the push-pull component 30 and the locking component 60 to have a certain degree of structural independence, which facilitates their individual maintenance, replacement, or improvement.

[0091] Please refer to Figure 6 In one embodiment, the optical module assembly further includes a first reset member disposed between the locking member 60 and the optical module 10. When the optical module 10 is in its normal state, the first reset member is in a natural state; when the optical module assembly is in the unlocked state, the first reset member is used to apply a restoring force to the locking member 60 along a first sub-direction.

[0092] When the optical module assembly is in the unlocked state, the first reset component can apply a restoring force along the first sub-direction to the locking component 60, causing it to automatically return to its initial position (i.e., its normal position). This automatic reset function reduces the need for manual intervention, ensures that the locking component 60 can accurately return to its original position after each unlocking, and prepares for the next locking operation, thus improving the convenience of operating the optical module assembly.

[0093] The number of the first reset components can be two, and the first reset components can be springs, sheet metal, elastic rubber, or other structures, but are not limited to these.

[0094] Furthermore, the first reset element is a first reset spring 71; when the optical module assembly is in its normal state, the first reset spring 71 is in its natural state; when the optical module assembly is in its unlocked state, the first reset spring 71 is in its compressed state. That is, when the optical module assembly is unlocked, the first reset spring 71 is compressed to store elastic potential energy. When the unlocking action is completed, the first reset spring 71 releases its elastic potential energy, applying a restoring force along the first sub-direction to the locking element 60, so that the locking element 60 is accurately reset. The spring has a relatively simple structure and is easy to manufacture and install. Moreover, during the unlocking process, when the push-pull element 30 pushes the locking element 60 to compress the first reset spring 71, the first reset spring 71 can play a certain buffering role. At the same time, the user can feel the change in spring resistance in real time through touch, which provides clear feedback for operation and helps the user judge the progress of the unlocking operation.

[0095] Specifically, the side wall of the optical module 10 base 113 is provided with a first mounting groove, the first reset spring 71 is located in the mounting groove, the locking member 60 has a first abutting part 62 extending toward the first mounting groove, one end of the first reset spring 71 along the second sub-direction is fixed in the first mounting groove, and one end of the first reset spring 71 along the first sub-direction cooperates with the first abutting part 62.

[0096] Furthermore, the optical module assembly may also include a second reset member disposed between the locking member 60 and the optical module 10. When the optical module 10 is in its normal state, the first reset member is in its natural state. When the optical module assembly is in its installed state, the second reset member is used to apply a restoring force to the locking member 60 along a second sub-direction.

[0097] The number of the second reset components can also be two, and the second reset components can be springs, sheet metal, elastic rubber, or other similar structures, but are not limited to these.

[0098] Specifically, the second reset component is a second reset spring 72. A second mounting groove is provided on the outer wall of the optical module 10 base 113. The second reset spring 72 is disposed within the second mounting groove. The locking component 60 has a second abutment portion 63 extending toward the second mounting groove. One end of the second reset spring 72 along the first sub-direction is fixed inside the housing 11, and the other end along the second sub-direction abuts against the second abutment portion 63. When the optical module assembly is in its normal state, the second reset spring 72 is in its natural state. When the optical module assembly is in its installed state, the second reset spring 72 is in its stretched state. That is, when the optical module assembly switches from its normal state to its installed state, the second reset spring 72 is stretched and stores elastic potential energy. During the unlocking process of the locking component 60, the second reset spring 72 can provide a spring force that moves the locking component 60 along the second sub-direction, assisting the user in pulling the locking component 60 via the push-pull component 30. Meanwhile, since the push-pull member 30 is fixedly connected to the locking member 60, the second reset spring 72 also indirectly pushes the push-pull member 30 to move along the second sub-direction, so as to drive the free end 21 of the dust cover 20 to move towards the light port 111, so as to close the light port 111.

[0099] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
