[0044] The present application provides an optical module assembly and a data center equipment, which will be described in detail below with reference to the accompanying drawings. The features in the following embodiments and implementation manners can be combined with each other without conflict.

[0045] Please refer to Figures 1 to 5 The embodiments of the present application provide an optical module assembly and a data center equipment. The data center equipment includes a network device (not shown) and the optical module assembly. The network device can be, but is not limited to, a switch, a server, a router, etc.

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

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

[0048] The above-mentioned optoelectronic device 12 can include an optical interface, an optical transmitter, an optical receiver, and a functional circuit. Among them, the optical interface is used to send 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 circuit is used to process electrical signals. In some embodiments, the functional circuit can 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, and the upper cover 112 and the base 113 are buckled to form a containing space for accommodating the optoelectronic device 12. The connection manner of the upper cover 112 and the base 113 includes but is not limited to bolt connection, screw connection or clamping.

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

[0051] The dust cover 20 is rotationally connected to the housing 11 and can open or close the optical port 111. The push-pull piece 30 is movably connected to the optical module 10 in a first direction, and a user can take, place, push or pull the optical module 10 through the push-pull piece 30, so as to facilitate the user to install the optical module 10 to the network equipment or take the optical module 10 out of the network equipment. Moreover, the push-pull piece 30 is connected to the dust cover 20, and the connection manner includes but is not limited to abutting. The first direction is perpendicular to the plane where the optical port 111 is located.

[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. In the case that the optical module assembly switches from the normal state to the installed state, the push-pull piece 30 is connected to the dust cover 20, the push-pull piece 30 moves in the first direction and drives the dust cover 20 to rotate to the side away from the optical port 111, so as to open the optical port 111.

[0053] The normal state refers to the default state when the optical module 10 is not connected to the network equipment. The installed state refers to the state when the optical fiber 80 is inserted into the optical port 111 and the optical module 10 is inserted into the network equipment and the connection is completed.

[0054] From the above description, it can be known that the rotatable dust cover 20 is installed at the optical port 111 of the optical module 10. When the optical module assembly is in the normal state, i.e. the optical module 10 is not connected to the network equipment, the dust cover 20 closes the optical port 111, forming a physical barrier to effectively block dust and other foreign matters from entering the inside of the optical module 10, and providing good dust protection when the optical module 10 is not working. When it is necessary to install the optical module 10 to the network equipment (i.e. in the case that the optical module assembly switches from the normal state to the installed state), the user can move the push-pull piece 30 in the first direction to drive the dust cover 20 to rotate to the side away from the optical port 111, so as to open the optical port 111. In this process, the user does not need to manually operate the dust cover 20, avoiding the dust that may be introduced when the user manually opens the dust cover 20.

[0055] In one embodiment, the dust cover 20 is rotatably connected with the shell 11 through the rotating shaft 40, and can rotate around the rotating shaft 40 to close or open the light port 111. Specifically, the dust cover 20 includes a connecting end 22 and a free end 21. The connecting end 22 is sleeved on the rotating shaft 40, the rotating shaft 40 is located at the edge of the light port 111, and the rotating shaft 40 is fixed to the optical module 10. In the case that the optical module 10 is switched from the normal state to the installation state, the free end 21 rotates to the side away from the light port 111 around the rotating shaft 40.

[0056] The connecting mode of the rotating shaft 40 makes the connection structure of the dust cover 20 and the light port 111 relatively simple, and the manufacturing and installation difficulty is relatively low. Moreover, the rotating shaft 40 is arranged at the edge of the light port 111, and the dust cover 20 can be well fitted to the light port 111 to better close the light port 111 and improve the dustproof effect.

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

[0058] Further, the maximum opening angle of the dust cover 20 can be 70° to 90°, that is, in the case that the optical module assembly is switched from the normal state to the installation state, the maximum rotation angle of the free end 21 of the dust cover 20 is 70° to 90°. This can make the light port 111 be fully opened, which is convenient for inserting the optical fiber 80.

[0059] Illustratively, 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 protruding part 221, which is located at the side of the rotating shaft 40 away from the free end 21, that is, in the direction along which the free end 21 points to the connecting end 22, the protruding part 221 exceeds the rotating shaft 40. The push-pull piece 30 is provided with a push-pull part 31. In the case that the optical module assembly is switched from the normal state to the installation state, the push-pull part 31 abuts against the protruding part 221, and the push-pull part 31 applies a force in the first direction to the protruding part 221 to drive the free end 21 of the dust cover 20 to rotate to the side away from the light port 111.

[0061] Since the push-pull part 31 directly abuts against the protruding part 221 of the connecting end 22 of the dust cover 20, without the need for an intermediate transmission assembly, the force of the push-pull piece 30 can be directly and efficiently transmitted to the dust cover 20 to drive the dust cover 20 to rotate and open the light port 111. Moreover, the design of the protruding part 221 is also conducive to saving 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 pre-tightening member comprises a torsion spring 50, which is sleeved on the rotating shaft 40. The torsion spring 50 comprises at least two force applying arms. The dust cover 20 and the optical module 10 are connected with different force applying arms and receive pre-tightening force from different directions. In other words, the torsion spring 50 is sleeved on the rotating shaft 40, and different directions of force are applied to the dust cover 20 and the optical module 10 by the force applying arms of the torsion spring 50, so as to achieve the pre-tightening effect on the dust cover 20. In the normal state, the torsion spring 50 has a first pre-tightening force. In the case that the optical module 10 is switched from the normal state to the installed state, the torsion spring 50 has a second pre-tightening force. The first pre-tightening force is smaller than the second pre-tightening force.

[0070] In this way, in the normal state, the first pre-tightening force provided by the torsion spring 50 is small, which can maintain the dust cover 20 in the closed state under smaller energy consumption, and can ensure the dustproof effect and avoid material fatigue caused by excessive stress. In the installed state, the optical fiber 80 is inserted into the optical port 111, which prevents the dust cover 20 from closing to the optical port 111. After the optical fiber 80 is pulled out of the optical port 111, the second pre-tightening force can make the dust cover 20 quickly return to the closed state, so as to timely seal the optical port 111 and prevent dust and other foreign matters from entering the inside of the optical module 10.

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

[0072] The first force applying arm 51 and the second force applying arm 52 are connected with the dust cover 20 at the same time, which can uniformly apply force to the dust cover 20 from two different positions. Compared with applying force at only one end, the dust cover 20 can be more stably closed to the optical port 111 in the normal state, which avoids the situation that the dust cover 20 is skewed or not tightly closed due to uneven force, and improves the dustproof effect.

[0073] Further, the dust cover 20 is provided with a connecting groove 23, and the first force applying arm 51 and the second force applying arm 52 are inserted into the connecting groove 23. In this way, the connecting groove 23 provides a stable fixing position for the force applying arms of the torsion spring 50, which can effectively prevent the force applying arms from being displaced or separated from the dust cover 20 due to external force during the plugging and unplugging of the optical module 10. In addition, the connecting groove 23 can contact the first force applying arm 51 and the second force applying arm 52 in multiple directions, and the contact area is large, so that the connection between the torsion spring 50 and the dust cover 20 is more firm.

[0074] In one embodiment, the shell 11 comprises a plug end 114 for plugging into a network device, the plug end 114 and the optical port 111 are located at opposite ends of the shell 11 respectively. The first direction comprises a first sub-direction and a second sub-direction pointing in opposite directions, the direction of the optical port 111 pointing to the plug end 114 is the first sub-direction, and the direction of the plug end 114 pointing to the optical port 111 is the second sub-direction. In the case of switching from the normal state to the installed state of the optical module assembly, the push-pull piece 30 moves along the first sub-direction.

[0075] After being arranged in this way, the direction in which the user operates the push-pull piece 30 to open the dust cover 20 is consistent with the direction in which the optical module 10 is inserted into the network device, which conforms to the conventional operation habit, reduces the complexity of operation, improves the installation efficiency, and facilitates the rapid deployment of the optical module 10.

[0076] In one embodiment, the dust cover 20 further comprises a limiting portion 25 located between the connecting end 22 and the free end 21, and in the installed state of the optical module assembly, 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] In this way, when the user needs to pull out the optical module 10 from the network device, the push-pull piece 30 is operated to move along the second sub-direction. At this time, since 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, the push-pull portion 31 can apply a force along the second sub-direction to the limiting portion 25 of the dust cover 20, which can promote the free end 21 of the dust cover 20 to rotate in the direction towards the optical port 111, so as to make the dust cover 20 close faster. That is to say, the present scheme realizes the linkage of the closing action of the dust cover 20 and the pulling-out operation of the optical module 10, simplifies the operation process when the user removes the optical module 10 from the network device, and does not need the user to manually close the dust cover 20 additionally, thereby improving the operation portability.

[0078] In one embodiment, the optical module assembly further comprises a locking piece 60, which is slidably connected to the optical module 10 along the first direction. The sliding connection mode can be a guide rail and sliding block connection, a friction contact sliding connection, but is not limited thereto.

[0079] In the installed state of the optical module assembly, the locking piece 60 is used to lock the optical module 10. The optical module assembly further comprises an unlocked state, in which the locking piece 60 is used to unlock the optical module 10, and the dust cover 20 encloses the optical port 111.

[0080] In the case of switching from the installed state to the unlocked state of the optical module assembly, the push-pull piece 30 is connected with the locking piece 60, and the push-pull piece 30 moves along the second sub-direction to drive the locking piece 60 to move along the second sub-direction, so as to unlock the optical module 10.

[0081] Through the connection design of the push-pull piece 30 and the locking piece 60, in the case of switching the optical module assembly from the mounted state to the unlocked state, only the push-pull piece 30 needs to be operated to move along the second sub-direction, so as to drive the locking piece 60 to move synchronously to unlock the optical module 10, which is simple and convenient to operate, reduces the complex unlocking steps, and improves the plugging efficiency of the optical module 10.

[0082] In summary, in the scheme provided in the embodiment, in the normal state, the dust cover 20 can close the optical port 111 to block dust from entering. In the case of switching the optical module assembly from the normal state to the mounted state, the user pushes the push-pull piece 30 to move the push-pull piece 30 along the first sub-direction, which drives the dust cover 20 to open and at the same time inserts the optical module 10 into the network equipment. In the case of switching the optical module assembly from the mounted state to the unlocked state, the user pulls the push-pull piece 30 to move the push-pull piece 30 along the second sub-direction, which drives the locking piece 60 to move along the second sub-direction, thereby unlocking the optical module 10. The user moves the same push-pull piece 30 in different directions to respectively realize the opening of the dust cover 20, the installation of the optical module 10, and the unlocking of the optical module 10, and the like, and the integration is high.

[0083] It should be noted that when the optical module assembly is in the unlocked state, or in the case of switching from the mounted state to the unlocked state, the user can manually close the dust cover 20, or use the pre-tightening piece, the limiting portion 25, and the like described in the above embodiment to realize the automatic closing of the dust cover 20, which is not limited in the present application.

[0084] In addition, how the locking piece 60 locks or unlocks the optical module 10 can refer to related technologies. However, for the convenience of understanding, an example is given in the present application: the locking piece 60 is slidably connected to the outer wall of the base 113 of the shell 11, the locking piece 60 has two clamping portions 61, in the mounted state of the optical module assembly, the clamping portions 61 are used for clamping and cooperating with the clamping and cooperating portions of the network equipment in the first direction, so as to lock the optical module 10. In the case of switching the optical module assembly from the mounted state to the unlocked state, the push-pull piece 30 drives the locking piece 60 to move along the second sub-direction, and the clamping portions 61 are separated from the clamping and cooperating portions of the network equipment, thereby unlocking the optical module 10.

[0085] In one embodiment, the locking piece 60 is fixedly connected with the push-pull piece 30, and at this time the push-pull piece 30 can be slidably connected with the optical module 10 through the locking piece 60.

[0086] The fixed connection mode can be, but is not limited to, clamping, threaded connection, bonding or one-piece forming. The fixed connection mode makes the connection between the locking member 60 and the push-pull member 30 more stable, and ensures the action consistency of the locking member 60 and the push-pull member 30. When the push-pull member 30 moves, the locking member 60 can also move correspondingly to realize the locking or unlocking of the optical module 10, and the action deviation caused by loose connection or gap will not occur.

[0087] It should be noted that the maximum stroke of the locking member 60 moving in the first direction can be set as needed, and the optical module 10 can be provided with a corresponding limiting member to enable the locking member 60 to slide within a predetermined stroke and move the optical module 10 through the limiting member. The present application does not make specific limitations on this.

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

[0089] In another embodiment, in the normal state and the installed state, the push-pull member 30 is separated from the locking member 60, and in the case that the optical module assembly switches from the installed state to the unlocked state, the push-pull member 30 abuts against the locking member 60 to exert a force on the locking member 60 towards the second sub-direction.

[0090] In this way, in the normal state and the installed state, the push-pull member 30 is separated from the locking member 60, so that the operations in these two states are relatively independent. When installing the optical module 10, the user can push the optical module 10 through the push-pull member 30 and open the dust cover 20 to smoothly plug the optical module 10 into the network equipment, and at this time the locking member 60 will not interfere with the installation operation. In the case of switching from the installed state to the unlocked state, the push-pull member 30 abuts against the locking member 60 and exerts a force, realizing the switching of functions. This design allows the push-pull member 30 and the locking member 60 to have a certain independence in structure, facilitating the separate maintenance, replacement or improvement of them.

[0091] Please refer to Figure 6 In one embodiment, the optical module assembly further comprises a first reset member arranged between the locking member 60 and the optical module 10. When the optical module 10 is in the 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 exert a restoring force on the locking member 60 along the first sub-direction.

[0092] When the optical module assembly is in the unlocked state, the first reset member can exert a restoring force along the first sub-direction on the locking member 60, so that the locking member 60 automatically returns to the initial position (i.e. the position in the normal state). This automatic reset function reduces the need for manual intervention, ensures that the locking member 60 can be accurately positioned after each unlocking, and prepares for the next locking operation, thereby improving the convenience of operation of the optical module assembly.

[0093] The number of the first reset member can be two, and the first reset member can be a spring, a spring sheet, an elastic rubber, etc., but is not limited thereto.

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

[0095] Specifically, the sidewall of the base 113 of the optical module 10 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 portion 62 extending into 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 portion 62.

[0096] Further, the optical module assembly can further include a second reset member, which is arranged between the locking member 60 and the optical module 10. When the optical module 10 is in the normal state, the first reset member is in the natural state, and when the optical module assembly is in the installed state, the second reset member is used to exert a restoring force along the second sub-direction on the locking member 60.

[0097] The number of the second reset member can also be two, and the second reset member can be a spring, a spring sheet, an elastic rubber, etc., but is not limited thereto

[0098] Specifically, the second reset member is a second reset spring 72, a second mounting groove is formed in an outer wall of the base 113 of the optical module 10, the second reset spring 72 is arranged in the second mounting groove, the locking member 60 has a second abutting portion 63 extending towards the second mounting groove, one end of the second reset spring 72 along a first sub-direction is fixed in the shell 11, and one end of the second reset spring 72 along a second sub-direction is in abutting cooperation with the second abutting portion 63. When the optical module assembly is in a normal state, the second reset spring 72 is in a natural state, and when the optical module assembly is in an installed state, the second reset spring 72 is in a stretched state. That is, in the case that the optical module assembly is switched from the normal state to the installed state, the second reset spring 72 is stretched to store elastic potential energy. When the locking member 60 is unlocked, the second reset spring 72 can provide elastic force for moving the locking member 60 along the second sub-direction, thereby assisting the user in pulling the locking member 60 through the push-pull member 30. At the same time, since the push-pull member 30 is fixedly connected with 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 optical port 111, thereby closing the optical port 111.

[0099] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
