Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, in particular to an optical module. Background Art

[0002] As is well known, an optical module has the characteristic of hot pluggability, that is, without turning off the power supply, by plugging and unplugging the optical module into / from the cage of the device, the connection or disconnection between the optical module and the device can be achieved. When the optical module is inserted into the cage, the outer shell of the optical module is locked by the cage tongue in the locked state, and the optical module remains inserted into the cage; when the optical module is pulled out of the cage, the built-in unlocking device of the optical module is operated, and the cage tongue is pushed by the unlocking device, so that the cage tongue is changed from the locked state to the unlocked state to help the optical module be pulled out of the cage. It can be seen that a convenient unlocking device can help users perform the plugging and unplugging operations of the optical module more easily. At the same time, the setting of the unlocking device can also reduce the direct touch of the interface of the optical module and reduce the risk of damaging the interface due to misoperation. Therefore, the setting of the unlocking device greatly improves the operation convenience and maintainability of the optical module. However, most of the currently built-in unlocking devices of optical modules are complex in structure, cumbersome in the assembly process and high in cost. Summary of the Utility Model

[0003] In view of this, the utility model provides an optical module, aiming at solving the problems that the built-in unlocking device of the existing optical module is complex in structure, cumbersome in the assembly process and high in cost.

[0004] The utility model provides an optical module, which includes an upper cover and a bottom shell. The upper cover is provided with an upper sliding groove, and the bottom shell is provided with a lower sliding groove. The upper sliding groove and the lower sliding groove are arranged correspondingly. The optical module further includes an unlocking device, which includes an unlocking pull belt, a connecting part and an unlocking piece. The upper end of the connecting part is arranged in the upper sliding groove, the lower end of the connecting part is arranged in the lower sliding groove, the rear end of the connecting part is connected to one end of the unlocking pull belt, and the front end of the connecting part is connected to the unlocking piece;

[0005] When the unlocking pull belt pulls the connecting part to slide backward along the upper sliding groove and the lower sliding groove, the connecting part drives the unlocking piece to move backward, so that the unlocking piece presses the cage tongue, and the cage tongue is changed from the locked state to the unlocked state.

[0006] Further, the bottom shell is provided with an installation position, and the unlocking device further includes a spring. The spring is arranged in the installation position and connected to the inner side of the connecting part;

[0007] When the unlocking pull belt applies a pulling force to the connecting part, the connecting part drives the spring to be compressed backward. When the pulling force applied by the unlocking pull belt to the connecting part is removed, the compressed spring pushes the connecting part to reset forward.

[0008] Furthermore, a retaining piece is arranged inside the connecting part. One side of the retaining piece contacts the spring, and the other side of the retaining piece contacts the mounting position.

[0009] When the unlocking pull strap applies a pulling force to the connecting part, the retaining piece drives the spring to be compressed backward. When the pulling force applied by the unlocking pull strap to the connecting part is removed, the compressed spring pushes the retaining piece to reset forward.

[0010] Furthermore, the mounting position is a square structure with open upper and one side surfaces.

[0011] Furthermore, the unlocking member is a U-shaped-like structure. One end of the opening side of the U-shaped-like structure is connected to the connecting part, and the bottom case is provided with a limiting groove, and the U-shaped-like structure is arranged in the limiting groove.

[0012] When the unlocking pull strap pulls the connecting part to slide backward along the upper sliding groove and the lower sliding groove, the connecting part drives the U-shaped-like structure to move backward along the limiting groove, so that the other end of the opening side of the U-shaped-like structure squeezes the cage tongue piece, causing the cage tongue piece to switch from the locked state to the unlocked state.

[0013] Furthermore, the other end of the unlocking pull strap is provided with a pull ring structure, and an anti-slip component is arranged on the upper surface of the pull ring structure.

[0014] Furthermore, the anti-slip component is a concave structure, and four parallel convex lines are arranged in the concave structure.

[0015] Furthermore, an upper protruding piece is arranged at the upper end of the connecting part, and a lower protruding piece is arranged at the lower end of the connecting part. An upper clamping groove is arranged at the position corresponding to the upper protruding piece on the upper cover, and a lower clamping groove is arranged at the position corresponding to the lower protruding piece on the bottom case.

[0016] When the unlocking pull strap pulls the connecting part to slide backward along the upper sliding groove and the lower sliding groove, the upper protruding piece moves backward along the upper clamping groove, and at the same time the lower protruding piece moves backward along the lower clamping groove.

[0017] Furthermore, the upper cover and the bottom case are connected by screws.

[0018] Furthermore, heat-conducting bosses are arranged at the positions corresponding to the chip on the inner sides of the upper cover and / or the bottom case.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: An optical module includes an upper cover and a bottom shell. The upper cover is provided with an upper sliding groove, and the bottom shell is provided with a lower sliding groove. The upper sliding groove and the lower sliding groove are correspondingly arranged. The optical module further includes an unlocking device, which includes an unlocking pull belt, a connecting part, and an unlocking piece. The upper end of the connecting part is arranged in the upper sliding groove, and the lower end of the connecting part is arranged in the lower sliding groove. The rear end of the connecting part is connected to one end of the unlocking pull belt, and the front end of the connecting part is connected to the unlocking piece. When the optical module is inserted into the cage of the device, the cage tongue remains in the locked state, and the optical module is locked by the cage tongue in the locked state and remains inserted into the cage. When it is necessary to pull out the optical module from the cage of the device, pull the unlocking pull belt, and drive the connecting part to slide backward along the upper sliding groove and the lower sliding groove through the unlocking pull belt. The connecting part drives the unlocking piece to move backward, so that the unlocking piece presses the cage tongue, causing the cage tongue to switch from the locked state to the unlocked state, facilitating the extraction of the optical module from the cage. It can be seen that when the optical module is in use, the plugging and unplugging actions can be smoothly completed through the unlocking device. Moreover, the structural design of the upper sliding groove and the lower sliding groove of the optical module is relatively simple. Only by aligning the upper sliding groove and the lower sliding groove and then arranging the connecting part of the unlocking device between the upper sliding groove and the lower sliding groove can the assembly be completed. And the movement relationship of the connecting part sliding along the upper sliding groove and the lower sliding groove is clear, and the transmission of the unlocking piece can be completed without a complex transmission device. In addition, the unlocking piece only needs to press the cage tongue to make the cage tongue switch from the locked state to the unlocked state. Such an operation method is simple, and complex components and mechanical devices can be reduced in the design and manufacturing process, thereby reducing the manufacturing cost and the complexity of maintenance. Therefore, the unlocking device provided by the optical module has a simple structure, is easy to assemble, and has a low cost. Description of the Drawings

Detailed implementation manners

[0030] Next, the solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0031] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0033] Please refer to Figures 1-7 As shown, the present utility model provides an optical module 10, which includes an upper cover 11 and a bottom shell 12. The upper cover 11 is provided with an upper sliding groove 13, and the bottom shell 12 is provided with a lower sliding groove 14. The upper sliding groove 13 and the lower sliding groove 14 are correspondingly arranged. The optical module 10 further includes an unlocking device, and the unlocking device includes an unlocking pull belt 21, a connecting portion 22, and an unlocking member 23. The upper end of the connecting portion 22 is arranged in the upper sliding groove 13, the lower end of the connecting portion 22 is arranged in the lower sliding groove 14, the rear end of the connecting portion 22 is connected to one end of the unlocking pull belt 21, and the front end of the connecting portion 22 is connected to the unlocking member 23;

[0034] When the unlocking pull belt 21 pulls the connecting portion 22 to slide backward along the upper sliding groove 13 and the lower sliding groove 14, the connecting portion 22 drives the unlocking member 23 to move backward, so that the unlocking member 23 presses the cage tongue piece 31, causing the cage tongue piece 31 to switch from the locked state to the unlocked state.

[0035] Specifically, when the cage tongue piece 31 switches from the locked state to the unlocked state, the optical module 10 can be conveniently and quickly pulled out from the cage 30 of the device. Further, for the recycling use of the optical module 10, the optical module 10 can also be provided with a reset structure. By using the reset structure, when the pulling force of the unlocking pull belt 21 pulling the connecting portion 22 is removed, the connecting portion 22 slides forward along the upper sliding groove 13 and the lower sliding groove 14, and the connecting portion 22 sliding forward drives the unlocking member 23 to move forward, so that the unlocking member 23 is reset, preparing for the next operation of pressing the cage tongue piece 31 to switch the cage tongue piece 31 from the locked state to the unlocked state. In addition, the unlocking pull belt 21, the connecting portion 22, and the unlocking member 23 are integrally formed by in-mold injection molding process, which is simple and convenient to manufacture. Of course, the upper sliding groove 13 and the lower sliding groove 14 can also be only arranged on the upper cover 11 or the bottom shell 12. However, compared with the design of respectively arranging the upper sliding groove 13 and the lower sliding groove 14 on the upper cover 11 and the bottom shell 12, the sliding of the unlocking member 23 in the latter case will be more stable and smooth.

[0036] Using the optical module 10 provided by the embodiment of the present utility model, the plugging and unplugging operations can be successfully completed through the unlocking device. Specifically: pushing the unlocking strap 21 forward, the unlocking strap 21 drives the upper cover 11 and the bottom shell 12 of the optical module 10 to be inserted into the cage 30 of the device; pulling the unlocking strap 21 backward, the unlocking strap 21 drives the unlocking member 23 to squeeze the cage tongue 31, so that the cage tongue 31 is converted from the locked state to the unlocked state, and the upper cover 11 and the bottom shell 12 of the optical module 10 are pulled out of the cage 30 of the device. Moreover, the structural designs of the upper sliding groove 13 and the lower sliding groove 14 of the optical module 10 are relatively simple. Just align the upper sliding groove 13 and the lower sliding groove 14, and then set the connecting portion 22 of the unlocking device between the upper sliding groove 13 and the lower sliding groove 14 to complete the assembly. And the movement relationship of the connecting portion 22 sliding along the upper sliding groove 13 and the lower sliding groove 14 is clear, and the unlocking member 23 can be driven without a complex transmission device. In addition, the unlocking member 23 only needs to squeeze the cage tongue 31 to convert the cage tongue 31 from the locked state to the unlocked state. Such an operation method is simple, and complex components and mechanical devices can be reduced during the design and manufacturing processes, thereby reducing the manufacturing cost and the complexity of maintenance. Therefore, the unlocking device provided by the optical module 10 has a simple structure, is easy to assemble and has a low cost.

[0037] In some embodiments of the present application, the bottom shell 12 is provided with an installation position 15, and the unlocking device further includes a spring 24. The spring 24 is disposed in the installation position 15 and is connected to the inner side of the connecting portion 22;

[0038] When the unlocking strap 21 applies a pulling force to the connecting portion 22, the connecting portion 22 drives the spring 24 to be compressed backward. When the pulling force applied by the unlocking strap 21 to the connecting portion 22 is removed, the compressed spring 24 pushes the connecting portion 22 to reset forward.

[0039] Specifically, the spring 24 is a reset structure provided for the optical module 10. The spring 24 has elasticity and can automatically return to its original state after the external force disappears without external force intervention, realizing the function of automatic reset. Moreover, as a reset structure, the spring 24 can improve the stability of the device or mechanical components, ensuring that they maintain a normal position and state during the working process. The connection method between the spring 24 and the connection part 22 can be various. For example, a hook is provided inside the connection part 22, and the hook hooks the spring 24, so that the movement of the unlocking strap 21 can be transmitted to the spring 24 through the connection part 22, enabling the spring 24 to complete the compression process and further complete the reset process. Of course, the installation position 15 can be directly set on the bottom case 12, or directly set on the upper cover 11, or even set on both the upper cover 11 and the bottom case 12, as long as the above-mentioned compression and reset process can be achieved. The specific setting method of the installation position 15 is determined according to the use environment of the optical module 10, and will not be elaborated one by one here.

[0040] In some embodiments of the present application, a retaining piece 25 is provided inside the connection part 22. One side of the retaining piece 25 contacts the spring 24, and the other side of the retaining piece 25 contacts the installation position 15;

[0041] When the unlocking strap 21 applies a pulling force to the connection part 22, the retaining piece 25 drives the spring 24 to be compressed backward. When the unlocking strap 21 removes the pulling force applied to the connection part 22, the compressed spring 24 pushes the retaining piece 25 to reset forward.

[0042] Specifically, a retaining piece 25 is provided inside the connection part 22 for connecting the spring 24 to the connection part 22 through the retaining piece 25. Compared with providing a hook inside the connection part 22, the retaining piece 25 can provide a more stable compression force, avoiding the problem of unstable compression force caused by the friction or looseness of the hook, and can also reduce the possibility of the spring 24 failing due to the hook falling off or being damaged, improving the overall reliability of the optical module 10. Moreover, the structure of the retaining piece 25 is simple and does not require a complex assembly process. Even in a limited space, the retaining piece 25 can connect the spring 24 more flexibly, making full use of the space. In addition, the design of the retaining piece 25 can make the maintenance of the spring 24 more convenient, and it is also easy to achieve different compression requirements by adjusting or replacing the retaining piece 25, ensuring that the required compression force and displacement are achieved within the design range.

[0043] In some embodiments of the present application, the installation position 15 is a square structure with both the upper surface and one side surface being open surfaces.

[0044] Specifically, the upper surface of the mounting position 15 is an open surface, facilitating the assembly of the spring 24 onto the mounting position 15 from above; one side surface of the mounting position 15 is an open surface, facilitating the assembly of the spring 24 onto the mounting position 15 from one side. The square mounting position with open surfaces on both the upper surface and one side surface can meet different assembly requirements, improve the flexibility of assembly, and reduce the possibility of accidents caused by the failure of a single mounting position (such as only side mounting), thereby enhancing the overall safety of the optical module 10. In comparison, when assembling the spring 24 onto the mounting position 15 from above and from one side, the former assembly method is simpler and more in line with people's assembly habits. Assembling the spring 24 onto the mounting position 15 from above facilitates the installation and removal of the spring 24, improving production efficiency.

[0045] In some embodiments of the present application, the unlocking member 23 has a U-shaped structure. One end of the open side of the U-shaped structure is connected to the connecting portion 22, and the bottom case 12 is provided with a limiting groove 16, and the U-shaped structure is disposed in the limiting groove 16;

[0046] When the unlocking strap 21 pulls the connecting portion 22 to slide backward along the upper sliding groove 13 and the lower sliding groove 14, the connecting portion 22 drives the U-shaped structure to move backward along the limiting groove 16, so that the other end of the open side of the U-shaped structure presses the cage tongue 31, causing the cage tongue 31 to switch from the locked state to the unlocked state.

[0047] Specifically, when the optical module 10 is not inserted into the cage 30 of the device, and when the optical module 10 is inserted into the cage 30 and the cage tongue 31 is in the locked state, the unlocking member 23 is located in the limiting groove 16. When the cage tongue 31 switches from the locked state to the unlocked state, the unlocking member 23 moves out of the limiting groove 16 and presses the cage tongue 31. The unlocking member 23 has a U-shaped structure. On the basis of providing more stable support, its open slot can also reduce the surface area in contact with the cage tongue 31, reducing damage and wear to the cage tongue 31. Of course, the limiting groove 16 can be directly provided on the bottom case 12, or directly provided on the upper cover 11, or even provided on both the upper cover 11 and the bottom case 12, as long as the above-mentioned pressing process can be achieved. The specific setting method of the limiting groove 16 is determined according to the usage environment of the optical module 10, and will not be elaborated here one by one.

[0048] In some embodiments of the present application, the other end of the unlocking strap 21 is provided with a pull-ring structure, and an anti-slip member is provided on the upper surface of the pull-ring structure.

[0049] Specifically, the pull-ring structure is an operating point when the user maintains and replaces the optical module 10. To facilitate the user's maintenance and replacement work, an anti-slip component is provided on the upper surface of the pull-ring structure. The anti-slip component is beneficial to improving the comfort of the user's operation, thereby enhancing the overall usage experience of the optical module 10.

[0050] In some embodiments of the present application, the anti-slip component is a recessed structure 211, and four parallel convex lines 212 are provided in the recessed structure 211.

[0051] Specifically, the recessed structure 211, the four parallel convex lines 212 and the pull-ring structure are integrally formed, without the need for a complex connection structure design. In addition, the design of the recessed structure 211 can increase the friction between the user and the upper surface of the pull-ring structure, thereby improving the anti-slip performance. The design of the four parallel convex lines 212 can further effectively improve the anti-slip performance, increase the friction and disperse the pressure. Of course, in addition to the above four parallel convex lines 212, other anti-slip patterns can also be provided in the recessed structure 211, and no further examples will be given here.

[0052] In some embodiments of the present application, an upper protruding part 221 is provided at the upper end of the connecting part 22, a lower protruding part 222 is provided at the lower end of the connecting part 22, an upper card slot is provided at the position of the upper cover 11 corresponding to the upper protruding part 221, and a lower card slot 17 is provided at the position of the bottom shell 12 corresponding to the lower protruding part 222;

[0053] When the unlocking strap 21 pulls the connecting part 22 to slide backward along the upper sliding groove 13 and the lower sliding groove 14, the upper protruding part 221 moves backward along the upper card slot, and at the same time the lower protruding part 222 moves backward along the lower card slot 17.

[0054] Specifically, on the basis of the upper sliding groove 13 and the lower sliding groove 14 of the optical module 10, an upper card slot and a lower card slot 17 are further provided, so that the sliding amplitude of the unlocking device is more controllable and the sliding process is more stable. The upper protruding part 221 and the upper card slot cooperate with each other, and the upper card slot can limit the moving range of the upper protruding part 221 to ensure that the upper protruding part 221 moves within a specific trajectory range. At the same time, the lower protruding part 222 and the lower card slot 17 cooperate with each other, and the lower card slot 17 can limit the moving range of the lower protruding part 222 to ensure that the lower protruding part 222 moves within a specific trajectory range. This can effectively prevent damage caused by the unlocking device slipping out of the sliding design range of the optical module 10, and helps to ensure the stable operation of the mechanical system of the optical module 10.

[0055] In some embodiments of the present application, the upper cover 11 and the bottom shell 12 are connected by screws.

[0056] Specifically, screw connection is a common and practical connection method, applicable to different engineering and manufacturing applications. At the corresponding four corner positions of the upper cover 11 and the bottom case 12, screw holes are respectively provided, and four locking screws 18 are used to screw-connect the upper cover 11 and the bottom case 12. Screw connection can be easily disassembled, facilitating maintenance and replacement of components. Moreover, by adjusting the tightening degree of the locking screws 18, the tightness between the upper cover 11 and the bottom case 12 can be flexibly adjusted. After correctly installing the locking screws 18 on the upper cover 11 and the bottom case 12, a stable connection can be provided, enabling the upper cover 11 and the bottom case 12 to have a relatively high load-bearing capacity and anti-vibration ability, and the cost is relatively low, making it easy to process and install.

[0057] In some embodiments of the present application, heat-conducting bosses 19 are provided at positions on the inner sides of the upper cover 11 and / or the bottom case 12 corresponding to the chips.

[0058] Specifically, the upper cover 11 and the bottom case 12 of the optical module 10 are mainly used to protect the internal circuit. The most important electrical component in the internal circuit is the chip. Heat-conducting bosses 19 are provided at positions on the inner sides of the upper cover 11 and / or the bottom case 12 corresponding to the chips, aiming to improve the heat dissipation effect of the chips. The chips in the optical module 10 generate a large amount of heat during operation. To ensure the stable operating temperature of the chips and prevent overheating, it is necessary to effectively dissipate the heat of the chips. The heat-conducting bosses 19 can help quickly conduct the heat generated by the chips to the upper cover 11 and / or the bottom case 12, and dissipate the heat through the upper cover 11 and / or the bottom case 12, thereby keeping the operating temperature of the chips within a safe range. The heat-conducting bosses 19 usually achieve the heat dissipation effect by increasing the contact area and the thermal conductivity of the heat-conducting material. It can increase the heat conduction efficiency between the chips and the outer shell (including the upper cover 11 and the bottom case 12), thereby effectively transferring the heat to the surface of the outer shell, making the heat dissipation more efficient, effectively reducing the operating temperature of the chips, extending the service life of the optical module 10, and ensuring its performance and stability. During actual use, according to the size of the inner cavity formed by enclosing the outer shell, it is ultimately determined whether to set the heat-conducting bosses 19 on the upper cover 11, the bottom case 12, or both the upper cover 11 and the bottom case 12.

[0059] The optical module 10 provided by the embodiment of the present utility model addresses the problems that the unlocking device of the optical module 10 in the current market has a complex structural design, is difficult to assemble, affects production efficiency, and the pull-ring designs are all the same without enterprise recognition. It simplifies the number of structural designs of the unlocking device, optimizes the design scheme, makes the structure of the optical module 10 convenient for assembly and disassembly. At the same time, it designs a unique unlocking strap 21 shape and pull-ring structure with a unique design style. Compared with the square, regular or identical pull-rings in the market, the unlocking strap 21 of our optical module 10 has a unique shape, adopts curve design elements, has a strong sense of design, and has the characteristics different from the popular ones, which can greatly improve the recognition of the enterprise image.

[0060] It should be noted that the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions conflicts with each other or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0061] The above are only partial or preferred embodiments of the present utility model. Whether in terms of text or drawings, they cannot limit the scope of protection of the present utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the overall concept of the present utility model, or directly / indirectly applied in other related technical fields, is included in the scope of protection of the present utility model.
