[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese Patent Application No. 202420870529.8, filed on April 24, 2024, entitled "An optical module unlocking device and an optical module", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of optical module technology, and more specifically, to an optical module unlocking device and an optical module. Background Technology

[0004] SFP (Small Form Factor Pluggable) optical modules are small, pluggable modules commonly used in network devices such as switches and routers, capable of carrying high-speed data transmission.

[0005] As shown in Figure 1, the existing unlocking mechanism of an SFP optical module includes components such as a module base, a wire hook, a spring, an unlocking block, a pressure plate, and mounting screws. Its working principle is as follows: the wire hook is engaged in a circular groove at the head of the base. When the wire hook rotates around the groove to a horizontal plane, the protrusion on the hook lifts the unlocking block, the protrusion on the unlocking block sinks, and the spring is compressed, unlocking the optical module. When the wire hook is lowered, the spring causes the unlocking block to automatically reset. This unlocking mechanism is a lever-type unlocking mechanism. Since the operating space of the wire hook-driven unlocking structure is limited, using a pull-belt driven unlocking structure could effectively improve the operating space. However, existing unlocking mechanisms are difficult to adapt to pull-belts. Therefore, we propose an optical module unlocking device and an optical module.

[0044] The technical solutions of the embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0045] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. It should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figures, or the orientation or positional relationship commonly used when the product of this disclosure is in use. They are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Please refer to Figures 2 to 4. The first aspect of the technical solution of this disclosure provides an optical module unlocking device, including a base 100. The optical module unlocking device also includes a pull strap 200, an unlocking component 300, and a top cover 400. The unlocking component 300 includes an unlocking element 310, a locking hook 320, and a spring 330. The pull strap 200 is fixedly connected to the unlocking element 310. The locking hook 320 is disposed on the base 100 and movably connected to the base 100. The spring 330 is disposed on the base 100 and fixedly connected to the unlocking element 310. The unlocking element 310 is disposed on the top of the locking hook 320. The top cover 400 is disposed on the top of the unlocking device and the top cover 400 is provided with a reset element 410 configured to assist the locking hook 320 in resetting.

[0047] Specifically, the locking hook 320 is configured to unlock the optical module. When the pull strap 200 is pulled out, the unlocking component 310 presses down on the irregular area in the middle of the locking hook 320. When the pull strap 200 resets, the reset component 410 presses down on the end of the locking hook 320 away from the pull strap 200. This irregular area is the protruding part of the locking hook 320. When the pull strap 200 is pulled out, the unlocking component 310 presses down on the protruding part, causing the portion of the locking hook 320 that locks the optical module to shift downwards, thereby unlocking the optical module. That is, after unlocking, the optical module can detach from the device cage; when the locking hook is locked on the optical module, the optical module cannot detach from the device cage. Both the locking hook 320 and the unlocking component 310 are irregularly shaped metal parts. The spring 330 is configured to automatically reset after the pull strap 200 is pulled out; pulling out the pull strap 200 unlocks the optical module. When the pull strap 200 is pulled out, the unlocking member 310 applies pressure to the spring 330, compressing the spring 330, and the spring 330 is in a compressed state; after no force is applied to the pull strap 200, the spring 330 returns from the compressed state to the naturally extended state, and applies the opposite force to the pull strap 200, causing it to automatically reset.

[0048] It should be noted that since the locking hook 320 remains in the unlocked state of the optical module after the pull strap 200 is pulled out and automatically resets, a reset component 410 needs to be provided on the top of the top cover 400 to allow the locking hook 320 to be pressed down after the pull strap 200 is retracted, thereby locking the optical module. That is, the reset component 410 is configured to apply downward pressure to the locking hook 320, causing the locking hook 320 to tilt upward, thereby locking the optical module.

[0049] The optical module unlocking device and optical module provided in this embodiment adopt a pull strap 200 design to enhance the unlocking operation space of the optical module. The lever-type unlocking mechanism is achieved through the coordinated use of the pull strap 200, unlocking component 310, locking hook 320, spring 330, and reset component 410. In practical application, pulling the pull strap 200 out of the base 100 allows the unlocking component 310 to press down, thereby unlocking the optical module by driving the locking hook 320. After the pull strap 200 automatically resets under the elastic force of the spring 330, the reset component 410 presses down on the locking hook 320 to reset it, locking the optical module. This embodiment provides a new lever-type optical module unlocking device, which is simple in structure and easy to operate.

[0050] Referring to Figures 3 and 4, and in conjunction with Figures 5 and 6, the locking hook 320 in this embodiment includes a locking hook body 321, a locking portion 322, and a protrusion 323. The locking portion 322 protrudes from the end of the locking hook body 321; the protrusion 323 protrudes from the middle position of the upper surface of the locking hook body 321. The unlocking member 310 includes a connecting portion 312 and a pressing portion 313. The pressing portion 313 protrudes from the end of the connecting portion 312; the end of the connecting portion 312 away from the pressing portion 313 is connected to the pull strap 200; the pressing portion 313 is configured to press the protrusion 323 when the pull strap 200 is pulled out to the side away from the base 100, causing the locking portion 322 to be pressed down, thereby unlocking the optical module. That is, when the pull strap 200 is pulled away from the unlocking member 310, i.e., when the pull strap 200 is pulled out, the pressing part 313 is blocked when it is pulled to the position of the protrusion 323, and applies a downward force to the protrusion 323, pressing the protrusion and causing the locking part 322 to move downward, thereby unlocking the optical module. When no external force is applied to the pull strap 200, the pull strap 200 automatically resets, the pressing part 313 is not located at the position of the protrusion 323, and the pressing part 313 does not apply any force to the locking hook 320.

[0051] To facilitate smoother operation of the unlocking mechanism during pulling, the upper surface of the lock hook body 321 in this embodiment is an inclined plane, with the inclined plane tilting downwards towards the locking part 322. Of course, the upper surface of the lock hook body 321 can also be a horizontal plane. As long as a protrusion 323 is provided on the upper surface of the lock hook body 321, when the pull strap is pulled away from the base 100, pressing the protrusion 323 causes the locking part 322 of the lock hook body 321 to sink, thereby unlocking the optical module.

[0052] Optionally, in this embodiment, the top cover 400 and the base 100 are detachably connected.

[0053] Optionally, the top cover 400 has a U-shaped design, with slots 420 on both sides. The base 100 has a buckle 110 at its end that matches the slots 420. The top cover 400 is fixedly connected to the base 100 via the slots 420. Alternatively, slots can be provided on the base 100, and buckles can be provided on the top cover 400 to mate with the slots. The top cover 400 can then be detachably connected to the base 100 via the buckles engaging with the slots. Furthermore, the top cover 400 and base 100 can also be connected using other detachable methods such as plug-in connections or threaded fasteners, which are not limited here. Threaded fasteners can be bolts, screws, etc. The top cover 400 does not necessarily have to be U-shaped; the shape depends on the actual assembly with the optical module and the base 100. The shape and structure of the top cover 400 are not limited here.

[0054] The top of the top cover 400 is provided with a first through groove 430. The reset member 410 is disposed in the first through groove 430 and is movably connected to the top cover 400. The reset member 410 is a metal elastic sheet, which matches the first through groove 430. One side of the metal elastic sheet is fixedly connected to the first through groove 430. The other side of the elastic sheet is configured to apply downward pressure to the locking hook 320, causing the locking hook 320 to tilt upward, thereby locking the optical module. Of course, the top cover 400 may also not have the first through groove 430. The reset member 410 is provided on the side of the top cover 400 facing the base 100, and the reset member 410 can apply downward pressure to the locking hook 320. When the pull strap 200 is pulled away from the unlocking member 310, i.e., when the pull strap 200 is pulled out, the pressing part 313 is blocked when it reaches the position of the protrusion 323, and applies a downward force to the protrusion 323, pressing the protrusion and causing the locking part 322 to move downward, thereby unlocking the optical module. At the same time, the locking part 322 also loses contact with the reset member 410 and is no longer subject to the downward pressure applied by the reset member 410. When no external force is applied to the pull strap 200, the pull strap 200 automatically resets, and the locking hook 320 re-contacts the reset member 410. The reset member 410 then applies downward pressure to the locking hook 320, causing the locking hook 320 to tilt upward, thereby locking the optical module.

[0055] The unlocking member 310 has a second through groove 311 in the middle that matches the first through groove 430. The end of the locking hook 320 away from the pull strap 200 can be moved up and down through the second through groove 311. Specifically, the metal elastic sheet is preferably made of a thin sheet of stainless steel. Of course, the reset member 410 can be made of an elastic sheet, but the elastic sheet does not necessarily have to be made of metal. Other elastic materials can also be used, which are not limited here.

[0056] In practical application, as shown in Figure 3, when the pull strap 200 is pulled out, the unlocking component 310 presses down on the middle of the locking hook 320, causing the locking hook 320 to sink and unlock. At this time, the other end of the locking hook 320 pushes up the metal elastic sheet through the second through groove 311. When the pull strap 200 automatically retracts under the force of the spring 330, the end of the locking hook 320 near the pull strap 200 resets, while the end of the locking hook 320 away from the pull strap 200 resets under the force of the metal elastic sheet, thus locking the optical module. The top cover 400 in this unlocking device also serves to limit and fix the unlocking component 300 as a whole, preventing the unlocking component 300 from misaligning or shaking during operation.

[0057] Optionally, the base 100 is provided with a first mounting groove 120 that matches the locking hook 320. The first mounting groove 120 is provided with an arc-shaped protrusion 121, and the bottom of the locking hook 320 is provided with an arc-shaped groove that matches the arc-shaped protrusion 121. The locking hook 320 is rotatably connected between the arc-shaped protrusion 121 and the arc-shaped groove. Of course, a rotating shaft can also be provided in the first mounting groove 120, and the locking hook 320 can be sleeved on the rotating shaft.

[0058] The base 100 is also provided with a second mounting groove 130 that matches the spring 330. In this embodiment, there are two second mounting grooves 130, which are respectively located on both sides of the first mounting groove 120. One end of the spring 330 is fixed in the second mounting groove 130, and the other end of the spring 330 is movably connected to the unlocking member 310. The dimensions of the first mounting groove 120 and the second mounting groove 130 can be set according to actual needs, so as to fit the lock hook 320 and the spring 330. The spring 330 can be fixed to both sides of the unlocking member 310. The two springs 330 can apply a uniform force to the unlocking member 310, ensuring that the unlocking member 310 can be retracted smoothly. Of course, the number of second mounting grooves 130 can also be one, three, four, or more, which is not limited here. One or more springs 330 can also be set in the second mounting groove 130, which is set according to actual needs, which is not limited here.

[0059] Referring to Figure 5, and in conjunction with Figures 7 and 8, the unlocking component 310 in this embodiment includes a connecting portion 312 and a spring-supporting portion 314. The spring-supporting portion 314 protrudes from the end of the connecting portion 312; the end of the connecting portion 312 away from the spring-supporting portion 314 is connected to the pull strap 200; the spring-supporting portion 314 abuts against the spring 330. When the pull strap 200 is not pulled, the spring 330 is in a naturally extended state; when the pull strap 200 is pulled out, the spring 330 is in a compressed state. Therefore, when no external force is applied to the pull strap 200, the spring 330 will return to its initial state, thereby driving the pull strap 200 to reset. In this embodiment, the spring-supporting portion 314 only abuts against the spring 330, that is, it only contacts the spring 330. Of course, it can also be connected to the spring 330, which is not limited here.

[0060] Optionally, the pull strap 200 is made of plastic. To ensure the stability of the connection between the pull strap 200 and the unlocking member 310, in this embodiment, the end of the pull strap 200 near the unlocking member 310 is fixedly connected to the unlocking member 310, and the unlocking member 310 extends into the pull strap 200. The pull strap 200 can be riveted or glued to the unlocking member 310, or the pull strap 200 can be connected to the unlocking member 310 in other ways, such as plugging or welding, which is not limited here. The end of the pull strap 200 away from the unlocking member 310 is provided with a handle 210; by providing the handle 210, it is easy to control the operation of the pull strap 200, thereby easily realizing the unlocking operation of the optical module. Of course, the pull strap can also be made of other materials, depending on the actual application scenario and cost, which is not limited here.

[0061] The second aspect of this disclosure provides an optical module that includes the optical module unlocking device described in any one of the first aspects of this disclosure. The optical module provided by the second aspect of this disclosure includes the optical module unlocking device of any one of the first aspects of this disclosure, and therefore has all the beneficial effects of the optical module unlocking device of any one of the first aspects of this disclosure, which will not be repeated here.

[0062] The working principle of the optical module unlocking device provided in this embodiment is as follows:

[0063] When the pull strap 200 is pulled out, the unlocking member 310 presses down on the locking hook 320, causing the portion of the locking hook 320 that is locked to the optical module to move downward, thereby unlocking the optical module. At the same time, the locking part 322 also disconnects from the reset member 410 and is no longer subjected to the downward pressure applied by the reset member 410. When the pull strap 200 is pulled out, the unlocking member 310 applies pressure to the spring 330, compressing the spring 330, which is in a compressed state. After no force is applied to the pull strap 200, the spring 330 returns from the compressed state to its natural extended state, applying the opposite force to the pull strap 200, causing it to automatically reset. The locking hook 320 re-contacts the reset member 410, and the reset member 410 again applies downward pressure to the locking hook 320, causing the locking hook 320 to tilt upward, thereby locking the optical module.

[0064] Thirdly, embodiments of this disclosure also provide an optical module unlocking device, which includes a base 100, a pull strap 200, and an unlocking component 300. The unlocking component 300 includes an unlocking member 310, a locking hook 320, and a spring 330. The pull strap 200 is fixedly connected to the unlocking member 310, and the locking hook 320 is disposed on the base 100 and movably connected to the base 100. When the pull strap 300 is pulled out, the unlocking member 310 can press down on the locking hook 321 to configure the locking hook 321 to unlock the optical module. The spring 330 is disposed on the base 100 and is configured to automatically reset the pull strap 200 without external force after it is pulled out. At this time, the locking hook 320 is still in the unlocked state for the optical module. The optical module can be locked by setting the reset member 410 to press the locking hook 320 upward.

[0065] Specifically, in this embodiment, the locking hook 320 includes a locking hook body 321, a locking part 322, and a protrusion 323. The locking part 322 protrudes from the end of the locking hook body 321; the protrusion 323 protrudes from the middle position of the upper surface of the locking hook body 321. The unlocking member 310 includes a connecting part 312 and a pressing part 313. The pressing part 313 protrudes from the end of the connecting part 312. The end of the connecting part 312 away from the pressing part 313 is connected to the pull strap 200. The pressing part 313 is configured to press the protrusion 323 when the pull strap 200 is pulled out to the side away from the base 100, so that the locking part 322 is pressed down, thereby unlocking the optical module. That is, when the pull strap 200 is pulled away from the unlocking member 310, i.e., when the pull strap 200 is pulled out, the pressing part 313 is blocked when it is pulled to the position of the protrusion 323, and applies a downward force to the protrusion 323, pressing the protrusion and causing the locking part 322 to move downward, thereby unlocking the optical module. When no external force is applied to the pull strap 200, the pull strap 200 automatically resets, the pressing part 313 is not located at the position of the protrusion 323, and the pressing part 313 does not apply any force to the locking hook 320.

[0066] The unlocking component 310 in this embodiment also includes a spring abutment portion 314, which protrudes from the end of the connecting portion 312 where the pressing portion 313 is located; the spring abutment portion 314 abuts against the spring 330. When the pull strap 200 is not pulled, the spring 330 is in a naturally extended state; when the pull strap 200 is pulled out, the spring 330 is in a compressed state. Therefore, when no external force is applied to the pull strap 200, the spring 330 will return to its initial state, thereby driving the pull strap 200 to reset. In this embodiment, the spring abutment portion 314 only abuts against the spring 330, that is, it only contacts the spring 330.
