Description

Technical Field

[0001] This invention relates to the field of optical communication equipment technology, and in particular to unlocking mechanisms, optical module packaging, and unlocking methods. Background Technology

[0002] Optical modules are one of the core components of fiber optic communication systems, used to convert between optical signals and electrical signals. Both the communications and AI industries have increasingly higher demands for optical modules, and at the same time, they also require higher data rate density. High data rate density refers to the relationship between the data rate of an optical module and the space it occupies; the higher the data rate, the smaller the space required, and the higher the data rate density.

[0003] The speed of an optical module is primarily determined by the chips housed within it. However, due to limitations in chip technology and cost, current methods mainly increase the speed by increasing the number of channels, which leads to a larger package size. For 16-channel optical modules, the CDFP package employs a dual-circuit board structure, allowing 16 optical and electrical channels to be placed in a very small space, effectively improving the high-speed density of the 16-channel optical module.

[0004] However, the current unlocking mechanism of CDFP packaged products uses the elastic deformation capability of sheet metal to lock or unlock the hook and the socket cage. After long-term use, the elastic deformation will turn into plastic deformation, causing the locking function to fail. Summary of the Invention

[0042] To achieve this objective, the embodiments of the present invention adopt the following technical solutions:

[0044] The locking hook is rotatably mounted on the packaging body;

[0045] A pull ring assembly is slidably mounted on the encapsulation body;

[0046] The end of the pull ring assembly abuts against the locking hook;

[0047] The pull ring assembly has a first position and a second position;

[0048] When the pull ring assembly is in the first position, the locking hook is locked to the insertion cage;

[0057] To achieve this objective, the embodiments of the present invention adopt the following technical solutions:

[0058] An unlocking method, the method being applied to the aforementioned optical module encapsulation;

[0059] The method includes:

[0060] The pull ring assembly is moved along the first direction, and the locking hook rotates along the first rotation direction, causing the locking hook to disengage from the insertion cage;

[0064] Optionally, the method further includes:

[0065] The reset component resets, driving the pull ring assembly to move along the second direction.

[0066] The technical solution provided by this invention involves setting the end of the pull ring assembly to abut against the locking hook. This abutment converts the movement of the pull ring assembly into the rotation of the locking hook. Therefore, when a moving force is applied to the pull ring assembly to switch between a first position and a second position, the locking hook can be driven to switch between a locked and unlocked state with the insertion cage. This method is simple to operate. Furthermore, the rotational locking or unlocking mechanism ensures strong locking stability and a long service life. Attached Figure Description

[0077] Typically, the unlocking mechanism of a CDFP package includes a metal locking tab and a pull ring connected to the end of the locking tab away from the socket cage. The locking end of the locking tab, which locks with the socket cage, has a locking hook facing the socket cage. When a pulling force is applied to the pull ring away from the CDFP package, the locking end of the locking tab elastically deforms under the constraint of the CDFP package body, causing the locking hook to bend upwards, thereby unlocking the socket cage. After prolonged use, the elastic deformation of the locking end will turn into plastic deformation, causing the locking function to fail.

[0078] Based on this, the inventors of this application attempted to solve the above problems by using a rotation locking and unlocking method. The locking hook is rotatably set on the encapsulation body, and a cooperative structure that links the locking hook and the pull ring is used to convert the movement or rotation of the pull ring into the rotation of the locking hook, thereby achieving the purpose of easy operation for unlocking or locking, and strong locking reliability. Thus, the following embodiments are obtained.

[0079] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0080] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0081] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0082] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0083] This application provides an optical module package, which can be any type of package, such as CDFP, QSFP, SFP, XFP, CFP, OSFP-XD, etc. The optical module package of this application can be stably inserted into the socket cage and locked, and is easy to operate and unlock.

[0084] For details, please refer to Figures 1-3 As shown in some embodiments of this application, one feasible structure for optical module encapsulation includes an encapsulation body 2 and an unlocking mechanism 1. The encapsulation body 2 has multiple optical and electrical channels. The encapsulation body 2 is pluggable into the socket cage to enable electrical signal communication between the optical module inside the encapsulation body 2 and the host. The unlocking mechanism 1 includes a locking hook 11 rotatably disposed on the encapsulation body 2 and a pull ring assembly 12 slidably disposed on the encapsulation body 2. The end of the pull ring assembly 12 abuts against the locking hook 11. The pull ring assembly 12 has a first position and a second position. When the pull ring assembly 12 is in the first position, the locking hook 11 is locked to the socket cage. When the pull ring assembly 12 is in the second position, the locking hook 11 is unlocked from the socket cage. The abutment between the end of the pull ring assembly 12 and the locking hook 11 can convert the movement of the pull ring assembly 12 into the rotation of the locking hook 11. Therefore, when a moving force is applied to the pull ring assembly 12 to switch between the first position and the second position, the locking hook 11 can be driven to switch between the locked state and the unlocked state with the socket cage, which is simple to operate. Furthermore, the locking mechanism utilizes the rotating hook 11 to engage with the socket cage for locking or to detach from the socket cage for unlocking, resulting in strong locking stability and a long service life. The locking hook 11 can be rotatable in two ways: either the package body 2 has a rotating shaft 111 on which the locking hook 11 is sleeved, or the locking hook 11 has coaxial and protruding rotating shafts 111 on both sides, with the rotating shafts 111 inserted into corresponding shaft holes on the package body 2 and able to rotate relative to the shaft holes.

[0085] Furthermore, in some embodiments of this application, please refer to Figures 1-3As shown, the pull ring assembly 12 has a first inclined surface 1212 at its end. The locking hook 11 has a hook end at one end, which can hook the insertion cage, and an abutment end at the other end, which has an abutment groove. The groove wall facing the pull ring assembly 12 is a second inclined surface 1121, which abuts and matches the first inclined surface 1212. The groove wall facing away from the pull ring assembly 12 is a second abutment surface 1122. The end face of the pull ring assembly 12 is a first abutment surface 1213, which abuts and matches the second abutment surface 1122, so as to convert the moving power of the pull ring assembly 12 into the rotational power of the locking hook 11. During the movement of the pull ring assembly 12 toward the remote locking hook 11, relative movement occurs between the first inclined surface 1212 and the second inclined surface 1121, and the inclined surfaces guide the displacement. During this process, because the pull ring assembly 12 is restricted by the encapsulation body 2, it only has one degree of freedom—movement along the encapsulation body 2. Therefore, as the pull ring assembly 12 moves, such as... Figure 3 As shown, the first inclined plane 1212 applies a force F perpendicular to the second inclined plane 1121. This force F can be decomposed into a downward vertical force F1 and a force F2 along the moving direction of the pull ring assembly 12. Under the action of F1, the locking hook 11 rotates clockwise, thus switching from a state of hooking the socket cage to a state of separation from the socket cage. When a force is applied to the pull ring assembly 12 to move towards the locking hook 11, after the first abutting surface 1213 abuts against the second abutting surface 1122, the first abutting surface 1213 applies a pushing force to the second abutting surface 1122 towards the locking hook 11, causing the locking hook 11 to rotate counterclockwise, thus locking the hook end to the socket cage.

[0086] Specifically, in some embodiments of this application, please refer to Figures 1-3 As shown, the first inclined surface 1212 is located below the end of the pull ring assembly 12, and the abutment groove is located above the locking hook 11 away from the insertion cage. Both the first inclined surface 1212 and the second inclined surface 1121 slope upwards from the locking hook 11 to the pull ring assembly 12. Please refer to... Figure 3 As shown, when the pull ring assembly 12 is pulled away from the locking hook 11, F1 is vertically downward, and the locking hook 11 rotates clockwise, unlocking the socket cage. In the unlocked state, the angle of the second abutment surface 1122 has changed compared to the locked state. Therefore, when the pull ring assembly 12 moves towards the locking hook 11, after the first abutment surface 1213 contacts the second abutment surface 1122, the force P applied by the first abutment surface 1213 to the second abutment surface 1122 will be divided into a component force P1 perpendicular to the second abutment surface 1122 and a component force P2 parallel to the second abutment surface 1122. Under the action of P1, the locking hook 11 rotates counterclockwise, hooking the socket cage to achieve locking.

[0087] It is understandable that when the locking hook 11 is in the locked state with the socket cage, if the encapsulation body 2 is subjected to an external impact or the pull ring assembly 12 is accidentally triggered, the locking hook 11 may be unlocked from the socket cage. To avoid this problem, please refer to some embodiments of this application. Figure 3 As shown, the unlocking mechanism 1 also includes a reset member 14. One end of the reset member 14 is connected to the encapsulation body 2, and the other end is connected to the pull ring assembly 12. When the reset member 14 is compressed or stretched, it generates a reset force. When the pull ring assembly 12 is in the second position, the reset force of the reset member 14 is the second reset force; when the pull ring assembly 12 is in the first position, the reset force of the reset member 14 is the first reset force. The second reset force is greater than the first reset force. That is, when the lock hook 11 is unlocked from the socket cage, the reset member 14 generates a second reset force; when the lock hook 11 is locked to the socket cage, the reset member 14 generates a first reset force. When the lock hook 11 switches from the locked state to the unlocked state, the reset member 14 needs to be compressed or stretched, causing the reset force inside the reset member 14 to increase from the first reset force to the second reset force. During this process, when the pull ring is pulled from the first position to the second position, it needs to overcome the continuously increasing reset force of the reset member 14 to achieve unlocking. Therefore, if the encapsulation body 2 is accidentally impacted by an external force or the pull ring assembly 12 is accidentally touched, it will not cause the locking hook 11 to unlock from the socket cage, ensuring stable locking. When the optical module encapsulation is inserted into the socket cage, the pull ring assembly 12 needs to be pulled to the second position. After the optical module encapsulation is inserted into the socket cage, the pull ring assembly 12 is released. Under the action of the second reset force of the reset member 14, the pull ring assembly 12 automatically switches from the second position to the first position, realizing automatic locking and facilitating operation. The reset member 14 can be a spring or an elastic rubber block. Of course, the reset member 14 can also be a torsion spring. When the reset member 14 is a torsion spring, the reset member 14 is sleeved on the rotating shaft 111 of the locking hook 11, with one end abutting against the locking hook 11 and the other end abutting against the encapsulation body 2. As long as the reset function can be realized and stable locking can be maintained, this application does not make specific limitations.

[0088] Furthermore, in some embodiments of this application, please refer to Figure 1 As shown, the pull ring assembly 12 has a transparent receiving groove 123, and the package body 2 has a connecting post 22. One end of the connecting post 22 passes through the receiving groove 123. One end of the reset member 14 is connected to the connecting post 22, and the other end abuts against the groove wall at the other end of the receiving groove 123. Placing the reset member 14 in the middle of the pull ring assembly 12 saves space compared to placing it at both ends, thereby reducing the space occupied by the optical module package in the length direction. Placing the reset member 14 in the receiving groove 123 on the pull ring assembly 12 also saves space in the height direction of the optical module package, thus making the optical module package smaller in size.

[0089] In some embodiments of this application, the unlocking mechanism 1 further includes a cover plate 13, which covers the pull ring assembly 12. A groove 21 is provided between the cover plate 13 and the encapsulation body 2, and the pull ring assembly 12 passes through the groove 21. This ensures the stability of the sliding of the pull ring assembly 12, avoids external influences, and guarantees the service life of the pull ring assembly 12. The cover plate 13 is screwed to the encapsulation body 2 by screws 1514. In addition, the cover plate 13 can also limit the extreme position of the movement of the pull ring assembly 12, prevent the pull ring assembly 12 from overtraveling, and ensure the safety of the unlocking mechanism 1.

[0090] Specifically, in some embodiments of this application, please refer to Figures 1-3 As shown, the pull ring assembly 12 includes an unlocking component 121 and an operating ring 122 connected in sequence. A first limiting groove 131 is provided on the side of the cover plate 13 opposite to the operating ring 122. The unlocking component 121 has a slider 1211 that matches the first limiting groove 131. The groove wall of the first limiting groove 131 opposite to the locking hook 11 is a first limiting wall 1311. When the pull ring assembly 12 is in the first position, the slider 1211 moves away from the first limiting wall 1311. When the pull ring assembly 12 is in the second position, the slider 1211 abuts against the first limiting wall 1311. The first limiting wall 1311 can restrict the pull ring assembly 12 from moving away from the locking hook 11, preventing the pull ring assembly 12 from slipping out of the groove 21. The end of the operating ring 122 connected to the unlocking member 121 is provided with a boss 1221. The encapsulation body 2 is provided with a lower limiting groove 23 that matches the boss 1221. The cover plate 13 is provided with an upper limiting groove 132 that matches the boss 1221. The lower limiting groove 23 and the upper limiting groove 132 are separated from the groove wall of the operating ring 122 by a second limiting wall 231. When the pull ring assembly 12 is in the first position where the lock hook 11 is locked, the boss 1221 abuts against the second limiting wall 231. When the pull ring assembly 12 is in the second position where the lock hook 11 is unlocked, the slider 1211 moves away from the second limiting wall 231. The second limiting wall 231 can limit the extreme position of the pull ring assembly 12 moving toward the lock hook 11, preventing the unlocking member 121 of the pull ring assembly 12 from applying any force other than F to the lock hook 11, thus ensuring the safety between the unlocking member 121 and the lock hook 11. In addition, the first reset force is greater than or equal to 0, which further prevents the lock hook 11 from being unlocked by non-human factors. The second limiting wall 231 can ensure that when the locking hook 11 is in the locked state, the pull ring assembly 12 is in the first position, and the first reset force is greater than 0, the pull ring assembly 12 continues to move toward the locking hook 11.

[0091] Please refer to Figure 1As shown, to ensure the movement of the pull ring assembly 12, the upper limit groove 132 and the lower limit groove 23 are open on the side opposite to the locking hook 11 to allow the pull ring assembly 12 to pass through. The boss 1221 is circumferentially surrounding the end of the unlocking ring to ensure that the second limiting wall 231 can provide a stable limiting force to the pull ring assembly 12. In some embodiments of this application, the unlocking member 121 and the operating ring 122 can be integrally formed, which saves assembly steps and provides strong connection stability. Alternatively, they can be separate components, in which case the unlocking member 121 and the operating ring 122 can be made of different materials or the same material. The separate operating ring 122 assembly makes the processing of the unlocking member 121 and the operating ring 122 more convenient. The unlocking member 121 and the operating ring 122 can be connected by at least one of the following methods: screw connection, adhesive bonding, or snap-fit ​​connection. This application does not specifically limit this method.

[0092] Furthermore, in some embodiments of this application, please refer to Figure 1 As shown, the operating ring 122 has a ring-shaped handle 1222 on the side opposite to the locking hook 11. When the operator moves the operating ring assembly 12 from the first position to the second position, he / she can put his / her finger into the handle 1222 and apply a pulling force in the direction opposite to the encapsulation body 2 to facilitate the unlocking operation.

[0093] In some other embodiments of this application, an unlocking component is also provided. Unlike the above embodiments, the pull ring component 12 on the unlocking component of this embodiment is rotatably disposed on the encapsulation body 2. The first position and the second position of the pull ring component 12 are at different angles. The pull ring component 12 is provided with a first bevel gear, and the lock hook 11 is provided with a second bevel gear. The first bevel gear and the second bevel gear mesh to switch the rotation of the pull ring component 12 to the rotation of the lock hook 11, thereby realizing the locking or unlocking of the lock hook 11 and the lock cage.

[0094] It should be noted that the unlocking mechanism 1 of this application can be used as a separate mechanism on other plug-in structures besides optical module packaging, such as USB flash drive interface, high-definition data cable interface, etc. This application does not make specific limitations.

[0095] Please refer to Figures 1-3 As shown, based on the above-described optical module encapsulation, this application embodiment also provides an unlocking method, including:

[0096] The pull ring assembly 12 is moved along the first direction, and the locking hook 11 rotates along the first rotation direction, causing the locking hook 11 to disengage from the insertion cage.

[0097] Move the pull ring assembly 12 along the second direction, and the locking hook 11 rotates along the second rotation direction, locking the locking hook 11 with the insertion cage;

[0098] The first direction is opposite to the second direction, and the first rotation direction is opposite to the second rotation direction.

[0099] In the above embodiment, the first direction is the direction away from the encapsulation body 2, and the first rotation direction is clockwise. That is to say, if the lock hook 11 is to be unlocked, the pull ring assembly 12 needs to be pulled in the direction away from the encapsulation body 2. Pulling the pull ring assembly 12 to unlock the lock hook 11 is also the simplest operation method.

[0100] Furthermore, in some embodiments of this application, the unlocking method further includes:

[0101] The reset component 14 is reset, driving the pull ring assembly 12 to move along the second direction.

[0102] When the locking hook 11 is locked, it achieves automatic locking and can be stably maintained in the locked state under the action of the reset member 14, so as to obtain stable locking performance.

[0103] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
