Description

Technical Field

[0001] This utility model relates to the field of optical module technology, and in particular to an optical module with a pull ring structure. Background Technology

[0002] An optical module is a device that can convert optical signals into electrical signals and vice versa. Optical modules are often used in conjunction with switches. The optical module is inserted into the optical cage on the switch. When unlocking, the unlocking protrusion on the pull ring on the optical module pushes the spring on the optical cage outward by a predetermined size to achieve unlocking.

[0003] Conventionally, an optical module has a spring installed between its housing and a pull ring. The spring's elasticity drives the pull ring to return to its original position after movement. However, during optical module assembly, springs are prone to being missing or improperly installed, affecting the module's usability. Furthermore, springs are small, cumbersome to assemble, time-consuming, and labor-intensive, resulting in low assembly efficiency and failing to effectively meet the assembly requirements of optical modules. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to propose an optical module with a pull ring structure, which can achieve reset after the pull ring structure has been moved without the need for a spring, simplifying the assembly steps of the overall structure, saving time and effort, and achieving high assembly efficiency of the optical module, effectively meeting the assembly requirements of the optical module, and demonstrating strong practicality.

[0005] The technical solution of this utility model is achieved as follows: an optical module with a pull ring structure, including a housing and a pull ring structure;

[0006] The pull ring structure is movably disposed on the shell along the length direction of the shell, including long arms disposed on both sides of the shell in the width direction and extending along the length direction of the shell, and a connecting part disposed on one side of the shell in the height direction and connected to the two sets of long arms.

[0007] The connecting part has a first engagement position away from the long arms corresponding to at least one set of long arms; a first elastic arm is formed on the connecting part extending from the first engagement position toward the long arms; a second elastic arm is formed by bending and extending from the end of the first elastic arm toward one side of the height direction of the shell; a stop is formed by bending and extending from the end of the second elastic arm toward the relative inner side of the two sets of long arms.

[0008] The outer wall of the housing is provided with a stop groove corresponding to the stop portion; the end of the stop portion extends into the stop groove.

[0009] Furthermore, a gap is formed between the end of the second elastic arm and the end of the first elastic arm in the length direction of the housing.

[0010] Furthermore, the long arm is provided with an extension portion extending toward the relative inner side of the two sets of long arms; the extension portion and the connecting portion are arranged on opposite sides in the height direction of the housing, and a limiting distance is formed between them.

[0011] Furthermore, a gap is formed between the opposite ends of the two sets of extensions; one of the two sets of extensions has a notch on its opposite end, and the other has an outward protrusion that is accommodated in a recess on its opposite end; the outward protrusion and the recess form a limiting fit in the extending direction of the extension.

[0012] Furthermore, the long arm has a spring end that moves in a direction close to or away from the housing and a push-pull end that moves away from the spring end; guide grooves are provided on both side walls in the width direction of the housing; the long arm slides in the guide grooves and has an unlocking position that causes the spring end to deviate outward from the housing, and a reset position that receives the spring end; the spring end of the long arm is provided with an unlocking part; the unlocking part protrudes from the side of the long arm facing away from the housing.

[0013] Furthermore, the long arm has a second engagement position away from the elastic end; a third elastic arm and a fourth elastic arm are formed side by side on the long arm, extending from the second engagement position toward the elastic end of the long arm; the unlocking part is disposed on the elastic end of the third elastic arm; the elastic end of the fourth elastic arm has a mounting platform extending outward in the width direction of the long arm; a recessed groove is provided on the side wall of the guide groove corresponding to the mounting platform; in the reset position, the mounting platform is inserted into the recessed groove; the mounting platform has a disengagement guide surface facing the push-pull end of the long arm; the disengagement guide surface extends from the fourth elastic arm toward the push-pull end away from the long arm.

[0014] Furthermore, the two sets of fourth elastic arms are arranged on opposite sides of the third elastic arm.

[0015] Furthermore, the pull ring structure includes a handle portion; the handle portion is connected to one end of the two sets of long arms on the same side.

[0016] Furthermore, the housing includes a lower shell and an upper shell that can move relative to each other in the length direction of the housing; a limiting structure is provided between the lower shell and the upper shell to restrict the upper shell from moving relative to the lower shell toward a first side in the length direction of the housing; the stop groove is provided on the lower shell or the upper shell.

[0017] Furthermore, the limiting structure includes a countersunk opening and a plug-in portion; of the lower shell and the upper shell, one end of the lower shell has a countersunk opening in the length direction, and the other end has a plug-in portion that plugs into the countersunk opening along the length direction of the shell.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0019] 1. This utility model utilizes the coordinated use of a first elastic arm, a second elastic arm, and a stop. When the pull ring structure moves relative to one end of the housing in a first direction, the stop is restricted from moving by the stop groove. The first and second elastic arms undergo elastic deformation, giving the stop a restoring force that drives the pull ring structure to move in the opposite direction, thus achieving the reset of the pull ring structure after movement. No spring is needed between the pull ring structure and the housing, simplifying the assembly steps of the overall structure, saving time and effort, increasing the assembly efficiency of the optical module, effectively meeting the assembly requirements of the optical module, and demonstrating strong practicality.

[0020] 2. Through the elastic deformation of the first elastic arm and the second elastic arm, when the stop part is pulled away from the housing, the stop part can automatically reset and insert into the stop groove, so that the pull ring structure can be smoothly inserted into the housing during the assembly process without being blocked by the stop part. The overall structure is easy and smooth to assemble and has strong practicality.

[0021] 3. In this utility model, a third and fourth elastic arms are added to the long arm, and the unlocking part is arranged on the third elastic arm. Through the cooperation of the fourth elastic arm and the mounting platform, when the long arm is inserted into the guide groove, the compression deformation of the fourth elastic arm allows the mounting platform to be inserted into the guide groove simultaneously and move with it. When the long arm moves to the reset position, the fourth elastic arm springs back to reset, allowing the mounting platform to be inserted into the recess. A limiting fit is formed between the mounting platform and the recess to stably and reliably fix the elastic end of the long arm in the guide groove, preventing the elastic end of the long arm from loosening, effectively improving the stability of the long arm installed in the guide groove, and making it highly practical.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] like Figure 1-7The diagram illustrates an optical module with a pull ring structure as described in this embodiment. This optical module is installed within a conventional optical cage. The movement of the pull ring structure 2 unlocks the optical module, allowing it to be removed from the optical cage. The optical module includes a housing 1 and a pull ring structure 2. The housing 1 has a length, width, and height. The length direction of the housing 1 is defined as a first direction. The pull ring structure 2 is mounted on the housing 1 and slides along its length. The pull ring structure 2 includes long arms 21 and a connecting portion 22. The long arms 21 are arranged on both sides of the housing 1 in the width direction and extend along the length direction of the housing 1. The width direction of the long arms 21 coincides with the height direction of the housing 1. The connecting portion 22 is a thin plate structure, arranged on one side of the housing 1 in the height direction, and connected to two sets of long arms 21, forming a single unit. The connecting portion 22 has a first engagement position corresponding to at least one set of long arms 21, away from the long arms 21. In this embodiment, this first engagement position corresponds to the arrangement of two sets of long arms 21. A first elastic arm 23 extends from the first engagement position toward the long arm 21 (i.e., the width direction of the housing 1 in this embodiment) on the connecting portion 22. The first elastic arm 23 has predictable elastic deformation capability, capable of rebounding from a position away from the housing 1 toward a position closer to the housing 2, and also has elastic torsional deformation capability. The first elastic arm 23 extends along the width direction of the housing 1. A second elastic arm 24 is formed by bending and extending from the end of the first elastic arm 23 toward one side in the height direction of the housing 1 (also the width direction of the long arm 21). The second elastic arm 24 is located on the outer side in the width direction of the housing 1. The second elastic arm 24 and the first elastic arm 23 are perpendicular to each other. The second elastic arm 24 has predictable elastic deformation capability, capable of rebounding from a position away from the housing 1 toward a position closer to the housing 1 in the width direction of the housing 1, and also has elastic torsional deformation capability. A clearance opening 292 is machined on the long arm 21. The second elastic arm 24 is accommodated within the clearance opening 292. A stop portion 25 is formed by bending and extending from the end of the second elastic arm 24 toward the relative inner sides of the two sets of long arms 21. The bending angle is 90°. Through the above structural design, the stop portion 25 has a rebound force in the length direction of the housing 1 and a rebound force in the width direction of the housing 1. A stop groove 13 is machined on the outer wall of the aforementioned housing 1 corresponding to the stop portion 25. The stop groove 13 has a length extending along the length direction of the housing 1, and its two ends are closed. The end of the aforementioned stop portion 25 extends into the stop groove 13. When the pull ring structure 2 moves toward one end in the length direction of the housing 1, the stop portion 25 is limited to one end of the stop groove 13 to restrict its movement. The first elastic arm 23 and the second elastic arm 24 generate elastic deformation, so that the stop portion 25 generates a rebound force to drive the pull ring structure 2 to move in the opposite direction, thereby realizing the reset of the pull ring structure 2 after movement.

[0033] In this embodiment, the aforementioned long arm 21 is a thin plate structure, having a spring end that moves in a direction close to or away from the housing 1 (i.e., the width direction of the housing 1) and a push-pull end away from the spring end. The aforementioned connecting portion 22 is arranged close to the push-pull end of the long arm 21. In a specific structural design, a gap is formed between the end of the second spring arm 24 and the end of the first spring arm 23 in the length direction of the housing 1. Specifically, the end of the second spring arm 24 is closer to the push-pull end of the long arm 21 than the end of the first spring arm 23, in order to improve the rebound force acting on the pull ring structure 2.

[0034] In this embodiment, extension portions 29 are respectively arranged on the two sets of long arms 21, extending towards the relatively inward sides of the two sets of long arms 21. The height direction of the housing 1 is defined as the vertical direction. The extension portion 29 is located below the housing 1. A limiting gap is formed between the extension portion 29 and the connecting portion 22. The housing 1 can be positioned within this limiting gap at its upper limit in the height direction to improve the stability of the pull ring structure 2 mounted on the housing 1.

[0035] The aforementioned long arm 21, connecting portion 22, and extension portion 29 are integrally formed. In specific processing, the long arm 21 is formed by bending downwards from both ends of the connecting portion 22 in the same direction, and the extension portion 29 is formed by bending and extending from the bottom side of the long arm 21. A gap is formed between the opposite ends of the two sets of extension portions 29. One set of extension portions 29 has a notch machined on its opposite end, while the other set has an outwardly protruding portion 291 that is accommodated in a recess. The outwardly protruding portion 291 and the recess form a limiting fit in the extending direction of the extension portion. This mutual limiting fit between the outwardly protruding portion 291 and the recess enhances the strength of the pull ring structure 2.

[0036] The pull ring structure 2 of this embodiment includes a handle portion 28. The handle portion 28 has a U-shaped structure. Both ends of the handle portion 28 are connected to one end of the same side of the two sets of long arms 21, respectively. By gripping the handle portion 28 and pushing or pulling, the handle portion 28 can be moved along a first direction.

[0037] In this embodiment, the aforementioned housing 1 includes a lower housing 11 and an upper housing 12 that are movable relative to each other in a first direction. A cavity is formed between the lower housing 11 and the upper housing 12 to accommodate the components of the optical module. A limiting structure is arranged between the lower housing 11 and the upper housing 12 to restrict the upper housing 12 from moving relative to the lower housing 11 towards a first side in the first direction. By limiting the movement of the lower housing 11 and the upper housing 12 during assembly, pre-positioning of the lower housing 11 and the upper housing 12 can be achieved, thereby improving assembly efficiency. Specifically, one of the lower housing 11 and the upper housing 12 has a countersunk opening 15 at one end in the first direction, and the other has a plug-in portion 16 machined on it. During the assembly of the upper housing 12 and the lower housing 11, the plug-in portion 16 is inserted into the countersunk opening 15 along the first direction, and the plug-in portion 16 abuts against the bottom of the countersunk opening 15 or the upper housing 12 and the lower housing 11, thereby achieving pre-positioning between the upper housing 12 and the lower housing 11. The aforementioned stop groove 13 is arranged on the lower shell 11 or the upper shell 12.

[0038] In this embodiment, a second engagement position is arranged on the aforementioned long arm 21, and a third elastic arm 26 and a fourth elastic arm 27 extend from the second engagement position to the elastic end of the long arm 21 in parallel formation. An unlocking part 261 that cooperates with the optical cage is installed on the elastic end of the third elastic arm 26. Guide grooves 14 are machined on the side walls of opposite sides of the housing 1. The aforementioned two sets of long arms 21 slide within the guide grooves 14 on their respective sides, having an unlocking position that causes the elastic end to deviate outward from the housing 1, and a reset position that accommodates the elastic end. In the unlocking position, the unlocking part 27 cooperates with the optical cage to lift the spring piece on the optical cage, thereby unlocking the optical module. In the reset position, both the long arm 21 and the unlocking part 27 are hidden within the guide groove 14, allowing the optical module to be smoothly inserted into the optical cage. The specific structure of the aforementioned guide groove 14 is prior art, comprising a straight section in its extension direction, a recessed section, and a transition section connecting the straight section and the recessed section. When the elastic end of the long arm 21 moves from the sinking section to the straight section, the elastic end of the third elastic arm 26 is guided to deviate to the outside of the guide groove 14 so as to make contact with the spring sheet on the optical cage.

[0039] The fourth elastic arm 27 has a mounting platform 271 extending outward in the width direction of the long arm 21, mounted on its elastic end. A recessed groove 17 is machined on the side wall of the guide groove 14 corresponding to the mounting platform 271. When the long arm 21 is inserted into the guide groove 14, the compression deformation of the fourth elastic arm 27 allows the mounting platform 271 to be inserted into the guide groove 14 synchronously and move accordingly. When the long arm 21 moves to the reset position, the fourth elastic arm 27 springs back to its reset position, allowing the mounting platform 271 to be inserted into the recessed groove 17. A limiting fit is formed between the mounting platform 271 and the recessed groove 17 to stably and reliably fix the elastic end of the long arm 21 within the guide groove 14, preventing the elastic end of the long arm 21 from loosening and effectively improving the stability of the long arm 21 installed within the guide groove 14. The mounting platform 271 has a release guide surface 272 facing the push-pull end of the long arm 21. The disengagement guide surface 272 extends from the fourth elastic arm 27 toward the push-pull end away from the long arm 21. In this embodiment, the disengagement guide surface 272 can be a sloped structure. When the long arm 21 moves from the reset position to the unlocked position, guided by the disengagement guide surface 272, the mounting platform 271 can disengage from the recess 17. The two sets of fourth elastic arms 27 are arranged on opposite sides of the third elastic arm 26.

[0040] During assembly, the stop 25 is pulled outward from the opposite sides of the two sets of long arms 21, inserting the long arms 21 into the guide grooves 14 on the housing 1. Releasing the stop 25 allows it to automatically reset and insert into the stop groove 13, and the mounting platform 271 is inserted into the recess 17. In use, the handle 28 is gripped to pull the pull ring structure 2 relative to the housing 1 towards one end in the first direction. The unlocking part 27 on the third elastic arm 26 engages with the optical cage to lift the spring on the optical cage, thereby unlocking the optical module. Simultaneously, the stop 25 is restricted from movement by the stop groove 13, and the first elastic arm 23 and the second elastic arm 24 undergo elastic deformation, giving the stop 25 a rebound force that drives the pull ring structure 2 to move in the opposite direction. When the grip is released, the pull ring structure 2 automatically resets under the action of the rebound force. In the above method, the pull ring structure 2 can be smoothly inserted into the housing 1 during the assembly process without being blocked by the stop part 25. The overall structure is easy and smooth to assemble. No spring is needed between the pull ring structure 2 and the housing 1, which simplifies the assembly steps of the overall structure, saves time and effort, and has high assembly efficiency of optical modules. It effectively meets the assembly requirements of optical modules and has strong practicality.
