Description

Technical Field

[0001] The present invention relates to the technical field of optical modules, and in particular to an optical module unlocking device. Background Art

[0002] Optical modules can convert optical signals into electrical signals. Their main function is to convert electrical signals into optical signals at the transmitting end. They are widely used in the field of optical fiber communications.

[0003] The optical module needs to be locked and unlocked by a locking structure to ensure the stability of the optical module during operation; the traditional locking device is an elastic buckle, which can be deformed under the action of external force. After pushing the optical module to move to a predetermined position in the first locking sleeve, the elastic buckle unfolds and cooperates with the groove on the inner wall of the first locking sleeve to complete the locking limit; during the unlocking process of the traditional structure, the staff needs to hold the optical module and the first locking sleeve from both sides respectively, and apply opposite direction forces to the optical module and the first locking sleeve to achieve the removal and unlocking of the optical module; the traditional locking method and unlocking method rely on the strength of the elastic buckle structure. When the size and strength of the elastic buckle deviate or the elastic buckle is aged and damaged during long-term use, the optical module will be unable to be locked or unlocked, affecting the normal plug-in and replacement of the optical module and the normal use of the optical module.

[0004] In addition, there is another locking and unlocking structure on the market; it locks and limits the optical module through a rotatable pull ring structure. During the locking process, the pull ring structure is rotated to the locking position, so that the optical module and the first locking sleeve can be locked and limited, thereby realizing the normal transmission of the photoelectric signal; during the unlocking process, the pull ring structure is rotated to the unlocking position, so that the locking and limiting relationship between the optical module and the first locking sleeve can be cancelled, so as to realize the smooth plugging and unplugging of the optical module; however, the above structure also relies on the mechanical locking method between the materials for locking and limiting. After the locking part is aged and damaged, there is still a problem of inability to effectively lock and unlock, and the overall structure is placed on the outside, which is easy to be damaged and the unlocking is stuck.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0033] See attached Figure 1 -Attached Fig.12 The optical module unlocking device includes a first locking sleeve 200, a first accommodating chamber for accommodating the optical module 100 is formed inside the first locking sleeve 200, and a locking device for limiting the position of the optical module 100 is installed in the first accommodating chamber. The optical module 100 can be locked and limited by the locking device to ensure the stability of the locked installation of the optical module 100 in the first locking sleeve 200, and to ensure the normal conversion and transmission of the photoelectric signal.

[0034] See attached Figure 1The conventional locking device is an elastic buckle 110, which can be deformed under the action of external force. After pushing the optical module 100 to move to a predetermined position in the first locking sleeve 200, the elastic buckle 110 unfolds and cooperates with the groove on the inner wall of the first locking sleeve 200 to complete the locking limit. In the process of unlocking the conventional structure, the staff needs to hold the optical module 100 and the first locking sleeve 200 from both sides respectively, and apply opposite direction forces to the optical module 100 and the first locking sleeve 200 to realize the removal and unlocking of the optical module 100. The conventional locking method and unlocking method rely on the strength and strength of the elastic buckle 110 structure. When the size and strength of the elastic buckle 110 deviate or the elastic buckle 110 is aged and damaged during long-term use, the optical module 100 may be unable to be locked or unlocked, which affects the normal plug-in and replacement of the optical module 100 and the normal use of the optical module 100.

[0035] In addition, there is another locking and unlocking structure on the market; it locks and limits the optical module 100 through a rotatable pull ring structure. During the locking process, the pull ring structure is rotated to the locking position, so that the optical module 100 and the first locking sleeve 200 can be locked and limited, thereby realizing the normal transmission of the photoelectric signal; during the unlocking process, the pull ring structure is rotated to the unlocking position, so that the locking and limiting relationship between the optical module 100 and the first locking sleeve 200 can be cancelled, so as to realize the smooth plugging and unplugging of the optical module 100; however, the above structure also relies on the mechanical locking method between the materials for locking and limiting. After the locking part is aged and damaged, there is still a problem of inability to effectively lock and unlock, and the overall structure is placed on the outside, which is easy to be damaged and the unlocking is stuck.

[0036] In order to solve the above-mentioned unlocking problem, the optical module unlocking device also includes a second locking sleeve 300, and a second accommodating chamber for accommodating the first locking sleeve 200 is formed inside the second locking sleeve 300. The first locking sleeve 200 is slidably connected to the inner wall of the second accommodating chamber. The locking device includes a hydraulic locking assembly 230 located in the first accommodating chamber, and a hydraulic control device 400 connected to the hydraulic locking assembly 230 is also provided in the second accommodating chamber. A control workpiece 310 for controlling the conduction state of the hydraulic control device 400 is installed on the outer wall of the second locking sleeve 300; wherein, the hydraulic control device 400 is in the conduction state and the stroke is compressible, that is, the hydraulic control device 400, in the conduction state, can squeeze the hydraulic control device 400 in the process of pushing the first locking sleeve 200 to move toward the second accommodating chamber, and squeeze the control medium in the hydraulic control device 400 into the hydraulic locking assembly 230, so that the hydraulic locking assembly 230 is transformed into a protruding locking state, and then the optical module 100 is locked and limited, thereby ensuring the stability of the locking and limiting of the overall structure.

[0037] During the unlocking process, the locking steps can be performed in the opposite manner. First, the optical module 100 and the first locking sleeve 200 are controlled to move synchronously toward the outside. During this process, the control medium in the hydraulic locking assembly 230 enters the hydraulic control device 400. During this process, the hydraulic locking assembly 230 is transformed into a retracted unlocking state, and the restriction of the hydraulic locking assembly 230 on the optical module 100 disappears. After the first locking sleeve 200 and the optical module 100 move to the outermost position, the restriction of the hydraulic locking assembly 230 on the optical module 100 completely disappears, and the optical module 100 and the first locking sleeve 200 are in an unlimited free plug-in and pull-out state. The staff can easily pull the optical module 100 out of the first locking sleeve 200 to achieve unlocking and pulling out of the optical module 100.

[0038] It should be noted that the control medium is preferably a control oil, and the control oil is closed and flows between the hydraulic control device 400 and the hydraulic locking assembly 230, so as to realize locking and unlocking control; and in the process of locking operation, the hydraulic control device 400 is first controlled to be in a closed state, at which time the first locking sleeve 200 cannot move inward under the limit of the hydraulic control device 400. In this process, the optical module 100 can be freely and unrestrictedly inserted into the first accommodation chamber of the first locking sleeve 200 (at this stage, the optical module 100 can be plugged and unplugged to determine whether the optical module 100 can normally perform photoelectric conversion). After the preliminary plug-in and unplug test of the optical module 100 is completed, the hydraulic control device 400 can be controlled to be in a conducting state. At this time, the staff continues to push the first locking sleeve 200 and the optical module 100 from the outside to move synchronously inward. In this process, the control oil in the hydraulic control device 400 is squeezed into the hydraulic locking assembly 230, and the hydraulic locking assembly 230 changes to a protruding locking state, thereby completing the locking limit of the optical module 100.

[0039] In summary, by setting the above-mentioned structure, the optical module 100 can be subjected to a preliminary plug-in and pull-out test, thereby improving the efficiency of the optoelectronic test of the optical module 100; at the same time, after the preliminary test of the optical module 100 is completed, in the process of pushing the first locking sleeve 200 and the optical module 100 to continue to move inward, the optical module 100 can be locked and limited from the outside through the hydraulic locking assembly 230, and during the locking, limiting and unlocking process of the hydraulic locking assembly 230, the position between the hydraulic locking assembly 230 and the optical module 100 remains relatively unchanged, and the hydraulic locking assembly 230 and the optical module 100 can be locked and unlocked stably for a long time, thereby meeting the demand for high-frequency plug-in and pull-out of the optical module 100.

[0040] Please refer to the attached Fig.11Specifically, the hydraulic locking assembly 230 includes a hydraulic locking base 231 fixedly connected to the inner wall of the first accommodating chamber, a hydraulic telescopic end 232 is provided on the side wall of the hydraulic locking base 231, and a hydraulic locking block 234 is fixedly connected to the hydraulic telescopic end 232, and a guide rod 233 is fixed to the side wall of the hydraulic locking block 234, and the guide rod 233 penetrates the hydraulic locking base 231 and is slidably connected thereto, and a locking buckle 130 adapted to the hydraulic locking block 234 is fixed to the side wall of the optical module 100, and a control chamber connected to the hydraulic control device 400 is provided in the hydraulic locking base 231. After the control oil enters the control chamber, the hydraulic locking block 234 can be pushed to move toward the outside, and the hydraulic locking block 234 can be clamped with the locking buckle 130 on the side wall of the optical module 100 after being extended, so as to finally realize the locking and limiting of the optical module 100.

[0041] During the process of the first locking sleeve 200 and the optical module 100 moving synchronously toward the outside, the hydraulic control device 400 is gradually reset. During this process, the oil is controlled to flow back into the hydraulic control device 400. During this process, the hydraulic locking block 234 shrinks toward the inside, and the hydraulic locking block 234 is offset from the moving path of the locking buckle 130. At this time, the optical module 100 can be freely and unrestrictedly pulled out of the first locking sleeve 200, realizing lossless unlocking and plugging.

[0042] Furthermore, the locking buckle 130 is detachably connected to the side wall of the optical module 100, and the locking buckle 130 includes a first locking portion 131 inclined toward a first direction, and a second locking portion 132 inclined toward a second direction, the length of the first locking portion 131 is greater than the second locking portion 132, a first angle formed between the first locking portion 131 and the optical module 100 is smaller than a second angle formed between the second locking portion 132 and the optical module 100, and the first locking portion 131 is close to one side of the second accommodating chamber.

[0043] The side wall of the hydraulic locking block 234 here is concave, and its shape is adapted to the first locking part 131 and the second locking part 132. Through the above-mentioned structural design, the contact area between the hydraulic locking block 234 and the locking buckle 130 can be extended, and the strength and effect of the locking and limiting of the locking buckle 130 can be enhanced, thereby ensuring the stability of the locking and limiting of the optical module 100; at the same time, during the unlocking process, the hydraulic locking block 234 can be detached from the moving path of the locking buckle 130, avoiding interference between the locking buckle 130 and the hydraulic locking block 234, thereby facilitating the unlocking and removal of the optical module 100.

[0044] Please refer to the attached Figure 7 and attached Fig.10; The first accommodating chamber includes a left side wall and a right side wall which are arranged horizontally, and also includes an upper side wall and a lower side wall which are arranged vertically. The hydraulic locking assembly 230 is arranged in two groups, and the two groups of hydraulic locking assemblies 230 are respectively fixedly connected to the left side wall and the right side wall. Through the above-mentioned structural design, the hydraulic locking assembly 230 can extend from both sides toward the middle, and lock and limit the optical module 100 from the positions on both sides, further ensuring the stability of the locking and limiting of the optical module 100. At the same time, the locking and limiting strokes on both sides can be shortened. At this time, the hydraulic locking block 234 can be detached from the moving path of the locking buckle 130 more quickly, further facilitating the quick and lossless unlocking and removal of the optical module 100.

[0045] Please refer to the attached Figure 4 , Attachment Figure 6 , Attachment Figure 8 and attached Fig. 9 ; In order to further enhance the locking effect of the optical module 100, the locking device here also includes a mechanical locking block 220 fixedly connected to the lower side wall of the first accommodating chamber, and the side wall of the optical module 100 is installed with a clamping buckle 120 adapted to the mechanical locking block 220, and the clamping buckle 120 is elastic. A clamping rod 320 for controlling the clamping buckle 120 to become a bent state is fixed on the inner wall of the second accommodating chamber, and a notch 210 is opened on the side wall of the first locking sleeve 200 for the clamping rod 320 to pass through.

[0046] When the optical module 100 is fully inserted into the first locking sleeve 200 and the first locking sleeve 200 moves synchronously toward the second locking sleeve 300, the clamping rod 320 is located on the moving path of the clamping buckle 120. When the optical module 100 and the first locking sleeve 200 move, the clamping buckle 120 is elastically bent under the action of the clamping rod 320 and bent to the adjacent Fig. 9 In the state shown, at this time, the inner side of the clamping buckle 120 is limited by the clamping rod 320, and the outer side of the clamping buckle 120 is limited by the mechanical locking block 220, and both sides of the clamping buckle 120 are in a locked state, further ensuring the stability of the locking and limiting state of the optical module 100.

[0047] During the unlocking process, the optical module 100 and the first locking sleeve 200 move outward synchronously. At this time, the limit of the clamping rod 320 on the clamping buckle 120 disappears, and the clamping buckle 120 returns to its initial flat state. After the clamping buckle 120 returns to its flat state, the limit of the mechanical locking block 220 on the clamping buckle 120 also disappears, and the optical module 100 can be unlocked and removed freely and without restriction. During the unlocking and removal process of the optical module 100, the bottom clamping buckle 120 will not be worn, thereby ensuring the durable use of the overall structure.

[0048] Please refer to the attached Fig. 9The clamping buckle 120 includes a first clamping plate 121 and a second clamping plate 122 connected to the side wall of the optical module 100. The clamping buckle 120 also includes a torsion elastic member 123 for controlling the bending state of the first clamping plate 121 and the second clamping plate 122. The first clamping plate 121 and the second clamping plate 122 are movably connected. Under the action of the torsion elastic member 123, the first clamping plate 121 and the second clamping plate 122 are in a normally flat state. An inwardly concave receiving groove is opened at the bottom of the optical module 100 for accommodating the clamping buckle 120 as a whole, so as to ensure that the optical module 100 will not generate interference loss with the mechanical locking block 220 during the movement of the first locking sleeve 200.

[0049] The first clamping plate 121 and the second clamping plate 122 are bent into a V-shape, and the upper side wall of the mechanical locking block 220 is adapted to the V-shape after bending. The mechanical locking block 220 is completely fitted with the first clamping plate 121, which increases the contact area, reduces stress concentration, and avoids the loss of components.

[0050] It should be noted here that the first end of the clamping rod 320 is detachably connected to the inner wall of the second locking sleeve 300, and an inclined locking slope 321 is provided on the upper surface of the second end of the clamping rod 320. The locking slope 321 can cooperate with the bottom of the optical module 100 to support and limit the bottom of the optical module 100. In the process that the optical module 100 and the first locking sleeve 200 move synchronously toward the inside of the second locking sleeve 300, the front end of the clamping rod 320 can be pressed against the clamping buckle 120 to control the elastic deformation of the clamping buckle 120; at the same time, the locking slope 321 can exert an upward force on the optical module 100, support and limit the optical module 100, and further ensure the stability of the optical module 100 limited in the first locking sleeve 200.

[0051] Please refer to the attached Figure 4 , Attachment Figure 5 Specifically, the hydraulic control device 400 includes a hydraulic pumping body 410, a delivery pipe 430 connected to the hydraulic locking assembly 230, and a conduction control valve 420 installed between the hydraulic pumping body 410 and the delivery pipe 430. The conduction control valve 420 has a conduction control end, and the control workpiece 310 is connected to the conduction control end. The conduction state of the conduction control valve 420 can be controlled by the control workpiece 310. After the conduction control valve 420 is in conduction, the first locking sleeve 200 can squeeze the hydraulic pumping body 410 and gradually compress it, and deliver the control oil in the hydraulic pumping body 410 to the hydraulic locking assembly 230 through the delivery pipe 430, thereby realizing the control of the telescopic state of the hydraulic locking assembly 230.

[0052] It should be noted here that the end of the control workpiece 310 is fixedly connected to the conduction control end, and the position state of the valve core in the conduction control valve 420 can be controlled by rotating the control workpiece 310; a torsion elastic element is installed between the main part of the control workpiece 310 and the second locking sleeve 300, and the torsion elastic element can adjust the control workpiece 310 and the conduction control valve 420 to be in the first state normally, that is, the conduction control valve 420 is in a closed state; during the operation, the optical module 100 can be freely inserted into the first locking sleeve 200 to complete the preliminary photoelectric test; after the preliminary photoelectric test is qualified, the rotation control workpiece 310 is in the second state, at which time the conduction control valve 420 is turned on, and the staff pushes the optical module 100 and the first locking sleeve 200 from the outside to move synchronously toward the second locking sleeve 300, thereby squeezing the conduction control valve 420, and finally realizing the limit of the optical module 100 by the hydraulic locking assembly 230.

[0053] The hydraulic pumping body 410 here is elastic, and under the action of elasticity, it has a tendency to stretch; in the process of unlocking, the staff only needs to rotate the control workpiece 310 to be in the second state, and the hydraulic pumping body 410 automatically stretches under the action of elasticity, so as to realize the automatic pop-up of the first locking sleeve 200, and in this process, the hydraulic locking assembly 230 automatically contracts to realize the automatic unlocking of the optical module 100, and the staff can unhinderedly pull out the optical module 100 from the outside to realize the unlocking limit of the optical module 100, thereby improving the efficiency of unlocking and pulling out the optical module 100, reducing the material loss of unlocking and pulling out the optical module 100, and ensuring that the optical module 100 can be plugged and unplugged at a high frequency.

[0054] Specifically, the hydraulic pumping body 410 includes a pumping housing, a pumping piston 412 is sealed and slidably connected inside the pumping housing, a pumping control rod 411 is fixed to the first side of the pumping piston 412, the pumping control rod 411 penetrates the pumping housing and is located on the moving path of the first locking sleeve 200, a pumping chamber 414 is formed between the second side of the pumping piston 412 and the pumping housing, the pumping chamber 414 is connected to the conduction control valve 420, and an elastic element 413 is arranged in the pumping chamber 414, the elastic element 413 can push the pumping piston 412 to move toward the outside, so that the pumping control rod 411 has a tendency to extend toward the outside; at the same time, in the process of the first locking sleeve 200 moving toward the second locking sleeve 300, the oil in the pumping chamber 414 can be squeezed into the hydraulic locking assembly 230 to realize the extension control of the hydraulic locking assembly 230; the above structure has a simple control method and a compact structure, which meets the requirements of installation in the second locking sleeve 300.

[0055] The delivery pipeline 430 here includes a first delivery pipe body 431 and a second delivery pipe body 432 sealed and slidably connected to the first delivery pipe body 431. The retractable design between the first delivery pipe body 431 and the second delivery pipe body 432 can ensure the production and delivery of control oil between the hydraulic pumping body 410 and the hydraulic locking assembly 230, meeting the demand for movement of the first locking sleeve 200.

[0056] The present invention is further described below in conjunction with the locking and unlocking process of the optical module 100 .

[0057] Locking process: S1, control the hydraulic control device 400 to be in a non-conducting state; S2, insert the optical module 100 into the first accommodating chamber in the first locking sleeve 200; S3, complete a preliminary photoelectric conversion test on the optical module 100; S4, after the preliminary photoelectric conversion test of the optical module 100 is passed, control the hydraulic control device 400 to be in a conducting state; S5, push the first locking sleeve 200 and the optical module 100 from the outside to move synchronously toward the second locking sleeve 300 until the hydraulic control device 400 is in a fully compressed state; after the hydraulic control device 400 is in a fully compressed state, control the hydraulic control device 400 to be in a non-conducting state again, thereby completing the locking limit of the optical module 100.

[0058] Unlocking process: S1. Rotate the control workpiece 310 to control the hydraulic control device 400 to be in a conducting state. During this process, the hydraulic control device 400 extends and pushes the first locking sleeve 200 to move outward. At the same time, the control oil in the hydraulic locking assembly 230 flows back into the hydraulic control device 400 to release the restriction on the optical module 100; S2. Pull the optical module 100 out of the first accommodation chamber of the first locking sleeve 200. At this point, the unlocking process of the optical module 100 is completed.

[0059] In summary, the above-mentioned locking process can be carried out in stages. In the first stage, the optical module can be quickly plugged and unplugged for testing, which improves the efficiency of the plug-in and unplugging test while reducing losses; in the second stage, when locked, the locking effect is stable, ensuring the stable conversion of photoelectric signals; the above-mentioned unlocking process is simple and convenient, and the steps are simple. It is only necessary to adjust the control workpiece 310 to achieve the automatic pop-up of the optical module 100, and the unlocking process is carried out automatically. There is also no loss in the unlocking and unplugging process, which improves the maximum number of plug-in and unplugging times and the life of the optical module 100, and ensures the plug-in stability of the overall structure.
