Description

Technical Field

[0001] The invention relates to the technical field of QSFP optical modules, in particular to a device and a method for positioning a component of a QSFP optical module. Background Art

[0002] QSFP optical module is a four-channel small pluggable optical module, which has four independent full-duplex transceiver channels for high-density optical communication. It integrates the advantages of small size, hot pluggability, high density, etc., and is widely used in data centers, telecommunication networks, high-performance computing and other fields to meet the needs of high-speed data transmission.

[0003] When connecting optical module components, in order to ensure the accuracy and stability of the connection, it is usually necessary to set a plug-in locking structure at the component plug-in position to ensure that there will be no loosening and other problems after the plug-in is completed.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0044] See also Figure 1 to Figure 12 In an embodiment of the present invention, a device for positioning a QSFP optical module includes:

[0045] A first connection module 1 and a second connection module 6, wherein a plug connector 26 is fixed to the end of the first connection module 1, and a sleeve member 7 and a fixing plate 8 are fixed to the second connection module 6;

[0046] Also includes:

[0047] A positioning guide component, which is arranged on the first connection module 1 and cooperates with the sleeve fitting 7 to guide the sleeve fitting 7 to be sleeved onto the plug connector 26;

[0048] A plug-in guide assembly is arranged on the first connection module 1, and a follow-up rotating mechanism is arranged on the fixing plate 8, and the follow-up rotating mechanism includes a movable rod 14. When the movable rod 14 enters the plug-in guide assembly, the movable rod 14 rotates and performs a positive locking action on the movable rod 14;

[0049] The trigger locking mechanism is disposed on the fixing plate 8 and connected to the follow-up rotating mechanism. The trigger locking mechanism can be activated when the follow-up rotating mechanism moves to perform a reverse locking action on the movable rod 14 .

[0050] Specifically, when the first connection module 1 and the second connection module 6 are in a separated state, the movable rod 14 is locked in the follow-up rotating mechanism. When assembly is required, the second connection module 6 can be held by hand, and the sleeve 7 and the fixed plate 8 can be controlled to move toward the plug-in connector 26. Under the action of the positioning guide assembly, it can be ensured that the positions of the sleeve 7 and the plug-in connector 26 will not be offset. The fixed plate 8 will control the movable rod 14 to enter the plug-in guide assembly through the follow-up rotating mechanism. Under the action of the plug-in guide assembly, the movable rod 14 is rotated to a certain angle. When the sleeve 7 and the plug-in connector 26 are plugged in, After that, the deflection angle of the movable rod 14 reaches the maximum. At this time, the follow-up rotating mechanism no longer locks the movable rod 14, and controls the movable rod 14 to move a certain distance in the direction away from the first connecting module 1. Under the action of the plug-in guide assembly, the movable rod 14 is subjected to a positive locking action. At the same time, the follow-up rotating mechanism also drives the trigger locking mechanism to move. When the movable rod 14 is positively locked, under the action of the trigger locking mechanism, the movable rod 14 is subjected to a reverse locking action, thereby fixing the second connecting module 6 at the side end of the first connecting module 1, ensuring the plug-in stability of the sleeve 7 and the connector 26.

[0051] Preferably, by implementing a two-way locking measure on the movable rod 14, the plugging strength between the sleeve 7 and the plug connector 26 can be effectively ensured, making the connection more firm and reliable. Since the movable rod 14 is protected by the two-way locking, it can prevent the second connection module 6 from being impacted by external force or the locking mechanism from being triggered by the operator's misoperation, thereby preventing the plugging between the sleeve 7 and the plug connector 26 from becoming loose. This design greatly improves the stability and safety of the connection structure and avoids failures or accidents caused by loose connections during use.

[0052] See also Figure 1-Figure 3The positioning guide assembly includes a protective plate 2 and a side plate 3 fixed to the end of the first connection module 1 , the protective plate 2 is provided with a first guide groove 201 , and the side plate 3 is provided with a second guide groove 301 .

[0053] In detail, when it is necessary to connect the sleeve 7 and the connector 26, the second connecting module 6 can be held and the sleeve 7 can be controlled to move toward the connector 26. Since the cavity formed by the protective plate 2 and the side plate 3 is the same size as the sleeve 7, and the first guide groove 201 and the second guide groove 301 are formed at the ends of the protective plate 2 and the side plate 3, the size of the cavity end is larger than the size of the sleeve 7. When the sleeve 7 contacts the first guide groove 201 and the second guide groove 301, the sleeve 7 has not yet been released from the connector 26. Under the action of the first guide groove 201 and the second guide groove 301, the sleeve 7 is guided and positioned, so that the sleeve 7 can smoothly enter the internal cavity and be accurately inserted into the connector 26.

[0054] Preferably, the first guide groove 201 and the second guide groove 301 can be used to position the sleeve 7 to prevent the sleeve 7 and the connector 26 from being misaligned and applying force, which may cause damage to the sleeve 7 or the connector 26 or misconnection.

[0055] See also Figure 3-Figure 8 The plug-in guide assembly includes a plug-in sleeve 4 fixed on the first connection module 1 and symmetrically arranged, a guide groove is opened on the plug-in sleeve 4, a first spring 5 is fixed in the plug-in sleeve 4, and the guide groove includes a first straight groove 401, a first spiral groove 402, and a second straight groove 403 opened on the outer wall of the circumference of the plug-in sleeve 4, and the two ends of the first spiral groove 402 are respectively connected to the first straight groove 401 and the second straight groove 403.

[0056] It should be noted that when the first connection module 1 and the second connection module 6 are in a separated state, the first spring 5 is not stressed and is in a normal state, the first straight groove 401 passes through the opening of the plug sleeve 4 and is longer than the second straight groove 403 .

[0057] See also Figure 5 , Figure 7-Figure 12The follow-up rotating mechanism includes a fixed sleeve 9 fixed on the fixed plate 8, the fixed sleeve 9 is slidably connected to the movable rod 14, and a first limiting column 15 is fixed on the movable rod 14 to slide with the guide groove. An elastic component connected to the fixed sleeve 9 is provided on the fixed plate 8, and the elastic component includes an annular groove 10 and a first vertical groove 11 opened on the circumferential outer wall of the fixed sleeve 9, and the ends of the annular groove 10 and the first vertical groove 11 are connected to each other. A second limiting column 16 is fixed on the movable rod 14 to slide with the annular groove 10 and the first vertical groove 11. The elastic component also includes a guide column 12 fixed on the fixed plate 8, a support plate 13 is fixed at the end of the guide column 12, and a limiting ring 1401 is fixed at the end of the movable rod 14. A second spring 17 is sleeved on the movable rod 14, and the two ends of the second spring 17 are respectively abutted against the limiting ring 1401 and the support plate 13.

[0058] See also Figure 5 , Figure 7-Figure 12 The trigger locking mechanism includes a rotating sleeve 18 rotatably mounted on the fixed plate 8 and sleeved on the fixed sleeve 9, a fixing ring 19 is provided at the end of the rotating sleeve 18, and the fixing ring 19 is in contact with the second limiting column 16. A second vertical groove 20 that penetrates the fixing ring 19 and is slidably engaged with the second limiting column 16 is provided on the rotating sleeve 18, and a driven component connected to the guide column 12 is provided on the rotating sleeve 18, and the driven component includes a second spiral groove 21 provided on the outer wall of the circumference of the rotating sleeve 18, a movable sleeve 22 is slidably mounted on the rotating sleeve 18, and a limiting block 23 that is slidably engaged with the second spiral groove 21 is fixed on the inner wall of the movable sleeve 22, and a movable plate 24 that is slidably connected to the guide column 12 is fixed on the movable sleeve 22, and a third spring 25 is sleeved on the rotating sleeve 18, and the two ends of the third spring 25 are respectively in contact with the fixed plate 8 and the movable plate 24.

[0059] See also Fig.11 , Fig.12, further, when the first connection module 1 and the second connection module 6 are in a separated state, the second limiting column 16 is located at the end of the stroke of the annular groove 10 away from the first vertical groove 11, so that the movable rod 14 extends out of the fixed plate 8 to the maximum extent, and the second spring 17 is in a compressed state. Under the action of the second spring 17, the movable rod 14 is controlled by the limiting ring 1401 to have a tendency to move in a direction away from the fixed plate 8. The second limiting column 16 penetrates the annular groove 10 and then the second vertical groove 20, and is located at the end of the stroke of the second vertical groove 20 away from the fixed ring 19. At this time, the limiting block 23 is located in the second spiral groove 21 is toward the end of the stroke on the side of the second vertical slot 20, so as to control the movable plate 24 to be located at the end of the stroke on the side away from the fixed plate 8 through the movable sleeve 22, and the third spring 25 is in a compressed state. Under the action of the third spring 25, the movable sleeve 22 has a tendency to move toward the direction away from the fixed plate 8, so as to control the rotating sleeve 18 to have a tendency to rotate through the limit block 23 and the second spiral groove 21. The rotating sleeve 18 will control the movable rod 14 to have a tendency to move toward the direction away from the first vertical slot 11 through the second vertical slot 20 and the second limit column 16. At this time, the angle of the movable rod 14 is in a locked state.

[0060] See also Figure 5 , Figure 7 When the first connection module 1 and the second connection module 6 need to be connected, the second connection module 6 can be held by hand, and the sleeve 7 and the fixing plate 8 can be controlled to move toward the plug-in component 26. Under the action of the positioning guide component, the sleeve 7 can be accurately inserted into the plug-in component 26. At the same time, the fixing plate 8 will drive the fixing sleeve 9 to move, thereby controlling the synchronous movement of the movable rod 14 through the annular groove 10 and the second limiting column 16. Since the angle of the movable rod 14 is in a locked state, when the movable rod 14 enters the plug-in sleeve 4, the first limiting column 15 will enter the first straight groove 401 and move along the first straight groove 401 to compress the first spring 5. When the first limiting column When the movable rod 15 is separated from the first straight groove 401 and enters the first spiral groove 402, under the action of the first limiting column 15 and the first spiral groove 402, the movable rod 14 is rotated by a certain angle, and the movable rod 14 will drive the second limiting column 16 to slide along the annular groove 10, and drive the rotating sleeve 18 to rotate by a certain angle through the second vertical groove 20, and the rotating sleeve 18 will drive the second spiral groove 21 to move. Since the movable sleeve 22 and the movable plate 24 can only slide along the length direction of the guide column 12, under the action of the second spiral groove 21 and the limiting block 23, the movable plate 24 is controlled by the movable sleeve 22 to move toward the fixed plate 8, so as to compress the third spring 25;

[0061] Subsequently, when the sleeve fitting 7 and the plug-in fitting 26 are plugged in, the first limiting post 15 just moves to the connection position between the first spiral groove 402 and the second straight groove 403, the movable rod 14 rotates at the maximum angle, and the second limiting post 16 just moves to the connection position between the annular groove 10 and the first vertical groove 11, so that the second limiting post 16 is no longer locked. Under the action of the second limiting post 16, the second vertical groove 20 and the first vertical groove 11 overlap with each other and are located at the same axial position. Under the action of the second limiting post 16 and the second vertical groove 20, the rotating sleeve 18 is in a locked state.

[0062] At this time, the second spring 17 is elastically released, and pushes the movable rod 14 to move in the direction away from the fixed plate 8 through the limiting ring 1401, so as to control the second limiting column 16 to slide along the length direction of the first vertical slot 11 and the second vertical slot 20. At the same time, the first spring 5 is elastically released, and synchronously provides a force for the movable rod 14 to move in the direction away from the plug-in sleeve 4, so that the first limiting column 15 slides along the second straight slot 403. When the second limiting column 16 moves to the end of the stroke of the first vertical slot 11 away from the annular slot 10, the second limiting column 16 just disengages from the second vertical slot 20, and the angle of the rotating sleeve 18 is no longer locked. The third spring 25 is elastically released, and through the limiting ring 1401, the movable rod 14 is pushed to move in the direction away from the fixed plate 8, so as to control the second limiting column 16 to slide along the length direction of the first vertical slot 11 and the second vertical slot 20. The movable plate 24 controls the movement of the movable sleeve 22, thereby driving the rotating sleeve 18 to rotate toward the initial angle through the limit block 23 and the second spiral groove 21, so as to drive the fixed ring 19 to move, so that the second vertical groove 20 and the second limit column 16 are in a misaligned state. Under the action of the fixed ring 19, the second limit column 16 cannot move toward the fixed plate 8, so as to provide a reverse locking effect on the movable rod 14. During this process, when the first limit column 15 moves to the end of the stroke of the second straight groove 403 away from the first spiral groove 402, the movable rod 14 no longer moves. Under the action of the second straight groove 403 and the first limit column 15, a positive locking effect is provided to the movable rod 14.

[0063] Preferably, by controlling the movable rod 14 to be inserted into the plug-in sleeve 4, the movable rod 14 can be rotated to a certain angle by utilizing the guiding effect of the guide groove. After the plug-in connector 26 and the sleeve member 7 are plugged in, the movable rod 14 is unlocked. At this time, under the elastic force of the second spring 17 and the third spring 25, the movable rod 14 will move a certain distance. Subsequently, through the cooperation of the first limit column 15 and the second straight groove 403, a positive locking action is performed on the movable rod 14 to ensure that the position of the second limit column 16 remains unchanged. In this way, through the interference cooperation between the second limit column 16 and the fixing ring 19, the position of the follower rotating mechanism is also fixed, thereby ensuring that the connector 26 and the sleeve member 7 will not become loose after being plugged in.

[0064] Since the first limiting column 15 and the second limiting column 16 are both in a locked state, this design can provide a multiple locking effect for the first connection module 1 and the second connection module 6. Even if the second connection module 6 is impacted by an external force, or the movable rod 14 is acted upon by an external force, it will not affect the plugging stability of the plug connector 26 and the sleeve 7. This multiple locking mechanism significantly improves the reliability and safety of the connection structure.

[0065] If unlocking is required, the movable plate 24 can be manually pushed to move toward the fixed plate 8. Under the action of the limit block 23 and the second spiral groove 21, the second vertical groove 20 is controlled to move again to the matching position with the second limit column 16 by rotating the sleeve 18. At the same time, the movable rod 14 is manually pushed to move toward the plug-in sleeve 4, so that the first limit column 15 moves to the connection position of the first spiral groove 402 and the second straight groove 403, and the second limit column 16 will synchronously move to the connection position of the annular groove 10 and the first vertical groove 11, and the movable rod 14 is controlled to rotate a certain angle so that the first limit column 15 is screwed into the first spiral groove 402. At this time, under the elastic thrust of the first spring 5, the movable rod 14 can be controlled to disengage from the plug-in sleeve 4, thereby providing a force for the sleeve 7 to move in the direction away from the connector 26, so that the first connection module 1 is separated from the second connection module 6.

[0066] A device positioning method for a QSFP optical module comprises the following steps:

[0067] Step 1: Hold the second connection module 6 and control the sleeve 7 and the fixing plate 8 to move toward the plug-in component 26;

[0068] Step 2: Under the action of the positioning guide assembly, the sleeve member 7 is controlled to be positioned so that the sleeve member 7 is accurately sleeved on the plug-in connector 26;

[0069] Step 3: The fixed plate 8 will control the movable rod 14 to enter the plug-in guide assembly through the follow-up rotating mechanism, and under the action of the plug-in guide assembly, the movable rod 14 will be positively locked;

[0070] Step 4: The follow-up rotating mechanism will also drive the trigger locking mechanism to move, so as to perform a reverse locking action on the movable rod 14 .

[0071] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
