[0002] This application claims priority to Chinese patent application number 202022144953.9, filed on September 24, 2020, entitled “Optical Module and Optoelectronic Device,” which is hereby incorporated by reference. Technical Field

[0003] The present invention relates to the field of optical communication technology, and in particular to an optical module and an optoelectronic device using the optical module. Background Art

[0004] When in use, the optical module needs to be inserted into the cage of the host and locked and fixed with the host. When the optical module needs to be unplugged from the host, the optical module needs to be unlocked before it can be pulled out of the cage of the host, so an unlocking structure is provided on the optical module. In the related art, the optical module is provided with a lock buckle on the surface of the base, and a spring is provided inside the host cage, and the spring cooperates with the lock buckle to lock and fix the optical module. However, since this lock buckle cannot move, during the process of pulling out the optical module, the lock buckle squeezes the spring clip, causing the spring clip to deform before the optical module can be taken out. This structure can easily cause damage to the lock buckle of the optical module after multiple plugging and unplugging of the optical module, making it impossible to lock the optical module with the host, affecting the use of the optical module. Summary of the Invention

[0023] In one embodiment of the present invention, the pull rod, the two cantilevers, the two connecting rods and the two rotating rods are an integrated structure.

[0024] In one embodiment of the present invention, a limiting block is protruded from the surface of the rotating rod, and the limiting block abuts against the surface of the locking member.

[0029] The optical module of the present invention includes a housing, a locking member, and a pull ring. The pull ring is rotatably connected to the housing and the locking member. When the optical module is inserted into the host cage, the locking member's latch protrudes from the housing surface and is locked to the host. When the optical module needs to be removed from the host cage, the pull ring is rotated relative to the housing. Simultaneously, the pull ring drives the locking member relative to the housing, allowing the latch in the locking member to retract into the interior of the housing and disengage the latch from the retaining structure on the host cage. This prevents wear on the latch of the locking member when the optical module is removed from the host cage, and prevents the optical module from becoming locked to the host cage after repeated insertion and removal. Compared to the prior art, the optical module of the present invention is equipped with a latch that is movable relative to the housing, reducing wear on the latch during insertion and removal of the optical module, thereby improving the reliability of the optical module remaining locked to the host cage even after long-term use.

[0047] The present invention provides an optical module 100 .

[0048] Reference Figures 1 to 9 In an optical module 100 according to an embodiment of the present invention, the optical module 100 includes:

[0049] Housing 10;

[0050] A locking member 30 movably disposed on the housing 10 , the locking member 30 having a lock catch 31 , and the lock catch 31 protruding from a surface of the housing 10 ; and

[0051] The pull ring 50 is rotatably disposed on one side of the shell 10 and is also rotatably connected to the locking member 30. When the pull ring 50 is in an unlocked state, it can rotate relative to the shell 10 to retract the lock buckle 31 into the shell 10.

[0052] The optical module 100 of the present invention includes a housing 10, a locking member 30, and a pull ring 50. The pull ring 50 is rotatably connected to the housing 10 and the locking member 30. When the optical module 100 is inserted into the host cage, the latch 31 of the locking member 30 protrudes from the surface of the housing 10 and is locked to the host. When the optical module 100 needs to be removed from the host cage, the pull ring 50 is rotated relative to the housing 10. Simultaneously, the pull ring 50 drives the locking member 30 relative to the housing 10, allowing the latch 31 of the locking member 30 to retract into the interior of the housing 10 and disengage from the retaining structure of the host cage. This ensures that the latch 31 of the locking member 30 is not worn when the optical module 100 is removed from the host cage, and prevents the optical module 100 from becoming locked to the host cage after repeated insertion and removal. Compared with the prior art, the optical module 100 in the technical solution of the present invention is provided with a lock 31 that can move relative to the housing 10 to reduce the wear of the lock 31 when the optical module 100 is plugged in and out, thereby improving the reliability of the optical module 100 remaining locked with the host cage after long-term use.

[0053] It should be noted that the housing 10 has a cavity formed inside it, which houses electronic components such as the optical transmitter and receiver, as well as a circuit board. The housing 10 also has an optical port that connects to the cavity, through which the cable extends into the cavity and connects to the optical transmitter and receiver. Furthermore, a pull ring 50 is attached to the end of the housing 10 where the optical port is located, making it easier for operators to manually grasp the pull ring 50 and insert and remove the optical module 100.

[0054] Reference Figures 1 to 6 In one embodiment of the present invention, the housing 10 includes:

[0055] an upper shell 11, wherein the pull ring 50 is rotatably connected to one side of the upper shell 11; and

[0056] A lower shell 13, the lower shell 13 is detachably connected to the bottom of the upper shell 11, and the lower shell 13 is further provided with a clearance opening 131;

[0057] The locking member 30 is connected to one end of the pull ring 50. The locking member 30 is clamped between the upper shell 11 and the lower shell 13 and can rotate relative to the shell 10 so that the lock buckle 31 passes through the clearance opening 131 and protrudes from the surface of the lower shell 13 or retracts into the lower shell 13.

[0058] In the technical solution of one embodiment of the present invention, the upper shell 11 and the lower shell 13 are detachably connected by screws, and enclose a housing cavity for accommodating photoelectric elements. By adopting a structure in which the upper shell 11 and the lower shell 13 are detachably connected to the shell 10, the installation and fixation of the internal photoelectric elements can be facilitated. Among them, the pull ring 50 is rotatably connected to the upper shell 11, and the locking member 30 is clamped between the upper shell 11 and the lower shell 13 and rotatably connected to the upper shell 11. At the same time, a clearance opening 131 for the lock buckle 31 to pass through is also provided in the lower shell 13. In this way, under the drive of the pull ring 50, the locking member 30 can rotate relative to the shell 10, so that the lock buckle 31 can protrude from the surface of the lower shell 13 or retract into the interior of the lower shell 13.

[0059] Reference Figures 3 to 6 In one embodiment of the present invention, the pull ring 50 is provided with a first rotating shaft hole 111 and a second rotating shaft hole 571 , and the central axes of the first rotating shaft hole 111 and the second rotating shaft hole 571 are collinearly arranged;

[0060] A first rotating shaft 111 is protruded from the side wall of the upper shell 11 , and a second rotating shaft 33 is protruded from the side wall of the locking member 30 . The first rotating shaft 111 is rotatably inserted into the first rotating shaft 111 hole, and the second rotating shaft 33 is rotatably inserted into the second rotating shaft hole 571 .

[0061] The side wall surface of the locking member 30 is also protruding with a third rotating shaft 35, and the third rotating shaft 35 is spaced apart from the second rotating shaft 33. The upper shell 10 is also provided with a third rotating shaft hole 113, and the third rotating shaft 35 is inserted into the third rotating shaft hole 113. The locking member 30 is inserted into the third rotating shaft hole 113 with the center axis of the third rotating shaft 35.

[0062] In one embodiment of the present invention, the number of each of the first rotation axis hole 531, the second rotation axis hole 571, and the third rotation axis hole 113 is two, and the two first rotation axis holes 531, the two second rotation axis holes 571, and the two third rotation axis holes 113 are all arranged opposite each other. Correspondingly, the first rotation axis 111 is respectively protruded from opposite side walls of the upper shell 11, and the second rotation axis 33 and the third rotation axis 35 are both protruded from opposite side walls of the locking member 30, and the second rotation axis 33 and the third rotation axis 35 are spaced apart. Both sides of the pull ring 50 are connected to the first rotating shaft 111 and the second rotating shaft 33. When the pull ring 50 is pulled and rotated relative to the upper shell 11, it rotates relative to the housing 10 about the central axis of the first rotating shaft 111. At the same time, the pull ring 50 is also connected to the second rotating shaft 33, and through the second rotating shaft 33, it drives the locking member 30 to rotate about the central axis of the third rotating shaft 35. This causes the lock catch 31 to retract along the clearance opening 131 into the lower shell 13, separating the lock catch 31 from the retaining structure on the host cage, thereby unlocking the optical module 100. Furthermore, the first rotating shaft 111 and the upper shell 11 are integrally structured. The second rotating shaft 33 and the third rotating shaft 35 are also integrally structured with the locking member 30.

[0063] Reference Figure 6 In one embodiment of the present invention, the second rotating shaft hole 571 is a special-shaped hole.

[0064] In the technical solution of one embodiment of the present invention, the second rotation axis hole 571 is a special-shaped hole, for example, an arc-shaped hole or a U-shaped hole. The shape of the second rotation axis hole 571 is not limited herein. The second rotation axis 33 can rotate in the direction of the extension of the second rotation axis hole 571, providing a power source for the entire locking member 30 to rotate relative to the housing 10, so that the lock catch 31 of the locking member 30 can be retracted into the housing 10, thereby reducing the difficulty of unlocking the optical module 100.

[0065] Reference Figure 7 and Figure 8 In one embodiment of the present invention, the pull ring 50 includes:

[0066] Tie rod 51;

[0067] Two cantilevers 53, one end of each cantilever 53 is connected to the two ends of the pull rod 51 respectively, and the other end extends away from the pull rod 51, and the end of each cantilever 53 away from the pull rod 51 is provided with the first rotating shaft hole 531;

[0068] Two connecting rods 55 , one end of each connecting rod 55 being connected to an end of the cantilever 53 away from the pull rod 51 , and the end of each connecting rod 55 away from the cantilever 53 extending toward the inner side of the housing 10 ; and

[0069] Two rotating rods 57, one end of the rotating rod 57 is connected to the end of the connecting rod 55 away from the cantilever 53, and the end of the rotating rod 57 away from the connecting rod 55 extends away from the lower shell 13, and the rotating rod 57 is provided with a second rotating shaft hole 571.

[0070] In the technical solution of one embodiment of the present invention, the pull rod 51, two cantilever arms 53, two connecting rods 55, and two rotating rods 57 are integrated into a single structure to enhance the strength of the pull ring 50. The pull ring 50 can be made of plastic and can be integrally molded by injection molding. Each rod of the integrally molded pull ring 50 has a plate-like structure, enhancing its strength.

[0071] In one embodiment, the pull ring 50 may be made of metal, for example, steel bars or steel alloys, to further increase the strength of the pull ring 50 and prevent deformation of the pull ring 50. The metal pull ring 50 may be integrally formed using a sheet metal process. The end face of the pull ring 50 formed using the sheet metal process is circular, i.e., the pull ring 50 is in the shape of a round rod.

[0072] Reference Figure 8 In one embodiment of the present invention, a limiting block 573 is protruded from the surface of the rotating rod 57 , and the limiting block 573 abuts against the surface of the locking member 30 .

[0073] In the technical solution of one embodiment of the present invention, the limit block 573 is integrally formed with the rotating rod 57 and the connecting rod 55. The limit block 573 is positioned near one end of the connecting rod 55. Thus, when the optical module 100 is locked, the limit block 573 abuts against the surface of the locking member 30, restricting rotation of the locking member 30 relative to the housing, thereby improving the reliability of the locking member 30 when the optical module 100 is locked. To unlock, a force is applied to the pull ring 50, causing it to rotate relative to the housing, retracting the locking member 30 into the housing to achieve the unlocking operation.

[0074] Reference Figure 5 and Figure 6 In one embodiment of the present invention, at least a portion of the rotating rod 57, the connecting rod 55 and the cantilever 53 are connected to form a slot (not shown), and at least a portion of the upper shell 11 is held in the slot.

[0075] In the technical solution of one embodiment of the present invention, the pull ring 50 forms an open ring structure. At the two ends of the opening of the pull ring 50, a rotating rod 57, a connecting rod 55 and at least part of a cantilever 53 are connected to form a U-shaped card slot, which can be fixed to the upper shell 11 to improve the reliability of the fixation of the pull ring 50 and the shell 10.

[0076] Further, refer to Figures 4 to 8 In one embodiment of the present invention, the pull rod 51 is provided with a limiting convex bump 511 on the surface facing the upper shell 11, and the surface of the upper shell 11 is provided with a limiting groove, and the limiting convex bump 511 is inserted into the limiting groove.

[0077] In one embodiment of the present invention, a limiting protrusion 511 and a limiting groove are provided on the surfaces of the pull rod 51 and the upper shell 11, respectively. The limiting protrusion 511 is inserted into the limiting groove to limit the rotation of the pull ring 50 relative to the shell 10, thereby maintaining the optical module 100 locked with the mainframe cage. Furthermore, in one embodiment of the present invention, a buckle plate 513 is provided on the side of the pull rod 51, and the buckle plate 513 is arranged toward the lower shell 13. The provision of the buckle plate 513 facilitates the operator to manually grasp the pull ring 50, so that the force applied to the pull ring 50 disengages the limiting protrusion 511 from the limiting groove, thereby allowing the pull ring 50 to rotate toward the lower shell 13. When the pull ring 50 rotates to the bottom, the locking member 30 is unlocked, allowing the optical module 100 to be quickly removed from the mainframe cage. Furthermore, in some embodiments, the limiting convex bump 511 and the limiting groove are arc-shaped structures that adapt to each other. The arc surface can reduce the difficulty of unlocking the pull ring 50 and improve the user experience.

[0078] The present invention also proposes an optoelectronic device (not shown), which includes a host and an optical module 100. The specific structure of the optical module 100 refers to the above embodiment. Since this optoelectronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0079] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
