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] The current unlocking method for optical modules is relatively complex, involving a plastic-coated pull ring molded onto the unlocking sheet metal. This often interferes with external components such as fiber optic patch cords, tail sleeves, and dust plugs, making fiber insertion and connection inconvenient. Research has revealed that the assembly tolerances and angles between the pull ring and the various components of the housing are crucial to the unlocking function, requiring strict control of the relevant dimensions. This imposes strict control on supplier process requirements and results in relatively high manufacturing costs. Furthermore, the existing pull ring unlocking sheet metal is exposed on the outside of the module, preventing the design of a retaining structure. This makes the pull ring sheet metal unlocking component susceptible to deformation or scratching during transportation, impacting product quality and leading to customer complaints. Summary of the Invention

[0003] The main purpose of the present invention is to provide an optical module unlocking device, aiming to solve the existing technical problems.

[0004] To achieve the above-mentioned purpose, the present invention provides an optical module unlocking device, comprising a base, an upper cover and a cage.

[0005] The base has a through hole, and a pressing member movable along a first direction is provided in the through hole;

[0006] The upper cover is provided with an unlocking member movable along the second direction, the unlocking member is provided with a convex plate, and the convex plate is connected to the tongue piece on the cage;

[0007] The end of the pressing member abuts against the unlocking member. When the pressing member moves along the first direction, it pushes the unlocking member to move along the second direction, so that the convex plate pushes the tongue on the cage to achieve unlocking.

[0008] Furthermore, the unlocking member includes two parallel side plates, the convex plate is provided at one end of the side plate, the other end of the side plate is connected through an end plate, a sliding portion is provided on the end plate, the sliding portion has an inclined surface, and the first end of the pressing member is inclined to fit the inclined surface.

[0009] Furthermore, a stop portion is provided at the end of the slide portion, and the stop portion is connected to a first elastic member provided on the upper cover.

[0010] Furthermore, the first elastic member is connected to the first surface or the second surface of the shifting portion, wherein the first elastic member is in a compressed state when initially connected to the second surface of the shifting portion and is connected to the shifting portion via a slider.

[0011] Furthermore, when the first elastic member is connected to the second surface of the shifting portion, the slider is limited by a limiting member, the limiting member is U-shaped, and one end of the limiting member is movably abutted against the slider, and the other end is abutted against the side plate, wherein an external protrusion is provided on the side plate, and when the pressing member moves along the first direction, the external protrusion squeezes the limiting member to release the first elastic member.

[0012] Furthermore, it also includes a push rod, which passes through the base and is connected to the unlocking member.

[0013] Furthermore, a protrusion is provided on the side plate, and the protrusion is connected to a second elastic member provided on the upper cover.

[0014] Furthermore, a third elastic member is provided in the through hole and is sleeved on the pressing member.

[0015] Furthermore, the upper cover and the base are staggered to form a gap, and the side panels move in the gap.

[0016] Furthermore, in the initial state, the pressing member has a first section located inside the through hole and a second section located outside the through hole. When the second section of the pressing member is fully extended into the through hole for unlocking, the first end of the pressing member does not separate from the inclined surface.

[0017] The beneficial effects of the present invention are embodied in:

[0018] The present invention innovates the existing pull ring unlocking method with a semi-automatic press-to-unlock method. The technical solution is to abandon the existing sheet metal + injection molding process pull ring and strap unlocking method, and adopt an all-metal sheet metal unlocking part linkage mechanism design to achieve a one-button automatic unlocking function, which is efficient and convenient, and avoids the problem that the rubber-coated pull ring often interferes with external parts such as fiber optic jumpers, tail sleeves, dust plugs, etc., which makes it inconvenient to plug and unplug and connect optical fibers.

[0032] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-3 、 Figure 10 and Figure 11 The present invention provides an optical module unlocking device, comprising a base 100, an upper cover 200 and a cage 300.

[0034] The base 100 has a through hole 101, and a through hole 101 is provided with a Figure 1A pressing member 400 that moves in the F1 direction;

[0035] The upper cover 200 is provided with a Figure 1 The unlocking member 500 (made of sheet metal) is movable in the F2 direction. The unlocking member 500 is provided with a convex plate 5001, which mates with the tongue 301 on the cage 300;

[0036] The end of the pressing member 400 abuts against the unlocking member 500. When the pressing member 400 moves along the first direction, it pushes the unlocking member 500 to move along the second direction, so that the protruding plate 5001 pushes the tongue 301 on the cage 300 to achieve unlocking.

[0037] The present invention uses all-metal sheet metal materials and sheet metal + plastic materials without a pull-ring unlocking method. This reduces the uncontrollability caused by the use of multiple processes, and the single sheet metal structure is more stable and reliable; the unlocking mechanism and the unlocking part are integrated and applied to the inside of the module, and the overall design is hidden, with better integrity; at the same time, the elimination of the external pull ring shortens the length of the exposed part of the module on the switch device, leaving more design space for the terminal application environment and equipment development; the pull ring and the unlocking part are integrated into one part, avoiding the size matching problem of the pull ring and the unlocking part, shortening the size chain, and avoiding the size chain matching error problem of subsequent products; the press-to-unlock method of the present invention also has the advantages of a small number of parts, simple process and easy assembly, efficient and convenient unlocking method, one-button unlocking, and stable reliability.

[0038] In one embodiment, see Figure 4 and Figure 5 The unlocking member 500 includes two parallel side plates 5002, the protruding plate 5001 is arranged at one end of the side plate 5002, and the other end of the side plate 5002 is connected through the end plate 5003. A sliding portion 5004 is provided on the end plate 5003, and the sliding portion 5004 has an inclined surface. The first end of the pressing member 400 is inclined to fit the inclined surface.

[0039] In this embodiment, when the optical module is unlocked, the pressing member 400 is operated in the first direction F1, and its end presses the slide portion 5004, driving the unlocking member 500 to move in the second direction F2. The protruding plate 5001 moves backward and outward to lift the optical squirrel cage connector tongue 301, thereby achieving unlocking.

[0040] In one embodiment, see Figure 4 and Figure 5 A stopper 5005 is provided at the end of the slide portion 5004 , and the stopper 5005 is connected to the first elastic member 501 provided on the upper cover 200 .

[0041] This embodiment is configured such that when the operating pressing member 400 drives the unlocking member 500 to move, the shifting portion 5005 compresses the first elastic member 501 to store force. When locking is required, the pressing member 400 is released, and the first elastic member 501 releases the stored force, which can quickly push the unlocking member 500 to reset and achieve locking.

[0042] In one embodiment, see Figure 6 and Figure 7 The first elastic member 501 is connected to the first surface 5005a or the second surface 5005b of the shifting portion 5005, wherein the initial state when the first elastic member 501 is connected to the second surface 5005b of the shifting portion 5005 is in a compressed state and is connected to the shifting portion 5005 through the slider 5011.

[0043] In this embodiment, when the first elastic member 501 is connected to the first surface 5005a of the stop portion 5005, when the optical module is locked, the pressing member 400 is released, and the first elastic member 501 releases the stored force, which can quickly push the unlocking member 500 back to achieve locking.

[0044] When the first elastic member 501 is connected to the second surface 5005b of the shifting portion 5005, during the unlocking process of the optical module, when the pressing member 400 moves along the first direction F1, the first elastic member 501 is released to provide power in the second direction F2 to the unlocking member 500, thereby reducing the difficulty of manual operation and improving the unlocking efficiency.

[0045] In one embodiment, see Figure 7 and Figure 8 When the first elastic member 501 is connected to the second surface 5005b of the shifting portion 5005, the slider 5011 is limited by the limiting member 503. The limiting member 503 is U-shaped, and one end of the limiting member 503 is movably in contact with the slider 5011, and the other end is in contact with the side plate 5002. Specifically, both ends of the limiting member 503 are arc-shaped structures, and springs are connected to both ends.

[0046] The side plate 5002 is provided with an outer protrusion 50021 . When the pressing member 400 moves along the first direction F1 , the outer protrusion 50021 presses the limiting member 503 to release the first elastic member 501 .

[0047] This embodiment is configured such that when the optical module is unlocked, the pressing member 400 is operated along the first direction F1 to push the unlocking member 500 to move along the second direction F2, and the limiting member 503 is pushed to move by the outer protrusion 50021, so that the limiting member 503 releases the limit on the slider 5011, releases the first elastic member 501, and applies a force in the second direction F2 to the unlocking member 500, thereby reducing the difficulty of manual operation and improving the unlocking efficiency.

[0048] It should be noted that, in this embodiment, the slide portion 5004 is located near the end of the end plate 5003 .

[0049] In one embodiment, see Figure 2 , further comprising a push rod 504 , which passes through the base 100 and is connected to the unlocking member 500 .

[0050] This embodiment is configured in such a way that, through the configuration of the push rod 504, it can assist in pushing the limiting member 503 when the first elastic member 501 is connected to the first surface 5005a of the shifting portion 5005, and re-compress the first elastic member 501 to facilitate unlocking the optical module again, and it can also operate the unlocking member 500 to move through the push rod 504 to achieve emergency unlocking when the relevant unlocking transmission mechanism fails.

[0051] In one embodiment, see Figure 4 and Figure 6 A protrusion 5006 is provided on the side plate 5002 , and the protrusion 5006 is connected to the second elastic member 502 provided on the upper cover 200 .

[0052] This embodiment is configured such that when the pressing member 400 is operated to drive the unlocking member 500 to move, the protrusion 5006 compresses the second elastic member 502 to store force. When locking is required, the pressing member 400 is released, and the second elastic member 502 releases the stored force, which can further assist the unlocking member 500 to quickly reset and achieve locking.

[0053] In one embodiment, see Figure 3 A third elastic member 401 is disposed within the through hole 101 and sleeved over the pressing member 400. This configuration of the present embodiment allows for the third elastic member 401 to be released when locking is desired, and the third elastic member 401 can drive the pressing member 400 to quickly reset. Simultaneously, the first elastic member 501 and the second elastic member 502 can be used to drive the unlocking member 500 to reposition the cage 300, thereby achieving locking. This allows for a simple operation of operating the pressing member 400 to unlock and releasing the pressing member 400 to lock.

[0054] In one embodiment, see Figure 9 The upper cover 200 and the base 100 are staggered and matched to form a gap K, and the side panel 5002 moves in the gap K.

[0055] This configuration of the present embodiment is equivalent to solidifying the movement trajectory of the unlocking member 500. At the same time, the sheet metal of the unlocking member 500 is designed inside the module tube shell, which can well protect the sheet metal unlocking member from being squeezed and deformed, thereby enabling the optical module to be unlocked and pulled out quickly, stably and reliably. The overall appearance is hidden and has the characteristics of novelty and beauty.

[0056] In one embodiment, see Figure 2 In the initial state, the pressing member 400 has a first section located inside the through hole 101 and a second section located outside the through hole 101. When the second section of the pressing member 400 is fully extended into the through hole 101 for unlocking, the first end of the pressing member 400 does not separate from the inclined surface.

[0057] With this arrangement of the present embodiment, there is no need to deliberately control the distance to which the pressing member 400 is pressed into the base 100. To unlock, the pressing member 400 only needs to be pressed into the base 100 until the protruding plate 5001 pushes up the tongue 301 on the cage 300. During the unlocking process, the first end of the pressing member 400 is always kept in contact with the inclined surface. When the pressing member 400 is released, the unlocking member 500 can be reset to its original path. This makes the operation simple and convenient, and is less prone to malfunctions.

[0058] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0059] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
