Description

Technical Field

[0001] The present invention relates to an optical transceiver device, in particular to a pluggable optical transceiver device and an ejection mechanism for this optical transceiver device. Background Art

[0002] In modern high-speed communication networks, optical transceiver devices are generally provided to achieve optical communication, and the optical transceiver devices are usually installed in electronic communication equipment. To increase the flexibility of system design and facilitate maintenance, the optical transceiver device is inserted into a corresponding cage provided in the communication equipment in a pluggable manner. Generally, this cage is provided on a circuit board. To define the electrical and mechanical interfaces between the optical transceiver module and the corresponding cage, various different standards have been proposed, such as the XFP (10Gigabit Small Form Factor Pluggable) standard and the QSFP (Quad SmallForm-factor Pluggable) standard for a communication rate of 10GB / s and other standards.

[0003] Generally, optical transceiver devices such as optical modules and optical transceivers are provided with a snap structure in a corresponding cage so that the optical transceiver device can be firmly locked in the cage when inserted to the final position. Therefore, the optical transceiver device needs to be configured with an ejection mechanism to cooperate with the snap structure of the cage so that the locked state can be easily released and the device can be detached from the cage.

[0004] Existing ejection mechanisms are provided with a pull handle so that an operator can pull out the optical transceiver device from the cage by pulling the pull handle. Since the specifications of the optical transceiver device are subject to the multi-source agreement (MSA), common types of pull handles are flexible plastic pull handles and rotatable metal pull handles. However, setting a plastic pull handle requires additional plastic molding processing, which is not conducive to simplifying the production process of the optical transceiver device and reducing the manufacturing cost. The metal pull handle has a small size to meet the specification requirements, making it difficult for the operator to hold the metal pull handle. In addition, both the plastic pull handle and the metal pull handle will block the optical fiber port of the optical transceiver device, increasing the difficulty of plugging and unplugging the optical fiber. Summary of the Invention

[0005] The present invention aims to provide an ejection mechanism for an optical transceiver device, which helps to solve the problems of high manufacturing cost and difficult operation existing in the existing ejection mechanisms.

[0006] The optical transceiver device disclosed by the present invention is adapted to be pluggably inserted into a cage, and the optical transceiver device includes a housing, a clamping member, and a pulling handle assembly. The housing has two opposite outer side surfaces. The clamping member is movably disposed on the housing, and the clamping member includes a connecting arm and two extending arms. The two extending arms are respectively connected to opposite sides of the connecting arm. The extending arms are respectively disposed on the two outer side surfaces of the housing, and the two extending arms are adapted to be detachably clamped to the cage. The pulling handle assembly includes a carrier, a pulling handle, and a locking structure. The carrier is fixed to the clamping member and together with the extending arms forms a receiving groove with an opening. The pulling handle is disposed on the carrier and can move along an ejection direction and has a closed position and an open position. The locking structure is located in the receiving groove. When the pulling handle is in the closed position, at least a part of the pulling handle is held in the receiving groove by the locking structure. When the pulling handle is in the open position, at least a part of the pulling handle protrudes from the opening of the receiving groove and is exposed outside, and the pulling handle drives the clamping member to move along the ejection direction.

[0007] The present invention further discloses an ejection mechanism of an optical transceiver device, including a clamping member and a pulling handle assembly. The pulling handle assembly includes a carrier, a pulling handle, and a locking structure. The carrier is fixed to the clamping member and together with the clamping member forms a receiving groove with an opening. The pulling handle is disposed on the carrier and can move along an ejection direction and has a closed position and an open position. The locking structure is located in the receiving groove. When the pulling handle is in the closed position, at least a part of the pulling handle is held in the receiving groove by the locking structure. When the pulling handle is in the open position, at least a part of the pulling handle protrudes from the opening of the receiving groove and is exposed outside, and the pulling handle drives the clamping member to move along the ejection direction.

[0008] According to the optical transceiver device and its ejection mechanism disclosed by the present invention, the pulling handle in the pulling handle assembly can move relative to the clamping member and has a closed position and an open position. The pulling handle in the closed position is received in the receiving groove formed between the clamping member and the carrier, so that the pulling handle does not block the optical fiber port and the optical fiber head inserted into the optical fiber port, thereby facilitating the operator to plug and unplug the optical fiber head. Most of the pulling handle in the open position protrudes from the opening of the receiving groove and is exposed outside, and the clamping member can be driven to move by pulling the pulling handle to remove the optical transceiver device from the cage. The ejection mechanism disclosed by the present invention avoids the pulling handle normally blocking the optical fiber port, making the operation of plugging and unplugging the optical fiber relatively simple.

[0058] The detailed features and advantages of the present invention are described in detail in the embodiments below. The content is sufficient for those of ordinary skill in the art to understand the technical content of the present invention and implement it accordingly. Based on the content disclosed in this specification, the protection scope, and the accompanying drawings, those of ordinary skill in the art can easily understand the related objectives and advantages of the present invention. The following embodiments further illustrate the viewpoints of the present invention in detail, but do not limit the scope of the present invention in any way.

[0059] Please refer to Figures 1 to 4 。 Figure 1 A three-dimensional schematic diagram of an optical transceiver device according to the first embodiment of the present invention. Figure 2 For Figure 1 An exploded schematic diagram of the optical transceiver device. Figure 3 For Figure 1 A partial top-down schematic diagram of the optical transceiver device. Figure 4 For Figure 1 A partial side cross-sectional schematic diagram of the optical transceiver device. In this embodiment, an optical transceiver device 1a is provided, which includes a housing 10, a fastening member 20, a pulling handle assembly 30a, and two elastic members 40. The optical transceiver device 1a is, for example but not limited to, an optical module or an optical transceiver, such as a Quad Small Form-factor Pluggable Double Density (QSFP-DD) optical transceiver.

[0060] The housing 10 is, for example but not limited to, a metal shell, which includes a connected head 110 and an insertion portion 120. The insertion portion 120 is used to be pluggably inserted into a cage (not shown separately). The head 110 of the housing 10 has two outer side surfaces 111 and two limiting grooves 112. The two limiting grooves 112 are formed on the two outer side surfaces 111 to accommodate the aforementioned two elastic members 40. In this embodiment, the housing 10 is used to accommodate an optoelectronic conversion circuit (not shown) and the electronic and optical components required to implement the optoelectronic conversion function, and the limiting grooves 112 do not penetrate the outer side surface 111 of the housing 10, so the housing 10 can protect the optoelectronic conversion circuit from dust or moisture. In addition, the head 110 of the housing 10 also has at least one optical fiber port 113 for a fiber optic plug (not shown) to be coupled to the optoelectronic conversion circuit inside the housing 10 along the optical fiber port 113.

[0061] The engaging member 20 includes a connecting arm 210 and two extending arms 220. The two extending arms 220 are respectively connected to opposite sides of the connecting arm 210, that is to say, the connecting arm 210 is located between the two extending arms 220. The extending arms 220 are movably arranged on the sliding rails on the outer side surface 111. Each of the two extending arms 220 includes an engaging portion 221 and a limiting portion 222, and the limiting portion 222 extends into the limiting groove 112 of the corresponding housing 10.

[0062] The pulling handle assembly 30a includes a bearing seat 310, a pulling handle 320 and a locking structure 330. The bearing seat 310 is fixed to the engaging member 20, and the bearing seat 310 and the extending arm 220 together form a receiving groove 100 with an opening 101. The pulling handle 320 is movably arranged on the bearing seat 310, and the locking structure 330 is located in the receiving groove 100. The locking structure 330 includes two buckle structures formed on the bearing seat 310, and each buckle structure includes two buckle elastic pieces 331 extending towards the pulling handle 320, and the pulling handle 320 has depressions 321 corresponding to the buckle elastic pieces 331. Figures 2 to 4 It is shown in that the buckle elastic pieces 331 of the locking structure 330 are integrally formed with the bearing seat 310. More specifically, the buckle elastic pieces 331 can be tongues formed on the bearing seat 310 by a stamping process, but the present invention is not limited thereto. The function of the pulling handle assembly 30a will be described later.

[0063] Two elastic members 40 are respectively arranged in the two limiting grooves 112 of the housing 10. The limiting portion 222 can push against the elastic member 40 located in the limiting groove 112. In this embodiment, the number of the limiting grooves 112 and the elastic members 40 is only an example and is not used to limit the present invention.

[0064] The engaging member 20 can move relative to the housing 10 to engage with or disengage from the cage. Further, the elastic member 40 can push against the limiting portion 222 of the engaging member 20, so that the extending arms 220 of the engaging member 20 can hook the buckle holes of the cage, and then the optical transceiver device 1a is firmly inserted into the cage. When it is necessary to pull out the optical transceiver device 1a, the engaging member 20 can be driven to move backward relative to the housing 10 by the pulling handle assembly 30a. At this time, the extending arms 220 of the engaging member 20 will disengage from the buckle holes of the cage and release the buckling effect between them, and then the optical transceiver device 1a can be removed from the cage.

[0065] An operator can achieve the pluggability of the optical transceiver device 1a through the pulling handle assembly 30a. Please refer to Figures 5 to 7 together, where Figure 5 is Figure 1 a three-dimensional schematic diagram of the pulling handle of the optical transceiver device in the open position, Figure 6 is Figure 5 a partial top view schematic diagram of the optical transceiver device, Figure 7 isFigure 5 Partial side cross-sectional schematic view of the optical transceiver device. The engaging member 20 and the pull handle assembly 30a together constitute the cartridge ejection mechanism of the optical transceiver device 1a. The pull handle 320 can move relative to the engaging member 20 and the carrier 310 along the cartridge ejection direction D and has a closed position and an open position.

[0066] As Figure 1 、 Figure 3 and Figure 4 shown, when the pull handle 320 is in the closed position, at least a part of the pull handle 320 is held in the receiving groove 100 by the locking structure 330. Specifically, the buckle elastic piece 331 closer to the opening 101 is buckled to the recess 321 of the pull handle, so that most of the pull handle 320 is fixed in the receiving groove 100, and only a small part protrudes through the opening 101 of the receiving groove 100 and is exposed outside. The operator can pull the pull handle 320 by holding the exposed part.

[0067] As Figures 5 to 7 shown, when the pull handle is in the open position, most of the pull handle 320 located in the receiving groove 100 protrudes from the opening 101 of the receiving groove 100 and is exposed outside. In addition, another buckle elastic piece 331 closer to the opening 101 is buckled to the recess 321 of the pull handle 320 to fix the position of the pull handle 320. The connecting arm 210 of the engaging member 20 has a pushed portion 211 located at the opening 101 of the receiving groove 100, and the pull handle 320 remains abutted against the pushed portion 211 of the connecting arm 210 of the engaging member 20. Since most of the pull handle 320 is exposed outside, at this time the operator can hold the pull handle 320 and continue to pull, so as to apply a pushing force to the pushed portion 211 through the pull handle 320 to drive the engaging member 20 to move along the cartridge ejection direction D.

[0068] Figure 8 Schematic diagram of the optical transceiver device according to the first embodiment of the present invention inserted into the cage.

[0069] Figure 9 For Figure 8 in the optical transceiver device out of the cage schematic diagram. In Figure 8 in, the optical transceiver device 1a is inserted into the cage 2, and the engaging portion 221 of the engaging member 20 is hooked to the buckle hole 21 of the cage 2, so that the optical transceiver device 1a is firmly inserted into the cage 2. The pull handle 320 is located in the receiving groove 100, and the pull handle 320 can be fixed in the closed position by the engagement between the buckle elastic piece 331 and the recess 321 (as Figure 3 and Figure 4 shown).

[0070] In Figure 9In [the above situation], when an operator wants to pull out the optical transceiver device 1a, the handle 320 can be pulled along the cartridge ejection direction D so that the handle 320 moves to the open position. The handle 320 can be fixed at the open position by the engagement between another snap spring 331 and the recess 321 (as shown in Figure 5 and Figure 6 ). At this time, the operator can insert a finger into the through hole 322 of the handle 320 to further pull the handle 320 backward, and the handle 320 is pulled and pushed against the pushed portion 211 of the engaging member 20, thereby driving the engaging member 20 to slide relative to the housing 10 along the cartridge ejection direction D. When the engaging member 20 slides along the cartridge ejection direction D, the engaging portion 221 disengages from the snap hole 21 of the cage 2, and then the operator can move at least a part of the optical transceiver device 1a outside the cage 2. When the operator releases the handle 320, the elastic member 40 releases the elastic potential energy to push against the limiting portion 222 of the extension arm 220 of the engaging member 20, so that the engaging member 20 is reset and can perform the operation of inserting the optical transceiver device 1a into the cage 2 again. The operator can further push against the handle 320 to make it return to the Figure 3 and Figure 4 closed position and be received in the receiving groove 100.

[0071] Referring to Figure 2 and Figure 4 , in this embodiment, the connecting arm 210 of the engaging member 20 corresponds to the top surface 114 of the head 110 of the housing 10, and the bearing seat 310 of the handle assembly 30a is located below the connecting arm 210, that is, the handle assembly 30a is between the connecting arm 210 and the top surface 114, but the present invention is not limited thereto. In other embodiments, the connecting arm of the engaging member and the handle assembly may be located below the housing and correspond to the bottom surface.

[0072] Referring to Figure 2 , Figure 4 and Figure 7 , in this embodiment, the bearing seat 310 of the handle assembly 30a has a guide rail 311, and the handle 320 also has a limiting groove 323 facing the bearing seat 310. The guide rail 311 is, for example but not limited to, a convex bulge or tongue piece formed on the bearing seat 310 by a stamping process, and it corresponds to the limiting groove 323. When the handle 320 moves from the Figure 4 closed position to the Figure 7 open position, the interference between the limiting groove 323 and the guide rail 311 can prevent the handle 320 from having left and right offsets orthogonal to the cartridge ejection direction D, thereby avoiding the operator from over-pulling the housing 10 and affecting the ongoing optical communication transmission operation.

[0073] Referring to Figure 5 and Figure 6, in this embodiment, when the handle 320 is in the open position, the area of the through hole 322 of the handle 320 exposed to the outside is greater than or equal to 144 square millimeters (mm 2 ), that is, the handle 320 in the open position provides at least 144 square millimeters of working area for the operator's finger to pass through the through hole 322. Since the thickness of an ordinary adult's finger is about 10-15 millimeters, the area of the through hole 322 exposed to the outside helps the operator to smoothly pull the handle 320.

[0074] The optical transceiver device disclosed in the first embodiment uses a snap spring and a handle in combination as an ejection mechanism, but the present invention is not limited thereto. Please refer to Figures 10 to 12 , in which Figure 10 is an exploded view of the optical transceiver device according to the second embodiment of the present invention. Figure 11 is Figure 10 a partial top view of the optical transceiver device. Figure 12 is Figure 11 a schematic diagram of the handle of the optical transceiver device in the open position. In this embodiment, the optical transceiver device 1b includes a housing 10, a engaging member 20, a handle assembly 30b, and two elastic members 40. The specific structures and functions of the housing 10, the engaging member 20, and the elastic member 40 can refer to the description of the corresponding elements in the first embodiment, which will not be repeated hereinafter.

[0075] The handle assembly 30b includes a carrier 310, a handle 320, and a locking structure 330. The carrier 310 is fixed to the engaging member 20, and the carrier 310 and the extension arm 220 together form a receiving groove 100 with an opening 101. The handle 320 is movably disposed on the carrier 310, and the locking structure 330 is located in the receiving groove 100. The locking structure 330 includes two elastic members 332, which are, for example, compression springs. The opposite ends of each elastic member 332 respectively contact the rear end of the handle 320 and the pushed portion 211 of the engaging member 20 located at the opening 101. In this embodiment, two elastic members 332 are provided as the locking structure 330, but the number of the elastic members 332 is not used to limit the present invention.

[0076] As Figure 11 shown, when the handle 320 is in the closed position, the elastic member 332 is between the rear end of the handle 320 and the pushed portion 211, and the elastic force of the elastic member 332 itself can keep the handle 320 in the closed position. At this time, the elastic member 332 does not apply a pushing force to the handle 320 or only applies a slight pushing force.

[0077] As Figure 12As shown, when the handle 320 moves from the closed position to the open position along the shell ejection direction D, the elastic member 332 is pushed by the handle 320 and compressed, thereby storing elastic potential energy. Since the handle 320 indirectly abuts against the pushed portion 211 of the engaging member 20 via the elastic member 332, when the operator pulls the handle 320, a pushing force is also applied to the engaging member 20 via the elastic member 332, thereby driving the engaging member 20 to move along the shell ejection direction D together, so that the buckling relationship between the engaging member 20 and the cage can be released. When the operator releases the handle 320, the handle 320 returns to the closed position by releasing the aforementioned elastic potential energy via the elastic member 332.

[0078] Please refer to Figures 13 to 15 , wherein Figure 13 is an exploded view of an optical transceiver device according to the third embodiment of the present invention, Figure 14 is Figure 13 a partial top view of the optical transceiver device of Figure 15 is Figure 14 a schematic diagram of the handle in the optical transceiver device of being in the open position. In this embodiment, the optical transceiver device 1c includes a housing 10, an engaging member 20, a handle assembly 30c, and two elastic members 40. The specific structures and functions of the housing 10, the engaging member 20, and the elastic member 40 can refer to the descriptions of the corresponding elements in the first embodiment, which will not be repeated hereinafter.

[0079] The handle assembly 30c includes a carrier 310, a handle 320, and a locking structure. The locking structure includes an elastic member 333, which is, for example but not limited to, a torsion spring. The carrier 310 has a pushed portion 312 located in the receiving groove 100. The metal ring of the elastic member 333 (torsion spring) is sleeved on the pushed portion 312, and the legs of the elastic member 333 extend to contact the rear end of the handle 320.

[0080] As Figure 14 shown, when the handle 320 is in the closed position, the elastic force of the elastic member 333 itself can keep the handle 320 in the closed position. At this time, the elastic member 332 does not apply a pushing force to the handle 320 or only applies a slight pushing force.

[0081] As Figure 15As shown, when the handle 320 moves from the closed position to the open position along the cartridge ejection direction D, the elastic member 333 is pushed by the handle 320 and compressed, thereby storing elastic potential energy. Since the handle 320 indirectly bears against the pushed portion 312 of the carrier seat 310 via the elastic member 333, when the operator pulls the handle 320, a pushing force is also applied to the carrier seat 310 via the elastic member 333, thereby driving the engaging member 20 fixed to the carrier seat 310 to move along the cartridge ejection direction D together. In this way, the buckling relationship between the engaging member 20 and the cage can be released. When the operator releases the handle 320, the handle 320 resets to the closed position by releasing the aforementioned elastic potential energy via the elastic member 333.

[0082] In summary, according to the optical transceiver device and its cartridge ejection mechanism disclosed in the present invention, the handle in the handle assembly can move relative to the engaging member and has a closed position and an open position. The handle in the closed position is received in the accommodation groove formed between the engaging member and the carrier seat, so that the handle does not block the optical fiber port and the optical fiber head inserted into the optical fiber port, which helps the operator to insert and remove the optical fiber head. Most of the handle in the open position protrudes from the opening of the accommodation groove and is exposed outside, and the optical transceiver device can be moved out of the cage by pulling the handle to drive the engaging member to move. The cartridge ejection mechanism disclosed in the present invention avoids the handle normally blocking the optical fiber port and makes the operation of inserting and removing the optical fiber relatively simple.

[0083] In addition, since the handle can be received in the accommodation groove and does not block the optical fiber port, the flexibility of the handle does not need to be considered. Both the handle and the engaging member can be made of metal material, which helps to reduce the manufacturing cost and manufacturing difficulty.
