Optical transceiver

Abstract

A light transceiver device includes a housing, a shell removing member, a bottom cover and a pull handle. The housing includes a head and a first clamping member. The first clamping member is connected to the head. The head has a receiving space. The first clamping member is detachably clamped to a second clamping member of a flexible clamping sheet of a cage. The shell removing member is located in the receiving space and has an original position and an unclamping position. The bottom cover includes a cover body and a resilient member, wherein the cover body is fixedly arranged on the head, the resilient member is connected to the cover body and extends from the cover body towards the receiving space, and the resilient member normally applies a resilient force to the shell removing member to position or move the shell removing member to the original position. The pull handle is movably arranged on the head of the housing. When the pull handle is moved relative to the head of the housing by an external force, the pull handle pushes the shell removing member to the unclamping position, so that the shell removing member pushes the flexible clamping sheet of the cage, thereby separating the second clamping member of the flexible clamping sheet from the first clamping member of the housing.

Description

Technical Field

[0001] This invention relates to an optical transceiver, and more particularly to a pluggable optical transceiver. Background Technology

[0002] In modern high-speed communication networks, optical transceivers are typically used to achieve optical communication, and these transceivers are usually installed in electronic communication equipment. To increase the flexibility of system design and ease of maintenance, the optical transceivers are plugged into corresponding cages in the communication equipment in a pluggable manner. Generally, this cage is mounted on a circuit board. To define the electrical and mechanical interface between the optical transceiver module and its corresponding cage, various standards have been proposed, such as the XFP (10 Gigabit Small Form Factor Pluggable) standard for 10 Gigabit communication rates and the QSFP (Quad Small Form Factor Pluggable) standard.

[0003] Generally, optical transceivers, such as optical modules and optical transceivers, need to be equipped with a locking mechanism to ensure that the transceiver is securely locked in the cage when inserted into it, preventing it from coming loose and thus avoiding signal interruption. In addition, the optical transceiver also needs to be equipped with a shell-removal mechanism to work in conjunction with the locking mechanism, allowing it to easily release the lock and detach from the cage.

[0004] Existing optical transceivers have shell removal mechanisms that consist of multiple parts, such as rocker arms, springs, and levers. This requires multiple installation steps to assemble these parts into the housing, and finally, the bottom cover is used to secure them. Therefore, the shell removal mechanisms of existing optical transceivers have relatively complex structures and a large number of parts, making it impossible to reduce component production costs and resulting in inconvenience during installation and disassembly, leading to poor assembly efficiency. Summary of the Invention

[0005] The present invention provides an optical transceiver device that helps to solve the problems of high manufacturing cost and poor assembly efficiency of existing shell removal mechanisms.

[0006] An embodiment of the present invention discloses an optical transceiver for detachably inserting into a cage. The optical transceiver includes a housing, a shell ejector, a bottom cover, and a handle. The housing includes a head and a first latching member, wherein the first latching member is connected to the head, the head has a receiving space, and the first latching member is used to detachably latch a second latching member of a flexible locking tab of the cage. The shell ejector is located in the receiving space and has an initial position and an unlocked position. The bottom cover includes a cover body and an elastic member, the cover body is fixedly disposed on the head, the elastic member is connected to the cover body and extends from the cover body into the receiving space, and the elastic member normally applies an elastic force to the shell ejector to position or move the shell ejector to its initial position. The handle is movably disposed on the head of the housing. When the pull handle is subjected to an external force and moves relative to the head of the shell, the pull handle pushes the shell release component to the unfastening position, so that the shell release component pushes against the flexible locking piece of the cage, thereby separating the second locking piece of the flexible locking piece from the first locking piece of the shell.

[0007] Another embodiment of the present invention discloses an optical transceiver for detachably inserting into a cage. The optical transceiver includes a housing, a rocker arm, an elastic element, and a handle. The housing includes a head and a first latching member, wherein the first latching member is connected to the head and is used to detachably latch a second latching member of a flexible engagement piece of the cage. The rocker arm is rotatably disposed on the head of the housing and has an initial position and an unfastened position. The elastic element is disposed on the head of the housing and normally applies an elastic force to the rocker arm to position or move the rocker arm to the initial position. The handle is rotatably disposed on the head of the housing. When the handle is rotated relative to the head by an external force, the handle pushes the rocker arm to the unfastened position, causing the rocker arm to push against the flexible engagement piece of the cage, thereby separating the second latching member of the flexible engagement piece from the first latching member of the housing. The housing has a bottom surface and an assembly groove at its head. The assembly groove includes a release section, a first mounting section, and a second mounting section. The release section is recessed from the bottom surface. The first and second mounting sections are respectively connected to the release section, and the extension directions of the first and second mounting sections are different from the extension direction of the release section. A pivot portion of the rocker is rotatably disposed in the first mounting section, and a pivot portion of the handle is rotatably disposed in the second mounting section.

[0008] According to the optical transceiver device disclosed in the above embodiments, by integrating the elastic element with the bottom cover as one piece, or by directly setting the rocker and pull handle in the mounting section of the housing head, the number of parts for the housing removal mechanism of the optical transceiver device can be reduced, making it have a relatively simple structure, thereby reducing the production cost of parts and making the installation and disassembly of parts more convenient, thereby improving the assembly efficiency of the product.

The following embodiments further illustrate the viewpoints of the present invention, but are not intended to limit the scope of the present invention in any way.

[0078] Please see Figures 1 to 4 ,in Figure 1 This is a three-dimensional schematic diagram of the optical transceiver device according to the first embodiment of the present invention. Figure 2 for Figure 1 A three-dimensional schematic diagram of the other side of the optical transceiver. Figure 3 for Figure 2 Partial and exploded schematic diagrams of the optical transceiver device, and Figure 4 for Figure 2 A partial side view cross-sectional diagram of an optical transceiver.

[0079] The optical transceiver 1 of this embodiment is detachably inserted into a cage 9. The optical transceiver 1 is, for example, but not limited to, an optical module or optical transceiver, such as a Small Form-Factor Plugable (SFP) optical transceiver, a Small Form-Factor Plugable Double-Density (SFP-DD) optical transceiver, and a Dual Small Form-Factor Plugable (DSFP) optical transceiver. The optical transceiver 1 includes a housing 10, a shell ejector 20, a bottom cover 30, and a pull handle 40.

[0080] The housing 10 includes an insertion portion 11 and a head 12 connected together. In this embodiment, the housing 10 is used to house a photoelectric conversion circuit (not shown) and electronic and optical components required to realize the photoelectric conversion function.

[0081] The insertion part 11 is for pluggable insertion into the cage 9. The housing 10 also includes a first latching member 110, which is connected to the head 12. The first latching member 110 is for detachably latching a second latching member 91 of a flexible engagement piece 90 of the cage 9. In this embodiment, the first latching member 110 of the housing 10 is a latching protrusion, and the second latching member 91 of the flexible engagement piece 90 of the cage 9 is a latching groove, wherein the first latching member 110 (latching protrusion) has a guide slope 111 and a stop surface 112, and the flexible engagement piece 90 of the cage 9 has a guide part 92. During the insertion of the optical transceiver 1 into the cage 9, the guide ramp 111 of the first latching member 110 pushes against and guides the guide portion 92 of the flexible engaging piece 90, causing the flexible engaging piece 90 to deform and move away from the first latching member 110. When the first latching member 110 (latching protrusion) and the second latching member 91 (latching groove) correspond to each other, the guide portion 92 disengages from the guide ramp 111 and is no longer abutted by the first latching member 110, causing the flexible engaging piece 90 to reset towards the first latching member 110, thereby causing the first latching member 110 to latch onto the second latching member 91. Furthermore, when the first latching member 110 latches onto the second latching member 91, the stop surface 112 of the first latching member 110 abuts against the periphery of the second latching member 91 to limit the displacement of the optical transceiver 1 in a shell removal direction DR.

[0082] The head 12 of the housing 10 has a receiving space 120, a first rotating shaft groove 122, a second rotating shaft groove 123, and a hook groove 124. The receiving space 120 is used to receive the aforementioned shell-removing member 20. The housing 10 also includes two first fastening members 121, which are respectively formed on two side surfaces of the head 12 and located on opposite sides of the receiving space 120, and the aforementioned bottom cover 30 is assembled to the housing 10 through the first fastening members 121, the detailed component connection relationship of which will be described later. The first rotating shaft groove 122 and the second rotating shaft groove 123 are respectively used to receive the pivot structure of the aforementioned shell-removing member 20 and the pull handle 40, wherein the first rotating shaft groove 122 is located in the receiving space 120. The hook slot 124 is located on a top surface of the head 12 and is disposed opposite, for example, the receiving space 120. The hook slot 124 is used for the aforementioned pull handle 40 to hook and fix the pull handle 40 and restrict the rotation of the pull handle 40 relative to the housing 10. When it is necessary to pull out the optical transceiver 1, the operator can move the pull handle 40 out of the hook slot 124 before operation. The operation of the pull handle 40 will be described later.

[0083] In this embodiment, the shell ejector 20 is a rocker arm located in the accommodating space 120 of the head 12 of the shell 10, and the shell ejector 20 has an original position (e.g., Figure 4 (as shown) and an unfastening position (as shown) Figure 6(As shown). The shell ejector 20 includes a pivot portion 21, a first arm portion 22, and a second arm portion 23. The pivot portion 21 is rotatably located in a first pivot groove 122 of the head 12 of the shell 10, so that the pivot portion 21 is pivotally disposed on the shell 10. The first arm portion 22 and the second arm portion 23 are connected to opposite sides of the pivot portion 21.

[0084] The bottom cover 30 includes a cover body 31, two second fastening members 32, an elastic member 33, and two protruding ribs 34. The two second fastening members 32 are respectively disposed on opposite sides of the cover body 31 and respectively fasten to the two first fastening members 121 of the housing 10, thereby fixing the bottom cover 30 to the housing 10.

[0085] In this embodiment, the elastic element 33 is a spring sheet that is connected to the cover body 31 and extends from the cover body 31 toward the accommodating space 120. The elastic element 33 normally applies an elastic force along a first direction D1 to the first arm 22 of the shell-removing member 20 so that the shell-removing member 20 is positioned in the original position or moves from the unfastened position to the original position.

[0086] The ribs 34 protrude from the cover body 31 toward the accommodating space 120, thereby strengthening the overall structural strength of the bottom cover 30. In addition, the ribs 34 correspond to the two ends of the pivot portion 21 of the shell ejector 20, thereby confining the pivot portion 21 in the first rotation shaft groove 122 of the head 12 of the housing 10, preventing the pivot portion 21 of the shell ejector 20 from disengaging from the first rotation shaft groove 122, thereby ensuring that the shell ejection mechanism of the optical transceiver 1 can operate normally.

[0087] In this embodiment, the cover body 31, the second fastening member 32, the elastic member 33, and the protruding rib 34 of the bottom cover 30 are integrally formed, for example, by a stamping process. By integrating the elastic member 33 and / or the second fastening member 32 with the bottom cover 30, the number of parts in the mechanism for removing the outer casing of the optical transceiver 1 can be reduced, resulting in a relatively simple structure. This reduces the cost of parts production and makes the installation and disassembly of parts more convenient, thereby improving the assembly efficiency of the product.

[0088] A pull handle 40 is movably disposed on the housing 10. Specifically, in this embodiment, the pull handle 40 includes a pushing portion 41, a pivot portion 42, and a pull ring portion 43. The pivot portion 42 is rotatably located in the second rotational shaft groove 123 of the head 12 of the housing 10, thus the pivot portion 42 is pivotally disposed on the housing 10. The pivot portion 42 connects the pushing portion 41 and the pull ring portion 43, and the pushing portion 41 and the pull ring portion 43 extend toward opposite sides of the pivot portion 42 in a direction perpendicular to the axis of the pivot portion 42, wherein the pushing portion 41 is located in the receiving space 120, and the pull ring portion 43 extends beyond the housing 10. Figure 3 and Figure 4As shown, at least part of the bottom cover 30 covers the pivot portion 42 of the pull handle 40 to confine the pivot portion 42 within the second rotational shaft groove 123 of the head 12 of the housing 10. Specifically, the protruding rib 34 of the bottom cover 30 covers the pivot portion 42 of the pull handle 40 to confine the pivot portion 42 within the second rotational shaft groove 123 of the head 12 of the housing 10, thereby preventing the pivot portion 42 of the pull handle 40 from disengaging from the second rotational shaft groove 123, thus ensuring that the housing ejection mechanism of the optical transceiver 1 can operate normally.

[0089] The operator can plug and unplug the optical transceiver 1 by operating the pull handle 40. Please refer to [the relevant documentation / reference]. Figures 4 to 6 ,in Figure 5 for Figure 2 A side cross-sectional view of the pull ring of the optical transceiver handle disengaging from the hook groove on the head of the housing. Figure 6 for Figure 2 A side cross-sectional view of the optical transceiver in the unfastened position.

[0090] When the operator wants to remove the optical transceiver 1 from the cage 9, they first pull the pull ring 43 of the pull handle 40 to move the pull ring 43 out of the hook groove 124 of the head 12 of the housing 10 (e.g., Figure 5 As shown), this gives the pull handle 40 a degree of freedom to pivot relative to the housing 10. Next, a force is applied to the pull ring portion 43 along a pull handle rotation direction DP, causing the pull handle 40 to pivot relative to the housing 10 along the pull handle rotation direction DP, and causing the pushing portion 41 of the pull handle 40 to push the second arm portion 23 of the ejector 20 towards the first direction D1, thereby pivoting the ejector 20 to the unfastened position (as shown). Figure 6 As shown, while the ejector 20 pivots, the first arm 22 moves in a direction opposite to the first direction D1 and pushes against the flexible locking tab 90 of the cage 9, causing the second locking tab 91 of the flexible locking tab 90 to separate from the first locking tab 110 of the housing 10, thereby releasing the locking relationship between the optical transceiver 1 and the cage 9, giving the optical transceiver 1 the freedom to translate relative to the cage 9. Finally, the operator can remove the optical transceiver 1 from the cage 9 by holding the pull ring 43 along the ejection direction DR. For example, after the optical transceiver 1 is removed from the cage 9, when the operator releases the pull handle 40 (i.e., without applying force to the pull ring 43), the pushing part 41 of the pull handle 40 does not apply force to the first arm 22 of the ejector 20, causing the first arm 22 to move along the first direction D1 due to the elastic force applied by the elastic member 33, thereby moving the ejector 20 from the unlocked position back to its original position.

[0091] In this embodiment, the first latching member 110 of the housing 10 is a latching protrusion and the second latching member 91 of the flexible engaging piece 90 of the cage 9 is a latching groove, but the present invention is not limited thereto. In other embodiments, the first latching member of the housing may be, for example, a latching groove, and the second latching member of the flexible engaging piece of the cage may be a latching protrusion for engaging with the latching groove.

[0092] The hook groove 124 in this embodiment is optional, and the present invention is not limited thereto. That is to say, in other embodiments, the head of the housing may not have a hook groove for fixing the pull handle.

[0093] In this embodiment, the shell ejector 20 is exemplified by a rocker, but the invention is not limited thereto. In other embodiments, the shell ejector may be, for example, a slider, which is slidably located in the accommodating space of the head of the shell. The slider can be pushed from its original position to the unfastened position by a pull handle movable relative to the shell, thereby pushing against the flexible locking piece of the cage, causing the second locking member of the flexible locking piece to separate from the first locking member of the shell. Furthermore, when the pull handle is not under force, the slider can be positioned in its original position or moved from the unfastened position to its original position by the elastic member of the bottom cover. In embodiments where the shell ejector is, for example, a slider and does not have a pivot portion, the head of the shell may not have a first pivot groove.

[0094] In this embodiment, the first fastening member 121 of the housing 10 is a fastening protrusion, and the second fastening member 32 of the bottom cover 30 is a fastening groove, but the present invention is not limited thereto. In other embodiments, the first fastening member of the housing may be, for example, a fastening groove, and the second fastening member of the bottom cover may be a fastening protrusion for engaging with the fastening groove.

[0095] The present invention is not limited to the number of the first fastening member 121 and the second fastening member 32 described above. In some embodiments, the number of the first fastening member and the second fastening member may be, for example, one or more of each.

[0096] The present invention is not limited to the structure and form of the bottom cover 30 described above. In some embodiments, the bottom cover may be constructed such that the cover body and the elastic element are integrally formed, while the second fastening element and / or the protruding rib may be components independent of the cover body and are additionally provided to the cover body by means of engagement such as locking, welding, or snap-fit. Furthermore, the protruding rib 34 of the bottom cover 30 may be optional; in some embodiments, the bottom cover may not have a protruding rib.

[0097] In this embodiment, the handle 40 is pivotally mounted on the housing 10, but the invention is not limited thereto. In other embodiments, the handle is, for example, slidably mounted on the housing, with a portion of the handle located within the housing's accommodating space to push against the ejector, and another portion of the handle located outside the housing for the operator to grip and operate. In embodiments where the handle is slidably mounted on the housing without a pivot, the head of the housing may not have a second rotating shaft groove.

[0098] According to the optical transceiver device of the first embodiment described above, by integrating the elastic element and / or the second fastening element with the bottom cover, the number of parts for the mechanism of shell removal of the optical transceiver device can be reduced, making it have a relatively simple structure, thereby reducing the production cost of parts and making the installation and disassembly of parts more convenient, thereby improving the assembly efficiency of the product.

[0099] Please see Figures 7 to 10 ,in Figure 7 This is a three-dimensional schematic diagram of the optical transceiver device according to the second embodiment of the present invention. Figure 8 for Figure 7 A three-dimensional schematic diagram of the other side of the optical transceiver.

[0100] The optical transceiver 1b of this embodiment is detachably inserted into a cage 9b. The optical transceiver 1b is, for example, but not limited to, an optical module or optical transceiver, such as a Small Form-Factor Plugable (SFP) optical transceiver, a Small Form-Factor Plugable Double-Density (SFP-DD) optical transceiver, and a Dual Small Form-Factor Plugable (DSFP) optical transceiver. The optical transceiver 1b includes a housing 10b, a rocker arm 20b, a spring element 33b, and a pull handle 40b.

[0101] The housing 10b includes an insertion portion 11b and a head 12b connected together. In this embodiment, the housing 10b is used to house a photoelectric conversion circuit (not shown) and electronic and optical components required to realize the photoelectric conversion function.

[0102] The insertion part 11b is for pluggable insertion into the cage 9b. The housing 10b also includes a first latching member 110b, which is connected to the head 12b. The first latching member 110b is for detachably latching a second latching member 91b of a flexible engagement piece 90b in the cage 9b. In this embodiment, the first latching member 110b of the housing 10b is a latching protrusion, and the second latching member 91b of the flexible engagement piece 90b of the cage 9b is a latching groove. The first latching member 110b (latching protrusion) has a guide slope 111b and a stop surface 112b, and the flexible engagement piece 90b of the cage 9b has a guide part 92b. During the insertion of the optical transceiver 1b into the cage 9b, the guide ramp 111b of the first latching member 110b pushes against and guides the guide portion 92b of the flexible locking piece 90b, causing the flexible locking piece 90b to deform and move away from the first latching member 110b. When the first latching member 110b (latch protrusion) and the second latching member 91b (latch groove) correspond to each other, the guide portion 92b disengages from the guide ramp 111b and is no longer pushed against by the first latching member 110b, causing the flexible locking piece 90b to reset towards the first latching member 110b, thereby locking the first latching member 110b onto the second latching member 91b. Furthermore, when the first latching member 110b latches onto the second latching member 91b, the stop surface 112b of the first latching member 110b abuts against the periphery of the second latching member 91b to limit the displacement of the optical transceiver device 1b in a shell removal direction DR.

[0103] The head 12b of the housing 10b has a hook groove 124b and a top surface TS and a bottom surface BS facing each other. The hook groove 124b is located on the top surface TS and is used for hooking the aforementioned pull handle 40b to fix the pull handle 40b and restrict the rotation of the pull handle 40b relative to the housing 10b. When it is necessary to pull out the optical transceiver 1b, the operator can move the pull handle 40b out of the hook groove 124b before operation. The operation of the pull handle 40b will be described later.

[0104] The head 12b also has an assembly groove MG, which includes a release section MR, a first mounting section MM1, and a second mounting section MM2. The release section MR is recessed from the bottom surface BS, and the first mounting section MM1 and the second mounting section MM2 are respectively connected to the release section MR. The extension directions of the first mounting section MM1 and the second mounting section MM2 are both different from the extension direction of the release section MR. In this embodiment, the extension directions of the first mounting section MM1 and the second mounting section MM2 are both perpendicular to the extension direction of the release section MR, but the present invention is not limited thereto. In other embodiments, the extension directions of the first mounting section and the second mounting section may each form an acute angle with the extension direction of the release section.

[0105] The rocker arm 20b is rotatably disposed at the head 12b of the housing 10b, and the rocker arm 20b has an initial position (e.g., Figure 10 (as shown) and an unfastening position (as shown) Figure 12 (As shown). The rocker 20b includes a pivot portion 21b, a first arm portion 22b, and a second arm portion 23b. The pivot portion 21b is rotatably disposed in the first mounting section MM1 of the assembly groove MG of the head 12b, thereby the pivot portion 21b is rotatably disposed on the head 12b of the housing 10b. The first arm portion 22b and the second arm portion 23b are connected to opposite sides of the pivot portion 21b.

[0106] In this embodiment, the elastic element 33b is a spring, and the head 12b of the housing 10b also has a receiving groove CR. At least a portion of the elastic element 33b is located in the receiving groove CR, and the opposite ends of the elastic element 33b respectively abut against the bottom surface of the receiving groove CR and the second arm 23b of the rocker 20b. The elastic element 33b normally applies an elastic force along a second direction D2 to the second arm 23b of the rocker 20b to position the rocker 20b in its original position or move it from the unhooked position to its original position.

[0107] A pull handle 40b is movably disposed on the head 12b of the housing 10b. Specifically, in this embodiment, the pull handle 40b includes a push portion 41b, a pivot portion 42b, and a pull ring portion 43b. The pivot portion 42b is rotatably disposed in the second mounting section MM2 of the assembly groove MG of the head 12b, thus the pivot portion 42b is rotatably disposed on the head 12b of the housing 10b. The pivot portion 42b connects the push portion 41b and the pull ring portion 43b, and the push portion 41b and the pull ring portion 43b extend toward opposite sides of the pivot portion 42b in a direction perpendicular to the axis of the pivot portion 42b.

[0108] In this embodiment, the optical transceiver 1b limits the rocker arm 20b and the pull handle 40b by riveting the housing 10b. For details, please refer to... Figures 8 to 10After the pivot portion 21b of the rocker 20b and the pivot portion 42b of the handle 40b are respectively inserted into the first mounting section MM1 and the second mounting section MM2 through the release section MR of the assembly groove MG, the housing 10b is riveted with a punch at the riveting positions P1 and P2 on the bottom surface BS of the head 12b of the housing 10b, causing the housing 10b to deform slightly, thereby locking the pivot portion 21b of the rocker 20b and the pivot portion 42b of the handle 40b into the first mounting section MM1 and the second mounting section MM2 respectively, thus achieving a limiting position. In this embodiment, the first mounting section MM1 has a first stop surface SS1, and the first stop surface SS1 faces away from the bottom surface BS and is located on the side of the pivot portion 21b of the rocker 20b close to the bottom surface BS, so as to limit the pivot portion 21b of the rocker 20b in a direction parallel to the elastic force (e.g., the second direction D2). The second mounting section MM2 has a second stop surface SS2, which faces away from the bottom surface BS and is located on the side of the pivot portion 42b of the pull handle 40b close to the bottom surface BS, so as to limit the pivot portion 42b of the pull handle 40b in a direction parallel to the elastic force (e.g., the second direction D2).

[0109] Please refer to Figure 11 and Figure 12 ,in Figure 11 for Figure 8 A side cross-sectional view of the pull ring of the optical transceiver handle disengaging from the hook groove of the housing, and Figure 12 for Figure 8 This is a side cross-sectional view of the optical transceiver 1b in the unfastened position. In this embodiment, the first mounting section MM1 includes a first receiving portion MC1 and a first necking portion MS1 ​​connected to each other. The pivot portion 21b of the rocker 20b is rotatably located in the first receiving portion MC1, wherein the width W1 of the first receiving portion MC1 is greater than the diameter D1 of the pivot portion 21b, and the diameter D1 of the pivot portion 21b is greater than the width W2 of the first necking portion MS1, so as to confine the pivot portion 21b within the first receiving portion MC1 of the first mounting section MM1. By confining the pivot portion 21b within the first mounting section MM1 of the assembly slot MG, the pivot portion 21b of the rocker 20b can be prevented from detaching from the first mounting section MM1, thereby ensuring the normal operation of the unfastening mechanism of the optical transceiver 1b.

[0110] The second mounting section MM2 includes a second receiving portion MC2 and a second constricted neck MS2 connected to each other. The pivot portion 42b of the pull handle 40b is rotatably located in the second receiving portion MC2 of the second mounting section MM2. The width W3 of the second receiving portion MC2 is greater than the diameter D2 of the pivot portion 42b, and the diameter D2 of the pivot portion 42b is greater than the width W4 of the second constricted neck MS2, thereby confining the pivot portion 42b within the second receiving portion MC2 of the second mounting section MM2. By confining the pivot portion 42b within the second mounting section MM2 of the assembly slot MG, the pivot portion 42b of the pull handle 40b is prevented from detaching from the second mounting section MM2, thereby ensuring the proper operation of the ejection mechanism of the optical transceiver 1b.

[0111] The operator can plug and unplug the optical transceiver 1b by operating the pull handle 40b. Please refer to [further details]. Figures 10 to 12 When the operator wants to remove the optical transceiver 1b from the cage 9b, they first pull the pull ring 43b of the handle 40b to move the pull ring 43b out of the hook groove 124b of the head 12b (as shown). Figure 11 As shown), this allows the pull handle 40b to have a degree of freedom to pivot relative to the housing 10b. Next, a force is applied to the pull ring portion 43b along a pull handle rotation direction DP, causing the pull handle 40b to pivot relative to the housing 10b along the pull handle rotation direction DP, and causing the pushing portion 41b of the pull handle 40b to push the second arm portion 23b of the rocker 20b in a direction opposite to the second direction D2, thereby pivoting the rocker 20b to the unhooked position (as shown). Figure 12 As shown, while the rocker arm 20b pivots, the first arm 22b moves along the second direction D2 and pushes against the flexible locking tab 90b of the cage 9b, causing the second locking member 91b of the flexible locking tab 90b to separate from the first locking member 110b of the housing 10b. This releases the latching relationship between the optical transceiver 1b and the cage 9b, giving the optical transceiver 1b the freedom to translate relative to the cage 9b. Finally, the operator can remove the optical transceiver 1b from the cage 9b by holding the pull ring 43b along the shell removal direction DR. For example, after the optical transceiver 1b is removed from the cage 9b, when the operator releases the handle 40b (i.e., does not apply force to the pull ring 43b), the pushing part 41b of the handle 40b does not apply force to the second arm 23b of the rocker 20b, causing the second arm 23b to move along the second direction D2 due to the elastic force applied by the elastic member 33b, thereby moving the rocker 20b from the unhooked position back to the original position.

[0112] In this embodiment, the first latching member 110b of the housing 10b is a latching protrusion, and the second latching member 91b of the flexible engaging piece 90b of the cage 9b is a latching groove, but the present invention is not limited thereto. In other embodiments, the first latching member of the housing may be, for example, a latching groove, and the second latching member of the flexible engaging piece of the cage may be a latching protrusion for engaging with the latching groove.

[0113] In this embodiment, the elastic element 33b is a spring, but the invention is not limited thereto. In other embodiments, the elastic element may be, for example, a flexible sheet or a torsion spring.

[0114] The hook groove 124b in this embodiment is optional, and the present invention is not limited thereto. That is to say, in other embodiments, the head of the housing may not have a hook groove for fixing the pull handle.

[0115] According to the optical transceiver device of the second embodiment described above, by directly setting the rocker arm and pull handle in the mounting section of the housing head, the number of parts in the mechanism for removing the housing can be reduced, resulting in a relatively simple structure. This reduces the manufacturing cost of the parts and makes the installation and disassembly of the parts more convenient, thereby improving the assembly efficiency of the product. Furthermore, the rocker arm and pull handle of the optical transceiver device are fixed by riveting, providing a very reliable limit. This gives the mechanism for removing the housing excellent stability and resistance to damage, reducing the probability of malfunctions during use and thus minimizing quality risks.
