Description

Technical Field

[0001] This invention relates to an optical transceiver device, and more particularly to an optical transceiver device comprising a handle and a slider. Background Technology

[0002] In modern high-speed communication networks, optical transceivers are typically used to enable optical communication, and these transceivers are usually installed within electronic communication equipment. To increase the flexibility of system design and ease of maintenance, the optical transceivers are plugged into corresponding cages within the communication equipment in a pluggable manner.

[0003] Generally, optical transceivers are inserted into a cage in a pluggable manner through the engagement of a handle and a slider. In existing optical transceivers, to prevent the handle and slider from falling off, screws are used to secure a clamping block to the transceiver housing to fix the handle, and the handle further stops the slider. Alternatively, existing optical transceivers may also use a spring to push the handle, further stopping the slider.

[0004] However, while screws and clamps can prevent the handle and slider from falling off, they increase the amount of material required to manufacture the optical transceiver and complicate the installation process. Using a spring to push the handle against the transceiver carries the risk of it easily falling off. In other words, existing optical transceivers cannot provide the function of preventing the slider and handle from falling off while simultaneously saving materials and simplifying the installation process. Summary of the Invention

[0005] The present invention provides an optical transceiver device that, while saving materials and simplifying the installation process, provides a function to prevent the slider and handle from falling off.

[0006] An embodiment of the present invention discloses an optical transceiver device for engaging a first latching structure on a latching portion of a cage. The optical transceiver device includes a housing, a second latching structure, a limiting protrusion, a slider, and a handle. The housing has an assembly side. The second latching structure is disposed on the assembly side of the housing and engages with the first latching structure. The limiting protrusion protrudes from the assembly side of the housing. The slider includes a slider body and a spring arm. The spring arm includes a cantilever and a hook. The cantilever includes a fixed end and a movable end opposite to each other. The fixed end is fixed to the slider body. The hook protrudes from the movable end toward the housing. The slider body is slidably disposed on the assembly side of the housing. The handle is pivotally disposed on the assembly side of the housing. At least a portion of the slider body is located on the side of the handle near the second latching structure. The hook is located on the side of the handle near the limiting protrusion. The handle is used to drive the slider body to push against the latching portion of the cage, thereby disengaging the second latching structure from the first latching structure on the latching portion.

[0007] According to the optical transceiver device disclosed in the above embodiments, since the fixed end of the cantilever of the spring arm is fixed to the slider body, and the hook protruding from the movable end of the cantilever is located on the side of the pull handle near the limiting protrusion, the engagement of the hook and the limiting protrusion prevents the slider or pull handle from falling off the housing. Furthermore, the limiting protrusion and the hook are located on the existing housing and slider respectively, eliminating the need for additional fasteners such as screws for fixation. In this way, the function of preventing the slider and pull handle from falling off is provided while saving materials and simplifying the installation process. Attached Figure Description

[0049] In this embodiment, the optical transceiver 10 is used to engage with a first latching structure 21 of a latching portion 22 of a cage 20. The latching portion 22 is, for example, a spring arm, and the first latching structure 21 is, for example, a latching hole. The optical transceiver 10 conforms to, for example, Small Form-factor Pluggable (SFP), Small Form-factor Pluggable Double Density (SFP-DD), or Dual Small Form-factor Pluggable (DSFP) specifications.

[0050] In this embodiment, the optical transceiver 10 includes a housing 100, a second snap-fit ​​structure 200, a limiting protrusion 300, two pivot seats 350, a slider 400, and a pull handle 500. The housing 100 has an assembly side 101. The second snap-fit ​​structure 200 is disposed on the assembly side 101 of the housing 100. The second snap-fit ​​structure 200 is, for example, a snap protrusion protruding from the assembly side 101 of the housing 100 and used to engage with the first snap-fit ​​structure 21. That is, the first snap-fit ​​structure 21 and the second snap-fit ​​structure 200 are, for example, matching snap holes and snap protrusions. It should be noted that in other embodiments, the first snap-fit ​​structure and the second snap-fit ​​structure may also be matching snap protrusions and snap holes, respectively.

[0051] The limiting protrusion 300 protrudes from the assembly side 101 of the housing 100. In this embodiment, the limiting protrusion 300 is integrally formed with the housing 100, for example. In this embodiment, the limiting protrusion 300 has a guiding slope 301, which is located on the side of the limiting protrusion 300 away from the housing 100. In other embodiments, the limiting protrusion 300 may not need to have a guiding slope 301.

[0052] The two pivot seats 350 protrude from the assembly side 101 of the housing 100. In this embodiment, the two pivot seats 350 are integrally formed with the housing 100, for example. It should be noted that in other embodiments, the limiting protrusion, the pivot seat, and the housing may also be multiple structures assembled together.

[0053] In this embodiment, the slider 400 includes a slider body 410, a spring arm 420, and a reset protrusion 430. In this embodiment, the slider body 410, the spring arm 420, and the reset protrusion 430 are, for example, integrally formed. It should be noted that in other embodiments, the slider body, the spring arm, and the reset protrusion may also be multiple structures assembled together.

[0054] The slider body 410 is slidably disposed on the assembly side 101 of the housing 100. In this embodiment, the slider body 410 has a pushing slope 411 and a relief groove 412. The pushing slope 411 is located on the side of the slider body 410 near the second snap-fit ​​structure 200. The relief groove 412 is recessed from the side of the slider body 410 near the second snap-fit ​​structure 200. Specifically, the relief groove 412 is recessed from the pushing slope 411. In this embodiment, the spring arm 420 includes a cantilever 421, a hook 422, and a structural reinforcing rib 423. The cantilever 421 includes a fixed end 4210 and a movable end 4211 opposite to each other, and is located in the relief groove 412. The fixed end 4210 is fixed to the slider body 410. In this embodiment, the fixed end 4210 has a pushing slope 4212. The inclined surface 4212 is located on the side of the fixed end 4210 away from the movable end 4211. The latch 422 protrudes from the movable end 4211 toward the housing 100. The structural reinforcing rib 423 protrudes from the side of the fixed end 4210 away from the housing 100 and is directly connected to the slider body 410 to increase the overall structural strength of the slider 400. The reset protrusion 430 protrudes from the bottom surface 4120 of the relief groove 412.

[0055] It should be noted that, in other embodiments, the slider body may not have the clearance groove 412, and the cantilever of the spring arm may protrude from the outer surface of the slider body. In other embodiments, the fixed end may not have the pushing slope 4212. In other embodiments, the slider body may not have the pushing slope 411. In other embodiments, the spring arm may not have the structural reinforcing rib 423.

[0056] The two pivot seats 350 are located on the side of the slider body 410 away from the second snap-fit ​​structure 200. Each pivot seat 350 has a pivot groove 351. The two pivot grooves 351 are recessed from the side of the two pivot seats 350 closest to the slider body 410.

[0057] The handle 500 is pivotally mounted on the assembly side 101 of the housing 100. Specifically, in this embodiment, the handle 500 includes an operating lever 510, two connecting rods 515, two pivot rods 520, and a push rod 530. The opposite ends of each pivot rod 520 are respectively connected to the operating lever 510 and the push rod 530. The opposite ends of the operating lever 510 are respectively connected to the two pivot rods 520 via the two connecting rods 515. The two pivot rods 520 are respectively pivotally mounted in the two pivot grooves 351 of the two pivot seats 350. At least a portion of the slider body 410 is located on the side of the handle 500 near the second snap-fit ​​structure 200. The hook 422 is located on the side of the handle 500 near the limiting protrusion 300. In this embodiment, the push rod 530 protrudes in a direction away from the operating lever 510, but this is not a limitation. In other embodiments, the push rod 530 may also be a straight rod. In other embodiments, the optical transceiver may not need to include two pivots 350.

[0058] The following describes the assembly process of the optical transceiver 10 according to the present invention. Please refer to... Figures 3 to 5 . Figure 4 and Figure 5 Presentation Figure 1 The assembly process of optical transceivers in [the context of the project]. For example... Figure 4 As shown, the slider body 410 is first slidably mounted on the assembly side 101 of the housing 100 along the sliding direction D, and the pivot rods 520 of the pull handle 500 are respectively pivotally mounted in the pivot grooves 351 of the pivot seat 350. It should be noted that the pivot rods 520 are pivotally mounted in the pivot grooves 351 of the pivot seat 350 in a manner that is, for example but not limited to, riveting the pivot rods 520 into the pivot grooves 351 of the pivot seat 350, causing a slight deformation of the pivot seat 350, thereby making the pivot rods 520 more firmly positioned in the pivot grooves 351 and preventing them from falling off. When the pivot rods 520 are respectively pivotally mounted in the pivot grooves 351 of the pivot seat 350, as... Figure 4 As shown, the hook 422 is located between the limiting protrusion 300 and the second latching structure 200, and the pull handle 500 is positioned along the sliding direction D. Next, as... Figure 5 As shown, the slider body 410 slides along the sliding direction D, causing the hook 422 to abut against the assembly side 101 of the housing 100 after moving along the guide ramp 301 of the limiting protrusion 300. In this way, the side of the hook 422 and the slider body 410 away from the hook 422 abuts against the limiting protrusion 300 and the push rod 530 of the pull handle 500, respectively. That is, the slider 400 is clamped between the limiting protrusion 300 and the push rod 530 of the pull handle 500, preventing the slider 400 from falling off the housing 100 during the assembly process. Next, as... Figure 3As shown, the operating lever 510 of the lever 500 is pivoted along the first pivot direction P1, causing the reset protrusion 430 to be pushed by the push rod 530, which in turn drives the slider body 410 away from the second latching structure 200. Then, the first latching structure 21 and the second latching structure 200 on the latching part 22 of the cage 20 are fastened together, thus completing the assembly of the optical transceiver 10 and the fastening of the optical transceiver 10 with the cage 20.

[0059] The following describes the shell removal operation of the optical transceiver 10. Please refer to [link / reference]. Figure 6 , Figure 6 Presentation Figure 1 The optical transceiver in the middle retracts its casing. For example... Figure 6 As shown, along the opposite Figure 3 The first pivot direction P1 and the second pivot direction P2 pivot the operating lever 510 of the pull handle 500, causing the push rod 530 to push against the fixed end 4210 of the cantilever 421 of the spring arm 420 of the slider 400, and thus driving the push slope 411 of the slider body 410 to push against the latching part 22 of the cage 20, so that the second latching structure 200 on the latching part 22 separates from the first latching structure 21, thereby completing the removal of the optical transceiver device 10.

[0060] The following describes the reset operation of the optical transceiver 10. Please refer to [link / reference]. Figure 7 , Figure 7 Presentation Figure 1 The optical transceiver in the middle is reset. For example... Figure 7 As shown, the operating lever 510 of the lever 500 is pivoted along the first pivot direction P1, causing the reset protrusion 430 to be pushed by the push rod 530, which in turn drives the slider body 410 away from the second latch structure 200, thus completing the reset action.

[0061] In other embodiments, the slider may also be free from the reset protrusion 430 and the slider body may be manually moved away from the second snap-fit ​​structure.

[0062] According to the optical transceiver device disclosed in the above embodiments, since the fixed end of the cantilever of the spring arm is fixed to the slider body, and the hook protruding from the movable end of the cantilever is located on the side of the pull handle near the limiting protrusion, the engagement of the hook and the limiting protrusion prevents the slider or pull handle from falling off the housing. Furthermore, the limiting protrusion and the hook are located on the existing housing and slider respectively, eliminating the need for additional fasteners such as screws for fixation. In this way, the function of preventing the slider and pull handle from falling off is provided while saving materials and simplifying the installation process.

[0063] Furthermore, since the pivot seat on which the handle is pivotally mounted not only prevents the handle from falling off but is also located on the existing housing, it further prevents the handle from falling off while saving materials and simplifying the installation process.
