Description

Technical Field

[0001] This application relates to the field of optical communication technology, specifically to an optical module and an optical transceiver connection component. Background Technology

[0002] Pluggable optical modules generally need to have a shell-removal unlocking structure. When the optical module is inserted into the equipment cage, it can be locked in place to prevent it from coming loose and avoid interruption of the transmission signal. Moreover, when it needs to be removed, it can be easily pulled out of the equipment cage.

[0003] The connection between the optical module and the equipment cage is mainly achieved through a locking part and a spring-loaded structure; that is, the optical module is designed with a locking part of a fixed shape, and the equipment cage is designed with a spring-loaded structure of a corresponding opening shape. When it is necessary to remove the optical module from the equipment cage, the movable unlocking structure designed on the optical module can lift the spring-loaded structure in the equipment cage to release the optical module from the equipment cage.

[0004] Currently, optical module housings are typically made using die-casting molds, and the materials are limited to zinc alloy and die-cast aluminum alloy. After die-casting, the housing is electroplated with nickel to form a protective layer. During the process of inserting the optical module into the device cage and locking / unlocking, the spring clips will scratch the locking part to varying degrees. This scratching can cause the electroplating layer to peel off and scratches to the locking part of the optical module. If a zinc alloy housing is used, the electroplating layer will powder at the peeling points after long-term use, affecting the stability of the connection. Summary of the Invention

[0005] This application provides an optical module and an optical transceiver connection assembly, which can reduce wear at the locking position and improve the stability of the connection.

[0006] The embodiments of this application can be implemented as follows:

[0007] In one aspect of this application, an optical module is provided, including a housing and mounting portions disposed on opposite sides of the housing. A reinforcing member is provided on the mounting portion, and an unlocking member is slidably connected inside the housing. The housing can be inserted into a cage and is engaged with the locking tongue of the cage by the reinforcing member. The unlocking member can release the locking tongue from engaging the reinforcing member.

[0008] Optionally, the housing includes a bottom shell and a top cover that interlock, the mounting portion is located on opposite sides of the bottom shell, and the unlocking member is slidably connected to the bottom shell.

[0009] Optionally, the reinforcing member has a U-shaped structure, and the supporting arm of the reinforcing member is provided with positioning protrusions, and the bottom shell and the top cover are provided with positioning grooves, so that the positioning protrusions are engaged in the positioning grooves.

[0010] Optionally, the unlocking component includes a handle and a connecting arm connected to the handle, wherein the connecting arm is provided with an unlocking latch protrusion for abutting against the locking tongue.

[0011] Optionally, the unlocking card protrusion includes an extension and a bent portion connected to each other. The extension is connected to the connecting arm, and there is a preset angle between the extension and the connecting arm. The bent portion bends inward toward the unlocking member.

[0012] Optionally, the bottom shell includes a first baffle and a second baffle that are spaced apart, and a groove is formed between the first baffle and the second baffle to allow the connecting arm to slide along the groove.

[0013] Optionally, the connecting arm is provided with a hook, and a groove is formed on the first baffle, with the hook located within the groove.

[0014] Optionally, the reinforcement is made of stainless steel, tool steel or die steel.

[0016] Optionally, the cage includes an outer shell and locking tongues disposed on opposite sides of the outer shell, the locking tongues being bent inward toward the inner side of the outer shell to engage with the reinforcement of the optical module.

[0017] Compared with existing technologies, the beneficial effects of the embodiments of this application include, for example:

[0018] The optical module and optical transceiver connection assembly provided in the embodiments of this application, through a housing and mounting portions provided on opposite sides of the housing, wherein the mounting portions are pre-reserved mounting positions on the housing, facilitating the installation of reinforcing members at these positions. When the optical module is engaged with the cage, the reinforcing members ensure that areas prone to abrasion by the locking tongue are engaged with the locking tongue through the reinforcing members, preventing wear at the locking and limiting positions during the assembly and disassembly of the optical module and the cage.

[0035] Currently, optical module housings are typically manufactured using die-casting molds, followed by nickel plating after die-casting. During the insertion and unlocking process of the optical module into the device cage, the spring contacts can scrape the locking area to varying degrees. This scraping causes the electroplating layer to peel off and scratches to the locking area. If a zinc alloy housing is used, the plating layer may even powder at the peeling points after long-term use, affecting the stability of the connection. This application provides the following technical solution to overcome the above problems.

[0036] Please refer to Figure 1 and Figure 2 This embodiment provides an optical module 10, including a housing 11 and mounting portions disposed on opposite sides of the housing 11. A reinforcing member 12 is provided on the mounting portion. An unlocking member 13 is also slidably connected inside the housing 11. The housing 11 can be inserted into a cage 20 and is engaged with the locking tongue 22 of the cage 20 by the reinforcing member 12. The unlocking member 13 can release the locking tongue 22 from engaging the reinforcing member 12.

[0037] Specifically, by providing mounting portions on opposite sides of the housing 11, it is convenient to install the reinforcing member 12 at the mounting portions. When the optical module 10 is locked and fixed between the cage 20, the locking tongue 22 of the cage 20 can be locked at the reinforcing member 12 to ensure the stability of the relative positional relationship between the optical module 10 and the cage 20. When it is necessary to remove the optical module 10 from the cage 20, it is only necessary to use the unlocking member 13 to elastically deform the locking tongue 22 to avoid locking with the reinforcing member 12, and then the optical module 10 can be removed from the cage 20. In addition, by setting the locking position with the locking tongue 22 as the reinforcing member 12, it is possible to avoid being scratched and worn by the locking tongue 22, so as to ensure stability during use.

[0038] The optical module 10 provided in this embodiment of the application includes a housing 11 and mounting portions on opposite sides of the housing 11. The mounting portions are pre-reserved mounting positions on the housing 11, facilitating the installation of reinforcing members 12 at these positions. When the optical module 10 is engaged with the cage 20, the reinforcing members 12 engage with the locking tongue 22 at locations prone to abrasion, preventing wear at the locking points during assembly and disassembly of the optical module 10 and the cage 20. When the optical module 10 needs to be removed from the cage 20, the unlocking member 13 simply releases the locking tongue 22 from the reinforcing member 12. This method reduces wear at the locking positions and improves connection stability.

[0039] like Figure 3 As shown, the housing 11 includes a bottom shell 112 and a top cover 114 that are interlocked. The mounting parts are located on opposite sides of the bottom shell 112, and the unlocking part 13 is slidably connected to the bottom shell 112.

[0040] Specifically, by configuring the housing 11 into a form where the bottom shell 112 and the top cover 114 cooperate, it is convenient to install other components inside the housing 11, and it also facilitates the installation of the reinforcing member 12. In addition, by sliding the unlocking member 13 to the bottom shell 112, the relative position of the unlocking member 13 and the locking tongue 22 can be changed, thereby controlling the locking tongue 22 through the unlocking member 13 to achieve the locking or unlocking of the locking tongue 22 on the reinforcing member 12.

[0041] like Figure 3 and Figure 4 As shown, the reinforcing member 12 has a U-shaped structure, and the supporting arm 122 of the reinforcing member 12 is provided with positioning protrusions 124 respectively. The bottom shell 112 and the top cover 114 are respectively provided with positioning grooves so that the positioning protrusions 124 are engaged in the positioning grooves.

[0042] Specifically, by setting the reinforcing member 12 into a U-shaped structure, it is easier to allow space for the unlocking member 13, thus facilitating better cooperation between the unlocking member 13 and the locking tongue 22. Furthermore, by providing positioning protrusions 124 on the support arms 122 of the reinforcing member 12, when the reinforcing member 12 is installed in the mounting section, the positioning protrusions 124 can respectively engage with the positioning grooves of the bottom shell 112 and the top cover 114, thereby limiting the movement of the reinforcing member 12 relative to the shell 11 and ensuring the reliability of the connection.

[0043] like Figure 5 As shown, the unlocking component 13 includes a handle 132 and a connecting arm 134 connected to the handle 132. The connecting arm 134 is provided with an unlocking protrusion 136, which is used to abut against the locking tongue 22.

[0044] Specifically, the handle 132 facilitates the application of force to the unlocking member 13, allowing the unlocking member 13 to slide relative to the housing 11. When the unlocking member 13 slides into the housing 11, the unlocking latch 136 can be engaged within the U-shaped space of the reinforcing member 12, thus limiting the unlocking latch 136. When the latch 22 is engaged with the reinforcing member 12, the end of the latch 22 abuts against the end of the support arm 122. At this time, if the unlocking member 13 is slid outward from the housing 11, the unlocking latch 136 can apply force to the latch 22, causing the end of the latch 22 to deviate from the end of the support arm 122, thereby engaging the reinforcing member 12.

[0045] like Figure 6 As shown, the unlocking card protrusion 136 includes an extension 1362 and a bent portion 1364 connected to each other. The extension 1362 is connected to the connecting arm 134, and there is a preset angle between the extension 1362 and the connecting arm 134. The bent portion 1364 bends inward toward the unlocking member 13.

[0046] Specifically, by setting a preset angle between the extension 1362 and the connecting arm 134, the extension 1362 can form a guide slope. As the unlocking member 13 moves relative to the housing 11 in the unlocking direction, the unlocking latch 136 can cause the locking tongue 22 to gradually deviate away from the reinforcing member 12, thereby releasing the locking tongue 22 from the reinforcing member 12. Furthermore, by bending the bending portion 1364 inwards towards the unlocking member 13, a smooth transition between the extension 1362 and the locking tongue 22 is ensured, preventing jamming. It is understandable that the unlocking latch 136 and the connecting arm 134 can be integrally bent, which helps reduce production costs.

[0047] like Figure 5 and Figure 7As shown, the bottom shell 112 includes a first baffle 1122 and a second baffle 1124 spaced apart, and a sliding groove is formed between the first baffle 1122 and the second baffle 1124 so that the connecting arm 134 can slide along the sliding groove.

[0048] Specifically, a groove is formed between the first baffle 1122 and the second baffle 1124, which can limit the connecting arm 134 between the first baffle 1122 and the second baffle 1124, thus ensuring that the connecting arm 134 slides along a specific track. In addition, when the bottom shell 112 and the top cover 114 are fastened together, the top cover 114 can also limit the connecting arm 134 to ensure that the connecting arm 134 always slides within the groove.

[0049] like Figure 5 , Figure 7 and Figure 8 As shown, a hook 138 is provided on the connecting arm 134, and a groove 1126 is formed on the first baffle 1122, with the hook 138 located within the groove 1126.

[0050] Specifically, by positioning the hook 138 within the slot 1126, the sliding length of the connecting arm 134 relative to the slide groove is the length of the slot 1126, thus limiting the sliding distance of the unlocking component 13 and preventing it from slipping out of the housing 11. The hook 138 and the connecting arm 134 can be integrally bent, which helps reduce production costs. Furthermore, the unlocking component 13 of this application has a simple and effective structure, eliminating the need for complex transmission mechanisms and further reducing overall production costs.

[0051] In an optional embodiment of this application, the reinforcing member 12 is made of stainless steel, tool steel, or die steel. This ensures the strength of the reinforcing member 12 and prevents scratch damage while also reducing production costs.

[0052] like Figure 9 As shown in the illustration, this application also discloses an optical transceiver connection assembly, including a cage 20 and an optical module 10 from the aforementioned embodiments. The optical module 10 is pluggable and detachable from the cage 20. This optical transceiver connection assembly has the same structure and beneficial effects as the optical module 10 from the aforementioned embodiments. The structure and beneficial effects of the optical module 10 have been described in detail in the aforementioned embodiments and will not be repeated here.

[0053] Please continue to refer to this. Figure 9 The cage 20 includes an outer shell 21 and locking tongues 22 disposed on opposite sides of the outer shell 21. The locking tongues 22 are bent inward toward the outer shell 21 so as to be held by the reinforcing member 12 of the light module 10.

[0054] Specifically, the outer shell 21 and the locking tongue 22 can also be integrally bent. In the initial state, the locking tongue 22 bends inward toward the outer shell 21. When the housing 11 of the optical module 10 slides into the outer shell 21, the locking tongue 22 is deformed by force to ensure that the housing 11 slides in smoothly. When the housing 11 slides in to the depth corresponding to the position of the reinforcing member 12, the locking tongue 22 returns to its original shape and engages with the reinforcing member 12. When it is necessary to remove the optical module 10, the locking tongue 22 is deformed again by the unlocking member 13 to disengage from the engagement with the reinforcing member 12, thereby ensuring that the optical module 10 can be removed smoothly.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
