Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular 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] Typically, the equipment cage and its spring clips are made of hard stainless steel sheet metal, with hard and sharp end faces for the spring clips. The optical module housing is usually made using die casting, with materials limited to zinc alloy and die-cast aluminum alloy. After die casting, the housing is electroplated with nickel to form a protective layer. Under normal operating conditions, the protruding part of the unlocking mechanism presses against the spring clip, causing it to pop out of the locking part and unlock. However, during the process of the optical module being inserted into the equipment cage for locking and unlocking, the spring clip will scrape against the locking part to varying degrees. This scraping can cause the electroplating layer to peel off and scratches to form dents on the locking part of the optical module. Furthermore, because the spring clip is made of thin sheet metal, it is easily deformed. Sometimes, the edge of the spring clip will get caught in these dents, and after being pressed by the protruding part of the unlocking mechanism, it will twist and deform, preventing the spring clip from fully ejecting and causing unlocking failure. At the same time, the protruding part of the unlocking mechanism is generally formed by a single bending process, which is also prone to deformation and failure during unlocking, affecting the reliability of the unlocking process. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide an optical module and an optical transceiver connection component that can improve the reliability during unlocking.

[0006] This utility model discloses an optical module, including: a housing, and mounting portions disposed on opposite sides of the housing. The mounting portions are provided with reinforcing members, and an unlocking member is slidably connected inside the housing. The housing can be inserted into a cage and is held in place by the reinforcing members and the tongue of the cage. The unlocking member is provided with a retaining block, which can abut against the tongue to release the tongue from its holding and limiting position on the reinforcing member.

[0007] 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.

[0008] Optionally, the unlocking component includes a handle and a connecting arm connected to the handle, the end of the connecting arm being provided with a limiting part, the limiting part being engaged with the abutment block.

[0009] Optionally, the bottom shell is further provided with sliding grooves on opposite sides for limiting the position of the abutment block, and a portion of the reinforcing member extends to the sliding groove for sliding engagement with the abutment block.

[0010] Optionally, the abutment block includes a base connected to the limiting part, and a plurality of ribs formed on one side of the base. The ribs are provided with guide slopes for engaging with the end of the tongue. A guide groove is formed between adjacent ribs. The reinforcing member is provided with guide protrusions corresponding to the ribs. The guide grooves are slidable along the guide protrusions.

[0011] Optionally, the limiting part is T-shaped or L-shaped, and the base is provided with an insertion groove and a snap-fit ​​groove located on at least one side of the insertion groove, so that the limiting part snaps into the snap-fit ​​groove.

[0012] Optionally, the connecting arm is provided with a hook, and a groove is formed on the side wall of the bottom shell. The hook extends into the groove, and an elastic element is provided in the groove. The two ends of the elastic element abut against the hook and the side wall of the groove, respectively, so that the connecting arm is subjected to an elastic force that slides into the shell.

[0013] Optionally, a limiting protrusion is formed on one side of the connecting arm in the width direction, and a limiting groove corresponding to the limiting protrusion is formed on the top cover, and the limiting protrusion is slidably engaged in the limiting groove.

[0014] Optionally, the reinforcing member and the supporting block are made of stainless steel, tool steel or mold steel.

[0015] This utility model also discloses an optical transceiver connection assembly, including a cage and an optical module as described in any one of the above claims, wherein the optical module can be plugged into and connected to the cage; the cage includes a housing and tongues disposed on opposite sides of the housing, wherein the tongues are bent inward toward the housing to facilitate engagement with the reinforcing member of the optical module.

[0016] Compared with the prior art, the beneficial effects of the optical module and optical transceiver connection assembly provided by this utility model embodiment are as follows: By setting reinforcing members on the mounting parts on opposite sides of the housing, the strength of the connection between the optical module and the cage is significantly improved. Unlike the prior art where the locking part of the optical module housing is prone to electroplating peeling and scratches due to the spring clip, the reinforcing member can better withstand the interaction force between the reinforcing member and the tongue during insertion and unlocking, avoiding the formation of dents on the tongue due to scratches on the reinforcing member. This avoids unlocking failure caused by problems such as easy deformation of the thin sheet metal of the spring clip and dents on the edge hook, thus improving the reliability and stability of the optical module unlocking operation. In addition, the abutting cooperation method between the abutting block and the tongue, compared with the method of the protruding position of the unlocking structure squeezing the spring clip in the prior art, can avoid the deformation failure of the block itself affecting the abutting of the tongue. The cooperation between the reinforcing member and the abutting block makes the insertion and removal of the optical module smoother and helps to improve the reliability during unlocking.

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] This utility model embodiment provides an optical module 100, including: a housing 110, and mounting portions 112 disposed on opposite sides of the housing 110. The mounting portions 112 are provided with reinforcing members 120. The housing 110 is also slidably connected with an unlocking member 130. The housing 110 can be inserted into a cage 210 and is held in place by the reinforcing members 120 and the tongue 212 of the cage 210. The unlocking member 130 is provided with a retaining block 132, which can abut against the tongue 212 to release the retaining limit of the tongue 212 on the reinforcing member 120.

[0034] Specifically, the housing 110 is typically elongated, and the unlocking member 130 can slide within the housing 110 along its length to unlock the optical module 100. The housing 110 of the optical module 100 can be inserted into the cage 210. After insertion, the reinforcing member 120 engages with the tongue 212 of the cage 210. This engagement method secures the optical module 100 within the cage 210, preventing loosening and ensuring that the optical module 100 will not experience signal interruption during operation due to loosening. The unlocking member 130 is equipped with a retaining block 132. The main function of the retaining block 132 is to abut against the tongue 212 of the cage 210 when the optical module 100 needs to be removed, changing the engagement state between the tongue 212 and the reinforcing member 120, thereby releasing the retaining limit of the tongue 212 on the reinforcing member 120, allowing the optical module 100 to be easily pulled out of the cage 210.

[0035] The optical module 100 provided in this application embodiment significantly improves the strength of the connection between the optical module 100 and the cage 210 by providing reinforcing members 120 on the mounting portions 112 on opposite sides of the housing 110. Unlike the prior art where the locking portion of the optical module 100 housing 110 is prone to electroplating peeling and scratches due to scraping by the spring clip, the reinforcing member 120 can better withstand the interaction force between itself and the tongue 212 during insertion and unlocking, preventing the tongue 212 from forming dents on the reinforcing member 120 due to scraping. This avoids unlocking failures caused by problems such as easy deformation of the thin sheet metal of the spring clip and dents in the edge hook, thus improving the reliability and stability of the unlocking operation of the optical module 100. In addition, the abutment engagement method between the abutment block 132 and the tongue 212, compared with the method of squeezing the spring at the protruding position of the unlocking structure in the prior art, can avoid the deformation failure of itself affecting the abutment of the tongue 212. Through the cooperation of the reinforcing member 120 and the abutment block 132, the insertion and removal of the optical module 100 is smoother and it is conducive to improving the reliability during unlocking.

[0036] like Figure 1 and Figure 4 As shown, the housing 110 includes a bottom shell 114 and a top cover 116 that are interlocked. The mounting part 112 is located on opposite sides of the bottom shell 114, and the unlocking part 130 is slidably connected to the bottom shell 114.

[0037] Specifically, the interlocking design of the bottom shell 114 and top cover 116 makes the installation and removal of internal components of the optical module 100 more convenient. During production, electronic and optical components can be installed on the bottom shell 114 first, and then the top cover 116 can be closed for fixation, improving production efficiency. During maintenance and repair, the top cover 116 can be easily opened for inspection and replacement of internal components, reducing maintenance costs and difficulty. Furthermore, the sliding connection between the unlocking component 130 and the bottom shell 114 reduces the shaking and offset of the unlocking component 130 during sliding, ensuring that the abutment block 132 accurately abuts against the tongue 212, thereby improving the accuracy and reliability of the unlocking operation.

[0038] like Figure 2 and Figure 4 As shown, the unlocking component 130 includes a handle 134 and a connecting arm 136 connected to the handle 134. The end of the connecting arm 136 is provided with a limiting part 1362, which is engaged with the abutment block 132.

[0039] Specifically, the handle 134 is the part where the user operates the unlocking component 130, allowing the user to slide the unlocking component 130 relative to the housing 110 by pulling the handle 134. The connecting arm 136 connects the handle 134 to the abutment block 132, serving to transmit the pulling force. The end of the connecting arm 136 is provided with a limiting part 1362, which is used to engage with the abutment block 132. This engaging method facilitates the transmission of the pulling force of the handle 134 to the abutment block 132, enabling the abutment block 132 to abut against the tongue 212.

[0040] like Figure 4 As shown, the bottom shell 114 is also provided with sliding grooves 1142 on opposite sides for limiting the support block 132, and part of the reinforcing member 120 extends to the sliding grooves 1142 for sliding engagement with the support block 132.

[0041] Specifically, the reinforcing member 120 extends into the sliding groove 1142 and slides into the abutment block 132, allowing the reinforcing member 120 to better guide the movement of the abutment block 132 during the unlocking process. Simultaneously, the abutment block 132 can more effectively release the jamming state between the reinforcing member 120 and the tongue 212. This tight fit improves the overall performance of the optical module 100 unlocking structure and reduces potential malfunctions during unlocking. Furthermore, sliding grooves 1142 are provided on opposite sides of the bottom shell 114. The sliding grooves 1142 limit the movement of the abutment block 132, ensuring that it can only slide within the range defined by the sliding grooves 1142. During the unlocking process by pulling the handle 134, this ensures that the optical module 100 is completely detached from the cage 210 after the unlocking action is completed, avoiding the risk of the unlocking member 130 slipping off the shell 110.

[0042] like Figure 5 , Figure 6 and Figure 7 As shown, the abutment block 132 includes a base 1322 connected to the limiting part 1362, and a plurality of ribs 1324 formed on one side of the base 1322. The ribs 1324 have guide slopes 1324a for cooperating with the end of the tongue piece 212. A guide groove 1326 is formed between adjacent ribs 1324. The reinforcing member 120 has guide protrusions 122 corresponding to the ribs 1324. The guide grooves 1326 can slide along the guide protrusions 122.

[0043] Specifically, the design of the guide slope 1324a can more effectively guide the tongue 212 to deform or move when the supporting block 132 supports the tongue 212, making it easier to release the tongue 212 from the reinforcing member 120, reducing the force required for unlocking and improving the convenience of the unlocking operation. At the same time, the presence of the guide slope 1324a can also reduce friction between the tongue 212 and the supporting block 132, reducing wear caused by friction and extending the service life of the optical module 100 and the cage 210. In addition, the cooperation between the guide groove 1326 and the guide protrusion 122 allows the supporting block 132 to move along a fixed trajectory during sliding, further improving the stability and accuracy of the supporting block 132's movement. This cooperation method can effectively prevent the supporting block 132 from shifting or jamming during sliding, ensuring smooth unlocking operations, and also enhancing the connection strength and reliability between the reinforcing member 120 and the supporting block 132.

[0044] In an optional embodiment of this application, the limiting part 1362 is T-shaped or L-shaped, and the base 1322 is provided with an insertion groove 1322a and a snap-fit ​​groove 1322b located on at least one side of the insertion groove 1322a, so that the limiting part 1362 snaps into the snap-fit ​​groove 1322b.

[0045] Specifically, the T-shaped or L-shaped limiting part 1362, in conjunction with the insertion slot 1322a and snap-fit ​​slot 1322b on the base 1322, makes the assembly process of the limiting part 1362 and the base 1322 very simple and quick. During production, workers can easily snap the limiting part 1362 into the snap-fit ​​slot 1322b without the need for complex tools and processes, thus improving production efficiency and reducing production costs. In practical applications, the snap-fit ​​slot 1322b faces the inside of the housing 110. During the use of the optical module 100, the base 1322 is stopped by the reinforcing member 120 and the side wall of the housing 110, preventing the limiting part 1362 from detaching from the base 1322. This ensures the normal connection and operation between the components of the unlocking member 130, improving the stability and reliability of the unlocking structure of the optical module 100. When adapting to the T-shaped limiting part 1362, it is necessary to provide snap-fit ​​grooves 1322b on both sides of the insertion groove 1322a; when adapting to the L-shaped limiting part 1362, it is only necessary to provide snap-fit ​​grooves 1322b on one side of the insertion groove 1322a.

[0046] like Figure 4 As shown, a hook 1364 is provided on the connecting arm 136, and a groove 1144 is formed on the side wall of the bottom shell 114. The hook 1364 extends into the groove 1144, and an elastic member 1146 is provided in the groove 1144. The two ends of the elastic member 1146 abut against the hook 1364 and the side wall of the groove 1144 respectively, so that the connecting arm 136 is subjected to an elastic force that slides into the shell 110.

[0047] Specifically, the elastic element 1146 allows the connecting arm 136 to automatically reset after the unlocking operation, making the operation more convenient and faster, and improving the usability of the optical module 100. After inserting or removing the optical module 100, the user does not need to perform additional operations to restore the unlocking element 130 to its initial state, reducing operation steps and improving work efficiency. In addition, the cooperation of the hook 1364, the slot 1144, and the elastic element 1146 allows the connecting arm 136 to move more stably during sliding. The elastic element 1146 can buffer the impact force on the connecting arm 136 during sliding to a certain extent, while also ensuring the accuracy and reliability of the connecting arm 136 during unlocking and resetting, improving the overall stability of the unlocking structure of the optical module 100.

[0048] like Figure 4 and Figure 8 As shown, a limiting protrusion 1366 is formed on one side of the connecting arm 136 in the width direction, and a limiting groove 1162 corresponding to the limiting protrusion 1366 is formed on the top cover 116. The limiting protrusion 1366 is slidably held in the limiting groove 1162.

[0049] Specifically, the width of the limiting protrusion 1366 is smaller than the width of the limiting groove 1162. During the pulling of the handle 134, the limiting protrusion 1366 can slide a certain distance along the limiting groove 1162. Furthermore, during the reset process, the limiting protrusion 1366 can only slide within the range defined by the limiting groove 1162, thus preventing the unlocking component 130 from slipping off the housing 110 during the unlocking process. Simultaneously, it cooperates with the engagement of the supporting block 132 and the sliding groove 1142 to prevent excessive force concentration during the unlocking process of the optical module 100, thereby improving stability during use.

[0050] In an alternative embodiment of the application, the reinforcement 120 and the abutment block 132 are made of stainless steel, tool steel or die steel.

[0051] Specifically, the reinforcing member 120 and the retaining block 132, made of stainless steel, tool steel, or mold steel, have higher strength and hardness. During the insertion and unlocking of the optical module 100, they can better withstand the interaction forces with the tongue 212, reducing deformation and damage caused by scratching and squeezing. At the same time, these materials also have better wear resistance, effectively reducing wear between the optical module 100 and components such as the tongue 212, and extending the service life of the optical module 100 and the cage 210.

[0052] like Figures 9 to 12 As shown, this utility model also discloses an optical transceiver connection assembly 200, including a cage 210 and an optical module 100 from the aforementioned embodiments. The optical module 100 is pluggably connected to the cage 210. The cage 210 includes a housing 211 and tongues 212 disposed on opposite sides of the housing 211. The tongues 212 are bent inward toward the housing 211 to facilitate engagement with the reinforcing member 120 of the optical module 100. This optical transceiver connection assembly 200 has the same structure and beneficial effects as the optical module 100 in the aforementioned embodiments. The structure and beneficial effects of the optical module 100 have been described in detail in the aforementioned embodiments and will not be repeated here.

[0053] It should be noted that, Figure 9 This is a schematic diagram of the optical transceiver connection assembly 200 in the locked state. At this time, the end of the tongue 212 abuts against the reinforcing member 120 (please refer to...). Figure 10 This is to limit the movement of the optical module 100. Please refer to [further details]. Figure 11 When unlocking is required, pull handle 134 to cause the abutment block 132 to abut against the tongue 212, causing the tongue 212 to deform (see reference). Figure 12 The tongue 212 releases its limiting effect on the reinforcing member 120, thus allowing the optical module 100 to be easily removed from the cage 210.

Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
