Description

Technical Field

[0001] The utility model belongs to the field of optical modules, and in particular relates to an optical module equipped with a detachable pull ring. Background Art

[0002] The optical module is a key optoelectronic device in the optical fiber communication system. It is mainly responsible for the functions of photoelectric and electro-optical conversion. Specifically, the transmitting end of the optical module converts the electrical signal into an optical signal, transmits it through the optical fiber, and then converts the optical signal back to an electrical signal at the receiving end.

[0003] The optical module is usually provided with a pull ring, which is used to adapt to the unlocking mechanism on the system mainboard, so that the optical module can be stably installed and separated from the system mainboard.

[0004] In the prior art, when the pull ring needs to be installed on the optical module, there are mainly two installation methods. The first installation method is: after the upper shell and the lower shell of the optical module are assembled with each other, the pull ring is installed on the assembled optical module shell. The second installation method is: when the upper shell and the lower shell of the optical module are assembled with each other, the pull ring is installed at the connection between the upper shell and the lower shell of the optical module.

[0005] However, the applicant has found in practice that both of the above two installation methods have some shortcomings. In the first installation method, when the optical module needs to be disassembled, the pull ring must be disassembled as well, which is more cumbersome; in the second installation method, when the pull ring needs to be replaced, the upper shell and the lower shell must be separated, which affects the accuracy of the optical module.

[0006] Therefore, there is an urgent need in the prior art for an optical module that can overcome the shortcomings of the above two methods. Utility Model Content

[0007] The utility model provides an optical module, which aims to solve the shortcomings of the pull ring assembly method in the prior art.

[0008] In order to achieve the above object, the utility model provides an optical module equipped with a detachable pull ring, comprising:

[0009] An optical module housing, the optical module housing comprising a first shell and a second shell, the first shell and the second shell are detachably connected, and the first shell is configured with a mounting groove;

[0010] A pull ring, wherein the pull ring includes an unlocking piece, and the unlocking piece can be detachably installed in the installation groove.

[0011] In this solution, the pull ring is installed on the first shell, and the pull ring is detachably installed. Therefore, when the pull ring needs to be disassembled, it can be directly removed from the first shell without separating the first shell from the second shell, thereby avoiding the misalignment of the optical device that has been debugged inside the optical module housing. At the same time, when the first shell needs to be separated from the second shell, since the pull ring is installed on the first shell, the pull ring will not be separated when the first shell is separated from the second shell.

[0012] In summary, the present solution solves the problem in the prior art that when the pull ring is disassembled, the shell is also disassembled, or when the shell is disassembled, the pull ring is also disassembled through the above-mentioned design.

[0013] Preferably, in order to allow the unlocking piece to smoothly enter the installation slot, the unlocking piece will not be blocked by the side of the optical module housing. In this solution, the unlocking piece is preferably an elastic piece.

[0014] Preferably, in order to make the connection between the pull ring and the optical module housing more stable, the unlocking pieces described in this solution are provided with two; installation grooves are respectively constructed on both sides of the first shell, and the two unlocking pieces can be respectively adapted to the installation grooves on both sides of the first shell.

[0015] In this solution, the pull ring is connected to the optical module housing through two unlocking pieces. Obviously, compared with only one unlocking piece connected to the optical module housing, the connection between the pull ring and the optical module housing is achieved by connecting two unlocking pieces, and the connection is more stable, and the pull ring and the optical module housing are not easy to be separated.

[0016] At the same time, since unlocking pieces are provided on both sides, the optical module housing is located between the unlocking pieces on both sides. Therefore, when the pull ring moves to either side, the pull ring will be restricted by the corresponding unlocking piece, and the connection between the pull ring and the optical module is more stable.

[0017] In order to allow the user to operate the pull ring, the pull ring of this solution includes a ring mouth portion, and the two unlocking pieces are fixedly connected to the ring mouth portion. The pull ring of this solution is provided with a ring mouth portion connected to the unlocking piece. When the user manipulates the ring mouth portion, the mouth portion can drive the unlocking piece to move, and the movement of the unlocking piece realizes the unlocking of the optical module.

[0018] Preferably, since the unlocking piece needs to move to unlock the optical module, in order to ensure that the unlocking piece will not be applied to a position separated from the optical module housing when the unlocking piece moves, the solution preferably has a restraining piece configured on the unlocking piece, and a restraining groove is configured inside the mounting groove, the size of the restraining groove is larger than the size of the restraining piece, the restraining groove can accommodate the restraining piece, and can limit the movement position of the restraining piece.

[0019] In this solution, when the unlocking piece is accommodated in the installation groove, the restraining piece is also accommodated in the restraining groove. When the unlocking piece moves to unlock, the restraining piece also moves. Since the restraining piece can only move in the restraining groove, the movement position of the restraining piece is obviously restricted, which in turn leads to the movement position of the unlocking piece being restricted. The unlocking piece cannot move to a position separated from the installation groove, which ensures the stable connection between the pull ring and the optical module housing.

[0020] Preferably, in order to ensure that the unlocking piece can be accurately assembled into the installation slot and the unlocking piece can be withdrawn from the installation slot, the unlocking piece of this solution is configured with a blocking piece; the first housing is configured with a guide groove, the guide groove is connected to the installation slot, and the blocking piece moves along the guide groove, so that the blocking piece is installed in / out of the installation slot.

[0021] When the blocking piece of the unlocking piece structure in this solution moves along the guide groove, the guide groove guides the blocking piece to move, so that the unlocking piece can be accurately assembled into the installation groove. At the same time, when the unlocking piece needs to be taken out, it only needs to move the unlocking piece along the guide groove, and the unlocking piece can be withdrawn from the installation groove. Through the above design, the pull ring can be assembled quickly and accurately, and the assembly efficiency can be improved.

[0022] Preferably, the unlocking piece needs to be unlocked by movement. In order to ensure that the unlocking piece can automatically return to its original position after the movement, the unlocking piece can stably match with the locking mechanism on the system motherboard when the unlocking piece is used again. The mounting slot of the present solution is internally configured with a return slot, in which a return spring is installed; the return slot is connected to the guide slot, the baffle moves along the guide slot, the baffle enters / exits the return slot, and the baffle is used to match with the return spring.

[0023] In this solution, the return slot can accommodate a return spring. After the unlocking piece is installed in the installation slot, the baffle piece fits with the return spring in the return slot. Therefore, when the unlocking piece moves to unlock, the return spring is in a compressed state. The return spring rebounds to drive the unlocking piece back to its original position. The unlocking piece after returning to its original position can ensure that the optical module fits and connects with the locking structure on the system motherboard next time.

[0024] Preferably, in order to prevent the unlocking piece from being in the unlocking position, the unlocking piece is adapted to the mounting groove. In this solution, the connection between the guide groove and the return groove is located at the unlocking end of the return groove.

[0025] In this solution, when the unlocking piece needs to be unlocked, the blocking piece needs to move to the position of the guide slot and exit the installation slot through the guide slot. However, the connection between the guide slot and the return slot is located at the unlocking end of the return slot, so that when the unlocking piece is in the locked state, the unlocking piece will not be separated from the installation slot from the position of the guide slot. At the same time, when the blocking piece moves to the position of the guide slot due to unlocking, the return spring will drive the blocking piece to return, so the blocking piece will not exit the installation slot from the position of the guide slot.

[0026] Preferably, when the unlocking piece is installed inside the installation slot, if there is no restriction on the unlocking piece, the front end of the unlocking piece is easily separated from the installation slot. Therefore, the unlocking piece of this solution is configured with a limiting portion, and the optical module housing is configured with a limiting slot adapted to the limiting portion, and the limiting portion is adapted to the limiting slot, so that the unlocking piece is restricted in the installation slot and can guide the unlocking piece to move.

[0027] In this solution, by providing mutually adapted limiting parts and limiting grooves, the limiting parts and limiting grooves are mutually limited, so that the unlocking piece is stably installed inside the installation groove. At the same time, when the unlocking piece moves inside the installation groove, the limiting parts and limiting grooves can also be mutually adapted and guided, so that the unlocking piece moves more accurately.

[0028] Preferably, in order to ensure a more stable connection between the unlocking piece and the mounting slot, the unlocking piece of the present solution is configured with two or more limiting portions.

[0029] By constructing two or more limiting portions, the unlocking piece can achieve a more stable connection with the installation groove through the two or more limiting portions.

[0030] In order to allow the limiting part to be assembled into the limiting groove and to exit the limiting groove when the unlocking piece exits the installation groove, the optical module housing described in this scheme is constructed with an assembly port, which is connected to the limiting groove and is used for the limiting part to enter / exit the limiting groove.

[0031] This solution realizes the assembly of the limiting part into the limiting groove by setting the assembly opening, and the limiting part withdraws from the limiting groove when the unlocking piece withdraws from the installation groove, thereby preventing the limiting part from withdrawing from the limiting groove.

[0032] Preferably, in order to ensure that the limiting portion and the limiting groove will not separate when the unlocking piece is located at the locking position, the assembly port is preferably configured at the unlocking end of the limiting groove.

[0033] The beneficial effect of the utility model is that: in this solution, the pull ring is installed on the first shell, and the pull ring is detachably installed. Therefore, when the pull ring needs to be disassembled, the pull ring can be directly removed from the first shell without separating the first shell from the second shell, thereby avoiding the misalignment of the optical device that has been debugged inside the optical module housing. At the same time, when the first shell needs to be separated from the second shell, since the pull ring is installed on the first shell, the pull ring will not be separated when the first shell is separated from the second shell.

[0034] In summary, this solution solves the shortcomings of the pull ring installation method in the prior art through the above-mentioned design. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are only examples of devices and methods consistent with some aspects of the present disclosure as detailed in the attached claims.

[0041] It should be noted that all actions to obtain signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0042] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", are defined according to the corresponding parts' own contours. The terms used in the present disclosure, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance.

[0043] Basically as attached Figure 1 As shown, an optical module equipped with a detachable pull ring can realize that when the pull ring 2 needs to be removed, the housing does not need to be removed; at the same time, when the optical module housing needs to be removed, the pull ring 2 does not need to be removed. The shortcomings of the pull ring 2 assembly method in the prior art can be solved.

[0044] like Figure 1 As shown, the optical module equipped with a detachable pull ring 2 in the embodiment of the present disclosure specifically includes an optical module housing 1 and a pull ring 2. The optical module housing 1 includes a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 can be connected by upper and lower assembly to assemble to form an optical module housing. Relevant optical devices can be installed inside the optical module housing 1. The specific model of the optical device is determined by the signal of the optical module, and the embodiment of the present disclosure does not limit it. The first shell 11 and the second shell 12 can be detachably connected by configuring fasteners or buckles during implementation.

[0045] In the embodiment of the present disclosure, preferably, mounting grooves 13 are configured on both the front and rear sides of the first housing 11. The mounting grooves 13 are linear grooves and are arranged along the length direction of the first housing 11. The mounting grooves 13 can be adapted to the unlocking piece 22 in the pull ring 2, so that the pull ring 2 can be installed on the first housing 11. Figure 1 shown.

[0046] It is understandable that: in the embodiment of the present disclosure, the mounting groove 13 is set in the first shell 11, but obviously, in some other embodiments, the mounting groove 13 can also be installed in the second shell 12. At the same time, the mounting groove 13 can be completely only set in the first shell 11. However, in some other embodiments, one side wall of the mounting groove 13 can also be the side of the second shell 12, that is, the inner bottom and one side wall of the mounting groove 13 are constructed in the first shell 11, and the other side wall of the mounting groove 13 is the side wall of the second shell 12, such as Figure 3 and Figure 4 shown.

[0047] In the embodiment of the present disclosure, the pull ring 2 is installed in the installation groove 13 and is detachably installed. Therefore, when the first shell 11 and the second shell 12 need to be separated, since the pull ring 2 is installed in the installation groove 13, the pull ring 2 will not be removed at the same time. Figure 3As shown in the figure. When it is necessary to separately disassemble the pull ring 2, since the pull ring 2 is detachably installed, it is not necessary to disassemble the optical module housing 1 either.

[0048] As Figure 2 shown, in the embodiment of the present disclosure, the pull ring 2 includes a ring mouth portion 21 and two unlocking pieces 22. The two unlocking pieces 22 are symmetrically arranged, and the tails of the two unlocking pieces 22 are fixedly connected to the ring mouth portion 21. In the embodiment of the present disclosure, the pull ring 2 can be integrally formed, or the unlocking pieces 22 and the ring mouth portion 21 can be separately manufactured, and then the unlocking pieces 22 and the ring mouth portion 21 are connected together by means of welding, plugging fasteners, etc. In the embodiment of the present disclosure, the ring mouth portion 21 is specifically in a square shape, and the ring mouth portion 21 is used for the user to pull, so as to drive the unlocking pieces 22 to move.

[0049] In the embodiment of the present disclosure, the unlocking piece 22 is specifically made of a metal material, and can specifically be made of iron or steel. The unlocking pieces 22 are distributed in a V shape, and the unlocking pieces 22 can be driven by an external force to deform and can automatically rebound to the undeformed state. Therefore, when it is necessary to install the pull ring 2 into the installation groove 13. First, the user places the optical module housing 1 between the two unlocking pieces 22 on both sides. Then, the unlocking pieces 22 move towards the position of the installation groove 13. After the unlocking pieces 22 reach the position adapted to the installation groove 13, the unlocking pieces 22 are pressed into the installation groove 13 by an external force. Similarly, when it is necessary to separate the unlocking pieces 22 from the installation groove 13, the unlocking pieces 22 automatically rebound into a V shape, the unlocking pieces 22 are separated from the installation groove 13, and then the pull ring 2 is separated from the optical module housing 1.

[0050] Alternatively, in some embodiments, the two unlocking pieces 22 can also be arranged in parallel, and the unlocking pieces 22 can also be driven by an external force to deform and can automatically rebound to the undeformed state. Therefore, when it is necessary to install the pull ring 2 into the installation groove 13. First, the user drives the two unlocking pieces 22 on both sides to deform into a V shape by an external force, and makes the optical module housing 1 located between the two unlocking pieces 22 on both sides. Then, the unlocking pieces 22 move towards the position of the installation groove 13. After the unlocking pieces 22 reach the position adapted to the installation groove 13, the unlocking pieces 22 rebound, and the unlocking pieces 22 are inserted into the installation groove 13. Similarly, when it is necessary to separate the unlocking pieces 22 from the installation groove 13, the user also deforms the unlocking pieces 22 by an external force, and the unlocking pieces 22 are separated from the installation groove 13.

[0051] As Figure 2 shown, in the embodiment of the present disclosure, the specific structure of the unlocking piece 22 includes an unlocking protrusion 221, a retaining piece 222, a limiting portion and a restraining piece 225. At the same time, as Figure 3 and Figure 4As shown, the optical module housing 1 is also configured with a return groove 15 adapted to the blocking piece 222 , a limiting groove adapted to the limiting portion, and a restraining groove 18 adapted to the restraining piece 225 .

[0052] like Figure 2 As shown, in the embodiment of the present disclosure, the unlocking protrusion 221 is located at the front end of the unlocking piece 22. The unlocking protrusion 221 can be formed by bending the front end of the unlocking piece 22 outward, and the front end of the unlocking piece 22 forms an unlocking protrusion 221 protruding outward. The unlocking protrusion 221 is used to cooperate with the locking mechanism on the system motherboard to achieve locking and unlocking of the optical module. When the unlocking protrusion 221 is in the locked position, the front end of the unlocking protrusion 221 can contact the front end of the mounting groove 13 to limit the unlocking piece 22.

[0053] like Figure 2 to Figure 4 As shown, the blocking piece 222 in the embodiment of the present disclosure is arranged at the rear middle part of the unlocking piece 22. The blocking piece 222 can be mounted on the unlocking piece 22 by welding, or an arc-shaped bending opening can be constructed in the middle of the unlocking piece 22, and the bending opening is bent to form the blocking piece 222. The blocking piece 222 is specifically used to adapt to the return spring (the return spring is not shown in the figure), to ensure that the return spring can be driven by the pull ring 2 to deform, and to drive the pull ring 2 to return when the return spring rebounds. In order to achieve adaptation with the blocking piece 222, the optical module housing is constructed with a return groove 15, which is located at the inner bottom of the mounting groove 13, and the return groove 15 can be a rectangular groove. At the same time, the first shell 11 is also constructed with a vertically arranged guide groove 14. The guide groove 14 is in a connected state with the inside of the return groove 15.

[0054] Take an application scenario as an example: when the unlocking piece 22 is installed, the blocking piece 222 moves along the guide groove 14. The guide groove 14 can guide the blocking piece 222 so that the unlocking piece 22 is guided. At the same time, the guide groove 14 can also prevent the blocking piece 222 from interfering with the optical module housing 1. Finally, the blocking piece 222 enters the return groove 15 along the guide groove 14 and is accommodated in the return groove 15. It can be understood that: in the above process, since the guide groove 14 plays a guiding role for the blocking piece 222, and since the blocking piece 222 is located on the unlocking piece 22, the guide groove 14 also plays a guiding role for the entire unlocking piece 22, ensuring that the unlocking piece 22 can be accurately moved into the installation groove 13.

[0055] like Figure 2 to Figure 4As shown, in order to facilitate the installation of the return spring, an installation opening 226 is also configured on the unlocking piece 22 in the disclosed embodiment. When the blocking piece 222 is located in the return groove 15, the installation opening 226 is directly opposite to the return groove 15. Therefore, the return spring can be installed into the return groove 15 through the installation opening 226. In other words, the return spring is installed after the blocking piece 222 is installed in place through the installation opening 226. This design solves the problem that the return spring will hinder the installation of the blocking piece 222 if the return spring is installed first.

[0056] At the same time, in the disclosed embodiment, it is also preferred that the connection between the guide groove 14 and the return groove 15 is located at the unlocking end of the return groove 15. The unlocking end of the return groove 15 is the other end where the blocking piece 222 is located when the unlocking piece 22 is in the locked position. By setting the connection between the guide groove 14 and the return groove 15 at the unlocking end of the return groove 15, when the unlocking piece 22 is in the locked position, the blocking piece 222 will not withdraw from the guide groove 14, and the unlocking piece 22 will not be separated from the mounting groove 13. At the same time, even if the blocking piece 222 is moved to the unlocking end of the return groove 15, since the blocking piece 222 drives the return spring to be in a compressed state, the return spring will drive the blocking piece 222 to move toward the locking end of the return groove 15, and the blocking piece 222 will not withdraw from the guide groove 14. Through the above design, the probability of the unlocking piece 22 being disengaged from the mounting groove 13 is lower, and the installation of the unlocking piece 22 is more stable.

[0057] The limiting part in the embodiment of the present disclosure is arranged at the edge of the unlocking piece 22, and the limiting part is specifically a limiting protrusion, and the shape of the limiting protrusion is rectangular. At the same time, a limiting groove for adapting the limiting part is also configured on the optical module housing. The shape of the limiting groove is adapted to the limiting part, so that after the unlocking piece 22 is installed inside the mounting groove 13, the unlocking piece 22 and the mounting groove 13 will not be separated. At the same time, when the unlocking piece 22 performs telescopic movement, the limiting part and the limiting groove cooperate to play a guiding role, so that the unlocking piece 22 moves more accurately and the unlocking piece 22 will not be offset.

[0058] like Figure 2 to Figure 4 As shown, the limiting portion in the embodiment of the present disclosure specifically includes a first limiting portion 223 and a second limiting portion 224, and the first limiting portion 223 is located at the front end of the second guide portion. The limiting groove specifically also includes a first limiting groove 16 and a second limiting groove 17, and the first limiting groove 16 is located at the front end of the second limiting groove 17. The first limiting portion 223 is adapted to the first limiting groove 16, and the second limiting portion 224 is adapted to the second limiting groove 17. At least two positions on the unlocking piece 22 are limited and guided, and the unlocking piece 22 is more stable.

[0059] The first limiting portion 223 in the disclosed embodiment is preferably disposed at the upper and lower edges of the unlocking piece 22, and the first limiting portion 223 may be formed by protruding outward from the upper and lower edges of the unlocking piece 22. At the same time, the first limiting grooves 16 corresponding to the first limiting portion 223 are also respectively disposed on the upper and lower side walls of the mounting groove 13. The first limiting portion 223 at the upper and lower edges is adapted to the first limiting grooves 16 at the upper and lower sides of the mounting groove 13, thereby limiting the upper and lower sides of the unlocking piece 22.

[0060] The second limiting portion 224 in the disclosed embodiment is disposed at the lower edge of the unlocking piece 22, and the second limiting portion 224 can be formed by bending the lower end of the unlocking piece 22. At the same time, the inner bottom side surface of the mounting groove 13 is correspondingly configured with the second limiting groove 17. When the unlocking piece 22 is installed inside the mounting groove 13, the second limiting portion 224 is accommodated inside the second limiting groove 17. The second limiting portion 224 and the second limiting groove 17 are adapted to limit the lower end of the unlocking piece 22.

[0061] It should be noted that: in the embodiment of the present disclosure, two limiting portions and two limiting grooves are provided, but obviously, in some other embodiments, more than two limiting portions and limiting grooves may be provided.

[0062] In order to facilitate the assembly and separation of the first limiting portion 223 and the first limiting groove 16, and to facilitate the assembly and separation of the second limiting portion 224 and the second limiting groove 17. Therefore, in the embodiment of the present disclosure, the first limiting groove 16 and the second limiting groove 17 are respectively configured with the first assembly port 161 and the second assembly port 171. The first assembly port 161 and the second assembly port 171 are in a connected state with the first limiting groove 16 and the second limiting groove 17, respectively. In addition, the first assembly port 161 and the second assembly port 171 are respectively located at the unlocking end of the first limiting groove 16 and the second limiting groove 17. When the unlocking end of the first limiting groove 16 and the second limiting groove 17, that is, the unlocking piece 22 is located at the locking position, the first limiting groove 16 is located at the other end of the end where the first limiting portion 223 is located, and the second limiting groove 17 is located at the other end of the end where the second limiting portion 224 is located.

[0063] Take an application scenario as an example: when assembling the unlocking piece 22, the first limiting part 223 and the second limiting part 224 can be assembled from the corresponding first assembly port 161 and the second assembly port 171 respectively, and the first limiting part 223 and the second limiting part 224 enter the first limiting groove 16 and the second limiting groove 17; when the unlocking piece 22 needs to be taken out, the first limiting part 223 and the second limiting part 224 can also be withdrawn from the corresponding first assembly port 161 and the second assembly port 171 respectively. At the same time, since the first assembly port 161 and the second assembly port 171 are the unlocking ends of the first limiting groove 16 and the second limiting groove 17, when the unlocking piece 22 is in the locked position, the first limiting part 223 and the second limiting part 224 will not separate from the first limiting groove 16 and the second limiting groove 17, and the installation of the unlocking piece 22 is more stable.

[0064] like Figure 2 to Figure 4 As shown, the constraint piece 225 in the disclosed embodiment is arranged in the middle of the unlocking piece 22, specifically between the first limiting portion 223 and the second limiting portion 224. The constraint piece 225 in the disclosed embodiment is formed by constructing an arc-shaped bending opening in the middle of the unlocking piece 22, and then bending the bending opening. At the same time, a constraint groove 18 is arranged at the inner bottom of the mounting groove 13. When the unlocking piece 22 is installed inside the mounting groove 13, the constraint piece 225 is located in the constraint groove 18. When the unlocking piece 22 performs telescopic movement, the constraint piece 225 moves inside the constraint groove 18.

[0065] At the same time, it should be noted that when the unlocking piece 22 moves to the unlocking position, the restraining piece 225 is blocked by the side wall of the restraining groove 18, and the unlocking piece 22 cannot continue to move. At this time, the limiting part has not moved to the assembly port, and the blocking piece 222 has not moved to the guide groove 14. Therefore, the limiting part will not be disengaged from the limiting groove at the assembly port, the blocking piece 222 will not move along the guide groove 14, and then the unlocking piece 22 will not be separated from the installation groove 13. In other words, the restraining piece 225 in the embodiment of the present disclosure plays a locking function for the unlocking piece 22. When the unlocking piece 22 needs to be separated from the installation groove 13, the restraining piece 225 needs to be deformed by external force first, so that the restraining piece 225 can withdraw from the restraining groove 18, and then the limiting part can move to the assembly port, the blocking piece 222 can move to the guide groove 14, and the unlocking piece 22 can be separated from the installation groove 13.

[0066] The following is a further detailed description through a specific implementation method: First, the first shell 11 is connected to the second shell 12, and the first shell 11 and the second shell 12 are combined to form an optical module housing 1. Then, the optical module housing 1 is placed between the unlocking pieces 22 on both sides so that the blocking piece 222 is aligned with the guide groove 14. Then, the unlocking piece 22 is precisely moved toward the position of the mounting groove 13 through the guidance of the blocking piece 222. After the unlocking piece 22 reaches the position that matches the mounting groove 13, the unlocking piece 22 is assembled into the interior of the mounting groove 13. Finally, the unlocking piece 22 is pushed forward so that the restraining piece 225 in the unlocking piece 22 enters the restraining groove 18, and the unlocking piece 22 is restricted by the restraining groove 18.
