Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to an MPO to MT adapter. Background Technology

[0002] MT (Mechanical Transfer) ferrules are mechanical adapters used with multi-fiber optic connectors. They offer numerous advantages, including high connection density, stable and reliable performance, compact size, ease of operation, and convenient cabling management, leading to their increasing use in high-density applications. MPO (Multi-fiber Push-On) connectors are push-in connectors that can connect multiple fibers simultaneously within a single connector. They support high-density cabling and multi-fiber parallel transmission, offering advantages such as high density and support for multi-fiber parallel transmission. They are widely used in data centers, high-speed optical modules, and other similar applications. In certain applications of fiber optic communication technology, MPO fiber optic connectors need to be directly connected to MT ferrules, thus requiring an MPO to MT adapter.

[0003] However, some existing MPO to MT adapters typically use elastic clips or screws or other fasteners, along with a cap and base, to lock the MT ferrule to the adapter. When using elastic clips, the clamping force is insufficient, resulting in poor tensile strength of the connection between the adapter and the MT ferrule. When using screws or other fasteners with a cap and base for locking, disassembly is required using tools such as screwdrivers, which is cumbersome, inefficient, and prone to damage to the screw holes after repeated use, leading to stripping and a short service life. Utility Model Content

[0004] The main purpose of this invention is to provide an MPO to MT adapter, which aims to improve the ease of installation and disassembly and tensile strength of the adapter when installing MT ferrules.

[0005] To achieve the above objectives, the MPO to MT adapter proposed in this utility model includes a housing, a first elastic buckle, and a cover. The housing has an MT socket and an MPO socket at opposite ends, respectively, and the MT socket communicates with the MPO socket. The MT socket has a first sidewall and a second sidewall arranged opposite to each other. The first sidewall has an opening, and the second sidewall has a backstop protrusion. The first elastic buckle is fixedly connected to the housing and located on one side of the opening. The cover is placed over the opening, and one end of the cover is engaged with the first elastic buckle. The end of the cover away from the first elastic buckle is rotatably connected to the housing. The cover is configured to rotate about the axial direction of the housing to expose or cover the opening.

[0006] In one embodiment, the MT socket further has a third sidewall, which connects the first sidewall and the second sidewall. The third sidewall has a stop protrusion that extends along the second sidewall to connect with the third sidewall. A limiting groove is formed between the stop protrusion, the third sidewall, and the stop protrusion. The limiting groove is used to prevent the MT core from moving axially along the housing.

[0007] In one embodiment, a backstop window is further provided on the first sidewall, and the sidewall of the backstop window is used to engage with the MT ferrule.

[0008] In one embodiment, a flexible connector is provided at the end of the cover away from the first elastic buckle. The flexible connector is connected to the housing and extends along the axial direction of the housing. The flexible connector is configured to cause the cover to rotate relative to the housing by deformation.

[0009] In one embodiment, the housing, the flexible connector, and the pressure cap are integrally formed.

[0010] In one embodiment, the pressure cap has an abutment protrusion on the side facing the MT insertion hole, the abutment protrusion being used to abut and limit the MT insertion core.

[0011] In one embodiment, the abutment protrusion is gradually tapered along the direction from the opening to the MT socket.

[0012] In one embodiment, the first elastic buckle includes a first elastic cantilever and a first limiting protrusion. The first elastic cantilever is connected to the housing and located on one side of the opening. The first elastic cantilever extends along the direction from the MT insertion hole to the opening. The first limiting protrusion is located on the side of the first elastic cantilever near the opening and engages with the pressure cap.

[0013] In one embodiment, the sidewall of the MPO socket is provided with a second elastic buckle. The second elastic buckle includes a second elastic cantilever and a second limiting protrusion. The second elastic cantilever is connected to the sidewall of the MPO socket and extends along the axial direction of the housing. The second limiting protrusion is provided on the side of the second elastic cantilever facing the MPO socket and is used to engage with the MPO connector.

[0014] In one embodiment, the housing, the second elastic cantilever, and the second limiting protrusion are integrally formed. Two spaced deformation seams are provided on one side wall of the MPO socket, and the second elastic cantilever is formed between the two deformation seams.

[0015] The MPO to MT adapter proposed in this utility model includes a housing, a first elastic buckle, and a cover. The housing has an MT socket and an MPO socket at opposite ends, respectively. The MT socket and the MPO socket are connected. The MT socket has a first sidewall and a second sidewall that are arranged opposite to each other. The first sidewall has an opening, and the second sidewall has a backstop protrusion. The first elastic buckle is fixedly connected to the housing and is located on one side of the opening. The cover is located on the opening. One end of the cover is engaged with the first elastic buckle, and the end of the cover away from the first elastic buckle is rotatably connected to the housing. The cover is configured to rotate about the axial direction of the housing to expose or cover the opening. When connecting the MT ferrule, rotate the cover around the connection point with the housing to expose the opening. The MT ferrule can then be inserted into the MTR socket through this opening. The anti-reverse protrusion abuts against the end of the MT ferrule furthest from the MPO socket, restricting the MT ferrule's axial movement along the housing. This effectively confines the MT ferrule within the MT socket, meaning the anti-reverse protrusion resists the tensile force transmitted from the optical fiber to the MT ferrule, preventing it from moving axially and detaching from the MT socket. This improves the tensile strength of the MPO to MT adapter. The cover, when engaged with the elastic clip, covers the opening, preventing the MT ferrule from detaching from the MT socket. Therefore, the double restraint of the cover and the anti-reverse protrusion ensures a secure connection between the MT ferrule and the housing. Furthermore, the cover can be unlocked by moving the elastic clip. This locking mechanism, where the cover rotates and engages with the elastic clip, makes MT ferrule installation and removal more convenient and quick, improving the ease and efficiency of MT ferrule installation.

[0035] This utility model proposes an MPO to MT adapter 100.

[0036] Please see Figures 1 to 3 In one embodiment of this utility model, the MPO to MT adapter 100 includes a housing 1, a first elastic buckle 2, and a cover 3. The housing 1 has an MT socket 1a and an MPO socket 1b at opposite ends, respectively. The MT socket 1a and the MPO socket 1b are connected. The MT socket 1a has a first sidewall and a second sidewall 12 arranged opposite to each other. The first sidewall has an opening 1a1, and the second sidewall 12 has a backstop protrusion 121. The first elastic buckle 2 is fixedly connected to the outer wall of the housing 1 and is located on one side of the opening 1a1. The cover 3 is placed on the opening 1a1. One end of the cover 3 is engaged with the first elastic buckle 2, and the end of the cover 3 away from the first elastic buckle 2 is rotatably connected to the housing 1. The cover 3 is configured to rotate about the axial direction of the housing 1 to expose or cover the opening 1a1.

[0037] In this embodiment, the housing 1 is the basic component of the entire adapter, serving to support and connect other components, including the MT ferrule 200 and the MPO connector 300. The housing 1 has a cylindrical structure with openings 1a1 at both ends. Each end has an MT ferrule 1a and an MPO ferrule 1b, which are interconnected to allow the MT ferrule 200 to mate with the MPO connector 300. The MT ferrule 1a on the housing 1 has a first sidewall and a second sidewall 12 arranged opposite each other. The first sidewall has an opening 1a1 for inserting the MT ferrule 200, and the second sidewall 12 has a retaining protrusion 121 (e.g., a retaining protrusion 121). Figure 3 As shown, Figure 3The dense dashed lines are only used to indicate the range of the anti-retraction protrusion 121 in this embodiment, which is used to limit the axial movement of the MT plug 200 and prevent it from dislodging from the MT socket 1a. The housing 1 may be made of engineering plastic with good mechanical strength and durability to ensure the overall stability and reliability of the adapter.

[0038] The first elastic buckle 2 is fixedly connected to the housing 1 and located on one side of the opening 1a1. Its structure is a buckle shape with a certain elastic deformation capability, and it can be made of engineering plastic or metal materials with good elastic properties. This material selection allows the buckle to undergo elastic deformation under external force, thereby achieving a snap-fit ​​engagement with the cover 3. One end of the elastic buckle is fixed to the housing 1, and the other end forms a free end with a snap-fit ​​part for engaging with the corresponding structure on the cover 3. When the cover 3 rotates to the position that covers the opening 1a1, the elastic buckle can fix the cover 3 by engaging with it through the snap-fit ​​part, preventing the cover 3 from rotating arbitrarily, thus ensuring that the opening 1a1 is stably covered and preventing the MT insert 200 from detaching from the opening 1a1.

[0039] A pressure cap 3 is placed over the opening 1a1, with one end engaging with the first elastic snap 2 and the other end rotatably connected to the housing 1. Specifically, the end of the pressure cap 3 away from the first elastic snap 2 is rotatably connected to the side of the housing 1 away from the first elastic snap 2 of the opening 1a1. The shape and size of the pressure cap 3 match the opening 1a1, partially or completely covering the opening 1a1 to meet the requirement of limiting the MT ferrule 200. In this embodiment, the opening 1a1 completely covers the first sidewall and is square in shape, therefore the first sidewall is not shown in the drawings, and the pressure cap 3 is adaptively square in shape. The rotatable connection end of the pressure cap 3 can be connected to the housing 1 by means of a shaft hole fit, that is, a shaft hole is provided at one end of the pressure cap 3, and a connecting shaft is provided at a corresponding position on the housing 1, and the rotation of the pressure cap 3 is realized by the fit between the shaft hole and the connecting shaft. The snap-fit ​​end of the cover 3 is provided with a snap-fit ​​structure that mates with the snap-fit ​​part of the first elastic snap 2. When the cover 3 is rotated to the appropriate position, the snap-fit ​​structure and the snap-fit ​​part snap together, thereby achieving a fixed connection between the cover 3 and the elastic snap. This structural design of the cover 3 allows it to rotate flexibly to expose or cover the opening 1a1, while achieving a stable locking state through the snap-fit ​​engagement with the elastic snap, ensuring the stability of the MT insert 200 after installation.

[0040] The engagement between the first elastic buckle 2 and the cover 3 is achieved by engaging the snap-fit ​​part of the elastic buckle with the free end of the cover 3, which is the end of the cover 3 furthest from its rotatable connection with the housing 1. When installing the MT insert 200, the cover 3 is first rotated around its rotatable connection with the housing 1 to expose the opening 1a1. At this time, the MT insert 200 can be inserted into the MT insertion hole 1a along the axial direction of the housing 1 from the opening 1a1, with the end of the MT insert 200 furthest from the MPO insertion port abutting against the anti-retraction protrusion 121. Subsequently, the cover 3 is rotated back to its original position, causing the free end of the cover 3 to engage with the snap-fit ​​part of the first elastic buckle 2, thereby fixing the cover 3 to the housing 1 and concealing the opening 1a1. This fitting method allows the cap 3 to be firmly fixed to the housing 1, preventing the MT ferrule 200 from detaching from the opening 1a1. Simultaneously, the elastic design of the snap-fit ​​allows the cap 3 to be unlocked by moving the snap-fit ​​when the MT ferrule 200 needs to be removed, enabling flexible rotation of the cap 3 and quick removal of the MT ferrule 200. The rotatable connection between the cap 3 and the housing 1 can be achieved by providing hole-shaft mating structures on both the cap 3 and the housing 1, by using an external hinge structure, or by using a flexible connector 31 to connect the cap 3 and the housing 1.

[0041] When the adapter in this embodiment is connected to the MT ferrule 200, please refer to [link / reference needed]. Figure 4 and Figure 5 The pressure cap 3 is rotated around its connection with the housing 1 to expose the opening 1a1. The MT ferrule 200 can then be inserted into the MTR socket through the opening 1a1. The anti-reverse protrusion 121 abuts against the end of the MT ferrule 200 furthest from the MPO socket, restricting the MT ferrule 200's axial movement along the housing 1. In other words, the MT ferrule 200 is confined within the MT socket 1a. The anti-reverse protrusion 121 resists the tensile force transmitted from the optical fiber to the MT ferrule 200, preventing it from moving axially along the housing 1 and detaching from the MT socket 1a. Therefore, the tensile strength of the MPO to MT adapter 100 is improved. After the pressure cap 3 engages with the elastic snap, it covers the opening 1a1, preventing the MT ferrule 200 from detaching from the MT socket through the opening 1a1. Therefore, with the dual restraint of the pressure cap 3 and the anti-reverse protrusion 121, a secure connection between the MT ferrule 200 and the housing 1 is achieved. Furthermore, the pressure cap 3 can be unlocked by moving the elastic buckle. The locking method in which the pressure cap 3 is rotatably connected to the housing 1 and engages with the elastic buckle makes the installation and removal of the MT ferrule 200 more convenient and quick, improving the convenience and efficiency of the MT ferrule 200 installation.

[0042] Further, please refer to Figure 3 and Figure 7In one embodiment of the present invention, the MT insertion hole 1a further has a third sidewall 13, the third sidewall 13 connects the first sidewall and the second sidewall 12, the third sidewall 13 is provided with a stop protrusion 131, the stop protrusion 121 extends along the second sidewall 12 to connect with the third sidewall 13, a limiting groove 13a is formed between the stop protrusion 121, the third sidewall 13 and the stop protrusion 131, the limiting groove 13a is used to prevent the MT insertion core 200 from moving along the axial direction of the housing 1.

[0043] In this embodiment, the MT socket 1a on the housing 1 has a first sidewall and a second sidewall 12 disposed opposite to each other. The first sidewall has an opening 1a1 for inserting the MT core 200. The second sidewall 12 has a retaining protrusion 121 for restricting the MT core 200's axial movement and preventing it from dislodging from the MT socket 1a. Further, the MT socket 1a also has a third sidewall 13, which connects the first sidewall and the second sidewall 12. The third sidewall 13 has a stop protrusion 131 to prevent the MT core 200 from moving axially toward the MPO socket 1b. The retaining protrusion 121 extends along the second sidewall 12 to connect with the third sidewall 13. A limiting groove 13a is formed between the retaining protrusion 121, the third sidewall 13, and the stop protrusion 131 (e.g., a positioning groove). Figure 3 As shown, Figure 3 The sparsely dotted lines are only used to indicate the range of the limiting groove 13a in this embodiment. The limiting groove 13a is used to prevent the MT ferrule 200 from moving axially along the housing 1. In practical applications, please refer to... Figure 7 Since the MT ferrule 200 has protrusions on both sides, the size and shape of the limiting groove 13a can be pre-set to accommodate the protrusions on both sides of the MT ferrule 200. When the MT ferrule 200 is inserted into the MT socket 1a from the opening 1a1, the protrusion is just locked into the limiting groove 13a. In this way, the inner wall of the limiting groove 13a can prevent the MT ferrule 200 from moving along the axial direction of the housing 1. This can prevent the connection between the MT ferrule 200 and the MPO connector 300 from becoming loose, and can also prevent the MT ferrule 200 from pushing the MPO ferrule and causing the MPO ferrule to detach from the housing 1 when it is pushed by the force.

[0044] Further, please refer to Figure 1 , Figure 3 and Figure 6 In one embodiment of the present invention, a backstop window 12a is also provided on the first side wall, and the side wall of the backstop window 12a is used to engage and limit the MT insert 200.

[0045] In this embodiment, the MT insertion hole 1a on the housing 1 has a first sidewall and a second sidewall 12 disposed opposite to each other. The first sidewall has an opening 1a1 for inserting the MT insert 200, and the second sidewall 12 has a retaining protrusion 121 for restricting the axial movement of the MT insert 200 and preventing it from dislodging from the MT insertion hole 1a. Furthermore, a retaining window 12a is also provided on the first sidewall, and the sidewall of the retaining window 12a is used to engage with the MT insert 200. Please refer to... Figure 6 In addition to the protrusions on the left and right sides, the MT ferrule 200 also has protrusions on the top and bottom sides. When installed with the MPO to MT adapter 100 of this embodiment, the lower protrusion engages with the thrust window 12a. The inner wall of the thrust window 12a prevents the MT ferrule 200 from moving axially or radially along the housing 1. Therefore, it not only prevents the connection between the MT ferrule 200 and the MPO connector 300 from becoming loose, but also prevents the MT ferrule 200 from pushing the MPO ferrule out of the housing 1 when subjected to thrust. At the same time, the inner wall of the thrust window 12a also prevents the MT ferrule 200 from shifting laterally during installation, thereby avoiding misalignment between the MT ferrule 200 and the MPO connector 300.

[0046] This embodiment further enhances the stability of the MT ferrule 200 within the housing 1 by providing a retaining window 12a on the first sidewall. The retaining window 12a and the MT ferrule 200 engage and limit each other, ensuring that after installation, the MT ferrule 200 is restricted not only axially by the retaining protrusion 121 and the limiting groove 13a, but also radially by the retaining window 12a, thus achieving omnidirectional limiting of the MT ferrule 200. This multi-dimensional limiting design significantly improves the reliability and stability of the connection between the MPO to MT adapter 100 and the MT ferrule 200, effectively preventing loosening or inaccurate mating caused by external forces or installation deviations, further enhancing the adapter's performance and reliability in practical applications. Furthermore, the retaining window 12a design also facilitates observation of the MT ferrule 200's installation status within the housing 1. Through the anti-reverse window 12a, operators can visually inspect whether the MT ferrule 200 is correctly installed, such as whether the MT ferrule 200 is fully inserted into the MT socket 1a and whether it correctly mates with the anti-reverse protrusion 121 and the limiting groove 13a. This visual installation inspection method greatly improves the accuracy and efficiency of installation, reduces connection problems caused by improper installation, and further enhances the reliability and stability of the adapter in practical applications.

[0047] Further, please refer to Figure 1 and Figure 4In one embodiment of the present invention, a flexible connector 31 is provided at the end of the cover 3 away from the first elastic buckle 2. The flexible connector 31 is connected to the housing 1 and extends along the axial direction of the housing 1. The flexible connector 31 is configured to cause the cover 3 to rotate relative to the housing 1 by deforming.

[0048] In this embodiment, the flexible connector 31 can be made of a material with a certain degree of flexibility, such as flexible plastic or rubber. The flexible connector 31 can undergo flexible deformation when subjected to external force, thereby enabling the flexible rotation of the pressure cap 3. Alternatively, the flexible connector 31 can be designed as an integrally formed structure with the housing 1 and the pressure cap 3, by creating a strip groove between the pressure cap 3 and the housing 1 to reduce the structural thickness and form the flexible connector 31. The flexible connector 31 extends axially along the housing 1, with one end fixedly connected to the pressure cap 3 and the other end fixedly connected to the housing 1. This structural design allows the flexible connector 31 to provide necessary support and guidance during the rotation of the pressure cap 3, while allowing the pressure cap 3 to rotate freely within a certain range.

[0049] The connection between the gland 3 and the housing 1 is achieved through the flexible connector 31, which not only simplifies the rotation structure of the gland 3 but also improves the flexibility and reliability of its rotation. Compared to rotation via a shaft structure, the flexible connector 31 reduces jamming caused by mechanical friction. Furthermore, the use of the flexible connector 31 reduces the precision requirements for the machining of the gland 3 and the housing 1, improving production efficiency and quality stability.

[0050] Please see Figure 1 and Figure 4 In one embodiment of this utility model, the shell 1, the flexible connector 31, and the pressure cap 3 are integrally formed.

[0051] In this embodiment, by designing the housing 1, flexible connector 31, and pressure cap 3 as a single-piece molding structure, such as through injection molding, the assembly steps and connection points between components are reduced, improving the overall strength and reliability of the product and reducing quality problems caused by assembly errors. The single-piece molding structure eliminates mechanical connection points between the flexible connector 31 and the housing 1 and pressure cap 3, preventing loosening or damage of connection points due to long-term use. Simultaneously, this design makes the rotation of the pressure cap 3 smoother and more flexible, as the transition between the flexible connector 31 and the pressure cap 3 and housing 1 is more natural, reducing jamming caused by mechanical friction or structural mismatch. Furthermore, the single-piece molding design improves the overall aesthetics of the adapter, making the product appearance simpler and more uniform. In addition, the single-piece molding design reduces the types and number of molds. Since the housing 1, flexible connector 31, and pressure cap 3 are integrally molded, only one mold is needed to complete the molding of the entire structure, thus reducing the types and number of molds. This not only lowers mold manufacturing costs but also reduces the complexity of mold management, further reducing production costs and improving production efficiency.

[0052] Further, please refer to Figure 1 and Figure 4 In one embodiment of the present invention, the pressure cap 3 is provided with an abutting protrusion 32 on the side facing the MT insertion hole 1a. The abutting protrusion 32 is used to abut and limit the MT insertion core 200.

[0053] In this embodiment, an abutment protrusion 32 is provided on the side of the pressure cap 3 facing the MT socket 1a, further enhancing the limiting effect of the MT ferrule 200 within the housing 1. When the MT ferrule 200 is installed into the MT socket 1a, the abutment protrusion 32 contacts the side of the MT ferrule 200 facing the opening 1a1, forming a limit. During adapter use, this prevents radial displacement of the MT ferrule 200 due to external forces, thereby ensuring a stable connection between the MT ferrule 200 and the MPO connector 300. Furthermore, the abutment protrusion 32 can extend into the opening 1a1 or the MT socket 1a to abut against the MT ferrule 200, preventing mismatch between the housing 1 and the MT ferrule 200 due to deformation or dimensional deviation, thus improving the adaptability of this MPO adapter to the MT ferrule 200.

[0054] Further, please refer to Figure 1 and Figure 4 In one embodiment of this utility model, the abutting protrusion 32 is gradually tapered along the direction from the opening 1a1 to the MT insertion hole 1a.

[0055] In this embodiment, the abutment protrusion 32 is gradually tapered along the direction from the opening 1a1 to the MT insertion hole 1a. Specifically, the abutment protrusion 32 is in the shape of an inverted trapezoid. When the pressure cap 3 rotates to cover the opening 1a1, the two sides of the inverted trapezoidal abutment protrusion 32 are inclined surfaces, which can avoid rubbing or interference with the inner walls on both sides of the opening 1a1, thus preventing the rotation of the pressure cap 3 from being jammed. It is understood that the inverted trapezoid in this embodiment is only an exemplary example, and other methods such as choosing an inverted frustum shape or using curved surfaces to replace the inclined surfaces on both sides of the inverted trapezoid can also be used.

[0056] Further, please refer to Figure 1 and Figure 4 In one embodiment of the present invention, the first elastic buckle 2 includes a first elastic cantilever 21 and a first limiting protrusion 22. The first elastic cantilever 21 is connected to the housing 1 and located on one side of the opening 1a1. The first elastic cantilever 21 extends along the direction from the MT insertion hole 1a to the opening 1a1. The first limiting protrusion 22 is located on the side of the first elastic cantilever 21 near the opening 1a1 and is engaged with the pressure cover 3.

[0057] In this embodiment, to enable the first elastic latch 2 to effectively fix and unlock the cover 3, the first elastic cantilever 21 extends along the direction from the MT insertion hole 1a to the opening 1a1, i.e., it is arranged radially along the housing 1. The first limiting protrusion 22 is located on the side of the first elastic cantilever 21 near the opening 1a1 and at the free end of the first elastic cantilever 21. The first limiting protrusion 22 has an abutting surface for engaging with the cover 3, and the other side of the first limiting protrusion 22 also has a guiding slope for guiding the cover 3 to slide to the side of the abutting surface. Compared with the traditional method of designing the cantilever along the axial direction of the housing 1 and directly using the elastic latch to engage the MT ferrule 200, the elastic latch in this embodiment is only used to prevent the cover 3 from rotating to prevent the MT ferrule 200 from disengaging from the opening 1a1. Therefore, even if the optical fiber is stretched, the elastic latch will not fail. The lateral thrust of the MT ferrule 200 on the cover 3 is much smaller than the tensile force transmitted by the optical fiber. Therefore, this setting is stable, reliable, simple and convenient.

[0058] Further, please refer to Figure 2 and Figure 3 In one embodiment of the present invention, the sidewall of the MPO socket 1b is provided with a second elastic buckle 14. The second elastic buckle 14 includes a second elastic cantilever 141 and a second limiting protrusion 142. The second elastic cantilever 141 is connected to the sidewall of the MPO socket 1b and extends along the axial direction of the housing 1. The second limiting protrusion 142 is provided on the side of the second elastic cantilever 141 facing the MPO socket 1b and is used to engage with the MPO connector 300.

[0059] In this embodiment, to effectively achieve the fixing and unlocking functions of the MPO connector 300, a second elastic buckle 14 is provided on each of the opposite side walls of the MPO socket 1b. The second elastic cantilever 141 is connected to the side wall of the MPO socket 1b and extends axially along the housing 1. A second limiting protrusion 142 is provided at the free end of the second elastic cantilever 141. Since the second elastic cantilever 141 extends axially along the housing 1, guide slopes are provided on both sides of the second limiting protrusion 142 for easy disassembly. When the pulling force is sufficiently large, guided by the guide slopes, the two elastic cantilever arms gradually open, causing the second limiting protrusion 142 to disengage from the MPO connector 300, thereby disengaging the MPO connector 300 from the MPO socket 1b. This design makes the installation and disassembly of the MPO connector 300 more convenient and faster, reduces the risk of damage due to improper operation, and ensures the stability and reliability of fiber optic communication.

[0060] Further, please refer to Figure 2 and Figure 3 In one embodiment of the present invention, the housing 1, the second elastic cantilever 141 and the second limiting protrusion 142 are integrally formed structures. Two deformation seams 1b1 are provided on one side wall of the MPO socket 1b, which are spaced apart from each other, and the second elastic cantilever 141 is formed between the two deformation seams 1b1.

[0061] In this embodiment, a second elastic cantilever 141 is formed by providing two deformation seams 1b1 on one side wall of the MPO socket 1b. The second elastic cantilever 141 forms part of the side wall of the MPO socket 1b, which not only allows the second elastic buckle 14 to be hidden inside the housing 1, reducing space occupation, but also facilitates wiring and installation in high-density usage scenarios. At the same time, the one-piece molding design reduces the number of parts and assembly steps in the production process, saves materials, and reduces production costs.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
