Description

Technical Field

[0001] This utility model relates to the field of fiber optic connector technology, and in particular to an MPO connector. Background Technology

[0002] MPO (Multi-fiber Push On) connectors are a type of fiber optic connector that enables the connection of multiple fiber cores within a single connector, greatly increasing fiber density. They are commonly used to meet the needs of fiber optic cable connections in high-speed, high-capacity optical communication systems.

[0003] Existing MPO connectors typically include an inner frame with a through-cavity, an outer frame that is movably fitted outside the inner frame, and a return spring located in the gap between the inner and outer frames to elastically push the outer frame towards the front end of the inner frame. To connect the inner frame to the adapter, the outer wall of the inner frame also has a snap-fit ​​groove for engaging with the corresponding hook of the adapter. When the MPO connector is connected to the adapter, the adapter's hook is located within the snap-fit ​​groove, and the outer frame, under the elastic force of the return spring, covers the snap-fit ​​groove, locking the MPO connector onto the adapter. When it is necessary to unlock the MPO connector from the adapter to remove the MPO connector, the assembler pulls the outer frame backward, causing it to move backward relative to the inner frame, exposing the snap-fit ​​groove of the inner frame. At this point, the adapter can disengage from the inner frame. Further pulling the outer frame backward completes the disengagement of the MPO connector from the adapter.

[0004] However, when multiple MPO connectors are connected to the adapter, the MPO connector's mating components are inserted into the corresponding connection holes of the adapter. Because the connection holes of the adapter are relatively close together, the MPO connectors are also very close together, making it difficult for operators to directly manipulate the outer frame to unlock the MPO connectors and adapters. If a separate drive mechanism is used to operate the outer frame to unlock the MPO connectors and adapters, accidental activation of this mechanism can easily lead to mis-locking of the MPO connectors and adapters.

[0005] Therefore, there is an urgent need for an MPO connector to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an MPO connector that facilitates the unlocking operation of the MPO connector and adapter without increasing the probability of mis-locking between the MPO connector and adapter.

[0007] To achieve this objective, the present invention adopts the following technical solution: An MPO connector, comprising: The inner frame sleeve has a first end and a second end that are disposed opposite to each other along a first direction, and the outer wall of the inner frame sleeve is provided with a snap-fit ​​groove. An outer frame sleeve is fitted over the middle of the inner frame sleeve; A reset spring is disposed between the inner frame sleeve and the outer frame sleeve, and is used to push the outer frame sleeve towards the first end so that the outer frame sleeve covers the buckle groove; Tail sleeve, located at the second end of the inner frame sleeve; A connecting plate has one end fixedly connected to the end of the outer frame sleeve near the tail sleeve, and the other end extends towards the tail sleeve. One of the tail sleeve and the connecting plate is provided with a connecting protrusion, and the other is provided with a connecting groove. The tail sleeve can rotate relative to the outer frame sleeve so that the connecting protrusion enters and leaves the connecting groove. When the connecting protrusion is located in the connecting groove and the tail sleeve moves away from the first end, the connecting protrusion can drive the outer frame sleeve to move away from the first end through the connecting plate.

[0008] As an improvement to the above technical solution, the connecting groove is disposed on the connecting plate, and the connecting protrusion is disposed on the tail sleeve.

[0009] As an improvement to the above technical solution, the connecting protrusions are fixedly provided on both sides of the tail sleeve, and the connecting plates are provided one-to-one with the connecting protrusions. The connecting plates are provided with connecting grooves, and the grooves of the connecting grooves of the two connecting plates face opposite directions. When the tail sleeve rotates relative to the outer frame sleeve, the connecting protrusions located on both sides of the tail sleeve can respectively enter the connecting grooves on the corresponding connecting plates.

[0010] As an improvement to the above technical solution, the two connecting plates are symmetrically arranged on the end face of the outer frame sleeve near the tail sleeve.

[0011] As an improvement to the above technical solution, a positioning groove for accommodating the connecting protrusion is provided on the side wall of the connecting groove away from the outer frame sleeve.

[0012] As an improvement to the above technical solution, there is a gap between the side wall of the tail sleeve and the connecting plate.

[0013] As an improvement to the above technical solution, the MPO connector further includes a base, which is fixedly disposed on the side wall of the tail sleeve. The base and the connecting protrusion are respectively disposed in a one-to-one correspondence, and the connecting protrusion is fixedly disposed on the corresponding base.

[0014] As an improvement to the above technical solution, the length direction of the connecting plate is along the first direction, and the connecting plate is an arc-shaped plate.

[0015] As an improvement to the above technical solution, the MPO connector further includes: A stopper includes a stop body, a cantilever, and a support sleeve. The cantilever is connected to the stop body and extends along a first direction and protrudes from the stop body. One end of the cantilever protruding from the stop body is connected to the inner frame sleeve. The support sleeve is fixedly disposed at the end of the stop body away from the cantilever. A protective sleeve is fitted onto the support sleeve, and a tail sleeve is fitted onto the protective sleeve. The tail sleeve is rotatable relative to the protective sleeve and can move relative to the protective sleeve along the first direction.

[0016] As an improvement to the above technical solution, a clearance groove is provided on the side wall of the connecting groove near the outer frame sleeve. The clearance groove is located at the bottom of the connecting groove and extends along the first direction in the length direction. When the outer frame sleeve moves toward the tail sleeve, the connecting protrusion can enter the clearance groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model's MPO connector, when requiring unlocking of the MPO connector and adapter, involves rotating the tail sleeve to allow the connecting protrusion to enter the connecting groove. Pulling the tail sleeve away from the adapter (i.e., away from the first end of the inner frame) causes the tail sleeve, through the connecting protrusion and connecting plate, to move the outer frame away from the adapter. This moves the outer frame relative to the inner frame backward, exposing the snap-fit ​​groove of the inner frame, thus unlocking the adapter and MPO connector. Further pulling the outer frame backward disengages the MPO connector from the adapter. Compared to directly operating the outer frame, the tail sleeve, being further away from the adapter, is easier for the operator to pull, avoiding obstruction of unlocking adjacent MPO connectors. When unlocking the MPO connector and adapter is not needed for an extended period, rotating the tail sleeve allows the connecting protrusion to leave the connecting groove. Pulling the tail sleeve away from the adapter in this case will not unlock the MPO connector and adapter, preventing accidental unlocking by accidentally touching the tail sleeve. In other words, the connection plate and connection protrusion provided in this application facilitate the unlocking of the MPO connector and adapter without increasing the probability of mis-locking between the MPO connector and adapter.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0024] Example 1 like Figures 1-6 As shown, this embodiment provides an MPO connector, including an inner frame sleeve 1, an outer frame sleeve 2, a return spring 3, a tail sleeve 4, and a connecting plate 5. The inner frame sleeve 1 has a first end 15 and a second end 16 disposed opposite each other along a first direction X. The outer wall of the inner frame sleeve 1 is also provided with a snap-fit ​​groove 12 for engaging with a corresponding hook of the corresponding adapter. The outer frame sleeve 2 is sleeved on the middle of the inner frame sleeve 1. The return spring 3 is disposed between the inner frame sleeve 1 and the outer frame sleeve 2, and is used to elastically push the outer frame sleeve 2 towards the first end 15 so that the outer frame sleeve 2 covers the snap-fit ​​groove 12. The tail sleeve 4 is located at the second end 16 of the inner frame sleeve 1. One end of the connecting plate 5 is fixedly connected to the end of the outer frame sleeve 2 near the tail sleeve 4, and the other end extends towards the tail sleeve 4. One of the tail sleeve 4 and the connecting plate 5 is provided with a connecting protrusion 100, and the other is provided with a connecting groove 200. The tail sleeve 4 can rotate relative to the outer frame sleeve 2 so that the connecting protrusion 100 enters and leaves the connecting groove 200. When the connecting protrusion 100 is located in the connecting groove 200 and the tail sleeve 4 moves away from the first end 15 of the inner frame sleeve 1, the connecting protrusion 100 can drive the outer frame sleeve 2 to move away from the first end 15 of the inner frame sleeve 1 through the connecting plate 5.

[0025] The MPO connector provided in this embodiment, when it is necessary to unlock the MPO connector and adapter, involves rotating the tail sleeve 4 to allow the connecting protrusion 100 to enter the connecting groove 200. At this time, by pulling the tail sleeve 4 away from the adapter (i.e., away from the first end 15 of the inner frame sleeve 1), the tail sleeve 4, through the connecting protrusion 100 and the connecting plate 5, can drive the outer frame sleeve 2 to move away from the adapter. This causes the outer frame sleeve 2 to move backward relative to the inner frame sleeve 1, exposing the snap-fit ​​groove 12 of the inner frame sleeve 1, thereby unlocking the adapter and MPO connector. Further pulling the outer frame sleeve 2 backward completes the separation of the MPO connector from the adapter. Compared to directly operating the outer frame sleeve 2, the tail sleeve 4, being farther from the adapter, is easier for the operator to pull, avoiding obstruction of the unlocking operation of adjacent MPO connectors. When the MPO connector and adapter are not needed for an extended period, the tail sleeve 4 can be rotated to disengage the connection protrusion 100 from the connection groove 200. Pulling the tail sleeve 4 away from the adapter will not unlock the MPO connector and adapter, thus preventing accidental unlocking due to accidental contact with the tail sleeve 4. In other words, the connection plate 5 and connection protrusion 100 in this application facilitate unlocking of the MPO connector and adapter without increasing the probability of accidental locking between them.

[0026] like Figure 1 As shown, in this embodiment, the connecting groove 200 is disposed on the connecting plate 5, and the connecting protrusion 100 is disposed on the tail sleeve 4. In other embodiments, the connecting groove 200 may be disposed on the tail sleeve 4, and the connecting protrusion 100 may be disposed on the connecting plate 5.

[0027] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, connecting protrusions 100 are fixedly provided on both sides of the tail sleeve 4. Connecting plates 5 are provided one-to-one with the connecting protrusions 100. Each connecting plate 5 is provided with a connecting groove 200. The openings of the connecting grooves 200 on the two connecting plates 5 face opposite directions. When the tail sleeve 4 rotates relative to the outer frame sleeve 2, the connecting protrusions 100 on both sides of the tail sleeve 4 can respectively enter the connecting grooves 200 on the corresponding connecting plates 5. By providing two connecting protrusions 100 and correspondingly providing two connecting plates 5, the tail sleeve 4 can more stably drive the outer frame sleeve 2 to move away from the adapter.

[0028] Furthermore, such as Figure 1 and Figure 5 As shown, two connecting plates 5 are symmetrically arranged on the end face of the outer frame sleeve 2 near the tail sleeve 4. The arrangement of the connecting plates 5 does not cause an increase in the width of the outer frame sleeve 2.

[0029] Furthermore, such as Figure 1 and Figure 5 As shown, a positioning groove 300 for accommodating the connecting protrusion 100 is provided on the side wall of the connecting groove 200 away from the outer frame sleeve 2. When it is necessary to unlock the MPO connector and the adapter, the connecting protrusion 100 is moved into the connecting groove 200 by rotating the tail sleeve 4. At this time, the tail sleeve 4 is pulled away from the adapter, and the connecting protrusion 100 is partially accommodated in the positioning groove 300, making it difficult for the connecting protrusion 100 to slide along the connecting groove 200, thereby further improving the stability when the tail sleeve 4 drives the outer frame sleeve 2 to move.

[0030] Furthermore, such as Figure 3 As shown, there is a gap between the side wall of the tail sleeve 4 and the connecting plate 5, so that the tail sleeve 4 can rotate relative to the connecting plate 5.

[0031] Furthermore, such as Figure 1 and Figure 6 As shown, the MPO connector also includes a base 400, which is fixedly disposed on the side wall of the tail sleeve 4. The base 400 and the connecting protrusion 100 are respectively disposed in a one-to-one correspondence. The connecting protrusion 100 is fixedly disposed on the corresponding base 400 to avoid the connecting protrusion 100 being too long and thus having too low strength, which would be not conducive to the connecting protrusion 100 pulling the connecting plate 5.

[0032] Furthermore, such as Figure 5 As shown, the length of the connecting plate 5 extends along the first direction X, and the connecting plate 5 is an arc-shaped plate. The degree of curvature of the connecting plate 5 matches the outer wall of the tail sleeve 4.

[0033] Optionally, such as Figures 1-4 As shown, the MPO connector also includes a stopper 6, which includes a stop body 61 and a cantilever 62. The cantilever 62 is connected to the stop body 61 and extends along a first direction X, protruding from the stop body 61. One end of the cantilever 62 extending out of the stop body 61 is connected to the inner frame sleeve 1. The stopper 6 is used to fix the optical fiber passing through the MPO connector and prevent it from loosening or falling out.

[0034] Furthermore, such as Figures 1-4 As shown, the MPO connector also includes a plug-in assembly 7. An inner cavity 11 extending along a first direction X is provided within the inner frame 1. One end of the plug-in assembly 7 is located within the inner cavity 11 of the inner frame 1, and the other end protrudes from the first end 15 of the inner frame 1. An optical fiber passing through the MPO connector is connected to the plug-in assembly 7, and one end of the plug-in assembly 7 extending out of the inner frame 1 mates with the adapter's socket.

[0035] Furthermore, such as Figure 3 and Figure 4As shown, the end of the cantilever 62 furthest from the stop body 61 is provided with a hook 621, and the inner frame sleeve 1 is provided with a corresponding groove 14, into which the hook 621 extends. The hook 621 and the groove 14 cooperate to position the relative position of the cantilever 62 and the inner frame sleeve 1. To facilitate the insertion of the stopper 6 into the inner cavity 11 of the inner frame sleeve 1, the cantilever 62 is elastic, preventing the hook 621 from obstructing the stopper 6 from entering the inner cavity 11 of the inner frame sleeve 1. There are two cantilever arms 62, which are symmetrically connected to the stop body 61. Each cantilever arm 62 is provided with a hook 621, making the connection between the stopper 6 and the inner frame sleeve 1 more stable.

[0036] Furthermore, such as Figure 3 and Figure 4 As shown, the stopper 6 also includes a support sleeve 63, which is fixedly disposed at the end of the stop body 61 away from the cantilever 62. The MPO connector also includes a protective sleeve 9, which is sleeved on the support sleeve 63. The tail sleeve 4 is sleeved on the protective sleeve 9. The tail sleeve 4 can rotate relative to the protective sleeve 9 and can move relative to the protective sleeve 9 along the first direction X.

[0037] Furthermore, such as Figures 1-4 As shown, the MPO connector also includes a main spring 8, one end of which abuts against the plug assembly 7, and the other end abuts against the stop body 61. The main spring 8 elastically pushes the plug assembly 7 to ensure full engagement between the plug assembly 7 and the inside of the adapter socket. At the same time, when the plug assembly 7 is subjected to rigid force during the plugging process, the main spring 8 can buffer the rigid force on the plug assembly 7 to prevent damage to the plug assembly 7.

[0038] Optionally, such as Figure 2 As shown, the outer wall of the first end 15 of the inner frame sleeve 1 is provided with a first hook portion 13, and the inner wall of the outer frame sleeve 2 is provided with a second hook portion 21. When the return spring 3 drives the outer frame sleeve 2 to cover the buckle groove 12, the first hook portion 13 abuts against the second hook portion 21. When the return spring 3 drives the outer frame sleeve 2 to cover the buckle groove 12, the first hook portion 13 abuts against the second hook portion 21 to prevent the outer frame sleeve 2 from coming off the first end 15 of the inner frame sleeve 1.

[0039] Furthermore, such as Figure 2 and Figure 5 As shown, the length of the first hook 13 is along the first direction X. A guide groove 22 is provided on the inner wall of the outer frame sleeve 2. The first hook 13 is partially installed in the guide groove 22, and the second hook 21 is disposed in the guide groove 22. The movement of the outer frame sleeve 2 is guided by the cooperation between the first hook 13 and the guide groove 22.

[0040] In this embodiment, when the MPO connector needs to be removed from the adapter, the tail sleeve 4 is rotated to allow the connecting protrusion 100 to enter the connecting groove 200 on the connecting plate 5. The MPO connector can be unlocked and removed by pulling the tail sleeve 4 away from the adapter.

[0041] When the MPO connector needs to be inserted into the adapter, the connecting protrusion 100 is rotated out of the connecting groove 200 on the connecting plate 5 by rotating the tail sleeve 4. The connecting protrusion 100 is then disengaged from the connecting plate 5. At this time, the connection between the MPO connector and the adapter can be locked by pushing the tail sleeve 4 towards the adapter. During this process, the thrust on the tail sleeve 4 acts on the insertion assembly 7 and the inner frame sleeve 1 through the stop 6 and the main spring 8, connecting the insertion assembly 7 and the inner frame sleeve 1 to the adapter. That is to say, the MPO connector in this embodiment can be inserted and removed by pushing and pulling the tail sleeve 4.

[0042] Example 2 like Figure 7 and Figure 8 As shown, this embodiment provides an MPO connector. The MPO connector in this embodiment is basically the same as the MPO connector in Embodiment 1. The difference is that, in this embodiment, the MPO connector has an avoidance groove 500 on the side wall of the connecting groove 200 near the outer frame sleeve 2 on the connecting plate 5. The avoidance groove 500 is located at the bottom of the connecting groove 200 and connects the two sides of the connecting plate 5 along the first direction X. The length direction of the avoidance groove 500 extends along the first direction X. When the outer frame sleeve 2 moves towards the tail sleeve 4, the connecting protrusion 100 can enter the avoidance groove 500.

[0043] In this embodiment, after the MPO connector is disconnected from the adapter, if it needs to be reconnected, the tail sleeve 4 can be pushed towards the adapter. The pushing force on the tail sleeve 4 acts on the insertion assembly 7 and the inner frame sleeve 1 through the stop 6 and the main spring 8, causing the insertion assembly 7 and the inner frame sleeve 1 to insert into the adapter. During this process, the outer frame sleeve 2 first moves towards the tail sleeve 4 and then returns to its original position. In this embodiment, the MPO connector has a clearance groove 500 on the side wall of the connecting groove 200 near the outer frame sleeve 2. The connecting protrusion 100 can enter the clearance groove 500, so that the presence of the connecting plate 5 does not hinder the movement of the outer frame sleeve 2 towards the tail sleeve 4, making it convenient for operators to perform MPO connector insertion and removal operations.

[0044] Similarly, when the MPO connector and adapter do not need to be unlocked for a long time, the tail sleeve 4 can be rotated so that the connection protrusion 100 on the tail sleeve 4 is away from the connection groove 200 on the connection plate 5. At this time, pulling the tail sleeve 4 away from the adapter will not unlock the MPO connector and adapter, thus avoiding the situation where the MPO connector and adapter are unlocked due to accidental contact with the tail sleeve 4.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
