Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication equipment technology, and in particular to an LC optical fiber connector. Background Technology

[0002] LC fiber optic connectors (Lucent Connectors) are miniaturized, high-density fiber optic connectors widely used in fiber optic communication systems. With the rapid development of big data and the increasing integration of data centers, the use of miniaturized LC fiber optic connectors is becoming more widespread. Therefore, it is necessary to improve the ease of installation and removal of LC fiber optic connectors to meet the requirements for quick connection and unlocking between LC fiber optic connectors and fiber optic adapters.

[0003] Currently, LC fiber optic connectors have a spring at the end used for connecting to the adapter. The connection between the fiber optic connector and the adapter is achieved by the spring abutting against the adapter. To disassemble the fiber optic connector, the spring needs to be pressed down to pull the connector out of the adapter. To facilitate pressing the spring, an operating lever is typically provided on the fiber optic connector. Pressing the spring with the lever unlocks the connection between the connector and the adapter. However, in narrow, densely cabled server rack environments, adding an additional operating lever to the fiber optic connector increases its footprint, making installation inconvenient in such environments.

[0012] When the tail sleeve slides along the first direction, the trigger member moves along the first direction with the tail sleeve, causing the free end of the cantilever member to move downward to press against the pressing part or move upward away from the pressing part.

[0013] In some embodiments, a support sleeve is further included, which is coaxially inserted into the tail sleeve, and the outer wall of the support sleeve is close to the inner wall of the tail sleeve.

[0014] In some embodiments, the device further includes a connector and a guide sleeve, one end of the connector being connected to the first end of the connector body, and the guide sleeve being sleeved on the other end of the connector and coaxially inserted into the tail sleeve.

[0015] In some embodiments, the tail sleeve is provided with one of a positioning block and a positioning hole, and the trigger is provided with the other of the positioning block and the positioning hole. The positioning block is inserted into the positioning hole to connect the tail sleeve and the trigger.

[0016] In some embodiments, the end face of the first end of the connector body is provided with a first guide groove, the depth direction of the first guide groove being parallel to the first direction; the end of the tail sleeve connected to the connector body is provided with a guide block, the guide block being guided and assembled in the first guide groove.

[0017] In some embodiments, the first guide groove has a limiting groove formed in its groove wall, and the length direction of the limiting groove is parallel to the first direction; the guide block is provided with a limiting protrusion, and the limiting protrusion is guided and assembled in the limiting groove.

[0018] In some embodiments, the opening of the first guide groove is disposed toward the tail sleeve, and the limiting groove is provided on both the upper and lower sides of the first guide groove. The limiting protrusion is provided on both the upper and lower sides of the guide block, and the limiting protrusion has a first guide slope inclined toward the tail sleeve.

[0019] In some embodiments, the LC fiber optic connector further has a second direction perpendicular to the first direction;

[0020] The connector body is provided with the first guide groove on both sides in the second direction, and the tail sleeve is provided with the guide block on both sides in the second direction that cooperates with the first guide groove. Each first guide groove is provided with a limiting groove, and each guide block is provided with a limiting protrusion that cooperates with the limiting groove.

[0021] In some embodiments, the LC fiber optic connector further has a second direction perpendicular to the first direction;

[0022] The connector body is provided with a first limiting block and a second limiting block, the first limiting block and the second limiting block are spaced apart along the second direction, and the gap between the first limiting block and the second limiting block forms a slot;

[0023] The first limiting block has a first stop block on the side facing the second limiting block, and the second limiting block has a second stop block on the side facing the first limiting block. The first stop block and the second stop block are respectively located at the slot opening of the slot. Both the first stop block and the second stop block have a second guide slope that is inclined toward the inside of the slot.

[0024] The trigger is provided with a plug-in part, which is inserted into the slot.

[0025] In some embodiments, the free end of the cantilever member is provided with a mounting hole, and a connecting shaft is provided in the mounting hole. The connecting shaft is rotatable relative to the mounting hole. The trigger member is provided with a connecting sleeve, which is sleeved on the outer periphery of the connecting shaft.

[0026] Compared with the prior art, the LC fiber optic connector of this utility model has the following advantages:

[0027] The LC fiber optic connector of this embodiment has a tail sleeve slidably connected to the first end of the connector body. A locking member is provided at a position near the second end of the connector body, and a pressing part is provided at one end of the locking member. A cantilever member is connected to the connector body, and a trigger member is connected to the free end of the cantilever member. The trigger member is connected to the tail sleeve. When the connector is connected to the adapter, the locking member locks the connector body and the adapter. When it is necessary to pull the connector out of the adapter, the tail sleeve is pulled away from the connector body in a first direction. When the tail sleeve slides, it drives the trigger member to slide synchronously, causing the trigger member to pull the free end of the cantilever member downward. When the cantilever member moves downward, it presses against the pressing part, causing the pressing part to move closer to the connector body, unlocking the locking member and the adapter. Continuing to pull the tail sleeve allows the connector to be pulled out of the adapter. Pushing the tail sleeve in the reverse direction causes the trigger element to slide in the opposite direction. The trigger element pushes the free end of the cantilever component upward, moving the cantilever component away from the pressing part. The pressing part loses the pressure from the cantilever component and, under its own elastic potential energy, moves away from the connector body to reset. Continuing to push the tail sleeve allows the connector body to be inserted into the adapter, and the locking element locks the connector to the adapter. This invention connects the trigger element to the tail sleeve, allowing the connector to be unlocked or locked by pushing or pulling the tail sleeve. It eliminates the need for an additional operating lever to apply pressure to the pressing part, reducing the connector's thickness and overall space occupation, making it convenient for placement in narrow spaces and densely wired environments.

[0038] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of 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.

[0040] 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.

[0041] See Figures 1-4As shown, this utility model embodiment provides an LC fiber optic connector with a first direction X, which is the length direction of the LC fiber optic connector. The LC fiber optic connector includes a connector body 10, a tail sleeve 20, a locking member 30, a cantilever member 40, and a trigger member 50. The connector body 10 has a first end 101 and a second end 102, which are arranged along the first direction X. The second end 102 of the connector body 10 is used to insert into an adapter and connect to the adapter. The tail sleeve 20 is slidably connected to the first end 101, and the sliding direction of the tail sleeve 20 is parallel to the first direction X. One end of the locking member 30 is connected to the connector body 10 and close to the second end 102 of the connector body 10. The other end of the locking member 30 is provided with a pressing part 31, which is spaced apart from the connector body 10. The locking member 30 is configured to lock the connector body 10 to the adapter; the cantilever member 40 has a fixed end 401 and a free end 402, the fixed end 401 is connected to the connector body 10, and the free end 402 is located on the upper side of the pressing part 31; the trigger member 50 is guided and assembled on the connector body 10 along the first direction X, one end of the trigger member 50 is connected to the tail sleeve 20, and the other end of the trigger member 50 is connected to the free end 402 of the cantilever member 40; when the tail sleeve 20 slides along the first direction X, the trigger member 50 moves with the tail sleeve 20 along the first direction X, causing the free end 402 of the cantilever member 40 to move downward to press against the pressing part 31 or move upward away from the pressing part 31.

[0042] It should be noted that both the locking member 30 and the cantilever member 40 are elastic members, which are elastic so that the pressing part 31 of the locking member 30 can automatically rebound and reset under its own elastic action when the pressing action of the cantilever member 40 is lost; when the trigger member 50 pushes the free end 402, the elastic potential energy of the cantilever member 40 helps the free end 402 to move upward and reset.

[0043] When it is necessary to remove the connector from the adapter, pull the tail sleeve 20 away from the connector body 10 in the first direction X. When the tail sleeve 20 slides, it drives the trigger 50 to slide synchronously, causing the trigger 50 to pull the free end 402 of the cantilever member 40 downward. When the cantilever member 40 moves downward, it presses against the pressing part 31, causing the pressing part 31 to move closer to the connector body 10, unlocking the locking member 30 and the adapter. Continue pulling the tail sleeve 20 to allow the connector to be removed from the adapter. Push the tail sleeve 20 in the opposite direction, causing the tail sleeve 20 to drive the trigger 50 to slide in the opposite direction. The trigger 50 pushes the free end 402 of the cantilever member 40 upward, causing the cantilever member 40 to move away from the pressing part 31. The pressing part 31 loses the pressing force of the cantilever member 40 and moves away from the connector body 10 to reset under the action of its own elastic potential energy. Continue pushing the tail sleeve 20 to insert the connector body 10 into the adapter, and lock the connector and adapter by the locking member 30. This utility model connects the trigger 50 to the tail sleeve 20, and the connector can be unlocked or locked by pushing or pulling the tail sleeve 20. It is easy to operate and does not require an additional operating rod to apply pressure to the pressing part 31. This reduces the thickness of the connector, reduces the overall space occupied by the connector, improves the integration of the connector, and makes it convenient to place the connector in environments with narrow space and dense wiring.

[0044] See Figure 1 and Figure 2 As shown, in some embodiments, the tail sleeve 20 is provided with one of a positioning block 21 and a positioning hole 51, and the trigger member 50 is provided with the other of a positioning block 21 and a positioning hole 51. The positioning block 21 is inserted into the positioning hole 51 to connect the tail sleeve 20 and the trigger member 50. The connection between the tail sleeve 20 and the trigger member 50 is achieved by the cooperation of the positioning block 21 and the positioning hole 51, ensuring that the trigger member 50 can move synchronously with the tail sleeve 20 when the tail sleeve 20 is pushed or pulled, and facilitating the installation and removal of the trigger member 50 on the tail sleeve 20. In this embodiment, the tail sleeve 20 is provided with a positioning block 21, and the trigger member 50 is provided with a positioning hole 51. It should be noted that the shape of the positioning block 21 matches the shape of the positioning hole 51.

[0045] See Figure 2 and Figure 5 As shown, in some embodiments, the LC fiber optic connector further includes a support sleeve 60, which is coaxially inserted into the tail sleeve 20, with the outer wall of the support sleeve 60 close to the inner wall of the tail sleeve 20. The length direction of the support sleeve 60 is parallel to the first direction X. The support sleeve 60 increases the lateral tensile strength of the tail sleeve 20. A limiting step is provided on the inner wall of the end of the tail sleeve 20 that connects to the connector body 10. The support sleeve 60 abuts against the limiting step within the tail sleeve 20, preventing the support sleeve 60 from axially protruding within the tail sleeve 20.

[0046] See Figure 2 and Figure 7 As shown, in some embodiments, the LC fiber optic connector further includes a connector 70 and a guide sleeve 80. One end of the connector 70 is connected to the first end 101 of the connector body 10, and the guide sleeve 80 is sleeved on the other end of the connector 70 and coaxially inserted into the tail sleeve 20. When the tail sleeve 20 is pushed or pulled, the tail sleeve 20 slides along the outer wall of the guide sleeve 80. The guide sleeve 80 guides the sliding of the tail sleeve 20 and limits the sliding direction of the tail sleeve 20. The connector 70 is detachably connected to the connector body 10. Optionally, in some embodiments, the first end 101 of the connector body 10 is provided with a slot, and the end of the connector 70 is provided with a flange. The flange is engaged in the slot, and the connection between the connector 70 and the connector body 10 is achieved through the cooperation of the flange and the slot, which facilitates disassembly and assembly.

[0047] See Figure 5 and Figure 6 As shown, in some embodiments, the end face of the first end 101 of the connector body 10 is provided with a first guide groove 103, the groove depth direction of the first guide groove 103 being parallel to the first direction X; the end of the tail sleeve 20 connected to the connector body 10 is provided with a guide block 22, which is guided and fitted into the first guide groove 103. By setting the guide block 22 and the first guide groove 103, not only can the sliding of the tail sleeve 20 be guided, but also, the guide block 22 extends along the first direction X and protrudes from the tail sleeve 20 at the end of the tail sleeve 20 connected to the connector body 10. Inserting the guide block 22 into the first guide groove 103 can also increase the bending resistance of the tail sleeve 20. To facilitate the insertion of the guide block 22, the opening of the first guide groove 103 is oriented towards the tail sleeve 20.

[0048] See Figure 5 and Figure 6 As shown, in some embodiments, the first guide groove 103 has a limiting groove 104 formed in its groove wall, and the length direction of the limiting groove 104 is parallel to the first direction X. The guide block 22 is provided with a limiting protrusion 23, which is guided and assembled in the limiting groove 104. When the tail sleeve 20 is pushed or pulled, the guide block 22 slides in the first guide groove 103, and the limiting protrusion 23 slides in the limiting groove 104. The limiting groove 104 can limit the movement stroke of the limiting protrusion 23, thereby limiting the sliding stroke of the tail sleeve 20 and preventing the tail sleeve 20 from disengaging from the connector body 10. Therefore, this setting can not only guide the sliding of the tail sleeve 20, but also limit the sliding stroke of the tail sleeve 20, so that the tail sleeve 20 and the connector body 10 are always connected. After the tail sleeve 20 reaches the limit of the stroke of the limiting protrusion 23 in the limiting groove 104, continuing to push or pull the tail sleeve 20 can make the tail sleeve 20 and the connector body 10 move synchronously.

[0049] See Figure 5 and Figure 6 As shown, in some embodiments, the opening of the first guide groove 103 faces the tail sleeve 20. Limiting grooves 104 are provided on both the upper and lower sides of the first guide groove 103, and limiting protrusions 23 are provided on both the upper and lower sides of the guide block 22. The limiting protrusions 23 have a first guide slope 231 inclined towards the tail sleeve 20. The first guide slope 231 facilitates the insertion of the guide block 22 into the first guide groove 103, preventing the limiting protrusions 23 from blocking the insertion of the guide block 22. The limiting grooves 104 are located on the upper and lower sides of the first guide groove 103, allowing the limiting grooves 104 to penetrate the connector body 10 vertically, facilitating the fabrication of the limiting grooves 104. In other embodiments, the limiting grooves 104 can also be located on both sides of the first guide groove 103 along the second direction Y. Correspondingly, the limiting protrusions 23 are located on both sides of the guide block 22 along the second direction Y. The second direction Y is perpendicular to the first direction X, and the second direction Y is the width direction of the connector.

[0050] See Figure 5 and Figure 6 As shown, in some embodiments, the connector body 10 has first guide grooves 103 on both sides in the second direction Y, and the tail sleeve 20 has guide blocks 22 on both sides in the second direction Y that cooperate with the first guide grooves 103. Each first guide groove 103 has a limiting groove 104, and each guide block 22 has a limiting protrusion 23 that cooperates with the limiting groove 104. This arrangement can enhance the bending resistance of the tail sleeve 20 on both sides in the second direction Y. It should be noted that each first guide groove 103 has a corresponding guide block 22, and each guide block 22 has a limiting protrusion 23 corresponding to the limiting groove 104.

[0051] See Figure 6As shown, in some embodiments, the connector body 10 is provided with a first limiting block 105 and a second limiting block 106. The first limiting block 105 and the second limiting block 106 are spaced apart along the second direction Y, and the gap between the first limiting block 105 and the second limiting block 106 forms a slot 107. The side of the first limiting block 105 facing the second limiting block 106 is provided with a first stop block 1051, and the side of the second limiting block 106 facing the first limiting block 105 is provided with a second stop block 1061. The first stop block 1051 and the second stop block 1061 are respectively located at the slot opening of the slot 107. The first stop block 1051 and the second stop block 1061 are both provided with a second guide slope 10511 that is inclined towards the inside of the slot 107. The trigger member 50 is provided with a plug-in part 52, which is inserted into the slot 107. The trigger member 50 passes through the slot 107 and is connected to the tail sleeve 20. When the trigger 50 slides along the tail sleeve 20 in the first direction X, the insertion part 52 slides along the slot 107. The slot 107 not only guides the sliding of the trigger 50, preventing it from shifting in the second direction Y, but also, through the cooperation of the slot 107 with the first stop block 1051 and the second stop block 1061, limits the insertion part 52 of the trigger 50 within the slot 107, preventing it from coming out of the slot 107. The second guide slope 10511 facilitates pressing the insertion part 52 into the slot 107.

[0052] See Figure 6 As shown, in some embodiments, a second guide groove 108 is provided on the upper side of the connector body 10. The length direction of the second guide groove 108 extends along the first direction X, and the opening of the second guide groove 108 faces upward. The trigger member 50 is partially embedded in the second guide groove 108, and the sliding path of the trigger member 50 is limited by the second guide groove 108.

[0053] See Figure 4As shown, in some embodiments, the free end 402 of the cantilever member 40 has a mounting hole 4021, and a connecting shaft 41 is provided in the mounting hole 4021. The connecting shaft 41 is rotatable relative to the mounting hole 4021. The trigger member 50 has a connecting sleeve 53, which is sleeved on the outer periphery of the connecting shaft 41. The central axis direction of the mounting hole 4021 and the axial direction of the connecting shaft 41 are respectively parallel to the second direction Y, wherein the central axis direction of the mounting hole 4021 refers to its central axis extending in the axial direction. When the trigger member 50 slides with the tail sleeve 20, the trigger member 50 drives the free end 402 of the cantilever member 40 to move downward or upward through the connecting sleeve 53 and the connecting shaft 41. One end of the connecting sleeve 53 of the trigger member 50 is arc-shaped to reserve space for the downward movement of the connecting sleeve 53. The cantilever component 40 has a bending portion 42 near the fixed end 401. The bending portion 42 is U-shaped, which gives the cantilever component 40 good elastic deformation ability and facilitates the downward movement of the free end 402 of the cantilever component 40.

[0054] See Figure 2 As shown, in some embodiments, the connector body 10 includes a first housing 11, a second housing 12, a ferrule 13, and a third housing 14. The second housing 12 is connected to the first housing 11, and at least partially extends into the first housing 11. The ferrule 13 is inserted into the first housing 11 and the second housing 12, and extends out of the first housing 11. One end of the ferrule 13 extending out of the first housing 11 forms a second end 102. The third housing 14 is connected between the second housing 12 and the tail sleeve 20. One end of the third housing 14 connected to the tail sleeve 20 forms a first end 101. A locking member 30 is connected to the first housing 11, and a cantilever member 40 is connected to the third housing 14. Setting the connector body 10 as a multi-part connection facilitates the manufacturing and assembly of the connector body 10. The first limiting block 105 and the second limiting block 106 are both fixed to the third housing 14. The first guide groove 103 and the second guide groove 108 are both formed on the third housing 14.

[0055] In some embodiments, the LC fiber optic connector is a dual-core fiber optic connector, with two first housings 11, two second housings 12, and two ferrules 13. Two fiber optic channels are formed within the third housing 14, each corresponding to one of the first housings 11, one of the second housings 12, and one of the ferrules 13. Each first housing 11 is provided with a locking element 30, and each locking element 30 is correspondingly provided with a cantilever member 40. The two cantilever members 40 are connected together to ensure simultaneous unlocking of the two locking elements 30.

[0056] It should be noted that, in order to facilitate the rapid reset of the locking member 30 and the cantilever member 40, both the locking member 30 and the cantilever member 40 are elastic.

[0057] The working process of this utility model is as follows:

[0058] Pull the tail sleeve 20 away from the connector body 10 in the first direction X. When the tail sleeve 20 slides, it drives the trigger 50 to slide synchronously. The trigger 50 pulls the connecting shaft 41 through the connecting sleeve 53 it provides. The connecting shaft 41 drives the free end 402 of the cantilever member 40 to move downward, so that the free end 402 of the cantilever member 40 gradually presses against the pressing part 31, so that the pressing part 31 moves closer to the connector body 10, unlocking the connection between the locking member 30 and the adapter. Thus, when the tail sleeve 20 is pulled further, the connector can be pulled out from the adapter.

[0059] Pushing the tail sleeve 20 towards the connector body 10 causes the trigger 50 to slide synchronously, pushing the free end 402 of the cantilever member 40 upward to reset it, thus moving the free end 402 of the cantilever member 40 away from the pressing part 31. The pressing part 31, losing the pressure of the cantilever member 40, moves away from the connector body 10 under its own elastic potential energy, resetting itself and continuing to push the tail sleeve 20. The connector body 10 moves synchronously with the tail sleeve 20, inserting into the adapter. After the connector body 10 is pushed into place, the locking member 30 locks the connector body 10 and the adapter, thereby connecting the connector and the adapter.

[0060] In summary, this utility model embodiment provides an LC fiber optic connector that connects the trigger element 50 to the tail sleeve 20. The connector can be unlocked or locked by pushing or pulling the tail sleeve 20, eliminating the need for an additional operating lever to apply pressure to the pressing part 31. This reduces the connector's thickness and overall space requirements, making it convenient for placement in environments with limited space and dense wiring. The support sleeve 60 inside the tail sleeve 20 increases its lateral tensile strength. A guide block 22 extends along the first direction X at the end of the tail sleeve 20 connected to the connector body 10. Inserting the guide block 22 into the first guide groove 103 enhances the tail sleeve 20's bending resistance.

[0061] 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.
