Description

Technical Field

[0001] This application relates to the field of fiber optic connector technology, and for example to a push-pull structure for fiber optic connectors and fiber optic connectors. Background Technology

[0002] Currently, with the rapid popularization of 5G, artificial intelligence, IoT, and big data technologies, the bandwidth demand of hyperscale data centers and cloud service providers for fiber optic communication systems continues to increase, making high-density fiber optic connections one of the core requirements for industry development. Fiber optic connectors, as key components of fiber optic connection systems, are widely used in fiber optic deployment scenarios within limited spaces due to their suitability for high-density splicing. Currently, to meet the demand for even higher density connections, the arrangement density of fiber optic connectors on patch panels is constantly increasing, leading to a significant reduction in the operating clearance between adjacent connectors. This results in a severe lack of operating space for inserting and removing fiber optic connectors on high-density patch panels. Conventional manual insertion and removal methods easily compress adjacent connectors, thus affecting the normal use of other fiber optic plugs.

[0003] To address the issue of insufficient operating space in high-density scenarios, various improvement solutions have been proposed. For example, optimizing the overall structural dimensions of the connector can further reduce the volume of a single connector, decreasing the space it occupies in the patch panel and thus allowing more clearance for the insertion and removal of adjacent connectors. Alternatively, the locking and unlocking structure of the connector can be moved from the traditional front position to the side or top, designing a side-pressing or top-toggle locking mechanism. This allows operators to perform insertion and removal by contacting the side or top operating parts even in space-constrained situations, thus adapting to the usage requirements of high-density array scenarios.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: Neither reducing the connector size nor adopting a side / top-triggered locking mechanism can achieve tool-free plugging and unplugging. Reducing the size to allow for more operating space requires specialized tools to precisely apply to the locking structure for unlocking, increasing both the number of steps and operating costs. While relocating the locking mechanism eliminates the need for tools, the release process requires significant force or multiple steps. In the confined space of high-density patch panels, operators still struggle to quickly and smoothly complete plugging and unplugging operations, severely hindering the maintenance efficiency of fiber optic connection systems.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a push-pull structure for fiber optic connectors and a fiber optic connector to enable convenient insertion and removal without tools, thereby improving the maintenance efficiency of fiber optic connection systems.

[0008] In some embodiments, the push-pull structure for the fiber optic connector includes: a tail sleeve configured to move along a preset direction; a cantilever lever mechanically coupled to the tail sleeve and including a locking structure; wherein the movement of the tail sleeve along the preset direction can be converted into rotation of the cantilever lever, thereby driving the locking structure to move.

[0009] Optionally, the tail sleeve includes: a protruding structure having a first sliding surface intersecting a preset direction; wherein, when the tail sleeve moves along the preset direction, at least a portion of the cantilever lever structure can slide along the first sliding surface, causing the cantilever lever to rotate.

[0010] Optionally, when the tail sleeve moves in a preset direction, at least a portion of the cantilever lever structure can slide along the first sliding surface, causing the cantilever lever to rotate.

[0011] Optionally, the cantilever lever includes: a second sliding surface intersecting a preset direction; wherein, when the tail sleeve moves along the preset direction, at least a portion of the tail sleeve structure can slide along the second sliding surface, causing the cantilever lever to rotate.

[0012] Optionally, when the cantilever lever rotates, the action of the locking structure has at least a component in the opposite direction to the movement of the tail sleeve.

[0013] Optionally, the locking structure is located at the end of the cantilever lever away from the tail sleeve; wherein, when the tail sleeve moves in a preset direction along the side away from the cantilever lever, the end of the cantilever lever away from the tail sleeve rotates toward the axis of the fiber optic connector, and the locking structure can be released from the adapter; when the tail sleeve moves in a preset direction along the side of the cantilever lever, the end of the cantilever lever away from the tail sleeve rotates toward the axis of the fiber optic connector, and the locking structure can be locked with the adapter.

[0014] Optionally, the cantilever lever has an elastic restoring force. When the tail sleeve is pulled, the cantilever lever overcomes the elastic restoring force and rotates away from the initial position. When the tail sleeve is released, the elastic restoring force drives the cantilever lever to rotate back to the initial position. Among these, when the cantilever lever is in the initial position, the locking structure is furthest from the axis of the fiber optic connector.

[0015] Optionally, the push-pull structure for the fiber optic connector further includes: a connecting body, wherein the rotation fulcrum of the cantilever lever is located on the surface of the connecting body, and a tail sleeve is fitted onto the connecting body.

[0016] Optionally, the connecting body includes: a displacement guide groove, with at least a portion of the tail sleeve structure located within the displacement guide groove, so that the tail sleeve can only move in a preset direction.

[0017] Optionally, the tail sleeve is provided with at least one opening slot on the side away from the cantilever lever, so that the tail sleeve has elasticity along the axial direction of the fiber optic connector.

[0018] In some embodiments, the fiber optic connector includes: the push-pull structure for the fiber optic connector described above. The push-pull structure and fiber optic connector for fiber optic connectors provided in this disclosure can achieve the following technical effects: The tail sleeve's design, allowing it to move in a preset direction, enables users to manually operate it without the need for specialized tools, facilitating connector insertion and removal. The tail sleeve is mechanically coupled to a cantilever lever; as the tail sleeve moves, its motion is mechanically converted into the rotation of the cantilever lever, driving the locking mechanism. This lever principle transforms the linear movement of the tail sleeve into radial or reverse displacement of the locking mechanism, allowing it to lock or release the adapter with minimal effort. This reduces the difficulty of insertion and removal caused by limited space in high-density patch panels. The rotation of the cantilever lever controls the locking mechanism's movement, preventing interference from squeezing adjacent connectors during insertion and removal, thus improving the maintenance efficiency and ease of operation of the fiber optic connection system.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0030] Combination Figure 1-7 As shown, this embodiment of the present disclosure provides a push-pull structure for an optical fiber connector 1, including a tail sleeve 4 and an arm lever. The tail sleeve 4 is configured to move along a preset direction; the cantilever lever 5 is mechanically coupled to the tail sleeve 4 and includes a locking structure 6; wherein, the movement of the tail sleeve 4 along the preset direction can be converted into the rotation of the cantilever lever 5, thereby driving the locking structure 6 to operate.

[0031] In this embodiment of the application, the preset direction includes the axial direction of the fiber optic connector 1.

[0032] In this embodiment, the tail sleeve 4 is a component of the fiber optic connector 1, configured to be manually operated by a user to move in a preset direction, thereby driving the cantilever lever 5 to rotate. The tail sleeve 4 may include a gripping part for easy operation and may have various structural forms, such as a cylindrical shell, a polygonal shell, or a sleeve with anti-slip texture, to adapt to the design requirements of different fiber optic connectors 1. The direction of movement of the tail sleeve 4 is usually consistent with the axis of the fiber optic connector 1, but it can also be in other directions, as long as the movement of the tail sleeve 4 can be converted into the rotation of the cantilever lever 5 through mechanical coupling.

[0033] In this embodiment, the preset direction refers to the direction in which the tail sleeve 4 is restricted to move. This direction is typically parallel to the axis of the fiber optic connector 1, but can also include directions at acute or obtuse angles to the axis, as long as the movement of the tail sleeve 4 can be effectively converted into the rotation of the cantilever lever 5. The preset direction can be a straight line or an arc, but a straight line is preferred to simplify operation and structural design. For example, the preset direction can be an axial movement direction defined by the displacement guide groove 34 or an oblique movement direction guided by the guide rail.

[0034] In this embodiment, the cantilever lever 5 is a lever element in the fiber optic connector 1, mechanically coupled to the tail sleeve 4 and including a locking structure 6. The cantilever lever 5 can have various shapes and structures, such as a U-shaped lever, an L-shaped lever, or a straight-arm lever, as long as it can rotate about the pivot point 33 and convert the movement of the tail sleeve 4 into the action of the locking structure 6. The cantilever lever 5 is typically made of an elastic material to provide elastic restoring force, but it can also be made of a rigid material and rely on an external spring to provide restoring force.

[0035] In this embodiment, mechanical coupling refers to the physical connection or interaction between the tail sleeve 4 and the cantilever lever 5, enabling the movement of the tail sleeve 4 to be transmitted to the cantilever lever 5 and drive its rotation. Mechanical coupling can be achieved through direct contact, inclined surface engagement, protrusion and groove fitting, or other mechanical connection methods. For example, mechanical coupling may include the protrusion structure 41 of the tail sleeve 4 contacting the sliding surface of the cantilever lever 5, or the hook-shaped portion of the cantilever lever 5 engaging with the groove of the tail sleeve 4.

[0036] In this embodiment, the locking structure 6 is part of the cantilever lever 5 and is used to lock or release the adapter 2. The locking structure 6 may include various locking elements, such as buckles 63, hooks, protrusions, or claws, to engage or disengage with corresponding structures within the adapter 2. For example, the locking structure 6 may be a double buckle 63 structure for symmetrical engagement, or a single buckle 63 structure for unidirectional locking, ensuring a reliable connection between the fiber optic connector 1 and the adapter 2.

[0037] In this embodiment, the conversion of the movement of the tail sleeve 4 along a preset direction into the rotation of the cantilever lever 5 is achieved through mechanical action, wherein the linear movement of the tail sleeve 4 is guided into the rotational motion of the cantilever lever 5 about the pivot point 33. This conversion can be achieved through inclined plane sliding, lever principle, or cam mechanism. For example, the conversion may include the sliding surface of the tail sleeve 4 relative to the sliding surface of the cantilever lever 5, or the movement of the tail sleeve 4 being transmitted to the cantilever lever 5 via a connecting rod.

[0038] In this embodiment, driving the locking structure 6 to move means that the rotation of the cantilever lever 5 causes the locking structure 6 to shift or change its state, thereby locking or releasing it from the adapter 2. The movement of the locking structure 6 may include radial movement, axial movement, or angular change. For example, driving the locking structure 6 to move it toward the axis of the fiber optic connector 1 to release the adapter 2, or to move it away from the axis to lock the adapter 2.

[0039] The push-pull structure for the fiber optic connector 1 provided in this embodiment allows the tail sleeve 4 to move along a preset direction, enabling users to manually operate the tail sleeve 4 directly without the need for special tools to insert or remove the connector. The tail sleeve 4 is mechanically coupled to the cantilever lever 5. When the tail sleeve 4 moves, its motion is mechanically converted into the rotation of the cantilever lever 5, thereby driving the locking structure 6 to move. Through the lever principle, the linear movement of the tail sleeve 4 is converted into the radial or reverse displacement of the locking structure 6, allowing the locking structure 6 to lock or release with the adapter 2 with minimal operating force. This reduces the difficulty of insertion and removal caused by limited operating space in high-density patch panels. The rotation of the cantilever lever 5 controls the movement of the locking structure 6, preventing squeezing interference with adjacent connectors during insertion and removal, thus improving the maintenance efficiency and ease of operation of the fiber optic connection system.

[0040] Optionally, the tail sleeve 4 includes a protruding structure 41. The protruding structure 41 has a first sliding surface 42 intersecting a preset direction; wherein, when the tail sleeve 4 moves along the preset direction, at least a portion of the cantilever lever 5 can slide along the first sliding surface 42, causing the cantilever lever 5 to rotate.

[0041] In this embodiment, the protrusion structure 41 is a component of the tail sleeve 4, used for mechanical interaction with the cantilever lever 5 to transmit motion and force. The protrusion structure 41 can have various geometries, such as block protrusions, rib protrusions, or platform protrusions, to provide a stable contact interface with the cantilever lever 5. The protrusion structure 41 can be located on the inner wall, outer wall, or end of the tail sleeve 4, and can include one or more protrusion units to enhance the reliability and balance of the interaction. For example, the protrusion structure 41 can be a radially projecting block on the inner side of the tail sleeve 4, or an axially extending platform at the end of the tail sleeve 4.

[0042] In this embodiment, the first sliding surface 42 is a functional surface on the protruding structure 41, configured to slide in contact with at least a portion of the cantilever lever 5. The first sliding surface 42 intersects a preset direction, such that the movement of the tail sleeve 4 along the preset direction can drive the cantilever lever 5 to rotate through sliding interaction. The first sliding surface 42 can have different surface morphologies, such as a flat inclined surface, a curved inclined surface, or a stepped inclined surface, as long as it can guide the structure of the cantilever lever 5 to slide smoothly. For example, the first sliding surface 42 can be an inclined plane at an acute angle to the preset direction, or an arcuate surface at an obtuse angle to the preset direction.

[0043] In this embodiment, the sliding of at least a portion of the cantilever lever 5 along the first sliding surface 42 means that a specific area of ​​the cantilever lever 5 maintains physical contact with the first sliding surface 42 and undergoes relative displacement. This portion of the cantilever lever 5 can be the end region, root region, or middle region of the cantilever lever 5, and can have suitable contact features such as sliding surfaces or contact points. For example, the root of the cantilever lever 5 can have a second sliding surface 51 that slides in conjunction with the first sliding surface 42, or the hook-shaped end of the cantilever lever 5 can move along the first sliding surface 42.

[0044] In this embodiment, rotating the cantilever lever 5 means that the cantilever lever 5 rotates around its pivot point 33 through the movement of the tail sleeve 4 and the sliding contact between the first sliding surface 42 and the cantilever lever 5. Rotation can include rotation in a second direction or rotation in a first direction, depending on the relative arrangement of the protruding structure 41 and the cantilever lever 5 and the direction of force. Rotation causes the locking structure 6 on the cantilever lever 5 to displace or change its state, thereby achieving a locking or releasing function with the adapter 2. For example, rotation of the cantilever lever 5 can cause the locking structure 6 to move towards the axis of the fiber optic connector 1 to release the adapter 2, or to move away from the axis to lock the adapter 2.

[0045] Thus, the tail sleeve 4 is configured to move along a preset direction (the axial direction of the fiber optic connector 1). Its protruding structure 41 has a first sliding surface 42 intersecting the preset direction. When the tail sleeve 4 moves along the preset direction, at least a portion of the cantilever lever 5, mechanically coupled to the tail sleeve 4, slides along the first sliding surface 42. Because the first sliding surface 42 intersects the preset direction, the linear movement of the tail sleeve 4 is converted into a force that causes the cantilever lever 5 to rotate around its pivot point 33 through the sliding engagement of the first sliding surface 42 and the cantilever lever 5. This allows the user to drive the cantilever lever 5 to rotate simply by manually pushing and pulling the tail sleeve 4, without the need for special tools, thereby actuating the locking structure 6 on the cantilever lever 5. This method avoids the inconvenience of using tools to plug and unplug connectors in high-density patch panels due to limited operating space, reducing operational difficulty and cost. Furthermore, the structural design of the first sliding surface 42 optimizes force transmission efficiency, reducing the operating force required to drive the cantilever lever 5 to rotate, thereby reducing the possibility of squeezing interference to adjacent connectors during plugging and unplugging.

[0046] Optionally, when the tail sleeve 4 moves in a preset direction, at least a portion of the structure of the cantilever lever 5 can slide along the first sliding surface 42, causing the cantilever lever 5 to rotate.

[0047] In this embodiment, the ability of at least a portion of the cantilever lever 5 to slide along the first sliding surface 42 means that a specific area of ​​the cantilever lever 5 remains in contact with the first sliding surface 42 on the protruding structure 41 of the tail sleeve 4 and undergoes relative displacement. This portion of the cantilever lever 5 can be the end, root, or middle part of the cantilever lever 5, and can have suitable contact features to achieve smooth sliding. For example, this portion of the cantilever lever 5 can be the second sliding surface 51 provided at the root of the cantilever lever 5, or a contact protrusion protruding from the middle of the cantilever lever 5.

[0048] In this embodiment, sliding along the first sliding surface 42 means that at least a portion of the structure of the cantilever lever 5 is guided to move on the surface of the first sliding surface 42. This sliding can be linear sliding, curved sliding, or a combination thereof, and may be accompanied by friction or rolling. For example, sliding may include the sliding surface of the cantilever lever 5 moving along an inclined plane of the first sliding surface 42, or the rollers of the cantilever lever 5 rolling along an arcuate groove of the first sliding surface 42.

[0049] In this embodiment, rotating the cantilever lever 5 means that the interaction of at least a portion of the cantilever lever 5 sliding along the first sliding surface 42 causes the cantilever lever 5 to rotate about its pivot point 33. Rotation can include angular displacement of the cantilever lever 5, either entirely or partially, about a fixed axis or a virtual pivot point. For example, rotation can include clockwise or in a first direction rotation of the cantilever lever 5 about the pivot point 33 connecting to the surface of the body 3, or a similar rotational effect produced by the elastic bending deformation of the cantilever lever 5.

[0050] In this way, since the first sliding surface 42 intersects with the preset direction, a guiding effect is generated during the sliding process, which converts the linear movement of the tail sleeve 4 into the rotation of the cantilever lever 5, so that the locking structure 6 can achieve radial or reverse displacement with a small operating force.

[0051] Optionally, the cantilever lever 5 includes a second sliding surface 51. The second sliding surface 51 intersects a preset direction; wherein, when the tail sleeve 4 moves along the preset direction, at least a portion of the structure of the tail sleeve 4 can slide along the second sliding surface 51, causing the cantilever lever 5 to rotate.

[0052] In this embodiment, the second sliding surface 51 is a functional surface on the cantilever lever 5, configured to slide in contact with at least a portion of the structure of the tail sleeve 4. The second sliding surface 51 intersects a preset direction, such that the movement of the tail sleeve 4 along the preset direction can drive the cantilever lever 5 to rotate through sliding interaction. The second sliding surface 51 can have different surface morphologies, such as a flat inclined surface, a curved inclined surface, or a stepped inclined surface, as long as it can guide the structure of the tail sleeve 4 to slide smoothly. For example, the second sliding surface 51 can be an inclined plane at an acute angle to the preset direction, or an arcuate surface at an obtuse angle to the preset direction.

[0053] In this embodiment, the ability of at least a portion of the tail sleeve 4 to slide along the second sliding surface 51 means that a specific area of ​​the tail sleeve 4 maintains physical contact with the second sliding surface 51 on the cantilever lever 5 and undergoes relative displacement. This portion of the tail sleeve 4 may be a protruding structure 41, an end region, or an inner wall region, and may have suitable contact features to achieve smooth sliding. For example, the first sliding surface 42 of the protruding structure 41 of the tail sleeve 4 may slide in conjunction with the second sliding surface 51, or the guide protrusion of the tail sleeve 4 may move along the second sliding surface 51.

[0054] In this embodiment, when the tail sleeve 4 moves along a preset direction, at least a portion of the tail sleeve 4 slides along the second sliding surface 51, causing the cantilever lever 5 to rotate. This means that through the movement of the tail sleeve 4 and the sliding contact between the second sliding surface 51 and the tail sleeve 4 structure, the cantilever lever 5 rotates around its pivot point 33. The rotation can include rotation in a second direction or rotation in a first direction, depending on the relative arrangement of the second sliding surface 51 and the tail sleeve 4 structure and the direction of force. For example, when the protruding structure 41 of the tail sleeve 4 slides along the second sliding surface 51 in a preset direction, it can push the cantilever lever 5 to rotate around the pivot point 33, thereby causing the locking structure 6 to displace.

[0055] In this embodiment, the angle between the first sliding surface 42 or the second sliding surface 51 and the axial direction of the fiber optic connector 1 is an acute angle. Both the first sliding surface 42 and the second sliding surface 51 are set to form an acute angle with the axial direction of the fiber optic connector 1. When the tail sleeve 4 moves axially, this tilt angle causes the first sliding surface 42 of the protruding structure 41 of the tail sleeve 4 to generate a diagonal thrust with both axial and radial components on the second sliding surface 51 of the cantilever lever 5. Due to the acute angle, the radial component is sufficient to overcome the elastic restoring force of the cantilever lever 5 and push the cantilever lever 5 to rotate around the pivot point 33, thereby converting the small linear stroke of the tail sleeve 4 into the radial retraction of the locking structure 6, achieving easy unlocking. Conversely, when the tail sleeve 4 is pushed back in the opposite direction, the same inclined surface action causes the locking structure 6 to extend and engage with the adapter 2.

[0056] Thus, by providing a second sliding surface 51 intersecting the preset direction on the cantilever lever 5, at least a portion of the tail sleeve 4 can slide along the second sliding surface 51 when it moves in the preset direction. This sliding contact converts the linear motion of the tail sleeve 4 into a rotational force on the cantilever lever 5, thereby driving the cantilever lever 5 to rotate around its fulcrum. The guiding effect of the sliding surface achieves the conversion of motion, allowing the user to effectively control the movement of the cantilever lever 5 and the locking structure 6 with simple linear operation of the tail sleeve 4.

[0057] Optionally, when the cantilever lever 5 rotates, the action of the locking structure 6 has at least a component in the opposite direction to the movement direction of the tail sleeve 4.

[0058] In this embodiment, the action of the locking structure 6 having at least a component opposite to the direction of movement of the tail sleeve 4 means that the motion trajectory generated by the locking structure 6 when the cantilever lever 5 rotates includes a vector component opposite to the direction of movement of the tail sleeve 4. The action of the locking structure 6 can be linear movement, rotational movement, or a combination of both, but its direction of movement includes a component opposite to the direction of movement of the tail sleeve 4. For example, when the tail sleeve 4 moves outward along the axial direction of the fiber optic connector 1, the action of the locking structure 6 may include a radial movement component in the axial direction; or when the tail sleeve 4 moves obliquely, the action of the locking structure 6 may include a movement component opposite to the oblique direction.

[0059] In this embodiment, the action of the locking structure 6 refers to the displacement or state change of the locking structure 6 when the cantilever lever 5 rotates. The action can include various forms of motion, such as linear motion, curvilinear motion, rotational motion, or a combination of these motions. The action of the locking structure 6 is intended to achieve the connection or release function with the adapter 2. For example, the action of the locking structure 6 can include radial movement of the locking structure 6 towards the axis of the fiber optic connector 1 to achieve release, or rotation of the locking structure 6 about its own axis to achieve unlocking.

[0060] In this embodiment, the component in the direction opposite to the movement direction of the tail sleeve 4 refers to the projection component of the locking structure 6's action direction vector in the opposite direction to the movement direction of the tail sleeve 4. This component indicates that the action of the locking structure 6 is at least partially opposite to the movement direction of the tail sleeve 4, forming a reverse motion relationship. For example, when the tail sleeve 4 moves outward along the axial direction, the locking structure 6 may generate an inward radial movement component; or when the tail sleeve 4 moves in the second direction, the locking structure 6 may generate a rotational component in the first direction. This reverse motion relationship achieves force transmission and direction conversion through the rotation of the cantilever lever 5.

[0061] Thus, when the tail sleeve 4 moves linearly and drives the cantilever lever 5 to rotate via mechanical coupling, the locking structure 6 will generate a reverse displacement. This reverse component of the action allows the locking structure 6 to lock or release in the opposite direction of operation, thereby effectively controlling the connector's connection status by operating only the tail sleeve 4 within a compact space.

[0062] Optionally, the locking structure 6 is located at the end of the cantilever lever 5 away from the tail sleeve 4; wherein, when the tail sleeve 4 moves in a preset direction along the side away from the cantilever lever 5, the end of the cantilever lever 5 away from the tail sleeve 4 rotates toward the axis of the fiber optic connector 1, and the locking structure 6 can be released from the adapter 2; when the tail sleeve 4 moves in a preset direction along the side of the cantilever lever 5, the end of the cantilever lever 5 away from the tail sleeve 4 rotates toward the axis of the fiber optic connector 1, and the locking structure 6 can be locked with the adapter 2.

[0063] In this embodiment, the locking structure 6 is located at the end of the cantilever lever 5 away from the tail sleeve 4 and / or the second sliding surface 51. The locking structure 6 is a double-inverted buckle 63 structure, used to engage with the slot inside the adapter 2 in the locked state. The double inverted buckles 63 of the locking structure 6 can be symmetrically arranged at the end of the U-shaped cantilever lever 5 away from the tail sleeve 4 (i.e., the side closer to the adapter 2), and the outer wall of the double inverted buckles 63 is provided with a guide slope 62 that gradually narrows along the insertion direction. When the fiber optic connector 1 is inserted into the adapter 2, the guide slope 62 of the double inverted buckles 63 engages with the guide structure of the inner wall of the adapter 2, causing the double inverted buckles 63 to be squeezed and deformed in the direction closer to the axis of the fiber optic connector 1. When the fiber optic connector 1 is inserted to the preset position, the double inverted buckles 63 are reset under the elastic restoring force of the U-shaped cantilever lever 5 and engage with the slot of the inner wall of the adapter 2, thereby locking the fiber optic connector 1 and the adapter 2. When the connector needs to be released, the operator can pull the tail sleeve 4 axially (away from adapter 2). The tail sleeve 4 pushes the root of the U-shaped cantilever lever 5 (the end near the second sliding surface 51) away from the surface of the connector body 3 via the first sliding surface 42. At the same time, the end of the U-shaped cantilever lever 5 away from the tail sleeve 4 (the end where the double buckles 63 are located) rotates towards the axis of the fiber optic connector 1. At this time, the double buckles 63 disengage from the slot of adapter 2 and are released from locking. The operator can then pull the tail sleeve 4 to remove the entire fiber optic connector 1 from adapter 2. When the tail sleeve 4 is released, the U-shaped cantilever lever 5 rotates in the opposite direction around the pivot point 33 under its own elastic restoring force, pushing the tail sleeve 4 back to its initial position axially. At the same time, the double buckles 63 reset to a state away from the axis, facilitating the next insertion and locking.

[0064] In this embodiment, the protruding structure 41 further includes a first plane 52 and a third sliding surface 53. One end of the first plane 52 is connected to the position of the first sliding surface 42 furthest from the surface of the connecting body 3, and the other end is connected to the position of the third sliding surface 53 furthest from the surface of the connecting body 3. The protruding structure 41 adds a first plane 52 between the first sliding surface 42 and the third sliding surface 53, and the two ends of the first plane 52 are respectively connected to the positions of the two sliding surfaces furthest from the surface of the connecting body 3, which can form a top platform higher than the surface of the body. When the tail sleeve 4 moves axially, the first sliding surface 42 first contacts the second sliding surface 51 of the cantilever lever 5 and pushes the lever to rotate. Then the first plane 52 briefly passes through the corresponding part of the lever, which can make the lever obtain a stable equal height holding area during rotation, avoiding abrupt changes in force or jamming caused by sudden changes in the slope.

[0065] In this embodiment, when the tail sleeve 4 moves in a preset direction away from the cantilever lever 5, the end of the cantilever lever 5 away from the tail sleeve 4 rotates towards the axis of the fiber optic connector 1. This means that the movement of the tail sleeve 4 drives the cantilever lever 5 to rotate around the pivot point 33 through mechanical coupling, causing the end of the cantilever lever 5 to produce a radially inward displacement. For example, when the tail sleeve 4 is pulled outward along the axial direction, the end of the cantilever lever 5 swings towards the axial direction; or when the tail sleeve 4 moves obliquely, the end of the cantilever lever 5 tilts towards the axial direction.

[0066] In this embodiment, when the tail sleeve 4 moves in a preset direction along the side closer to the cantilever lever 5, the end of the cantilever lever 5 away from the tail sleeve 4 rotates away from the axis of the fiber optic connector 1. This means that the movement of the tail sleeve 4 drives the cantilever lever 5 to rotate in the opposite direction around the pivot point 33 through mechanical coupling, causing the end of the cantilever lever 5 to produce a radially outward displacement. For example, when the tail sleeve 4 is pushed axially inward, the end of the cantilever lever 5 swings away from the axis; or when the tail sleeve 4 moves obliquely, the end of the cantilever lever 5 tilts away from the axis.

[0067] In this embodiment, the locking structure 6 being releaseable from the adapter 2 means that the locking structure 6 is disconnected from the adapter 2, allowing the fiber optic connector 1 to be pulled out of the adapter 2. The locking structure 6 being lockable to the adapter 2 means that the locking structure 6 forms a fixed connection with the adapter 2, preventing the fiber optic connector 1 from accidentally disengaging. For example, when released, the buckle 63 of the locking structure 6 disengages from the slot of the adapter 2; when locked, the protrusion of the locking structure 6 engages with the groove of the adapter 2.

[0068] Thus, since the locking structure 6 is located at the end of the cantilever lever 5 furthest from the tail sleeve 4, when the tail sleeve 4 is pulled outward in a preset direction, the first sliding surface 42 on its protruding structure 41 slides relative to the second sliding surface 51 of the cantilever lever 5. The lever is subjected to the lateral component force of the inclined plane and rotates around the fulcrum, causing the end furthest from the tail sleeve 4 to swing towards the connector axis. The locking structure 6 then retracts inward, thereby disengaging from the slot of the adapter 2 and completing the unlocking. Conversely, when the tail sleeve 4 is pushed back inward, the lever rotates in the opposite direction, the end opens outward, and the locking structure 6 extends outward and engages with the adapter 2, achieving locking. By setting the locking structure 6 at the farthest end of the lever, the axial displacement of the tail sleeve 4 is amplified into the radial travel of the locking structure 6, forming a significant force and displacement gain. The operator only needs to hold the tail sleeve 4 with one hand along the axial direction and make simple push and pull to complete the insertion and removal in the narrow space of the high-density patch panel, reducing the risk of squeezing adjacent connectors.

[0069] Optionally, the cantilever lever 5 has an elastic restoring force. When the tail sleeve 4 is pulled, the cantilever lever 5 overcomes the elastic restoring force and rotates away from the initial position. When the tail sleeve 4 is released, the elastic restoring force drives the cantilever lever 5 to rotate back to the initial position. When the cantilever lever 5 is in the initial position, the locking structure 6 is furthest from the axis of the fiber optic connector 1.

[0070] In this embodiment, the elastic restoring force of the cantilever lever 5 refers to its ability to automatically return to its original position after being rotated by an external force. The elastic restoring force can originate from the elastic properties of the material of the cantilever lever 5 itself, or from an elastic element connected to the cantilever lever 5. For example, the cantilever lever 5 may be made of a highly elastic metal material to provide the elastic restoring force, or the cantilever lever 5 may be connected to a helical spring to provide the elastic restoring force.

[0071] In this embodiment, when the tail sleeve 4 is pulled, the cantilever lever 5 overcomes the elastic restoring force and rotates away from the initial position. This means that the user applies a pulling force to the tail sleeve 4. This pulling force is transmitted through the mechanical coupling between the tail sleeve 4 and the cantilever lever 5, overcoming the elastic restoring force of the cantilever lever 5, causing the cantilever lever 5 to rotate around the rotation fulcrum 33 from the initial position to another position. For example, the protruding structure 41 of the tail sleeve 4 pushes the sliding surface of the cantilever lever 5, causing the cantilever lever 5 to rotate away from the initial position in the first direction; or the movement of the tail sleeve 4 drives the cantilever lever 5 to rotate away from the initial position through a linkage mechanism.

[0072] In this embodiment, when the tail sleeve 4 is released, the elastic restoring force driving the cantilever lever 5 to rotate back to its initial position means that after the user releases the pulling force on the tail sleeve 4, the elastic restoring force of the cantilever lever 5 acts as a driving force, causing the cantilever lever 5 to rotate around the rotation fulcrum 33 from its current position back to its initial position. For example, the cantilever lever 5 automatically springs back to its initial position due to the elasticity of its own material; or the cantilever lever 5 returns to its initial position under the restoring force of the compression spring.

[0073] In this embodiment, when the cantilever lever 5 is in its initial position, the locking structure 6 is furthest from the axis of the fiber optic connector 1. This means that in its natural state without external force, the locking structure 6 is in its outermost radial position to maximize locking contact with the adapter 2. For example, when the locking structure 6 is a double buckle 63, the tip of the double buckle 63 is furthest from the axis of the fiber optic connector 1 in the initial position; or when the locking structure 6 is a claw, the gripping part of the claw is furthest from the axis in the initial position.

[0074] In this way, the cantilever lever 5 possesses its own elastic restoring force. When the tail sleeve 4 is pulled, the cantilever lever 5 overcomes its own elasticity and rotates, causing the locking structure 6 to move closer to the connector axis, thereby completing the unlocking. Once the tail sleeve 4 is released, the elastic restoring force immediately drives the cantilever lever 5 to rotate in the opposite direction, causing the locking structure 6 to return to its initial position furthest from the axis of the fiber optic connector 1, and re-lock with the adapter 2. Through the elastic self-resetting design, the operator only needs to briefly pull the tail sleeve 4 with one hand to unlock. After releasing the hand, the connector automatically returns to the locked state without the need for an additional spring or manual reset action. At the same time, it ensures that the locking structure 6 maintains its maximum outward position under normal conditions, improving the reliability of the engagement with the adapter 2.

[0075] Optionally, the push-pull structure for the fiber optic connector 1 also includes a connecting body 3. The rotation fulcrum 33 of the cantilever lever 5 is disposed on the surface of the connecting body 3, and the tail sleeve 4 is fitted onto the connecting body 3.

[0076] In this embodiment, the connecting body 3 is a component of the push-pull structure for the fiber optic connector 1, providing structural support and component integration. The connecting body 3 can have various construction forms, such as a one-piece molded shell, a split frame, or a modular base, to adapt to the design requirements of different fiber optic connectors 1. For example, the connecting body 3 can be an injection-molded plastic body or a metal stamping support body.

[0077] In this embodiment, the rotation fulcrum 33 of the cantilever lever 5 being located on the surface of the connecting body 3 means that the rotation center of the cantilever lever 5 is located on the outer or inner surface of the connecting body 3. The rotation fulcrum 33 can be implemented in various ways, such as a protruding shaft structure, a recessed bearing structure, or a hinge connection structure, to support the stable rotation of the cantilever lever 5. For example, the rotation fulcrum 33 can be a cylindrical shaft protruding from the surface of the connecting body 3, or a circular groove formed on the surface of the connecting body 3.

[0078] In this embodiment, the tail sleeve 4 being fitted onto the connecting body 3 means that the tail sleeve 4 is installed outside or inside the connecting body 3 and is movable relative to the connecting body 3. The fitting method between the tail sleeve 4 and the connecting body 3 can include various mating forms, such as sliding fitting, guide rail fitting, or guide groove fitting, to ensure that the tail sleeve 4 moves in a preset direction. For example, the tail sleeve 4 can be fitted onto the cylindrical exterior of the connecting body 3 through a circular hole, or the tail sleeve 4 can be fitted into the guide groove of the connecting body 3 through an internal protrusion.

[0079] In this embodiment of the application, the connecting body 3 includes an upper body 31 and a lower body 32. The rotation fulcrum 33 of the cantilever lever 5 is located in the middle of the cantilever lever 5, and can be specifically set on the surface of the upper body 31.

[0080] In this embodiment, when the tail sleeve 4 is pulled to move along the axial direction of the fiber optic connector 1, the cantilever lever 5 can slide relative to the first sliding surface 42 of the tail sleeve 4 through the second sliding surface 51, causing the cantilever lever 5 to rotate in the first direction around the rotation fulcrum 33. When the cantilever lever 5 rotates in the first direction, the end of the cantilever lever 5 near the second sliding surface 51 is at least away from the surface of the connecting body 3, and the locking structure 6 is at least close to the surface of the connecting body 3.

[0081] In this embodiment, the cantilever lever 5 is a U-shaped cantilever lever 5 with its opening facing the front of the connecting body 3, and the second sliding surface 51 is disposed on the inner side of the root of the U-shaped cantilever lever 5.

[0082] In this way, by setting the connecting body 3 and placing the rotation fulcrum 33 of the cantilever lever 5 on the surface of the connecting body 3, while simultaneously fitting the tail sleeve 4 onto the connecting body 3, a stable and reliable support foundation is provided for the cantilever lever 5, and the tail sleeve 4 is ensured to move in a predetermined direction. As the core load-bearing structure, the connecting body 3 enables the rotation of the cantilever lever 5, the sliding of the tail sleeve 4, and the mechanical coupling between them to proceed precisely and in a coordinated manner, thereby improving the stability and reliability of the entire push-pull structure's movement.

[0083] Optionally, the connecting body 3 includes a displacement guide groove 34. At least a portion of the tail sleeve 4 is located within the displacement guide groove 34, allowing the tail sleeve 4 to move only in a preset direction.

[0084] In this embodiment, the displacement guide groove 34 is a guiding feature on the connecting body 3, used to limit the movement path of the tail sleeve 4. The displacement guide groove 34 can have various geometric shapes and configurations, such as straight grooves, arc grooves, or spiral grooves, to guide the tail sleeve 4 to move in a specific direction. For example, the displacement guide groove 34 can be an axial straight groove on the outer wall of the connecting body 3, or an annular guide groove on the inner side of the connecting body 3.

[0085] In this embodiment, "at least a portion of the tail sleeve 4 is located within the displacement guide groove 34" means that a specific area of ​​the tail sleeve 4 is embedded in or contacts the displacement guide groove 34 to form a guiding fit. This portion of the tail sleeve 4 may include various guiding elements, such as protrusions, bumps, or ribs, to interact with the inner wall or surface of the displacement guide groove 34. For example, the guiding protrusion of the tail sleeve 4 is embedded in the displacement guide groove 34, or the annular flange of the tail sleeve 4 is engaged in the displacement guide groove 34.

[0086] In this embodiment, restricting the tail sleeve 4 to move only in a preset direction means that the movement of the tail sleeve 4 is limited to a single direction or a specific path through the cooperation between the displacement guide groove 34 and the tail sleeve 4 structure. The preset direction can be a straight line, a curved line, or a combination thereof, but the constraint of the displacement guide groove 34 ensures that the tail sleeve 4 cannot freely deviate from this direction. For example, the sidewall of the displacement guide groove 34 prevents the tail sleeve 4 from moving radially or rotating, allowing the tail sleeve 4 to slide only along the axial direction of the fiber optic connector 1; or the guide rail structure of the displacement guide groove 34 restricts the tail sleeve 4 to move obliquely.

[0087] In this embodiment, the displacement guide groove 34 is disposed on the outer side wall of the connecting body 3 and extends along the axial direction of the fiber optic connector 1. The width of the groove is adapted to the guide protrusion on the inner side wall of the tail sleeve 4. The inner side wall of the tail sleeve 4 is provided with at least one guide protrusion extending along the axial direction. When the tail sleeve 4 is fitted on the outer side of the connecting body 3, the guide protrusion is embedded in the displacement guide groove 34 and can slide along the axial direction of the displacement guide groove 34.

[0088] In this embodiment, the displacement guide groove 34 may also be provided with limiting protrusions at both ends. The limiting protrusions extend inward into the displacement guide groove 34, and their height is less than the groove depth of the displacement guide groove 34. When the tail sleeve 4 moves axially to its maximum stroke, the guide protrusion of the tail sleeve 4 will abut against the limiting protrusion of the displacement guide groove 34, preventing the tail sleeve 4 from detaching from the connecting body 3 due to excessive pulling, and at the same time preventing the guide protrusion from rigidly colliding with the end of the displacement guide groove 34, which would cause structural damage. The limiting protrusions protruding towards each other on the inner sides of both ends of the displacement guide groove 34 are lower in height than the groove depth. When the tail sleeve 4 is pulled to its maximum stroke, its guide protrusions first elastically abut against the limiting protrusions instead of directly impacting the groove end. The impact is absorbed through local elastic deformation, and a clear tactile feedback is provided, preventing the tail sleeve 4 from continuing to move outward. This prevents the tail sleeve 4 from slipping off the connecting body 3 and also avoids rigid collision between the guide protrusion and the groove end, which could cause chipping or breakage. With its built-in flexible stop structure, the push-pull mechanism achieves overload protection while maintaining axial compactness. Maintenance personnel can operate quickly with one hand in the high-density patch panel without worrying about excessive force causing damage to parts, thus improving the connector's service life and field reliability.

[0089] Thus, the tail sleeve 4 needs to move along a preset direction to drive the cantilever lever 5 to rotate, thereby driving the locking structure 6 to move. The displacement guide groove 34 included in the connecting body 3 allows at least a portion of the tail sleeve 4 to be located within the groove. The displacement guide groove 34 physically constrains a portion of the tail sleeve 4, limiting its movement to the preset direction and preventing it from wobbling or shifting during pushing and pulling. This constraint ensures that the mechanical coupling between the tail sleeve 4 and the cantilever lever 5 remains stable. The linear movement of the tail sleeve 4 can be more reliably converted into the rotation of the cantilever lever 5 around the rotation fulcrum 33, reducing the failure of the connection or the jamming of the action caused by the offset of the tail sleeve 4, thereby making the action of the locking structure 6 more precise.

[0090] Optionally, the tail sleeve 4 is provided with at least one opening slot 43 on the side away from the cantilever lever 5, so that the tail sleeve 4 has elasticity along the axial direction of the fiber optic connector 1.

[0091] In this embodiment, the end of the tail sleeve 4 furthest from the cantilever lever 5 and / or the connecting body 3 is provided with multiple axially arranged opening slots 43 to increase the axial elasticity of the tail sleeve 4. The opening slots 43 can be evenly distributed along the axial direction of the tail sleeve 4, and the number of opening slots 43 can be adjusted according to the length of the tail sleeve 4. The depth and / or width of the opening slots 43 are determined according to the size of the tail sleeve 4. While ensuring the structural strength of the tail sleeve 4, the flexibility and axial elasticity of the tail sleeve 4 can be improved. When the fiber optic connector 1 is routed in a high-density patch panel, the tail sleeve 4 can adaptively deform according to the bending direction of the optical cable, avoiding excessive bending of the optical cable due to excessive rigidity of the tail sleeve 4, and at the same time facilitating the operator to hold the tail sleeve 4 for push-pull operations in a confined space. In addition, the outer wall of the tail sleeve 4 may be provided with anti-slip texture (such as mesh or diagonal texture). The anti-slip texture covers the middle gripping area of ​​the tail sleeve 4. When the operator manually pushes and pulls the tail sleeve 4, the anti-slip texture can increase the friction between the hand and the tail sleeve 4, and avoid slipping due to sweaty hands or the smooth surface of the tail sleeve 4, further improving the convenience of operation.

[0092] In this embodiment, the provision of at least one opening slot 43 on the side of the tail sleeve 4 away from the cantilever lever 5 means that one or more groove-like structures are formed in the area of ​​the tail sleeve 4 opposite to the cantilever lever 5. The opening slot 43 can have various shapes and sizes, such as U-shaped slots, V-shaped slots, or rectangular slots, to change the local structural characteristics of the tail sleeve 4. For example, the opening slot 43 can be a U-shaped cut at the end of the tail sleeve 4, or multiple rectangular openings on the side wall of the tail sleeve 4.

[0093] In the embodiments of this application, the configuration of the opening slot 43 includes, but is not limited to, a single long slot, multiple parallel slots, or a group of slots arranged in an alternating manner. The opening slot 43 can be arranged along the axial, circumferential, or other directions of the tail sleeve 4 to produce the desired elastic effect. For example, the opening slot 43 may include two symmetrical U-shaped slots at the end of the tail sleeve 4, or multiple rectangular slots evenly distributed circumferentially on the sidewall of the tail sleeve 4.

[0094] In this embodiment, giving the tail sleeve 4 elasticity along the axial direction of the fiber optic connector 1 means that by providing the opening slot 43, the tail sleeve 4 can produce recoverable deformation when subjected to axial force. This elasticity can manifest as axial compressive elasticity, tensile elasticity, or a combination thereof. For example, the opening slot 43 allows the tail sleeve 4 to elastically shorten under axial pressure or elastically elongate under axial tension; multiple circumferentially distributed opening slots 43 enable the tail sleeve 4 to produce uniform elastic deformation when subjected to axial force.

[0095] Thus, at least one opening slot 43 on the side of the tail sleeve 4 away from the cantilever lever 5 provides deformation space for the tail sleeve 4 in the axial direction along the fiber optic connector 1, making the tail sleeve 4 no longer rigid and thus possessing elasticity along the axial direction of the fiber optic connector 1. This axial elasticity allows the tail sleeve 4 to undergo slight adaptive deformation according to the gripping force when the operator holds it in the limited operating space of the high-density patch panel, improving the fit between the hand and the tail sleeve 4, reducing the possibility of slippage during operation, and making the pushing and pulling action smoother. Simultaneously, when the fiber optic connector 1 is being routed, if the optical cable bends to a certain extent, the axial elasticity of the tail sleeve 4 can adapt to the bending trend of the optical cable, avoiding excessive rigidity of the tail sleeve 4 that restricts the bending of the optical cable or causes excessive bending, thus protecting the optical cable structure. In addition, if the tail sleeve 4 is subjected to a slight radial disturbance force during its movement along the preset direction, its axial elasticity can play a certain buffering role, reducing the impact of the disturbance force on the fit between the tail sleeve 4 and the connecting body 3, and the mechanical coupling relationship between the tail sleeve 4 and the cantilever lever 5, ensuring that the tail sleeve 4 can move stably along the preset direction to drive the cantilever lever 5 to rotate, thereby ensuring the reliability of the locking structure 6's operation.

[0096] In some embodiments, the fiber optic connector 1 includes the push-pull structure described above for the fiber optic connector 1.

[0097] In this embodiment, the fiber optic connector 1 further includes at least one ferrule assembly 9. The at least one ferrule assembly 9 is disposed within the connector body 3; wherein, the ferrule assembly 9 includes a ferrule outer frame 10, a ferrule 11, a ferrule spring 12, and a spring limiting member 13; the ferrule 11 and the ferrule spring 12 are housed within the ferrule outer frame 10, and the spring limiting member 13 is disposed on the ferrule outer frame 10 to prevent the ferrule spring 12 from dislodging.

[0098] In this embodiment, a viewing window 8 is provided on the ferrule outer frame 10, through which the installation status of the spring limiting member 13 can be observed. The ferrule outer frame 10 is fixed inside the connecting body 3 by a snap-fit ​​structure 7. In this way, the viewing window 8 reserved on the side wall of the ferrule outer frame 10 and the snap-fit ​​structure 7 complement each other. During assembly, the snap-fit ​​structure 7 first quickly positions and fixes the ferrule outer frame 10 inside the connecting body 3 without the need for additional fasteners. Then, the operator can immediately see through the viewing window 8 whether the spring limiting member 13 has completely fallen into the slot, confirming that the ferrule spring 12 is reliably constrained. If the limiting member is found to be crooked or not in the slot, it can be reworked in time at the same work station, avoiding the cumbersome process of traditional closed structures requiring complete disassembly for inspection. By adopting the above verification method, the assembly cycle is shortened, the inspection cost is reduced, and each connector is ensured to reach a consistent spring preload state before leaving the factory, reducing the risk of ferrule 11 retraction due to limiting failure under subsequent high temperature or vibration environments, and improving the long-term stability of the optical fiber connection.

[0099] In this embodiment, the ferrule frame 10 is an integrally injection-molded structure with an internal receiving cavity extending along the axial direction of the fiber optic connector 1. The size of the receiving cavity is adapted to the shape of the ferrule 11 and the ferrule spring 12 for precise housing. A guide wedge 61 is provided on the outer wall of the ferrule frame 10. The guide wedge 61 tapers along the insertion direction of the ferrule frame 10 to facilitate the connection between the ferrule assembly 9 and the adapter 2. When the ferrule frame 10 is assembled to the connecting body 3, the tail of the ferrule frame 10 can engage with the corresponding connecting structure on the inner wall of the connecting body 3, assisting the ferrule frame 10 in quickly aligning and snapping into the connecting body 3, preventing misalignment or jamming during assembly. Simultaneously, a viewing window 8 is provided on the side wall of the ferrule frame 10, extending along the length of the ferrule frame 10 and communicating with the receiving cavity. Operators can directly observe the installation position of the spring limiter 13 in the receiving cavity and its contact with the ferrule spring 12 through the viewing window 8. Assembly and verification can be completed without disassembling the ferrule outer frame 10, effectively reducing the testing cost after assembly.

[0100] In this embodiment, one end of the ferrule 11 is an optical signal docking end, and the other end is a spring abutment end. When the ferrule 11 is assembled into the receiving cavity of the ferrule outer frame 10, its optical signal docking end can protrude a preset length from the end of the receiving cavity near the adapter 2. This preset length range ensures that the ferrule 11 and the corresponding ferrule 11 in the adapter 2 are accurately docked, avoiding collision damage due to excessive protrusion or interruption of optical signal transmission due to insufficient protrusion. The ferrule spring 12 is sleeved on the outside of the spring abutment end of the ferrule 11, and one end of the ferrule spring 12 abuts against the end face of the spring abutment end of the ferrule 11, and the other end abuts against the spring limiting member 13. When the ferrule 11 is subjected to the squeezing force of the adapter 2, the ferrule 11 can compress the ferrule spring 12 axially along the receiving cavity. The elastic restoring force of the ferrule spring 12 achieves a tight fit between the ferrule 11 and the adapter 2, improving the stability of optical signal transmission.

[0101] In this embodiment, the spring limiting member 13 is a sheet-like or block-like structure, and its shape is adapted to the opening end of the receiving cavity of the ferrule outer frame 10. After the ferrule 11 and the ferrule spring 12 are assembled, the spring limiting member 13 is inserted from the end of the receiving cavity away from the adapter 2 until the outer wall of the spring limiting member 13 is engaged and fixed with the inner wall of the receiving cavity (e.g., the spring limiting member 13 is provided with positioning protrusions, and the inner wall of the receiving cavity is provided with corresponding positioning slots, the two cooperate to prevent detachment). The thickness of the spring limiting member 13 is greater than the slot width at the opening end of the receiving cavity, which can effectively limit the ferrule spring 12 from sliding out of the receiving cavity in its natural or compressed state, while avoiding insufficient axial movement space of the ferrule 11 due to the excessive thickness of the spring limiting member 13. In addition, the outer wall of the ferrule outer frame 10 is also provided with a snap-fit ​​structure 7, and a connecting structure is provided at the corresponding position of the connecting body 3. When the outer frame 10 of the ferrule is inserted into the connecting body 3, the snap-fit ​​protrusion engages with the connecting structure, thereby enabling the outer frame 10 of the ferrule to be detachably fixed to the connecting body 3, which facilitates the replacement of the ferrule assembly 9 during later maintenance.
