Description

Technical Field

[0001] This application relates to the field of fiber optic connector technology, and for example to a push-pull structure for a fiber optic connector and a fiber optic connector. 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 first direction; a bidirectional displacement linkage wheel mechanically coupled to the tail sleeve; and a slider mechanically coupled to the bidirectional displacement linkage wheel and configured to move along a second direction different from the first direction; wherein the movement of the tail sleeve under external force is transmitted through the bidirectional displacement linkage wheel and converted into the movement of the slider, and the movement of the slider is used to drive the locking structure of the fiber optic connector.

[0009] Optionally, the bidirectional displacement linkage wheel is configured to convert the movement of the tail sleeve along a first direction into the movement of the slider along a second direction, and the angle between the first direction and the second direction is greater than 0 degrees.

[0010] Optionally, the push-pull structure for the fiber optic connector further includes a reset spring, one end of which abuts against the slider, for at least providing an elastic force to the slider to return to its initial position.

[0011] Optionally, the bidirectional displacement linkage wheel is rotatably mounted via a rotating shaft.

[0012] Optionally, the slider includes an inclined end face disposed on the side of the slider near the bidirectional displacement linkage wheel, the bidirectional displacement linkage wheel abutting against the inclined end face; wherein, when the slider slides along the second direction, the contact position between the bidirectional displacement linkage wheel and the inclined end face moves between the lowest point and the highest point of the inclined end face.

[0013] Optionally, the push-pull structure for the fiber optic connector further includes: a connection body, a tail sleeve, a bidirectional displacement linkage wheel, and a slider, at least one of which is configured to be mounted on the connection body of the fiber optic connector.

[0014] Optionally, the connecting body includes: a slide rail groove, and the slider is provided with a sliding groove adapted to the slide rail groove, the slide rail groove being at least partially embedded in the sliding groove, so that the slider can slide linearly along the second direction.

[0015] Optionally, the tail sleeve includes a guide groove disposed inside the tail sleeve; wherein the guide groove cooperates with a guide rib on the side of the connecting body near the optical fiber cable, so that the tail sleeve can move along the first direction.

[0016] Optionally, the slider includes a compression arm disposed on the slider surface for interacting with the locking structure of the fiber optic connector.

[0017] Optionally, the pressing arm is a protrusion or extension arm that extends from the surface of the slider toward the locking structure; wherein, when the slider moves in the second direction, the pressing arm can contact the outer wall of the locking structure and apply a pressing force, causing the locking structure to displace or deform in the direction close to the axis of the fiber optic connector, thereby releasing the locking structure from the adapter.

[0018] In some embodiments, the fiber optic connector includes: the push-pull structure described above for the fiber optic connector. The push-pull structure and fiber optic connector for fiber optic connectors provided in this disclosure can achieve the following technical effects: By moving the tail sleeve along a first direction, the mechanically coupled bidirectional displacement linkage wheel rotates, which in turn pushes the slider to move along a second direction different from the first direction. This converts the movement of the tail sleeve into the movement of the slider, which in turn drives the locking structure of the fiber optic connector, thus enabling tool-free insertion and removal of the connector. By changing the direction of movement, the operating parts are concentrated at the connector tail end, avoiding the compression of surrounding connectors due to limited operating space in high-density installation environments. This improves the convenience and reliability of operation, simplifies the operation steps, and increases the maintenance efficiency 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 1-6 As shown, this embodiment of the present disclosure provides an optical fiber connector 1 based on a bidirectional displacement linkage wheel 5, including a connecting body 3, a push-pull part, and a locking structure 8. The push-pull part includes a tail sleeve 4, a bidirectional displacement linkage wheel 5, a slider 6, and a return spring 7. The bidirectional displacement linkage wheel 5 is rotatably mounted on the surface of the connecting body 3 and has a first working end 51 and a second working end 52. The tail sleeve 4 is fitted onto the tail end of the connecting body 3 by moving along the axial direction of the fiber optic connector 1 and is connected to the first working end 51; the slider 6 is mounted on the surface of the connecting body 3 in a linear sliding manner and is connected to the second working end 52; the return spring 7 is located between the slider 6 and the connecting body 3 to provide elastic force to the slider 6 to return to its initial position; the locking structure 8 abuts against the slider 6 to achieve a fixed connection between the fiber optic connector 1 and the adapter 2; wherein, when the tail sleeve 4 is pulled, the tail sleeve 4 drives the bidirectional displacement linkage wheel 5 to rotate, the second working end 52 pushes the slider 6 to slide in the opposite direction to the movement direction of the tail sleeve 4, and causes the slider 6 to press the locking structure 8, so that the locking structure 8 is released from the adapter 2, thereby unlocking the fiber optic connector 1; when the tail sleeve 4 is released, the return spring 7 can drive the slider 6 to return to its initial position and drive the bidirectional displacement linkage wheel 5 to rotate in the opposite direction, so that the tail sleeve 4 returns to its original position synchronously.

[0031] In this embodiment, the axial direction refers to the straight line extending along the insertion / removal direction of the fiber optic connector 1, which is parallel to the center line of the ferrule 11. The movement of the tail sleeve 4, the slider 6, and the ferrule housing 10 are all along the axial direction to ensure that the fiber end faces remain coaxially aligned during mating.

[0032] In this embodiment, the axis refers to the geometric center line of the optical fiber connector 1, which is symmetrical. The axis passes through the center of the ferrule 11, the ferrule housing 10, the bidirectional displacement linkage wheel 5 and the tail sleeve 4. It is used to define the rotation center or sliding center of each component, so as to ensure that the locking structure 8 is subjected to symmetrical force during the release or locking process and avoid jamming caused by eccentricity.

[0033] In this embodiment, the slider 6 has an inclined end face 62 near the bidirectional displacement linkage wheel 5, and the second working end 52 of the bidirectional displacement linkage wheel 5 abuts against the inclined end face 62. One end of the return spring 7 abuts against the connecting body 3, and the other end abuts against a limiting surface provided inside the slider 6. The lowest point of the inclined end face 62 is the position farthest from the tail sleeve 4, and the highest point of the inclined end face 62 is the position closest to the tail sleeve 4. When the tail sleeve 4 is pulled, the slider 6 slides away from the tail sleeve 4 along the axial direction of the fiber optic connector 1. At this time, the return spring 7 is compressed by the limiting surface, and the second working end 52 moves from the lowest point of the inclined end face 62 to the highest point of the inclined end face 62. When the tail sleeve 4 is released, under the elastic restoring force of the return spring 7, the return spring 7 pushes the slider 6 to slide along the axial direction of the fiber optic connector 1 towards the tail sleeve 4 through the limiting surface. The second action end 52 can move from the highest point of the inclined end face 62 to the lowest point of the inclined end face 62 until the second action end 52 moves to the lowest point of the inclined end face 62.

[0034] In other embodiments, the tail sleeve 4 is configured to move along a first direction; the bidirectional displacement linkage wheel 5 is mechanically coupled to the tail sleeve 4; the slider 6 is mechanically coupled to the bidirectional displacement linkage wheel 5 and configured to move along a second direction different from the first direction. The movement of the tail sleeve 4 under external force is transmitted through the bidirectional displacement linkage wheel 5 and converted into movement of the slider 6. The movement of the slider 6 drives the locking structure 8 of the fiber optic connector 1. The first and / or second directions can be any direction, such as the axial direction, radial direction, or circumferential direction of the fiber optic connector 1, specifically related to the connection method between the bidirectional displacement linkage wheel 5 and the connecting body 3, the tail sleeve 4, and / or the slider 6, as well as the structure of the bidirectional displacement linkage wheel 5 itself. The actions include unlocking and locking.

[0035] The fiber optic connector 1 based on the bidirectional displacement linkage wheel 5 provided in this embodiment has a tail sleeve 4 that moves axially along the fiber optic connector 1 and is fitted onto the tail end of the connecting body 3. The tail sleeve 4 is connected to the first working end 51 of the bidirectional displacement linkage wheel 5, which is rotatably mounted on the surface of the connecting body 3. The second working end 52 of the bidirectional displacement linkage wheel 5 is connected to a slider 6, which is linearly slidably mounted on the surface of the connecting body 3. When the tail sleeve 4 is pulled, it drives the bidirectional displacement linkage wheel 5 to rotate. The rotating bidirectional displacement linkage wheel 5 pushes the slider 6 to slide in the opposite direction to the movement of the tail sleeve 4 via the second working end 52. The slider 6 abuts against the locking structure 8 used to fix the fiber optic connector 1 and the adapter 2. During the sliding process, the slider 6 squeezes the locking structure 8, causing it to release from the adapter 2, thus unlocking the fiber optic connector 1. The entire unlocking process only requires pulling the tail sleeve 4, eliminating the need for special tools and solving the problems of tool dependence or complex operation in related technologies. Meanwhile, the return spring 7 is located between the slider 6 and the connecting body 3, providing elastic force to the slider 6 to return to its initial position. When the tail sleeve 4 is released, the return spring 7 drives the slider 6 to return to its original position. The returned slider 6 then drives the bidirectional displacement linkage wheel 5 to rotate in the opposite direction, thus causing the tail sleeve 4 to return to its original position synchronously. This eliminates the need for operators to manually adjust the positions of the slider 6 and the tail sleeve 4, preparing for the next insertion or removal, further simplifying the operation process. In addition, the axial movement of the tail sleeve 4 and the linear sliding of the slider 6 are both achieved with stable movement relying on the connecting body 3. In the confined operating space of the high-density patch panel, operators only need to pull the tail sleeve 4 axially to unlock it, without the need for multi-directional or complex movements. This helps reduce the impact on adjacent connectors and better adapts to the usage requirements of high-density connection scenarios.

[0036] Optionally, the tail sleeve 4 and the slider 6 always move in opposite directions, and the tail sleeve 4 and the slider 6 achieve the change of movement direction through the bidirectional displacement linkage wheel 5.

[0037] In other embodiments, the bidirectional displacement linkage wheel 5 is configured to convert the movement of the tail sleeve 4 along a first direction into the movement of the slider 6 along a second direction, and the angle between the first and second directions is greater than 0 degrees, that is, the movement directions of the tail sleeve 4 and the slider 6 only need not coincide. For example, the angle between the first and second directions can be 180° (that is, the sliding direction of the slider 6 is always opposite to the movement direction of the tail sleeve 4) or the angle between the first and second directions can be 90° (that is, the sliding direction of the slider 6 is always perpendicular to the movement direction of the tail sleeve 4).

[0038] Thus, the bidirectional displacement linkage wheel 5 is rotatably mounted on the surface of the connecting body 3. Its first working end 51 is connected to the tail sleeve 4, which moves axially along the fiber optic connector 1, and its second working end 52 is connected to the slider 6, which is mounted in a linear sliding manner. When the operator pulls the tail sleeve 4 (moving axially away from the adapter 2), the tail sleeve 4 will drive the first working end 51 of the bidirectional displacement linkage wheel 5 to move synchronously, causing the bidirectional displacement linkage wheel 5 to rotate around the rotation center on the connecting body 3. The rotating bidirectional displacement linkage wheel 5 will push the slider 6 in the opposite direction to the movement direction of the tail sleeve 4 through the second working end 52. Slide towards (i.e., towards adapter 2); the above-mentioned motion direction conversion design concentrates the operation position of the tail sleeve 4 at the tail end of the connecting body 3, so that the operator does not need to find operating space on the side or top of the connector, which can effectively avoid squeezing the surrounding adjacent connectors in high-density arrangement scenarios. On the other hand, it allows the slider 6 to move precisely towards the locking structure 8 under the pull of the tail sleeve 4, thereby squeezing the locking structure 8 to unlock. The whole process does not require special tools. The slider 6 can be driven to slide in the opposite direction to complete the unlocking by simply pulling the tail sleeve 4, which greatly simplifies the operation steps.

[0039] Optionally, the bidirectional displacement linkage wheel 5 can be any one of an eccentric wheel, a cam, a double rocker arm, or a gear and rack combination structure, used to convert the linear displacement of the tail sleeve 4 into the reverse linear displacement of the slider 6.

[0040] In this embodiment, a mounting hole 53 is provided in the middle of the bidirectional displacement linkage wheel 5. The bidirectional displacement linkage wheel 5 can be connected to the rotating shaft 314 through the mounting hole 53, thereby being rotatably mounted on the surface of the connecting body. Specifically, the rotating shaft 314 can pass through the mounting hole 53 and fix the bidirectional displacement linkage wheel 5 to the surface of the upper body 31 of the connecting body 3 through the protruding structure at the end of the rotating shaft 314.

[0041] In this embodiment, the eccentric wheel can be engaged with the rotating shaft 314 on the surface of the connecting body 3 through the eccentric mounting hole 53 in the middle, so that the eccentric wheel can rotate around the rotating shaft 314. The first working end 51 of the eccentric wheel is connected to the tail sleeve 4, and the second working end 52 is connected to the slider 6. The displacement is transmitted by the change of eccentricity of the eccentric structure. The cam can form contact guidance with the first working end 51 and the second working end 52 through the contour curve of its outer periphery. When the first working end 51 moves linearly with the tail sleeve 4, it slides along the contour curve of the cam, driving the cam to move. The cam rotates around the pivot 314, and then pushes the second action end 52 through the contour of the other side of the cam to drive the slider 6 to move; the double rocker arm can be in the form of a rod structure, with the middle part hinged to the pivot 314 to form a lever fulcrum, and the two ends respectively serving as the first action end 51 and the second action end 52 connected to the tail sleeve 4 and the slider 6; the gear and rack combination structure can include mutually meshing gears and racks, the gears cooperating with the pivot 314 connecting the main body 3, and the racks can be respectively set on the tail sleeve 4 and the slider 6, and the gears transmit displacement through meshing with the racks on both sides.

[0042] In this way, when the tail sleeve 4 moves linearly along the axial direction of the fiber optic connector 1, it will drive the first working end 51 of the bidirectional displacement linkage wheel 5 to move linearly in sync. The eccentric wheel can convert the linear displacement of the tail sleeve 4 into the rotational motion of the bidirectional displacement linkage wheel 5 through the rotation of its own eccentric structure, the cam's guiding action through its contour curve, the double rocker arm's support through the lever principle, and the gear and rack combination structure's transmission through tooth meshing. The second working end 52 of the bidirectional displacement linkage wheel 5 then further converts this rotational motion into the linear displacement of the slider 6 in the opposite direction to the movement of the tail sleeve 4. Using one or more of these displacement conversion methods can effectively reduce jamming or offset problems during motion transmission, ensuring that the slider 6 can accurately slide towards the locking structure 8 to complete the compression unlocking. The availability of multiple structural types allows for selection of a suitable bidirectional displacement linkage wheel 5 structure based on different design requirements such as the overall size of the fiber optic connector 1, its internal space layout, and the required transmission efficiency. This enhances the flexibility of product design, and these structures all have a relatively compact shape, without occupying excessive internal or external space of the connector, making them suitable for the confined installation environment of high-density patch panels. Furthermore, the aforementioned displacement conversion process eliminates the need for complex intermediate transmission components, simplifying the overall structure of the push-pull section, reducing assembly difficulty, and allowing operators to obtain smoother action feedback when pulling the tail sleeve 4, reducing operating resistance and further improving ease of use.

[0043] Optionally, the connecting body 3 includes a limiting wall 311. The limiting wall 311 is disposed on the surface of the connecting body 3 near the locking structure 8; wherein, one end of the return spring 7 abuts against the slider 6, and the other end abuts against the limiting wall 311 of the connecting body 3, so as to provide a one-way elastic restoring force to the slider 6 when the tail sleeve 4 is released.

[0044] In this embodiment, the limiting wall 311 is a fixed structure on the connecting body 3, used to provide reverse support for the return spring 7 and limit its range of movement. The limiting wall 311 is disposed on the side of the connecting body 3 near the locking structure 8, and its function is to clamp the return spring 7 together with the slider 6, and to prevent the return spring 7 from moving away from the slider 6 when it is compressed. The specific form of the limiting wall 311 includes, but is not limited to, a boss, a wall panel, or a column. For example, the boss can be integrally formed with the connecting body 3 to form a supporting protrusion, and the wall panel can be vertically connected to the surface of the body to form a blocking surface.

[0045] In this embodiment, the contact between one end of the return spring 7 and the slider 6, and the contact between the other end and the limiting wall 311 of the connecting body 3, can adopt a contact method that ensures efficient force transmission. Specifically, it can include surface contact contact, point contact contact, etc. Surface contact contact can be achieved by providing a planar contact area on the end face of the slider 6 near the limiting wall 311 and a planar support area on the side of the limiting wall 311 near the slider 6, with both ends of the return spring 7 completely in contact with the aforementioned planar areas. Point contact contact can be achieved by providing a hemispherical protrusion on the end face of the slider 6 and a hemispherical groove on the side of the limiting wall 311, with both ends of the return spring 7 making point contact with the hemispherical protrusion and the hemispherical groove, respectively.

[0046] In this embodiment, the one-way elastic restoring force refers to the force generated by the return spring 7 after it is compressed along its axial direction, attempting to restore its original shape. The direction of this force is always along the direction that causes the slider 6 to return to its initial position. The one-way elastic restoring force is generated by the elastic deformation of the return spring 7, and its function is to drive the slider 6 to reset and indirectly drive the entire transmission chain to move in the opposite direction. The elastic element providing this restoring force includes, but is not limited to, a helical compression spring, a leaf spring, or an elastic colloid. For example, a helical compression spring stores energy through axial compression, and a leaf spring provides restoring force through bending deformation.

[0047] Thus, when the tail sleeve 4 is pulled, it drives the bidirectional displacement linkage wheel 5 to rotate. The second working end 52 of the bidirectional displacement linkage wheel 5 pushes the slider 6 to slide in the opposite direction to the movement direction of the tail sleeve 4. During this process, the slider 6 will compress the return spring 7. The limiting wall 311, as a fixed support point on the side of the return spring 7 away from the slider 6, can limit the deformation direction of the return spring 7, preventing the spring from shifting laterally or misaligning during compression, and ensuring that the return spring 7 can stably store elastic potential energy. When the tail sleeve 4 is released, the return spring 7, which has stored elastic potential energy, needs to release force to drive the slider 6 back to its initial position. The supporting effect of the limiting wall 311 allows the elastic force of the spring to be concentrated and transmitted along the sliding direction of the slider 6, forming a unidirectional elastic restoring force. This ensures that the slider 6 can smoothly return to its position along the preset path. When the slider 6 returns to its position, it will drive the bidirectional displacement linkage wheel 5 to rotate in the opposite direction, thereby causing the tail sleeve 4 to return to its position synchronously. This eliminates the need for operators to manually adjust the positions of the slider 6 and the tail sleeve 4, simplifying the operation process. Meanwhile, the placement of the limiting wall 311 near the locking structure 8 allows the installation space of the reset spring 7 to be closely fitted with the sliding path of the slider 6, without taking up too much extra space on the surface of the connecting body 3. This adapts to the narrow installation environment of high-density patch panels, and the stable transmission of unidirectional elastic restoring force reduces the collision of the slider 6 with other components on the surface of the connecting body 3 when it returns to its original position, thus improving the overall structural stability of the fiber optic connector 1.

[0048] Optionally, the tail sleeve 4 includes a guide groove. The guide groove is disposed inside the tail sleeve 4; wherein the guide groove cooperates with the guide rib 312 on the side of the connecting body 3 near the optical fiber cable, so that the tail sleeve 4 can move along the axial direction of the optical fiber connector 1.

[0049] In this embodiment, the guide groove of the tail sleeve 4 can adopt a long strip-shaped groove structure that can realize the guiding function, specifically including a rectangular groove, a trapezoidal groove, etc. The extension direction of the guide groove is consistent with the axial direction of the fiber optic connector 1 to ensure accurate guidance of the movement direction of the tail sleeve 4. Among them, the inner wall of the rectangular groove is a flat rectangular surface, and the groove width is adapted to the width of the guide rib 312 of the connecting body 3, which can reduce the frictional resistance when the guide rib 312 slides in the groove; the inner wall of the trapezoidal groove is a trapezoidal surface, and the groove width near the inner opening of the tail sleeve 4 is slightly larger than the width of the guide rib 312, while the groove width away from the opening is adapted to the width of the guide rib 312. It can play a guiding and positioning role when the guide rib 312 is embedded, and at the same time prevent the tail sleeve 4 from detaching from the guide rib 312 during movement. Both groove structures can stably cooperate with the guide rib 312 to realize the axial movement of the tail sleeve 4. The guide groove located inside the tail sleeve 4 can be either a through groove extending axially along the tail sleeve 4 or a semi-through groove extending axially along the tail sleeve 4. Neither of these configurations occupies space outside the tail sleeve 4, nor interferes with the assembly and movement of other components such as the bidirectional displacement linkage wheel 5 and the slider 6. The through groove extending axially along the tail sleeve 4 passes through both ends of the tail sleeve 4, facilitating the insertion of the guide rib 312 of the connecting body 3 from one end of the tail sleeve 4 and through the entire guide groove, thus accommodating the needs of longer guide ribs 312. The semi-through groove extending axially along the tail sleeve 4 opens only at the end of the tail sleeve 4 near the connecting body 3 and closes at the end away from the connecting body 3. This closes the maximum axial movement of the tail sleeve 4, preventing it from detaching from the connecting body 3 due to excessive movement and ensuring the stability of the fit. The fit structure between the guide groove and the guide rib 312 on the side of the connecting body 3 near the optical fiber cable can employ an adaptable structure that limits the radial offset of the tail sleeve 4 and guides its axial movement. Specifically, this can include a clearance fit structure, a transition fit structure, etc. In the clearance fit structure, the size of the guide groove is slightly larger than that of the guide rib 312, with a small gap between them. This reduces frictional loss between the guide rib 312 and the inner wall of the guide groove, and also prevents the tail sleeve 4 from getting stuck during axial movement. In the transition fit structure, the guide groove and the guide rib 312 have high dimensional accuracy, and the gap between them is extremely small. This further improves the stability of the tail sleeve 4 during movement and prevents the tail sleeve 4 from radially shaking due to slight collisions in high-density installation environments. Both fit structures ensure that the tail sleeve 4 moves only along the axial direction of the fiber optic connector 1.

[0050] In this embodiment, the tail sleeve 4 is provided with a receiving groove 41 near the connecting body 3 for accommodating the bidirectional displacement linkage wheel 5. The shape of the receiving groove 41 is adapted to the bidirectional displacement linkage wheel 5. A stop block 42 connected to the body of the tail sleeve 4 is provided at the end of the receiving groove 41. A fixed platform 43 with a lower surface than the stop block 42 and the body of the tail sleeve 4 is formed between the stop block 42 and the body of the tail sleeve 4. The first working end 51 of the bidirectional displacement linkage wheel 5 can be fixed on the fixed platform 43 formed between the stop block 42 and the body of the tail sleeve 4. Specifically, the first working end 51 of the bidirectional displacement linkage wheel 5 is a functional end that performs arc-shaped motion as the bidirectional displacement linkage wheel 5 rotates. Its connection to the tail sleeve 4 can be achieved through a motion-transmitting connection such as snap-fit, hinge, or sliding fit. For example, the first working end 51 can be snapped onto a pre-set fixed platform 43 inside the tail sleeve 4. When the tail sleeve 4 moves linearly along the axial direction of the fiber optic connector 1, the tail sleeve 4 drives the first working end 51 to move synchronously through the fixed platform 43. Due to the characteristic that the first working end 51 rotates around the axis 314 with the bidirectional displacement linkage wheel 5, this driving process is converted into the rotational motion of the bidirectional displacement linkage wheel 5. Alternatively, the first working end 51 can be hinged to the inner wall of the receiving groove 41 of the tail sleeve 4. When the tail sleeve 4 moves axially, a driving force is applied to the first working end 51 through the hinge point, causing the first working end 51 to perform arc-shaped motion around the axis 314, thereby driving the bidirectional displacement linkage wheel 5 to rotate, ensuring that the linear displacement of the tail sleeve 4 can be stably converted into the rotational motion of the bidirectional displacement linkage wheel 5.

[0051] In other embodiments, the guide groove cooperates with the guide rib 312 on the side of the connecting body 3 near the optical fiber cable, so that the tail sleeve 4 can move along the first direction.

[0052] Thus, the tail sleeve 4 includes a guide groove on its inner side, which cooperates with the guide rib 312 on the side of the connecting body 3 near the optical fiber cable. This effectively constrains the movement direction of the tail sleeve 4, preventing lateral offset or circumferential rotation of the tail sleeve 4 during its axial movement along the optical fiber connector 1, and ensuring that the tail sleeve 4 always moves smoothly along the preset axial path. Since the tail sleeve 4 is connected to the first working end 51 of the bidirectional displacement linkage wheel 5, the stable axial movement of the tail sleeve 4 can transmit a smooth and offset-free driving force to the bidirectional displacement linkage wheel 5, reducing the possibility of the bidirectional displacement linkage wheel 5 getting stuck or misaligned due to deviation in the movement direction of the tail sleeve 4. This ensures the accuracy of the action of the bidirectional displacement linkage wheel 5 when pushing the slider 6 through the second working end 52, allowing the slider 6 to move precisely towards the locking structure 8 to complete the squeezing unlock. Within the confined operating space of a high-density patch panel, the stable axial movement of the tail sleeve 4 eliminates the need for operators to adjust the direction of movement when pulling the tail sleeve 4. This reduces the probability of collisions with adjacent connectors due to tail sleeve 4 offset, improving operational convenience. Furthermore, the aforementioned guiding and mating structure eliminates the need for additional complex components, thus not increasing the overall volume of the connector. It can adapt to the space requirements of high-density installation environments, further ensuring the stability of the fiber optic connector 1 in high-density scenarios.

[0053] Optionally, the connecting body 3 includes a slide rail groove 313. The slide rail groove 313 is disposed on the surface of the connecting body 3 near the locking structure 8, and the limiting wall 311 is disposed at the end of the slide rail groove 313 near the locking structure 8; wherein, the slider 6 is provided with a sliding groove 63 that cooperates with the slide rail groove 313, the slide rail groove 313 is at least partially located in the sliding groove 63, the return spring 7 is at least partially located in the slide rail groove 313, and one end of the return spring 7 abuts against the limiting surface in the sliding groove 63 near the second working end 52, and the other end abuts against the limiting wall 311.

[0054] In this embodiment, the elastic restoring force of the reset spring 7 varies with the position of the second working end 52 on the inclined end face 62. When the position of the second working end 52 on the inclined end face 62 is higher, the elastic force of the reset spring 7 is greater. When the position of the second working end 52 on the inclined end face 62 is lower, the elastic force of the reset spring 7 is smaller.

[0055] In this embodiment, the sliding groove 63 is a recessed structure provided on the bottom or side of the slider 6, used to cooperate with the slide rail groove 313 on the surface of the connecting body 3, so that the slider 6 can slide linearly along the extension direction of the slide rail groove 313. The cross-sectional shape of the sliding groove 63 is adapted to the slide rail groove 313, including but not limited to rectangular groove, arc groove or polygonal groove. For example, the rectangular groove can form a surface contact sliding cooperation with the rectangular slide rail groove 313, the arc groove can form a rolling or sliding cooperation with the cylindrical slide rail groove 313, and the polygonal groove can form an anti-rotation cooperation with the corresponding polygonal slide rail groove 313. All kinds of groove structures can achieve stable cooperation and smooth sliding between the slider 6 and the slide rail groove 313.

[0056] In this embodiment, the return spring 7 is at least partially located within the slide rail groove 313. The placement of the return spring 7 within the slide rail groove 313 can be achieved through an installation method that adapts to the space of the slide rail groove 313 and ensures normal transmission of elastic force. This type of installation method can prevent the return spring 7 from twisting or misaligning during deformation. Installation methods include the return spring 7 being entirely embedded within the slide rail groove 313, with the limiting surface of the sliding groove 63 able to enter the slide rail groove 313 and fit against the end face of the return spring 7 as the slider 6 slides; or the return spring 7 being partially embedded within the slide rail groove 313, with the exposed portion fitting against the limiting surface of the sliding groove 63. When the return spring 7 is entirely embedded within the slide rail groove 313, the slide rail groove 313 can provide comprehensive protection for the return spring 7. When the return spring 7 is partially embedded within the slide rail groove 313, the depth requirement of the slide rail groove 313 can be reduced while ensuring stability, making it more suitable for the spatial layout of the surface of the connecting body 3.

[0057] In this way, the slide rail groove 313 is set on the side of the connecting body 3 near the locking structure 8, and the slider 6 is provided with a sliding groove 63 that cooperates with the slide rail groove 313, so that the slide rail groove 313 is at least partially located in the sliding groove 63. The above-mentioned cooperation structure can accurately constrain the movement trajectory of the slider 6, restricting the slider 6 to slide linearly only along the extension direction of the slide rail groove 313, avoiding lateral deviation or shaking of the slider 6 during the sliding towards the locking structure 8, ensuring that the slider 6 can stably and accurately approach and squeeze the locking structure 8, providing a basis for reliable triggering of the unlocking action. The limiting wall 311 is located at the end of the slide rail groove 313 near the locking structure 8. The return spring 7 is at least partially located in the slide rail groove 313, with one end abutting against the limiting surface in the slide groove 63 near the second action end 52 and the other end abutting against the limiting wall 311. The slide rail groove 313 can provide a closed and suitable installation space for the return spring 7, preventing the return spring 7 from being laterally misaligned or twisted when it is squeezed and contracted by the slider 6 or when it recovers its deformation by releasing the elastic force. This ensures that the elastic force of the return spring 7 is always transmitted in the direction of sliding of the slider 6. Thus, when the tail sleeve 4 is released, the return spring 7 can stably push the slider 6 back to the initial position along the slide rail groove 313. Furthermore, the supporting effect of the limiting wall 311 allows the elastic potential energy of the return spring 7 to be fully and stably released, avoiding loss of elastic force.

[0058] Optionally, the fiber optic connector 1 based on the bidirectional displacement linkage wheel 5 further includes a ferrule assembly 9, which includes a ferrule housing 10, a ferrule 11, and a ferrule spring 12. The ferrule housing 10 is at least partially assembled within the connecting body 3, and a locking structure 8 is disposed on the surface of the ferrule housing 10 located outside the connecting body 3; the ferrule 11 is disposed within the ferrule housing 10; and the ferrule spring 12 is disposed within the ferrule housing 10 and sleeved on the ferrule 11.

[0059] In this embodiment, the ferrule housing 10 can be at least partially fixedly assembled within the connecting body 3, or at least partially slidably assembled within the connecting body 3. The ferrule housing 10 being at least partially slidably assembled within the connecting body 3 allows the ferrule housing 10, along with the ferrule 11, to adaptively adjust its position within a certain range, facilitating the docking of the ferrule 11 with the corresponding component within the adapter 2. The sliding assembly method of the ferrule housing 10 includes a sliding fit or a guide rail fit. The sliding fit achieves linear sliding through the axial gap between the outer surface of the ferrule housing 10 and the inner wall of the connecting body 3. The guide rail fit achieves guided sliding through the interlocking of a guide groove on the inner wall of the connecting body 3 and a guide protrusion on the outer surface of the ferrule housing 10, ensuring stable axial movement of the ferrule housing 10 within the connecting body 3 while preventing radial offset.

[0060] Thus, the locking structure 8 is located on the surface of the ferrule housing 10 outside the connecting body 3. This position effectively corresponds to the slider 6 that slides along the surface of the connecting body 3, ensuring that the slider 6 can accurately press the locking structure 8 when sliding, thereby unlocking the fiber optic connector 1 and the adapter 2. The ferrule 11 is located inside the ferrule housing 10, which provides a stable installation and protection space for the ferrule 11, preventing it from shifting or being damaged due to external force collisions during insertion and removal. The ferrule spring 12, which is sleeved on the ferrule 11 and located inside the ferrule housing 10, provides elastic buffering force when the fiber optic connector 1 and the adapter 2 are mated, reducing the hard impact when the ferrule 11 and the adapter 2 are mated, and helping the ferrule 11 maintain a stable contact with the internal components of the adapter 2, thereby improving the stability of fiber optic signal transmission.

[0061] Optionally, the fiber optic connector 1 based on the bidirectional displacement linkage wheel 5 further includes a spring limiting block 13. The spring limiting block 13 is inserted into the side hole of the corresponding ferrule housing 10 to prevent the ferrule 11 and / or ferrule spring 12 from sliding out of the side hole, and at least a portion of the spring limiting block 13 is exposed on the surface of the ferrule housing 10 to form a visible installation indication.

[0062] In this embodiment, the spring limiting block 13 is inserted into the side hole of the corresponding ferrule housing 10. Specifically, it can be inserted into the opening channel on the wall of the ferrule housing 10 by axial movement. The insertion and fitting methods include, but are not limited to, interference fit, snap fit or threaded fit. For example, interference fit can be fixed by the dimensional interference between the spring limiting block 13 and the side hole. Snap fit can be fixed by the engagement of the elastic claw with the edge of the side hole. Threaded fit can be fixed by the engagement of the external thread of the spring limiting block 13 with the internal thread of the side hole.

[0063] In this embodiment, the spring limiting block 13 is used to prevent the ferrule 11 and / or the ferrule spring 12 from sliding out of the side hole. Its physical structure can prevent the internal components from axially disengaging along the side hole. The blocking can be achieved by end face blocking, radial interference, or axial locking. End face blocking can be achieved by the end area of ​​the spring limiting block 13 being larger than the cross-sectional area of ​​the side hole. Radial interference can be achieved by the spring limiting block 13 contacting the side wall of the internal component after insertion to limit movement. Axial locking can be achieved by the protrusion on the spring limiting block 13 engaging with the groove on the internal component to lock the position.

[0064] In this embodiment of the disclosure, at least a portion of the spring limiting block 13 being exposed on the surface of the ferrule housing 10 means that after installation, the spring limiting block 13 has an external area exposed outside the outer contour of the ferrule housing 10. The exposed portion includes, but is not limited to, a head, a marking portion, or a protrusion. The head can be designed as an operating portion larger than the diameter of the side hole to facilitate installation. The marking portion can be coated with a color different from the housing body to provide visual cues. The protrusion can form tactile feedback to facilitate touch recognition. Various forms of exposure can constitute a visual installation indication for intuitively judging the installation status of the spring limiting block 13.

[0065] In this way, after the spring limiting block 13 is inserted into the side hole of the corresponding ferrule housing 10, it will form a physical block at the side hole, directly restricting the ferrule 11 and / or ferrule spring 12 from moving out of the side hole. This prevents the ferrule 11 and ferrule spring 12 from sliding out of the side hole during connector insertion, removal, or use, thereby maintaining the complete assembly state of the ferrule assembly 9. This ensures that the ferrule 11 can be stably located inside the ferrule housing 10, and that the ferrule spring 12 can be properly fitted onto the ferrule 11 and play an elastic buffering role, providing a foundation for the stability of fiber optic splicing and signal transmission. At least a portion of the spring limiting block 13 is exposed on the surface of the ferrule housing 10. Operators can quickly determine whether the spring limiting block 13 has been correctly inserted by observing the presence and state of the exposed portion, without the need for additional tools to check the internal installation. This reduces subsequent failures caused by improper installation of the spring limiting block 13, improves the inspection efficiency during connector assembly, and further ensures the overall assembly quality and reliability of the fiber optic connector 1.

[0066] Optionally, the fiber optic connector 1 based on the bidirectional displacement linkage wheel 5 also includes a compression arm 61. The compression arm 61 is disposed on the surface of the slider 6 near the locking structure 8. The compression arm 61 can act on the locking structure 8 on the surface of the ferrule housing 10, causing the locking structure 8 to move at least along the axis near the fiber connector, so as to release the locking structure 8 from the adapter 2.

[0067] In this embodiment, there may be one or more ferrule assemblies 9, for example, there may be one, two, three or more ferrule assemblies 9. When the fiber optic connector 1 based on the bidirectional displacement linkage wheel 5 is provided with a predetermined number of ferrule assemblies 9, the inner side of the connecting body 3 is provided with a predetermined number of receiving cavities for at least partially accommodating the ferrule assemblies 9. Correspondingly, there are also predetermined numbers of locking structures 8 and pressing arms 61 corresponding to the locking structures 8.

[0068] In this embodiment, the locking structure 8 includes at least one locking arm. One end of the locking arm is fixed to the ferrule housing 10, and the other end is provided with a latching portion that can engage with the corresponding slot of the adapter 2. The locking arm is elastic and can undergo elastic deformation under the pressure of the slider 6, causing the latching portion to disengage from the slot of the adapter 2. The latching portion is provided with a guide slope to facilitate engagement and disengagement with the slot of the adapter 2. The locking structure 8 is integrally formed with the ferrule housing 10.

[0069] In other embodiments, the compression arm 61 is a protrusion or extension arm that extends from the surface of the slider 6 toward the locking structure 8; wherein, when the slider 6 moves in the second direction, the compression arm 61 can contact the outer wall of the locking structure 8 and apply a compression force, causing the locking structure 8 to be displaced or deformed in the direction close to the axis of the fiber optic connector 1, thereby releasing the locking structure 8 from the adapter 2.

[0070] In other embodiments, the compression arm 61 can be a rigid protrusion extending outward from the surface of the slider 6. The front end of the compression arm 61 can be provided with a wedge-shaped driving surface, which fits against the inclined surface of the outer wall of the locking structure 8 at an angle of 30 to 60 degrees. This is used to convert the axial movement of the slider 6 into radial movement of the locking structure 8 towards the axis of the fiber optic connector 1, thereby disengaging the locking structure 8 from the slot of the adapter 2. The compression arm 61 can also be an elastic cantilever beam structure. The root of the elastic cantilever beam is integrally formed with the slider 6, and the free end of the elastic cantilever beam is provided with a hemispherical contact. The hemispherical contact makes point contact with the outer wall of the locking structure 8. The bending deformation of the elastic cantilever beam absorbs the interference displacement, preventing the locking structure 8 from plastically deforming due to overpressure. The compression arm 61 can also be a detachable insert, which is fixed to the surface of the slider 6 by a buckle or screw. The buckle or screw fixing position has multiple adjustment positions along the longitudinal direction of the slider 6 to adapt to locking structures 8 of different heights, expanding the compatibility range of the fiber optic connector 1.

[0071] Thus, when the tail sleeve 4 is pulled to drive the bidirectional displacement linkage wheel 5 to rotate, thereby pushing the slider 6 to slide in the direction close to the locking structure 8, the slider 6 will drive the pressing arm 61 on its surface to move synchronously. Since the pressing arm 61 is close to the locking structure 8 and is set to correspond to the locking structure 8 on the surface of the ferrule housing 10, the moving pressing arm 61 will contact the locking structure 8 and apply force, causing the locking structure 8 to move at least along the side close to the axis of the fiber optic connector 1. This movement of the locking structure 8 can disengage it from the engagement state with the adapter 2, thereby releasing the fiber optic connector 1 from the adapter 2.

[0072] Optionally, the rotating shaft 314 of the bidirectional displacement linkage wheel 5 is integrally formed with the connecting body 3 or assembled separately; wherein the rotating shaft 314 is located on the symmetrical center line of the connecting body 3.

[0073] In this embodiment, the positioning layout of the rotating shaft 314 on the symmetrical center line of the connecting body 3 can adopt a central positioning form that ensures uniform force and smooth rotation of the bidirectional displacement linkage wheel 5. This central positioning form allows the bidirectional displacement linkage wheel 5 to rotate around the symmetrical center line of the connecting body 3, avoiding uneven force or movement jamming when the first action end 51 and the second action end 52 transmit displacement due to the offset of the rotation center. Common symmetrical center lines include the geometric symmetrical center line of the overall structure of the connecting body 3, the center reference line of a specific assembly area on the surface of the connecting body 3 used for assembling the bidirectional displacement linkage wheel 5, etc. When the connecting body 3 has a symmetrical structure, the rotating shaft 314 can coincide with the geometric symmetrical center line of the connecting body 3 to ensure overall force balance. When the local assembly area of ​​the connecting body 3 has an independent symmetrical structure, the rotating shaft 314 can coincide with the center reference line of the assembly area to adapt to the assembly requirements of the local structure. Both positioning forms can ensure that the bidirectional displacement linkage wheel 5 stably transmits the displacement between the tail sleeve 4 and the slider 6.

[0074] In this way, when the rotating shaft 314 and the connecting body 3 are integrally formed, the assembly gap between the two can be reduced, lowering the probability of the rotating shaft 314 becoming loose or shifting during use, and providing a stable rotational support for the bidirectional displacement linkage wheel 5. When a separate assembly method is adopted, it can flexibly adapt to the installation process of the bidirectional displacement linkage wheel 5, facilitating individual replacement or adjustment of components during production or maintenance, thus improving the convenience of production and maintenance. Simultaneously, the rotating shaft 314 is located on the symmetrical center line of the connecting body 3, ensuring that the rotation center of the bidirectional displacement linkage wheel 5 is consistent with the center of the connecting body 3. When the tail sleeve 4 drives the first action end 51 of the bidirectional displacement linkage wheel 5 to move, the linkage wheel can be evenly stressed and rotate smoothly around the symmetrical center line, avoiding uneven force or movement jamming when the second action end 52 pushes the slider 6 due to a shift in the rotation center. This ensures that the slider 6 can slide stably along the preset direction to press the locking structure 8 to unlock.

[0075] Optionally, the connecting body 3 includes an upper body 31 and a lower body 32. At least one of the tail sleeve 4, the bidirectional displacement linkage wheel 5, and the slider 6 is installed on the upper body 31.

[0076] In this embodiment, the housing of the ferrule 11 is fixed on one side of the connecting body 3, and the optical fiber cable is fixed on the other side. The slide rail groove 313 is provided on the side of the upper body 31 near the housing of the ferrule 11; the rotating shaft 314 is provided in the middle position of the upper body 31, serving as the rotation center of the bidirectional displacement linkage wheel 5; the optical fiber cable and the guide groove of the tail sleeve 4 are connected to the side of the upper body 31 near the tail sleeve 4.

[0077] In this embodiment, after the upper body 31 and the lower body 32 are installed to form the connecting body 3, a corresponding number of mounting cavities for mounting the ferrule assembly 9 can be formed. A fixing structure matching the ferrule housing 10 is provided in the mounting cavity, and the ferrule assembly 9 is at least partially located in the mounting cavity and fixed to the fixing structure to complete the installation of the ferrule assembly 9.

[0078] In this embodiment, the upper body 31 and the lower body 32 are detachably connected by a snap-and-groove structure. The snap-and-groove structure includes an elastic snap or a rotary lock. The elastic snap is symmetrically arranged on both sides of the upper body 31 and snaps into the groove on the edge of the lower body 32. The rotary lock locks the upper body 31 and the lower body 32 by rotation, so that the tail sleeve 4, the bidirectional displacement linkage wheel 5 and the slider 6 are fixed to the upper body 31 as a whole and facilitate quick disassembly and maintenance.

[0079] In this way, the connecting body 3 is split into an upper body 31 and a lower body 32. At least one of the components, such as the tail sleeve 4, the bidirectional displacement linkage wheel 5, and the slider 6, can be pre-installed on the upper body 31. For example, the bidirectional displacement linkage wheel 5 can be installed on the surface of the upper body 31 via the rotating shaft 314, and the slider 6 can be matched with the slide rail groove 313 on the surface of the upper body 31, or the tail sleeve 4 can be matched with the guide rib 312 of the upper body 31. Then the upper body 31 and the lower body 32 can be assembled, which avoids the interference of component installation caused by the closed internal space of the integral connecting body 3, reduces the assembly difficulty and improves the assembly efficiency. The upper body 31 serves as a specific mounting carrier, providing a stable and precise positioning reference for the installed tail sleeve 4, bidirectional displacement linkage wheel 5, or slider 6. For example, it ensures that the position of the rotating shaft 314 of the bidirectional displacement linkage wheel 5 is fixed, so that when the tail sleeve 4 moves axially, it can accurately drive the bidirectional displacement linkage wheel 5 to rotate, thereby allowing the second working end 52 of the linkage wheel to accurately push the slider 6 to slide, reducing transmission jamming caused by installation deviations and ensuring smooth unlocking. In addition, the split structure also allows for a reasonable allocation of the internal space of the connecting body 3. The lower body 32 can be used to accommodate other functional components such as the insert assembly 9, while the upper body 31 focuses on supporting the core components of the push-pull section, avoiding spatial conflicts between different components.
