Description

Technical Field

[0001] This invention relates to the field of optical fiber connection and optoelectronic device manufacturing technology, and in particular to an insertion and extraction force adjustment device for an optical fiber connection assembly. Background Technology

[0002] Fiber optic connectors are crucial connecting components in fiber optic communication equipment, optoelectronic devices, optical inspection equipment, and some display device manufacturing equipment. They typically establish detachable optical signal transmission paths using fiber optic connectors, adapter interfaces, and internal positioning structures. During fiber optic and optoelectronic device manufacturing, fiber optic connectors often require multiple insertions and removals to facilitate the assembly, testing, maintenance, and replacement of fiber optic modules. Therefore, the insertion and removal performance of connectors directly affects assembly efficiency and connection reliability.

[0003] Existing fiber optic connectors typically use fixed-size clips, locking mechanisms, or elastic limiting components to form a locking mechanism. Once manufactured, the locking position, elastic pressure, and contact depth of this type of structure are usually fixed, making it difficult to adjust the insertion and extraction resistance based on different connector sizes, structural tolerances, material elasticity, and actual assembly requirements. When manufacturing tolerances exist in the components or wear occurs over long-term use, significant differences in insertion and extraction forces can easily occur between different batches of fiber optic connectors.

[0004] When the locking effect is too small, the connection stability between the fiber optic connector and the interface decreases. When the equipment is subjected to vibration or the fiber is pulled by external force, the connector is prone to axial movement, or even loosening of the connection. When the locking effect is too large, a large external force needs to be applied during insertion and removal, which can easily increase the mechanical wear of the connector housing, locking parts and interface, and may cause the operator to generate a large instantaneous pulling force when pulling out the fiber optic connector. Summary of the Invention

[0005] This invention provides an insertion and extraction force adjustment device and method for optical fiber connectors, which solves the problem that some existing optical fiber connectors use a fixed locking structure, making it difficult to adjust the tightness after connection, which in turn makes it inconvenient to adjust the insertion and extraction resistance according to the assembly state. At the same time, the impact and radial off-center load generated during the insertion and extraction process can easily affect the stability of the connection position.

[0006] This invention is implemented as follows: an insertion / extraction force adjustment device and method for an optical fiber connector assembly, comprising an optical fiber connector body, an optical fiber, an adjustment mechanism, a connector, an interface, and a buffer mechanism. The connector is connected to one end of the optical fiber and can be optically coupled to the interface. The interface has a locking groove on its inner side. The adjustment mechanism includes a locking block, a support, an eccentric handle, a slider, a return spring, a transmission rod, an adjustment seat, a limiting member, and a roller. The locking block is rotatably connected to the support, the roller is rotatably connected to the inner side of the locking block, the slider is slidably connected to the support and abuts against the roller, the transmission rod is slidably connected to the support and fixedly connected to the slider, the return spring is sleeved on the outer side of the transmission rod, the eccentric handle is rotatably connected to the adjustment seat and abuts against the transmission rod, and the limiting member is used to adjust and limit the initial rotation position of the eccentric handle.

[0007] The eccentric handle drives the slider to move via a transmission rod, which in turn drives the locking block to rotate via rollers, thereby changing the tightness between the locking block and the locking groove and adjusting the insertion and extraction resistance of the connector.

[0008] Preferably, the eccentric handle is provided with an eccentric abutment at one end near the transmission rod, the eccentric abutment abutting part abutting with the end of the transmission rod, and the eccentric handle changes the axial pushing amount on the transmission rod through the eccentric abutment part when it rotates.

[0009] Preferably, the eccentric handle and the limiting member are axially slidingly engaged. The limiting member is provided with multiple limiting positions distributed circumferentially. The eccentric handle can move axially and disengage from the current limiting position, and can engage with another limiting position after circumferential rotation, so as to change the initial working angle of the eccentric handle and the effective pushing stroke of the transmission rod.

[0010] Preferably, the slider has an inclined guide surface on the side near the roller, the roller abuts against the inclined guide surface, and when the slider moves along the support, it pushes the roller to generate displacement through the inclined guide surface, thereby causing the locking block to rotate relative to the support.

[0011] Preferably, the locking block is provided with a pressing part that cooperates with the locking groove. When the moving distance of the slider changes, the rotation angle of the locking block and the depth of the pressing part entering the locking groove change accordingly, so as to adjust the contact pressure between the locking block and the locking groove.

[0012] Preferably, one end of the return spring is connected to the slider and the other end is connected to the support. It is used to drive the slider and the transmission rod to reset in the opposite direction when the eccentric handle reduces the pushing amount on the transmission rod, so as to reduce the tightness between the locking block and the locking groove.

[0013] Preferably, the buffer mechanism includes an installation sleeve, a flexible connector, a rubber buffer pad, a buffer block, and a buffer plate. The flexible connector is rotatably connected to the installation sleeve. Both ends of the flexible connector are connected to rubber buffer pads. The buffer block abuts against the flexible connector. The buffer plate is connected to the buffer block and can extend into the interior of the interface to provide flexible support for the connector when it is connected to the interface.

[0014] Preferably, it further includes an anti-bending sleeve, a positioning sleeve, an upper mounting shell, and a lower mounting shell. The anti-bending sleeve is connected between the optical fiber and the connector. The upper and lower mounting shells cooperate with each other to form the installation space of the adjustment mechanism. The positioning sleeve is disposed on the outside of the upper and lower mounting shells. The flexible connector can generate a slight attitude adjustment when the connector is subjected to radial force to compensate for the radial position deviation between the connector and the interface and maintain the optical coupling position of the optical fiber.

[0015] Preferably, a method for adjusting the insertion and extraction force of an optical fiber connector includes the following steps:

[0016] S1. Insert the buffer mechanism and connector into the interface. The buffer mechanism provides flexible support for the connector, so that the optical fiber corresponds to the optical transmission position in the interface.

[0017] S2. Rotate the eccentric handle to push the transmission rod to move, and the transmission rod will drive the slider to move along the support.

[0018] S3. The slider pushes the roller, causing the roller to rotate and press the locking block into the locking groove.

[0019] S4. Detect the insertion and extraction resistance of the fiber optic connection assembly. Based on the detection results, move the eccentric handle axially relative to the limiting part and perform circumferential displacement to change the initial working angle of the eccentric handle, the pushing stroke of the transmission rod, and the contact pressure between the locking block and the locking groove.

[0020] S5. After adjusting the insertion and removal resistance, detect the optical signal status transmitted through the connector and interface of the optical fiber, and compensate the coupling posture of the connector by the flexible displacement of the buffer mechanism so that the insertion and removal resistance and the optical signal transmission status meet the set requirements.

[0021] Preferably, in step S4, when the detected insertion / removal resistance is lower than the set range, the initial working angle of the eccentric handle is adjusted to increase the pushing stroke of the transmission rod, so that the slider increases the pushing amount on the roller and increases the contact pressure between the locking block and the locking groove; when the detected insertion / removal resistance is higher than the set range, the initial working angle of the eccentric handle is adjusted to reduce the pushing stroke of the transmission rod.

[0022] Preferably, in step S5, the optical signal intensity or optical transmission loss before and after adjustment is detected to determine the optical coupling state of the connector.

[0023] Compared with related technologies, the insertion and extraction force adjustment device and method for an optical fiber connection assembly provided by the present invention have the following advantages:

[0024] 1. The present invention forms a continuous transmission structure through an eccentric handle, a transmission rod, a slider, a roller, and a locking block. Rotating the eccentric handle can change the amount of movement of the transmission rod and the slider, and further adjust the depth and tightness of the locking block entering the locking groove, thereby adjusting the insertion and extraction resistance of the connector. This avoids the problem that the traditional connection structure only has a fixed locking state, and improves the applicability and connection reliability of fiber optic connection components of different specifications and different assembly states.

[0025] 2. The present invention forms an adjustable limiting structure by using an eccentric handle and a limiting component. Pressing and rotating the eccentric handle can change its initial working position, so that different limiting positions correspond to different effective eccentric pushing amounts, thereby changing the holding force and pull-out resistance after the connector is locked. The adjustment can be completed without disassembling the connecting components or replacing the locking components, which is convenient for assembling and debugging different batches of connecting components in the process of optical fiber manufacturing and optoelectronic device manufacturing.

[0026] 3. The present invention uses flexible connectors, rubber buffer pads and buffer blocks to form a buffer structure, which can absorb part of the axial impact during the insertion and removal of connectors, and flexibly compensate for slight radial deviations and angular skews, reducing the impact of rigid collisions and off-center loads on the connection position, which is conducive to maintaining the relative posture and optical coupling stability of the optical fiber connection area, and at the same time facilitates assembly and testing with tension and compression sensors or optical power detection equipment.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0038] Example:

[0039] A preferred embodiment of the fiber optic connector insertion / extraction force adjustment device provided by the present invention is as follows: Figures 1 to 8The diagram illustrates an insertion / extraction force adjustment device for an optical fiber connector assembly. It includes an optical fiber connector body 1, an optical fiber 2, an adjustment mechanism 3, a connector 4, an interface 5, and a buffer mechanism 6. One end of the optical fiber 2 is connected to the connector 4, and the connector 4 can be inserted into the interface 5 on the optical fiber connector body 1 to establish an optical signal transmission connection. The adjustment mechanism 3 is located in the connection area of ​​the connector 4 and is used to change the mechanical retention degree after the connector 4 is connected to the interface 5. The buffer mechanism 6 is located at the end of the connector 4 facing the interface 5 and is used to buffer insertion / extraction impacts and provide flexible compensation for slight positional deviations.

[0040] In this embodiment, the fiber optic connection device body 1 can be a fiber optic communication device, a photoelectric conversion device, an optical inspection device, or an optoelectronic device with a fiber optic interface, which can be applied to fiber optic manufacturing, optoelectronic device manufacturing, and related fiber optic component assembly and inspection scenarios.

[0041] In a further preferred embodiment of the present invention, the adjusting mechanism 3 includes a locking block 302, a support 303, an eccentric handle 304, a slider 305, a return spring 306, a transmission rod 307, an adjusting seat 308, a limiting member 309, and a roller 310. The interface 5 is provided with a locking groove 301 corresponding to the position of the locking block 302. The locking block 302 is rotatably connected to the top of the support 303, the roller 310 is rotatably connected to the inner side of the locking block 302, and the slider 305 is slidably connected to the outer side of the support 303. The slider 305 forms an inclined guide surface towards the roller 310, and the roller 310 abuts against the inclined guide surface.

[0042] In this embodiment, the transmission rod 307 is slidably connected to the middle of the support 303. One end of the transmission rod 307 is fixedly connected to the slider 305. The return spring 306 is sleeved on the outside of the transmission rod 307. One end of the return spring 306 is connected to the slider 305, and the other end is connected to the support 303. When the transmission rod 307 moves axially, it can drive the slider 305 to move synchronously. The slider 305 pushes the roller 310 through the inclined guide surface, causing the roller 310 to drive the locking block 302 to rotate around the support 303, thereby converting the linear motion of the transmission rod 307 into the rotational motion of the locking block 302.

[0043] In a further preferred embodiment of the present invention, the adjusting seat 308 is fixedly connected to the outside of the support 303, the eccentric handle 304 is rotatably connected to the adjusting seat 308, and the limiting member 309 is connected to the adjusting seat 308 and cooperates with the eccentric handle 304. An eccentric abutment portion is formed at the end of the eccentric handle 304 near the transmission rod 307, and the eccentric abutment portion abuts against the end of the transmission rod 307. When the eccentric handle 304 rotates, the effective radius of the eccentric abutment portion changes, thereby pushing the transmission rod 307 to move along the support 303.

[0044] When the eccentric handle 304 is rotated in the locking direction, the transmission rod 307 drives the slider 305 to move towards the roller 310. The slider 305 pushes the roller 310 and drives the locking block 302 to rotate, causing the pressing part of the locking block 302 to enter the locking groove 301. As the sliding distance of the slider 305 increases, the rotation angle of the locking block 302 and the depth of its entry into the locking groove 301 also increase, thereby increasing the mechanical resistance that needs to be overcome when the connector 4 is pulled out.

[0045] In this embodiment, the limiting member 309 can form multiple limiting positions distributed circumferentially. When it is necessary to change the insertion and extraction resistance, the eccentric handle 304 can be pressed axially to disengage the eccentric handle 304 from the current limiting position, and then the eccentric handle 304 can be rotated to change its initial working angle. Subsequently, the eccentric handle 304 can be re-engaged with another limiting position of the limiting member 309. This changes the final pushing amount of the eccentric abutment part on the transmission rod 307.

[0046] When the pull-out resistance of connector 4 is too low, the eccentric handle 304 can be adjusted to a position with a larger effective pushing amount, increasing the moving distance of transmission rod 307 and slider 305, and improving the clamping degree between locking block 302 and locking groove 301. When the pull-out resistance is too high, the eccentric handle 304 can be adjusted to a position with a smaller effective pushing amount, reducing the rotation angle of locking block 302, thereby reducing the pull-out resistance. Through the above structure, connector 4 can not only achieve locking and unlocking, but also adjust the insertion and extraction resistance after locking according to assembly requirements.

[0047] In a further preferred embodiment of the present invention, the buffer mechanism 6 includes a mounting sleeve 601, a flexible connector 602, a rubber buffer pad 603, a buffer block 604, and a buffer plate 605. The flexible connector 602 is movably connected to the inner side of the mounting sleeve 601, and rubber buffer pads 603 are provided at both ends of the flexible connector 602. The buffer block 604 is provided on the side of the flexible connector 602 near the interface 5. The buffer plate 605 is fixedly connected to the buffer block 604 and can extend into the interface 5 along with the connector 4.

[0048] In this embodiment, when there is a slight radial or angular deviation between the connector 4 and the interface 5, the flexible connector 602 can deflect slightly relative to the mounting sleeve 601. The corresponding rubber buffer pad 603 undergoes elastic compression to absorb the impact generated during insertion and limit the deflection amplitude. When the external off-center load decreases, the rubber buffer pad 603 uses its elastic recovery to push the flexible connector 602 towards its initial position. The buffer block 604 further transmits and buffers the local load during the connection process, thereby reducing the likelihood of the connector 4 directly and rigidly impacting the internal structure of the interface 5.

[0049] Since the optical signal of optical fiber 2 needs to be transmitted through the connection area corresponding to connector 4 and interface 5, buffer mechanism 6 can reduce the adverse effects of radial off-center load and insertion / removal impact on the connection posture, which is conducive to maintaining the mechanical stability and optical coupling state of the optical fiber connection area.

[0050] In a further preferred embodiment of the present invention, the invention further includes an anti-bending sleeve 7, a positioning sleeve 8, an upper mounting shell 9, and a lower mounting shell 10. The anti-bending sleeve 7 is disposed near the connector 4 on the optical fiber 2 and is used to protect the connection root between the optical fiber 2 and the connector 4 from bending. The upper mounting shell 9 and the lower mounting shell 10 are interlocked to form an installation space, and the adjustment mechanism 3 is at least partially installed in this installation space. The positioning sleeve 8 is sleeved on the outside of the upper mounting shell 9 and the lower mounting shell 10 to limit their relative positions.

[0051] In actual use, the connector 4 and the buffer mechanism 6 are first inserted into the interface 5. The buffer mechanism 6 provides flexible buffering against slight positional deviations and impacts during the insertion process. After the connector 4 is inserted into place, the eccentric handle 304 is rotated. The eccentric handle 304 sequentially pushes the transmission rod 307 and the slider 305 to move. The slider 305 drives the locking block 302 into the locking groove 301 through the roller 310, thereby completing the connection and locking.

[0052] When it is necessary to pull out the connector 4, rotate the eccentric handle 304 in the opposite direction to reduce the pushing effect of the eccentric handle 304 on the transmission rod 307. The return spring 306 pushes the transmission rod 307 and the slider 305 to move in the opposite direction, so that the locking block 302 reduces the tightness between itself and the locking groove 301 or exits the locking groove 301. Then the connector 4 can be pulled out from the interface 5.

[0053] During the manufacturing or assembly testing of fiber optic connector components, external tension and compression sensors can be used to detect the axial force during the insertion and extraction of connector 4, and the mating position of the eccentric handle 304 and the limiting member 309 can be adjusted based on the detection results. Furthermore, after connection is completed, optical power detection equipment can be used to detect the optical signal strength or insertion loss of fiber 2. These sensitive elements and sensor detection equipment serve as auxiliary equipment in the manufacturing and testing stations and do not affect the independent adjustment of insertion and extraction force achieved by this device through mechanical structure.

[0054] With the above structure, the insertion and extraction resistance between the connector 4 and the interface 5 can be changed without disassembling the adjustment mechanism 3 or replacing the locking component, and the buffer mechanism 6 is used to reduce insertion and extraction impact and radial deviation. It is suitable for optical fiber manufacturing, optoelectronic device manufacturing, optical fiber module assembly and related testing stations.

The method for adjusting the insertion and extraction force of an optical fiber connector according to claim 9, characterized in that: In step S4, when the detected insertion / removal resistance is lower than the set range, the initial working angle of the eccentric handle (304) is adjusted to increase the pushing stroke of the transmission rod (307), so that the slider (305) increases the pushing amount on the roller (310) and increases the contact pressure between the locking block (302) and the locking groove (301); when the detected insertion / removal resistance is higher than the set range, the initial working angle of the eccentric handle (304) is adjusted to decrease the pushing stroke of the transmission rod (307); In step S5, the optical signal intensity or optical transmission loss before and after adjustment is detected to determine the optical coupling state of the connector (4).
