Description

Technical Field

[0001] The present application relates to the field of optical fiber technology, and in particular to optical fiber connectors and components. Background Art

[0002] Fiber optic connectors, also known as fiber optic active joints, are devices for detachable (active) connections between optical fibers. Fiber optic connectors are also an indispensable key component in optical communication systems. Their main function is to quickly and accurately connect two optical fibers to ensure that optical signals can be continuously transmitted between optical fibers to form an optical path. With the rapid development of information Internet and cloud services, the demand for fiber optic connectors is also growing rapidly. In the future, fiber optic connectors will be more miniaturized to meet the growing demand for connections. At the same time, with the continuous advancement and innovation of technology, the performance and reliability of fiber optic connectors will be further improved.

[0003] The existing technology still has the following problems: 1. Optical fibers come in a variety of specifications. Existing optical fiber connectors can only limit the position of optical fibers of one specification, resulting in different optical fiber connectors for optical fibers of different specifications, which increases the complexity of optical fiber connector selection and configuration. In addition, when artificial external force touches or shakes during use, the shaking may cause the optical fiber inside the optical fiber connector to loosen, making the connection between the optical fibers unstable, resulting in the signal being unable to be transmitted normally, and signal interruption or intermittent connection. Shaking may also cause axial misalignment between optical fibers, all of which will increase the transmission loss of the optical signal, requiring the optical fiber connector to be disassembled and reconnected, wasting time.

[0004] 2. Traditional fiber optic connectors fix the optical fiber inside the fiber optic connector to connect the two optical fibers. However, it is difficult to avoid dragging the fiber optic connector when it is in use, which can cause the optical fiber to fall off inside the fiber optic connector and prevent the optical fiber from forming an optical path. In addition, it is difficult to promptly detect the displacement of the optical fiber and the fiber optic connector when the optical fiber is dragged, causing the optical fiber path to malfunction, making it impossible to quickly check the cause of the optical fiber damage. Summary of the invention

[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Embodiment 1: See also Figure 1 and Figure 2 As shown, the optical fiber connector includes a shell 1, a card cover 2 is provided on the outer surface of the shell 1, an optical fiber cable 3 is provided in the inner cavity of the shell 1, and an optical fiber core 4 is fixedly sleeved inside and outside the optical fiber cable 3. A limiting component 5 is provided in the inner cavity of the shell 1, and protective components 6 are provided at both ends of the shell 1. The optical fiber cables 3 are fixed in the inner cavity of the limiting component 5, so that the fiber cores 4 of the two optical fiber cables 3 are connected. The limiting component 5 is used for flexibly limiting and adjusting the position of the optical fiber cables 3, and the protective component 6 is used for preventing them from falling off. The card cover 2 can be quickly disassembled from the shell 1 to facilitate maintenance of the inside of the shell 1. The card cover 2 can be made of transparent material to facilitate observation of the connection status of the optical fiber core 4 inside the shell 1.

[0023] See also Figure 3 , Figure 8 , Fig. 9 and Fig.10As shown, the limit assembly 5 includes a limit block 51, a support mechanism 52 is provided at the bottom end of the limit block 51, buffer mechanisms 53 are provided on both sides of the limit block 51, a vertical slide groove is provided on the outer surface of the shell 1, the buffer mechanism 53 is slidably connected to the slide groove of the shell 1, an adjustment ring 54 is rotatably connected to the inner cavity of the limit block 51, a driving groove 55 is provided on the outer surface of the adjustment ring 54, a convex strip 56 is fixedly installed on the outer surface of the limit block 51, a fixing mechanism 57 is provided on the outer surface of the limit block 51, and a first clamping block 58 is slidably connected to the outer surface of the convex strip 56. The outer surface of the clamp block 58 is fixedly mounted with a driving rod 59, and the driving rod 59 is slidably connected to the driving groove 55. The fixing mechanism 57 includes a second fixing block 571, and the second fixing block 571 is fixedly connected to the limit block 51. The inner cavity of the second fixing block 571 is slidably connected with an insertion rod 572, and a fixing ring 573 is fixedly mounted on the outer surface of the insertion rod 572. A third spring 574 is sleeved on the outer surface of the insertion rod 572, and the third spring 574 is located between the second fixing block 571 and the fixing ring 573. The outer surface of the adjusting ring 54 is provided with a plug hole 575, and the insertion rod 57 2 passes through the limit block 51 and engages with the insertion hole 575. When fixing the optical fiber cable 3, the fixing ring 573 is compressed by pulling the insertion rod 572 to compress the third spring 574. At this time, the insertion rod 572 and the insertion hole 575 are disengaged, and the optical fiber cable 3 passes through the inner cavity of the limit block 51. The adjusting ring 54 is rotated to make the driving groove 55 drive the driving rod 59 to move. The movement of the driving rod 59 drives the first clamping block 58 to move on the convex strip 56, so that the first clamping block 58 and the outer surface of the optical fiber cable 3 are in close contact. At this time, the insertion rod 572 is released. Under the elastic force of the third spring 574, the insertion rod 572 is The rod 572 is again engaged with the socket 575, so that the adjustment ring 54 is stabilized in the inner cavity of the limit block 51, so that the first clamp block 58 limits the optical fiber cable 3, the support mechanism 52 is used to adjust the height of the limit block 51, and the buffer mechanism 53 is used to flexibly limit the limit block 51, so that the limit block 51 can return to the away position when the housing 1 shakes, so that the two fiber cores 4 are always in a connected state. By controlling the rotation of the adjustment ring 54, the first clamp block 58 can limit the optical fiber cables 3 of different thicknesses, thereby improving the overall fault tolerance of the equipment.

[0024] See also Figure 4 , Figure 5 and Figure 6As shown, the support mechanism 52 includes a first connecting block 521, the inner cavity of the first connecting block 521 is rotatably connected to a first threaded rod 522, the upper surface of the first connecting block 521 is slidably connected to a slider 523, the outer surface of the slider 523 is fixedly installed with a fixing rod 524, the four corners of the first connecting block 521 are fixedly installed with a storage rod 525, the inner cavity of the storage rod 525 is slidably connected to a lifting rod 526, the upper surface of the lifting rod 526 is fixedly installed with an adjusting block 527, the lower surface of the adjusting block 527 is fixedly installed with a first fixing block 528, and the middle part of the upper surface of the adjusting block 527 is fixedly installed There is a connecting rod 529, the outer surface of the connecting rod 529 is sleeved with a first spring 5210, the first connecting block 521 is slidably connected to the inner wall of the housing 1, and the sliding direction is perpendicular to the direction of the optical fiber cable 3. The first spring 5210 on the outer surface of the connecting rod 529 is used for the overall flexible connection of the limit block 51 and the support mechanism 52. When the external force shakes, the limit block 51 quickly recovers and fits with the adjustment block 527 to restore the limit block 51 to its original position. The first threaded rod 522 and the slider 523 are connected by threads. The first threaded rod 522 is rotatably connected to the housing 1 and the protective component 6. The first fixed block 528 is The outer surface is provided with an oblique groove, the fixing rod 524 is slidably connected to the oblique groove, the connecting rod 529 is slidably connected to the limit block 51, the first spring 5210 is located between the connecting rod 529 and the inner wall of the limit block 51, and the adjustment block 527 is in close contact with the outer surface of the limit block 51. When the heights of the two fiber cores 4 are not aligned after the optical fiber cable 3 is installed, the height of the limit block 51 can be adjusted by adjusting the support mechanism 52 to realign the two fiber cores 4, and the housing 1 and the card cover 2 do not need to be disassembled, that is, by rotating the first threaded rod 522 to slide the slider 523 on the first connecting block 521, the slider 523 The movement drives the fixing rod 524 to slide in the inclined groove on the first fixing block 528. At this time, the height of the first fixing block 528 changes, that is, the lifting rod 526 slides in the inner cavity of the storage rod 525, so that the height of the adjustment block 527 changes. The upgrade of the adjustment block 527 drives the upgrade of the connecting rod 529, and the upgrade of the connecting rod 529 drives the limit block 51 to rise and fall. The height of the limit block 51 is usually changed by adjusting the supporting mechanism 52. When the fiber cores 4 are not aligned due to height, they can be adjusted through the supporting mechanism 52 to make the two fiber cores 4 accurately aligned, so as to form a passage between the fiber cores 4.

[0025] See also Figure 3 , Figure 4 and Figure 7As shown, the buffer mechanism 53 includes a buffer seat 531, the inner cavity of the buffer seat 531 is slidably connected to an adjusting disk 532, the inner cavity of the buffer seat 531 is connected to a second threaded rod 533 by threaded rotation, the inner cavity of the buffer seat 531 is slidably connected to a buffer rod 534, the inner cavity of the buffer seat 531 is provided with a second spring 535, and there are two second springs 535 in the inner cavity of one buffer seat 531, one of which is sleeved with the buffer rod 534, and the other is located between the adjusting disk 532 and the buffer rod 534, the two ends of the buffer seat 531 are slidably connected to a first pressure rod 536, the outer surface of the first pressure rod 536 is provided with a baffle 537, and the end of the buffer rod 534 away from the buffer seat 531 is fixedly installed with a connecting seat 538, and the outer surface of the connecting seat 538 is provided with There is a first button 539, an alarm 5310 is fixedly installed on the outer surface of the connecting seat 538, the baffle 537 is slidably connected to the outer surface of the shell 1, the buffer seat 531 is slidably connected to the inner wall of the shell 1, the first pressure rod 536 is slidably connected to the baffle 537, the first pressure rod 536 is aligned with the first button 539, the first button 539 is electrically connected to the alarm 5310, and the pressing of the first button 539 controls the alarm 5310 to sound an alarm, the second threaded rod 533 is rotatably connected to the adjusting disk 532, the connecting seat 538 is fixedly connected to the outer surface of the limit block 51, the first pressure rod 536 is slidably connected on the inner cavity slide groove of the shell 1, the buffer seat 531 and the baffle 537 are located on both sides of the shell 1, and the second threaded rod 533 is movable to the shell 1 The first pressure rod 536 is slidably connected to the housing 1, the first pressure rod 536 is slidably connected to the buffer seat 531, and there is a large friction between the first pressure rod 536 and the baffle 537, which ensures that after the first pressure rod 536 adjusts its position, the first pressure rod 536 can generate pressure on the first button 539 when the first button 539 moves. The buffer mechanism 53 is used to flexibly fix the limit block 51. When the fiber cores 4 are offset in the horizontal direction, the position of the limit block 51 can be corrected by the buffer mechanism 53 on one side of the limit block 51, that is, the second threaded rod 533 is rotated to move the second threaded rod 533 in the inner cavity of the buffer seat 531, and the movement of the second threaded rod 533 drives the adjustment disk 532 to slide in the inner cavity of the buffer seat 531, and the buffer seat 531 The sliding movement drives the adjusting plate 532 to squeeze the second spring 535, and at this time, the second spring 535 also squeezes the buffer rod 534, so that the two second springs 535 in the same inner cavity are compressed at the same time, so that the buffer rod 534 slides in the inner cavity of the buffer seat 531. At this time, the elastic force of the connecting seat 538 on the limit block 51 changes, that is, the squeezing force of the buffer mechanism 53 on both sides of the limit block 51 changes, so that the position of the limit block 51 is corrected, so that when the fiber core 4 is offset, the position of the limit block 51 is adjusted by adjusting the depth of the second threaded rod 533, and at the same time, the adjustment of the supporting mechanism 52 is coordinated, so that the limit block 51 can be adjusted when it is offset up, down, left, and right, so as to ensure that the misplaced fiber core 4 can be corrected without disassembling the outer shell 1 and the card cover 2.At the same time, the connection seat 538 is flexibly fixed to the limit block 51. When the shell 1 shakes, the limit block 51 shakes. At this time, the limit block 51 drives the connection seat 538 to move. The movement of the connection seat 538 drives the buffer rod 534 to slide in the inner cavity of the buffer seat 531, so that the first button 539 and the first pressure rod 536 are in contact, so that the first button 539 is squeezed. At this time, the alarm 5310 sounds an alarm when the first button 539 is pressed, which is convenient for reminding the user that a fault may occur, so as to perform quick maintenance. After the shaking is over, the elastic force of the second spring 535 restores the connection seat 538 to its original position, preventing the fiber cores 4 from being misaligned during shaking, so that the fiber cores 4 are always kept in their initial positions under the flexible fixation of the buffer mechanism 53 and the elastic force of the first spring 5210, thereby reducing the possibility of the fiber cores 4 being separated due to external forces. By moving the position of the first pressure rod 536 on the baffle 537, it is convenient to adjust the distance from the first pressure rod 536 to the first button 539, so that the alarm 5310 can sound an alarm at the set distance.

[0026] Embodiment 2: See also Fig.11 and Fig.12 As shown, the component includes a protection component 6, and the protection component 6 includes a protection cover 61. The outer surfaces of both sides of the protection cover 61 are slidably connected with blocks 62. The inner wall of the protection cover 61 is fixedly installed with a protection mechanism 63. Alarm mechanisms 64 are arranged on both sides of the protection cover 61. When in use, there is a little extra optical fiber cable 3 in the inner cavity of the protection cover 61. The optical fiber cable 3 is secondarily limited by the protection mechanism 63 to ensure that the protection mechanism 63 can offset the dragging force when the optical fiber cable 3 is dragged. That is, at this time, the protection cover 61 and the outer shell 1 are displaced, so that the alarm mechanism 64 sounds an alarm to avoid continued dragging that causes the fiber core 4 to be disconnected. The protection covers 61 at both ends of the outer shell 1 are pulled to remove the card cover 2 from the outer surface of the outer shell 1, so as to facilitate maintenance of the inside of the outer shell 1.

[0027] See also Fig.12 and Fig.14As shown, the protective mechanism 63 includes a fixing plate 631, the fixing plate 631 and the protective cover 61 are fixedly connected, the inner cavities at both ends of the fixing plate 631 are slidably connected with elastic rods 632, the outer surface of the elastic rod 632 is provided with a clamping hole 633, one end of the elastic rod 632 is fixedly connected with a second clamping block 634, the outer surface of the clamping hole 633 is sleeved with a fourth spring 635, the fourth spring 635 is located between the second threaded rod 533 and the fixing plate 631, when the elastic rod 632 moves, the clamping block 62 is clamped with the clamping hole 633, when the fiber core 4 is connected, the elastic rod 632 is pulled to make the clamping block 62 and the clamping hole 633 clamp, at this time, the distance between the second clamping blocks 634 is increased, and the optical fiber cable 3 is passed through the second The first clamp 58 limits the optical fiber cable 3 for the first time, and the clamping block 62 is moved to disengage the clamping block 62 and the clamping hole 633. Under the elastic force of the fourth spring 635, the second clamping block 634 clamps and fixes the optical fiber cable 3. When the optical fiber cores 4 are connected, the optical fiber cable 3 pre-stored between the protective cover 61 and the outer shell 1 can be slightly more. In this way, when the optical fiber cable 3 is accidentally dragged, the optical fiber cable 3 in the inner cavity of the outer shell 1 will not be affected. Only the protective cover 61 and the outer shell 1 are displaced under the clamping of the protective mechanism 63. At this time, the alarm mechanism 64 sounds an alarm to remind the user to pay attention to the strength to avoid the two optical fiber cores 4 from falling off.

[0028] See also Fig.11 , Fig.12 and Fig.13As shown, the alarm mechanism 64 includes a second connecting block 641, a speaker 642 is fixedly installed on the outer surface of the second connecting block 641, a second button 643 is arranged on the outer surface of the second connecting block 641, a sliding rod 644 is fixedly installed on the outer surface of the second connecting block 641, and a fifth spring 645 is sleeved on the outer surface of the sliding rod 644, a third fixing block 646 is fixedly installed on the outer surface of the protective cover 61, and a second pressure rod 647 is slidably connected to the inner cavity of the third fixing block 646, and the position of the second pressure rod 647 in the inner cavity of the third fixing block 646 is adjusted to facilitate the control of the alarm distance, the second connecting block 641 is fixedly connected to the housing 1, the second button 643 and the speaker 642 are electrically connected, and the pressing of the second button 643 controls the speaker 642 to sound an alarm, the second pressure rod 647 and the second button 643 are aligned, the sliding rod 644 and the protective cover 61 are slidably connected, and the fifth spring 645 is located between the protective cover 61 and the second connecting block 641. When the optical fiber cable 3 is pulled by an external force , since the protective mechanism 63 clamps and fixes the optical fiber cable 3, the pulling of the optical fiber cable 3 drives the protective mechanism 63 to move, and the movement of the protective mechanism 63 drives the protective cover 61 to move on the outer shell 1. At this time, the optical fiber cable 3 pre-stored in the inner cavity of the protective cover 61 is moving, and the optical fiber cable 3 in the inner cavity of the outer shell 1 is not affected. When the protective cover 61 moves, it drives the third fixing block 646 to move, and the movement of the third fixing block 646 drives the second pressure rod 647 to move, and the sliding rod 644 moves in the inner cavity of the protective cover 61, while the second connecting block 641 and the outer shell 1 are fixed. At this time, the second pressure rod 647 squeezes the second button 643, so that the speaker 642 sends an alarm to remind the staff that the optical fiber cable 3 is dragged under the external force, and reminds the staff to stop dragging in time to prevent the fiber core 4 from falling off. Under the elastic force of the fifth spring 645, the second connecting block 641 returns to its original position, so that the excess optical fiber cable 3 is still stored in the inner cavity of the protective cover 61, thereby realizing the protection of the optical fiber cable 3 when dragged.

[0029] In summary, by fixing the optical fiber cable 3 in the inner cavity of the limiting component 5, the fiber cores 4 of the two optical fiber cables 3 are connected. The limiting component 5 is used to flexibly limit and adjust the position of the optical fiber cable 3. The protective component 6 is used to prevent it from falling off. The card cover 2 can be quickly disassembled on the housing 1 for easy maintenance of the inside of the housing 1. The card cover 2 can be made of transparent material to facilitate observation of the connection status of the fiber core 4 inside the housing 1. When fixing the optical fiber cable 3, the fixing ring 573 is compressed by pulling the plug rod 572. At this time, the plug rod 572 and the plug hole 575 are disengaged, and the optical fiber cable 3 is passed through the inner cavity of the limiting block 51. The adjusting ring 54 is rotated to move the first clamping block 58 on the convex strip 56, so that the first clamping block 58 and the outer surface of the optical fiber cable 3 are in close contact. At this time, the plug rod 572 is released. Under the elastic force of the third spring 574, the plug rod 572 is again The first clamp 58 is used to limit the optical fiber cable 3. The support mechanism 52 is used to adjust the height of the limit block 51. The buffer mechanism 53 is used to flexibly limit the limit block 51, so that the limit block 51 can return to the away position when the housing 1 shakes, so that the two fiber cores 4 are always in a connected state. By controlling the rotation of the adjustment ring 54, the first clamp 58 can limit the optical fiber cables 3 of different thicknesses, thereby improving the overall fault tolerance of the equipment. The optical fiber cable 3 is limited for a second time by the protective mechanism 63 to ensure that when the optical fiber cable 3 is dragged, the protective mechanism 63 can offset the dragging force, that is, at this time, the protective cover 61 and the housing 1 are displaced, so that the alarm mechanism 64 sounds an alarm to avoid continued dragging that causes the fiber core 4 to be disconnected.
