Description

Technical Field

[0001] This application relates to the field of optical fiber technology, and particularly to optical fiber connectors and components. Background Art

[0002] An optical fiber connector, also known as an optical fiber flexible joint, is a device for detachable (flexible) connection between optical fibers. At the same time, optical fiber connectors are indispensable key components in optical communication systems. Their main function is to quickly and precisely connect two optical fibers to ensure that optical signals can be continuously transmitted between the optical fibers, forming an optical path. With the rapid development of the information Internet and cloud services, the demand for optical fiber connectors is also increasing rapidly. In the future, optical fiber connectors will be more miniaturized to meet the growing connection needs. At the same time, with the continuous progress and innovation of technology, the performance and reliability of optical fiber connectors will also be further improved.

[0003] Currently, the following problems still exist in the existing technology:

[0004] 1. There are various specifications of optical fibers. Existing optical fiber connectors can only limit one specification of optical fiber, resulting in different specifications of optical fibers requiring different optical fiber connectors, increasing the complexity of the selection and configuration of optical fiber connectors. In addition, during use, when subjected to external force touch or shaking by humans, the shaking may cause the optical fiber inside the optical fiber connector to become loose, making the connection between the optical fibers unstable, resulting in abnormal signal transmission, signal interruption, or intermittent connection. The shaking may also cause axial misalignment between the optical fibers, all of which will increase the transmission loss of optical signals, thus requiring the optical fiber connector to be disassembled and reconnected, wasting time.

[0005] 2. Traditional optical fiber connectors fix the optical fibers inside the optical fiber connector to connect two optical fibers. However, during use, it is difficult to avoid dragging the optical fiber connector, which may cause the optical fiber to fall off inside the optical fiber connector, preventing the formation of an optical path. In addition, it is difficult to detect the displacement of the optical fiber and the optical fiber connector in a timely manner during dragging, resulting in a failure of the optical fiber path and making it impossible to quickly check the cause of the optical fiber damage. Summary of the Invention

[0035] Regarding the looseness of the optical fibers inside the optical fiber connector, which makes the connection between the optical fibers unstable, the present invention can flexibly fix optical fibers of various specifications through the limiting component, and can prevent the optical fibers from displacing when the optical fiber connector shakes, so that the connection between the optical fibers is stable; regarding the difficulty in timely detecting the displacement of the optical fiber and the optical fiber connector when the optical fiber is dragged, the present invention can issue an alarm in time through the protection component when the optical fiber is dragged, reminding the staff to pay attention to the pulling of the optical fiber, and at the same time having a certain buffer distance for pulling to prevent the fiber core of the optical fiber from falling off.

[0036] In order to better understand the above technical solutions, the following will combine the specification drawings and specific implementation manners to elaborate on the above technical solutions in detail.

[0037] Example 1:

[0038] Please refer to Figure 1 and Figure 2As shown, the fiber optic connector includes a housing 1, a cover 2 is provided on the outer surface of the housing 1, a fiber optic cable 3 is provided in the inner cavity of the housing 1, a fiber core 4 is fixedly sleeved inside the fiber optic cable 3, a limiting component 5 is provided in the inner cavity of the housing 1, and protective components 6 are provided at both ends of the housing 1. By fixing the fiber optic cable 3 in the inner cavity of the limiting component 5, the fiber cores 4 of two fiber optic cables 3 are connected. The limiting component 5 is used for flexibly limiting and adjusting the position of the fiber optic cable 3, the protective components 6 are used for preventing detachment, the cover 2 can be quickly disassembled on the housing 1 to facilitate the maintenance of the inside of the housing 1, and the cover 2 can be made of a transparent material to facilitate observing the connection condition of the fiber core 4 inside the housing 1.

[0039] Please refer to Figure 3 、 Figure 8 、 Figure 9 and Figure 10As shown, the limit component 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. Vertical sliding grooves are formed on the outer surface of the outer shell 1. The buffer mechanisms 53 are slidably connected to the sliding grooves of the outer shell 1. An adjusting ring 54 is rotatably connected to the inner cavity of the limit block 51. A driving groove 55 is formed on the outer surface of the adjusting 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. The outer surface of the convex strip 56 is slidably connected to a first clamping block 58. A driving rod 59 is fixedly installed on the outer surface of the first clamping block 58. The driving rod 59 is slidably connected to the driving groove 55. The fixing mechanism 57 includes a second fixing block 571. The second fixing block 571 is fixedly connected to the limit block 51. A plug rod 572 is slidably connected to the inner cavity of the second fixing block 571. A fixing ring 573 is fixedly installed on the outer surface of the plug rod 572. A third spring 574 is sleeved on the outer surface of the plug rod 572. The third spring 574 is located between the second fixing block 571 and the fixing ring 573. A jack 575 is formed on the outer surface of the adjusting ring 54. The plug rod 572 passes through the limit block 51 and is engaged with the jack 575. When fixing the optical fiber cable 3, by pulling the plug rod 572, the fixing ring 573 compresses the third spring 574. At this time, the plug rod 572 is disengaged from the jack 575. The optical fiber cable 3 is passed through the inner cavity of the limit block 51. The adjusting ring 54 is rotated to drive the driving rod 59 to move by the driving groove 55. 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 is in close contact with the outer surface of the optical fiber cable 3. At this time, the plug rod 572 is released. Under the elastic force of the third spring 574, the plug rod 572 is engaged with the jack 575 again, so that the adjusting ring 54 is stabilized in the inner cavity of the limit block 51, and the first clamping block 58 limits 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 for flexible limiting of the limit block 51, so that the limit block 51 can return to the far position when the outer shell 1 shakes, facilitating the two fiber cores 4 to always be in a connected state. By controlling the rotation of the adjusting ring 54, the first clamping block 58 can limit optical fiber cables 3 of different thicknesses, improving the overall fault tolerance of the device.

[0040] Please refer to Figure 4 、 Figure 5 and Figure 6As shown in the figure, the support mechanism 52 includes a first connection block 521. A first threaded rod 522 is rotatably connected to the inner cavity of the first connection block 521. A slider 523 is slidably connected to the upper surface of the first connection block 521. A fixed rod 524 is fixedly installed on the outer surface of the slider 523. Receiving rods 525 are fixedly installed at the four corners of the first connection block 521. A lifting rod 526 is slidably connected to the inner cavity of the receiving rod 525. An adjusting block 527 is fixedly installed on the upper surface of the lifting rod 526. A first fixing block 528 is fixedly installed on the lower surface of the adjusting block 527. A connecting rod 529 is fixedly installed at the middle part of the upper surface of the adjusting block 527. A first spring 5210 is sleeved on the outer surface of the connecting rod 529. The first connection block 521 is slidably connected to the inner wall of the housing 1, and the sliding direction is perpendicular to the direction where the optical fiber cable 3 is located. The first spring 5210 on the outer surface of the connecting rod 529 is used to flexibly connect the limiting block 51 and the entire support mechanism 52. When an external force causes shaking, the limiting block 51 quickly resumes contact with the adjusting block 527, so that the limiting block 51 returns to its original position. The first threaded rod 522 is threadedly connected to the slider 523, and the first threaded rod 522 is rotatably connected to both the housing 1 and the protection component 6. An inclined groove is formed on the outer surface of the first fixing block 528, and the fixed rod 524 is slidably connected to the inclined groove. The connecting rod 529 is slidably connected to the limiting block 51. The first spring 5210 is located between the inner walls of the connecting rod 529 and the limiting block 51. The outer surfaces of the adjusting block 527 and the limiting block 51 are in close contact. When the optical fiber cable 3 is installed and the heights between the two optical fiber cores 4 are not aligned, the height of the limiting block 51 can be adjusted by adjusting the support mechanism 52 so that the two optical fiber cores 4 are aligned again, and it is not necessary to disassemble the housing 1 and the cover 2. That is, by rotating the first threaded rod 522, the slider 523 slides on the first connection block 521. The movement of the slider 523 drives the fixed rod 524 to slide in the inclined groove of 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 receiving rod 525, so that the height of the adjusting block 527 changes. The lifting of the adjusting block 527 drives the lifting of the connecting rod 529. The lifting of the connecting rod 529 drives the limiting block 51 to lift. Usually, by adjusting the support mechanism 52, the height of the limiting block 51 changes. When the optical fiber cores 4 are not aligned due to height differences, they can be adjusted by the support mechanism 52, so that the two optical fiber cores 4 are accurately aligned, which is convenient for forming a path between the optical fiber cores 4.

[0041] Please refer to Figure 3 、 Figure 4 and Figure 7As shown in the figure, the buffer mechanism 53 includes a buffer seat 531. A regulating disc 532 is slidably connected to the inner cavity of the buffer seat 531. A second threaded rod 533 is rotationally connected to the inner cavity of the buffer seat 531 by means of threads. A buffer rod 534 is slidably connected to the inner cavity of the buffer seat 531. A second spring 535 is arranged in the inner cavity of the buffer seat 531, and there are two second springs 535 in the inner cavity of one buffer seat 531. One of them is sleeved on the buffer rod 534, and the other is located between the regulating disc 532 and the buffer rod 534. The two ends of the buffer seat 531 are slidably connected with a first pressure rod 536. A baffle 537 is arranged on the outer surface of the first pressure rod 536. One end of the buffer rod 534 away from the buffer seat 531 is fixedly installed with a connecting seat 538. A first button 539 is arranged on the outer surface of the connecting seat 538. An alarm 5310 is fixedly installed on the outer surface of the connecting seat 538. The baffle 537 is slidably connected with the outer surface of the housing 1 up and down. The buffer seat 531 is slidably connected with the inner wall of the housing 1 up and down. The first pressure rod 536 is slidably connected with the baffle 537. The first pressure rod 536 is aligned with the first button 539. The first button 539 is electrically connected with the alarm 5310, and pressing the first button 539 controls the alarm 5310 to give an alarm. The second threaded rod 533 is rotationally connected with the regulating disc 532. The connecting seat 538 is fixedly connected with the outer surface of the limiting block 51. The first pressure rod 536 is slidably connected with the inner cavity chute of the housing 1. The buffer seat 531 and the baffle 537 are located on both sides of the housing 1. The second threaded rod 533 is movably connected with the housing 1. The first pressure rod 536 is slidably connected with the housing 1. The first pressure rod 536 is slidably connected with the buffer seat 531. There is a large frictional force between the first pressure rod 536 and the baffle 537, ensuring that after the position of the first pressure rod 536 is adjusted, the first pressure rod 536 can exert pressure on the first button 539 when the first button 539 moves. The buffer mechanism 53 is used for flexibly fixing the limiting block 51. When the optical fibers 4 are offset in the horizontal direction, the position of the limiting block 51 can be corrected by the buffer mechanism 53 on one side of the limiting block 51, that is, by rotating the second threaded rod 533 to make the second threaded rod 533 move in the inner cavity of the buffer seat 531. The movement of the second threaded rod 533 drives the regulating disc 532 to slide in the inner cavity of the buffer seat 531. The sliding of the buffer seat 531 drives the regulating disc 532 to squeeze the second spring 535. 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 limiting block 51 changes, that is, the extrusion force of the buffer mechanisms 53 on both sides of the limiting block 51 changes, so as to correct the position of the limiting block 51, so that when the optical fibers 4 are offset, the position of the limiting block 51 is adjusted by adjusting the depth of the second threaded rod 533. At the same time, in cooperation with the adjustment of the support mechanism 52, the limiting block 51 can be adjusted when it is offset up, down, left and right, ensuring that the misaligned optical fibers 4 can be corrected without disassembling the housing 1 and the snap cover 2.Meanwhile, the connecting seat 538 flexibly fixes the limiting block 51. When the outer shell 1 shakes, the limiting block 51 shakes. At this time, the limiting block 51 drives the connecting seat 538 to move. The movement of the connecting seat 538 drives the buffer rod 534 to slide in the inner cavity of the buffer seat 531, so that the first button 539 contacts the first pressure rod 536, and the first button 539 is squeezed. At this time, the alarm 5310 emits an alarm under the pressing of the first button 539, which is convenient for reminding the user that a failure may occur, so as to perform quick maintenance. At the same time, after the shaking ends, the elastic force of the second spring 535 makes the connecting seat 538 return to its original position, preventing misalignment between the optical fibers 4 during shaking, so that the optical fibers 4 always maintain their initial positions under the flexible fixation of the buffer mechanism 53 and the elastic force of the first spring 5210, thereby reducing the situation of separation between the optical fibers 4 caused by external force. The distance between the first pressure rod 536 and the first button 539 can be adjusted by moving the position of the first pressure rod 536 on the baffle 537, so that the alarm 5310 emits an alarm at the set distance.,

[0042] Embodiment 2:

[0043] Please refer to Figure 11 and Figure 12 As shown, the assembly includes a protection component 6. The protection component 6 includes a protection cover 61. The outer surfaces of both sides of the protection cover 61 are slidably connected with clamping blocks 62. A protection mechanism 63 is fixedly installed on the inner wall of the protection cover 61. 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 when the optical fiber cable 3 is dragged, the protection mechanism 63 can offset the dragging force, that is, at this time, the protection cover 61 and the outer shell 1 are displaced, so that the alarm mechanism 64 emits an alarm to avoid the optical fibers 4 being separated from the connection due to continuous dragging. By pulling the protection covers 61 at both ends of the outer shell 1, the capping 2 is removed from the outer surface of the outer shell 1, which is convenient for maintaining the inside of the outer shell 1.,

[0044] Please refer to Figure 12 and Figure 14As shown, the protection mechanism 63 includes a fixing plate 631. The fixing plate 631 is fixedly connected to the protective cover 61.

A second clamping block 634 is fixedly connected to one end of the elastic rod 632. A fourth spring 635 is sleeved on the outer surface of the card hole 633. 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 engaged with the card hole 633. When connecting the fiber core 4, by pulling the elastic rod 632, the clamping block 62 is engaged with the card hole 633. At this time, the distance between the second clamping blocks 634 increases. The optical fiber cable 3 is passed through between the second clamping blocks 634. When the two fiber cores 4 are in close contact, the first clamping block 58 performs the first limit on the optical fiber cable 3. At this time, the clamping block 62 is moved so that the clamping block 62 and the card hole 633 are disengaged. Under the elastic force of the fourth spring 635, the second clamping block 634 clamps and fixes the optical fiber cable 3. When connecting the fiber core 4, a little more optical fiber cable 3 can be pre-stored between the protective cover 61 and the housing 1. In this way, when the optical fiber cable 3 is accidentally dragged, the optical fiber cable 3 in the inner cavity of the housing 1 will not be affected. Only the protective cover 61 and the housing 1 are driven to displace under the clamping of the protection mechanism 63. At this time, the alarm mechanism 64 issues an alarm to remind the user to pay attention to the strength and avoid the two fiber cores 4 from falling off.

[0045] Please refer to Figure 11 、 Figure 12 and Figure 13As shown in the figure, the alarm mechanism 64 includes a second connection block 641. A horn 642 is fixedly installed on the outer surface of the second connection block 641. A second button 643 is arranged on the outer surface of the second connection block 641. A slide bar 644 is fixedly installed on the outer surface of the second connection block 641. A fifth spring 645 is sleeved on the outer surface of the slide bar 644. A third fixing block 646 is fixedly installed on the outer surface of the protective cover 61. A second pressure rod 647 is slidably connected to the inner cavity of the third fixing block 646. The position adjustment of the second pressure rod 647 in the inner cavity of the third fixing block 646 is convenient for controlling the alarm distance. The second connection block 641 is fixedly connected to the housing 1. The second button 643 is electrically connected to the horn 642, and the pressing of the second button 643 controls the horn 642 to emit an alarm. The second pressure rod 647 is aligned with the second button 643. The slide bar 644 is slidably connected to the protective cover 61. The fifth spring 645 is located between the protective cover 61 and the second connection block 641. When the optical fiber cable 3 is pulled by an external force, since the protection mechanism 63 clamps and fixes the optical fiber cable 3, at this time, the pulling of the optical fiber cable 3 drives the protection mechanism 63 to move. The movement of the protection mechanism 63 drives the protective cover 61 to move on the housing 1. At this time, the optical fiber cable 3 pre-stored in the inner cavity of the protective cover 61 moves, and the optical fiber cable 3 in the inner cavity of the housing 1 is not affected. When the protective cover 61 moves, it drives the third fixing block 646 to move. The movement of the third fixing block 646 drives the second pressure rod 647 to move. The slide bar 644 moves in the inner cavity of the protective cover 61, and the second connection block 641 is fixed to the housing 1. At this time, the second pressure rod 647 squeezes the second button 643, causing the horn 642 to emit an alarm to remind the staff to pay attention. The optical fiber cable 3 is dragged under an external force, reminding the staff to stop dragging in time to avoid the core 4 from falling off. Under the elastic force of the fifth spring 645, the second connection 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 during dragging.

[0046] In summary, by fixing the optical fiber cable 3 in the inner cavity of the limiting component 5, the 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 cable 3, and the protection component 6 is used to prevent detachment. The cover 2 can be quickly disassembled on the housing 1 to facilitate the maintenance of the inside of the housing 1. The cover 2 can be made of a transparent material to facilitate observing the connection condition of the cores 4 inside the housing 1. When fixing the optical fiber cable 3, by pulling the insertion rod 572, the fixing ring 573 compresses the third spring 574. At this time, the insertion rod 572 and the insertion hole 575 are disengaged from the engagement. The optical fiber cable 3 is passed through the inner cavity of the limiting block 51, and the adjusting ring 54 is rotated to make the first clamping block 58 move on the convex strip 56, so that the first clamping block 58 is in close contact with the outer surface of the optical fiber cable 3. At this time, the insertion rod 572 is released, and under the elastic force of the third spring 574, the insertion rod 572 is engaged with the insertion hole 575 again, so that the adjusting ring 54 is stabilized in the inner cavity of the limiting block 51, and the first clamping block 58 limits the optical fiber cable 3. The support mechanism 52 is used to adjust the height of the limiting block 51, and the buffer mechanism 53 is used to flexibly limit the limiting block 51, so that the limiting block 51 can return to the far position when the housing 1 shakes, facilitating the cores 4 to always be in a connected state. By controlling the rotation of the adjusting ring 54, the first clamping block 58 can limit optical fiber cables 3 of different thicknesses, improving the overall fault tolerance of the device. The optical fiber cable 3 is secondarily limited by the protection mechanism 63 to ensure that the protection mechanism 63 can offset the pulling force when the optical fiber cable 3 is dragged. That is, at this time, the protective cover 61 and the housing 1 are displaced, and the alarm mechanism 64 issues an alarm to prevent the cores 4 from being disconnected due to continued dragging.
