Description

Technical Field

[0001] This invention relates to the field of communication technology, specifically to a fiber optic array positioning device and a fiber optic array docking device. Background Technology

[0002] Fiber optic arrays utilize V-grooves to mount a single optical fiber, a bundle of optical fibers, or a fiber ribbon onto an array substrate. Precisely etched V-grooves are essential for fiber optic array positioning. Multiple grooves are cut into the substrate, and the exposed portions of the optical fibers are precisely placed within these grooves. A pressure-pressurizing device is used to apply pressure, and the fibers are secured with adhesive. Finally, the end faces are optically polished to achieve the required precision. Through precise positioning using V-grooves, accurate positioning, stable fixation, and efficient coupling of the fiber optic array can be achieved, thereby improving the performance and reliability of the optical system. Currently, the primary use of fiber optic connectors is for splicing optical fibers, and they are widely used in fiber optic communication systems. During fiber splicing, fiber optic connectors precisely align the end faces of the transmitting and receiving fibers, maximizing the coupling of light energy from the transmitting fiber to the receiving fiber.

[0003] In the prior art, such as the fiber array positioning device disclosed in CN220252219U, a two-dimensional mechanical positioning of the fiber array is achieved by setting longitudinal and transverse stop surfaces on the substrate. This makes positioning more convenient and effective while ensuring optical performance.

[0004] However, in actual use, the base plate and cover plate used to fix the fiber optic array are often positioned by adhesive bonding. Over time, the adhesive is prone to aging, volatilization, or delamination, which leads to a decrease in the stability and optical performance of the fiber optic array. Furthermore, when the transmitting and receiving fibers are connected, there is a lack of reinforcement structure between them and the connector, which makes them prone to loosening during use, affecting performance and network transmission stability, and impacting transmission quality.

[0005] Therefore, this invention proposes a fiber optic array positioning device and a fiber optic array docking device to solve the problems of existing adhesive bonding between the substrate and the cover plate, where the adhesive is prone to aging, volatilization, or delamination after long-term use, resulting in the instability and optical performance of the fiber optic array, and the lack of reinforcement structure in the docking device affecting the transmission effect.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1, please refer to Figure 1-19The present invention provides a technical solution: a fiber optic array positioning device, comprising a fiber optic array positioning component 1, which consists of a positioning shell 11, a positioning shell 2 12, and a positioning shell 3 13. The positioning shell 2 12 and the positioning shell 3 13 are movably engaged. An optical fiber 10 is disposed between the positioning shell 2 12 and the positioning shell 3 13. A lens 100 is disposed at the front end of the optical fiber 10. An optical fiber connection protective sleeve 2 is disposed on the outer side of the end of the fiber optic array positioning component 1 away from the lens 100. The optical fiber connection protective sleeve 2 includes a rib 21, a pressing spring plate 22, and a touch crossbar 24. An optical fiber pressurizing component is disposed between the positioning shell 2 12 and the positioning shell 3 13. The optical fiber pressurizing component includes a pushing block 14. A pressing locking component is disposed on the outer side of the end of the positioning shell 2 12 and the positioning shell 3 13 near the optical fiber connection protective sleeve 2.

[0042] Example 2, see attached document Figure 1-19 Based on Embodiment 1, in order to achieve the positioning and installation of the optical fiber 10 by the positioning shell 2 12 and the positioning shell 3 13, and the dynamic compensation after the positioning of the optical fiber 10:

[0043] The lower end of positioning shell 2 12 is fixedly connected to the upper end of positioning shell 1 11. Adaptive arc grooves 120 are respectively opened on the sides of positioning shell 2 12. An annular convex groove plate 130 is correspondingly fixedly installed on the side of positioning shell 3 13. The outer surface of the annular convex groove plate 130 is adapted and embedded with the adaptive arc groove 120. A placement groove 1200 is opened at the end of positioning shell 2 12 near the fiber optic connection protective sleeve 2. A comb-shaped clamping plate 1300 is movably engaged on the inner surface of the placement groove 1200. A sliding groove 1301 is opened on the inner wall of the end of positioning shell 3 13 located at the comb-shaped clamping plate 1300. The outer surface of the pushing block 14 is movably connected to the inner surface of the sliding groove 1301. The fiber optic pressurization assembly also includes a fiber optic clamp 141 and a sliding column 142. The upper surface of the fiber optic clamp 141 is fixedly connected to the inner end of the pushing block 14. The fiber optic clamp 141 has sliding posts 142 fixedly installed at both ends. The outer surface of the sliding posts 142 is movably connected to the inner surface of the annular groove plate 130. The lower surface of the fiber optic clamp 141 is movably abutting against the upper surface of the fiber optic cable 10. An elastic abutting member is provided on one side of the fiber optic clamp 141. The elastic abutting member includes a connecting frame 1411, an abutting plate 1412, and a curved abutting piece 1413. The connecting frame 1411 is fixedly installed on one side of the fiber optic clamp 141. One end of the abutting plate 1412 is rotatably connected to the lower surface of the connecting frame 1411. The upper surface of the abutting plate 1412 is fixedly connected to one end of the curved abutting piece 1413, and the other end of the curved abutting piece 1413 is fixedly connected to the lower surface of the connecting frame 1411. The lower surface of the abutting plate 1412 is movably abutting against the upper surface of the fiber optic cable 10.

[0044] In this embodiment, before the fiber optic connection protective sleeve 2 covers the fiber optic array positioning component 1, the fiber 10 is inserted sequentially through the placement groove 1200, and the stripped section and the fixed section of the fiber 10 are placed in the corresponding positions. After being placed in the corresponding positions, the comb-shaped card plate 1300 of the positioning shell 13 is aligned with the placement groove 1200 for adaptation and insertion. At this time, the comb-shaped card plate 1300 can abut against the upper end of the fiber 10 and realize the docking and assembly of the positioning shell 2 12 and the positioning shell 3 13 to prevent displacement.

[0045] When the upper part of the optical fiber 10 is further clamped, one end of the pushing block 14 is manually pushed forward. At this time, the pushing block 14 and the optical fiber clamp 141 gradually move forward and downward under the limiting action of the annular groove plate 130 and the sliding column 142. When the sliding column 142 moves to the end position of the annular groove plate 130, the lower surface of the optical fiber clamp 141 abuts against the upper end of the optical fiber 10, and refers to 9- Figure 10 As shown, at this time, the elastic abutment connected to one side of the fiber clamp 141 provides auxiliary abutment to the surface of the fixed section of the fiber 10. Relying on the elastic deformation of the curved abutment piece 1413, it absorbs the assembly tolerance, prevents the fiber 10 from shifting, and achieves dynamic compensation for the fiber 10, further ensuring the stability of the fiber 10's positioning.

[0046] Example 3, refer to Appendix Figure 1-19 Based on Embodiment 2, in order to achieve locking of the optical fiber 10 after the push block 14 is displaced:

[0047] The press-lock assembly includes an edge protrusion 121 and a limiting vertical plate 131. The limiting vertical plate 131 is fixedly connected to the outer surface of the positioning shell 13. The inner wall of the limiting vertical plate 131 is provided with a locking groove 1310 and a side groove 1320. The edge protrusion 121 is fixedly installed on one side surface of the positioning shell 12. A V-shaped locking block 122 is movably installed at the upper end of the positioning shell 12. The cross-section of the V-shaped locking block 122 is V-shaped. The two ends of the V-shaped locking block 122 are respectively in contact with the inner surface of the locking groove 1310. The press-lock assembly also includes a limiting sleeve 124 and a sliding contact rod 125. A fixed back plate 123 is fixedly installed on one side of the limiting sleeve 124. The fixed back plate 123 is fixedly connected to the outer surface of the positioning housing 12 by bolts. The outer surface of the sliding contact rod 125 is slidably connected to the inner surface of the center of the limiting sleeve 124. The upper end of the sliding contact rod 125 is in movable contact with the lower surface of the push block 14. A limiting groove 1240 is formed on the inner wall of the outer ring of the limiting sleeve 124. The inner surface of the limiting groove 1240 is movably connected to... A limiting protrusion 1251 is fixedly installed on the outside of the sliding contact rod 125. A cam plate 127 is fixedly connected to the lower end of the sliding contact rod 125. A spring 126 is fixedly installed on the upper surface of the cam plate 127. A rotating seat is fixedly connected to the other end of the spring 126. The outer surface of the rotating seat is rotatably connected to the inner wall of the lower surface of the limiting sleeve 124, and the outer surface of the cam plate 127 is movably abutting against the inner surface of the V-shaped locking block 122. A pre-reserved groove is provided on the outer surface of the limiting sleeve 124. The slot is equipped with a locking mechanism, which includes a thumb contact plate 1400 and a central spring block 1401. The central spring block 1401 is fixedly installed in the center of the slot, and both ends of the central spring block 1401 are fixedly connected to one end of the thumb contact plate 1400. The other end of the thumb contact plate 1400 is movably inserted into the inner surface of the side groove 1320. Through the matching insertion of the thumb contact plate 1400 and the side groove 1320, the locking between the push block 14 and the limiting vertical plate 131 is realized, which also facilitates the operation of the operator's thumb.

[0048] In this embodiment, after the fiber optic clamp 141 is pressed against the surface of the fiber optic cable 10, the bottom of the end of the pushing block 14 away from the fiber optic clamp 141 presses against the top of the sliding contact rod 125. At this time, the limiting protrusion 1251 connected to one side of the sliding contact rod 125 moves inside the limiting groove 1240, so that the sliding contact rod 125 gradually descends during the pressing process by the bottom of the pushing block 14 above, causing the sliding contact rod 125 and the cam plate 127 connected to the lower end to rotate. At the same time, the spring 126 is stretched and deformed. Figure 8As shown, when the cam plate 127 swings, it supports the V-shaped locking blocks 122 on both sides. At this time, the V-shaped locking blocks 122 expand to both sides and lock with the locking groove 1310. This makes the positioning shell 3 13 and positioning shell 2 12 further locked after they are inserted. It is worth noting that the pushing block 14 passes through the docking groove 1201 and the sliding groove 1301 opened on the positioning shell 2 12. It can be used as a pressing and holding part of the optical fiber 10, and can also play a role in further interlocking the positioning shell 2 12 and positioning shell 3 13, further ensuring the stability and tightness of the assembly between the positioning shell 2 12 and positioning shell 3 13.

[0049] It should be noted that when the push block 14 is moving forward, the operator pinches the thumb touch plates 1400 on both sides of the push block 14 with two fingers. The thumb touch plates 1400 are subjected to force, and under the action of force, the central spring block 1401 is compressed by the pressure from both sides. When the push block 14 reaches the final locked position, the two fingers are released. At this time, the reverse elastic force of the central spring block 1401 pushes the thumb touch plates 1400 to move to both sides respectively. The thumb touch plates 1400 are inserted into the side groove 1320 to achieve locking. At this time, the push block 14 will not bounce up under the action of external force, thus achieving multiple locking.

[0050] Example 4, see attached document Figure 1-19 Based on Embodiment 3, in order to achieve enhanced protection for the modular fiber array positioning component 1 and the assembled fiber 10:

[0051] The protruding ribs 21 are fixedly installed on both sides of the fiber optic connection protective sleeve 2 and are integrally formed with the fiber optic connection protective sleeve 2. One end of the outer surface of the fiber optic connection protective sleeve 2 is fixedly connected to one end of the pressing spring plate 22. An elastic abutment 23 is fixedly connected to the inner surface of the pressing spring plate 22. The other end of the elastic abutment 23 is fixedly connected to the outer surface of the fiber optic connection protective sleeve 2. The actuating crossbar 24 is fixedly installed at the end of the pressing spring plate 22 away from the connection between the fiber optic connection protective sleeve 2 and the protruding ribs 21. A locking hole 210 is opened on the inner wall of the protruding ribs 21. A through hole 2100 is provided on one side of the through hole 2100. An expansion groove is provided at the end of the through hole 2100 away from the lock hole 210. The diameter of the expansion groove is larger than the diameter of the through hole 2100. An abutment rod 2101 is slidably connected to the inner surface of the through hole 2100. A contact is fixedly installed at the end of the abutment rod 2101 away from the lock hole 210. A second spring 2102 is fixedly connected to the inner side of the contact. The other end of the second spring 2102 is fixedly connected to the inner wall of the expansion groove. The outer surface of the contact is in movable contact with the inner surface of the abutment crossbar 24.

[0052] In this embodiment, the connection end between the fiber array positioning component 1 and the fiber 10 is covered by the fiber connection protective sleeve 2. The ribs 21 added to the outside of the fiber connection protective sleeve 2 can increase the friction when holding the device and enhance the overall structural strength of the fiber connection protective sleeve 2.

[0053] Example 5, see attached document Figure 1-19 Based on Embodiment 4, the present invention also provides a fiber optic array docking device, including a network connector 3. The network connector 3 contains the aforementioned fiber optic array positioning device. A connection port is provided at the front end of the network connector 3, and a fiber optic connector 6 is provided inside the connection port. A transmitting fiber optic socket 4 and a receiving fiber optic socket 5 are respectively provided at both ends of the fiber optic connector 6. The transmitting fiber optic socket 4 and the receiving fiber optic socket 5 have the same structure. The inner surfaces of the transmitting fiber optic socket 4 and the receiving fiber optic socket 5 are respectively provided with insertion holes 50. The inner surfaces of the insertion holes 50 are movably connected to the outer surface of the fiber optic array positioning component 1. The transmitting fiber optic socket 4 and the receiving fiber optic socket 5 are relatively far away from the insertion holes. A push-locking assembly is provided on one side of 50. The push-locking assembly includes a compensation block 51. A connecting ear plate 511 is fixedly installed at the lower end of the compensation block 51. A shaft is rotatably connected to the inner surface of the connecting ear plate 511. A swing plate 512 is fixedly installed on the outer surface of the shaft. An abutting spring block 2 513 is fixedly connected to the upper surface of the swing plate 512. The other end of the abutting spring block 2 513 is connected to the inner surface of the compensation block 51. A hook plate is provided at the end of the swing plate 512 away from the abutting spring block 2 513. The outer surface of the hook plate is in movable contact with the inner surface of the lock hole 210. The outer side of the hook plate is set as an inclined surface. The outer surface of the inclined surface is in movable contact with the end of the abutting rod 2101 away from the contact.

[0054] In this embodiment, refer to Figures 16-17 As shown, when the transmitting fiber optic group and the receiving fiber optic group are docked, since the transmitting fiber optic socket 4 and the receiving fiber optic socket 5 have the same structure, taking the receiving fiber optic socket 5 as an example, when the pressing spring plates 22 on both sides of the handheld fiber optic connection protective sleeve 2 are inserted into the inside of the receiving fiber optic socket 5, the swing plate 512 on the inside of the compensation block 51 gradually contacts one end of the inner side of the protruding rib 21. As it continues to push inward, the abutting spring block 2 513 is squeezed, and the swing plate 512 swings. At this time, the swing plate 512... The hook plate at the end away from the abutting spring 513 is locked inside the lock hole 210. After the fiber array positioning component 1 and the fiber connector 6 are tightly inserted, the pressing spring plate 22 is released. When the hook plate is unlocked, the pressing spring plate 22 is pressed again. At this time, the pressing spring plate 22 deforms, which triggers the crossbar 24 to move inward and triggers the second spring 2102 to move inward. One end of the second spring 2102 holds the inclined surface of the hook plate, causing the hook plate to disengage from the lock hole 210, thus achieving automatic unlocking.

[0055] The working principle and usage process of this invention are as follows: In actual use, firstly, before the fiber optic connection protective sleeve 2 covers the fiber optic array positioning component 1, the fiber optic cable 10 is inserted sequentially through the placement groove 1200. The stripped section and the fixed section of the fiber optic cable 10 are placed in the corresponding positions. After being placed in the corresponding positions, the comb-shaped clamping plate 1300 of the positioning shell 3 13 is aligned with the placement groove 1200 for adaptation and insertion. At this time, the comb-shaped clamping plate 1300 can abut against the upper end of the fiber optic cable 10 and realize the docking and assembly of the positioning shell 2 12 and the positioning shell 3 13 to prevent displacement. When the upper position of the fiber optic cable 10 is further clamped, one end of the pushing block 14 is manually pushed forward. At this time, the pushing block 14 and the fiber optic clamp 141 are in the annular convex groove. Under the limiting action of plate 130 and sliding column 142, it gradually moves forward and downward. When sliding column 142 moves to the end position of annular convex plate 130, the lower surface of fiber optic clamp 141 abuts against the upper end of fiber optic 10. Then, after fiber optic clamp 141 presses against the surface of fiber optic 10, the bottom of the end of pushing block 14 away from fiber optic clamp 141 presses against the top of sliding contact rod 125. At this time, the limiting convex column 1251 connected to one side of sliding contact rod 125 moves inside the limiting groove 1240. This causes sliding contact rod 125 to gradually descend during the pressing process of the bottom of pushing block 14 above, causing sliding contact rod 125 and cam plate 127 connected to the lower end to rotate. At the same time, spring 126 is stretched. When the cam plate 127 swings, it supports the V-shaped locking blocks 122 on both sides. At this time, the V-shaped locking blocks 122 expand to both sides and lock with the locking groove 1310, thus further locking the positioning shell 3 13 and positioning shell 2 12 after they are inserted. Furthermore, when the push block 14 moves forward, the operator pinches the thumb contact plates 1400 on both sides of the push block 14 with two fingers. The thumb contact plates 1400 are subjected to force, and under the action of force, the central spring block 1401 is compressed by the pressure from both sides. When the push block 14 reaches the final locked position, the two fingers are released. At this time, the reverse elastic force of the central spring block 1401 pushes the thumb contact plates 1400 to move to both sides. When the thumb touch plate 1400 is inserted into the side groove 1320, it is locked. At this time, the push block 14 will not spring up under the action of external force, thus achieving multiple locking. Finally, when the transmitting fiber group and the receiving fiber group are docked, when the pressing spring plates 22 on both sides of the handheld fiber connection protective sleeve 2 are inserted into the receiving fiber socket 5, the swing plate 512 on the inner side of the compensation block 51 gradually contacts one end of the inner side of the protrusion rib 21. When it continues to push inward, the abutting spring block 2 513 is squeezed, the swing plate 512 swings, and at this time, the hook plate of the swing plate 512 away from the abutting spring block 2 513 is inserted into the lock hole 210 to form a lock. After the fiber array positioning component 1 and the fiber connector 6 are tightly inserted, the pressing spring plate 22 is released.When unlocking the hook plate, press the spring plate 22 again. The spring plate 22 deforms, causing the crossbar 24 to move inward, which in turn moves the second spring 2102 inward. One end of the second spring 2102 holds the inclined surface of the hook plate, causing the hook plate to disengage from the lock hole 210, thus achieving automatic unlocking.
