Description

Technical Field

[0001] The present invention relates to the field of communication technology, in particular to an optical fiber array positioning device and an optical fiber array docking device. Background Art

[0002] A fiber optic array utilizes a V-groove to mount an optical fiber, a bundle of optical fibers, or an optical fiber ribbon on an array substrate. Precision-engraved V-grooves are essential for positioning the fiber array. Multiple grooves are cut on the substrate, and the exposed portion of the optical fiber is precisely placed in the V-groove. The pressurized component is used to apply pressure, and the optical fiber is fixed with adhesive. Finally, the end face is optically polished to achieve the required accuracy. The precise positioning of the V-groove enables precise positioning, stable fixation, and efficient coupling of the fiber array, thereby improving the performance and reliability of the optical system. Currently, the main purpose of fiber optic connectors is to achieve optical fiber splicing, and they are widely used in optical fiber communication systems. When splicing optical fibers, the fiber optic connector can precisely connect the end faces of the transmitting optical fiber and the receiving optical fiber, thereby maximizing the coupling of the light energy output by the transmitting optical fiber to the receiving optical fiber.

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

[0004] However, in actual use, the base plate and cover plate used to fix the optical fiber array are mostly glued to position the optical fiber array. The glue is prone to aging, volatilization or debonding after long-term use, resulting in a decrease in the stability and optical performance of the optical fiber array; and when the transmitting optical fiber and the receiving optical fiber are docked, there is a lack of a reinforcement structure between the connector, which makes it easy to loosen during use, affecting the performance and stability of network transmission, and affecting the transmission effect.

[0005] Therefore, the present invention proposes an optical fiber array positioning device and an optical fiber array docking device to solve the problem that the existing substrate and cover plate are bonded together using glue, and the glue is prone to aging, volatilization or debonding after long-term use, resulting in the stability and optical performance of the optical fiber array and the lack of a reinforcement structure in the docking device affecting the transmission effect.

[0042] Example 2, refer to the attached Figure 1-19 On the basis of the first embodiment, in order to realize the positioning installation of the optical fiber 10 by the second positioning shell 12 and the third positioning shell 13 and the dynamic compensation after the optical fiber 10 is positioned:

[0043] The lower end of the positioning shell 2 12 is fixedly connected to the upper end of the positioning shell 1 1, and the sides of the positioning shell 2 12 are respectively provided with an adapting arc groove 120, and the sides of the positioning shell 3 13 are fixedly installed with an annular convex groove plate 130, and the outer surface of the annular convex groove plate 130 is adapted to be embedded in the adapting arc groove 120. The positioning shell 2 12 is provided with a placement groove 1200 at one end close to the optical fiber connection protective cover 2, and the inner surface of the placement groove 1200 is movably connected with a comb-shaped card plate 1300. The positioning shell 3 13 is provided with a slide groove 1301 on the inner wall of one end of the comb-shaped card plate 1300, and the outer surface of the push block 14 is movably connected to the inner surface of the slide groove 1301; the optical fiber pressurizing assembly also includes an optical fiber clamp 141 and a slide column 142, and the upper surface of the optical fiber clamp 141 is fixedly connected to the inner end of the push block 14, Slide columns 142 are fixedly installed at both ends of the optical fiber clamp 141, and the outer surface of the slide column 142 is movably connected to the inner surface of the annular convex groove plate 130, and the lower surface of the optical fiber clamp 141 is movably abutted against the upper surface of the optical fiber 10; an elastic abutment is provided on one side of the optical fiber clamp 141, and the elastic abutment includes a connecting frame 1411, a contact plate 1412 and a curved abutment 1413, the connecting frame 1411 is fixedly installed on one side of the optical fiber clamp 141, one end of the contact plate 1412 is rotatably connected to the lower surface of the connecting frame 1411, the upper surface of the contact plate 1412 is fixedly connected to one end of the curved abutment 1413, and the other end of the curved abutment 1413 is fixedly connected to the lower surface of the connecting frame 1411, and the lower surface of the contact plate 1412 is movably abutted against the upper surface of the optical fiber 10;

[0044] In this embodiment, before the optical fiber connection protective cover 2 covers the optical fiber array positioning assembly 1, the optical fibers 10 are sequentially inserted through the placement grooves 1200, and the stripped sections and the consolidation sections of the optical fibers 10 are placed in corresponding positions. After the corresponding placements are made, the comb-shaped card plate 1300 of the positioning shell 3 13 is aligned with the placement grooves 1200 for adaptation and plugging. At this time, the comb-shaped card plate 1300 can abut against the upper end of the optical 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 position of the optical fiber 10 is further clamped, one end of the push block 14 is manually pushed forward. At this time, the push block 14 and the optical fiber clamp 141 gradually move forward and downward under the limiting action of the annular convex groove plate 130 and the slide post 142. When the slide post 142 moves to the terminal position of the annular convex groove plate 130, the lower surface of the optical fiber clamp 141 contacts the upper end of the optical fiber 10, and with reference to 9- Figure 10 As shown, at this time, the elastic abutment connected to one side of the optical fiber clamp 141 assists in abutting the surface of the consolidated section of the optical fiber 10, and relies on the elastic deformation of the curved abutment piece 1413 to absorb assembly tolerances, prevent the optical fiber 10 from being displaced, and realize dynamic compensation of the optical fiber 10, further ensuring the stability of the positioning of the optical fiber 10.

[0046] Example 3, refer to the attached Figure 1-19 On the basis of the second embodiment, in order to achieve the locking of the optical fiber 10 after the pushing block 14 is moved:

[0047] The press-lock assembly includes an edge ridge 121 and a limiting vertical plate 131. The limiting vertical plate 131 is fixedly connected to the outer surface of the positioning shell three 13. The inner wall of the limiting vertical plate 131 is respectively provided with a locking groove 1310 and a side groove 1320. The edge ridge 121 is fixedly installed on one side surface of the positioning shell two 12. A V-shaped locking block 122 is movably installed on the upper end of the positioning shell two 12. The cross-section of the V-shaped locking block 122 is a "V"-shaped structure. The two ends of the V-shaped locking block 122 are respectively movably abutted against 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 shell 12 by bolts. The outer surface of the sliding contact rod 125 is slidably connected to the central inner surface of the limiting sleeve 124. The upper end of the sliding contact rod 125 is movably abutted against the lower surface of the push block 14. A limiting groove 1240 is provided 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 the inner surface of the limiting groove 1240. The limiting boss 1251 is fixedly mounted on the outside of the sliding contact rod 125. The lower end of the sliding contact rod 125 is fixedly connected to a cam plate 127. A spring 126 is fixedly mounted on the upper surface of the cam plate 127. The other end of the spring 126 is fixedly connected to a rotating seat. 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 abutted against the inner surface of the V-shaped lock block 122. The outer surface of the limiting sleeve 124 is provided with a reserved groove. A locking member is provided inside the reserved groove. The locking member includes a thumb touch plate 1400 and a central spring block 1401. The central spring block 1401 is fixedly mounted in the center of the reserved groove. The two ends of the central spring block 1401 are respectively fixedly connected to one end of the thumb touch plate 1400, and the other end of the thumb touch plate 1400 is respectively movably plugged into the inner surface of the side groove 1320. The adaptive plug-in connection between the thumb touch plate 1400 and the side groove 1320 realizes the locking between the push block 14 and the limit vertical plate 131, and facilitates the operator's thumb operation.

[0048] In this embodiment, when the optical fiber clamp 141 is pressed against the surface of the optical fiber 10, the bottom of the end of the push block 14 away from the optical fiber clamp 141 presses 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 process of being pressed by the bottom of the upper push block 14, 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 grooves 1310, so that the positioning shell 3 13 and the positioning shell 2 12 are further locked after being inserted. It is worth noting that the push block 14 passes through the docking groove 1201 and the sliding groove 1301 provided on the positioning shell 2 12, which can not only serve as a pressing and holding member for the optical fiber 10, but also play a role in further staggered insertion of the positioning shell 2 12 and the positioning shell 3 13, further ensuring the stability and tightness of the assembly between the positioning shell 2 12 and the 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, and the thumb touch plates 1400 are subjected to force. Under the action of the force, the center spring block 1401 is squeezed on both sides and compressed. When the push block 14 reaches the final locking position, the two fingers are released. At this time, the reverse elastic force of the center spring block 1401 pushes the thumb touch plates 1400 to move to both sides respectively, and 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 upward under the action of external force, thereby achieving multiple locking.

[0050] Example 4, refer to the attached Figure 1-19 On the basis of the third embodiment, in order to achieve enhanced protection of the modular optical fiber array positioning component 1 and the optical fiber 10 after assembly:

[0051] The convex rib 21 is fixedly mounted on both sides of the optical fiber connection protective sleeve 2 and is integrally formed with the optical fiber connection protective sleeve 2. One end of the outer surface of the optical fiber connection protective sleeve 2 is fixedly connected to one end of the pressing spring plate 22. The inner surface of the pressing spring plate 22 is fixedly connected with an elastic block 23. The other end of the elastic block 23 is fixedly connected to the outer surface of the optical fiber connection protective sleeve 2. The trigger cross bar 24 is fixedly mounted on the pressing spring plate 22 away from the connection end of the optical fiber connection protective sleeve 2 and the convex rib 21. A lock hole 210 is opened on the inner wall of the convex rib 21. The lock hole 210 A through hole 2100 is formed through one side of the through hole 2100, and an expansion groove is formed at the end of the through hole 2100 away from the lock hole 210. The groove body diameter of the expansion groove is larger than the groove body diameter of the through hole 2100. A resistance rod 2101 is slidably connected to the inner surface of the through hole 2100. A contact is fixedly installed at the end of the resistance 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, and the outer surface of the contact is movably abutted against the inner surface of the trigger cross bar 24.

[0052] In this embodiment, the connection end between the optical fiber array positioning assembly 1 and the optical fiber 10 is covered by the optical fiber connection protective cover 2. The ribs 21 added to the outside of the optical fiber connection protective cover 2 can not only increase the friction when holding, but also enhance the overall structural strength of the optical fiber connection protective cover 2.

[0053] Example 5, refer to the attached Figure 1-19 On the basis of the fourth embodiment, the present invention further provides a fiber array docking device, including a network connector 3, the interior of the network connector 3 includes the above-mentioned fiber array positioning device, the front end of the network connector 3 is provided with a connection port, the inner side of the connection port is provided with a fiber optic connector 6, and the two ends of the fiber optic connector 6 are respectively provided with a transmitting fiber optic socket 4 and a receiving fiber optic socket 5, the transmitting fiber optic socket 4 and the receiving fiber optic socket 5 have the same structure, the inner side surfaces of the transmitting fiber optic socket 4 and the receiving fiber optic socket 5 are respectively provided with a socket 50, the inner surface of the socket 50 is movably plugged into the outer surface of the fiber array positioning component 1, and the transmitting fiber optic socket 4 and the receiving fiber optic socket 5 are relatively far away from the socket A push-locking assembly is provided on one side of 50, and the push-locking assembly includes a compensation block 51; a connecting ear plate 511 is fixedly installed on the lower end of the compensation block 51, and the inner surface of the connecting ear plate 511 is rotatably connected to the shaft, and a swing plate 512 is fixedly installed on the outer surface of the shaft, and the upper surface of the swing plate 512 is fixedly connected to the second abutting spring block 513, and the other end of the second abutting spring block 513 is connected to the inner surface of the compensation block 51, and a hook plate is provided on the end of the swing plate 512 away from the second abutting spring block 513; the outer surface of the hook plate is movably abutted against the inner surface of the lock hole 210, and the outer side of the hook plate is provided with an inclined surface, and the outer surface of the inclined surface is movably abutted against the end of the abutting rod 2101 away from the contact;

[0054] In this embodiment, referring to Figure 16-17 As shown, when the transmitting optical fiber group and the receiving optical fiber group are connected, since the structures of the transmitting optical fiber socket 4 and the receiving optical fiber socket 5 are the same, the receiving optical fiber socket 5 is taken as an example below. When the pressing spring plates 22 on both sides of the holding optical fiber connection protective cover 2 are inserted into the inner side of the receiving optical fiber socket 5, the swing plate 512 on the inner side of the compensation block 51 gradually contacts the inner end of the rib 21. When it continues to push inward, the abutting spring block 2 513 is squeezed, and the swing plate 512 swings, and at this time the swing plate 512 The hook plate away from one end of the abutment spring block 213 is inserted into the inside of the lock hole 210 to form a lock. After the optical fiber array positioning assembly 1 and the optical fiber connector 6 are tightly plugged in, the pressing spring plate 22 is released; and when the hook plate is unlocked, the pressing spring plate 22 is held again. At this time, the pressing spring plate 22 is deformed, triggering the cross bar 24 to move inward, and the abutment spring 2102 to move inward. One end of the spring 2102 abuts against the inclined surface of the hook plate, causing the hook plate to slip out of the lock hole 210, thereby achieving automatic unlocking.

[0055] The working principle and usage process of the present invention: In actual use, first, before the optical fiber connection protective cover 2 covers the optical fiber array positioning component 1, the optical fiber 10 is inserted through the placement groove 1200 in sequence, and the stripped section and the consolidated section of the optical fiber 10 are placed in the corresponding positions. After the corresponding placement in sequence, the comb-shaped card plate 1300 of the positioning shell three 13 is aligned with the placement groove 1200 for adaptation and plugging. At this time, the comb-shaped card plate 1300 can both abut the upper end of the optical fiber 10 and realize the docking and assembly of the positioning shell two 12 and the positioning shell three 13 to prevent displacement. When the upper position of the optical fiber 10 is further clamped, one end of the pushing block 14 is manually pushed. At this time, the pushing block 14 and the optical fiber clamp 141 are in the annular convex groove Under the limiting action of the plate 130 and the sliding post 142, it gradually moves forward and downward. When the sliding post 142 moves to the terminal position of the annular convex groove plate 130, the lower surface of the optical fiber clamp 141 contacts the upper end of the optical fiber 10. Then, when the optical fiber clamp 141 is pressed tightly against the surface of the optical fiber 10, the bottom of the end of the pushing block 14 away from the optical fiber clamp 141 presses 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 in the process of being pressed by the bottom of the upper pushing block 14, 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 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 grooves 1310, so that the positioning shell 3 13 and the positioning shell 2 12 are further locked after being inserted; further, when the pushing block 14 is pushed forward, the operator pinches the thumb touch plates 1400 on both sides of the pushing block 14 with two fingers, and the thumb touch plates 1400 are subjected to force. Under the action of the force, the center spring block 1401 is squeezed and compressed on both sides. When the pushing block 14 reaches the final locking position, the two fingers are released. At this time, the reverse elastic force of the center spring block 1401 pushes the thumb touch plates 1400 to move to both sides. The thumb touch plate 1400 is inserted into the side groove 1320 to achieve locking. At this time, the push block 14 will not bounce upward under the action of external force, achieving multiple locking; finally, when the transmitting optical fiber group and the receiving optical fiber group are docked, the pressing spring plates 22 on both sides of the handheld optical fiber connection protective cover 2 are inserted into the inner side of the receiving optical fiber socket 5, and the swing plate 512 on the inner side of the compensation block 51 gradually contacts the inner end of the rib 21. When it is continuously pushed inward, the abutting spring block 513 is squeezed, and the swing plate 512 swings. At this time, the hook plate of the swing plate 512 away from the end of the abutting spring block 513 is locked into the inside of the lock hole 210 to form a lock. After the optical fiber array positioning assembly 1 and the optical fiber connector 6 are tightly plugged, the pressing spring plate 22 is released;To unlock the hook plate, the user presses the spring plate 22 again. This causes the spring plate 22 to deform, triggering the crossbar 24 to move inward, which in turn causes the second spring 2102 to move inward. One end of the second spring 2102 presses against the inclined surface of the hook plate, causing the hook plate to disengage from the lock hole 210, thus achieving automatic unlocking.
