[0001] The present invention belongs to the technical field of fiber optic array docking devices, and particularly relates to a fiber optic array docking device. Background Art

[0002] A fiber optic array is to install a single optical fiber, a bundle of optical fibers, or an optical fiber ribbon on an array substrate using a V-groove. The bare optical fiber part without the optical fiber coating is placed in the V-groove, pressed by a pressure member, and adhered by an adhesive. At the front end, the optical fiber is precisely positioned to be connected to a PLC. The joints of different optical fibers are installed on the array substrate. The fiber optic array is mainly used to directly transmit images. Numerous optical fibers arrange the end faces in a required geometric shape in a certain order to form a fiber optic array. The optical fiber arrangement positions at both ends of the array correspond one by one. One optical fiber in the array is equivalent to one pixel, and the optical image at one end of the fiber optic array will be reproduced at the other end.

[0003] The prior art CN222280895U discloses a fiber optic array docking device, including a docking seat, a round rod, and an optical fiber seat. A rectangular groove is provided at the upper end of the docking seat. A micro threaded rod is threadedly connected to the inner end of the docking seat, and a side rubber pad is fixedly installed at the inner end of the micro threaded rod. An upper rubber pad is fixedly installed at the lower end of the round rod, and a spring is fixedly installed at the upper end of the upper rubber pad. The spring is arranged outside the round rod. A pressing plate is rotatably installed at the upper end of the optical fiber seat, and silica gel pads are fixedly adhered to the inner ends of the pressing plate and the optical fiber seat. When the device is in use, the lifting block is lifted upward. The lifting block drives the round rod to move upward inside the support frame. The spring force is compressed, and the upper rubber pad moves upward. The fiber optic array to be docked is placed inside the rectangular groove provided in the docking seat. The micro threaded rod is rotated to push the side rubber pad inward to clamp and fix the joint of the fiber optic array. After both side rubber pads on both sides are tightened, the lifted lifting block is released. Under the pushing force of the spring, the round rod drives the upper rubber pad to move downward to the upper surface of the fiber optic array to press and limit the upper part of the fiber optic array. The operation is relatively cumbersome, reducing the efficiency of fiber optic docking. Summary of the Invention

[0030] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figures 1-9 An embodiment of the present invention provides an optical fiber array docking device, comprising a supporting seat 1, a fiber seat 2 is mounted on one side of the upper end of the supporting seat 1, a pressing plate 3 is screwed to one side of the upper end of the fiber seat 2, a silicone pad 4 is fixedly connected to the pressing plate 3 and the inner side of the fiber seat 2, and a fastener is mounted on the other side of the upper end of the supporting seat 1.

[0032] The fastener includes a housing A5, a housing B6, a housing C7, fastening shells 8 and a silica gel fastening strip 9. A pair of fastening shells 8 are mirror - installed. A cylinder 81 is installed on the upper wall surface of the fastening shell 8. The thin end 812 at the bottom of the cylinder 81 is movably installed in the groove 51 on the housing A5, and the thick end 811 at the top of the cylinder 81 is above the groove 51. The silica gel fastening strip 9 is embedded in the corresponding fastening shell 8. The housing B6 is screwed onto the upper wall surface of the housing A5. A pair of arched openings 62 are reserved in the center of the housing B6. An activity platform 61 is installed inside the arched openings 62. The distance between the center of the arched opening 62 and the center of the housing B6 is set to decrease in the positive direction. The thick end 811 at the top of the cylinder 81 is in the arched opening 62. Two sets of tooth openings 52 for embedding the activity platform 61 are reserved in the housing A5. The two sets of tooth openings 52 are circumferentially distributed. The housing C7 is installed on the top of the housing B6 and is used to fasten and loosen the housing A5 and the housing B6.

[0033] During use, pass the optical fiber body 11 through the arched opening on the base 12. The pair of fastening shells 8 in the loosened state are buckled on the base 12. Rotate the housing B6 clockwise. The arched opening 62 inside the housing B6 pulls the cylinder 81 to move in the groove 51 on the housing A5. The cylinder 81 drives the pair of fastening shells 8 at the bottom to move inward and approach the fastening base 12, so that it is firmly fastened on the base 12. During the movement of the cylinder 81, it drives the silica gel fastening strip 9 installed inside the fastening shell 8 to move inward. The silica gel fastening strip 9 presses the optical fiber body 11 to approach the base 12, and fastens the optical fiber body 11 in the arched opening on the base 12. Twist the housing C7 to make the housing B6 and the housing A5 approach each other, fasten the housing B6 on the housing A5, and restrict the rotation of the housing B6.

[0034] Under the loosening condition, the fastening shell 8 is buckled on the base 12, and the optical fiber body 11 passes through the arched opening on the base 12. The silica gel fastening strip 9 is located on the periphery of the optical fiber body 11. Rotating the housing B6 forwardly drives the cylinder 81 in the arched opening 62 to move. Since the distance between the center of the arched opening 62 and the center of the housing B6 decreases in the forward direction, the cylinder 81 moves towards the inside of the arched opening 62, and the cylinder 81 moves closer to the center in the groove 51 on the housing A5, so that the bottom fastening shell 8 fastens the base 12, and the inward movement of the fastening shell 8 causes the inner silica gel fastening strip 9 to press the optical fiber body 11 again, firmly fastening the optical fiber body 11 on the base 12; rotating the housing B6 causes the inner movable table 61 to be at the tooth opening 52 where it is separated in the center, unable to perform the engaging cooperation, preventing accidental fastening and inability to return, and enabling the fastening shell 8 to be fastened or released for a certain distance; when the housing B6 is rotated more than one-eighth of a turn, it becomes an action to prevent reverse movement. The head of the movable table 61 is inserted into the tooth opening 52 and cannot return to its original position. It can only be rotated forward continuously, which can prevent the housing B6 from loosening, achieving the purpose of preventing the reverse movement of the housing B6 and thus avoiding the loosening of the fastening shell 8. Then, twist the housing C7 to fasten the housing B6 on the housing A5 again. Through this fastener, the purpose of quickly fastening the optical fiber body 11 on the base 12 is achieved. It is not only very convenient to use, but also increases the contact area between the fastener and the optical fiber body 11, ensuring that the optical fiber body 11 is fastened more firmly.

[0035] Refer to Figure 4 And Figure 5 , two groups of tooth openings 52 and movable tables 61 are circumferentially and evenly arranged. The movable table 61 includes a deformation strip 611 and a constraint table 612. An avoidance opening 613 is reserved in the deformation strip 611. The constraint table 612 is fixedly connected to the head of the deformation strip 611. The constraint table 612 is inserted into the corresponding tooth opening 52. Consistent inclined guiding walls are reserved on both the constraint table 612 and the tooth opening 52. When fastening the fastening shell 8, during the forward rotation of the housing B6, the deformation strip 611 can be deformed. When the housing B6 is rotated more than one-eighth of a turn, the guiding wall of the constraint table 612 assists the guiding wall of the tooth opening 52. When the constraint table 612 can sequentially move into each tooth opening 52, the constraint table 612 can only move into another tooth opening 52 after rotating out. The deformation strip 611 restricts the rotation of the constraint table 612 within a certain range; after the constraint table 612 moves into the tooth opening 52 in the required area, to ensure the reliability of the connection, the purpose of preventing reverse movement and loosening is achieved.

[0036] Refer to Figure 4 And Figure 5, a circular opening 54 is reserved on the housing A5. The circular opening 54 is located above the groove 51, and a through groove 55 is reserved between the circular openings 54. A restraining platform two 63 that fits inside the circular opening 54 is installed inside the housing B6. The restraining platform two 63 on the housing B6 moves downward along the through groove 55 to the inside, enabling the housing B6 to move downward. Then, the restraining platform two 63 is rotated into the circular opening 54, which can ensure that the housing B6 rotates on the housing A5 in a certain area and cannot be separated.

[0037] Refer to Figure 5 and Figure 7 , the groove 51 is in a waist-shaped structure. The span between the two horizontal side walls of the groove 51 is smaller than the radial span of the thick end 811 at the top of the cylinder 81. The thin end 812 at the bottom of the cylinder 81 passes through the groove 51 and is embedded in the guiding opening 85 on the fastening shell 8. The thick end 811 and the thin end 812 are threadedly connected to each other. The groove 51 fits the cylindrical cylinder 81, which can allow the cylinder 81 to increase the distance along the movement of the groove 51 on the housing A5 in a specified area, thereby making the entire structure more ingenious; the cylinder 81 has an upper-wide and lower-narrow structure, and the bottom of the cylinder 81 is embedded in the fastening shell 8 to ensure that the fastening shell 8 can move and cannot be separated. The thick end 811 and the thin end 812 of the cylinder 81 are connected by a threaded connection for the disassembly and assembly of the cylinder 81.

[0038] Refer to Figure 6 and Figure 7 , two pairs of T-shaped moving platforms 53 are reserved at both sides of the lower end of the housing A5. The T-shaped moving platforms 53 are located on both sides of the groove 51. Two pairs of T-shaped channels 86 that fit the T-shaped moving platforms 53 are reserved on the upper wall surface of the fastening shell 8. The T-shaped moving platforms 53 and the T-shaped channels 86 are movably connected to ensure that the fastening shell 8 can move linearly, thereby enhancing the stability and adjustment accuracy during the operation of the entire structure. Moreover, the two pairs of T-shaped moving platforms 53 can enhance the stability of the movement of a pair of fastening shells 8.

[0039] Refer to Figure 7 and Figure 8 , a boss 82 is installed in the middle of the inner wall surface of the fastening shell 8. A pair of mirror-image embedding openings 83 are reserved on the inner wall surface of the fastening shell 8. The embedding openings 83 are located on both sides of the boss 82. A through opening 91 that fits the boss 82 is reserved in the middle of the convex surface of the silica gel fastening strip 9. Embedding columns 92 that fit the embedding openings 83 are installed on the convex surface of the silica gel fastening strip 9. The silica gel fastening strip 9 assists the boss 82 on the fastening shell 8 to perform embedding through the through opening 91, which can enable the silica gel fastening strip 9 to be assembled on the fastening shell 8; moreover, the two side embedding columns 92 cooperate to be embedded in the embedding openings 83 on the fastening shell 8, which can further enhance the stability of the assembly and can make the longitudinal two sides of the silica gel fastening strip 9 tilt downward due to its own weight to ensure the smoothness during the use of the fastener.

[0040] Refer to Figure 7 and Figure 8The fastening shell 8 is provided with an arched engagement opening 84 adapted to the upper end of the base 12 to ensure the fastening effect; the inner surface of the silicone fastening strip 9 is provided with an arched fastening opening 93 adapted to the surface of the optical fiber body 11, so that the area where the silicone fastening strip 9 and the optical fiber body 11 fit together is larger, thereby enhancing the fastening effect.

[0041] Reference Figure 3 A lead screw 71 is fixedly connected to the lower wall of the shell C7, and a nut 72 is installed on the lower wall of the shell A5. The lead screw 71 passes through the center of the shell B6 and the shell A5 and is threadedly connected to the nut 72 on the shell A5. By twisting the shell C7, the lead screw 71 is pulled to rotate, and the nut 72 moves toward the lead screw 71, and then the shell A5 and the shell B6 are fastened. The shell B6 cannot rotate on the shell A5, and then the bottom fastening shell 8 is fastened in advance.

[0042] The outer circumferences of the shell B6, shell C7 and the fastening shell 8 are all provided with inner grooves 10 to facilitate the user's operation during fastening.

[0043] Reference Figure 2 and Figure 9 An auxiliary disassembly unit is installed on the shell B6, and the auxiliary disassembly unit includes a T-slot 13 reserved on the upper wall of the shell B6 and vertically penetrating, the T-slot 13 corresponds to the avoidance opening 613, and a toggle bar 14 is movably installed in the T-slot 13, and the bottom of the toggle bar 14 is fixedly connected to the constraint platform 612.

[0044] When disassembling the optical fiber body 11, twist the shell C7 in the reverse direction to release the pressure on the shell B6, push the toggle bar 14 outward, move the constraint platform 612 away from the tooth mouth 52 and move toward the avoidance mouth 613, and then twist the shell B6 in the reverse direction to move the constraint platform 612 completely away from the tooth mouth 52. The cylinder 81 pulls the pair of fastening shells 8 at the bottom to move away and unlock the base 12. During the movement of the cylinder 81, the silicone fastening strip 9 installed in the fastening shell 8 is pulled outward, and the silicone fastening strip 9 releases the pressure on the optical fiber body 11. Therefore, the optical fiber body 11 can be disassembled, and it is very convenient to use.
