Description

Technical Field

[0001] This invention belongs to the technical field of fiber optic array docking devices, and specifically relates to a fiber optic array docking device. Background Technology

[0002] A fiber optic array uses V-grooves to mount a single optical fiber, a bundle of optical fibers, or a fiber ribbon onto an array substrate. The exposed fiber portion, after the fiber coating has been removed, is placed in the V-groove, pressurized by a pressurizing device, and bonded with adhesive. At the front end, the fiber is precisely positioned for connection to a PLC. The joints of different fibers are mounted on the array substrate. Fiber optic arrays are primarily used for direct image transmission. Numerous optical fibers are arranged in a specific order with their end faces forming a desired geometry, creating a fiber optic array. The fiber positions at both ends of the array correspond one-to-one; each fiber in the array represents a pixel, and the optical image at one end of the array is reproduced at the other end.

[0003] Existing technology CN222280895U discloses a fiber optic array docking device, comprising: a docking seat, a round rod, and a fiber optic base. The upper end of the docking seat has a rectangular groove, and the inner end of the docking seat is threaded with a miniature threaded rod. A side rubber pad is fixedly installed on the inner end of the miniature threaded rod. An upper rubber pad is fixedly installed on the lower end of the round rod, and a spring is fixedly installed on the upper end of the upper rubber pad. The spring is located on the outer side of the round rod. A pressure plate is rotatably installed on the upper end of the fiber optic base, and silicone pads are fixedly adhered to the inner ends of both the pressure plate and the fiber optic base. When using this device, the lifting block is pulled upwards, causing the round rod to move upwards inside the support frame. The spring force compresses the rod, and the upper rubber pad moves upwards. The fiber array to be connected is placed inside the rectangular slot in the connection seat. The micro threaded rod is rotated to push the side rubber pads inwards, clamping and fixing the fiber array connectors. After both side rubber pads are tightened, the lifting block is released. Under the spring force, the round rod moves the upper rubber pad downwards to the upper surface of the fiber array, pressing down and limiting the upper part of the fiber array. The operation is relatively cumbersome and reduces the efficiency of fiber connection. Summary of the Invention

[0004] This invention provides a fiber optic array docking device, which aims to solve the problem that existing fiber optic array docking devices are cumbersome to operate and reduce the efficiency of fiber optic docking.

[0005] This invention provides a fiber optic array docking device, including a carrier base, an optical fiber seat mounted on one side of the upper end of the carrier base, a pressure plate screwed onto one side of the upper end of the optical fiber seat, a silicone pad fixed to the inner side of the pressure plate and the optical fiber seat, and a fastener mounted on the other side of the upper end of the carrier base.

[0006] The fastener includes housing A, housing B, housing C, a fastening shell, and a silicone fastening strip. A pair of fastening shells are mirror-mounted. A cylinder is mounted on the upper wall of the fastening shell. The narrow end of the cylinder is movably mounted in a groove on housing A, while the thicker end of the cylinder is above the groove. The silicone fastening strip is embedded in the corresponding fastening shell. Housing B is screwed onto the upper wall of housing A. A pair of arched openings are pre-drilled in the center of housing B, and a movable platform is installed inside each arched opening. The distance between the center of the arched opening and the center of housing B decreases in the forward direction. The thicker end of the cylinder is located within the arched opening. Housing A has two sets of pre-drilled teeth for engaging the movable platform, distributed circumferentially. Housing C is mounted on top of housing B and is used to fasten and loosen housings A and B.

[0007] Furthermore, the toothed mouth and the movable table are evenly arranged in two sets in the circumferential direction. The movable table includes a deformation strip and a first constraint table. The deformation strip has a reserved avoidance opening. The first constraint table is fixed to the head of the deformation strip and is embedded in the corresponding toothed mouth. Both the first constraint table and the toothed mouth have reserved consistent skewed guide walls.

[0008] Furthermore, a ring-shaped opening is reserved on shell A, which is located above the groove. A through groove is reserved between the ring-shaped openings. A constraint platform 2 that fits into the ring-shaped opening is installed inside shell B.

[0009] Furthermore, the trench has a waist-shaped structure, the span between the two horizontal sidewalls of the trench is smaller than the radial span of the thick end at the top of the cylinder, the thin end at the bottom of the cylinder passes through the trench and is embedded in the guide hole on the fastening shell, and the thick end and the thin end are threaded together.

[0010] Furthermore, two pairs of T-shaped adjustable platforms are reserved on both sides of the lower end of the shell A. The T-shaped adjustable platforms are located on both sides of the trench, and two pairs of T-shaped channels adapted to the T-shaped adjustable platforms are reserved on the upper wall of the fastening shell.

[0011] Furthermore, a protrusion is installed in the center of the inner wall of the fastening shell, and a pair of mirror-shaped interfacings are reserved in the inner wall of the fastening shell. The interfacings are located on both sides of the protrusion. A through-hole adapted to the protrusion is reserved in the center of the convex surface of the silicone fastening strip, and an interfacing post adapted to the interfacing is installed on the convex surface of the silicone fastening strip.

[0012] Furthermore, the fastening shell has an arched engagement opening that matches the upper part of the base, and the inner surface of the silicone fastening strip has an arched fastening opening that matches the surface of the optical fiber body.

[0013] Furthermore, a lead screw is fixedly connected to the lower wall of housing C, and a lead nut is installed on the lower wall of housing A. The lead screw passes through the center of housing B and housing A and is threaded to the lead nut on housing A.

[0014] Furthermore, internal bevels are reserved on the outer circumferential surfaces of shells B, C, and the fastening shell.

[0015] Furthermore, an auxiliary disassembly unit is installed on the housing B. The auxiliary disassembly unit includes a T-shaped groove that is pre-reserved on the upper wall of the housing B and extends vertically through it. The T-shaped groove corresponds to the avoidance opening. A toggle bar is movably installed in the T-shaped groove, and the bottom of the toggle bar is fixedly connected to the constraint table.

[0016] The beneficial effects of this invention are as follows:

[0017] This invention involves twisting housing B, causing the arc-shaped opening inside housing B to pull the cylinder to move within the groove on housing A. This pulls the pair of bottom fastening shells inward toward the fastening base, and assists the moving silicone fastening strip to press the optical fiber body into the arched opening on the base, achieving rapid fastening of the optical fiber body for ease of use. Furthermore, the movable platform on housing B assists the teeth on housing A, ensuring that the bottom fastening shell can only move to one side, preventing the fastening shell from loosening and moving in the opposite direction. Twisting the housings to fasten housing B and housing A enhances stability and fastening effect during use. The initial rotation of the movable platform does not engage with the teeth to prevent unintentional fastening that cannot be reversed, allowing the fastening shells to fasten or loosen for a certain distance.

[0018] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-9 This invention provides a fiber optic array docking device, which includes a carrier 1, an optical fiber seat 2 mounted on one side of the upper end of the carrier 1, a pressure plate 3 screwed onto one side of the upper end of the optical fiber seat 2, a silicone pad 4 fixedly connected to the inner side of the pressure plate 3 and the optical fiber seat 2, and a fastener mounted on the other side of the upper end of the carrier 1.

[0032] The fastener includes housing A5, housing B6, housing C7, fastening shell 8, and silicone fastening strip 9. A pair of fastening shells 8 are mirror-mounted. A cylinder 81 is mounted on the upper wall of each fastening shell 8. The narrow end 812 of the cylinder 81 is movably mounted in a groove 51 on housing A5, and the thick end 811 of the cylinder 81 is above the groove 51. The silicone fastening strip 9 is embedded in the corresponding fastening shell 8. Housing B6 is screwed onto the upper wall of housing A5. A pair of arched openings 62 are reserved in the center of body B6. A movable platform 61 is installed inside the arched openings 62. The distance between the center of the arched openings 62 and the center of body B6 decreases in the positive direction. The thick end 811 of the top of the cylinder 81 is located in the arched openings 62. Two sets of teeth 52 are reserved in body A5 to fit the movable platform 61. The two sets of teeth 52 are circumferentially distributed. Body C7 is installed on the top of body B6 and is used to fasten and loosen body A5 and body B6.

[0033] In use, the optical fiber body 11 is passed through the arched opening on the base 12. In the loosened state, the pair of fastening shells 8 are fastened to the base 12. Rotating the shell B6 in the forward direction causes the arched opening 62 inside the shell B6 to pull the cylinder 81 to move in the groove 51 on the shell A5. The cylinder 81 also pulls the pair of fastening shells 8 at the bottom inward toward the fastening base 12, so that it is firmly fastened to the base 12. During the movement of the cylinder 81, the silicone fastening strip 9 installed inside the fastening shell 8 is pulled inward. The silicone fastening strip 9 presses the optical fiber body 11 toward the base 12, fastening the optical fiber body 11 to the arched opening on the base 12. Twisting the shell C7 brings the shell B6 and the shell A5 closer together, fastening the shell B6 to the shell A5 and restricting the rotation of the shell B6.

[0034] In the loosened state, the fastening shell 8 is fastened to the base 12, and the optical fiber body 11 passes through the arched opening on the base 12. The silicone fastening strip 9 is located around the optical fiber body 11. Rotating the shell B6 in the forward direction pulls the cylinder 81 in the arched opening 62 to move. Because the distance between the center of the arched opening 62 and the center of the shell B6 decreases in the forward direction, the cylinder 81 moves inward into the arched opening 62, and the cylinder 81 moves closer to the center in the groove 51 on the shell A5, causing the fastening shell 8 at the bottom to fasten the base 12. The inward movement of the fastening shell 8 causes the silicone fastening strip 9 inside to press against the optical fiber body 11 again, allowing... The fiber optic body 11 is securely fastened to the base 12. Rotating the housing B6 causes the internal movable stage 61 to engage at the centrally separated teeth 52, preventing accidental tightening and ensuring it can be released or tightened a short distance. When the housing B6 rotates more than one-eighth of a turn, it prevents reverse movement; the head of the movable stage 61 engages in the teeth 52 and cannot return to its original position, allowing only forward rotation. This prevents the housing B6 from loosening, thus preventing reverse movement and consequently, preventing the fastening shell 8 from loosening. Twisting the housing C7 then re-fastens the housing B6 to the housing A5. This fastener quickly and easily secures the fiber optic body 11 to the base 12, not only making it very convenient to use but also increasing the contact area between the fastener and the fiber optic body 11, ensuring a more secure fastening.

[0035] Reference Figure 4 and Figure 5 Two sets of teeth 52 and movable table 61 are evenly arranged in the circumferential direction. Movable table 61 includes deformable strip 611 and constraint table 612. Deformable strip 611 has a reserved avoidance opening 613. Constraint table 612 is fixed to the head of deformable strip 611 and is embedded in the corresponding teeth 52. Constraint table 612 and teeth 52 both have reserved consistent skewed guide walls. When fastening the fastening shell 8, during the forward rotation of the shell B6, the deformation strip 611 can deform. The shell B6 rotates more than one-eighth of a turn. The guide wall of the constraint platform 612 assists the guide wall of the tooth 52. When the constraint platform 612 can move into each tooth 52 in sequence, the constraint platform 612 can only move into another tooth 52 after it has rotated out. The deformation strip 611 restricts the rotation of the constraint platform 612 within a certain range. After the constraint platform 612 moves into the tooth 52 of the required area, it ensures the reliability of the connection and achieves the purpose of preventing loosening due to reverse movement.

[0036] Reference Figure 4 and Figure 5The housing A5 has a pre-drilled annular opening 54 located above the groove 51. A through groove 55 is pre-drilled between the annular openings 54. A second constraint platform 63, adapted to fit within the annular opening 54, is installed inside the housing B6. The second constraint platform 63 on the housing B6 moves downwards along the through groove 55, allowing the housing B6 to move downwards. Then, by rotating the second constraint platform 63 into the annular opening 54, it ensures that the housing B6 cannot separate from the housing A5 when rotated within a certain area.

[0037] Reference Figure 5 and Figure 7 The channel 51 has an waist-shaped structure. The span between the two horizontal sidewalls of the channel 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 channel 51 and is embedded in the guide port 85 on the fastening shell 8. The thick end 811 and the thin end 812 are threaded together. The channel 51 adapts to the cylindrical cylinder 81, allowing the cylinder 81 to expand its spacing on the shell A5 in a designated area along with the movement of the channel 51, thus making the entire structure more ingenious. The cylinder 81 adopts a structure that is wider at the top and narrower at the bottom, and the bottom of the cylinder 81 is embedded in the fastening shell 8, ensuring that the fastening shell 8 can move but cannot be separated. The thick end 811 and the thin end 812 of the cylinder 81 are connected by a threaded connection to facilitate the disassembly and assembly of the cylinder 81.

[0038] Reference Figure 6 and Figure 7 Two pairs of T-shaped adjustable platforms 53 are reserved on both sides of the lower end of the housing A5. The T-shaped adjustable platforms 53 are located on both sides of the trench 51. Two pairs of T-shaped channels 86 adapted to the T-shaped adjustable platforms 53 are reserved on the upper wall of the fastening housing 8. The T-shaped adjustable platforms 53 and the T-shaped channels 86 are movably connected to ensure that the fastening housing 8 can move linearly, thereby enhancing the stability and adjustment accuracy of the entire structure during use. In addition, the two pairs of T-shaped adjustable platforms 53 can enhance the stability of the movement of one pair of fastening housings 8.

[0039] Reference Figure 7 and Figure 8 A protrusion 82 is installed in the center of the inner wall of the fastening housing 8. A pair of mirror-shaped interlocking interfaces 83 are reserved on the inner wall of the fastening housing 8, located on both sides of the protrusion 82. A through-hole 91 adapted to the protrusion 82 is reserved in the center of the convex surface of the silicone fastening strip 9. An interlocking post 92 adapted to the interlocking interface 83 is installed on the convex surface of the silicone fastening strip 9. The silicone fastening strip 9 assists the protrusion 82 on the fastening housing 8 in interlocking through the through-hole 91, allowing the silicone fastening strip 9 to be assembled on the fastening housing 8. Furthermore, the interlocking posts 92 on both sides cooperate to interlock with the interlocking interfaces 83 on the fastening housing 8, which can further enhance the stability of the assembly. It also allows the longitudinal sides of the silicone fastening strip 9 to tilt downwards due to its own weight, ensuring the smoothness of the fastener during use.

[0040] Reference Figure 7 and Figure 8The fastening shell 8 has an arched engagement opening 84 that fits the upper end of the base 12 to ensure the fastening effect; the inner surface of the silicone fastening strip 9 has an arched fastening opening 93 that fits 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 fixed to the lower wall of housing C7, and a lead nut 72 is installed on the lower wall of housing A5. The lead screw 71 passes through the center of housing B6 and housing A5 and is threaded to the lead nut 72 on housing A5. By twisting housing C7, the lead screw 71 is pulled to rotate, causing the lead nut 72 to move onto the lead screw 71, thereby fastening housing A5 and housing B6. Housing B6 cannot rotate on housing A5, thus allowing the bottom fastening shell 8 to be pre-fastened.

[0042] The outer circumferential surfaces of housings B6, C7, and fastening housing 8 are all provided with internal loops 10 to facilitate the user's operation during fastening.

[0043] Reference Figure 2 and Figure 9 An auxiliary disassembly unit is installed on the housing B6. The auxiliary disassembly unit includes a T-shaped groove 13 that is pre-reserved on the upper wall of the housing B6 and extends vertically. The T-shaped groove 13 corresponds to the avoidance opening 613. A toggle bar 14 is movably installed in the T-shaped groove 13. The bottom of the toggle bar 14 is fixedly connected to the constraint platform 612.

[0044] When disassembling the optical fiber body 11, the housing C7 is twisted in the reverse direction to release the pressure on the housing B6. The actuating strip 14 is pushed outward to move the constraint platform 612 away from the tooth 52 and into the avoidance opening 613. Then, the housing B6 is twisted in the reverse direction to completely move the constraint platform 612 away from the tooth 52. The cylinder 81 pulls the pair of fastening shells 8 at the bottom to move away and release the base 12. During the movement of the cylinder 81, the silicone fastening strip 9 installed inside the fastening shell 8 is pulled outward. The silicone fastening strip 9 releases the pressure on the optical fiber body 11. Therefore, the optical fiber body 11 can be disassembled and used very conveniently.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
