Description

Technical Field

[0001] This utility model relates to the field of docking device technology, and in particular to a fiber optic array docking device. Background Technology

[0002] A fiber optic array is an array formed by mounting a bundle of optical fibers or a fiber ribbon at specified intervals on a V-groove substrate. The fabrication process involves placing the bare fiber portion (with the fiber coating removed) into the V-groove, pressurizing it with a pressurizing device, bonding it with adhesive, and finally grinding and polishing the surface to the required precision. At the front end, the fiber is precisely positioned for connection to a PLC.

[0003] Utility model patent 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 a miniature threaded rod is threaded to the inner end of the docking seat. 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, with the spring positioned on the outer side of the round rod. A pressure plate is rotatably mounted on the upper end of the fiber optic base. Silicone pads are fixedly adhered to the inner ends of both the pressure plate and the fiber optic base. A base is fixedly installed on the lower end of the docking seat, and a support frame is fixedly installed on the upper end of the base. This fiber optic array docking device facilitates the limited installation of fiber optic arrays of different sizes and specifications, can press down and limit the fiber optic array to prevent displacement during docking operations, facilitates the organization and limiting of fiber optic cables to prevent scattering, and improves the convenience of docking.

[0004] After searching, it was found that the existing technology has certain drawbacks. The device requires two devices to be used together when docking fiber arrays. Since the two docking devices are independent of each other, it is easy to cause longitudinal deviation between two fiber arrays of the same specification. Therefore, a fiber array docking device is needed to meet people's needs. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-8 A fiber optic array docking device includes a base 1, a bidirectional screw 2 rotatably connected to the base 1, a first knob 3 provided at one end of the bidirectional screw 2, a first docking seat 4 threadedly connected to the positive thread section of the bidirectional screw 2, and a second docking seat 5 threadedly connected to the negative thread section of the bidirectional screw 2. The first docking seat 4 and the second docking seat 5 are of the same specifications and symmetrical to each other, and both are rotatably connected to a first unidirectional screw 6. Each first unidirectional screw 6 is threadedly connected to a clamping plate 7. The two clamping plates 7 are slidably connected to the same position in the first docking seat 4 and the second docking seat 5, respectively. A square shaft 8 is rotatably connected to the base 1, a second knob 9 provided at one end of the square shaft 8, and two first helical gears 10 slidably connected to the square shaft 8. The two first helical gears 10 are in the same direction, and each of the two first helical gears 10 is meshed with a second helical gear 11. The two second helical gears 11 are respectively connected to the two first unidirectional screws 6.

[0027] Two identical fiber optic arrays are placed on the first docking seat 4 and the second docking seat 5 respectively. Rotating the second knob 9 causes the square shaft 8 to rotate, which in turn drives the two first helical gears 10 to rotate synchronously in the same direction. This causes the two second helical gears 11 on the first docking seat 4 and the second docking seat 5 to rotate synchronously in the same direction. Consequently, the two first unidirectional screws 6 on the first docking seat 4 and the second docking seat 5 rotate synchronously in the same direction. This allows the two clamping plates 7 to apply the same clamping force to the two fiber optic arrays, ensuring longitudinal alignment after the two fiber optic arrays are fixed on the first docking seat 4 and the second docking seat 5. Rotating the bidirectional screw 2 using the first knob 3 causes the first docking seat 4 and the second docking seat 5 to move synchronously relative to each other, allowing the two fiber optic arrays fixed on the first docking seat 4 and the second docking seat 5 to move horizontally, thus achieving docking. The sliding effect of the first helical gears 10 on the square shaft 8 ensures smooth relative movement of the first docking seat 4 and the second docking seat 5.

[0028] Specifically, in this embodiment, the base 1 is provided with two first guide rods 12, both of which are parallel to the bidirectional screw 2. The first docking seat 4 and the second docking seat 5 are slidably connected to the two first guide rods 12, and the first guide rods 12 provide stable horizontal movement guidance for the first docking seat 4 and the second docking seat 5.

[0029] Specifically, in this embodiment, square holes 13 are provided on both first helical gears 10, and square shaft 8 is adapted to fit in the square holes 13. This helps the first docking seat 4 and the second docking seat 5 to move relative to each other, thereby driving the two first helical gears 10 to produce the same movement effect. It also achieves the effect of the square shaft 8 driving the two first helical gears 10 to rotate synchronously and in the same direction.

[0030] Specifically, in this embodiment, a limiting block 14 is provided on the same side of the first docking seat 4 and the second docking seat 5. The limiting block 14 is arranged on the side of the first helical gear 10 away from the second helical gear 11. A circular hole 15 is provided on the limiting block 14, and the square shaft 8 is rotatably connected in the circular hole 15, which ensures the meshing effect between the first helical gear 10 and the second helical gear 11, while avoiding the limiting block 14 from hindering the rotation effect of the square shaft 8.

[0031] Specifically, in this embodiment, a bracket 16 is provided on the base 1. The bracket 16 is L-shaped. A second one-way screw 17 is internally threaded to the top of the bracket 16. A third knob 18 is provided at the top of the second one-way screw 17. A pressure plate 19 is movably connected to the bottom of the second one-way screw 17. A slot 20 is provided on both sides of the pressure plate 19. The slot 20 is parallel to the two-way screw 2. Two pressure blocks 21 are slidably connected to the bottom of the pressure plate 19. The two ends of the pressure blocks 21 are L-shaped and are respectively engaged in the two slots 20.

[0032] After the two clamping plates 7 clamp the two fiber arrays onto the first docking seat 4 and the second docking seat 5 respectively, the second unidirectional screw 17 is rotated by the third knob 18, causing the pressure plate 19 to press down. The pressure plate 19 drives the two pressure blocks 21 to press down synchronously, applying the same pressure to the two fiber arrays respectively, thereby ensuring the vertical alignment of the two fiber arrays on the first docking seat 4 and the second docking seat 5, further improving the alignment of the docking and reducing deviation. Under the guidance of the slot 20, the two pressure blocks 21 can move synchronously with the two fiber arrays on the first docking seat 4 and the second docking seat 5, ensuring that the pressure blocks 21 always maintain the pressing effect during the docking movement.

[0033] Specifically, in this embodiment, the pressure plate 19 is provided with two second guide rods 22. Both second guide rods 22 are parallel to the second one-way screw 17. Both second guide rods 22 are slidably connected to the top of the bracket 16. The second guide rods 22 provide stable vertical guidance for the movement of the pressure plate 19, and at the same time can limit the horizontal angular rotation of the pressure plate 19.

[0034] Specifically, in this embodiment, the pressure plate 19 is fastened to the top of the L-shaped end in the slot 20 and is rotatably connected to a ball bearing 23. The ball bearing 23 is rolled in the slot 20, and the ball bearing 23 makes the pressure block 21 move smoothly in the pressing state.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
