Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to an automatic alignment structure for optical fiber connector ferrules. Background Technology

[0002] In fiber optic communication systems, fiber optic connectors are crucial components for enabling detachable connections between optical fibers. The performance of a fiber optic connector largely depends on the alignment accuracy of its ferrule; precise alignment effectively reduces optical signal transmission loss and improves signal transmission quality.

[0036] Example

[0037] like Figure 1-5 As shown, the present invention proposes an automatic alignment structure for fiber optic connector ferrules, including a mounting housing 1. The exterior of the mounting housing 1 is provided with a maintenance cover 2 for replacing and repairing internal components. A mounting base 4 is movably provided inside the mounting housing 1. The inner wall of the mounting housing 1 is provided with two sliding grooves 3. Two connecting plates 5 are fixedly provided at the top and bottom of the mounting base 4. A slider is fixedly provided at the end of the connecting plate 5 away from the mounting base 4. The slider and the sliding groove 3 are movably connected. The cooperation of the slider, the sliding groove 3 and the connecting plate 5 can guide and position the movement of the mounting base 4 within the mounting housing 1, ensuring that the mounting base 4 can move in the correct direction under the action of the elastic structure 8. The mounting base 4 is provided with a ferrule body 7 for achieving precise docking. A circular hole 6 is provided in the center of the mounting base 4. The inner wall of the circular hole 6 and the outer end of one end of the ferrule body 7 are provided with matching threads. Two elastic structures 8 are provided between the mounting base 4 and the mounting housing 1 for automatically adjusting the ferrule body 7.

[0038] The elastic structure 8 includes two connecting blocks 801 for installation. An elastic piece 803 for providing thrust is provided between the two connecting blocks 801. The elastic piece 803 is arc-shaped with its arc opening facing the mounting base 4. Each of the two connecting blocks 801 has a mounting groove 802 on its adjacent side. Both ends of the elastic piece 803 are inserted into the two mounting grooves 802. The elastic structure 8 enables the ferrule to be accurately aligned with the external fiber optic connector ferrule, eliminating the need for manual alignment and improving connection efficiency.

[0039] One side of the connecting block 801 is provided with a limiting structure 9 for limiting the elastic sheet 803. The limiting structure 9 includes two horizontal plates 901 and a limiting seat 902. A limiting plate 903 is movably arranged between the two horizontal plates 901. A limiting block 904 is fixedly arranged on the side of the two horizontal plates 901 that are close to each other. A limiting groove is provided at the top and bottom of the limiting plate 903. The limiting block 904 and the limiting groove are movably connected. A pull plate 905 is fixedly arranged on the front side of the limiting plate 903. The device includes a locking block 906, a locking frame 908 movably mounted on one inner wall of the limiting seat 902, a connecting frame 907 movably mounted on the outside of the locking frame 908, the connecting frame 907 being movably connected to the limiting seat 902, a spring 909 on one side of the locking frame 908, the other end of the spring 909 being fixedly connected to the inner wall of the limiting seat 902, and a push rod 910 movably mounted on one inner wall of the limiting seat 902. The limiting structure 9 enables the quick disassembly of the elastic sheet 803, facilitating subsequent maintenance.

[0040] In this embodiment, during the insertion of the connector into the device, multiple elastic plates 803 provide elastic support and automatic alignment force for the mounting base 4. The mounting base 4 then drives the ferrule body 7, enabling the ferrule body 7 to accurately align with the externally mated fiber optic connector ferrule. The cooperation between the connecting plate 5 and the slider and the slide groove 3 guides and positions the movement of the mounting base 4 within the mounting housing 1, ensuring that the mounting base 4 can move in the correct direction under the action of the elastic structure 8, achieving precise alignment of the ferrule body 7. If the elastic plate 803 needs to be replaced later, the inspection cover 2 is removed, and then the two push rods 910 are pressed simultaneously. The push rods 910 squeeze the locking frame 908, causing it to rotate and separate from the locking block 906. Then, the pull plate 905 is pinched to pull the limiting plate 903 to one side. When the distance between one end of the limiting plate 903 and the limiting seat 902 is greater than or equal to the width of the elastic plate 803, one end of the elastic plate 803 is pulled outward to remove and replace it.

[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
