Description

Technical Field

[0001] The invention relates to an optical fiber positioner suitable for large core diameters, and belongs to the technical field of optical fibers. Background Art

[0002] Currently, the required optical fibers for large core bundles are identified through the traditional branching method, where the corresponding luminescent fibers are searched for at the bundle end face to determine their locations. This method requires multiple injections of light into the branches to locate the fiber locations corresponding to the bundle. First, the required fiber locations within the bundle must be confirmed, and then the corresponding branches are identified through injections of light. However, if too many fibers are required, multiple inspections are required, increasing the time required to locate the desired fibers. Furthermore, the prolonged search for luminescent fibers can easily cause visual fatigue and reduce accuracy. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an optical fiber locator suitable for large core diameters in response to the above-mentioned prior art, which can quickly locate the required optical fiber position and improve operation efficiency and accuracy.

[0004] The technical solution adopted by the present invention to solve the above problems is: a fiber optic positioner suitable for large core diameters, the fiber optic positioner is arranged on the outer core of the fiber optic bundle end, the fiber optic positioner includes a ring, a light blocking plate is provided in the ring, the light blocking plate covers one end of the ring, and the two are fixedly connected; a plurality of light leakage holes are provided on the light blocking plate, and any of the light leakage holes corresponds to the position of the required optical fiber; the light blocking plate is also provided with an alignment groove, and a positioning piece is provided on the fiber optic bundle end, and the ring is rotated to position the alignment groove and the positioning piece.

[0005] The inner diameter of the collar matches the outer diameter of the outer ferrule.

[0006] The aperture of the light leakage hole is 1 / 4 of the core diameter of the optical fiber, and the aperture accuracy of the light leakage hole is ±10μm.

[0007] The position accuracy of the light leakage hole is ±20 μm.

[0008] The collar and the light shield are respectively made of 304 stainless steel.

[0009] Compared with existing technologies, the present invention offers advantages in that it is suitable for large-core fiber locators. A collar fits over the outer ferrule at the fiber bundle end, ensuring the collar is stable. The collar is slowly rotated to align the alignment groove with the positioning member on the outer ferrule, which then engages the positioning member. When a flashlight shines on the collar, light is emitted through the light leakage hole, generating a signal from the optical fiber. The optical fiber that passes light is the desired optical fiber. This design not only has a simple structure and is easy to operate, but also enables quick and accurate locating of the desired optical fiber, improving both efficiency and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a schematic diagram of an optical fiber positioner suitable for large core diameters according to an embodiment of the present invention;

[0011] In the figure, there are 1 ring, 2 light blocking sheets, 3 light leakage holes, and 4 alignment grooves. DETAILED DESCRIPTION

[0012] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, in this embodiment, a fiber optic positioner suitable for large core diameter is provided on the outer core of the optical fiber bundle end. The fiber optic positioner includes a ferrule 1 made of 304 stainless steel. The inner diameter of the ferrule 1 matches the outer diameter of the outer core, so that the ferrule 1 is sleeved on the outer core. A light blocking plate 2 is provided in the ferrule 1. The light blocking plate 2 is also made of 304 stainless steel. The light blocking plate 2 is fixed to the ferrule 1 to seal one end of the ferrule 1. Six light leakage holes 3 are provided on the light blocking plate 2. The light leakage holes 3 correspond to the positions of the six required optical fibers, and the position accuracy of the light leakage holes 3 is 1μm. An alignment groove 4 is also provided on the light blocking plate 2. The alignment groove 4 corresponds to the positioning piece provided on the outer core. Rotate the ferrule 1 so that the alignment groove 4 is inserted into the positioning piece.

[0014] The aperture of the light leakage hole 3 is 1 / 4 of the core diameter of the optical fiber, and the aperture accuracy of the light leakage hole 3 is 2 μm.

[0015] The ferrule 1 is placed over the outer ferrule at the fiber bundle end, ensuring that the ferrule 1 does not wobble. Slowly rotate the ferrule 1 until the alignment groove 4 aligns with the positioning feature on the outer ferrule, effectively inserting the positioning feature into the alignment groove 4. Shine a flashlight through the ferrule, and the light will escape through the light leakage hole, generating a signal from the optical fiber. The optical fiber that passes the light is the desired optical fiber. This simple structure and convenient operation also allow for quick and accurate identification of the desired optical fiber, improving both efficiency and accuracy.

[0016] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
