- the clamp section 30A includes, for example, a swing mechanism that swings the pressing section 33A, like the clamp section 30 described above. By swinging the pressing portion 33A with the swinging mechanism, the pressing portion 33A can be swung in a direction approaching the V-groove 11 and a direction away from the V-groove 11 (for example, the Y-axis direction).
- the rotation mechanism 20 rotates the optical fiber holder 10 and the clamp section 30A. Therefore, since the rotation mechanism 20 rotates the optical fiber F while the clamp portion 30A is holding the optical fiber F, the optical fiber F can be efficiently rotated. Since the clamp portion 30 that holds the optical fiber F rotates together with the optical fiber holder 10 when the optical fiber F rotates, it is possible to prevent the optical fiber F from being damaged during rotation. Therefore, the fusion splicer according to the modification can obtain the same effects as the fusion splicer 1 described above.
- FIG. 7 is a side view showing the optical fiber holder 10B, rotating mechanism 20, clamping part 30B, and holder base 40 according to this modified example.
- FIG. 8 is a perspective view showing the optical fiber holder 10B, the rotating mechanism 20, the clamp section 30B and the holder base 40.
- FIG. 1 and 8 in the fusion splicer according to this modified example, the respective configurations of the optical fiber holder 10B and the clamp section 30B are the same as those of the optical fiber holder 10 and the clamp section 30 described above. is different.
- the optical fiber holder 10B includes a base 12B having a V-groove 11 formed thereon and a lid 13.
- the base 12 of the optical fiber holder 10 described above extends to the opposite side of the rotating mechanism 20 from the lid 13 .
- the base 12B of the optical fiber holder 10B does not extend beyond the lid 13 to the opposite side of the rotating mechanism 20. As shown in FIG.
- the clamp section 30B includes a fixed section 31, an extension section 32, a pressing section 33A, and a base 36 having a V groove 37 on which the optical fiber F is placed.
- the direction in which the optical fiber F extends along the V-groove 37 is the Z-axis direction.
- the table 36 is fixed to the mounting surface 41 of the holder table 40, for example.
- the base 36 is arranged so that the V-groove 37 is located on the extension of the V-groove 11 of the base 12 .
- An optical fiber F extending from the V-groove 11 is placed on the V-groove 37 .
- the optical fiber F placed on the V groove 37 is pressed by the pressing part 33A.
- the rotation mechanism 20 rotates the clamp section 30B together with the optical fiber holder 10B. Therefore, since the rotation mechanism 20 rotates the optical fiber F while the clamp portion 30B is holding the optical fiber F, the optical fiber F can be efficiently rotated. Therefore, the fusion splicer according to this modified example can also provide the same effects as the fusion splicer 1 described above. As in each of the modifications described above, the shape and arrangement of the clamp portion can be changed as appropriate.
- each part of the fusion splicer can be changed as appropriate within the scope of the above gist. That is, the shape, size, number, material, and layout of each part of the fusion splicer according to the present disclosure are not limited to the above-described embodiments, and can be changed as appropriate.
- the optical fiber holder 10 is attachable to and detachable from the holder base 40 .
- the optical fiber holder does not have to be detachable from the holder base.
- the fusion splicer may not have the holder base 40 .
- a fusion splicer in which the optical fiber holder 10 is fixed to the rotating mechanism 20 may be used.
