DETAILED DESCRIPTION OF EMBODIMENTS

[0025] Hereinafter, the present invention will be described further with reference to the preferred embodiments and the accompanying drawings.

[0026] As shown in FIG. 1, the present invention discloses a fiber holding tool for the fusion splicer, which comprises a body 1 and a cover 2, among which, the said body 1 and the cover 2 are pivotally connected by a rotating shaft 3.

[0027] The said body 1 is provided with a fiber accommodating groove 11, used for placing a 12-core ribbon fiber having a diameter of 200 m, and the said fiber accommodating groove 11 penetrates the said body 1 in the lengthwise direction; its width is set between 2.80 mm and 2.84 mm.

[0028] As shown in FIG. 2, the said fiber accommodating groove 11 is provided with a rib 12 which is set as a cuboid protruding the fiber accommodating groove 11. The said rib 12 is parallel to the two longer sides of the said fiber accommodating groove 11 and divides the said fiber accommodating groove 11 into two halves in the widthwise direction. The said rib 12 is longer than or equal to the said cover 2, but shorter than the said fiber accommodating groove 11.

[0029] Two sides from the said rib 12 to the fiber accommodating groove 11 are respectively used for placing a 6-core ribbon fiber having a diameter of 200 m. Specifically, when a 12-core fiber needs cutting or welding, the 12-core fiber is longitudinally divided into two 6-core fibers from the cut end or the welding end, and the divided portions are placed on both sides of the rib 12, respectively. When the said cover 2 is closed, the cover 2 can clamp the two separate 6-core fibers.

[0030] When the fusion splicer is used for welding operation, first of all, be sure to place the cut fiber on the V groove. Welding shall be started after the fiber are placed in the V groove at both sides. Because the new 12-core ribbon fiber has a diameter of 200 m, much smaller than the original 12-core ribbon fiber having a diameter of 250 m, the original V groove cannot hold the new 12-core ribbon fiber having a diameter of 200 m. The said rib 12 therefore divides the new fiber into two 6-core fibers, increasing the spacing between the fibers to match the original V groove spacing. In this way, the original fusion splicer can be used for welding.

[0031] As shown in FIG. 1, the said body 1 is provided with a fiber limiting front portion 13 and a fiber limiting rear portion 14, and the upper surface of the said fiber limiting front portion 13 and the said fiber limiting rear portion 14 is higher than the said fiber accommodating groove 11. In this embodiment, the fiber limiting front portion 13 is provided at the front end of the fiber accommodating groove 11, and the fiber limiting rear portion 14 is provided at the middle part of the fiber accommodating groove 11. When the fiber is placed in the fiber accommodating groove 11, the said fiber limiting front portion 13 and the said fiber limiting rear portion 14 can guide the fiber to be fixed in the fiber accommodating groove 11.

[0032] As shown in FIG. 1, the said cover 2 is shorter than the said body 1. The said cover 2 is provided with a fiber fixing portion 21 for fixing the fiber, and the said fiber fixing portion 21 is provided with an elastic body 22 for clamping the fibers in the said fiber accommodating groove 11. The said elastic body 22 protrudes the inner surface of the said cover 2 and its width is larger than that of the said fiber accommodating groove 11.

[0033] Moreover, the said body 1 is also provided with an elastic body accommodating groove 16 which is located at both sides of the said fiber accommodating groove 11. The said elastic body accommodating groove 16 is longer than or equal to the said elastic body 22 in length, and fit with the said elastic body 22 in height and width, with its bottom higher than the said fiber accommodating groove 11 but lower than the said fiber limiting front portion 13 and fiber limiting rear portion 14. When the said cover 2 is engaged with the body 1, the said elastic body 22 can clamp the fiber at a position corresponding to the fiber accommodating groove 11 so that the fiber placed in the said fiber accommodating groove 11 cannot be moved in the vertical direction, and the remainder of the elastic body 22 falls into the elastic body accommodating groove 16.

[0034] Further, the said body 1 is provided with a magnet 15, and the said cover 2 is made of a magnetic material. One end of the said cover 2 may be connected to the said body 1 through the magnet 15 to close the said cover.

[0035] As shown in FIG. 4 and FIG. 5, the said body 1 is also provided with a plurality of connection fixing holes 17 for permanent connection with fiber cleavers and fusion splicers. In this embodiment, the number of the connection fixing holes 17 is two, and the connection with the fiber cleaver and the fusion splicer can be screwed.
