Description

Description: TECHNICAL FIELD The present invention relates to a separating device used for separating a core of an optical fiber tape used for optical communication or the like.

(Prior Art) Conventionally, in order to separate a core wire of an optical fiber tape, an incision was made in a coating of the tape with a blade, and then the fiber was torn by hand.

(Problems to be Solved by the Invention) In the conventional method for separating the core of the optical fiber tape, the fiber strand (single core fiber) is easily damaged, which causes the fiber breakage.

(Object of the Invention) It is an object of the present invention to provide an optical fiber tape separating tool which can easily separate a core of an optical fiber tape without damaging a single fiber.

(Means for Solving the Problems) As shown in FIG.
The two substrates 1 and 2 are connected to each other so as to be openable and closable, and one of the substrates 1 has a positioning groove 3 for positioning the optical fiber tape A, and an optical fiber tape A
And a guide 4 for preventing the optical fiber tape A from detaching from the positioning groove 3 and a separating tooth 5a for separating the core B of the optical fiber tape A. A guide fitting hole 6 into which the guide 4 is fitted;
Separating teeth 5b for separating the core B of the optical fiber tape A are formed, and the separating teeth 5a, 5b are respectively provided on the substrates 1, 2.
Bosses 7a, 7b facing each other, and circular stepped carts 11a, 11b having a small-diameter section 8 and a large-diameter section 9 are mounted so as to be able to protrude and be pushed in. It is characterized in that it is mounted so that the diameter portion 9 faces the same.

(Operation) To separate the core wire B of the optical fiber tape A by the optical fiber tape separating tool of the present invention, the following is performed.

As shown in FIG. 3, the optical fiber tape A to be separated from the core is placed sideways, and is inserted from above into the guides 4 arranged in two rows as shown in FIG.

When the two substrates 1 and 2 are closed in this state, the tape A is sandwiched between the substrates 1 and 2 and set in the positioning groove 3 as shown in FIG. Also, the sharp separating teeth 5a and the bosses 7a, 5b
7b, the optical fiber tape A is sandwiched between them and the tape A is damaged. Further, the tape A is sandwiched between two stepped carts 11a and 11b facing each other as shown in FIG. 5A, and the core B is separated together with the covering layer as shown in FIG. 5B.

In this state, when the optical fiber tape A is drawn in the direction of the arrow in FIG. 3, the core B of the tape A is separated by the amount of the pull.

(Embodiment) FIGS. 1 to 5 show an embodiment of the optical fiber tape separating device of the present invention.

In these figures, reference numerals 1 and 2 denote substrates, and the substrates 1 and 2 are made of a material such as aluminum, for example, so as to fit on the palm of the hand. The two substrates 1 and 2 are mounted on a hinge 12 so as to be freely opened and closed as shown in FIG.
As shown in FIG. 1, both substrates 1 and 2 have opposite surfaces 13a and 13a.
The spring 15 fitted in the fitting holes 14a and 14b of 3b is always pushed outward and opened.

Reference numerals 3 in FIGS. 1 and 4 denote positioning grooves which are formed over the entire length of the substrate 1 in the longitudinal direction so that the optical fiber tape A can be inserted (set) in a horizontal direction.

1 to 3, reference numeral 4 denotes a guide, which is arranged in two rows by protruding a number of pins on both sides in the width direction of the positioning groove 3 at appropriate intervals. The guide 4 is provided with the positioning groove 3
To prevent the optical fiber tape A set in the positioning groove 3 from coming off therefrom.

5a and 5b in FIGS. 1 to 3 are separating teeth. This is for separating the optical fiber tape A, and is formed sharply with a material such as steel so as to be able to bite into the coating of the optical fiber tape A. Also, both separated teeth 5a, 5b
One of the separating teeth 5a protrudes into the guide groove 3 of the substrate 1 and the other separating tooth 5b protrudes from the substrate 2 at a position facing the guide groove 3.

Reference numeral 6 in FIGS. 1 and 3 denotes a guide fitting hole for the guide 4 to be fitted when the substrates 1 and 2 are closed. And the same number as that of the guides 4 are formed at the same positions.

1 to 3, reference numerals 7a and 7b denote bosses, which are pressed by the separating teeth 5a and 5b when the substrates 1 and 2 are closed. The bosses 7a and 7b are mounted on mounting holes 15a and 15b (FIG. 3) formed in the substrates 1 and 2 via springs 16a and 16b. Thus, when the substrates 1 and 2 are open, they are pushed outward by the springs 16a and 16b, but when the substrates 1 and 2 are closed, the separation teeth 5a and 5b
And pushed into the mounting holes 15a and 15b.

1 to 3, reference numerals 11a and 11b denote circular stepped carts for cutting the optical fiber tape A. As shown in FIG. 1, a small-diameter portion 8 and a large-diameter portion 9 are formed on the stepped carts 11a and 11b. Further, as shown in FIG. 3, the substrates 1 and 2 are mounted in the mounting holes 16a and 16b of the substrates 1 and 2 via springs 17a and 17b, and project outward when the substrates 1 and 2 are open. When 1 and 2 are closed, the small diameter portion 8 of the stepped carriage 11a and the large diameter section 9 of the stepped carriage 11b mesh with each other, and the large diameter section 9 of the stepped carriage 11a and the small diameter section 8 of the stepped carriage 11b engage with each other. As well as the steps 10 of the two steps 11a and 11b (Fig. 1)
Thus, the optical fiber tape A is sandwiched and cut as shown in FIG.

(Effect of the Invention) According to the optical fiber tape separating device of the present invention, the optical fiber tape A is set in the positioning groove 3, and after closing both substrates 1 and 2, the tape A is pulled along the positioning groove 3. Thus, since the core B of the tape A can be separated, the operation of separating the core of the optical fiber tape A becomes easy, and there is no fear that the core B is damaged.
