Abstract

PURPOSE:To facilitate the operation for separating core fiber by mounting circular stepped trucks each having a small-diameter part and large-diameter part to two substrates in such a manner that these trucks can be projected and pushed in. CONSTITUTION:The circular stepped trucks 11a, 11b each having the small- diameter part 8 and the large-diameter part 9 are mounted respectively to the two substrates 1, 2 in such a manner that these trucks can be projected and pushed in and that the respective small-diameter parts 8 and large-diameter parts 9 face each other. A tape is set in a positioning groove 3 and an optical fiber tape is inserted between a sharply pointed separating tooth 5a and bosses 7a, 5b, 7b when the two substrates 1, 2 are closed. This tape is inserted by the two stepped trucks 11a, 11b facing each other and is separated together with a coating layer. The operation for separating the core fiber is facilitated in this way and the possibility of damaging the core fiber is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a separation tool used for separating core wires of an optical fiber tape used in optical communications and the like.

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

(Problems to be Solved by the Invention) In the conventional optical fiber tape separation method, the fiber strands (single-core fibers) are easily damaged, which causes fiber breakage.

(Objective of the Invention) An object of the present invention is to provide an optical fiber tape separating tool that can easily separate the core wires of an optical fiber tape without damaging the single-core fibers.

(Means for solving the problem) As shown in FIG. 1, the optical fiber tape separating tool of the present invention has two substrates 1 and 2 connected to each other so as to be openable and closable, and one of the substrates 1 has an optical fiber attached to it. Positioning step 3 for positioning tape A, guiding optical fiber tape A to positioning step 3, and guiding optical fiber tape A from positioning step 3
A guide 4 that prevents the optical fiber tape from coming off, and separation teeth 5a that separate the core wire B of the optical fiber tape A are formed, and the other substrate 2 has a guide fitting hole 6 into which the guide 4 is fitted;
Separation teeth 5b for separating the core MI3 of the optical fiber tape A are formed, and the separation teeth 5b are formed on each of the inner substrates 1.2.
a, 5b, circular stepped carts 11a, 11b having a boss 7a7b, a small diameter part 8 and a large diameter part 9 protrude.
The carts 11a and 11b are mounted so as to be pushable and have the same height difference.
is characterized in that the small diameter part 8 and the large diameter part 9 are attached so as to face each other.

(Operation) In order to separate the core wire B of the optical fiber tape A using the optical fiber tape separating tool of the present invention, the following procedure is performed.

As shown in FIG. 3, the optical fiber tube A to be separated is laid horizontally and inserted from above between the guides 4 arranged in two rows as shown in FIG.

When the two substrates 1.2 are closed in this state, the tape A is sandwiched between the inner substrates 1.2 and the positioning is completed as shown in Figure 2.
is set to In addition, sharp separation teeth 5a and bosses 7a,
The optical fiber tape A is sandwiched between 5b and 7b, and the tape A is damaged. Further, as shown in FIG. 5a, the tape A is sandwiched between the two facing carts 11a and 11b, and the core wire B becomes 111' as shown in the figure. The i-layer is separated.

If the optical fiber tape A is pulled in the direction of the arrow in FIG. 3 in this state, the core wire B of the tape A will be separated by the amount of the pull.

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

In these figures, 1.2 is a substrate, and this substrate l,
2 is made of a material such as aluminum and has a size that can be held in the palm of the hand. These two substrates 1.2 are attached by hinges 12 so as to be openable and closable as shown in FIG. The inner substrate 1.2 also has an opposing surface 13a, as shown in FIG.
The springs 15 fitted into the fitting holes 14a and 14b of the fitting holes 13b always push them outward and open them.

3 in Figures 1 and 4 is the positioning hole, which is the base If
iil, so that the optical fiber tape A can be inserted (set) horizontally.

Reference numeral 4 in FIGS. 1 to 3 denotes a guide, which has a large number of bottles protruding from both sides of the positioning plate 3 at appropriate intervals and arranged in two rows. This guide 4 guides the optical fiber tape A to the positioning point 3, and also guides the optical fiber tape A to the positioning point 3.
This is to prevent the optical fiber tape A set there from coming off.

5a and 5b in FIGS. 1 to 3 are separate teeth.

This is used to separate the optical fiber tape A, and is made of a material such as tr4 material to have a sharp point so that it can bite into the coating of the optical fiber tape A. Also,
One of the two female teeth 5a, 5b is inside the guide groove 3 of the substrate l, and the other separation tooth 5b is inside the guide groove 3 of the substrate l. It is provided protrudingly at a position opposite to the guide 3 at Fi2.

Reference numeral 6 in FIGS. 1 and 3 is a guide fitting hole, into which the guide 4 is fitted when the board 1.2 is closed, and is located in the board 2 facing the guide 4. The same number of guides 4 are formed at the same positions.

7a and 7b in FIGS. 1 to 3 are bosses, which are pressed by the separation teeth 5a and 5b when the inner substrates 1 and 2 are closed. The bosses 7a, 7b are attached to holes 15a, 15b (FIG. 3) formed in the base plate 1.2 via springs 16a, 16b. As a result, when bases it and 2 are open, spring 1
6a16b, but when the boards I and 2 are closed, they are pushed by the separating teeth 5a and 5b and are pushed into the holes 15a and 15b.

Reference numerals 11a and 11b in FIGS. 1 to 3 are circular stepped carts, which are used to cut the optical fiber tape A. This uneven cart 11a.

A small diameter portion 8 and a large diameter portion 9 are formed in the portion 11b as shown in FIG. Moreover, as shown in FIG.
When the boards INI and 2 are open, they protrude outward, but when the boards I and 2 are closed, the small diameter part 8 of the stepped carriage 11a and the large diameter part 9 of the stepped carriage zb
In addition, the large diameter portion 9 of the one-step difference carriage 11a and the small diameter portion 8 of the one-step difference cart 11b mesh with each other and are pushed inward, and the step portions 10 of both step difference platforms 1H1la and 11b
(Fig. 1), the optical fiber tape A is sandwiched and cut as shown in Fig. 5.

(Effects of the Invention) According to the optical fiber tape separation tool of the present invention, after setting the optical fiber tape A at the positioning mark 3 and closing both substrates 1.2, the tape A is pulled along the positioning mark 3 ( Since the core wire B of the same tape A can be separated in a long time, the work of separating the core wires of the optical fiber tape A becomes easy, and there is no fear that the core wire B will be damaged.
