Description

OPTICAL FIBER CUTTING DEVICE

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an optical fiber cutting apparatus, and more particularly, to an optical fiber cutting apparatus that can carry an optical fiber at an optical fiber facility.

In general, an optical fiber is a fiber made by elongating a transparent dielectric such as quartz glass or plastic, and passing light through the center of the fiber. In recent years, it has been used in the form of fiber optic cable bundled with multiple strands, and it is made of quartz glass, which is mainly made of high transparency, though it is made of synthetic resin. The optical fiber is composed of a core having a double core structure by a core and a cladding coating the core, and the core is covered with a synthetic resin one or two times.

These optical fibers apply the principle of light propagation and the principle of total reflection, and various advantages arise according to these properties. Since the optical fiber does not interfere or interfere with the external electromagnetic wave, it is difficult to tear, it is small and light, is resistant to bending, accommodates a large number of communication lines in one optical fiber, .

In order to realize the advantages of the optical fiber in such a use, the cut surface of the optical fiber is very fine like the surface of the mirror or the lens, And cut into a smooth mirror surface.

Currently, two types of cutters are used for cutting optical fibers. One is a stationary cutter that cuts the optical fiber while being fixed to a certain table, and the other is a portable hand-held type cutter. As a fixed cutter, an optical fiber automatic cutter of Korean Patent Application No. 10-2003-0026763 is representative. Since the cutter has a complicated and precise structure, a relatively reliable cut surface can be obtained with respect to the optical fiber. However, the cutter can be used only at a limited work site, and it is difficult to carry and handle, resulting in inconvenience. In addition, since it is extremely expensive, it is difficult to use it in all work sites where cutting of the optical fiber is required.

In recent years, a hand-held type cutter has been widely used as an alternative to solve such a problem. A handheld type cutter is a cutter in which two members are mutually cross-coupled and form a scissors shape, and can cut an optical fiber immediately when necessary while the operator carries it. This cutter cuts the optical fiber through the operation of pulling up and widening the cut portion by using the principle of the lever which is the principle of cutting the scissors or the nipper. A structural feature of the cutter is that a path for guiding the optical fiber is provided on one side, and the optical fiber passes through the path, and is interposed at the upper end of both the blades. Thereafter,

The optical fiber is cut in the vertical direction by the blade coupled to the upper end portion. At this time, since the cutting process is performed while the cut portions of the both members intersect with each other, the vertical front face of the optical fiber is cut by the blade.

However, in such a handheld type optical fiber cutter, since the cut surface of the most important optical fiber is formed in an irregular and irregular shape, it is difficult to be applied to an industrial field requiring a precise cut surface. Further, There is a problem in that the optical fiber guard passage which is proceeded is protruded by a considerable length and is inconvenient for handling and carrying.

Therefore, the present inventors have recognized such a problem of the prior art, and after the research, it is easy to work to fix the optical fiber for cutting the optical fiber, and it is possible to easily cut the core of the optical fiber and to make the cut surface of the core perpendicular to the axial direction of the core So that the core can be cut so as to have a cross section.

The present invention relates to an optical fiber cutting apparatus for an optical cable, which comprises an optical fiber cutting guide, the optical fiber cutting guide comprising: And a lid part hinged to the receiving part and rotating about the hinge to cover the upper surface of the receiving part, wherein the optical cable is positioned in the center part between the receiving part and the lid part, and the lid part is smaller than the receiving part The cover portion covers only a part of the optical cable located on the upper surface of the receiving portion in a state in which the cover portion covers the upper surface of the receiving portion and the user can grasp the receiving portion and the optical cable under the cover portion with the hand The present invention also provides an optical fiber cutting apparatus.

1 is a perspective view showing a configuration of an optical fiber cutting apparatus according to an embodiment of the present invention.

Referring to FIG. 1, an optical fiber cutting apparatus according to an embodiment of the present invention includes an optical fiber cutting guide 100 and an optical fiber cutter 200.

The optical fiber cutting guide 100 is a fixture for fixing the core 332 for cutting the core 332. The optical fiber cutter 200 forms a scratch on the core 332 fixed to the optical fiber cutting guide 100, .

The optical fiber cutter 200 may have a blade capable of forming a scratch on the core 332 and may be mounted on a common cable stripper used for removing and cutting the optical cable 300, Alternatively, it may be configured in a form independent of the cable stripper.

The optical fiber cutting guide 100 includes a receiving portion 100 and a lid portion 120.

For example, the receiving portion 100 may have a rectangular plate shape having a predetermined thickness. An optical cable (300) is seated on the upper surface of the receiving portion (100). In order to locate the optical cable, a seating groove 111 extending along the longitudinal direction of the rectangle is formed at the center of the upper surface of the receiving portion 100.

Fig. 2 shows a state where the optical cable is positioned on the receiving portion shown in Fig.

Referring to FIG. 2, the seating grooves 111 may be divided into a plurality of regions having different widths or diameters. For example, a jacket seating portion 111a for seating the jacket 310, which is an outer covering of the optical cable 300, a buffer coating seat portion for seating the buffer coating portion 320 in the jacket portion 310, And a core seating portion 111c on which the core 332 of the optical fiber 330 is seated. These seating portions are sequentially positioned from the lower end of the receiving portion 100 in the order of the jacket seating portion 111a, the buffer coating seating portion 111b and the core seating portion 111c. At this time, the core seating portion 111c is positioned close to the upper end of the receiving portion 100. [

A concave groove 112 is formed in the core seating portion 111c of the seating groove 111. [ The concave groove 112 is a concave groove located below the core seating portion 111c and having a predetermined depth extending downward from the upper surface of the receiving portion 100.

The concave groove 112 is a groove into which the cutting portion of the core 332 that contacts the blade of the optical fiber cutter 200 enters when the core 332 is cut. That is, by pressing the core 332 to the optical fiber cutter 200 at the upper point of the concave groove 112 for cutting the core 332, the cutting portion of the core 332 enters the concave groove 112, And when the optical fiber cutter 200 is separated from the core 332, the curved core 332 is restored again.

The lid part 120 covers the upper surface of the receiving part 100 or is spaced from the upper surface of the receiving part 100. The lid 120 may be hinged to the side of the receiving portion 100 and rotated in a direction proximate to the receiving portion 100 and a direction away from the receiving portion 100 with respect to the hinge 100 . For example, the cover 120 may have a rectangular plate shape having a predetermined thickness. The shape of the lid portion 120 may correspond to the shape of the receiving portion 100.

The lid 120 has a length shorter than the length of the receiving portion 100 and is hinged to the upper end of the receiving portion 100. When the lid part 120 is covered on the upper surface of the receiving part 100 by a length shorter than the length of the receiving part 100 of the lid part 120, the lid part 120 is formed on the upper surface of the receiving part 100 Cover only a part. At this time, the lid portion 120 covers the core seating portion 111c of the seating groove 111 on the upper surface of the receiving portion 100. This is illustrated in FIGS. 3 and 4 as well.

The cladding 331 and the core 332 of the optical fiber 330 positioned in the seating groove 111 on the upper surface of the receiving unit 100 by the lid unit 120 are covered with the lid unit 120, And is securely positioned without being detached from the inner wall 111c.

In this case, the optical cable 300 is exposed in a region below a partial area of the receiving portion 100 covered with the lid 120. The optical cable 300 is held in the process of positioning the optical cable 300 in the seating groove 111 of the receiving unit 100 and positioning the lid unit 120 to cover the upper surface of the receiving unit 100 Can be formed. Therefore, in the process of positioning the optical cable 300 in the seating groove 111 of the receiving unit 100 and positioning the lid unit 120 to cover the upper surface of the receiving unit 100, The optical cable 300 and the receiving unit 100 may be held by hand so that the optical cable 300 and the receiving unit 100 can be separated from each other.

On the other hand, when the lid part 120 covers the core seating part 111c, the lid part 120 is provided with a recessed groove 112 and a recessed part 112c which exposes a part of the core seating part 111c extending from the concave groove 112 A portion 123 is formed. An optical fiber cutter 200 for cutting the core 332 is inserted into the cutout 123. An optical fiber cutter 200 inserted into the cutout 123 presses the core 332 on the concave groove 112 and cuts the core 332 pressed by the optical fiber cutter 200 at this time, A scratch is formed in the cutting portion of the core 332 through this process.

When the optical fiber cutter 200 is inserted into the cutout portion 123 as described above, the cutout portion 123 can be inserted into the optical fiber cutter 200 so that the optical fiber cutter 200 can be inserted into the cutout portion 123 without being perpendicular to the axial direction of the core 332, It is preferable to have a width corresponding to the width or diameter of the cutter 200. In this case, the cutout 123 can easily guide the optical fiber cutter 200 to be inserted perpendicularly to the axial direction of the core 332. [

The cover 120 includes a first auxiliary groove 121 and a second auxiliary groove 121 that help prevent the buffer coating portion 320 and the core 332 of the optical cable 300 located in the mounting groove 111 from being separated from the buffer coating portion 320 and the core 332, 122). The first auxiliary groove 121 and the second auxiliary groove 122 are formed on the surface of the lid 120 facing the upper surface of the receiving portion 100. The first auxiliary groove 121 and the second auxiliary groove 122 correspond to the buffer coating seating part 111b and the core seating part 111c when the lid part 120 covers the upper surface of the receiving part 100 do. The first auxiliary groove 121 and the second auxiliary groove 122 have a width or a diameter corresponding to the buffer coating seating portion 111b and the core seating portion 111c and the lid portion 120 is formed on the receiving portion 100, The buffer coating portion 320 and the core 332 of the optical cable 300 are covered with the buffer coating receiving portion 111b and the core receiving portion 111c of the receiving portion 100, Thereby preventing the portion 320 and the core 332 from being separated.

Meanwhile, when the core 332 is cut, it is preferable that the lid part 120 is fixed to the receiving part 100 without being flow-covered. That is, it is preferable that the contact surfaces of the lid part 120 and the receiving part 100 are fixed. For this purpose, fixing means are provided between the lid portion 120 and the abutting surfaces of the receiving portion 100. [ In one example, the fastening means may be a magnet 130. The magnet 130 may be installed on the upper surface of the receiving unit 100 and the upper surface of the receiving unit 100 on the lid unit 120. Each of the magnets 130 may be attached to each other to fix a state in which the receiving portion 100 and the lid portion 120 are in contact with each other.

Hereinafter, a process of cutting a core using the core cutting apparatus according to one embodiment of the present invention will be described.

The cover layer of the optical cable 300 is first peeled so that the core 332 is exposed to the outside. In this process, the jacket portion 310 and the buffer coating portion 320 are removed with a cable stripper, and the fiber yarn covering (not shown) is gathered on one side (for example, on the opposite side of the exposed core). At this time, the jacket portion 310 removes a length longer than the buffer coating portion 320 so that the buffer coating portion 320 can be exposed, and the cladding 331 of the optical fiber 330 can expose the core 332 The longer the length than the core 332 is.

After the covering of the optical cable 300 is removed, the optical cable 300 is placed in the seating groove 111 of the receiving portion 100. At this time, the jacket portion 310 is located at the jacket seating portion 111a, the buffer coating portion 320 is located at the buffer coating seating portion 111b, and the core 332 is positioned at the core seating portion 111c . After the optical cable 300 is positioned as described above, the user holds the lower end of the receiving unit 100 by hand so that the optical cable 300 is not separated from the receiving groove 111.

The lid unit 120 is rotated toward the receiving unit 100 while holding the receiving unit 100 and the optical cable 300 by hand to cover the lid unit 120 on the upper surface of the receiving unit 100. [ At this time, the core 332 located at the core seating portion 111c is covered with the lid portion 120 and fixed within the seating groove 111, and a portion of the core 332 is covered with the cut portion 123 of the lid portion 120, Lt; / RTI >

Next, the optical fiber cutter 200 is inserted into the cutout 123 with the blade of the optical fiber cutter 200 facing the core 332 and the optical fiber cutter 200 is pulled toward the core 332 Click. At this time, the cutting portion of the core 332, which is in contact with the blade of the optical fiber cutter 200, is bent into the concave groove 112 while being scratched by the blade of the optical fiber cutter 200. This is well illustrated in FIG. The warped core 332 is then restored.

The cover part 120 is separated from the receiving part 100 by rotating the cover part 120 in the direction away from the receiving part 100 so that the optical cable 300 is separated from the receiving part 100, Is taken out from the seat groove (111).

Finally, if the core 332 is bent by bending the end of the core 332 while holding the end of the core 332 with one hand while holding the jacket portion 310 or the buffer coating portion 320 of the optical cable 300 with one hand, The portion where the scratch is formed is cut.
