The present invention relates to an optical fiber cutter for cutting an optical fiber obliquely, and more particularly, by cutting the cutting portion of the optical fiber orthogonally or inclined in the axial direction of the optical fiber so that the tension is automatically moved and rotated by opening and closing the cover formed on the cutting portion. The present invention relates to an optical fiber cutter configured to cut and apply tension and twist to an optical fiber by only opening and closing a cover formed on the cutting portion, and to return the tension portion to its original position.

Yet another aspect of the present invention relates to a portable optical fiber cutting device, and more particularly, in a portable optical fiber cutting device having a straight braid, the linear braid is installed so as to move at right angles to the axial direction of the optical fiber. It extends a long, and relates to a portable optical fiber cutting device that can be easily peeled and cut the optical fiber by installing a stripper of the optical fiber in the optical fiber cutting device.

An optical fiber is a fibrous waveguide that transmits data as light, and is generally used in the form of an optical cable in which several strands are bundled.

As a tool for cutting such an optical fiber, it is conventionally equipped with two covers for pressing and holding the optical fiber in two places, and a slider equipped with a blade for scratching the underside of the optical fiber so that the blade can scratch the optical fiber without shaking. The optical fiber cutter of the structure is used.

However, the above-described optical fiber cutter has a problem in that it is troublesome to operate two covers and push the slider.

The present applicant has proposed an optical fiber cutter having a structure capable of cutting the optical fiber in one operation, and the proposed optical fiber cutter has a cover and a sub-cover, and the sub-cover is synchronously linked to the opening and closing of the cover. A slider having an arm, and at the same time, the cover has a push pin for pushing the arm and a lifting pin for lifting up the arm, and on the other hand, a slider for transferring the mounted cutting knife to scratch the underside of the optical fiber. Is characterized by its configuration with a lever or the like for returning to the original uncut position.

Accordingly, the optical fiber cutter proposed by the present applicant has the advantage of being very convenient to operate and handle since only the opening and closing operation of the cover can cut the optical fiber and reload it to a position ready for the next cutting.

Although the cut surface of the optical fiber is preferably cut perpendicular to the direction of the optical fiber axis, in practice, the cut surface is inclined at only a very small angle with respect to the inclined surface, which in some cases is inversely related to the light passing through the optical fiber junction. There is an example that acts as a cause of light loss by acting as a slope.

As a solution to this, U.S. Patent No. 5,048,908 proposes a method in which the cutting surface of the optical fiber is twisted into 8 shapes so that the function of the reflective surface does not appear, and in this case, the optical fiber cutting is a tensile force with respect to the optical fiber. The cutting surface is applied with excessive torsional force, so that the cut surface appears in a twisted eight shape.

As described above, although the cutting surface of the optical fiber can be cut in the direction orthogonal to the optical fiber axis or in the twisted eight shape, this has a problem that it can only rely on two kinds of cutters having different functions.

In order to solve the above disadvantages, the present applicant has the function of cutting the application of 10-2004-0017563 (name: optical fiber cutter having a tension and torsion function) to a one-touch optical fiber cutter with tension and torsion applied. The optical fiber cutter which can make the cut surface of an optical fiber orthogonal to the optical fiber axis | shaft or a twisted 8 shape was proposed.

However, the technology proposed by the present applicant is to fix the optical fiber to the cutting portion and the torsion portion, and to apply the tension by moving the torsion portion to the fixed optical fiber, and to give the twist by rotating the rotary block of the torsion portion of the optical fiber by closing the cover of the cutting portion There was a disadvantage in that it consists of each step of cutting at an angle and again opening the cover of the cut and manually repositioning the torsion part.

In addition, in the related art, the presser bar formed on the cover to be paired with the support formed on the cutting part for fixing the optical fiber is fixed to the cover, so that the optical fiber cannot be accurately fixed and thus the cutting surface is not accurate.

Yet another aspect of the present invention relates to a portable optical fiber cutting device having a straight braid, wherein the portable optical fiber cutting device having a straight braid has a smaller body and a smaller weight compared to an optical fiber cutting device having a circular braid. However, there are disadvantages in that the cutting surface is not as good as that of the optical fiber cutting device in which the circular braid is installed, and the straight braid has a short lifespan as compared to the circular braid using the circumferential cutting blade.

 In addition, there was an inconvenience of having a cutter for cutting an optical fiber and a stripping machine for stripping the coating of the optical fiber at the same time.

The present invention is to solve the disadvantages of the optical fiber cutter having the tension and torsion function of the application No. 10-2004-0017563 proposed by the applicant,

The present invention combines the function of cutting with a tensile force and torsion, so that the tensioned portion of the cover of the cut portion in the optical fiber cutter can be formed in the optical fiber cutter, the cross section of the optical fiber orthogonal to the optical axis, or twisted eight shape. It is an object of the present invention to provide an optical fiber cutter which allows a rotary block to rotate while simultaneously moving or moving, and causing the tension unit to return to its original position by opening of the cover of the cutting unit.

In addition, the purpose is to install the elastic member on the formed pressing bar of the cover to accurately fix the optical fiber.

In another aspect of the present invention, the short life of the braid of the portable optical fiber cutting device having a straight braid is installed to move the straight braid at right angles to the axial direction of the optical fiber to extend the life of the straight braid more. The purpose is to

In addition, it is an object to be equipped with a stripping machine in a portable optical fiber cutter to peel and cut the optical fiber using a single portable optical fiber cutter.

The present invention to achieve the above object,

A magnetic body is installed on one side of the slider formed in the cutout of the optical fiber cutter, which is proposed by the applicant in Korean Patent Application No. 10-2004-0017563, and a magnetic body is installed on one side of the stand of the tension unit so as to correspond to the magnetic body at a predetermined position.

The slider is moved due to the closing of the cover formed in the cut portion to cut the optical fiber, the tension portion is moved by the repulsive force of the magnetic body installed on the slider and the magnetic body installed on the tension portion to apply tension to the optical fiber, the opening of the cover As a result, the slider is returned to its original position, and the tension portion can be returned to the original position by the attraction force of the magnetic body installed on the slider and the magnetic body installed on the tension unit.

In addition, the push lever may be provided on the cover formed on the cut portion so as to be in contact with the rotary block of the tension portion at a predetermined position.

This allows the rotary block to rotate in contact with the rotary block of the tension unit at a predetermined position by closing the cover.

In addition, the rotary block of the tension unit may be further provided with a rotary block return device installed so that the rotary block can be returned to its original position.

In addition, an elastic member may be installed on the presser bar formed on the cover to stably fix the optical fiber.

The presser bar provided with the elastic member is characterized in that it can stably fix the optical fiber with a base.
