Looking at the optical cable cutting process of the optical cable cutter 10 according to an embodiment, along with the power transmission process of the gear unit as follows.

First, the optical cable to be cut is inserted into the optical cable insertion hole 124.

Next, by applying power from the outside to the upper housing 110 and the lower housing 120 to translate the upper housing 110 and the lower housing 120 in contact with each other as shown in FIG. Accordingly, an upper portion of the first rack gear 410 inserted into the upper housing 110 is translated upward in the upper housing 110 as shown in FIG. 1B.

Next, the first leg gear 410 translates upward and rotates the pinion gear 420 engaged with the first leg gear 410 in a clockwise direction as shown in FIG. 1B. That is, by the pinion gear 420, the translational motion of the first leg gear 410 is converted into a rotational motion.

Next, the pinion gear 420 rotates in a clockwise direction and translates the second leg gear 430 engaged with the pinion gear 420 to the right as shown in FIG. 1B. That is, the rotational motion of the pinion gear 420 is converted into the translational motion by the second rack gear 430.

Next, the second rack gear 430 translates in the right direction along the rack gear guide 432 and the cutting member 300 is fastened to the second rack gear 430 as illustrated in FIG. 1B. Translate in the direction. In addition, the cutting member 300 is also translated in the lower direction as the upper housing 110 and the lower housing 120 are close to each other, the lower end portion is formed with a cutting blade 310 cutting member insertion groove 122 Is inserted into

In other words, the cutting member 300 is the upper housing 110 and the lower housing 120 are in close proximity to each other, which is translated in the right direction and at the same time translated in the lower direction. Accordingly, the cutting member 300 cuts the optical cable inserted in the optical cable insertion hole 124 in the diagonal direction.

On the other hand, in order to reduce the connection loss when connecting optical cables, not only the cut surface of the optical cable should be clean but also perpendicular to the longitudinal direction of the optical cable. In general, an optical cable cutter cuts an optical cable in a vertical direction. When cutting an optical cable in a vertical direction, the cutting surface is rough and there is a high risk of cracks or other defects.

On the other hand, since the optical cable cutter 10 according to an embodiment may cut the optical cable in a diagonal direction, the optical cable cutter 10 may be cleanly cut so that cracks do not occur in the cut surface. In addition, as described above, the cutting member lead-out groove 112, the cutting member insertion groove 122 and the optical cable insertion hole 124 is formed perpendicular to each other, so that the cutting surface of the optical cable is perpendicular to the longitudinal direction of the optical cable to cut the optical cable. Can be.

That is, when the optical cable is cut using the optical cable cutter according to the embodiment, not only the cut surface of the optical cable is clean but also perpendicular to the longitudinal direction of the optical cable, thereby minimizing the connection loss of the optical cable.

In addition, since the optical cable cutter 10 according to an embodiment can perform the cutting operation using only the upper housing 110, the lower housing 120, the gear unit 400, and the like, compared to the general optical cable cutter 10. The structure is simple. Therefore, productivity is good, it is easy to be compact or lightweight, and portability is good. In addition, it is convenient to use because it can simply cut the optical cable by operating the housings without complicated process.

Meanwhile, as shown in FIG. 1A, the optical cable transmitter 10 according to the exemplary embodiment has the gear unit 400 installed at the left side of the housings, and the cutting member 300 is disposed at the left side during the optical cable transmission operation. It translates in the right direction. However, the present invention is not limited thereto, and the same effect can be obtained when the gear unit 400 is installed on the right side of the optical cable cutter 10.

The optical cable cutter according to another embodiment is inserted between the bottom surface of the upper housing and the upper surface of the lower housing to surround the outer circumferential surface of the stopper, and further includes a compression spring that provides a restoring force so that the upper and lower housings are spaced a certain distance apart. Can be.

The optical cable cutter 10 applies external power to the housings which are spaced apart from each other by moving the housings close to each other, and the cutting member 300 transmits the external power through the gear unit 400 as the housings are moved in close proximity to each other. Cut the optical cable. Therefore, in order for the optical cable cutter 10 to perform the cutting operation smoothly, the upper housing 110 and the lower housing 120 are required to be spaced apart by a predetermined distance.

To this end, the optical cable cutter 10 according to the exemplary embodiment may insert the compression spring 230 between the bottom of the upper housing 110 and the upper surface of the lower housing 120 as shown in FIG. 1A.

Accordingly, since the restoring force by the compression spring 230 is applied when the housings are close to each other, the housings are spaced apart from each other by a certain distance without applying a separate external power after the optical cable cutting operation. In addition, when the external power applied to the housings is excessive, the optical cable may be damaged. In this case, the compression spring 230 may be buffered to prevent the optical cable from being damaged.

Meanwhile, in order to prevent the compression spring 230 from being separated, the compression spring 230 may be inserted to surround the stopper 200 as shown in FIG. 1A, and the bottom and bottom housings 120 of the upper housing 110 may be inserted. A spring insertion groove (not shown) may be formed on the upper surface of the) to insert the compression spring 230 therein.

In another embodiment, two or more kinds of optical cable insertion holes having different diameters may be formed.

Different types of optical cables have different diameters, and if the optical cable cutter can cut only the optical cable of a specific diameter, the cost is increased because a separate optical cable cutter must be manufactured for each type of optical cable. Therefore, the countermeasure against this should be considered.

For example, as illustrated in FIG. 1A, two or more kinds of optical cable insertion holes 124 having different diameters may be formed. Accordingly, it is economical because it is possible to cut several types of optical cables having different diameters using the optical cable cutter 10 according to an embodiment.

The present invention has been described above with reference to the embodiments described with reference to the accompanying drawings, but is not limited thereto, and encompasses obvious modifications derivable therefrom. The appended claims are intended to cover such obvious variations.
