Description

An electric wire clothing cutter

The present invention relates to a wire sheathing cutter, and more particularly to a wire sheathing cutter which cuts the sheath of the wire to facilitate the exposure of the copper wire.

In general, when connecting the wire 10 to the connection terminal or interconnect, it is necessary to remove the cover 13 of the terminal. Thus, in order to remove the covering 13 of the electric wire 10, the coating 13 of the terminal part of the electric wire 10 is cut | disconnected longitudinally, as shown in FIG. The incision is then made at several points along the circumference of the wire 10.

Then, the peeled coating 13 is peeled in the longitudinal direction as if the banana is peeled off, and then cut with a knife to expose the copper wire 15.

According to the prior art, the knife was often damaged when the sheath of the wire was cut in the longitudinal direction. And, there was a problem that the knife is cut into the copper wire to cut the copper wire. And, a lot of power was not properly incision was difficult to work.

The wire covering cutter 100 according to the present invention includes a body 110 formed of side plates 113 formed on both sides, and an upper plate 117 connecting upper ends of the side plates 113, wherein the upper plate ( The blade 120 protrudes from the lower surface 118 of the 117.

According to the wire coating cutter according to the present invention, since the blade 120 is not exposed in the state in which the blade 120 is inserted into the wire 10 by protruding the tip of the blade 120 into the body 110. It can prevent hand injury. In addition, by simply holding the body 110 and pulling in the longitudinal direction of the wire 10 there is an effect that can be easily cut without great effort by forming the incision line by itself.

Hereinafter, a configuration, an embodiment, and an operation example of the present invention for solving the above problems with reference to the accompanying drawings are as follows.

Figure 2 is a cross-sectional view showing a first embodiment of the wire coating cutting machine according to the present invention, Figure 3 is a perspective view showing an example of cutting the coating of the wire with the wire coating cutting machine of the first embodiment according to the present invention, Figure 4 Fig. 5 is a perspective view showing an example of cutting the coating of an electric wire with the wire coating cutter according to the second embodiment of the present invention. It demonstrates together as sectional drawing along the C-C 'line | wire.

In general, when connecting the wire 10 to the connection terminal or interconnect, it is necessary to remove the cover 13 of the terminal. Thus, in order to remove the covering 13 of the electric wire 10, the coating 13 of the terminal part of the electric wire 10 is cut in the longitudinal direction. The incision is then made at several points along the circumference of the wire 10. The copper wire 15 can then be exposed by pulling downward the cut sheath 13 like a banana peel.

In the present invention, it is characterized in that the cover 13 of the terminal portion of the wire 10 can be cut safely and easily in the longitudinal direction.

To this end, the present invention is configured as follows.

First, the first embodiment will be described with reference to FIGS. 1 and 2 as follows.

Body 110 composed of a side plate 113 in contact with both sides of the electric wire 10 and the top plate 117 connecting the upper end of the side plate 113 is configured. And, the lower surface 118 of the upper plate 117 is configured to protrude a blade 120 penetrating through the sheath 13 of the wire (10).

The distance between the inner surface of the both side plates 113 corresponds to the diameter of the wire 10, the distance is adjusted to allow the transfer of the present invention to put the wire 10 between both side plates 113.

Therefore, when the wire 10 is sandwiched between the side plates 113 and pressed toward the upper plate 117, the blade 120 penetrates the sheath 13 of the wire 10. In this state, as shown in FIG. 3, when the body 110 of the present invention is held and transferred in the longitudinal direction of the wire 10, the sheath 13 is cut. In this way, a plurality of incisions 90 may be formed along the circumference of the wire 10. Then, the incised cover 13 is peeled downward like peeling a banana, and then cut to allow the copper wire 15 to be exposed.

Looking at the second embodiment of the present invention through FIGS. 4 to 7 as follows.

Body 110 composed of a side plate 113 in contact with both sides of the electric wire 10 and the top plate 117 connecting the upper end of the side plate 113 is configured. The blade 120 is mounted to the upper plate 117 by the mounting means 200.

The mounting means 200 is formed through the upper plate 117, the slot 210 is formed long in the side (both side plate direction) so that the conveying block 230 to be penetrated to be passed laterally is formed, The slot 210 is formed with a stepped protrusion 215 protruding along the inner circumference to support the transfer block 230 to be described later.

In addition, the transfer block 230 penetrates through the slot 210 and is seated on the step 215. The transfer block 230 is formed with a slit 233 is formed in the longitudinal direction of the wire 10 and penetrated from the upper to the lower side through which the blade 120 to be passed through. The blade 120 penetrates the slit 233. In addition, the side of the transfer block 230 is formed with a tab hole 235 communicated with the slit 233, the bolt 237 is fastened to the tab hole 235 to press the blade 120 is configured.

In addition, the support block 220 in which the tab hole 223 is formed laterally (side plate direction) in the upper plate 117 so as to face the side surface 239 in which the tab hole 235 is not formed in the transfer block 230. Is formed. A bolt 225 is formed through the tab hole 223 so that the end 226 faces the transfer block 230. The bolt 225 is configured such that the end 226 is pivoted to the side surface 239. For example, a flange 227 is formed at the end 226, an inner hole 231 is formed at the side surface 239 of the transfer block 230, and the inner hole 231 is accommodated. ) Is a stepped portion 232 protruding inwardly along the periphery is formed to the outside of the flange 227 is prevented.

In addition, by forming a tab hole 115 in the side plate 113 of the one side, the bolt 300 is fastened to the tab hole 115 to press the wire 10 is configured to correspond to the wire diameter of the wire 10 do.

Looking at the operation example of the second embodiment, first, after releasing the bolt 237 fastened to the transfer block 230, the blade 120 is moved up and down to accurately penetrate the coating 13 and the copper wire ( 15) Adjust so as not to damage it. Then, the bolt 237 is fastened to press the blade 120 to prevent the transfer.

Then, when the bolt 225 fastened to the support block 220 is turned in the forward and reverse direction, the transfer block 230 is reciprocated laterally along the slot 210 in accordance with the transfer of the bolt 225. Therefore, adjustment is possible so that it may be located in the center of the axis of the electric wire 10.

Then, the electric wire 10 is inserted between both side plates 113. Then, the bolt 300 is rotated so that the wire 10 is positioned between the end of the bolt 300 and the mating side plate 113. That is, according to this structure, it is possible to respond to the wire 10 of various wire diameters. At this time, the tip of the blade 120 is in a state passing through the coating 13 of the wire (10).

When the present invention is pulled in the longitudinal direction of the electric wire 10 in this state, the coating 13 can be easily cut. After forming a plurality of cut lines 90 along the circumference of the wire 10 in this manner, the longitudinally cut sheath 13 is pulled downward as if peeling banana. The copper wire 15 can be exposed by cutting off the stripped coating 13.

Therefore, according to the present invention, the tip of the blade 120 protrudes inside the body 110, so that the blade 120 is not exposed in the state in which the blade 120 is inserted into the wire 10. You can prevent accidents.

In addition, by simply holding the body 110 and pulling in the longitudinal direction of the wire 10 there is an advantage that the incision is formed by itself can be easily cut without great effort.
