Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary type cable sheathing stripper, and more particularly to a rotary type cable sheath stripping stripper for stripping the coating of a round multicore cable to expose the conductor.

[0002]

2. Description of the Related Art As a conventional technique applied to a cable coating stripping operation for stripping the coating of a round multi-core cable to expose the conductor, a cutting blade is pushed into the boundary between the conductor and the coating covering it. There is a device that moves the blade side or the cable side while the tip of the blade is projected from the outer periphery of the coating to cut the coating up to the outer peripheral portion thereof. As such a device, for example, in a multi-core cable jacket peeling device disclosed in Japanese Patent Application Laid-Open No. 5-292620, the tip of the multi-core cable is clamped in a radial direction by a clamp to apply a strong pressure to deform the cable covering portion due to distortion. A void is formed between the coated portion and the conductor. Then, the blade edge of the cutter is pushed into the space and the cutter is rotated by a predetermined amount while being rotated, whereby the coating is cut off and the conductor of a predetermined length is exposed.

As a conventional cable sheath peeling tool having another structure, a manual device as shown in FIG. 5 is known. In the same figure, the cable sheath stripping device 100 is provided with a cutter 104 arranged at the center of a hand-held handle 102 having a two-pole structure so that the stroke can be adjusted, and strips the cable 3 from the sheath.
Clamper 103 that holds 0 at right angles to the handle 102
Is provided. The stroke adjustment of the cutter 104 is adjusted by the adjustment knobs 101 on both ends of the handle 102. In order to strip the cable 30 by using the cable stripping apparatus 100, first, as a pre-operation, the cable 3 is removed.
After manually cutting the sheath and tapes having the coating of No. 0 with a cutter knife or the like, the cable coating peeling device 100 is set on the cable 30 as shown in the figure. Then, when the stroke position of the cutter 104 is adjusted by operating the adjustment knob 101 and the handle 102 is manually rotated, the coating is cut and removed into a thin hollow disc 105.

[0004]

However, according to the conventional technique in which the cable covering portion is deformed by strain as described above, and the cutter is screwed into the generated gap to make an incision,
There is a problem that it cannot be applied to a high-current cable having a coating that is relatively rigid and difficult to deform. Furthermore, in the above-mentioned conventional cable coating peeling tool,
Troublesome and low productivity work such as cutting in the previous stage, assembling the peeling tool to the cable, adjusting the stroke of the cutter, and manually rotating the handle is required. For this reason, there is a drawback that it takes a long time for peeling and a quick work cannot be performed. Furthermore, since there is no function to control the stripped length of the conductor, it is indispensable to perform a troublesome and unreliable operation such as frequently measuring the stripped portion length during the work. It was not easy to strip the conductor of the desired length, and it was difficult to improve the workability of stripping the cable coating.

The present invention has been made to solve the problems and drawbacks of the prior art. The purpose of the present invention is to facilitate the work of stripping a conductor of a predetermined length and to achieve high productivity, and also for a large current cable. (EN) Provided is a rotary type cable sheathing / peeling tool which can be applied and whose stripping length can be easily set and whose cutter can be easily replaced.

[0006]

In order to achieve the above object, a rotary type cable sheathing stripper according to the present invention is a sheathing stripper for a round cable in which a conductor is coated, and is formed by a hollow cylindrical shape. And a covering holder part that is projected from the inner wall of the covering holder part, and rotates with the rotation of the covering holder part, and gradually cuts and peels off the covering of the cable that makes sliding contact with the inner wall to form a conductor. A coating stripping cutter having a spiral blade edge that is exposed, and a hollow shape that is connected to the rear end of the coating holder part and has a bottom part where the conductor head abuts, and that communicates with the hollow cylinder that forms the coating holder part. A tubular portion having a conductor accommodating hole, a stripping scrap discharge port formed below a coating stripping cutter provided in the coating holder portion, and a continuous portion provided at the rear end of the tubular portion via the tubular portion. The coating peeling cutter Characterized by comprising comprises a chucking portion for imparting a rotational force to the cover holder portion for. Alternatively, the coating peeling cutter 15 includes a peripheral end portion 15A forming one end and a bottom end portion 15 forming at least the other end.
The blade tip 15C is provided on the end surface reaching B, and the blade tip 15C starts to project from the tip end side of the inner wall 1B of the covering holder portion 1 in the central axis direction toward the rear end side of the inner wall 1B and reaches the bottom face portion 7. It is characterized in that it is connected in a spiral shape and is gradually extended in the direction of the central axis.

Alternatively, the coating peeling cutter is formed separately from the coating holder portion, and a cutter mounting groove for mounting the coating peeling cutter is provided on a wall portion of the coating holder portion. Alternatively, the bottom portion of the conductor accommodating hole is configured to be movable in the axial direction of the cylindrical portion.

[0008]

In the rotary cable sheath peeling tool according to the present invention,
While the hollow cylindrical coating holder part is rotated around the axis,
From the hollow end of the sheath holder, the coated cable is
The outer periphery of the coating is slidably contacted with the inner wall of the coating holder portion and continuously pushed (inserted). On the other hand, on the front end side of the inner wall of the coating holder portion, the blade edge at the peripheral end portion of the coating peeling cutter projects toward the central axis. Therefore, the outermost coating of the coated cable pushed into sliding contact with the inner wall is
It hits the edge of the projecting coating stripping cutter, so that the outermost coating at the beginning of the cable is first cut.

Since the blade edge of the coating stripping cutter is spirally continuous from the peripheral end portion to the bottom end portion side, and gradually protrudes from the front end side of the inner wall of the coating holder portion toward the rear end, the cable is When slidingly contacting the inner wall of the covering holder part and pushing it further deeper, the leading end of the cable advances from the blade edge at the peripheral edge portion against which it hits and comes into contact with the blade edge at the bottom edge side. As a result, the coating at the front of the cable is cut deeper inward. At the same time, the coating behind the cable head hits the cutting edge of the peripheral end, so that the coating behind the cable is gradually cut. In this way, when the cable is pushed deeper into the coating holder portion, peeling proceeds, and eventually the cable head comes into contact with the bottom end edge of the coating peeling cutter. Since the cutting edge of the bottom end of the coating stripping cutter projects to the position of the innermost circumference of the cable coating, the cable coating is completely cut to the innermost circumference, and the conductor at the top of the cable is exposed.

Further, as the cable slides against the inner wall of the sheath holder and is pushed deeper into the sheath, the stripping of the sheath progresses from the beginning of the cable to the rear, thus lengthening the exposed portion of the conductor. The exposed conductor advances from the coating holder portion to the tubular portion, and advances in the conductor receiving hole inside the tubular portion toward the rear end of the tubular portion. Further, when the cable is pushed into the covering holder portion, the top of the conductor that is barely exposed abuts against the bottom portion of the conductor accommodating hole, and further pushing of the cable is impossible.

By the way, the length of the stripped conductor is equal to the depth of the conductor accommodating hole when the conductor head comes into contact with the bottom of the conductor accommodating hole. Therefore, if a conductor accommodating hole having a depth equal to the predetermined length of the conductor is used,
The peeling work is automatically completed when the top of the bare conductor comes into contact with the bottom of the conductor housing hole. In this way, by setting the depth of the conductor receiving hole to a predetermined length,
It is possible to easily strip the conductor having a predetermined length with easy work. Further, during this time, the stripping chips are discharged from the stripping chip discharge port on the back surface of the coating stripping cutter, so that the stripping chips do not stay in the cable stripping tool.

Further, the coating stripping cutter is constructed separately from the coating holder part, and the cutter mounting groove of the coating holder part is provided with
By detachably attaching the coating peeling cutter,
Replacement of the coating peeling cutter becomes easy. Furthermore, the locking screw that is screwed into the cutter locking hole formed in the wall of the coating holder part securely locks the coating peeling cutter mounted in the cutter mounting groove, and thus the wobbling of the coating peeling cutter And prevent falling off. Further, when the stopper is fitted into the conductor accommodating hole from the rear end opening of the tubular portion and the locking projection is fitted into the lateral slit of the tubular portion wall, the stopper becomes axially movable inside the tubular portion. After the stopper is moved to a desired axial position, the stopper is slightly rotated, and the locking projection is fitted into the vertical slit provided at a right angle to the horizontal slit, and the locking projection is locked by the vertical slit wall surface. . The stopper is locked in that position by the locking of the locking projection, and as a result, the end surface of the stopper forms the bottom of the conductor receiving hole. As described above, since the stopper is movable and the stopper can be locked at any position, the bottom of the conductor receiving hole can be set at any position in the axial direction of the cylinder. As a result, the conductor accommodating hole having a desired depth is formed, so that the conductor having a desired length can be easily exposed.
