And connect it to other cables.

The rotary cutting frame 2 (returning to FIG. 1, FIG. 2, FIG. 3, and FIG. 4) includes a pair of holding members 8, 9 for holding the cable 1, and a pair of holding members 8, 9 for holding the cable 1. A plurality of guide rods 10 held so as to be able to approach and separate from each other;
9, a spacing adjustment mechanism 11 for holding the mutual spacing dimension S so as to be adjustable as appropriate, handles 12, 12 protruding from the outer surfaces of the holding bodies 8, 9, and fixed to one holding body 8. A cutter holder 13 and a cutter 14 attached to the holding body 8 via the cutter holder 13.

The one holding body 8 has a substantially C-shaped light metal block body 15a having right and left cutouts 48, 48 at the top and bottom. And guide rollers 17 which are in rolling contact with the outer peripheral surface.

The other holding member 9 has a light metal block 15b having a substantially C-shape in a front view, and guide rollers 17 pivotally mounted inside the block 15b and rollingly contacting the outer peripheral surface of the cable 1.
And consisting of

The block bodies 15a and 15b have, specifically, opposed concave peripheral surfaces 22 which are curved along the outer peripheral surface of the cable 1 and which are opposed to each other and which are arc-shaped in a front view. Two upper and lower guide rollers 17 are disposed at the front end of the peripheral surface 22, and two upper and lower guide rollers 17 are disposed at the rear end of the opposing concave peripheral surface 22.

More specifically, as shown in FIG. 1, FIG. 2 and FIG. 7, at the corresponding positions on the front and rear surfaces of the block bodies 15a and 15b, there are concave recesses 16 opening in one direction in the front-rear direction and inward. Are formed, and the corresponding concave and recessed portions 16,
A screw hole 20 communicating between the 16 is formed. This screw hole 20
Has an internal thread 19 inside.

The blocks 15a and 15b are desirably formed by, for example, aluminum die casting, but may be formed by a light alloy other than aluminum.

The guide roller 17 has a shaft portion 21 in which a male screw portion is formed, and the shaft portion 21 is screwed into the screw hole 20. It is pivotally mounted in the stored state so as not to protrude backward.

The axis of the guide rollers 17 is parallel to the axis of the cable, and the outer peripheral surfaces of the guide rollers 17 project only inward of the block bodies 15a and 15b.
Here, it is preferable that the guide roller 17 itself be a needle bearing or a ball bearing, and that the outer ring of the guide roller 17 be partially protruded inward from the concave portion 16 so as to contact the outer peripheral surface of the cable 1.

As described above, when the guide roller 17 itself uses a bearing, the block members 15a and 15b have high rigidity, so that the guide rollers 17 can rotate with high precision without deflection.

Further, as shown in FIG. 8, a guide rod 10 is provided at the front and rear ends of the left and right ends of the block body 15a of the holding body 8.
The ball slide bearing 23 which slidably receives in the longitudinal direction thereof is embedded.

Here, the ball slide bearing 23 is composed of a cylindrical bush 26, and a plurality of rotary members rotatably provided in the bush 26 so as to slightly project inward from the inner peripheral surface of the bush 26. Flexible metal spheres 27 ...

More specifically, a through hole 24 is formed in the block body 15a, and a ball slide bearing 23 is fixedly fitted in the through hole 24. Numerals 25 are screw members for fixing the ball slide bearing 23 to the block body 15a.

Thus, the small metal balls 27 are brought into rolling contact with the outer peripheral surface of the guide rod 10, and the guide rod 10 can move smoothly in the longitudinal direction.

The base end of the guide rod 10 is fixed to the other holding member 9 (see FIGS. 1 and 2).

Therefore, the holding bodies 8 and 9 can be connected to each other so that they can be smoothly approached and separated from each other.

As described above, the block members 15a and 15b are substantially C-shaped when viewed from the front, and the concave portions of the block members 15a and 15b are formed.
Since the guide roller 17 is pivotally mounted on the block 16 in the housed state, and the ball slide bearings 23 are buried in the block body 15a, the holding bodies 8, 9 have a simple shape with almost no protrusion. . Therefore, there is almost no portion that gets caught on clothing, body, etc. during use, and there is an advantage that handling becomes easy.

Next, as shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 8, the spacing adjusting mechanism 11 is provided at the upper and lower ends of the holding members 8, 9, and connects the holding members 8, 9 to each other. A bolt handle 28, a small handle portion 29 fixed to the base end of the bolt handle 28, and a nut member 30 screwed to the bolt handle 28 so as to be able to advance and retreat.
And

The bolt rod 28 is rotatably inserted into a hole penetrating through the block 15b of the other holding member 9, and a small handle portion 29 is formed in a notch formed in an outer opening of the hole. Are configured to abut against each other.

The nut member 30 is embedded in the block 15a of one of the holding members 8 (see FIGS. 4 and 8). It is also preferable to form a screw hole directly in the block body 15a instead of the nut member 30 of the gap adjusting mechanism 11.

Although not shown, a resilient member such as a coil spring that resiliently urges the holding members 8 and 9 in opposite directions (separating direction) (for example, by externally fitting the bolt rod 28). )
It is also desirable to attach.

Thus, the distance adjusting mechanism 11 includes the holding body 8,
9 is restricted from moving in the separating direction. In addition, small handle part
By rotating the bolt rod 28 into and out of the nut member 30 by turning 29, the mutual spacing dimension S between the holding members 8, 9 can be adjusted (see FIG. 3).

Accordingly, the cable 1 is inserted between the holding members 8 and 9 and the holding members 8 and 9 are brought close to each other until the outer peripheral surface of the cable 1 contacts the guide rollers 17. The nut member 30 of the adjustment mechanism 11 is
If the screw is advanced until the tip surface of
The gap between the holding bodies 8 and 9 is maintained in that state, and the rotary cutting frame 2 can be attached to the cable 1 so as to be rotatable in the circumferential direction around the cable 1 (see FIGS. 1 and 2).

In order to remove the rotary cutting frame 2 from the cable 1, the small handle portion 29 is rotated in the reverse direction to retreat the bolt rod 28, and the holding members 8, 9 are separated from each other.

Next, as shown in FIGS. 9, 10 and 11, the cutter 14 comprises a cutter main body receiving plate 31 and a cutter main body receiving plate 31.
And a cutter body 32 to which the protruding length of the blade portion 33 is adjustable. Also, the blade portion 33 of the cutter body 32
Is composed of a cutting edge 34a for cutting in the cable radial direction and a cutting edge 34b for cutting in the axial direction of the cable, and the cutting edge 34a and the cutting edge 34b are formed at right angles.

An elongated hole 35 penetrates through the cutter body 32, and a bolt member 36 for attaching the cutter body 32 to the cutter body receiving plate 31 is inserted into the elongated hole 35 so that the blade portion 33 projects from the receiving plate 31. The length is adjustable. 70 is an annular washer, and 71 is a spring washer.

Further, as shown in FIGS. 12 and 13, the base end of the cutter body receiving plate 31 (ie, the base end of the cutter 14).
A swinging cylinder 62 having a guide hole 63 is inserted into the hole 61. A notch depth adjusting rod 45 (described later) of the moving guide frame 3 is reciprocally inserted into the guide hole 63 of the swing cylinder 62.

[0041] Thus, and with adjustable form inclination angle theta ₁ of the cable axis and cutting depth adjustment rod 45 in the swing of the swing cylinder 62 (see FIG. 23).

That is, (back to FIGS. 12 and 13), on the inner peripheral surface of the hole 61 of the cutter main body receiving plate 31, both ends in the longitudinal direction of the cutter 14 (ie, in the cable radial direction). The end face has a mountain-shaped cross section. This allows the swing cylinder 62 to swing in the direction indicated by arrow A in the figure.

In the illustrated example, the oscillating cylinder 62 is a ball slide bearing. Thus, the cutting depth adjusting rod 45 can reciprocate extremely smoothly (without rattling) with respect to the swing cylinder 62.

It is to be noted that the oscillating cylinder 62 may be made of only a cylindrical sliding bearing (bush) made of sintered oil-impregnated metal, brass, or plastic.

A circumferential groove is formed at each of the front and rear ends of the oscillating cylinder 62, and a C-shaped retaining ring 6 is formed along the groove.
Externally fit 4, 64. Furthermore, a spring member 6 such as a compression coil is provided between the front and rear surfaces of the cutter body receiving plate 31 and the surfaces of the C-shaped retaining rings 64 and 64 facing the front and rear surfaces of the oscillating cylinder 62.
Fit 5, 65 outside.

The C-shaped retaining rings 64, 64 and the spring members 65, 65 can prevent the swing cylinder 62 from coming off the hole 61 of the cutter body receiving plate 31, and can also prevent the swing cylinder 62 from moving forward and backward. The part can always be matched with the hole 61 of the cutter body receiving plate 31.

Further, as shown in FIG.
The receiving surface 37 for receiving the cutter body 32 of the 31 is inclined by a predetermined angle θ with respect to the front surface of the holding body 8.

Thus, the cutting angle of the cutter body 32 matches the predetermined angle θ. That is, the cutter body 32 is inclined by a predetermined angle θ with respect to a plane orthogonal to the axial direction of the cable 1, and the cutting pitch in the radial direction by the cutting edge 34a is determined by this angle.

The cutter holder 13 is fixed to the holding body 8 by bolt members 40, 40, and is fixed to the left and right front sides of the substrate 38 by mounting screws 41 to hold the cutter 14. Holding plates 39, 39 (see FIGS. 10 and 11).

More specifically, a concave groove 42 in the cable radial direction for fitting the cutter body receiving plate 31 is formed on the front side of the substrate 38. Then, the inner edges of the holding plates 39, 39 project more inward than the left and right inner walls of the concave groove.

That is, a T-shaped dovetail groove is formed by the concave groove 42 of the substrate 38 and the inner edges of the holding plates 39, 39, and the cutter 14 is fitted into the dovetail groove so as to reciprocate in the cable radial direction. Is done.

A screw hole 43 communicating with the inside of the concave groove 42 is formed on one of the left and right side surfaces of the substrate 38, and the cutter 14 is fixed to the screw hole 43 by contacting the side surface of the cutter body receiving plate 31. A tightening screw member 44 having a knob portion that can be screwed is provided so as to be able to advance and retreat.

It is to be noted that the cutter holder 13 can be freely formed by an integral member having a T-shaped dovetail groove.

When the tightening screw member 44 is loosened, the cutter 14 becomes movable in the cable radial direction (see FIGS. 9 and 10).
10).

Next, returning to FIGS. 1, 2, 3 and 4, the moving guide frame 3 is slidably connected to the reciprocally movable cutter 14 so as to reciprocate in the cable axial direction. A cutter cutting depth adjustment rod 45 for moving the cutter 14 in the cable radial direction, a guide rod 46 for guiding the adjustment rod 45 so as to be able to reciprocate along the cable axial direction, and a front end of the guide rod 46 Cable radial connecting members 47a, 47b erected at the rear end
And

Further, the positions of the distal ends of the connecting members 47a and 47b in the cable radial direction can be adjusted.
a, 47b, the front end and the rear end of the cutter cutting depth adjusting rod 45 are connected via oscillating parts 59, 59, respectively, and the cable axis of the cutter cutting depth adjusting rod 45 is connected. Tilt angle θ ₁
(See FIG. 23) is adjustable.

The guide rod 46 has a guide rod body 49, 49 which is reciprocally movable in a direction parallel to the cable axis direction penetrating the block body 15a of the holding body 8, and has both ends attached to and detached from the front end thereof. A front bridging member 50a, which is freely fixed, and a rear bridging member, whose both ends are fixed to the rear ends of the guide rod bodies 49, 49;
50b.

The front bridge member 50a of the guide rod 46 includes
A contact plate portion 60 that contacts the end face of the cable 1 is provided.
The contact plate 60 is provided in a direction perpendicular to the cable axis.

The block body 15a is formed with through-holes through which the guide rod bodies 49, 49 are inserted, and ball slide bearings 51 for receiving the guide rod bodies 49, 49 are embedded in front and rear ends of the through-holes. (See FIGS. 9 and 10).

As shown in FIGS. 15 and 16, the connecting members 47a and 47b are screwed into screw holes formed in the front bridge member 50a and the rear bridge member 50b of the guide rod 46, respectively, so as to be able to advance and retreat. A threaded rod that is fitted and whose tip protrudes outward in the cable radial direction
And a knob 53 attached to the tip of the screw rod 52.
And a bulging portion 54 provided near the tip of the screw rod 52 adjacent to the knob portion 53 and having a spherical outer peripheral surface.

Reference numeral 55 denotes a screw member which is screwed into the screw rod 52 so as to be able to advance and retreat, and is pressed against the front / rear bridging members 50a, 50b to be connected to the connecting member.
An annular fixture (lock nut) for fixing 47a, 47b.

The connecting member 47a at the front is short.
The rear connecting member 47b is elongated.

It is also preferable that the connecting members 47a and 47b can be exchanged for ones having different lengths, for example, ones longer or shorter than those shown in the drawings.

The cutter cutting depth adjusting rod 45 is provided with an adjusting rod main body 57.
And a mounting member 58a having a front end portion of the adjusting rod main body 57 detachably mounted and swingably mounted on the front connecting member 47a, and a rear end of the adjusting rod main body 57 fixedly connected to the rear end. And a mounting member 58b which is mounted on the member 47b so as to swing freely.

Reference numeral 66 denotes a mounting member 58a for connecting the front end of the adjusting rod body 57 to the mounting member 58a.
The cutter cutting depth adjusting rod 45 can be expanded and contracted by loosening the screw 66 with the knob. Thus, the length of the adjustment rod 45 can be made to correspond to the change in the distance between the front and rear oscillating portions 59, 59.

The mounting members 58a and 58b have, specifically, mounting holes 56 and 56 whose inner surfaces are spherical concave surfaces which are in sliding contact with the outer peripheral surfaces of the bulging portions 54 and 54 of the connecting members 47a and 47b, respectively. .
That is, the oscillating portion 59 is a universal joint having a spherical bearing.

As the oscillating portion 59, the bulging portion 54 is a pin member parallel to the front and rear bridging members 50a, 50b of the guide rod 46, and the both ends of the cutter cutting depth adjusting rod 45 are used. It is also preferable that the pin member is swingably mounted around the axis of the pin member.

By turning the knob 53 of the connecting members 47a and 47b to advance and retreat the screw rod 52 according to the above-described configuration, for example, as shown in FIGS. 14 (a), (b) and (c). In addition, the radial position of the distal end of the connecting members 47a, 47b can be adjusted. That is, the distances N _{1 and} N ₂ between the front and rear ends of the guide rod 46 and the front and rear ends of the cutting depth adjusting rod 45 can be adjusted.

Therefore, the inclination angle θ ₁ of the cutter cutting depth adjusting rod 45 with respect to the cable axis can be changed. Further, by changing the inclination angle θ ₁ , as described later, the inclination angle θ ₂ of the tapered cutting surface of the cable 1 is changed.
Can be adjusted.

Further, as shown in FIGS. 14A and 14C,
Can be moved parallel to the inclination angle theta ₁ to the cutter cutting depth adjustment rod 45 to the cable axial direction is constant. Thus, it is possible to very easily adjust the projecting dimension Y of the left cutter 14 to the inclination angle theta ₁ is constant (see FIG. 9 and FIG. 10). Therefore, the protrusion dimension Y of the cutter 14 at the outlet can be quickly adjusted, and the change in the outer diameter dimension D of the conductor 4 of the cable 1 can be easily accommodated.

Next, as shown in FIG. 17, the width W of the contact plate 60 is set to be at least half the outer diameter D of the conductor 4 of the cable 1.

As a result, the area of the contact plate portion 60 that receives the end face of the conductor 4 becomes large. Therefore, as shown in FIG. 18, for example, even when the end section of the conductor 4 of the cable 1 has irregularities, the contact plate portion 60 can be smoothly rotated about the cable axis with respect to the conductor 4, and During the rotation around the cable 1, the contact plate portion 60 maintains a fixed position in the cable axial direction.

Therefore, the boundary line K between the tapered portion of the insulator 6 of the cable 1 and the uncut outer peripheral surface is
Can be prevented from meandering, and a terminal having a high degree of finish suitable for connection of the cable 1 can be obtained.

The outer diameter D of the conductor 4 of the cable 1 is
When it is set to 100%, the width W of the contact plate portion 60 is set to 50% or more as described above, but is preferably set to 70% or more.

Next, the tool has a lock mechanism L for holding one of the movement of the cutter 14 in the cable radial direction and the movement of the moving guide frame 3 in the cable axial direction so as to be able to freely hold and detach. (FIGS. 1, 3, 4, and 9).
reference).

In the illustrated example, the lock mechanism L is composed of a cutter 14, a cutter holder 13, and a tightening screw member 44 capable of fixing and holding and detaching the both. That is, since the cutting depth adjusting rod 45 of the moving guide frame 3 is inclined with respect to the guiding rod 46, if the cutter 14 is fixed by the tightening screw member 44 of the cutter holding body 13, The connected adjusting rod 45 cannot move parallel to the cable axis direction, and as a result, the moving guide frame 3 is fixed.

Further, the tightening screw member 44 is loosened and the cutter 14
Is in the free state, the movement guide frame 3 is also in the free state, and can be moved in the cable axis direction.

As described above, according to the lock mechanism L, the cutter 14 can be moved in the cable radial direction and the movement guide frame 3 can be moved in the cable axial direction by a simple operation of screwing and retracting the tightening screw member 44. Can be held and detachably fixed.

The screw member 44 is omitted, and a screw hole communicating with the guide rod 46 of the moving guide frame 3 is provided on the outer peripheral surface of the block body 15a. It is also possible to freely screw a screw member that can be pressed against the guide rod 46 so as to be able to advance and retreat. Even in such a case, the same effect as that of the tightening screw member 44 can be obtained.

When forming the lead-out portion 7 of the cable 1 with this tool, the cable 1 is clamped between the clamping bodies 8 and 9 of the rotary cutting frame 2 as shown in FIGS. The cutter 14 is fixed with its tip reaching the inner semiconductive layer 5 between the insulator 6 and the conductor 4, and
The moving guide frame 3 is fixed by the above-mentioned lock mechanism L so that the distance M between the cutter 60 and the cutter 14 has a desired opening size.
{The cutter 14 is also fixed.} In this state, the handle 12 is gripped and the tool is rotated in the direction of arrow X (FIG. 1).

As a result, as shown in FIG. 19, the insulator 6 is continuously cut in the circumferential direction at a predetermined pitch in the axial direction, and the end surface 1a of the cable 1 is connected to the contact plate portion 60 (not shown). Protruding to.

In the illustrated example, a case is shown in which only the insulator 6 is cut while leaving the internal semiconductive layer 5 around the conductor 4.
It is also desirable to make the tip of the cutter 14 reach the outer peripheral surface of the conductor 4 and also cut the internal semiconductive layer 5.

That is, with this tool, as described above,
Since the rigidity of the holding members 8 and 9 is large, and the backlash of the guide rollers 17 contacting with the cable 1 does not occur, the cutting depth of the cutter 14 can be maintained with high precision, and as a result, the thin inner half can be maintained. The conductive layer 5 can be accurately peeled off.

When the inner semiconductive layer 5 is left around the conductor 4, the inner semiconductive layer 5 is scraped off with a knife or the like after completion of the terminal cutting to expose the conductor 4.

Thereafter, as shown in FIG. 21, when the leading end of the cable 1 comes into contact with the contact plate 60, the moving guide frame 3 is fixed, so that it is not possible to further proceed. In this way, the same lead-out dimension as the distance M set as described above is obtained.

Next, the tightening screw member 44 (see FIG. 1) of the lock mechanism L is loosened, the cutter 14 and the moving guide frame 3 are set in a free state, and the cutting is performed again.

As a result, as shown in FIG.
Pushes the contact plate portion 60 while projecting forward, and the moving guide frame 3 moves forward with respect to the rotary cutting frame 2.

Then, along with the movement of the movement guide frame 3, the cutter 14 gradually moves outward in the cable radial direction together with the swinging cylinder 62 slidingly in contact with the cutting depth adjusting rod 45, and the cable 1
A tapered surface is formed on the surface.

Thus, a tapered surface as shown in FIG. 23 is formed, and so-called pencil ring is performed. That is, the inclination angle theta ₂ with respect to the cable axis of the tapered surface is the same as the inclination angle theta ₁ of the cutting depth adjustment rod 45. Therefore, the inclination angle theta ₂ of the tapered surface of the cable 1, by adjusting the inclination angle theta ₁ of the adjusting rod 45 can be set arbitrarily within a predetermined range.

As described above, since the formation of the lead-out portion and the formation of the tapered surface can be switched by a simple operation of the lock mechanism L, the cable terminal cutting work can be performed easily and quickly.

After the cutter 14 has detached from the outer peripheral surface of the cable 1, the bolt rod 28 of the interval adjusting mechanism 11 is unscrewed and loosened, and the tool is pulled forward from the cable 1 so that the tool is removed from the cable 1. Can be easily separated.

Thus, the cable terminal cutting work is completed.

The present invention is not limited to the above-described embodiment.
The design can be freely changed without departing from the gist. For example, a guide rod 10 between the holding members 8 and 9 or an interval adjusting mechanism
It is also preferable that a spring member whose both ends resiliently abut the opposing surfaces of the holding bodies 8 and 9 is externally fitted to the eleventh bolt rod 28.

By doing so, the holding members 8, 9 are separated only by screwing back the bolt rod 28 of the gap adjusting mechanism 11, and when the rotary cutting frame 2 is attached to and detached from the cable 1, It is convenient.

[0095]

Since the present invention is configured as described above,
The following effects are obtained.

The operation for holding and releasing the lock mechanism L can be easily performed at one place. Therefore, both the cutter 14 and the moving guide frame 3 can be switched between the fixed state and the free state by a simple switching operation. As a result, it is possible to quickly switch between the exit of the cable 1 and the formation of the tapered surface,
Can be performed almost as a continuous operation.

Therefore, the time required for cable terminal cutting can be significantly reduced.
