Thereby, the electric wire pressing member 11 will be in the state pressed by the urging | biasing force of the elastic member 12 in the direction (downward) which protrudes toward the covered electric wire D from the clamping part 1a. At the position where the flange portion 11b of the wire pressing member 11 is received by the stepped portion 109a, the lower surface of the electric wire pressing member 11 and the lower surface of the holding portion 1a substantially coincide with each other, and the holding surface 11a of the electric wire pressing member 11 has a coating H. It can contact or be in close contact with the peeled and exposed electric wire (conductor) D1.

In the case of a linear covered electric wire as shown in FIG. 23, tightening is performed until the covered electric wire D hits the holding surface of the holding portion 1a (until the holding surface 11a of the wire pressing member 11 coincides with the holding surface of the holding portion 1a). By doing so, the cutting edge of the coating stripping cutter 5 is inserted into the coated electric wire to a depth slightly shorter than the thickness of the coating H, that is, until the outer peripheral surface of the conductor passes. When the covered wire stripper 200 is rotated in the circumferential direction about the covered wire D as an axis, the cover H of the covered wire D is peeled off while being cut by the outer peripheral surface of the conductor by the cover stripping cutter 5. .
Further, when the guide blade 8a is bitten into the coating H of the coated electric wire D, the coated electric wire coating / stripping device 200 is rotated about the coated electric wire D, so that the coated electric wire coating / stripping device 200 becomes the guide blade 8a. The covering H of the covered electric wire D is spirally peeled off by the covering stripping cutter 5 while being moved obliquely and being moved in the right direction. Moreover, when the electric wire from which the coating has been peeled reaches the electric wire pressing member 11, the electric wire pressing member 11 protrudes by the biasing force of the elastic member 12, contacts the exposed electric wire D1, and holds the electric wire from which the coating has been peeled off. . Since the wire pressing member 11 is located near the side of the coating stripping cutter 5, the wire from which the coating H has been peeled is immediately held by the wire pressing member 11, so that the wire and the wire pressing member after the coating peeling is performed. The backlash between the members 11 is extremely small, and the continuous peeling of the coating H can be performed satisfactorily. Moreover, since the exposed electric wire D1 is not damaged, the disconnection resulting from the damage can be eliminated.

The base end 51c of the adapter 50 is not exposed from the concave groove 53 when the adapter 50 is in a position where the adapter 50 is superposed on the holding portion 2a or a position protruding forward, so that the holding member main body 1 and the movable holding member 2 (adapter (Including the state in which 50 is polymerized)), it does not get in the way when the covered electric wire D is sandwiched. Further, when the adapter 50 is in a position where it is overlapped on the clamping part 2 a, the through hole 52 matches the through hole 7 of the guide member 8 provided in the clamping part 2 a of the movable clamping member 2. Thereby, even if it is a case where the adapter 50 is used, like the covering electric wire covering stripper 100 mentioned above, it is possible to go in and out to the position where the guide blade 8a bites into the covering H of the covering electric wire D.

The structure for enabling the guide member 8 having the guide blade 8a to appear and retract with respect to the movable holding member 2 is substantially the same as that described in the above-described covered electric wire covering stripper 100. In addition, in this covered electric wire coating stripper 200, in order to correspond to the case where an adapter is used, the rotation range of the switching lever and the stroke in which the guide member protrudes and retracts are different from those of the above-described covered electric wire coating stripper 100. Yes.
The movable clamping member 2 includes a through-hole 7 having a quadrangular cross-section that is located at the center of one side of the clamping part 2a and extends from the upper surface of the clamping part to the lower circular hole 130 and the guide hole 131. A guide member 8 is provided in the through hole 7 so as to be able to appear and retract by a cam mechanism. The guide member 8 has a guide blade 8a provided so as to be inclined at a predetermined angle with respect to the axis of the covered electric wire D held on the upper surface.

  As a projecting structure of the guide member 8, an L-shaped bracket is formed in which a through hole 7 is formed at one side center portion of the sandwiching portion 2 a of the movable sandwiching member 2 and communicated with the through hole 7 at the center and fixed to the lower portion of the guide member 8. 35 and a space 37 for accommodating the spring 36. A circular hole 130 and a guide hole 131 that is long in the lateral direction are provided on one side of the circular hole 130 at the lower portion of the movable clamping member 2. In the through hole 7, a guide member 8 having a guide blade 8a on the upper portion is accommodated so as to be slidable in the vertical direction. A cam plate 132 is rotatably provided in the circular hole 130 by a shaft 39 provided at the center of the movable holding member 2. A spring 36 is provided on the upper surface of the L-shaped metal fitting 35 fixed to the lower portion of the guide member 8 with a screw. The spring 36 urges the L-shaped bracket 35 downward, and the guide member 8 protrudes into the circular hole 130 at the lower portion thereof and engages with the cam surface 133 of the cam plate 132 disposed in the circular hole 130. It is supposed to be.

The rectangular through-hole 7 that accommodates the guide member 8 is configured by applying a side plate 34 to a side surface of a vertically provided cutout hole and fixing it with a screw. And the guide member 8 is provided in this through-hole 7 so that raising / lowering is possible. The upper surface of the side plate 34 has a shape that matches the shape of the arcuate sandwiching surface of the sandwiching portion 2a, and is fixed to the sandwiching portion 2a so that the top surface matches. The guide blade 8a is formed to be inclined at a predetermined angle with respect to the axis of the covered electric wire D. The angle of the guide blade 8a is an angle suitable for spiral peeling, for example, about 70 degrees with respect to the axial direction of the covered electric wire D.
A cam surface 133 is formed around the upper surface of the circular cam plate 132. As the cam plate 132 rotates, the cam surface 133 in contact with the guide member 8 changes, so that the guide member moves up and down. The cam surface 133 is continuous with the concave surface 133a forming the first step surface, the first convex surface 133b forming the second step surface formed so as to be continuous with the concave surface 133a, and the first convex surface 133b. And a second convex surface 133c that forms a third step surface that is higher than the first convex surface. The concave surface 133a, the first convex surface 133b, and the second convex surface 133c are formed so as to be continuous in a curved surface shape. A portion of the cam plate 132 that transitions from the first convex surface 133b to the second convex surface 133c is a rounded surface (curved surface), and the movement of the guide member that moves along the cam surface is favorable. The guide member 8 moves up and down by the rotation of the cam plate 132.

  Specifically, the guide member 8 moves up and down in three stages by the rotation of the cam plate 132. The height of the second convex surface 133c is higher by the thickness of the adapter 50 that is superimposed on the clamping surface of the clamping part. Thereby, the guide blade 8a slightly protrudes from the clamping surface 51b of the adapter 50 superposed on the clamping part.

  A shaft 39 having a threaded portion 39a at the upper end is inserted into the center hole 138 of the cam plate 132 from the lower part of the center hole. The shaft 39 is inserted into the insertion hole 35 a of the L-shaped bracket 35 fixed to the guide member 8. The upper threaded portion 39a is screwed and fixed in a screw hole provided in the clamping portion 2a of the movable clamping member 2. The cam plate 132 is rotatably provided on the shaft 39. A spring 36 is provided so as to enclose the shaft 39 in the space 37 and to be placed on the upper surface of the L-shaped bracket 35 fixed to the guide member 8. The L-shaped metal fitting 35 fixed to the guide member 8 is always urged downward by a spring 36 to abut (press) the guide member against the cam surface 133 of the cam plate 132. The guide member 8 moves up and down by the rotation of the cam plate 132.

  A circular hole 130 and a guide hole 131 for a switching lever are provided in the lower part of the movable clamping member 2. The guide hole 131 is for rotating a switching lever provided on the side wall of the cam plate 132 for a predetermined stroke, for example, about 90 degrees, in order to rotate the cam plate 132 rotatably provided in the circular hole 130. It is. The guide hole 131 is formed in an L shape. The switching lever 40 passes through the guide hole 131 and is fixed by being screwed into the side wall of the cam plate 132. By moving the switching lever 40 along the guide hole 131 within a predetermined stroke range, the cam surface 133 of the cam plate 132 that comes into contact with the guide member 8 changes, so that the guide member 8 is switched to the three-step vertical position. It is possible. Specifically, when the switching lever 40 is moved to the right end of the guide hole 131, the cam plate 132 rotates to the right, and the guide member 8 comes into contact with the concave surface 133a of the cam. In this state, the guide member 8 is urged downward by the action of the spring 36 via the L-shaped bracket 35, so that the lower surface of the guide member 8 is pressed against the concave surface 133 a of the cam, and the guide blade 8 a It immerses in the through-hole 7 (refer FIG. 12). When the switching lever 40 is moved to the left of the guide hole 131 and is positioned approximately in the middle of the stroke, the guide member 8 comes into contact with the first convex surface 133b of the cam plate 132. In this state, the lower surface of the guide member 8 is pushed up by the first convex surface 133 b, the L-shaped bracket 35 is pushed up against the spring 36, and the guide blade 8 a protrudes from the upper end of the through hole 7. The protruding guide blade 8a bites into the covering H of the covered electric wire D (see FIG. 17). Since the guide blade 8a is inclined with respect to the axis of the covered electric wire D, the guide blade 8a is guided to advance in the spiral direction when the covered electric wire stripping device is rotated around the covered electric wire D. The traveling direction with respect to the axial direction of the covered electric wire D at this time is referred to as a covered electric wire peeling traveling direction.

  When the adapter 50 is used, the switching lever 40 is moved to the left end of the guide hole 131 and is positioned at the left end of the stroke. In this state, the guide member 8 comes into contact with the second convex surface 133c of the cam plate 132. In this state, the lower surface of the guide member 8 is pushed up by the second convex surface 133c, and the L-shaped metal fitting 35 is pushed up against the spring 36. The guide blade 8a is moved from the upper end of the through hole 52 of the adapter 50. Protruding. The protruding guide blade 8a bites into the covering H of the thin coated wire D '(see FIG. 17). Since the guide blade 8a is inclined with respect to the axis of the small-diameter covered electric wire D, the guide blade 8a is guided to advance in the spiral direction when the covered electric wire stripping device is turned around the covered electric wire D.

  The covered wire stripper 200 of this embodiment has the above-described structure. When the covered electric wire D is clamped, the operation handle 23 is turned counterclockwise and the operating gear 21 is rotated counterclockwise to open the movable clamping member 2 with respect to the clamping member main body 1 so as to be clamped with the clamping portions 1a of both clamping members. The covered electric wire D is inserted between the clamping surfaces of the part 2a. Next, by turning the operation handle 23 clockwise and pushing up the base 2c of the movable clamping member 2 by the action portion 21c via the drive gear 22 and the operating gear 21, the movable clamping member 2 is tightened with respect to the clamping member main body 1. The covered electric wire D is pushed up by the movable holding member 2, and the covered electric wire is held. At the time of holding the covered electric wire, the covered electric wire D is elastically held in a state where the electric wire pressing member 11 is pushed up against the elastic member 12, and the covering electric wire D is provided for the holding member main body 1. The cutter 5 is in a state of being cut into the covered electric wire to a depth at which the covering H is peeled off. In this state, the sheathed wire sheath stripper rotates in the circumferential direction around the sheathed wire D with the operation handle 23 as the operation portion, so that the sheathed wire sheath stripper rotates in the direction of the blade edge of the sheath stripping cutter 5. To do. When the coated wire coating stripper rotates once, the coating stripping cutter 5 strips the coating H by the width of the cutter and performs partial annular stripping of the coating.

  Next, by moving the switching lever 40 to the left along the guide hole 131, the convex surface 133b of the cam surface 133 pushes up the guide member 8 against the spring 36, and the guide blade 8a protrudes from the holding portion 2a. The protruding guide blade 8a slightly bites into the outer periphery of the covering H of the covered covered electric wire D. When the adapter 50 is used, the second convex surface 133c of the cam surface 133 pushes up the guide member 8 against the spring 36 and moves the guide blade 8a beyond the holding portion 51 of the adapter 50 by further moving leftward. . The protruding guide blade 8a slightly bites into the outer periphery of the covering H of the thin covered electric wire D 'sandwiched.

After such an operation, the operating handle 23 is rotated about the axis of the covered electric wire D, whereby the covering stripping cutter 5 is guided in the direction of the guide blade 8a, and the covering electric wire covering stripper is in the spiral direction. A spiral continuous peeling of the coating is performed, which moves and the coating H is continuously peeled off. Then, when a gap is formed between the exposed electric wire D1 and the electric wire pressing member 11 on the side where the covering H of the covered electric wire D is peeled off, the electric wire pressing member 11 automatically protrudes by the urging force of the elastic member 12. , Abuts against the exposed electric wire D1. As a result, there is no backlash between the coated wire stripping device and the coated wire D, the coating H can be peeled off satisfactorily, and the exposed wire D1 is damaged during or after peeling. Nor.
After completion of the peeling operation of the desired length of the covering H, the guide lever 8 comes into contact with the concave surface 133a of the cam surface 133 by returning the switching lever 40 to the right side, and the guide member 8 is pushed down by the spring 36 and lowered. The guide blade 8a is in a retracted state (non-projecting state). By turning the operation handle 23 at that position, the coating stripping cutter 5 cuts off the coating H. Thereby, the coating peeling operation is completed.
Then, the operation handle 23 is rotated in the direction in which the holding member is opened, the movable holding member 2 is opened from the holding member main body 1, and the covered electric wire covering stripper is removed from the covered electric wire D from which the covering H has been peeled off.

Note that, as described above, the covered wire sheath stripper is moved in the axial direction of the covered wire D by the guide member 8, the cam member (the cam plate 32 and the cam surface 33), the biasing means (spring 36), and the switching lever 40. The peeling work selecting means is configured to select whether to perform continuous peeling that progresses to the above or partial annular peeling that does not proceed in the axial direction of the covered electric wire D.
