There is no restriction | limiting in particular as the slider 52, What is necessary is just to be able to comprise the 2nd lower board 5 in the direction of the 1st lower board 3 so that separation is possible.

Next, the operation of the cable stripper 1 of the present embodiment configured as described above will be described.
First, when the six core wires 55 exposed from the end of the multi-core cable are cut obliquely, the first upper plate 7, the second upper plate 11, the third upper plate 16 in FIGS. And the upper surface of the 1st lower board 3 and the 2nd lower board 5 is open | released by opening the 4th upper board 19, and in this state, the lower groove 4 of each front end holding groove 9 of the 1st holding part 10 and 2nd By passing each core wire 55 between the lower groove 6 of each rear end gripping groove 21 of the grip portion 22 and closing the first upper plate 7 and the fourth upper plate 19, the front end side of each core wire 55 is set to the first side. The grip part 10 is gripped, and the rear end side of each core wire 55 is gripped by the second grip part 22.

  Next, the first upper blade support plate 27 of the core wire cutting part 26 is rotated about the point A, the first lower blade support plate 29 is rotated about the point B, and the first upper blade support plate 27 and By adjusting the first lower blade support plate 29 to a predetermined angle, the first upper blade 32 and the first upper blade 32 of each cutting blade 34 attached to the first upper blade support plate 27 and the first lower blade support plate 29. The lower blade 33 is slid along the guide grooves 24, 23 while being guided by the upper blade guide grooves 24 and the lower blade guide grooves 23, and the first upper blade 32 and the first lower blade 33 of each cutting blade 34. Are positioned at positions in the upper blade guide grooves 24 and the lower blade guide grooves 23 corresponding to the first upper blade support plate 27 and the first lower blade support plate 29, respectively.

  Here, the first lower blade support plate 29 of the core wire cutting portion 26 is rotated about the point B by rotating the adjusting screw 35 ′, so that the rotation is rotated via the connecting plate 50 and the connecting pin 51. The second lower blade support plate 41 of the coating stripping portion 38 also rotates around the point D, following the first lower blade support plate 29. Thereby, the angle of the second lower blade support plate 41 is adjusted to an angle corresponding to the first upper blade support plate 27, and the second lower blade of each stripping blade 46 attached to the second lower blade support plate 41. 45 slides along the guide groove 23 while being guided by each lower blade guide groove 23, and the second lower blade 45 of each peeling blade 46 corresponds to each lower blade guide groove corresponding to the second lower blade support plate 41. 23, the first lower blade support plate 29 is fixed to the first lower plate 3, and the blade fixing screw 35 is tightened to fix the interval between the blades.

  Then, as shown in FIG. 4, by inserting the lock pin 36 at the end of the first lower blade support plate 29 into the lock hole 37 at the end of the first upper blade support plate 27, the first of each cutting blade 34. The upper blade 32 and the first lower blade 33 are opposed to each other, and the first upper blade support plate 27 is fixed to the second upper plate 11 by the blade fixing screw 35.

  Similarly, by inserting the lock pin 36 at the end of the second lower blade support plate 41 into the lock hole 37 at the end of the second upper blade support plate 39, the second upper blade 44 of each stripping blade 46 and the second 2 The lower blade 45 is made to face, and the second upper blade support plate 39 is fixed to the third upper plate 16 by the blade fixing screw 35.

  Then, as shown in FIGS. 4, 5, and 7, the second upper plate 11 is closed and each core wire 55 is sandwiched between the first upper blade 32 and the first lower blade 33 of each cutting blade 34. By cutting each core wire 55 and closing the third upper plate 16, the core wire 55 is covered between the second upper blade 44 and the second lower blade 45 of each stripping blade 46. Make a notch.

  In this case, as shown in FIG. 7, the second upper plate 5 and the third upper plate 16 have the main body portions 13, 18 in the support frames 12, 17 against the urging force of the spring 15 against the support rod 14. Accordingly, the first upper blade 32 and the first lower blade 33 of each cutting blade 34 and the second upper blade 44 of each stripping blade 46 and the second upper blade 44 are moved vertically to the direction of the first lower plate 3. The two lower blades 45 can be aligned with each other from the vertical direction.

  In this state, as shown in FIGS. 1 and 2, the coating is removed from each core wire 55 by moving the second lower plate 5 and the fourth upper plate 19 in a direction away from the first lower plate 3. The conductor of each core wire 55 can be exposed.

  In the cable stripper 1 of the present embodiment configured as described above, when the six core wires 55 exposed from the tip of the multi-core cable are cut into a predetermined length and the coating is peeled off, Since the six cores 55 can be cut simultaneously and the covering can be peeled off simultaneously, the work of cutting the cores 55 into a predetermined length and stripping the covering from the cores 55 can be performed efficiently. .

  Further, each core wire 55 is passed between the front end gripping groove 9 of the first gripping portion 10 of the main body 2 and the rear end gripping groove 21 of the second gripping portion 22, and the first upper plate 7 and the fourth upper plate. By closing the second upper plate 5 with the 19 closed, the six core wires 55 can be simultaneously cut to a predetermined length. Further, the third upper plate 16 is closed and the second lower plate 5 and By moving the fourth upper plate 19 in the direction away from the first lower plate 3, the coating can be peeled off from each core wire 55 cut to a predetermined length, which is influenced by the skill level of the operator. Even if it is an inexperienced operator, each core wire 55 can be cut | disconnected to predetermined length, and a coating | coated can be stripped from each core wire 55 now.

  When the six core wires 55 are cut to the same length and the coating is peeled off from each of the core wires 55, the first upper blade support plate 27 of the core wire cutting portion 26 is shown in FIG. And the 1st lower blade support plate 29 is positioned in the position orthogonal to the length direction of the main-body part 2, The 2nd upper blade support plate 39 and the 2nd lower blade support plate 41 of the coating stripping part 38 follow this, and Similarly, it is only necessary to position at a position orthogonal to the length direction of the main body 2.

In the above description, the present invention is applied to the case where the six core wires 55 are cut and the coating is peeled off. However, the cutting operation of the number of the core wires 5 other than six and the stripping operation of the coating are performed. The present invention may be applied to.
Further, in the above description, the main body portion 2 is provided with the six front end gripping grooves 9, the rear end gripping groove 21, the lower blade guide groove 23, and the upper blade guide groove 24. These may be set to 5 or less and 7 or more.
