[0011] Specific embodiments related to the present invention are described below with reference to the drawings.

[0012] Fig. 1 is a sectional view taken along a longitudinal direction of an electric wire in a terminal processing apparatus according to the embodiment. Fig. 2 is a sectional view along II-II in Fig. 1.

[0013] As in Fig. 1, the terminal processing device 100 according to the embodiment includes a blade 11, a regulating member 13, a guide 15, and a rotating mechanism 17. In addition, the terminal processing device 100 includes an electric wire holding chuck 19.

[0014] The terminal processing device 100 is a device that processes one terminal of the electric wire 1. The electric wire 1 processed by the terminal processing device 100 is an electric wire, such as a high-frequency cable or the like, used for transmitting high-speed digital signals, but is not limited thereto.

[0015] As in Fig. 2, the electric wire 1 in the example is a two-core cable having two core wires 3, each covered by an insulator 2. In the electric wire 1, foils (outer members) 4, which are shield conductors, cover around the two core wires 3, and further, its outer peripheral side is covered by a covering (not shown in the figure). The foil 4 is, for example, a metal foil tape in which aluminum foil or the like is attached to a resin tape. The foil is provided on the core wire 3 by longitudinal arrangement or winding. The terminal processing device 100 forms a cut line in a part of the foil 4 exposed from the covering around an entire circumference of the foil 4 at a terminal of the electric wire 1.

[0016] Fig. 3 is a sectional view taken along the longitudinal direction of the electric wire at the processing point of the electric wire in the terminal processing device. Fig. 4 is a perspective view of the processing point of the electric wire in the terminal processing device.

[0017] As in the Fig. 3 and Fig. As shown in Figure 4, the blade 11 is arranged with a blade tip 21 directed toward the electric wire 1 and is configured to create a cutting line in the foil 4 of the electric wire 1. It is preferable that the blade 11 is double-edged, and a material of the blade 11 is, for example, an alloy tool steel (SKD11) that is superior in terms of wear resistance. The blade 11 is attached to the regulating element 13 with a bolt 22 (see Fig. 1).

[0018] The regulating element 13 is arranged adjacent to the blade 11. The regulating element 13 has a contact surface 25 at its tip, and the contact surface 25, which contacts the outer periphery of the electric wire 1, regulates the depth of the cutting line of the blade 11 against the foil 4 of the electric wire 1.

[0019] The regulating member 13 has one side that is a flat surface 26 along a radial direction of the electric wire 1, and the blade 11 is arranged to be superimposed on the flat surface 26. The blade 11 superimposed on this flat surface 26 is fixed by a bolt 22. The other side, opposite to the flat surface 26, of the regulating member 13 is an inclined surface 27 that slopes away from the flat surface 26 in a direction away from the electric wire 1. Consequently, the regulating member 13 is shaped to taper toward the electric wire 1, and the contact surface 25 to come into contact with the electric wire 1 is arranged near the blade 11. A clearance between the blade 11 and the regulating member 13 is set to, for example, 0.15 mm. In the regulating element 13, the corners 28 and 29 on both sides of the contact surface 25 are chamfered in an arc shape.This suppresses the generation of scratches on the foil 4 of the electric wire 1 when the contact surface 25 of the regulating element 13 contacts the electric wire 1.

[0020] For example, stainless steel (SUS) is preferred as a material for the regulating element 13. When the regulating element 13 is made of stainless steel, there are no metal deposits, such as plating, on the foil 4 of the electric wire 1, and there is also less chipping than in the case of a plastic material. Furthermore, the contact surface 25 of the regulating element 13 is mirror-polished to reduce friction with the foil 4 of the electric wire 1, which further suppresses the formation of scratches on the foil 4 of the electric wire 1.

[0021] The blade 11, which is attached to the regulating element 13, protrudes with its blade tip 21 from the contact surface 25 of the regulating element 13. The protrusion size D of the blade tip 21 is set to be smaller than a thickness of the foil 4 of the electric wire 1. Accordingly, the regulating element 13 regulates the depth of the cutting line of the blade 11 against the electric wire 1 to be less than the thickness of the foil 4.

[0022] The guide 15 is arranged on the opposite side of the blade 11 and the regulating member 13 with respect to the electric wire 1. The guide 15 has a guide surface 31 that contacts the electric wire 1. The guide 15 has one side that is a flat surface 32 along the radial direction of the electric wire 1, and the other side opposite the flat surface 32 is an inclined surface that slopes away from the flat surface 32 toward the direction away from the electric wire 1. Accordingly, the guide 15 is shaped to taper toward the electric wire 1. The guide 15 has its guide surface provided at a position corresponding to the location between the blade 11 and the regulating member 13 in the longitudinal direction of the electric wire 1. The corners 34 and 35 on both sides of the guide surface 31 of the guide 15 are chamfered in an arc shape.This suppresses the generation of scratches on the foil 4 of the electric wire 1 when the guide surface 31 of the guide 15 contacts the electric wire 1.

[0023] As a material for the guide 15, stainless steel (SUS), for example, is preferred. When the guide 15 is made of stainless steel, there are no metallic deposits, such as plating, on the foil 4 of the electric wire 1, and there is also less chipping than in the case of a plastic material. Furthermore, the guide surface 31 of the guide 15 is mirror-polished to reduce friction with the foil 4 of the electric wire 1, which further suppresses the formation of scratches on the foil 4 of the electric wire 1.

[0024] As in Fig. 1, the rotating mechanism 17 has a rotating shaft 41 rotating about the axis Ax, a connecting member 43 fixed to the rotating shaft 41 with a bolt 42, a supporting member 45 fixed to the connecting member 43 with a bolt 44 and supported by the rotating shaft 41, and a pair of movable blocks 46 and 47 supported by the supporting member 45.

[0025] The movable blocks 46, 47 are supported so as to be movable in the radial direction of the electric wire 1. A biasing member 48, structured by a coil spring or the like, is provided on the support member 45. The movable blocks 46, 47 are biased toward the electric wire 1 by the biasing member 48.

[0026] A regulating member 13, to which the blade 11 is attached, is fixed to one of the movable blocks 46 with a fixing bolt 49. This allows the blade 11 to move in the radial direction of the electric wire 1. Furthermore, the regulating member 13, in conjunction with the knife 11, moves in the radial direction of the electric wire 1. Furthermore, the blade 11 and the regulating member 13 are biased against the electric wire 1 by an elastic force of the biasing member 48. Therefore, the blade 11 cuts into the foil 4 of the electric wire 1, and the contact surface 25 of the regulating member 13 contacts the outer peripheral surface of the electric wire 1.

[0027] A guide 15 is fixed to the other movable block 47 with a tightening screw 49. This allows the guide 15 to move in the radial direction of the electric wire 1. Furthermore, the guide 15 is biased toward the electric wire 1 by the elastic force of the biasing member 48. Therefore, the guide surface 31 of the guide 15 contacts the outer peripheral surface of the electric wire 1, and the pressure of the electric wire 1 exerted by the blade 11 and the regulating member 13 is received by the guide 15.

[0028] The blade 11, the regulating member 13 and the guide 15 provided on the rotating mechanism 17 rotate around an axis of the electric wire 1 by the rotation of the rotating axis 41 of the rotating mechanism 17.

[0029] The electric wire holding chuck 19 is arranged on an opposite side of the regulating member 13 with respect to the blade 11. The electric wire holding chuck 19 holds the electric wire 1 at a position in close proximity to the cutting position of the electric wire 1 by the blade 11. The electric wire 1 held by this electric wire holding chuck 19 is arranged along an axis Ax of the rotation axis 41 of the rotation mechanism 17, and the electric wire 1 is passed between the blade 11 and the regulating member 13 and the guide 15.

[0030] To process the terminal of the electric wire 1 with the terminal processing device 100 having the above-described configuration, the electric wire 1 is first held by the electric wire holding chuck 19. At this time, the electric wire 1 is passed between the blade 11 and the regulating member 13 and the guide 15, and arranged along the axis Ax of the rotation axis 41 of the rotation mechanism 17.

[0031] Accordingly, the electric wire 1 is clamped between the blade 11 and the regulating element 13 and the guide 15. As a result, the tip of the blade 21 of the blade 11 cuts into the foil 4 of the electric wire 1, and the contact surface 25 of the regulating element 13 and the guide surface 31 of the guide 15 contact the outer peripheral surface of the electric wire 1.

[0032] Then, when the rotation axis 41 of the rotating mechanism 17 is rotated, the blade 11 and the regulating member 13 and the guide 15 rotate one lap or more around the electric wire 1. As a result, the foil 4 of the electric wire 1 is cut along an entire circumference by the blade 11, with the blade tip 21 having cut into the foil 4 of the electric wire 1.

[0033] At this time, since the projection amount D of the blade tip 21 projecting from the contact surface 25 of the regulating member 13 is adjusted by the regulating member 13 to be smaller than the thickness of the foil 4, and the cutting depth into the foil 4 is limited to the thickness of the foil 4 or less, it is not possible for the foil 4 of the electric wire 1 to be cut too deeply.

[0034] When the blade 11 cuts the foil 4 of the electric wire 1, the pressing force of the electric wire 1 pressed by the blade 11 and the regulating member 13 is supported by the guide surface 31 of the guide 15, which is provided at a position corresponding to the position between the blade 11 and the regulating member 13. This reduces the fluctuation of the electric wire 1 during the cutting of the foil 4 by the blade 11.

[0035] Subsequently, the electric wire 1, whose foil 4 has been cut off over the entire circumference, is removed from the holding chuck 19 of the electric wire.

[0036] In this way, according to the terminal processing device 100 of the above embodiment, it is possible to cut into the foil 4 of the electric wire 1 with one blade 11 while regulating excessive cutting by the regulating member 13. Therefore, compared with the case of using a pair of blades, the terminal of the electric wire 1 can be processed with high processing quality even if the requirement for the mounting accuracy of the blade 11 is relaxed, while suppressing the generation of cut fragments, which is suitable for automating terminal processing. Furthermore, it can reduce the equipment cost and labor hours for replacing the blade 11.

[0037] Furthermore, during the cutting of the film 4 of the electric wire 1 by the blade 11, the guide 15 receives the pressure of the electric wire 1 pressed by the blade 11 and the regulating member 13. Since the fluctuation of the electric wire 1 during the cutting of the film 4 is suppressed and the film 4 is cut with high positional accuracy, a cutting margin of the film 4 can be shortened. As a result, for example, a twirling length of the electric wire 1 can be shortened, the frequency characteristics can be improved, and a higher communication speed can be achieved.

[0038] Furthermore, the electric wire holding chuck 19, which holds the electric wire 1 on the side opposite the regulating member 13 with respect to the blade 11, is installed. By holding the electric wire 1 by the electric wire holding chuck 19 provided on the side opposite the regulating member 13 with respect to the blade 11, the fluctuation of the electric wire 1 during the cutting operation of the blade 11 into the film 4 of the electric wire 1 can be reduced. This stabilizes the trajectory of the blade 11 with respect to the electric wire 1, resulting in an improvement in processing quality.

[0039] In the above embodiment, although the case where the film 4 of the electric wire 1, which is a multi-core cable having two core wires 3, is cut was illustrated, the terminal processing device 100 is applicable not only to the terminal processing of the electric wire 1 of multi-core cables but also to the terminal processing of the electric wire 1 of a single-core cable having one core wire 3.

[0040] Next, modified examples of the connection processing device will be described. The same components as in the above embodiment are denoted by the same reference symbols, and their explanations will be omitted. (Modification example 1)

[0041] Fig. 5 is a cross-sectional view taken along the longitudinal direction of the electric wire at the processing site of the terminal processing apparatus of Modification Example 1. Fig. 6 is a perspective view of the processing site of the electric wire in the terminal processing apparatus of Modification Example 1.

[0042] As in the Fig. 5 and Fig. As shown in Fig. 6, the guide 15 in Modification Example 1 has a recess 51. The recess 51 accommodates the electric wire 1. The electric wire 1 accommodated in the recess 51 is regulated in its radial movement.

[0043] In Modification Example 1, since the electric wire 1 is received and held in the recess 51 of the guide 15, the fluctuation of the electric wire 1 during the cutting operation of the blade 11 into the film 4 of the electric wire 1 can be reduced. As a result, the trajectory of the blade 11 becomes stable, leading to an improvement in processing quality. (Modification example 2)

[0044] Fig. 7 is a cross-sectional view taken along the longitudinal direction of the electric wire at the processing site of the terminal processing apparatus of Modification Example 2.

[0045] As in Fig. 7, in Modification Example 2, it is equipped with a single-edged blade 11, and the regulating member 13 is arranged on the back surface 11a of the single-edged blade 11.

[0046] According to Modification Example 2, the blade tip 21 of the blade 11 can be brought closer to the regulating member 13. Since the regulating member 13 can maintain the position closer to the cutting position of the foil 4 of the electric wire 1 by the blade 11, the processing quality can be further improved. Particularly, in the case where the distance from the axis Ax to the foil 4 changes along the longitudinal direction of the electric wire 1 in the electric wire such as a twisted wire, it is possible to improve the accuracy of the cutting depth by bringing the blade tip 21 as close as possible to the regulating member 13 using a single blade 11, and the distance from the axis Ax to the foil 4 at the position of the blade tip 21 and the distance from the axis Ax to the foil 4 at the position of the regulating member 13 are almost made consistent. (Modification example 3)

[0047] Fig. 8 is a cross-sectional view taken along the longitudinal direction of the electric wire at the processing site of the terminal processing apparatus of Modification Example 3.

[0048] As in Fig. 8, in Modification Example 3, it is equipped with a pair of regulating members 13, and the regulating member 13 is arranged on both sides of the blade 11. Each of the regulating members 13 is arranged so that the blade 11 is overlapped on the flat surface 26. Since the pair of regulating members 13 are arranged in parallel in the longitudinal direction of the electric wire 1, even if the electric wire 1 inserted into the terminal processing device 100 is horizontally inclined, the inclination is corrected when pressed by these regulating members 13, and the accuracy of the cutting depth of the blade tip 21 is improved. It should be noted that the blade 11 may be a single-edged or a double-edged one.

[0049] According to Modification Example 3, since both sides of the cutting position of the foil 4 of the electric wire 1 by the blade 11 can be held by the regulating members 13, the processing quality can be further improved. (Modification example 4)

[0050] Fig. 9 is a longitudinal sectional view of an electric wire in a terminal processing apparatus according to Modification Example 4. Fig. 10 is a cross-sectional view taken along the line XX in Fig. 9.

[0051] As in the Fig. 9 and Fig.As shown in FIG. 10, in Modification Example 4, a blade 61 made of roller blades is provided. The blade 61 made of roller blades is formed into a disc shape, and a blade tip 71 is provided on its outer periphery. In the same manner as the blade 11, a disc-shaped regulating member 63 and a disc-shaped guide 65 are provided. The regulating member 63 is formed slightly smaller in diameter than the blade 61, whereby the blade 61 protrudes over the entire circumference from the outer periphery of the regulating member 63 by the protrusion amount D, which is equal to or smaller than the thickness of the foil 4 of the electric wire 1.

[0052] In Modification Example 4, bearings 76 and 77 are provided in the movable blocks 46 and 47, respectively. In the bearing 76 of the movable block 46, the centers of the blade 11 and the regulating member 63 are fixed by a bolt 79. Accordingly, the blade 11 and the regulating member 63 are rotatably supported by the movable block 46 via the bearing 76. The center of the guide 65 is also fixed by the bolt 79 in the bearing 76 of the movable block 47. Accordingly, the guide 65 is rotatably supported by the movable block 47 via the bearing 76.

[0053] In Modification Example 4, by the rotation of the rotation axis 41 of the rotating mechanism 17, the blade 61 and the regulating member 63 and the guide 65 pivot during the rotation around the axis of the electric wire 1. As a result, the foil 4 of the electric wire 1 is cut along an entire circumference by the blade 61, and the blade tip 71 cuts into the foil 4 of the electric wire 1.

[0054] According to Modification Example 4, when the blade 61, the regulating member 63, and the guide 65 are rotated around the axis of the electric wire 1 by the rotating mechanism 17, the blade 61, which is made of a roller blade, rotates around its own axis. In other words, since the blade 61 sequentially cuts into the foil 4 of the electric wire 1 along the circumferential direction, local wear due to the blade cutting into specific areas of the foil 4 of the electric wire 1 can be reduced, resulting in a longer service life.

[0055] It should be noted that the present invention is not limited to the above-described embodiments and can be modified or improved as appropriate. Other aspects, such as the materials, shapes, dimensions, number, placement, etc. of each component in the above-described embodiments, can be arbitrary and are not limited as long as they can achieve the present invention.

[0056] Here, we summarize and list aspects of the terminal processing apparatus and the terminal processing method according to the above-described embodiments of the invention as [1] to [7].

[0057] [1] In a terminal processing device (100) for an electric wire (1) in which an outer periphery of a core wire (3) is covered by an outer member (film 4), the device includes: a blade (11, 61) movable in a radial direction of the electric wire (1) and applying a cutting line in the outer element (foil 4), a regulating element (13, 63) which moves in conjunction with the blade (11, 61) in the radial direction of the electric wire (1) and limits the depth of the cutting line made by the blade (11, 61), a guide (15, 65) arranged on the side opposite the blade (11, 61) and the regulating element (13, 63) with respect to the electric wire (1) and absorbing the compressive force on the electric wire (1) by the blade (11, 61) and the regulating element (13, 63), and a rotating mechanism (17) that rotates the blade (11, 61), the regulating element (13, 63) and the guide (15, 65) about an axis of the electric wire (1).

[0058] The guide (15, 65) is provided at a position corresponding to the position between the blade (11, 61) and the regulating element (13, 63) in a longitudinal direction of the electric wire (1).

[0059] According to the terminal processing device configured as described in [1] above, it is possible to create a cutting line in the outer element of the electric wire with a single blade, while the regulating element prevents excessive cutting. Consequently, compared with using a pair of blades, it is possible to process the electric wire terminal with high processing quality while reducing the generation of cutting fragments. This is suitable for automating terminal processing even when the assembly accuracy requirements of the blades are relaxed. Furthermore, it is possible to keep equipment costs low and further reduce the labor of changing the blades.

[0060] When the outer element of the electrical wire is cut by the blade, the pressure force exerted by the blade and the regulating element on the electrical wire is absorbed by the guide. Therefore, it can suppress the fluctuation of the electrical wire during the cutting of the outer element and cut the outer element with high positioning accuracy, allowing for a shorter play of the outer element after cutting. This can, for example, shorten the untwisting length of the electrical wire, improve frequency characteristics, and promote high-speed communication.

[0061] [2] In the terminal processing device of the above [1], a wire holding chuck (19) is installed to hold the electric cable (1) on the opposite side to the blade (11, 61) with respect to the regulating member (13, 63).

[0062] According to the terminal processing device configured as described above [2], the fluctuation of the electric wire during the cutting operation of the blade into the outer member of the electric wire can be reduced by holding the electric wire with the wire holding chuck provided on the side opposite the regulating member with respect to the blade. This stabilizes the trajectory of the blade with respect to the electric wire, resulting in improved processing quality.

[0063] [3] In the terminal processing device of the above [1], the guide (15) has a recess (51) which receives the electric wire (1) and regulates its radial movement.

[0064] According to the terminal processing device with the configuration of [3] above, since the electric wire is received and held in the groove of the guide, the fluctuation of the electric wire during the cutting operation of the blade into the outer element of the electric wire can be reduced. This stabilizes the trajectory of the blade, resulting in an improvement in processing quality.

[0065] [4] In the terminal processing device of the above [1], the blade (11, 61) is single-edged and the regulating member (13, 63) is arranged on the back of the blade (11, 61).

[0066] According to the terminal processing device having the configuration of the above [4], the processing quality can be further improved because the regulating member can keep the position of the cut in the outer member of the electric wire by the blade at the closest position.

[0067] [5] In the terminal processing device according to the above [1], the regulating member (13, 63) is provided on both sides of the blade (11, 61).

[0068] According to the terminal processing device having the configuration of the above [5], the regulating member can hold both sides of the cutting position in the outer member of the electric wire by the blade, thereby further improving the processing quality.

[0069] [6] In the terminal processing device of the above [1], the blade (61) is a disc-shaped roller blade having a rotatably supported center.

[0070] According to the terminal processing device with the configuration of [6] above, the roller blade serving as the blade rotates around its own axis as the blade, the regulating member, and the guide rotate around the axis of the electric wire through the rotating mechanism. In other words, the blade cuts into the outer element of the electric wire in sequence along the circumferential direction, so that local wear due to the blade cutting into specific areas on the outer element of the electric wire can be reduced, resulting in a longer service life.
