[0067] (Definition of the term)

[0068] In this specification, the terms "upstream side" and "downstream side" are defined based on the direction in which the coating is separated from the core wire.

Figure 21 A flowchart illustrating an example of the coating stripping method of the first embodiment.

[0075] like Figure 2 As shown, the suture stripper 1 of the first embodiment includes a first guide body 2, a blade body 3, and a second guide body 4.

[0076] like Figure 4 As shown, the first guide body 2 defines the first channel PH and guides the coated line W. (As indicated...) Figure 1 As shown, the first channel PH includes an inlet Pa and an outlet Pb. Inlet Pa is the inlet port of the first channel PH where the covered wire W is introduced (in other words, the inlet port for the covered wire). Outlet Pb is the outlet port for the core wire W2 (refer to...) Figure 4 The discharge port is located at the first channel PH. The first guide body 2 is composed of an assembly of multiple components. For example, the first guide body 2 includes a first component 21 and a second component 24.

[0077] like Figure 4 As shown, the blade 3 separates the coated wire W disposed in the first channel PH into a coating layer W1 and a core wire W2. The coated wire W is, for example, an electrical wire, the coating layer W1 is, for example, an electrically insulating layer, and the core wire W2 is, for example, an electrically conductive wire. The blade tip 33 of the blade 3 is exposed within the first channel PH. The blade tip 33 of the blade 3 is disposed between the inlet Pa and the outlet Pb of the first channel PH. Figure 4 In the recorded example, the distance between the blade tip 33 and the outlet Pb is less than the distance between the blade tip 33 and the inlet Pa.

[0078] like Figure 5 As shown, the second guide body 4 defines the second channel PJ, guiding the coating layer W1 separated from the core wire W2. (As...) Figure 6 As shown, the second channel PJ includes an inlet 4a, which is adjacent to the blade body 3. The function of the inlet 4a is to guide the coating layer W1, separated from the core wire W2, from the first channel PH into the second channel PJ. The second guide body 4 can be composed of a single component or an assembly of multiple components.

[0079] exist Figure 2 In the example described, the second guide body 4 has a guiding part 41a, a turning part 44a, and a receiving part 46a.

[0080] The guide section 41a guides the coating layer W1, which has separated from the core wire W2, toward the turning section 44a. The guide section 41a defines a first moving channel PJ1 for the movement of the coating layer W1.

[0081] The turning unit 44a reverses the movement direction of the coating layer W1. More specifically, the turning unit 44a reverses the movement direction of the coating layer W1 so that the movement direction of the coating layer W1 is the opposite of the first direction DR1 (in other words, the direction having a movement component in the fourth direction DR4, which is opposite to the first direction DR1). In the peeling of the coating wire W, the relative movement of the coating layer W1 separated from the core wire W2 relative to the cutter body 3 generally has a movement component in the first direction DR1. Conversely, the turning unit 44a reverses the movement of the coating layer W1 separated from the core wire W2 relative to the cutter body 3 so that the relative movement of the coating layer W1 separated from the core wire W2 relative to the cutter body 3 has a movement component in the fourth direction DR4, which is opposite to the first direction DR1.

[0082] The receiving part 46a receives the coating layer W1 from the turning part 44a. The receiving part 46a defines a second moving channel PJ2 for the movement of the coating layer W1.

[0083] The coated wire stripper 1 of the first embodiment includes a second guide 4 that guides the coated layer W1 separated from the core wire W2. The second guide 4 has a receiving portion 46a. By receiving the coated layer W1 in the receiving portion 46a, the movement of the coated layer W1 separated from the core wire W2 can be stabilized. For example, when the first guide 2 and the blade 3 rotate around the coated wire W, the centrifugal force generated by the rotation can prevent the coated layer W1 separated from the core wire W2 from moving erratically. Furthermore, it can prevent the coated layer W1 separated from the core wire W2 from becoming entangled with the coated wire W, the coated wire stripper 1, or other tools. In addition, the second guide 4 has a turning portion 44a that changes the direction of movement of the coated layer W1 to a direction opposite to the first direction DR1. In this way, the turning portion 44a prevents the coated layer W1 from advancing further beyond the guide portion 41a in the first direction DR1. As a result, interference between the coating layer W1 and the receiving portion 46a that houses the coating layer W1 and components positioned further along the first direction DR1 than the guide portion 41a (e.g., the base 55, the first gear 51, etc. described below) can be prevented. Furthermore, the turning portion 44a has the function of reducing the tension acting on the coating layer W1 as it separates from the core wire W2 (in other words, the force acting on the extending direction of the coating layer W1). More specifically, the tension acting on the coating layer W1 is reduced by the coating layer W1 colliding with the turning portion 44a. As a result, during the peeling operation, the coating layer W1 is prevented from splitting into multiple pieces, and the split pieces are prevented from falling from the receiving portion 46a. Furthermore, the collision of the coating layer W1 with the turning portion 44a promotes the spiraling of the coating layer W1 (refer to [reference needed] if necessary). Figure 10 As a result, on the downstream side of the turning section 44a, the coating layer W1 no longer increases.

[0084] Next, refer to Figures 1 to 20 The following describes any additional configurations that can be used in the coated wire stripper 1 of the first embodiment.

[0085] (Guidance section 41a)

[0086] exist Figure 6 In the described example, the guide portion 41a (more specifically, the guide member 41) has a bottom end portion 42 (in other words, the upstream end portion) configured to cover the blade body 3. For example... Figure 6 As shown, the bottom end portion 42 of the guide portion 41a may also have a semi-cylindrical shape. In other words, the blade body 3 may also be covered by the bottom end portion 42 having a semi-cylindrical shape.

[0087] exist Figure 5 In the described example, the guide portion 41a (more specifically, the guide member 41) has a top portion 43 (in other words, the downstream end) which is disposed opposite to the steering portion 44a. Figure 7 As shown, the top end portion 43 of the guide portion 41a may also have a semi-cylindrical shape.

[0088] exist Figure 5 In the described example, the steering part 44a is positioned downstream of the top end 43 of the guide part 41a. Furthermore, the third end of the top end 43 of the guide part 41a towards the DR3 side is open. Figure 5 As shown, the top end 43 of the guide portion 41a can also be inserted into the receiving portion 46a.

[0089] The guide portion 41a (more specifically, the guide member 41) may also have a first mounting portion 411, mounted on the steering portion 44a. Alternatively, or additionally, the guide portion 41a (more specifically, the guide member 41) may also have a second mounting portion 413, mounted on the first guide body 2 (see reference 44a). Figure 7 ).

[0090] exist Figure 5 In the described example, the guiding part 41a and the steering part 44a are separate entities. More specifically, the guiding part 41a is composed of a guiding member 41, and the steering part 44a is composed of a steering member 44; the guiding member 41 and the steering member 44 are separate entities. Alternatively, the guiding part 41a and the steering part 44a may also be integrally formed.

[0091] exist Figure 5 In the described example, when viewed along a direction perpendicular to both the extension direction of the first channel PH (in other words, the first direction DR1) and the extension direction of the guide portion 41a (in other words, the third direction DR3) (hereinafter referred to as the "fifth direction DR5"), the angle α1 formed between the extension direction of the first channel PH and the extension direction of the guide portion 41a is, for example, a specified angle of 70 degrees or more and 110 degrees or less. When viewed along the fifth direction DR5, the angle α1 formed between the extension direction of the first channel PH and the extension direction of the guide portion 41a may also be 90 degrees.

[0092] (Steering unit 44a)

[0093] exist Figure 4 In the described example, the steering part 44a (more specifically, the steering member 44) has a collision surface 45 that collides with the coating W1, which is separated from the core wire W2. Figure 4 In the described example, the collision surface 45 is an inclined surface that is inclined relative to both the extending direction of the guide portion 41a (in other words, the third direction DR3) and the extending direction of the receiving portion 46a (in other words, the second direction DR2). The collision surface 45 transforms the motion component of the coating layer W1 moving toward the collision surface 45 in the third direction DR3 into the motion component of the coating layer W1 in the second direction DR2.

[0094] exist Figure 5 In the described example, the collision surface 45 is disposed downstream of the top end 43 of the guide portion 41a. Furthermore, the collision surface 45 faces the open end disposed on the third-direction DR3 side of the top end 43. Figure 4 In the example described, the steering unit 44a (more specifically, the steering member 44) turns the direction of movement of the coating layer W1 so that the direction of movement of the coating layer W1 is substantially opposite to the first direction DR1 (more specifically, the fourth direction DR4).

[0095] like Figure 5 As shown, the collision surface 45 may also be disposed inside the receiving portion 46a (more specifically, the receiving member 46). Furthermore, the collision surface 45 may also be disposed outside the guiding portion 41a (more specifically, the guiding member 41).

[0096] Compared to the inner surface of the guide portion 41a, the collision surface 45 preferably has high sliding characteristics. Furthermore, compared to the inner surface of the receiving portion 46a, the collision surface 45 preferably has high sliding characteristics. High sliding characteristics can be achieved by using a material with high sliding characteristics, or by surface treatment.

[0097] The steering member 44 may also have a cover 445 that blocks the open end of the upstream side of the receiving portion 46a. Alternatively, or additionally, a cover member CP, different from the steering member 44, may also block the open end of the upstream side of the receiving portion 46a. Further alternatively, the upstream end of the receiving portion 46a may not be an open end but a locked end. In other words, the locked end of the receiving portion 46a and the cylindrical portion 47 of the receiving portion 46a may also be integrally formed.

[0098] exist Figure 5In the described example, the steering part 44a is a separate entity from the guide part 41a and the receiving part 46a. More specifically, the steering part 44a is composed of a steering member 44, which is a separate entity from the guide part 41a and the receiving part 46a. Alternatively, the steering part 44a may be integrally formed with the guide part 41a and / or the receiving part 46a.

[0099] (Containing part 46a)

[0100] exist Figure 4 In the described example, the receiving portion 46a receives the coating layer W1 separated from the core wire W2. Preferably, the receiving portion 46a has a cylindrical portion 47 for receiving the coating layer W1 separated from the core wire W2. Furthermore, the cylindrical portion 47 is preferably cylindrical in shape. When the receiving portion 46a has a cylindrical portion 47 (more specifically, a cylindrical portion) for receiving the core wire W2, even when centrifugal force acts on the coating layer W1, it can prevent the coating layer W1 from moving erratically in a direction away from the central axis C1 of the first channel PH.

[0101] The receiving portion 46a (more specifically, the cylindrical portion 47) is preferably configured to prevent the coating layer W1 from moving in a direction away from the central axis C1 of the first channel PH downstream of the turning portion 44a. In this case, during the peeling operation, the coating layer W1 can be prevented from splitting into multiple small pieces due to the centrifugal force acting on the coating layer W1, and the split small pieces can be prevented from falling from the receiving portion 46a.

[0102] As a comparative example Figure 8 This illustrates an example where the distance between the tip Wa1 of the coating layer W1 and the central axis C1 (in other words, the rotational central axis of the first guide relative to the coating line) increases as peeling progresses. In this case, as peeling progresses, the centrifugal force acting on the tip Wa1 of the coating layer W1 increases, increasing the risk of the coating layer W1 splitting into multiple flakes.

[0103] exist Figure 5 In the described example, the receiving portion 46a (more specifically, the central axis C2 of the receiving portion 46a) and the first channel PH (more specifically, the central axis C1 of the first channel PH) are substantially parallel. This configuration prevents the receiving portion 46a from moving the coating layer W1 away from the central axis C1 of the first channel PH. As a result, during the peeling operation, the coating layer W1 is prevented from splitting into multiple flakes, and the split flakes are prevented from falling from the receiving portion 46a.

[0104] exist Figure 5 In the described example, the receiving portion 46a is composed of a receiving member 46. The receiving portion 46a has a bottom end portion 48 (in other words, the upstream end) and a top end portion 49 (in other words, the downstream end). Figure 9As shown, the receiving portion 46a (more specifically, the receiving member 46) may also have a hole 46h. Figure 5 In the example described, the guide portion 41a is configured to traverse the hole portion 46h.

[0105] exist Figure 4 In the described example, viewed along the fifth direction DR5, the channel from the inlet Pa of the first channel PH through the guide portion 41a and the receiving portion 46a to the top portion 49 (in other words, the downstream end) of the receiving portion 46a (in other words, the channel formed by the movement channel of the coating layer W1 before separation from the core wire W2 and the movement channel of the coating layer W1 after separation from the core wire W2) has a U-shape. This U-shaped channel prevents the coating layer W1 from advancing further in the first direction DR1 beyond the guide portion 41a. Furthermore, after the peeling operation is completed (in other words, after the coating layer W1 is completely separated from the coating wire W), the completely separated coating layer W1 is stably held by the guide portion 41a, the turning portion 44a, and the receiving portion 46a. Therefore, it prevents the completely separated coating layer W1 from falling from the receiving portion 46a.

[0106] exist Figure 4 In the described example, the second channel PJ of the second guide body 4 includes an outlet 4b. The function of this outlet 4b is to serve as a retrieval outlet for removing the coating layer W1, completely separated from the coating line W, from the receiving portion 46a after the peeling operation is completed. Figure 4 In the described example, outlet 4b is an opening located at the end of the receiving portion 46a on the second direction DR2 side. This outlet 4b can also be locked by a cover member. In other words, the second guide 4 can also have a cover member to block outlet 4b.

[0107] (First moving channel PJ1 and second moving channel PJ2)

[0108] exist Figure 10 In the example described, the guide portion 41a defines a first movement channel PJ1 for the movement of the covered layer W1, and the receiving portion 46a defines a second movement channel PJ2 for the movement of the covered layer W1. Each of the first movement channel PJ1 and the second movement channel PJ2 constitutes a part of the aforementioned second channel PJ.

[0109] exist Figure 10In the described example, the width of the second moving channel PJ2 (more specifically, the diameter of the second moving channel PJ2) is greater than the width of the first moving channel PJ1 (more specifically, the diameter of the first moving channel PJ1) to prevent the coating layer W1 from spiraling in the first moving channel PJ1, while the coating layer W1 spirals in the second moving channel PJ2. By preventing the coating layer W1 from spiraling in the first moving channel PJ1, the coating layer W1 can move smoothly from the first moving channel PJ1 to the second moving channel PJ2. Furthermore, by spiraling the coating layer W1 in the second moving channel PJ2, the coating layer W1 is tightly disposed in the second moving channel PJ2. Therefore, the length of the receiving portion 46a can be shortened.

[0110] like Figure 10 As shown, the receiving portion 46a (more specifically, the receiving member 46) may also be made of a transparent member. Furthermore, the guiding portion 41a (more specifically, the guiding member 41) may also be made of a transparent member. The receiving portion 46a may also be made of polycarbonate.

[0111] (First Guide Body 2)

[0112] exist Figure 11 In the described example, the first guide body 2 has a first member 21 and a second member 24. The second member 24 is movable relative to the first member 21. More specifically, the second member 24 is movable relative to the first member 21 to approach the first member 21, and the second member 24 is movable relative to the first member 21 to move away from the first member 21.

[0113] The first component 21 and the second component 24 cooperate to form a first channel PH. More specifically, the first component 21 has a first groove 22 extending along a first direction DR1, and the second component 24 has a second groove 25 extending along the first direction DR1. Figure 12 As shown, when the first guide 2 is in the closed state (in other words, when the first member 21 and the second member 24 are close to each other), the first groove 22 and the second groove 25 cooperate to define the first channel PH of the covered line W. Figure 4 In the example described, the blade 3 is mounted on the first component 21. Furthermore, in... Figure 4 In the example described, the second guide body 4 (more specifically, the guide part 41a) is mounted on the first component 21.

[0114] like Figure 12As shown, it is preferable to form threads (more specifically, helical protrusions 22p and 25p) on the surfaces of the first groove 22 and the second groove 25, transforming the relative rotation of the first guide 2 relative to the coated line W into relative movement of the coated line W relative to the first guide 2 in the first direction DR1. The length of the first channel PH is, for example, 5 cm or more, 7 cm or more, or 9 cm or more. By lengthening the length of the first channel PH, it is easy to straighten the coated line W which tends to be curved. Furthermore, by lengthening the length of the first channel PH, the length of the thread in the direction along the first direction DR1 can be lengthened. By lengthening the length of the thread in the direction along the first direction DR1, the relative rotation of the first guide 2 relative to the coated line W can be effectively transformed into relative movement of the coated line W relative to the first guide 2 in the first direction DR1 (in other words, the propulsion force for the relative movement of the coated line W relative to the first guide 2 in the first direction DR1 can be sufficiently ensured).

[0115] exist Figure 11 In the described example, the first guide body 2 has an operating member 26 that changes the spacing between the first member 21 and the second member 24. Furthermore, the operating member 26 has an operating portion (e.g., an operating ring 261) operable by a remote operating tool and a screw 263 screwed into at least one of the first member 21 and the second member 24. The screw 263 may also have a threaded portion 263a screwed into the first member 21 and a reverse-threaded portion 263b screwed into the second member 24.

[0116] exist Figure 11 In the described example, if the operating member 26 (more specifically, the operating ring 261) is operated in the first operating direction MR1, the gap between the first member 21 and the second member 24 is reduced. On the other hand, in Figure 12 In the example described, if the operating member 26 (more specifically, the operating ring 261) is operated in the second operating direction MR2, the interval between the first member 21 and the second member 24 increases.

[0117] exist Figure 12 In the described example, the first guide 2 has at least one guide rod 27 that guides the second member 24 to move relative to the first member 21. Figure 12 In the example described, the guide rod 27 includes a first guide rod 27a and a second guide rod 27b, each of which is arranged parallel to the screw 263.

[0118] exist Figure 13 In the described example, the first guide body 2 has a support block 28 that supports the first component 21 and the second component 24. Figure 13In the example described, the support block 28 supports the first component 21 and the second component 24 via the screw 263 and the guide rod 27.

[0119] exist Figure 6 In the described example, the receiving portion 46a (more specifically, the receiving member 46) is disposed on the outside of the first guide 2, and the first guide 2 is disposed on the outside of the receiving portion 46a (more specifically, the receiving member 46). In this case, compared to the case where the first guide 2 is disposed on the inside of the receiving portion 46a, the size of the receiving portion 46a can be made more compact. Furthermore, in Figure 6 In the described example, the receiving portion 46a (more specifically, the receiving member 46) is disposed on the outside of the first guide 2, so the covering layer W1 received in the receiving portion 46a will not become entangled with the first guide 2. Figure 6 In the described example, when the first member 21 and the second member 24 are in contact, the inner diameter D1 of the accommodating portion 46a is more than 1.5 times and less than 3 times the diameter D2 of the first channel PH. Furthermore, in Figure 6 In the example described, the length L1 of the accommodating portion 46a is more than 0.5 times and less than 2 times the length of the first channel PH.

[0120] (Blade Body 3)

[0121] exist Figure 14 In the described example, the blade body 3 has a mounting portion 31 and a blade tip 33 mounted on the first guide body 2 (more specifically, the first member 21). For example... Figure 15 As shown, the blade tip 33 can also have an arc shape.

[0122] exist Figure 14 In the described example, the blade tip 33 is tilted so as to approach the second member 24 in the first direction DR1. More specifically, the distance between the end 33e of the blade tip 33 on the first direction DR1 side and the second member 24 is less than the distance between the end 33f of the blade tip 33 on the fourth direction DR4 side and the second member 24.

[0123] (Rotating part RT, base 55, and power transmission component 57)

[0124] exist Figure 4 In the example described, the coated wire stripper 1 includes a rotating part RT, a base 55, and a power transmission component 57.

[0125] The rotating part RT rotates relative to the coated line W. More specifically, the rotating part RT rotates relative to the coated line W about the central axis C1 of the first channel PH. Figure 16 An example of the rotating part RT is shown. The rotating part RT includes a first guide 2 and a cutter body 3. Figure 16 Not shown), guide section 41a ( Figure 16 Not shown), Steering unit 44a ( Figure 16 (Not shown), and receiving portion 46a. Additionally, the rotating portion RT may also include the first gear 51 described below. Furthermore, the rotating portion RT may also include a connecting member 53 that links the first gear 51 and the first guide 2 (more specifically, support block 28).

[0126] like Figure 4 As shown, the base 55 rotatably supports the rotating part RT. More specifically, the base 55 supports the rotating part RT so that it can rotate about the central axis C1 of the first channel PH. Figure 17 An example of a base 55 is shown. The base 55 defines an internal space SP that accommodates at least a portion of the power transmission member 57. More specifically, the base 55 includes a frame 56 that defines the internal space SP and accommodates at least a portion of the power transmission member 57.

[0127] exist Figure 18 In the described example, base 55 supports a first gear 51 and a second gear 59 meshing with the first gear 51. More specifically, the first gear 51 is supported by base 55 so that it can rotate about the central axis C1 of the first channel PH. Furthermore, the second gear 59 is supported by base 55 so that it can rotate about an axis parallel to the aforementioned central axis C1. Figure 18 In the described example, both the first gear 51 and the second gear 59 are housed within the internal space SP of the frame 56. The first gear 51 may also include a first portion 51a defining a side opening OP and a second portion 51b (more specifically, a switch member) defining a switch side opening OP. The first portion 51a has external teeth and is generally U-shaped. The second portion 51b has external teeth and is rotatably connected to the first portion 51a, and is generally arm-shaped. When the second portion 51b is in the open position, the connecting sleeve SV can also be inserted into the inside of the first gear 51 from the outside through the side opening OP.

[0128] exist Figure 19 In the described example, the power transmission member 57 receives rotational driving force from the outside. The power transmission member 57 may also include a shaft 58, which receives rotational driving force from the outside. Figure 19 In the example described, shaft 58 is supported by base 55.

[0129] like Figure 18 As shown, the power transmission component 57 may also include a second gear 59 meshing with the first gear 51. Figure 18 In the example described, the second gear 59 is fixed to the shaft 58.

[0130] The power transmission member 57 converts the rotational driving force received from an external source (e.g., a remote-operated tool) into a relative rotation of the rotating part RT relative to the base 55. Assume the top end of the remote-operated tool is connected to the shaft 58, and the bottom end is connected to the output shaft of a power tool. In this case, if the power tool is rotated, the rotational driving force is input from the output shaft of the power tool to the shaft 58 via the remote-operated tool. When the rotational driving force is input to the shaft 58, the second gear 59 fixed to the shaft 58 rotates, and the first gear 51 meshing with the second gear 59 rotates. If the first gear 51 rotates, the first guide 2 fixed to the first gear 51 rotates around the coating layer W via the connecting member 53. Thus, the coating layer W1 separates from the core wire W2 via the blade body 3 fixed to the first guide 2. It is worth noting that in... Figure 4 In the described example, the coating layer W1, separated from the core wire W2, is housed in the receiving portion 46a (more specifically, the cylindrical portion 47). Therefore, even when the first guide body 2 is rotated at high speed using a power tool, the coating layer W1 is prevented from moving erratically in a direction away from the central axis C1 of the first channel PH. As a result, during the peeling operation, the coating layer W1 is prevented from splitting into multiple pieces due to the centrifugal force acting on the coating layer W1, and the split pieces are prevented from falling from the receiving portion 46a.

[0131] exist Figure 4 In the described example, the second guide 4 (more specifically, the guide portion 41a, the steering portion 44a, and the receiving portion 46a) prevents the coating layer W1, separated from the core wire W2 by the cutter body 3, from moving beyond the base 55 (more specifically, the frame 56) in the first direction DR1. More specifically, the steering portion 44a rotates the coating layer W1, separated from the core wire W2 by the cutter body 3, in a direction away from the base 55 (more specifically, the frame 56).

[0132] exist Figure 4 In the example described, the entire guide section 41a, the entire steering section 44a, and the entire housing section 46a are positioned on the fourth direction DR4 side more than the base 55 (more specifically, the frame 56).

[0133] (Sleeve support component 6)

[0134] like Figure 20 As shown, the coated wire stripper 1 may also include a sleeve support member 6 to support the connecting sleeve SV that connects the core wire W2 of the coated wire W to the core wires of other coated wires. Figure 20 In the described example, the sleeve support member 6 is included in the rotating part RT. In other words, the sleeve support member 6 and the first guide 2 rotate simultaneously around the covering line W.

[0135] The casing support member 6 may also have a first end support member 61 supporting one end of the connecting casing SV and a second end support member 66 supporting the other ends of the connecting casing SV. Figure 20 In the described example, the first end support member 61 is disposed at the outlet Pb of the first channel PH defined by the first guide 2. In this case, the core wire W2, separated from the coating layer W1, is smoothly inserted into the connecting sleeve SV supported by the first end support member 61. Furthermore, the separation of the coating layer W1 from the core wire W2 and the insertion of the core wire W2 into the connecting sleeve SV can be performed simultaneously.

[0136] In the first embodiment, the sleeve support member 6 may be omitted. Furthermore, in the coated wire stripper 1 of the first embodiment, the core wire W2 separated from the coated layer W1 may be configured as any cylindrical member housed outside the connecting sleeve. This cylindrical member may be fixed to the base 55 or to the rotating part RT.

[0137] (Method for peeling the covering thread)

[0138] Next, refer to Figures 1 to 21 The method for peeling the coating line according to the first embodiment will be described.

[0139] In the liner stripping method of the first embodiment, a liner stripper is used to perform the stripping operation on the liner. The liner stripper used in the liner stripping method of the first embodiment may be the liner stripper 1 of the first embodiment, or it may be other liner strippers.

[0140] In the first step, ST1, the coated thread stripper is prepared. Step ST1 is the preparation process. For example... Figure 20 As shown, the preparation process (first step ST1) prepares a coated wire stripper that includes a first guide body 2 and a blade body 3 mounted on the first guide body 2. Figure 20 (Not shown), second guide body 4. The second guide body 4 includes a guide part 41a ( Figure 20 Not shown), Steering unit 44a ( Figure 20 (Not shown), and receiving portion 46a. The coated wire stripper prepared in the preparation process (first step ST1) may also include a rotating portion RT, a base 55, and a power transmission member 57. Furthermore, the coated wire stripper prepared in the preparation process (first step ST1) may also include a sleeve support member 6.

[0141] The components of the first guide body 2, the cutter body 3, the second guide body 4, the guide part 41a, the turning part 44a, the accommodating part 46a, the rotating part RT, the base 55, the power transmission member 57, and the sleeve support member 6 have already been described, so the description of their structure will not be repeated.

[0142] In the second step ST2, the coated wire W is positioned in the first channel PH of the first guide 2. The second step ST2 is a positioning process. The positioning process (second step ST2) may also include inserting the end of the coated wire W into the first channel PH. In this case, the end of the coated wire W is stripped in a later step than the second step ST2. Alternatively, the positioning process (second step ST2) may also include positioning the central portion of the coated wire W in the first channel PH. In this case, the central portion of the coated wire W is stripped in a later step than the second step ST2.

[0143] In the third step ST3, the coated wire W is separated into a coating layer W1 and a core wire W2 by the blade 3. The third step ST3 is the separation process. The separation process (third step ST3) is performed by rotating the first guide 2 relative to the coated wire W disposed in the first channel PH (see reference). Figure 4 (Arrow AR1). This relative rotation can also be achieved by converting the rotational driving force received by the power transmission member 57 from outside the coated thread stripper (e.g., the rotational driving force received by the power transmission member 57 from a remote operating tool) into a relative rotation of the rotating part RT relative to the base 55. Alternatively, this relative rotation can also be achieved directly by the operator rotating the first guide 2 about the coated thread W.

[0144] In the fourth step ST4, the coating layer W1, separated from the core wire W2, is guided to the turning section 44a. The fourth step ST4 is a guiding process. The guiding process (fourth step ST4) is performed using the guiding section 41a. Figure 6 In the described example, the guide portion 41a has a bottom end portion 42 facing the blade body 3 and a top end portion 43 opening toward the turning portion 44a (see reference). Figure 10 The coating layer W1, separated from the core wire W2, passes through the bottom end 42 (reference). Figure 6 ) The guide section 41a is introduced, and the tip section 43 (see reference) Figure 10 The coating W1 discharged from the guide section 41a collides with the steering section 44a.

[0145] exist Figure 10 In the described example, the guiding process (fourth step ST4) is performed while preventing the coating layer W1 from spiraling away from the core wire W2. In the guiding process (fourth step ST4), preventing the coating layer W1 from spiraling away prevents it from blocking the guiding section 41a. In other words, by preventing the coating layer W1 from spiraling away, the movement of the coating layer W1 from the guiding section 41a to the receiving section 46a can proceed smoothly.

[0146] In the fifth step ST5, the movement direction of the coating layer W1 is changed by the turning unit 44a. The fifth step ST5 is a turning process. The turning process (fifth step ST5) includes the turning unit 44a changing the movement direction of the coating layer W1 so that the movement direction of the coating layer W1 is reversed relative to the first direction DR1.

[0147] In step ST6, the receiving portion 46a receives the coating layer W1 from the turning portion 44a. Step ST6 is the receiving process. Through the receiving process, the coating layer W1 is received in the receiving portion 46a (see reference). Figure 10 ).

[0148] The receiving process (sixth step ST6) can also be included in the receiving section 46a to spiral the coating layer W1. By spiraling the coating layer W1 in the receiving section 46a, the coating layer W1 no longer increases in size.

[0149] Additionally, the stripping method of the coated wire in the first embodiment may also include a step of inserting the core wire W2 separated from the coated layer W1 into a connecting sleeve SV for connecting the core wire W2 separated from the coated layer W1 and other core wires (hereinafter referred to as the "insertion step") (see reference). Figure 4 The insertion process is performed concurrently with the separation process (step 3 ST3), the guiding process (step 4 ST4), the turning process (step 5 ST5), and the receiving process (step 6 ST6). In other words, separating the coating layer W1 from the core wire W2 and inserting the core wire W2 into the connecting sleeve SV are performed simultaneously.

[0150] In the stripping method of the first embodiment, the turning portion 44a changes the moving direction of the coating layer W1 to a direction reversed relative to the first direction DR1. This prevents the coating layer W1 from advancing further along the first direction DR1 beyond the guide portion 41a. Consequently, it prevents the coating layer W1 from interfering with components positioned further along the first direction DR1 than the guide portion 41a. Furthermore, in the stripping method of the first embodiment, by accommodating the coating layer W1 by the receiving portion 46a, the movement of the coating layer W1 separated from the core wire W2 can be stabilized.

[0151] This utility model is not limited to the first embodiment or its variations. Obviously, within the scope of the technical concept of this utility model, the first embodiment or its variations can be appropriately modified or changed. Furthermore, any constituent element can be omitted in the first embodiment or its variations.

[0152] [Industry availability]

[0153] Using the wire stripper or wire stripping method of this invention can stabilize the process of the coating layer separating from the core wire. Therefore, it is very useful for operators who use the wire stripper or wire stripping method or for manufacturers of wire strippers.
