Description

  The present invention relates to a sleeve mounting tool for mounting a sleeve on an electric wire, and a sleeve mounting method.

  Electric wire cutting methods are known. In the electric wire cutting method, the overhead electric wire is divided into a first electric wire and a second electric wire. After necessary work is performed on the grounding side of the overhead electric wire, the cut first electric wire and second electric wire are connected via a sleeve.

  As a related technique, Patent Document 1 describes an overhead wire construction method. In the overhead wire construction method described in Patent Document 1, the covered portion of one covered electric wire is held by one gripper, and the other connecting electric wire is attached in a state where a cylindrical connection sleeve is attached to the core wire of the other covered electric wire. Is covered by the other gripper. After that, by rotating the operation part of the telescopic device with a remote control tool, the distance between one gripper and the other gripper is reduced, and the core wire of one covered wire is opened from one end of the connection sleeve. Is inserted into the connecting sleeve.

  Further, Patent Document 2 describes an inter-column retaining tool for electric wire separation work. The tool described in Patent Document 2 includes an expansion / contraction operation body including an operation shaft and a pair of expansion / contraction rods including inner and outer cylinders connected to both sides of the expansion / contraction operation body. The free ends of the inner cylinders on both sides of the telescopic operation body are each attached with a wire gripping member, and the inner ends of the inner ends of the inner cylinders are respectively formed with female threads. ing. Coaxial screw shafts that symmetrically and simultaneously extend and retract the inner cylinders on both sides of the telescopic operating body are respectively screwed into the female thread portion. When using the tool, the operating shaft is operated and the screw shaft is screwed in a predetermined direction to contract the telescopic rods on both sides of the telescopic operating body. Thus, the distance between the two electric wire holding members is reduced, and the electric wire held by the two electric wire holding members can be loosened to perform a required cutting operation.

In the present specification, members having the same type of function are given the same or similar reference numerals. Further, repeated description of members with the same or similar reference numerals may be omitted.

(Definition of direction)
In this specification, the direction from the second slide bar 5 toward the first slide bar 4 is defined as “first direction”, and the direction from the first slide bar 4 toward the second slide bar 5 is defined as “second direction”. Define.

(First embodiment)
With reference to FIG. 1, the sleeve mounting tool 1A in 1st Embodiment is demonstrated. Fig.1 (a) thru | or FIG.1 (d) are schematic front views of the sleeve mounting tool 1A in 1st Embodiment.

  A sleeve mounting tool 1A according to the first embodiment includes a base 2, a first slide bar 4, a second slide bar 5, a slide bar operation unit 6, a first electric wire gripping tool 7a, and a second electric wire gripping tool. 7b.

  The base 2 includes a sleeve support 21 that supports the sleeve SV and a core support 26 that supports the exposed core WC.

  In the example shown in FIG. 1, a first sleeve support 21 a that supports one end of the sleeve SV is provided at the end of the base 2 in the first direction, and the end of the base 2 in the second direction is provided. A second sleeve support 21b that supports the other end of the sleeve SV is provided. In the example illustrated in FIG. 1, the base 2 includes two sleeve supports (21 a and 21 b). However, the number of sleeve supports included in the base 2 may be one or three or more. . Further, the arrangement of the sleeve supports in the base 2 is not limited to the example shown in FIG. 1 and is arbitrary.

  In the example illustrated in FIG. 1, the first core wire support 26 a that supports the exposed core wire WC <b> 1 of the first electric wire W <b> 1 is provided at the end of the base portion 2 in the first direction, and the second of the base portion 2 is provided. A second core wire support 26b that supports the exposed core WC2 of the second electric wire W2 is provided at the end on the direction side. In the example illustrated in FIG. 1, the base portion 2 includes two core wire supports (26a, 26b). However, the number of the core wire support devices included in the base portion 2 may be three or more. In the example illustrated in FIG. 1, the first core support 26a is disposed on the first direction side of the sleeve support 21 (more specifically, the first sleeve support 21a), and the second core support 26b is arranged on the second direction side of the sleeve support 21 (more specifically, the second sleeve support 21b). In other words, the sleeve support 21 is disposed between the first core support 26a and the second core support 26b.

  In the example illustrated in FIG. 1, the sleeve support 21 and the core support 26 are separate, but the sleeve support 21 and the core support 26 may be integrated. In other words, at least a part of the sleeve support 21 and at least a part of the core support 26 may be shared.

  In addition, when maintaining the alignment state of the center axis of the exposed core WC and the center axis of the sleeve SV is performed using a remote control tool, or when the sleeve support 21 also has the function of the core support, etc. In addition, the core support 26 may be omitted.

  The first slide bar 4 is a member that is arranged on one side of the base 2 (in the first direction side in the example shown in FIG. 1) and is slidable relative to the base 2. The amount of protrusion of the first slide bar 4 from the first direction side end 20a of the base 2 changes by operating the slide bar operation unit 6. In the example illustrated in FIG. 1, when the slide bar operation unit 6 (more specifically, the first slide bar operation unit 6 a) is operated in the first operation direction R <b> 1, the first slide bar 4 is pulled to the base 2 side. . As a result, the protrusion amount of the first slide bar 4 from the first direction side end 20a is reduced. On the other hand, when the slide bar operation unit 6 (more specifically, the first slide bar operation unit 6a) is operated in the second operation direction, the first slide bar 4 moves in a direction protruding from the base 2 side. As a result, the protrusion amount of the first slide bar 4 from the first direction side end portion 20a increases.

  The second slide bar 5 is a member that is disposed on the other side of the base 2 (in the second direction side in the example illustrated in FIG. 1) and is slidable relative to the base 2. The amount of protrusion of the second slide bar 5 from the second direction side end 20b of the base 2 changes by operating the slide bar operation unit 6. In the example illustrated in FIG. 1, when the slide bar operation unit 6 (more specifically, the second slide bar operation unit 6 b) is operated in the first operation direction R <b> 3, the second slide bar 5 is pulled toward the base 2 side. . As a result, the protrusion amount of the second slide bar 5 from the second direction side end 20b is reduced. On the other hand, when the slide bar operation unit 6 (more specifically, the second slide bar operation unit 6b) is operated in the second operation direction R4, the second slide bar 5 moves in a direction protruding from the base 2 side. As a result, the protrusion amount of the second slide bar 5 from the second direction side end 20b increases.

  The slide bar operation unit 6 is an operation unit that slides the first slide bar 4 and the second slide bar 5. In the example illustrated in FIG. 1, the slide bar operation unit 6 includes a first slide bar operation unit 6 a that slides the first slide bar 4, and a second slide bar operation unit 6 b that slides the second slide bar 5. Is provided. Then, the slide movement of the first slide bar 4 and the slide movement of the second slide bar 5 are operated independently. More specifically, when the first slide bar operation unit 6 a is operated, the first slide bar 4 moves relative to the base 2, but the second slide bar 5 does not move relative to the base 2. When the second slide bar operation unit 6 b is operated, the second slide bar 5 moves relative to the base 2, but the first slide bar 4 does not move relative to the base 2.

  In the case where the sleeve mounting tool 1A has a mechanism for selectively transmitting the operating force acting on the slide bar operation unit 6 to either the first slide bar 4 or the second slide bar 5, etc. The first slide bar operation unit 6a and the second slide bar operation unit 6b may be shared.

  The first wire gripper 7a grips the first wire W1 (more specifically, the portion WP1 of the first wire W1 where the core wire is not exposed). The first wire gripper 7 a is connected to the end of the first slide bar 4. Therefore, when the first slide bar 4 slides relative to the base 2, the first wire gripper 7 a moves relative to the base 2. In the example illustrated in FIG. 1, the sleeve mounting tool 1 </ b> A includes a first electric wire gripping tool 7 a. Alternatively, in a shipping state or the like, the sleeve mounting tool 1A may not be provided with the first electric wire gripping tool 7a, and the sleeve mounting tool 1A may be configured to be attached to the existing first electric wire gripping tool.

  The second wire gripper 7b grips the second wire W2 (more specifically, the portion WP2 of the second wire W2 where the core wire is not exposed). The second wire gripper 7 b is connected to the end of the second slide bar 5. Therefore, when the second slide bar 5 slides relative to the base 2, the second wire gripper 7 b moves relative to the base 2. In the example illustrated in FIG. 1, the sleeve mounting tool 1 </ b> A includes a second wire gripping tool 7 b. Alternatively, in a shipment state or the like, the sleeve mounting tool 1A may not be provided with the second electric wire gripping tool 7b, and the sleeve mounting tool 1A may be configured to be attached to an existing second electric wire gripping tool.

  In the sleeve mounting tool 1A in the first embodiment, the slide bar operation unit 6 can operate the slide movement of the first slide bar 4 and the slide movement of the second slide bar 5 independently. Therefore, when inserting the exposed core WC1 of the first electric wire W1 into the sleeve SV, the first slide bar 4 may be moved by a distance shorter than the length of the sleeve SV (FIGS. 1A and 1). (See (b)), when inserting the exposed core WC2 of the second electric wire W2 into the sleeve SV, the second slide bar 5 may be moved by a distance shorter than the length of the sleeve SV (FIG. 1 ( c) and FIG. 1 (d)). For this reason, in the process of connecting the first electric wire W1 and the second electric wire W2 via the sleeve SV, the expansion of the distance between the first electric wire gripping tool 7a and the second electric wire gripping tool 7b is compared with the conventional case. Can be suppressed. As a result, the overall slack of the first electric wire W1 and the second electric wire W2 can be suppressed.

  Further, the base portion 2 of the sleeve mounting tool 1A in the first embodiment may be divided or bent at a substantially central portion. In the case where the division is possible, for example, a concave portion may be provided on one side of the divided body of the base 2, and a convex portion may be provided on the other side of the divided body, and the concave portion and the convex portion may be fixed with a screw after engagement. Alternatively, the shape of the divided body is a shape in which the divided bodies are not separated from each other when force is applied in the first direction and the second direction, and one divided body with respect to the other divided body in the first direction and the second direction. The two split bodies may be made connectable and / or separable by moving in the vertical direction. In addition, when bending is possible, the base 2 may be bent by a hinge or the like so that the base 2 can be bent at a substantially central portion. Since the sleeve mounting tool 1A can be folded in half by being divided or bent at a substantially central portion of the base portion 2, the sleeve mounting tool 1A can be made compact when carrying or storing.

  Further, the end of the exposed core WC tends to spread outward in the radial direction. Conventionally, it has been difficult to insert the exposed core WC into the sleeve opening that is slightly larger than the inner diameter of the exposed core WC. On the other hand, in the first embodiment, when the sleeve mounting tool 1A includes the core support 26, in the step of inserting the exposed core WC into the sleeve SV, between the exposed core WC and the sleeve SV. Can be easily centered. For this reason, the operation | work which inserts the exposed core WC in a sleeve opening part becomes easy. More specifically, the base of the slide bar (the first slide bar 4 or the second slide bar 5) is supported with the sleeve SV supported by the sleeve support 21 and the exposed core WC supported by the core support 26. When retracted to the second side, the exposed core WC is automatically inserted into the sleeve SV. For this reason, the operator can easily insert the exposed core WC into the sleeve SV.

(Sleeve mounting method)
A sleeve mounting method in the first embodiment will be described with reference to FIG.

  In the first step ST1, the sleeve SV is supported by the sleeve support 21. FIG. 1A shows a state after the first step ST1 is executed.

  In the second step ST2, the exposed core of the first electric wire W1 is drawn by pulling the first slide bar 4 toward the base 2 and moving the first electric wire W1 held by the first electric wire gripping tool 7a in the second direction. Line WC1 is inserted into the first end of sleeve SV. FIG. 1B shows a state after the second step ST2 is executed. The second step ST2 is performed, for example, by operating the slide bar operation unit 6 (more specifically, the first slide bar operation unit 6a).

  In 3rd step ST3, the 2nd electric wire W2 grasped by the 2nd electric wire gripping tool 7b is moved in the 2nd direction by moving the 2nd slide stick 5 in the direction projected from the base 2 side. FIG. 1C shows a state after the third step ST3 is executed. The third step ST3 is performed, for example, by operating the slide bar operation unit 6 (more specifically, the second slide bar operation unit 6b).

  In addition, after execution of 3rd step ST3, when the edge part of exposure core wire WC2 and the 2nd direction side edge part of sleeve SV are not mutually opposing, exposure core wire WC2 is used using a remote control tool. May be moved to a position facing the end of the sleeve SV in the second direction. More specifically, the end of the exposed core WC2 may be moved using a remote control tool, and the end is supported by the second core support 26b.

  In the fourth step ST4, the second slide bar 5 is pulled to the base 2 side, and the second electric wire W2 grasped by the second electric wire gripping tool 7b is moved in the first direction, whereby the exposed core of the second electric wire W2 is exposed. Line WC2 is inserted into the second end of sleeve SV. FIG. 1D shows a state after the fourth step ST4 is executed. The fourth step ST4 is performed, for example, by operating the slide bar operation unit 6 (more specifically, the second slide bar operation unit 6b).

  As described above, in the sleeve mounting method according to the first embodiment, the exposed core wire WC1 and the second wire of the first electric wire W1 can be easily operated while suppressing the overall slack of the first electric wire W1 and the second electric wire W2. A sleeve SV can be attached to the exposed core WC2 of the electric wire W2.

(Second Embodiment)
With reference to FIG. 2 thru | or FIG. 7, the sleeve mounting tool 1B in 2nd Embodiment is demonstrated. FIG. 2 is a schematic front view of the sleeve mounting tool 1B according to the second embodiment. FIG. 3 is a schematic front view showing an example of the sleeve support 21 and the core support 26. FIG. 4 is a schematic side view showing an example of the sleeve support 21. FIG. 5 is a schematic side view showing an example of the core support 26. FIG. 6 is a schematic side view showing an example of the wire support 8. FIG. 7 is a schematic two-view diagram illustrating an example of the sleeve cover gripping tool 9. A front view is shown on the left side of FIG. 7, and a side view is shown on the right side of FIG.

  Regarding each member of the second embodiment, members having the same functions as those described in the first embodiment are denoted by the same reference numerals as those used in the first embodiment, and the same reference numerals are used. The repeated description of the members marked with will be omitted.

  A sleeve mounting tool 1B according to the second embodiment includes a base 2, a first slide bar 4, a second slide bar 5, and a slide bar operation unit 6. The sleeve mounting tool 1B may include at least one of the first wire gripping tool 7a, the second wire gripping tool 7b, the wire support tool 8, and the sleeve cover gripping tool 9.

(Base 2)
In the example illustrated in FIG. 2, the base portion 2 includes a rod-shaped portion 20 that extends along the first direction, a sleeve support tool 21, a cord support tool 26, and a slide bar operation unit 6.

  In the example illustrated in FIG. 2, the rod-like portion 20 is a tubular body that includes a first direction side end portion 20 a and a second direction side end portion 20 b, and at least a part thereof is hollow. The rod-shaped part 20 may be made of FRP (made of fiber reinforced plastic) or may be made of metal.

  Subsequently, the sleeve support 21 and the core support 26 will be described with reference to FIGS. 3 to 5.

  In the example illustrated in FIG. 3, the sleeve support 21 includes an attachment portion 23 that is attached to the rod-shaped portion 20 and a support portion 210 that supports the sleeve SV and the like. The mounting portion 23 is provided with a through hole 231 that receives a part of the rod-shaped portion 20 (see FIG. 4). The position of the sleeve support 21 may be adjustable along the first direction with respect to the rod-shaped portion 20. In this case, the position of the sleeve support 21 can be adjusted according to the length of the sleeve SV actually used. Therefore, the versatility of the sleeve mounting tool 1B is improved. Further, the sleeve support 21 may be detachable from the rod-shaped portion 20. In this case, the optimum sleeve support 21 can be attached to the rod-shaped portion 20 in accordance with the diameter of the sleeve SV actually used. Therefore, the versatility of the sleeve mounting tool 1B is improved.

  The support portion 210 is provided with a sleeve support tool operation portion 212 that changes the state of the support portion between a closed state and an open state. When the support portion 210 is in the closed state, the support portion 210 restrains the sleeve SV, and the sleeve SV cannot substantially move relative to the support portion 210. On the other hand, when the support portion 210 is in the open state, the sleeve SV can be placed on the support portion 210 or the sleeve SV can be removed from the support portion 210. In the example illustrated in FIG. 3, the sleeve support tool operating unit 212 is an eye bolt or an eye nut having a through hole that can receive the tip of a remote control tool.

  In the example illustrated in FIG. 3, the support portion 210 includes a first portion 214 that supports the sleeve SV, and a second portion 216 through which the exposed core WC is inserted. In the example illustrated in FIG. 3, the inner surface of the second portion 216 includes a tapered surface 216 a that decreases in diameter toward the first portion 214. Since the second portion 216 includes the tapered surface 216a, the exposed core WC is smoothly inserted into the second portion 216 even when the end of the exposed core WC is widened or bent. Note that the core guide path 217 defined by the inner surface of the second portion 216 and the sleeve receiving portion 215 defined by the inner surface of the first portion 214 communicate with each other. The inner surface of the first portion 214 preferably includes an end surface support surface 214a that faces the end surface of the sleeve SV, and an outer peripheral surface support surface 214b that faces the outer surface of the sleeve SV.

  In the example illustrated in FIG. 3, the core wire support 26 includes a mounting portion 23 attached to the rod-shaped portion 20 of the base portion 2 and a support portion 260 that supports the exposed core wire WC and / or the covered electric wire. In the example shown in FIG. 3, the attachment portion 23 of the core support 26 and the attachment portion 23 of the sleeve support 21 are the same. In other words, the core wire support 26 and the sleeve support 21 share the mounting portion 23. In this case, the attachment portion 23 can be attached to the rod-like portion 20 in a state in which the positional relationship between the sleeve support 21 and the core support 26 is maintained. As in the example illustrated in FIG. 1, the attachment portion of the core wire support 26 and the attachment portion of the sleeve support 21 may be separate.

  The support part 260 is provided with a cord support tool operating part 262 that changes the state of the support part between a closed state and an open state. When the support portion 260 is in the closed state, the support portion 260 restrains the exposed core WC and / or the covered electric wire, and the exposed core WC moves relative to the support portion 260 in a direction perpendicular to the first direction. I can't. On the other hand, when the support portion 260 is in the open state, the exposed core WC and / or the covered electric wire can be placed on the support portion 260, or the exposed core WC and / or the covered electric wire can be removed from the support portion 260. Is possible. In the example illustrated in FIG. 3, the core wire support tool operating unit 262 is an eye bolt or an eye nut having a through hole that can receive the tip of a remote control tool.

  The support portion 260 preferably includes a core wire receiving portion 267 through which the exposed core wire WC and / or the covered electric wire is inserted. Although not illustrated in FIG. 3, the inner surface of the core wire receiving portion 267 may include a tapered surface that decreases in diameter toward the support portion 210 of the sleeve SV. When the core wire receiving portion 267 has a tapered surface, the exposed core wire WC is smoothly inserted into the core wire receiving portion 267.

  In the example illustrated in FIG. 3, a gap G is provided between the support portion 260 of the core wire support tool 26 and the support portion 210 of the sleeve support tool 21. Due to the presence of the gap G, the operator can confirm whether or not the exposed core WC inserted from the core support 26 side has reached the sleeve support 21. In other words, the operator can confirm whether or not the operation of inserting the exposed core WC into the sleeve SV is proceeding smoothly. The gap G may not be present.

  The sleeve support 21 will be further described with reference to FIG. In the example illustrated in FIG. 4, the support portion 210 that supports the sleeve SV includes a first divided body 218a and a second divided body 218b. The interval between the first divided body 218a and the second divided body 218b can be adjusted by operating the sleeve support tool operating unit 212. In the example illustrated in FIG. 4, the first divided body 218a and the second divided body 218b can approach and be separated along a direction (third direction) perpendicular to the first direction. In addition, the state where the space | interval between the 1st division body 218a and the 2nd division body 218b became small respond | corresponds to the closed state where the sleeve SV is restrained, and the 1st division body 218a and the 2nd division body 218b.

This includes “defining the position of the end”). The second electric wire support 8b supports the end portion of the second electric wire W2 after cutting the electric wire ("supporting the end portion" includes "defining the position of the end portion"). )

  The third wire support 8c is disposed on the opposite side of the base 2 from the second wire support 8b. In other words, the third wire support 8 c is configured to be positioned below the base 2 when the second wire support 8 b is positioned above the base 2. By moving the second electric wire W2 using a remote control tool, the position of the end of the second electric wire W2 is supported by the third electric wire support 8c from the position supported by the second electric wire support 8b. Assume a change to a position. In this case, the end of the first electric wire W1 supported by the first electric wire support 8a and the end of the second electric wire W2 supported by the third electric wire support 8c are suitably distributed (for example, up and down ).

  Alternatively or additionally, the first wire support 8 a and / or the second wire support 8 b may be rotatable about the longitudinal axis of the base 2. In this case, by rotating the first wire support 8a or the second wire support 8b about the longitudinal axis of the base 2, the end of the first wire W1 supported by the first wire support 8a, The end portion of the second electric wire W2 supported by the two-wire support tool 8b can be distributed (for example, distributed vertically).

The sleeve cover gripping tool 9 grips the sleeve cover SC disposed along the first electric wire W1 or the second electric wire W2. The sleeve cover gripping tool 9 is attached to any one of the first slide bar 4, the second slide bar 5, the first wire gripping tool 7a, and the second wire gripping tool 7b, for example.

  When the sleeve mounting tool 1B includes the sleeve cover gripping tool 9, when the exposed core wire WC1 of the first electric wire and the exposed core wire WC2 of the second electric wire are inserted into the sleeve SV, the movement of the sleeve cover SC is suppressed, and the sleeve The cover SC does not get in the way of work. Further, when the sleeve SV into which the exposed core WC1 and the exposed core WC2 are inserted is compressed by the compression tool, the movement of the sleeve cover SC is suppressed, and the sleeve cover SC does not interfere with the work. After the compression of the sleeve SV, the sleeve cover SC is moved to a position covering the sleeve SV, and the connection portion between the sleeve SV and the exposed cores (WC1, WC2) is protected by the sleeve cover SC.

  In the example shown in FIG. 2, the sleeve cover gripping tool 9 includes a first sleeve cover gripping tool 9a for gripping the first sleeve cover SC1 (see FIG. 13 etc.) and a second sleeve cover SC2 (see FIG. 15 etc.).

  When the sleeve cover gripping tool 9 includes a first sleeve cover gripping tool 9a and a second sleeve cover gripping tool 9b, a sleeve of a split type divided into a first sleeve cover SC1 and a second sleeve cover SC2 as a sleeve cover. A cover can be used. When the split sleeve cover is used, the length of each sleeve cover (first sleeve cover SC1, second sleeve cover SC2) is shortened. Therefore, even when the electric wire has some curvature, the operation of moving the sleeve cover along the electric wire (the first electric wire W1 or the second electric wire W2) can be easily performed. Note that after the first sleeve cover SC1 and the second sleeve cover SC2 are moved to a position covering the sleeve SV, the first sleeve cover SC1 and the second sleeve cover SC2 are connected to each other.

  An example of the structure of the sleeve cover gripping tool 9 will be described in more detail with reference to FIG.

  In the example illustrated in FIG. 7, the sleeve cover gripping tool 9 includes a mounting portion 93 attached to a slide bar (for example, the second slide bar 5) or an electric wire gripping tool (for example, the second electric wire gripping tool 7 b), and a sleeve cover. And a support portion 95 that supports the SC.

  The support portion 95 is provided with a sleeve cover gripper operating portion 952 that changes the state of the support portion 95 between a closed state and an open state. When the support portion 95 is in the closed state, the support portion 95 grips the sleeve cover SC. On the other hand, when the support portion 95 is in the open state, the sleeve cover SC can be inserted into the support portion 95 or the sleeve cover SC can be removed from the support portion 95. In the example illustrated in FIG. 7, the sleeve cover gripper operation unit 952 is an eye bolt or an eye nut having a through hole that can receive the tip of a remote control tool.

  In the example illustrated in FIG. 7, the support portion 95 that supports the sleeve cover SC includes a first divided body 958a and a second divided body 958b. The interval between the first divided body 958a and the second divided body 958b can be adjusted by operating the sleeve cover gripper operating portion 952. In the example illustrated in FIG. 7, the first divided body 958a and the second divided body 958b can approach and be separated along a direction (third direction) perpendicular to the first direction. The state in which the distance between the first divided body 958a and the second divided body 958b is reduced corresponds to the closed state in which the sleeve cover SC is gripped, and the first divided body 958a and the second divided body 958b The state in which the interval between the two is enlarged corresponds to the open state in which the grip state of the sleeve cover SC is released.

  The sleeve cover gripping tool 9 shown in FIG. 7 can be employed as the second sleeve cover gripping tool 9b shown in FIG. Further, the mirror body of the sleeve cover gripping tool 9 shown in FIG. 7 can be adopted as the first sleeve cover gripping tool 9a shown in FIG.

  The sleeve mounting tool 1B in the second embodiment has the same effects as the sleeve mounting tool 1A in the first embodiment. In addition, when the sleeve mounting tool 1B in the second embodiment includes at least one electric wire support 8, the end portion of the first electric wire W1 and the end portion of the second electric wire W2 can be distributed. . In this case, unintentional contact (short circuit) between the end of the first electric wire W1 and the end of the second electric wire W2 is suppressed. Further, when the sleeve mounting tool 1B in the second embodiment includes at least one sleeve cover gripping tool 9, the sleeve cover SC is prevented from moving. For this reason, the sleeve cover SC does not get in the way during the operation of inserting the exposed core wire into the sleeve SV or the operation of compressing the sleeve SV. In addition, the structure of the electric wire support 8 and / or the sleeve cover holding tool 9 in 2nd Embodiment may be employ | adopted in 1st Embodiment.

(Sleeve mounting method)
With reference to FIGS. 8 to 17, an example of a sleeve mounting method in the second embodiment will be described. FIG. 8 is a flowchart illustrating an example of a sleeve mounting method according to the second embodiment. Each of FIG. 9 to FIG. 17 is a diagram illustrating one process of the sleeve mounting method.

  In the first step ST101, the sleeve mounting tool 1B is attached to the electric wire W. The attachment is performed by attaching the first electric wire gripping tool 7a and the second electric wire gripping tool 7b to the electric wire W. In the example shown in FIG. 9, the sleeve mounting tool 1 </ b> B is attached to the electric wire W so as to face a portion (exposed portion A) where the coating layer of the electric wire W is peeled off and the core wire WC is exposed. Yes. Alternatively, after the sleeve mounting tool 1B is attached to the electric wire W, the coating layer of the electric wire W may be peeled off to form the exposed portion A.

  In the first step ST101, the electric wire W is preferably supported by the electric wire support 8 (specifically, the first electric wire support 8a and the second electric wire support 8b). The step of supporting the electric wire W by the electric wire support 8 includes, for example, moving the open / close members (82a, 82b) to the open position, moving the electric wires W into the frame members (81a, 81b), and then opening / closing members (82a). , 82b) are moved to the closed position. Note that either the step of supporting the electric wire W by the electric wire support 8 and the step of attaching the first electric wire gripping tool 7a and the second electric wire gripping tool 7b to the electric wire W may be executed first.

  In 2nd step ST102, by reducing the space | interval of the 1st electric wire holding tool 7a and the 2nd electric wire holding tool 7b, between the 1st electric wire holding tool 7a of the electric wires W and the 2nd electric wire holding tool 7b. The part to be positioned is bent (see FIG. 10). In the second step ST102, the slide bar operation unit 6 (for example, the first slide bar operation unit 6a) is operated to pull the first slide bar 4 to the base 2 side, and the slide bar operation unit 6 (for example, the second slide). The operation is performed by operating the bar operating portion 6b) and pulling the second slide bar 5 to the base 2 side. It should be noted that either the first slide rod 4 retracting step or the second slide rod 5 retracting step may be executed first. Alternatively, the drawing process of the first slide bar 4 and the drawing process of the second slide bar 5 may be alternately and repeatedly executed.

  In 3rd step ST103, the electric wire W is cut | disconnected by the cutting tool between the 1st electric wire holding tool 7a and the 2nd electric wire holding tool 7b. By the cutting, the electric wire W is separated into the first electric wire W1 and the second electric wire W2. In addition, it is preferable that a cutting | disconnection position is a part (exposed part A) where the core wire WC is exposed among the electric wires W. In this case, the end of the first electric wire W1 becomes the exposed core WC1 and the end of the second electric wire W2 becomes the exposed core WC2 by cutting. Instead of peeling off the coating layer of the electric wire before cutting the electric wire, the coating layer on the end portion of the first electric wire W1 and the end portion of the second electric wire W2 is peeled off after the cutting of the electric wire. Also good. In this case, it is not necessary to peel off the coating layer of the electric wire before the first step ST101.

  The cutting tool used in 3rd step ST103 is the cutting tool attached to the front-end | tip of a remote control tool, for example. FIG. 11 shows a state after the third step ST103 is executed.

  As shown in FIG. 12, in the fourth step ST104, the end of the first electric wire W1 and the end of the second electric wire W2 are distributed (for example, distributed up and down). In the fourth step ST104, for example, the end of the second electric wire W2 is moved from the second electric wire support 8b toward the third electric wire support 8c, and the end of the second electric wire W2 is moved to the third electric wire support 8c. It is executed by making it support by. Alternatively, the fourth step ST <b> 104 may be executed by rotating the second wire support 8 b that supports the end of the second wire W <b> 2 around the longitudinal axis of the base 2.

  In the fourth step ST104, in addition, in order to increase the distance between the end of the first electric wire W1 and the end of the second electric wire W2, the first slide bar 4 and / or the second slide bar 5 are , It may be moved in a direction protruding from the base 2. The movement is performed by operating the slide bar operation unit 6 (specifically, the first slide bar operation unit 6a and / or the second slide bar operation unit 6b).

  After execution of the fourth step ST104, an insulating cap IC (see FIG. 13) may be attached to one of the end portion of the first electric wire W1 and the end portion of the second electric wire W2. Alternatively, an insulating cap may be attached to both the end of the first electric wire W1 and the end of the second electric wire W2.

  During the execution of the first step ST101 to the fourth step ST104, the sleeve support 21 and the core support 26 are preferably in an open state. Similarly, during the execution of the first step ST101 to the fourth step ST104, the sleeve cover gripping tool 9 is preferably in an open state.

  As shown in FIG. 13, in the fifth step ST105, the first sleeve cover SC1 is pushed so that the first electric wire W1 passes through the inside of the first sleeve cover SC1, and then the first sleeve cover SC1 is the first sleeve cover SC1. It is gripped by the sleeve cover gripping tool 9a. The fifth step ST105 is executed using, for example, a remote control tool such as an insulating Yatsuko.

  In addition, when the insulating cap is attached to the end of the first electric wire W1, the insulating cap is removed from the end of the first electric wire W1 before the execution of the fifth step ST105. Further, as indicated by an arrow B, the first slide bar 4 may be moved in a direction protruding from the base 2 before the execution of the fifth step ST105.

  As shown in FIG. 13, in the sixth step ST <b> 106, the sleeve SV is supported by the sleeve support 21. In the sixth step ST106, first, the sleeve SV is placed on the sleeve support 21 by using a remote control tool such as an insulating tool. Thereafter, the sleeve support tool operating unit 212 is operated using the remote control tool, and the state of the sleeve support tool 21 is changed from the open state to the closed state. As a result, the sleeve SV is positioned and supported by the sleeve support 21. When the sleeve support 21 includes the first sleeve support 21a and the second sleeve support 21b, the sleeve SV is positioned and supported by the first sleeve support 21a and the second sleeve support 21b.

  As shown in FIG. 13, in the seventh step ST107, the exposed core wire WC1 of the first electric wire W1 is supported by the first core wire support 26a. In the seventh step ST107, first, the exposed core WC1 is moved into the first core support 26a using a remote control tool. Thereafter, the first core support unit 262a is operated using the remote control tool, and the state of the first core support 26a is changed from the open state to the closed state. As a result, the exposed core WC1 is restrained by the first core support 26a. By this restriction, centering between the sleeve SV and the exposed core WC1 is performed, and the bending wrinkle of the first electric wire W1 is corrected. As a result, the subsequent process (the process of inserting the exposed core WC1 into the sleeve SV) is executed smoothly.

  The seventh step ST107 may be executed before the sixth step ST106.

  As shown in FIG. 14, in the eighth step ST108, the exposed core wire WC1 of the first electric wire W1 is inserted into the sleeve SV. The eighth step ST108 is executed by operating the slide bar operating unit 6 (for example, the first slide bar operating unit 6a) and pulling the first slide bar 4 toward the base 2 side. By the execution of the eighth step ST108, the downward bending of the first electric wire W1 and the second electric wire W2 is reduced. Further, the execution of the eighth step ST108 causes the first sleeve cover SC1 to approach the first core wire support 26a.

  The first sleeve cover SC1 gripped by the first sleeve cover gripping tool 9a also functions as a restraining tool that maintains the first electric wire W1 in a linear shape. Therefore, when the sleeve mounting tool 1B includes the first sleeve cover gripping tool 9a, the process of inserting the exposed core WC1 into the sleeve SV is performed more smoothly.

  As shown in FIG. 15, in the ninth step ST109, the slide bar operation unit 6 (for example, the second slide bar operation unit 6 b) is operated, and the second slide bar 5 is moved in a direction protruding from the base 2. The By executing the ninth step ST109, the exposed core WC2 of the second electric wire W2 is retracted to the second direction side of the sleeve SV. In addition, the downward bending of the 1st electric wire W1 and the 2nd electric wire W2 increases by execution of 9th step ST109.

  If an insulating cap is attached to the end of the second electric wire W2, the insulating cap is removed from the end of the second electric wire W2 before the execution of the ninth step ST109.

  In the tenth step ST110, the second sleeve cover SC2 is pushed so that the second electric wire W2 passes through the inside of the second sleeve cover SC2, and then the second sleeve cover SC2 is gripped by the second sleeve cover gripping tool 9b. The The tenth step ST110 is executed using, for example, a remote control tool such as an insulating Yatco. In addition, 10th step ST110 is performed after moving the edge part of the 2nd electric wire W2 above the 2nd slide rod 5. FIG. The movement of the end of the second electric wire W2 includes, for example, transferring the end of the second electric wire W2 from the third electric wire support 8c into the second electric wire support 8b.

  In the eleventh step ST111, the exposed core WC2 of the second electric wire W2 is supported by the second core support 26b. In the eleventh step ST111, first, the exposed core WC2 is moved into the second core support 26b using a remote control tool. Thereafter, the second core wire support tool operating unit 262b is operated using the remote control tool, and the state of the second core wire support tool 26b is changed from the open state to the closed state. As a result, the exposed core WC2 is restrained by the second core support 26b. By this restriction, centering between the sleeve SV and the exposed core WC2 is performed, and the bending wrinkles of the second electric wire W2 are corrected.

  As shown in FIG. 16, in the twelfth step ST112, the exposed core WC2 of the second electric wire W2 is inserted into the sleeve SV. The twelfth step ST112 is executed by operating the slide bar operation unit 6 (for example, the second slide bar operation unit 6b) and pulling the second slide bar 5 toward the base 2 side. By performing the twelfth step ST112, downward bending of the first electric wire W1 and the second electric wire W2 is reduced. Further, the execution of the twelfth step ST112 causes the second sleeve cover SC2 to approach the second core wire support 26b.

  The second sleeve cover SC2 gripped by the second sleeve cover gripping tool 9b also functions as a restraining tool that maintains the second electric wire W2 in a linear shape. Therefore, when the sleeve mounting tool 1B includes the second sleeve cover gripping tool 9b, the process of inserting the exposed core WC2 into the sleeve SV is performed more smoothly.

  After execution of the twelfth step ST112, the sleeve support (21a, 21b) restrains the sleeve SV, the core wire support (26a, 26b) restrains the exposed core, and the sleeve cover gripping tool (9a, 9b). The constraint on the sleeve cover may be released or reduced. Release or reduction of these restraints is executed by operating the sleeve support tool operating unit 212, the core wire support tool operating unit 262, and the sleeve cover gripping tool operating unit 952 with a remote control tool. When the first slide bar 4 and / or the second slide bar 5 are pulled toward the base 2 in a state where these restraints are released or reduced, the exposed core wire WC1 and the exposed core wire WC2 are positioned deeper in the sleeve SV. Until inserted. And the 1st electric wire W1 and the 2nd electric wire W2 which were separated can be connected by compressing sleeve SV using a sleeve compression apparatus.

  In the thirteenth step ST113, the sleeve mounting tool 1B is removed from the first electric wire W1 and the second electric wire W2.

  In the 14th step ST114, the first sleeve cover SC1 and the second sleeve cover SC2 are moved to a position covering the sleeve SV, and the first sleeve cover SC1 and the second sleeve cover SC2 are connected.

  The present invention is not limited to the above-described embodiments, and it is apparent that the embodiments can be appropriately modified or changed within the scope of the technical idea of the present invention. In addition, any component used in each embodiment can be combined with other embodiments, and any component in each embodiment can be omitted.

  For example, in the example described in FIG. 1 or FIG. 2, the slide bar operating unit 6 includes a first slide bar operating unit 6 a that slides the first slide bar 4 and a second slide that slides the second slide bar 5. An example including the bar operation unit 6b has been described. Alternatively, as shown in FIG. 18, one slide bar operation unit 6 c may be capable of independently operating each of the first slide bar 4 and the second slide bar 5.

  In the example illustrated in FIG. 18, the slide bar operation unit 6 c is selectively applied to the first load transmission mechanism 61 that drives the first slide bar 4 or the second load transmission mechanism 62 that drives the second slide bar 5. Can be linked to. More specifically, the slide bar operation unit 6 c includes an operation unit side engagement unit 63, and the first load transmission mechanism 61 includes a first engagement unit 61 a that can be engaged with the operation unit side engagement unit 63. The second load transmission mechanism 62 includes a second engagement portion 62 a that can be engaged with the operation portion side engagement portion 63. And the operation part side engaging part 63 selectively engages with the 1st engaging part 61a or the 2nd engaging part 62a. In this way, the operating force acting on the slide bar operation part 6c can be selectively transmitted to the first slide bar 4 or the second slide bar 5 via the first engagement part 61a or the second engagement part 62a. it can.

  In the example illustrated in FIG. 18, the slide bar operation unit 6 c is attached to the base 2 so as to be relatively movable. An urging member 64 is interposed between the slide bar operating portion 6c and the base 2, and the urging member 64 can be used to connect the slide bar operating portion 6c to the first engaging portion 61a or the second engaging portion. Energize in the direction toward 62a. In the example illustrated in FIG. 18, the magnet 65 that is attracted to the first engagement portion 61 a (or the second engagement portion 62 a) is disposed in the operation portion side engagement portion 63. Alternatively or additionally, a magnet that attracts the operation portion side engaging portion 63 may be disposed in each of the first engaging portion 61a and the second engaging portion 62a.

  In the example illustrated in FIG. 18, the first load transmission mechanism 61 rotates together with the first bevel gear 61 b that rotates together with the first engagement portion 61 a and the first screw rod 61 c that engages with the first slide rod 4. Second bevel gear 61e. For this reason, when the slide bar operation portion 6c is operated so as to rotate around the first axis AT1, the first engagement portion 61a engaged with the operation portion side engagement portion 63 is first together with the first bevel gear 61b. Rotate around axis AT1. In the example shown in FIG. 18, the first bevel gear 61b and the second bevel gear 61e are meshed with each other. Therefore, when the first bevel gear 61b rotates around the first axis AT1, the second bevel gear 61e that meshes with the first bevel gear 61b, together with the first screw rod 61c, is perpendicular to the first axis AT1. Rotate around. The screw portion 61d of the first screw rod 61c is screwed with the first slide rod 4. For this reason, when the first screw rod 61c rotates around the second axis AT2, the first slide rod 4 slides in a direction along the second axis AT2.

  Similarly, in the example illustrated in FIG. 18, the second load transmission mechanism 62 includes a third bevel gear 62 b that rotates together with the second engagement portion 62 a and a second screw rod 62 c that is screwed into the second slide rod 5. And a fourth bevel gear 62e that rotates together. For this reason, when the slide bar operation part 6c is operated so as to rotate around the third axis AT3, the second engagement part 62a engaged with the operation part side engagement part 63 becomes the third bevel gear 62b and the third bevel gear 62b. Rotate around axis AT3. In the example shown in FIG. 18, the third bevel gear 62b and the fourth bevel gear 62e are meshed with each other. Therefore, when the third bevel gear 62b rotates about the third axis AT3, the fourth bevel gear 62e meshing with the third bevel gear 62b is moved together with the second screw rod 62c to the fourth axis AT4 perpendicular to the third axis AT3. Rotate around. The screw portion 62d of the second screw rod 62c is screwed with the second slide rod 5. For this reason, when the second screw rod 62c rotates around the fourth axis AT4, the second slide rod 5 slides in a direction along the fourth axis AT4. The fourth axis AT4 and the second axis AT2 are axes arranged on a straight line.

  In the example illustrated in FIG. 18, it is assumed that the engagement target of the operation unit side engagement unit 63 of the slide bar operation unit 6 c is switched from the first engagement unit 61 a to the second engagement unit 62 a. In this case, first, using a remote control tool, the slide bar operating portion 6c is moved away from the first engaging portion 61a against the urging force by the urging member 64 and / or the attracting force by the magnet 65. Move. Next, using the remote control tool, the slide bar operation portion 6c is slid from a position facing the first engagement portion 61a to a position facing the second engagement portion 62a. The base portion 2 is preferably provided with a guide portion such as a long hole for guiding the slide movement of the slide bar operation portion 6c. Subsequently, the slide bar operation portion 6 c is engaged with the second engagement portion 62 a by the urging force by the urging member 64 and / or the attraction force by the magnet 65.

  The operation of switching the engagement target of the operation portion side engagement portion 63 of the slide bar operation portion 6c from the second engagement portion 62a to the first engagement portion 61a is the operation portion side engagement portion 63 of the slide bar operation portion 6c. Since this is the same as the operation of switching the engagement target from the first engagement portion 61a to the second engagement portion 62a, repeated description will be omitted.

  FIG. 19 shows a modification of the attachment portion 23 that attaches at least one of the sleeve support 21 and the core support 26 to the rod-shaped portion 20 of the base 2. In the example described in FIG. 19, the attachment portion 23 is detachable from the rod-like portion 20 of the base portion 2.

  In the example shown in FIG. 19, the attachment portion 23 is movable relative to the attachment portion base member 23a and the attachment portion base member 23a to which at least one of the sleeve support 21 and the core wire support 26 is attached. Grip member 23b. When the grip member 23b is in a grip position with respect to the attachment portion base member 23a, the attachment portion 23 is fixed to the rod-shaped portion 20 by the grip member 23b and the attachment portion base member 23a. On the other hand, when the grip member 23b is in the grip open position with respect to the attachment portion base member 23a, the attachment portion 23 can be removed from the rod-shaped portion 20 (or the attachment portion 23 can be attached to the rod-shaped portion 20). is there.

  In the example shown in FIG. 19, the grip member 23b is swingably attached to the attachment portion base member 23a, and the grip member 23b swings around the first swing axis AS1 with respect to the attachment portion base member 23a. It is free to move. Each of the attachment portion base member 23a and the grip member 23b has an inner surface (more specifically, an arc-shaped surface) complementary to the outer surface shape of the rod-shaped portion 20. An elastic body 24a may be disposed on the inner surface of the attachment base member 23a to prevent slippage with respect to the rod-shaped portion 20. Similarly, the elastic body 24b for suppressing the slip with respect to the rod-shaped part 20 may be arrange | positioned at the inner surface of the grip member 23b.

  In the example shown in FIG. 19, a magnet 235 for holding the grip member 23b in the grip position is disposed on the grip member 23b. The magnet 235 is attracted by the attachment base member 23a and holds the grip member 23b in the grip position. Alternatively or additionally, a magnet for holding the grip member 23b in the grip position may be disposed on the attachment base member 23a.

  In the example illustrated in FIG. 19, the attachment portion 23 includes a lock member 25 that prevents the grip member 23 b from moving from the grip position toward the grip release position. For example, the lock member 25 is swingably attached to the attachment base member 23a. In the example shown in FIG. 19, the lock member 25 is swingable about the second swing axis AS2 with respect to the attachment base member 23a.

  When attaching the attachment portion 23 to the rod-shaped portion 20, first, the attachment portion base member 23 a is disposed around the rod-shaped portion 20. Next, the grip member 23b is moved from the grip release position toward the grip position. Thus, the attachment portion 23 is attached to the rod-like portion 20. Subsequently, by moving the lock member 25 from the unlocked position to the locked position, the grip member 23b is locked so as not to move from the grip position.

  When removing the attachment portion 23 from the rod-shaped portion 20, an operation opposite to the operation of attaching the attachment portion 23 to the rod-shaped portion 20 may be performed.

  In the example illustrated in FIG. 19, the attachment portion 23 includes an attachment portion base member 23 a and a grip member 23 b. For this reason, the attachment part 23 can be attached to the rod-like part 20 of the base 2 by a simple operation, and the attachment part 23 can be detached from the rod-like part 20 of the base 2 by a simple operation. Furthermore, being able to attach the attachment part 23 to the rod-like part 20 with a simple operation means that the position of the attachment part 23 can be changed along the longitudinal direction of the rod-like part 20 with a simple operation. In this case, the attachment position of the attachment portion 23 with respect to the rod-like portion 20 can be easily adjusted according to the length of the sleeve SV to be used.

  FIG. 20 shows a modification of the opening / closing operation mechanism M that opens and closes at least one of the sleeve support 21 and the core support 26. In the example shown in FIG. 4 or FIG. 5, the sleeve support 21 or the core support 26 is opened and closed by rotating an operation portion (212; 262) such as an eyebolt or an eyenut. On the other hand, in the example shown in FIG. 20, the sleeve support 21 or the core support 26 is opened and closed by a swing type operation lever (212a; 262a). The operation lever (212a; 262a) is, for example, a toggle lever.

  With reference to FIG. 20, an example of a mechanism in which the sleeve support 21 or the core support 26 is opened and closed by a swing type operation lever (212a; 262a) will be described.

  In the example shown in FIG. 20, when the operation lever (212a; 262a) is in the first position (for example, the upper position), the support (21; 26) is in the open state. In the example shown in FIG. 20, the open state of the support tool (21; 26) means a state in which the first divided body (218a; 268a) and the second divided body (218b; 268b) are spaced apart. In the example shown in FIG. 20, when the operation lever (212a; 262a) is in the second position (for example, the lower position), the support (21; 26) is in the closed state. In the example described in FIG. 20, the closed state of the support (21; 26) means a state in which the first divided body (218a; 268a) and the second divided body (218b; 268b) are arranged close to each other.

  In the example shown in FIG. 20, when the operation lever (212a; 262a) is moved from the first position (upper position) to the second position (lower position), the first pressing body 27a is changed to the first divided body (218a; 268a) is pressed in the direction toward the second divided body, and the second pressed body 27b presses the second divided body (218b; 268b) in the direction toward the first divided body. Thus, the support (21; 26) is closed.

  In the example illustrated in FIG. 20, the urging member 28 is disposed between the first divided body (218a; 268a) and the second divided body (218b; 268b). The urging member 28 has a first divided body (218a; 268a) and a second divided body (218b; 268b) in a direction in which the first divided body (218a; 268a) and the second divided body (218b; 268b) are separated from each other. ). Therefore, when the operation lever (212a; 262a) is moved from the second position (lower position) to the first position (upper position), the biasing member 28 causes the first divided body (218a; 268a) to move to the second position. The urging member 28 is pressed in a direction away from the divided body, and the second divided body (218b; 268b) is pressed in a direction away from the first divided body. Thus, the support (21; 26) is opened.

  In the example shown in FIG. 20, the first shaft 29a to which the first pressing body 27a is fixed is pivotally attached to the first pin 29c attached to the operation lever (212a; 262a). Further, the second pressing body 27b is slidable along the longitudinal direction of the first shaft 29a, and the second pressing body 27b is attached to the operation lever (212a; 262a) via the connecting member CN. ing. More specifically, the connecting member CN is pivotally attached to the second pressing body 27b via the second pin 29d, and is connected to the operation lever (212a; 262a) via the third pin 29e. It is pivotally mounted.

  In the example illustrated in FIG. 20, the operation lever (212a; 262a) is moved from the first position (upper position) to the second position (lower position), whereby the operation lever (212a; 262a) is moved to the third pin 29e. When rotating around the first pin 29c, the first pin 29c rotates around the third pin 29e. As a result, the first shaft 29a and the first pressing body 27a connected to the first pin 29c move in a direction approaching the second pressing body 27b. Thus, the support (21; 26) is closed.

  In the example shown in FIG. 20, a positioning stopper (more specifically, a centering pin CP) is provided on the support (21; 26). For this reason, when the support tool (21; 26) is in the closed state, the support tool (21; 26) is positioned at a position defined by the positioning stopper. In the example illustrated in FIG. 20, the position defined by the positioning stopper corresponds to a position immediately above the central axis of the rod-shaped portion 20.

  More specifically, the first divided body (218a; 268a) includes an engagement portion EN1 that can be engaged with the positioning stopper. For this reason, the first divided body (218a; 268a) cannot move to the second divided body side beyond the positioning stopper. The second divided body (218b; 268b) includes an engagement portion EN2 that can be engaged with the positioning stopper. For this reason, the second divided body (218b; 268b) cannot move to the first divided body side beyond the positioning stopper. Thus, the first divided body (218a; 268a) and the second divided body (218b; 268b) come into contact with each other at the position where the positioning stopper is disposed.

  As the opening / closing operation mechanism M, a toggle clamp (model number: MC02-S2) manufactured by MISUMI Corporation may be used.

  In the example shown in FIG. 20, the support (21; 26) is opened and closed by the swing type operation lever (212a; 262a). Therefore, the support (21; 26) can be easily opened and closed using the remote control tool.

  By using the sleeve mounting tool and the sleeve mounting method of the present invention, the exposed core wire of the first wire and the exposed core wire of the second wire can be easily operated while suppressing the overall slack of the first wire and the second wire. A sleeve SV can be attached to the. Therefore, it is useful for manufacturers of sleeve mounting tools and contractors who perform sleeve mounting operations.
