(First Embodiment)
The sleeve mounting tool 1A according to the first embodiment will be described with reference to FIG. 1 (a) to 1 (d) are schematic front views of the sleeve mounting tool 1A according to the first embodiment.

The sleeve mounting tool 1A in the first embodiment includes a base 2, a first slide rod 4, a second slide rod 5, a slide rod operation unit 6, a first electric wire gripping tool 7a, and a second electric wire gripping tool. 7b and the like.

The base 2 includes a sleeve support 21 for supporting the sleeve SV and a core support 26 for supporting the exposed core wire WC.

In the example shown in FIG. 1, a first sleeve support 21a for supporting one end of the sleeve SV is provided at the end of the base 2 on the first direction side, and the end of the base 2 on the second direction side is provided. , A second sleeve support 21b that supports the other end of the sleeve SV is provided. In the example shown in FIG. 1, the base 2 includes two sleeve supports (21a, 21b), but the base 2 may include one or three or more sleeve supports. .. Further, the arrangement of each sleeve support on the base 2 is not limited to the example shown in FIG. 1, and is arbitrary.

In the example shown in FIG. 1, a first core wire supporter 26a for supporting the exposed core wire WC1 of the first electric wire W1 is provided at the end portion of the base portion 2 on the first direction side, and the second core wire supporter 26a is provided. At the end on the directional side, a second core wire supporter 26b for supporting the exposed core wire WC2 of the second electric wire W2 is provided. In the example shown in FIG. 1, the base 2 includes two core wire supports (26a, 26b), but the number of core wire supports included in the base 2 may be three or more. In the example shown in FIG. 1, the first core wire support 26a is arranged on the first direction side of the sleeve support 21 (more specifically, the first sleeve support 21a), and the second core wire support is provided. 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 arranged between the first core wire support 26a and the second core wire support 26b.

In the example shown in FIG. 1, the sleeve support 21 and the core support 26 are separate bodies, 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 wire support 26 may be shared.

When the alignment state between the central axis of the exposed core wire WC and the central axis of the sleeve SV is maintained by using a remote control tool, or when the sleeve support 21 also has the function of the core wire support, etc. The core wire support 26 may be omitted.

The first slide rod 4 is a member that is arranged on one side of the base portion 2 (in the example shown in FIG. 1, the first direction side) and is slidable with respect to the base portion 2. By operating the slide rod operating portion 6, the first slide rod 4 changes the amount of protrusion of the base portion 2 from the first direction side end portion 20a. In the example shown in FIG. 1, when the slide rod operation unit 6 (more specifically, the first slide rod operation unit 6a) is operated in the first operation direction R1, the first slide rod 4 is pulled toward the base 2 side. .. As a result, the amount of protrusion of the first slide rod 4 from the first direction side end portion 20a is reduced. On the other hand, when the slide rod operation unit 6 (more specifically, the first slide rod operation unit 6a) is operated in the second operation direction, the first slide rod 4 moves in the direction of protruding from the base 2 side. As a result, the amount of protrusion of the first slide rod 4 from the first direction side end portion 20a increases.

The second slide rod 5 is a member that is arranged on the other side of the base portion 2 (in the example shown in FIG. 1, the second direction side) and is slidable with respect to the base portion 2. By operating the slide rod operating portion 6, the second slide rod 5 changes the amount of protrusion of the base portion 2 from the second direction side end portion 20b. In the example shown in FIG. 1, when the slide rod operation unit 6 (more specifically, the second slide rod operation unit 6b) is operated in the first operation direction R3, the second slide rod 5 is pulled toward the base 2 side. .. As a result, the amount of protrusion of the second slide rod 5 from the second direction side end portion 20b is reduced. On the other hand, when the slide rod operation unit 6 (more specifically, the second slide rod operation unit 6b) is operated in the second operation direction R4, the second slide rod 5 moves in the direction of protruding from the base 2 side. As a result, the amount of protrusion of the second slide rod 5 from the second direction side end portion 20b increases.

The slide rod operation unit 6 is an operation unit for sliding and moving the first slide rod 4 and the second slide rod 5. In the example described in FIG. 1, the slide rod operation unit 6 includes a first slide rod operation unit 6a that slides and moves the first slide rod 4, and a second slide rod operation unit 6b that slides and moves the second slide rod 5. To prepare for. Then, the slide movement of the first slide rod 4 and the slide movement of the second slide rod 5 are independently operated. More specifically, when the first slide rod operation unit 6a is operated, the first slide rod 4 moves relative to the base 2, but the second slide rod 5 does not move relative to the base 2. Further, when the second slide rod operation unit 6b is operated, the second slide rod 5 moves relative to the base 2, but the first slide rod 4 does not move relative to the base 2.

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

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

The second electric wire gripping tool 7b grips the second electric wire W2 (more specifically, the portion WP2 of the second electric wire W2 in which the core wire is not exposed). The second electric wire gripper 7b is connected to the end of the second slide rod 5. Therefore, when the second slide rod 5 slides and moves with respect to the base 2, the second electric wire gripping tool 7b moves relative to the base 2. In the example shown in FIG. 1, the sleeve mounting tool 1A includes a second wire gripping tool 7b. Alternatively, in the shipping state or the like, the sleeve mounting tool 1A may not be provided with the second wire gripping tool 7b, and the sleeve mounting tool 1A may be configured to be mounted on the existing second wire gripping tool.

In the sleeve mounting tool 1A of the first embodiment, the slide rod operating unit 6 can independently operate the slide movement of the first slide rod 4 and the slide movement of the second slide rod 5. Therefore, when inserting the exposed core wire WC1 of the first electric wire W1 into the sleeve SV, the first slide rod 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 wire WC2 of the second electric wire W2 into the sleeve SV, the second slide rod 5 may be moved by a distance shorter than the length of the sleeve SV (FIG. 1 (FIG. 1). c) and FIG. 1 (d)). Therefore, in the process of connecting the first electric wire W1 and the second electric wire W2 via the sleeve SV, the increase in the distance between the first electric wire gripping tool 7a and the second electric wire gripping tool 7b is compared with the conventional one. Can be suppressed. As a result, it is possible to suppress the slackening of the first electric wire W1 and the second electric wire W2 as a whole.

Further, the base portion 2 of the sleeve mounting tool 1A in the first embodiment may be divided or bendable at a substantially central portion. When it is possible to divide, for example, a concave portion may be provided on one of the divided bodies 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 screws or the like after engaging. Alternatively, the shape of the divided body is such that the divided bodies are not separated from each other when a force is applied in the first direction and the second direction, and one divided body is made into the first direction and the second divided body with respect to the other divided body. Both splits may be coupled and / or separable by moving in the vertical direction. Further, when it is possible to bend it, it may be joined by a hinge or the like so that the base portion 2 can be bent at a substantially central portion. Since the sleeve mounting tool 1A can be folded in half by being split or bendable at a substantially central portion of the base portion 2, the sleeve mounting tool 1A can be made compact during transportation and storage.

Further, the end of the exposed core wire WC tends to spread in the outer diameter direction, and conventionally, it has not been easy to insert the exposed core wire WC into the sleeve opening slightly larger than the inner diameter of the exposed core wire WC. On the other hand, in the first embodiment, when the sleeve mounting tool 1A includes the core wire support 26, in the step of inserting the exposed core wire WC into the sleeve SV, between the exposed core wire WC and the sleeve SV. Can be easily centered. Therefore, the work of inserting the exposed core wire WC into the sleeve opening becomes easy. More specifically, the slide rod (first slide rod 4 or second slide rod 5) is based on the sleeve SV supported by the sleeve support 21 and the exposed core wire WC supported by the core wire support 26. When pulled to the 2 side, the exposed core wire WC is automatically inserted into the sleeve SV. Therefore, the operator can easily insert the exposed core wire WC into the sleeve SV.

(Sleeve mounting method)
The 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 first slide rod 4 is pulled toward the base 2 side, and the first electric wire W1 gripped by the first electric wire gripper 7a is moved in the second direction, whereby the exposed center of the first electric wire W1 is exposed. The wire WC1 is inserted into the first end of the sleeve SV. FIG. 1B shows the state after the second step ST2 is executed. The second step ST2 is performed, for example, by operating the slide rod operation unit 6 (more specifically, the first slide rod operation unit 6a).

In the third step ST3, by moving the second slide rod 5 in the direction protruding from the base 2 side, the second electric wire W2 gripped by the second electric wire gripper 7b is moved in the second direction. FIG. 1 (c) shows the state after the third step ST3 is executed. The third step ST3 is performed, for example, by operating the slide rod operation unit 6 (more specifically, the second slide rod operation unit 6b).

If the end of the exposed core wire WC2 and the end of the sleeve SV on the second direction side do not face each other after the execution of the third step ST3, the exposed core wire WC2 is used by using a remote control tool. The end portion of the sleeve SV may be moved to a position facing the second-direction side end portion of the sleeve SV. More specifically, a remote control tool may be used to move the end of the exposed core wire WC2 so that the end portion is supported by the second core wire support tool 26b.

In the fourth step ST4, the second slide rod 5 is pulled toward the base 2 side, and the second electric wire W2 gripped by the second electric wire gripper 7b is moved in the first direction to expose the exposed center of the second electric wire W2. The wire WC2 is inserted into the second end of the 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 rod operation unit 6 (more specifically, the second slide rod operation unit 6b).

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

(Second embodiment)
The sleeve mounting tool 1B in the second embodiment will be described with reference to FIGS. 2 to 7. FIG. 2 is a schematic front view of the sleeve mounting tool 1B in the second embodiment. FIG. 3 is a schematic front view showing an example of the sleeve support 21 and the core wire 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 wire support 26. FIG. 6 is a schematic side view showing an example of the electric wire support 8. FIG. 7 is a schematic two-view view showing 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. 7.

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

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

(Base 2)
In the example shown in FIG. 2, the base 2 includes a rod-shaped portion 20 extending along the first direction, a sleeve support 21, a core wire support 26, and a slide rod operation portion 6.

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

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

In the example shown in FIG. 3, the sleeve support 21 includes a mounting portion 23 attached to the rod-shaped portion 20 and a support portion 210 for supporting the sleeve SV and the like. The mounting portion 23 is provided with a through hole 231 for receiving a part of the rod-shaped portion 20 (see FIG. 4). The sleeve support 21 may be adjustable in position with respect to the rod-shaped portion 20 along the first direction. 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 corresponding to the diameter of the sleeve SV actually used can be attached to the rod-shaped portion 20. Therefore, the versatility of the sleeve mounting tool 1B is improved.

The support portion 210 is provided with a sleeve support operation portion 212 that changes the state of the support portion between the closed state and the 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 move substantially 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 shown in FIG. 3, the sleeve support operating portion 212 is an eyebolt or eyenut having a through hole capable of accepting the tip of a remote control tool.

In the example shown in FIG. 3, the support portion 210 includes a first portion 214 for supporting the sleeve SV and a second portion 216 through which the exposed core wire WC is inserted. Further, in the example shown in FIG. 3, the inner surface of the second portion 216 is provided with a tapered surface 216a whose diameter is reduced toward the first portion 214. Since the second portion 216 is provided with the tapered surface 216a, the exposed core wire WC can be smoothly inserted into the second portion 216 even when the end of the exposed core wire WC is widened or bent. 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 facing the end surface of the sleeve SV and an outer peripheral surface support surface 214b facing the outer peripheral surface of the sleeve SV.

In the example described 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 wire. In the example shown in FIG. 3, the mounting portion 23 of the core wire support 26 and the mounting 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 mounting portion 23 can be mounted on the rod-shaped portion 20 while maintaining the positional relationship between the sleeve support 21 and the core wire support 26. As in the example shown in FIG. 1, the mounting portion of the core wire support 26 and the mounting portion of the sleeve support 21 may be separate bodies.

The support portion 260 is provided with a core wire support operation unit 262 that changes the state of the support portion between the closed state and the open state. When the support 260 is in the closed state, the support 260 constrains the exposed core WC and / or the covered wire, and the exposed core WC moves relative to the support 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 wire WC and / or the covered wire may be placed on the support portion 260, or the exposed core wire WC and / or the covered wire may be removed from the support portion 260. It is possible. In the example shown in FIG. 3, the core wire support operating unit 262 is an eye bolt or eye nut having a through hole capable of accepting 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 wire is inserted. Although not shown in FIG. 3, the inner surface of the core wire receiving portion 267 may have a tapered surface whose diameter decreases 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 shown 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. The presence of the gap G allows the operator to confirm whether or not the exposed core wire WC inserted from the core wire support tool 26 side has reached the sleeve support tool 21. In other words, the operator can confirm whether or not the work of inserting the exposed core wire WC into the sleeve SV is proceeding smoothly. The gap G may not be provided.

The sleeve support 21 will be further described with reference to FIG. In the example shown in FIG. 4, the support portion 210 that supports the sleeve SV includes the first divided body 218a and the second divided body 218b. Then, by operating the sleeve support operation unit 212, the distance between the first divided body 218a and the second divided body 218b can be adjusted. In the example shown in FIG. 4, the first divided body 218a and the second divided body 218b are close to each other and can be separated from each other along a direction perpendicular to the first direction (third direction). The state in which the distance between the first divided body 218a and the second divided body 218b becomes small corresponds to the closed state in which the sleeve SV is constrained, and the first divided body 218a and the second divided body 218b The state in which the interval between them is expanded corresponds to the open state in which the restraint of the sleeve SV is released.

As shown in FIG. 4, one of the first divided body 218a and the second divided body 218b is provided with a guide member 219 (for example, a guide plate) for guiding the insertion of the sleeve SV into the sleeve receiving portion 215. It may have been. Since one of the first divided body 218a and the second divided body 218b is provided with the guide member 219, the sleeve SV can be smoothly inserted into the sleeve receiving portion 215. In the example shown in FIG. 4, the guide member 219 includes a guide surface 219c perpendicular to the third direction.

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 the electric wire is cut (note that "supporting the end portion" includes "defining the position of the end portion". ).

The third electric wire support 8c is arranged on the side opposite to the second electric wire support 8b with respect to the base 2. In other words, when the second wire support 8b is located above the base 2, the third wire support 8c is configured to be located below the base 2. By moving the second electric wire W2 using a remote control tool, the position of the end portion 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. Imagine changing 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).

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

When the sleeve mounting tool 1B includes the sleeve cover gripping tool 9, the movement of the sleeve cover SC is suppressed 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, and the sleeve. The cover SC does not get in the way of work. Further, when the sleeve SV into which the exposed core wire WC1 and the exposed core wire 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 compression of the sleeve SV, the sleeve cover SC is moved to a position covering the sleeve SV, and the sleeve cover SC protects the connection portion between the sleeve SV and the exposed core wires (WC1, WC2).

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 and the like) and a second sleeve cover SC2 (FIG. 15 and the like).

Attached to.

When the sleeve cover grip 9 includes the first sleeve cover grip 9a and the second sleeve cover grip 9b, the sleeve cover is a split type sleeve divided into a first sleeve cover SC1 and a second sleeve cover SC2. A cover can be used. When the split type sleeve cover is used, the length of each sleeve cover (first sleeve cover SC1 and second sleeve cover SC2) is shortened. Therefore, even if the electric wire is slightly curved, the work of moving the sleeve cover along the electric wire (first electric wire W1 or the second electric wire W2) can be easily performed. After the first sleeve cover SC1 and the second sleeve cover SC2 are moved to positions that cover 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. 7.

A support portion 95 for supporting the SC is provided.

The support portion 95 is provided with a sleeve cover gripping tool operating portion 952 that changes the state of the support portion 95 between the closed state and the 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, and the sleeve cover SC can be removed from the support portion 95. In the example shown in FIG. 7, the sleeve cover gripping tool operation unit 952 is an eye bolt or eye nut having a through hole capable of receiving the tip of a remote control tool.

In the example shown in FIG. 7, the support portion 95 that supports the sleeve cover SC includes the first divided body 958a and the second divided body 958b.

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 separated. .. In this case, an unintended 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. Therefore, the sleeve cover SC does not get in the way during the work of inserting the exposed core wire into the sleeve SV or the work of compressing the sleeve SV. The configuration of the electric wire support 8 and / or the sleeve cover gripping tool 9 in the second embodiment may be adopted in the first embodiment.

(Sleeve mounting method)
An example of the sleeve mounting method in the second embodiment will be described with reference to FIGS. 8 to 17. FIG. 8 is a flowchart showing an example of the sleeve mounting method in the second embodiment. Each of FIGS. 9 to 17 is a diagram showing one step 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 1B is attached to the electric wire W so as to face the portion (exposed portion A) where the coating layer of the electric wire W is stripped off and the core wire WC is exposed. There is. Alternatively, after the sleeve mounting tool 1B is attached to the electric wire W, the covering 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).

This is executed by operating the rod operating unit 6b) and pulling the second slide rod 5 toward the base 2. Either the pull-in step of the first slide rod 4 or the pull-in step of the second slide rod 5 may be executed first. Alternatively, the pull-in step of the first slide rod 4 and the pull-in step of the second slide rod 5 may be alternately and repeatedly executed.

In the third step ST103, the electric wire W is cut by the cutting tool between the first electric wire gripping tool 7a and the second electric wire gripping tool 7b. By the cutting, the electric wire W is separated into the first electric wire W1 and the second electric wire W2. The cutting position is preferably a portion of the electric wire W where the core wire WC is exposed (exposed portion A). In this case, by cutting, the end of the first electric wire W1 becomes the exposed core wire WC1, and the end of the second electric wire W2 becomes the exposed core wire WC2. Instead of stripping the coating layer of the electric wire before cutting the electric wire, the coating layer of the end portion of the first electric wire W1 and the end portion of the second electric wire W2 is stripped off after the electric wire is cut. May be good. In this case, it is not necessary to strip the coating layer of the electric wire before the first step ST101.

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

As shown in FIG. 12, in the fourth step ST104, the end portion of the first electric wire W1 and the end portion of the second electric wire W2 are distributed (for example, they are distributed vertically). 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 carried out by being endorsed by. Alternatively, the fourth step ST104 may be performed by rotating the second wire supporter 8b, which supports the end of the second wire W2, around the longitudinal axis of the base 2.

In the fourth step ST104, the first slide rod 4 and / or the second slide rod 5 additionally increases the distance between the end portion of the first electric wire W1 and the end portion of the second electric wire W2. , May be moved in a direction protruding from the base 2. The movement is performed by operating the slide rod operation unit 6 (specifically, the first slide rod operation unit 6a and / or the second slide rod operation unit 6b).

After the execution of the fourth step ST104, the 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, insulating caps may be attached to both the end of the first electric wire W1 and the end of the second electric wire W2.

It is preferable that the sleeve support 21 and the core wire support 26 are in the open state during the execution of the first step ST101 to the fourth step ST104. Similarly, it is preferable that the sleeve cover gripping tool 9 is in the open state during the execution of the first step ST101 to the fourth step ST104 described above.

It is gripped by the sleeve cover gripper 9a. The fifth step ST105 is executed using, for example, a remote control tool such as an insulating yatco.

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 shown by the arrow B, the first slide rod 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 ST106, 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 yatko. After that, the sleeve support operation unit 212 is operated by using the remote control tool, and the state of the sleeve support 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.

After that, the first core wire support tool operating unit 262a is operated by using the remote control tool, and the state of the first core wire support tool 26a is changed from the open state to the closed state. As a result, the exposed core wire WC1 is constrained by the first core wire supporter 26a. By the restraint, the centering between the sleeve SV and the exposed core wire WC1 is performed, and the bending habit of the first electric wire W1 is corrected. As a result, the subsequent step (the step of inserting the exposed core wire WC1 into the sleeve SV) is smoothly executed.

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 rod operating unit 6 (for example, the first slide rod operating unit 6a) and pulling the first slide rod 4 toward the base 2. By executing the eighth step ST108, the downward bending of the first electric wire W1 and the second electric wire W2 is reduced. Further, by executing the eighth step ST108, the first sleeve cover SC1 approaches the first core wire support tool 26a.

The first sleeve cover SC1 gripped by the first sleeve cover grip 9a also functions as a restraint for maintaining 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 step of inserting the exposed core wire WC1 into the sleeve SV is performed more smoothly.

As shown in FIG. 15, in the ninth step ST109, the slide rod operating unit 6 (for example, the second slide rod operating unit 6b) is operated, and the second slide rod 5 is moved in a direction protruding from the base 2. Slide. By executing the ninth step ST109, the exposed core wire WC2 of the second electric wire W2 is retracted to the second direction side of the sleeve SV. By executing the ninth step ST109, the downward bending of the first electric wire W1 and the second electric wire W2 increases.

When the 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 gripper 9b.

The tenth step ST110 is executed after the end portion of the second electric wire W2 is moved above the second slide rod 5. The movement of the end portion of the second electric wire W2 includes, for example, transferring the end portion of the second electric wire W2 from the inside of the third electric wire support 8c to the inside of the second electric wire support 8b.

In the eleventh step ST111, the exposed core wire WC2 of the second electric wire W2 is supported by the second core wire supporter 26b. In the eleventh step ST111, first, the exposed core wire WC2 is moved into the second core wire support tool 26b by using a remote control tool. After that, the second core wire support operation unit 262b is operated by 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 wire WC2 is constrained by the second core wire supporter 26b. By the restraint, the centering between the sleeve SV and the exposed core wire WC2 is performed, and the bending habit of the second electric wire W2 is corrected.

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

The second sleeve cover SC2 gripped by the second sleeve cover grip 9b also functions as a restraint for maintaining 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 step of inserting the exposed core wire WC2 into the sleeve SV is performed more smoothly.

After the execution of the twelfth step ST112, the sleeve support (21a, 21b) restrains the sleeve SV, the core support (26a, 26b) restrains the exposed core, and the sleeve cover gripper (9a, 9b). Restraints on the sleeve cover may be released or reduced. The release or reduction of these restraints is performed by operating the sleeve support operation unit 212, the core wire support operation unit 262, and the sleeve cover grip operation unit 952 with a remote control tool. When the first slide rod 4 and / or the second slide rod 5 is pulled toward the base 2 with these restraints released or reduced, the exposed core wire WC1 and the exposed core wire WC2 are placed at a deeper position of the sleeve SV. Will be inserted. Then, by compressing the sleeve SV using the sleeve compression device, the separated first electric wire W1 and the second electric wire W2 can be connected.

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 positions covering the sleeve SV, and the first sleeve cover SC1 and the second sleeve cover SC2 are connected to each other.

It is clear that the present invention is not limited to each of the above embodiments, and each embodiment can be appropriately modified or modified within the scope of the technical idea of the present invention. Further, any component used in each embodiment can be combined with other embodiments, and any component can be omitted in each embodiment.

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

In the example shown in FIG. 18, the slide rod operating unit 6c is selectively selected for the first load transmission mechanism 61 for driving the first slide rod 4 or the second load transmission mechanism 62 for driving the second slide rod 5. Can be connected to. More specifically, the slide rod operating portion 6c includes an operating portion side engaging portion 63, and the first load transmission mechanism 61 has a first engaging portion 61a that can be engaged with the operating portion side engaging portion 63. The second load transmission mechanism 62 includes a second engaging portion 62a that can be engaged with the operating portion side engaging portion 63. Then, the operating portion side engaging portion 63 selectively engages with the first engaging portion 61a or the second engaging portion 62a. In this way, the operating force acting on the slide rod operating portion 6c can be selectively transmitted to the first slide rod 4 or the second slide rod 5 via the first engaging portion 61a or the second engaging portion 62a. can.

In the example shown in FIG. 18, the slide rod operating portion 6c is attached so as to be relatively movable with respect to the base portion 2. An urging member 64 is interposed between the slide rod operating portion 6c and the base portion 2, and the urging member 64 connects the slide rod operating portion 6c to the first engaging portion 61a or the second engaging portion. Elevate in the direction toward 62a. Further, in the example shown in FIG. 18, a magnet 65 attracted to the first engaging portion 61a (or the second engaging portion 62a) is arranged on the operating portion side engaging portion 63. Alternatively or additionally, a magnet for attracting the operating portion side engaging portion 63 may be arranged in each of the first engaging portion 61a and the second engaging portion 62a.

In the example described in FIG. 18, the first load transmission mechanism 61 rotates together with the first bevel gear 61b that rotates together with the first engaging portion 61a and the first screw rod 61c that is screwed into the first slide rod 4. A second bevel gear 61e is provided. Therefore, when the slide rod operating portion 6c is operated so as to rotate around the first axis AT1, the first engaging portion 61a engaged with the operating portion side engaging portion 63 is first together with the first bevel gear 61b. Rotate around the 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, has the second axis AT2 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. Therefore, when the first screw rod 61c rotates around the second axis AT2, the first slide rod 4 slides and moves in the direction along the second axis AT2.

Similarly, in the example shown in FIG. 18, the second load transmission mechanism 62 has a third bevel gear 62b that rotates together with the second engaging portion 62a and a second screw rod 62c that is screwed into the second slide rod 5. It is provided with a fourth bevel gear 62e that rotates together with the bevel gear 62e. Therefore, when the slide rod operating portion 6c is operated so as to rotate around the third axis AT3, the second engaging portion 62a engaged with the operating portion side engaging portion 63 is third together with the third bevel gear 62b. Rotate around the 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 around the third axis AT3, the fourth bevel gear 62e meshing with the third bevel gear 62b, together with the second screw rod 62c, is 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. Therefore, when the second screw rod 62c rotates around the fourth axis AT4, the second slide rod 5 slides and moves in the direction along the fourth axis AT4. The fourth axis AT4 and the second axis AT2 are axes arranged in a straight line.

In the example shown in FIG. 18, it is assumed that the engagement target of the operation portion side engaging portion 63 of the slide rod operating portion 6c is switched from the first engaging portion 61a to the second engaging portion 62a. In this case, first, using a remote control tool, the slide rod operating portion 6c is separated from the first engaging portion 61a against the urging force by the urging member 64 and / or the attractive force by the magnet 65. Move it. Next, using a remote control tool, the slide rod operating portion 6c is slid and moved from the position facing the first engaging portion 61a to the position facing the second engaging portion 62a. It is preferable that the base portion 2 is provided with a guide portion such as an elongated hole for guiding the slide movement of the slide rod operating portion 6c. Subsequently, the slide rod operating portion 6c engages with the second engaging portion 62a by the urging force of the urging member 64 and / or the attractive force of the magnet 65.

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

The grip member 23b is provided. When the grip member 23b is in the grip position with respect to the mounting portion base member 23a, the mounting portion 23 is fixed to the rod-shaped portion 20 by the grip member 23b and the mounting portion base member 23a. On the other hand, when the grip member 23b is in the grip open position with respect to the mounting portion base member 23a, the mounting portion 23 can be removed from the rod-shaped portion 20 (or the mounting portion 23 can be attached to the rod-shaped portion 20). be.

In the example described in FIG. 19, the grip member 23b is swingably attached to the mounting portion base member 23a, and the grip member 23b swings around the first swing shaft AS1 with respect to the mounting portion base member 23a. It is movable. Each of the mounting 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 for suppressing slippage with respect to the rod-shaped portion 20 may be arranged on the inner surface of the mounting portion base member 23a. Similarly, an elastic body 24b for suppressing slippage with respect to the rod-shaped portion 20 may be arranged on the inner surface of the grip member 23b.

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

In the example shown in FIG. 19, the mounting portion 23 includes a lock member 25 that prevents the grip member 23b from moving from the grip position to the grip open position. The lock member 25 is swingably attached to, for example, the attachment base member 23a. In the example shown in FIG. 19, the lock member 25 is swingable around the second swing shaft AS2 with respect to the mounting portion base member 23a.

When attaching the mounting portion 23 to the rod-shaped portion 20, first, the mounting portion base member 23a is arranged around the rod-shaped portion 20. Next, the grip member 23b is moved from the grip open position toward the grip position. In this way, the mounting portion 23 is mounted on the rod-shaped portion 20. Subsequently, by moving the lock member 25 from the lock release position to the lock position, the grip member 23b is locked so as not to move from the grip position.

When removing the mounting portion 23 from the rod-shaped portion 20, the operation opposite to the operation of attaching the mounting portion 23 to the rod-shaped portion 20 may be executed.

In the example shown in FIG. 19, the mounting portion 23 includes a mounting portion base member 23a and a grip member 23b. Therefore, the mounting portion 23 can be attached to the rod-shaped portion 20 of the base 2 with a simple operation, and the mounting portion 23 can be removed from the rod-shaped portion 20 of the base 2 with a simple operation. Further, the fact that the mounting portion 23 can be attached to the rod-shaped portion 20 with a simple operation means that the mounting portion 23 can be repositioned along the longitudinal direction of the rod-shaped portion 20 with a simple operation. In this case, the mounting position of the mounting portion 23 with respect to the rod-shaped portion 20 can be easily adjusted according to the length of the sleeve SV to be used.

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

In the example shown in FIG. 20, when the operating lever (212a; 262a) is in the first position (eg, 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 (21; 26) means a state in which the first divided body (218a; 268a) and the second divided body (218b; 268b) are separated from each other. In the example shown in FIG. 20, when the operating lever (212a; 262a) is in the second position (eg, lower position), the support (21; 26) is in the closed state. In the example shown 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 in close proximity to each other.

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

In the example shown in FIG. 20, the urging member 28 is arranged 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 operating lever (212a; 262a) moves from the second position (lower position) to the first position (upper position), the urging member 28 moves the first division body (218a; 268a) to the second position. Pressing in a direction away from the split body, the urging member 28 presses the second split body (218b; 268b) in a direction away from the first split body. In this way, 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 operating 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 operating 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 attached to the operating lever (212a; 262a) via the third pin 29e. It is mounted pivotally.

In the example shown in FIG. 20, the operating lever (212a; 262a) is moved from the first position (upper position) to the second position (lower position), so that the operating lever (212a; 262a) is moved to the third pin 29e. 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. In this way, the support (21; 26) is closed.

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

More specifically, the first divided body (218a; 268a) includes an engaging portion EN1 that can be engaged with the positioning stopper. Therefore, the first divided body (218a; 268a) cannot move beyond the positioning stopper to the second divided body side. Further, the second divided body (218b; 268b) includes an engaging portion EN2 that can be engaged with the positioning stopper. Therefore, the second divided body (218b; 268b) cannot move beyond the positioning stopper to the first divided body side. In this way, 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 arranged.

A toggle clamp (model number: MC02-S2) manufactured by Misumi Corporation may be used for the opening / closing operation mechanism M.

In the example shown in FIG. 20, the swing-type operating lever (212a; 262a) opens and closes the support (21; 26). Therefore, the support (21; 26) can be easily opened and closed by 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 electric wire and the exposed core wire of the second electric wire can be easily operated while suppressing the slackening of the entire first electric wire and the second electric wire. The sleeve SV can be attached to the. Therefore, it is useful for the manufacturer of the sleeve mounting tool and the manufacturer performing the sleeve mounting work.
