Description

Sleeve mounting tool, and sleeve mounting method

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

A method of separating electric wires is known. In the electric wire separation method, an overhead electric wire is separated into a first electric wire and a second electric wire. After the necessary work is performed on the grounding side of the overhead electric wire, the separated first electric wire and the second electric wire are connected via a sleeve.

As a related technique, Patent Document 1 describes a method for constructing a braided wire. In the temporary wire construction method described in Patent Document 1, the coated part of one insulated wire is gripped by one gripper, and the other coated wire in a state in which a cylindrical connection sleeve is attached to the core wire of the other coated wire. The covering portion is gripped by the other gripper. After that, the distance between one gripper and the other gripper is reduced by rotating the operation part of the expansion/contraction machine with a remote operation tool, and the core wire of one sheathed electric wire is connected from the opening of one end of the connection sleeve to the connection sleeve. inserted within

Moreover, in patent document 2, the daytime tool for electric wire separation work is described. The tool described in Patent Document 2 includes a telescopic operation body having an operating shaft and a pair of expansion and contraction rods comprising an inner and outer cylinder connected to both sides of the expansion and contraction operating body. Moreover, gripping members for electric wires are respectively attached to the free end side of the inner cylinder on both sides of an expansion-contraction operation body, and a female thread part is respectively formed in the inner peripheral surface of the base end side of an inner cylinder. To the female screw portion, coaxial screw shafts for symmetrically and simultaneously expanding and contracting the inner cylinders on both sides of the expansion and contraction operating body are screwed together. When a tool is used, the expansion and contraction rods on both sides of the expansion and contraction operating body are contracted by operating the operating shaft and screwing the screw shaft in a predetermined direction. In this way, the distance between the two gripping members for electric wires becomes small, the electric wire gripped by the two gripping members for electric wires can be loosened, and a necessary separation operation can be performed.

(First embodiment)

With reference to FIG. 1, 1 A of sleeve mounting tool in 1st Embodiment is demonstrated. 1A to 1D are schematic front views of the sleeve mounting tool 1A according to the first embodiment.

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

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

In the example shown in FIG. 1, the 1st sleeve support tool 21a which supports the end of the sleeve SV is provided in the 1st direction end of the base 2, and the 2nd of the base 2 A second sleeve support 21b for supporting the other end of the sleeve SV is provided at the end on the direction side. In the example shown in FIG. 1, although the base 2 is provided with the two sleeve supports 21a, 21b, the number of the sleeve supports with which the base 2 is equipped may be 1 or 3 or more. In addition, the arrangement|positioning of each sleeve support tool in the base 2 is not limited to the example of FIG. 1, It is arbitrary.

In the example shown in FIG. 1, the 1st core wire supporter 26a which supports the exposed core wire WC1 of the 1st electric wire W1 is provided in the 1st direction side edge part of the base part 2, and the base part 2 A second core wire supporter 26b for supporting the exposed core wire WC2 of the second electric wire W2 is provided at an end portion on the second direction side of (2). In the example shown in FIG. 1, although the base 2 is equipped with the two core wire supporters 26a, 26b, the number of the core wire support tools with which the base 2 is equipped may be three or more. In the example shown in FIG. 1, the 1st core wire supporter 26a is arrange|positioned at the 1st direction side of the sleeve support tool 21 (more specifically, the 1st sleeve support tool 21a), and the 2nd core wire The supporter 26b is arrange|positioned on the 2nd direction side of the sleeve supporter 21 (more specifically, the 2nd sleeve supporter 21b). In other words, the sleeve supporter 21 is disposed between the first core wire supporter 26a and the second core wire supporter 26b.

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

In addition, when maintaining the matching state of the central axis of the exposed core wire WC and the central axis of the sleeve SV is performed using a remote operation tool, or the sleeve holder 21 has a function of a core wire holder In such cases, the core wire support 26 may be omitted.

The first slide rod 4 is a member that is disposed on one side of the base 2 (the first direction side in the example described in FIG. 1 ) and is slidable with respect to the base 2 . As for the 1st slide rod 4, the protrusion amount from the 1st direction side edge part 20a of the base part 2 changes by operating the slide rod operation part 6. As shown in FIG. In the example described in Fig. 1, when the slide rod operating unit 6 (more specifically, the first slide rod operating unit 6a) is operated in the first operating direction R1, the first slide rod 4 moves to the base ( 2) is drawn to the side. As a result, the amount of protrusion of the first slide rod 4 from the end portion 20a on the first direction side decreases. 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 protrudes from the base 2 side in the direction Move. As a result, the amount of protrusion of the first slide rod 4 from the end portion 20a on the first direction side increases.

The second slide rod 5 is disposed on the other side of the base 2 (in the example described in FIG. 1 , the second direction side), and is a member capable of sliding with respect to the base 2 . As for the 2nd slide rod 5, the protrusion amount from the 2nd direction side edge part 20b of the base part 2 changes by operating the slide rod operation part 6. As shown in FIG. In the example described in Fig. 1, when the slide rod operating unit 6 (more specifically, the second slide rod operating unit 6b) is operated in the first operating direction R3, the second slide rod 5 moves to the base ( 2) is drawn to the side. As a result, the amount of protrusion of the second slide rod 5 from the second direction side end 20b is reduced. On the other hand, when the slide rod operation part 6 (more specifically, the second slide rod operation part 6b) is operated in the second operation direction R4, the second slide rod 5 protrudes from the base 2 side. move in the direction As a result, the amount of protrusion of the second slide rod 5 from the second direction side end 20b increases.

The slide rod operation part 6 is an operation part which slides the 1st slide rod 4 and the 2nd slide rod 5. As shown in FIG. In the example described in FIG. 1 , the slide rod operation unit 6 includes a first slide rod operation unit 6a that slides the first slide rod 4 and a second slide that slides the second slide rod 5 . A rod operation part 6b is provided. Then, the sliding movement of the first slide rod 4 and the sliding movement of the second slide rod 5 are operated independently. More specifically, when the first slide rod operating unit 6a is operated, the first slide rod 4 moves relative to the base 2 , but the second slide rod 5 moves relative to the base 2 . do not move In addition, when the second slide bar operating unit 6b 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 addition, when the sleeve mounting tool 1A has a mechanism for selectively transmitting the operating force acting on the slide rod operation unit 6 to either the first slide rod 4 or the second slide rod 5, etc. , The first slide rod operating unit 6a and the second slide rod operating unit 6b may be common.

The first electric wire gripping tool 7a grips the first electric wire W1 (more specifically, the portion WP1 in which the center line of the first electric wire W1 is not exposed). The first wire gripping tool 7a is connected to an end of the first slide rod 4 . Accordingly, when the first slide rod 4 slides with respect to the base 2 , the first wire gripper 7a moves relative to the base 2 . In the example shown in FIG. 1, 1 A of sleeve attachment tools are equipped with the 1st electric wire gripping tool 7a. In general, in a shipped state or the like, the sleeve attachment tool 1A may be configured such that the sleeve attachment tool 1A does not include the first wire gripper 7a and the sleeve attachment tool 1A is attached to the existing first wire gripper.

The second electric wire gripping tool 7b grips the second electric wire W2 (more specifically, the portion WP2 in which the center line of the second electric wire W2 is not exposed). The second wire gripping tool 7b is connected to the end of the second slide rod 5 . Accordingly, when the second slide rod 5 slides with respect to the base 2 , the second wire gripper 7b moves relative to the base 2 . In the example shown in FIG. 1, 1 A of sleeve attachment tools are equipped with the 2nd electric wire holding|gripping tool 7b. In general, in a shipped state or the like, the sleeve attachment tool 1A may be configured such that the sleeve attachment tool 1A is not provided with the second wire gripper 7b, and the sleeve attachment tool 1A is attached to the existing second wire gripper.

In the sleeve mounting tool 1A according to the first embodiment, the slide rod operation unit 6 can independently operate the sliding movement of the first slide rod 4 and the sliding movement of the second slide rod 5 . do. Therefore, when inserting the exposed core wire WC1 of the first electric wire W1 into the sleeve SV, it is enough to move the first slide rod 4 by a distance shorter than the length of the sleeve SV (Fig. 1 ( a) and 1(b)), when inserting the exposed core wire WC2 of the second electric wire W2 into the sleeve SV, the second slide rod 5 is more than the length of the sleeve SV. It may be moved by a short distance (refer to FIGS. 1(c) and 1(d)). For this reason, in the process of connecting the 1st electric wire W1 and the 2nd electric wire W2 through the sleeve SV, WHEREIN: The enlargement of the distance can be suppressed compared with the prior art. As a result, the overall slack of the first electric wire W1 and the second electric wire W2 can be suppressed.

Further, the base 2 of the sleeve mounting tool 1A in the first embodiment may be divided or bent at a substantially central portion. In the case of being able to be divided, for example, a concave portion and a convex portion are provided on one side of the divided body of the base 2 and a convex portion is provided on the other side of the divided body, and after engaging the concave and convex portions, it may be fixed with a screw or the like. Alternatively, the shape of the divided body is made 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 set with respect to the other divided body in the first direction and in the second direction. By moving in the direction perpendicular to the direction, both divided bodies may be coupled and/or separated. Moreover, what is necessary is just to join by a hinge etc. so that the base part 2 may be bent in a substantially central part, when making it bendable. Since the sleeve mounting tool 1A can be folded in two by being divided or bendable at a substantially central portion of the base 2, the sleeve mounting tool 1A can be made compact during transportation or storage.

In addition, the end of the exposed core wire WC tends to expand outward in diameter, and conventionally, it has not been easy to insert the exposed core wire WC into a 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 supporter 26, in the step of inserting the exposed core wire WC into the sleeve SV, the exposed core wire ( The seam grip between WC) and the sleeve SV can be performed easily. For this reason, the operation|work of inserting the exposed core wire WC into the sleeve opening part becomes easy. More specifically, in a state in which the sleeve SV is supported by the sleeve support 21 and the exposed core wire WC is supported by the core wire support 26 , the slide rod (first slide rod 4 or When the second slide rod (5) is drawn to the side of the base (2), the exposed core wire (WC) is automatically inserted into the sleeve (SV). For this reason, an operator can insert the exposed core wire WC into the sleeve SV easily.

(Sleeve mounting method)

With reference to FIG. 1, the sleeve attachment method in 1st Embodiment is demonstrated.

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

Fig. 1(b) shows a state after the second step ST2 is executed. In addition, 2nd step ST2 is performed by operating the slide rod operation part 6 (more specifically, the 1st slide rod operation part 6a), for example.

In the third step ST3, by moving the second slide rod 5 in a direction protruding from the base 2 side, the second wire W2 gripped by the second wire gripper 7b is removed. move in two directions. Fig. 1(c) shows a state after the third step ST3 is executed. In addition, 3rd step ST3 is performed by operating the slide rod operation part 6 (more specifically, the 2nd slide rod operation part 6b), for example.

In addition, when 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, using a remote operation tool, the exposed core wire ( The end of WC2) may be moved to a position opposite to the end of the sleeve SV in the second direction. More specifically, what is necessary is just to move the edge part of exposed core wire WC2 using a remote operation tool, and just to support the said edge part by the 2nd core wire support tool 26b.

In the fourth step ST4, by drawing the second slide rod 5 toward the base 2 side and moving the second wire W2 gripped by the second wire gripping tool 7b in the first direction, , and insert the exposed core wire WC2 of the second wire W2 into the second end of the sleeve SV. Fig. 1(d) shows a state after the fourth step ST4 is executed. In addition, 4th step ST4 is performed by operating the slide rod operation part 6 (more specifically, the 2nd slide rod operation part 6b), for example.

As described above, in the sleeve mounting method according to the first embodiment, the first electric wire W1 is exposed by a simple operation while suppressing the overall slack of the first electric wire W1 and the second electric wire W2. The sleeve SV may be mounted on the exposed core wire WC2 of the core wire WC1 and the second wire W2.

As shown in FIG. 6 : is a schematic side view which shows an example of the electric wire supporter 8. As shown in FIG. 7 is a schematic 2 side view showing an example of the sleeve cover gripping tool 9 . A front view is described on the left side of FIG. 7 , and a side view is described on the right side of FIG. 7 .

Regarding each member of the second embodiment, members having the same function as the members described in the first embodiment are given the same reference numerals as those used in the first embodiment, and the same reference numerals are assigned to the members. A repeated description will be omitted.

A sleeve mounting tool 1B according to the second embodiment includes a base 2 , a first slide rod 4 , a second slide rod 5 , and a slide rod operation unit 6 . Even if the sleeve attachment tool 1B is provided with at least one of the 1st electric wire clamping tool 7a, the 2nd electric wire clamping tool 7b, the electric wire clamping tool 8, and the sleeve cover clamping tool 9, do.

(donation(2))

In the example shown in FIG. 2 , the base 2 includes a rod-shaped portion 20 extending in the first direction, a sleeve support member 21 , a core wire support member 26 , and a slide rod operating unit 6 . to provide

In the example shown in FIG. 2, the rod-shaped part 20 is a tubular body which is provided with the 1st direction side edge part 20a and the 2nd direction side edge part 20b, and is at least partially hollow. The rod-shaped portion 20 may be made of FRP (made of fiber-reinforced plastic) or may be made of metal.

Then, with reference to FIGS. 3-5, the sleeve support tool 21 and the core wire support tool 26 are demonstrated.

In the example illustrated in FIG. 3 , the sleeve support 21 includes an attachment portion 23 attached to the rod-shaped portion 20 , and a support portion 210 for supporting the sleeve SV or the like. A through hole 231 for accommodating a part of the rod-shaped portion 20 is formed in the attaching portion 23 (refer to FIG. 4 ). The sleeve support 21 may be positioned 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. Accordingly, the versatility of the sleeve mounting tool 1B is improved. Further, the sleeve holder 21 may be detachably attached to and detached from the rod-shaped portion 20 . In this case, it becomes possible to attach the optimal sleeve holder 21 to the rod-shaped part 20 corresponding to the diameter of the sleeve SV actually used. Accordingly, the versatility of the sleeve mounting tool 1B is improved.

The support part 210 is provided with the sleeve support tool operation part 212 which changes the state of the support part between a closed state and an open state. When the support part 210 is in the closed state, the support part 210 constrains the sleeve SV, so that the sleeve SV cannot substantially move relative to the support part 210 . On the other hand, when the support part 210 is in an open state, it is possible to mount the sleeve SV on the support part 210 or to remove the sleeve SV from the support part 210 . In the example illustrated in FIG. 3 , the sleeve support operation unit 212 is an eye bolt or eye nut having a through hole capable of receiving the tip of the remote operation tool.

In the example described in FIG. 3 , the support part 210 includes a first part 214 supporting the sleeve SV and a second part 216 through which the exposed core wire WC is inserted. Moreover, in the example shown in FIG. 3, the inner surface of the 2nd part 216 is equipped with the tapered surface 216a whose diameter is reduced as it goes toward the 1st part 214. As shown in FIG. Since the second part 216 has the tapered surface 216a, even when there is an enlargement or bending at the end of the exposed core wire WC, the insertion of the exposed core wire WC into the second part 216 is smooth. is done Further, the core wire 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. It is preferable that the inner surface of the first part 214 has a cross-section support surface 214a that faces the cross-section of the sleeve SV and an outer peripheral surface support surface 214b that faces the outer peripheral surface of the sleeve SV. do.

In the example described in Fig. 3, the core wire supporter 26 includes an attachment portion 23 attached to the rod-shaped portion 20 of the base 2, and a support portion for supporting the exposed core wire WC and/or the covered wire ( 260) is provided. In the example described in FIG. 3 , the attachment portion 23 of the core wire supporter 26 and the attachment portion 23 of the sleeve supporter 21 are the same. In other words, the core wire supporter 26 and the sleeve supporter 21 share the attachment part 23 . In this case, the attachment part 23 can be attached to the rod-shaped part 20 in a state where the positional relationship between the sleeve supporter 21 and the core wire supporter 26 is maintained. In addition, like the example of FIG. 1, the attachment part of the core wire supporter 26 and the attachment part of the sleeve support tool 21 may be separate.

The support part 260 is provided with the core wire support tool operation part 262 which changes the state of a support part between a closed state and an open state. When the support part 260 is in the closed state, the support part 260 restrains the exposed core wire WC and/or the sheathed wire so that the exposed core wire WC is held against the support part 260 in a direction perpendicular to the first direction. Opponent cannot move. On the other hand, when the support part 260 is in the open state, the exposed core wire (WC) and/or the coated wire is placed on the support part 260 , or the exposed core wire (WC) and/or the coated wire is removed from the support part 260 , or it is possible to do In the example described in FIG. 3 , the core wire support operation unit 262 is an eye bolt or an eye nut having a through hole capable of receiving the tip of the remote operation tool.

It is preferable that the support part 260 is provided with the core wire receiving part 267 through which the exposed core wire WC and/or a covered electric wire are inserted. In addition, although not shown in FIG. 3, the inner surface of the core wire receiving part 267 may be equipped with the tapered surface whose diameter reduces as it goes toward the support part 210 of the sleeve SV. When the core wire accommodating part 267 has a tapered surface, insertion of the exposed core wire WC into the core wire accommodating part 267 is performed smoothly.

In the example described in FIG. 3 , a gap G is provided between the support part 260 of the core wire supporter 26 and the support part 210 of the sleeve supporter 21 . By the existence of the gap G, the operator can confirm whether or not the exposed core wire WC inserted from the core wire supporter 26 side has reached the sleeve supporter 21 .

Moreover, when the sleeve mounting tool 1B in 2nd Embodiment is provided with the at least one sleeve cover gripper 9, the movement of the sleeve cover SC is prevented. For this reason, the sleeve cover SC does not interfere during the operation|work of inserting an exposed core wire into the sleeve SV, or the operation|work of compressing the sleeve SV. In addition, the structure of the electric wire holding tool 8 and/or the sleeve cover holding tool 9 in 2nd Embodiment may be employ|adopted in 1st Embodiment.

(Sleeve mounting method)

An example of the sleeve mounting method in 2nd Embodiment is demonstrated with reference to FIGS. 8-17. 8 is a flowchart showing an example of the sleeve mounting method according to the second embodiment. Each of FIGS. 9-17 is a figure which shows one process of a 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 wire gripping tool 7a and the second wire gripping tool 7b to the electric wire W. In the example described in Fig. 9, the sleeve mounting tool 1B is attached to the electric wire W so as to face the portion where the core wire WC is exposed (exposed portion A) in which the coating layer of the electric wire W is peeled off. is attached. 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 supporter 8 (specifically, the first electric wire supporter 8a and the second electric wire supporter 8b). do. In the step of supporting the electric wire W by the electric wire supporter 8, for example, the opening and closing members 82a, 82b are moved to the open position, and the electric wire W is moved in the frame members 81a, 81b. and, thereafter, by moving the opening/closing members 82a and 82b to the closed position. In addition, the process of supporting the electric wire W by the electric wire holding tool 8, and the process of attaching the 1st electric wire gripping tool 7a and the 2nd electric wire gripping tool 7b to the electric wire W, which You may perform the above process first.

In the second step ST102, the slide rod operating unit 6 (eg, the first slide rod operating unit 6a) is operated to draw the first slide rod 4 to the base 2 side, and the slide rod It is performed by operating the operation part 6 (for example, the 2nd slide rod operation part 6b), and drawing the 2nd slide rod 5 to the base 2 side. In addition, as for the drawing-in process of the 1st slide rod 4 and the drawing-in process of the 2nd slide rod 5, either process may be performed first. In general, the drawing-in step of the first slide bar 4 and the drawing step of the second slide bar 5 may be alternately and repeatedly performed.

In the third step ST103, between the first wire gripping tool 7a and the second wire gripping tool 7b, the wire W is cut by the cutting tool. By the said cutting|disconnection, the electric wire W is separated into the 1st electric wire W1 and the 2nd electric wire W2. Moreover, it is preferable that a cutting position is the part (exposed part A) in which the center line WC of the electric wire W is exposed. In this case, 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 by cutting. In addition, instead of peeling off the coating layer of an electric wire before cutting|disconnection of an electric wire, you may make it peel off after cutting|disconnecting an electric wire, the coating layer of the edge part of the 1st electric wire W1 and the edge part of the 2nd electric wire W2. 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 a cutting tool attached to the front-end|tip of a remote control tool, for example. 11 shows the state after the third step ST103 is executed.

As shown in FIG. 12, in 4th step ST104, the edge part of the 1st electric wire W1 and the edge part of the 2nd electric wire W2 are divided (for example, it is divided 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 supporter 8b toward the third electric wire supporter 8c, and the second electric wire W2 is It is carried out by supporting the end of the wire by the third wire supporter (8c). Alternatively, the fourth step ST104 may be executed by rotating the second electric wire support 8b supporting the end of the second electric wire W2 about the longitudinal axis of the base 2 .

In the fourth step (ST104), additionally, 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 rod 4 and/or the second The two slide rods 5 may be moved in a direction protruding from the base 2 . The movement is performed by operating the slide rod operating unit 6 (specifically, the first slide rod operating unit 6a and/or the second slide rod operating unit 6b).

After execution of the fourth step ST104, an insulating cap IC (refer to Fig. 13) may be attached to one of the end of the first electric wire W1 and the end 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.

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

13, in the fifth step (ST105), the first sleeve cover SC1 is pushed in so that the first electric wire W1 passes through the inside of the first sleeve cover SC1, and thereafter, The first sleeve cover SC1 is gripped by the first sleeve cover gripper 9a. The fifth step ST105 is executed using, for example, a remote operation tool such as insulated pliers.

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 fifth step ST105 is executed. Moreover, as shown by the arrow B, before execution of 5th step ST105, the 1st slide rod 4 may be moved in the direction which protrudes from the base part 2 .

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 mounted on the sleeve holder 21 using a remote operation tool such as insulating pliers. Then, by using the remote operation tool, the sleeve holder operation unit 212 is operated to change the state of the sleeve holder 21 from the open state to the closed state. As a result, the sleeve SV is positioned and supported by the sleeve support 21 . Moreover, when the sleeve support tool 21 includes the 1st sleeve support tool 21a and the 2nd sleeve support tool 21b, the sleeve SV is the 1st sleeve support tool 21a and the 2nd sleeve support tool 21a. Positioning is supported by the sleeve support 21b.

As shown in FIG. 13, in 7th step ST107, the exposed core wire WC1 of the 1st electric wire W1 is supported by the 1st core wire supporter 26a. In the seventh step ST107, first, the exposed core wire WC1 is moved into the first core wire supporter 26a using a remote operation tool. Thereafter, the first core wire supporter operation unit 262a is operated using the remote operation tool to change the state of the first core wire supporter 26a from the open state to the closed state. As a result, the exposed core wire WC1 is restrained by the first core wire supporter 26a. By this restraint, the bending property of the 1st electric wire W1 is corrected while seam grabbing between the sleeve SV and the exposed core wire WC1 is performed. As a result, the subsequent process (the process of inserting the exposed core wire WC1 into the sleeve SV) is performed 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 rod operating unit 6 (eg, the first slide rod operating unit 6a) to draw the first slide rod 4 to the base 2 side. do. By executing the eighth step ST108, the downward bending of the first electric wire W1 and the second electric wire W2 is reduced. Moreover, by execution of 8th step ST108, 1st sleeve cover SC1 approaches the 1st core wire supporter 26a.

The first sleeve cover SC1 gripped by the first sleeve cover gripper 9a also functions as a restraint for holding the first electric wire W1 in a linear shape. Therefore, when the sleeve mounting tool 1B is provided with the 1st sleeve cover gripping tool 9a, the process 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 to the base ( 2) is moved in the protruding direction. By execution of 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. Further, by executing the ninth step ST109, the downward bending of the first electric wire W1 and the second electric wire W2 is increased.

In addition, 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 ninth step ST109 is executed.

In the tenth step (ST110), the second sleeve cover (SC2) is pushed so that the second 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 using, for example, a remote operation tool such as insulating pliers. In addition, 10th step ST110 is performed after moving the edge part of the 2nd electric wire W2 above the 2nd slide rod 5. As shown in FIG. The movement of the end of the second electric wire W2 includes, for example, displacing the end of the second electric wire W2 from the inside of the third electric wire support 8c into the second electric wire supporter 8b.

In the eleventh step ST111, the exposed core wire WC2 of the second wire W2 is supported by the second core wire supporter 26b. In the eleventh step ST111, first, the exposed core wire WC2 is moved in the second core wire supporter 26b using a remote operation tool. Thereafter, the second core wire supporter operation unit 262b is operated using the remote operation tool to change the state of the second core wire supporter 26b from the open state to the closed state. As a result, the exposed core wire WC2 is restrained by the second core wire supporter 26b. By this restraint, the bending property of the 2nd electric wire W2 is corrected while seam grabbing between the sleeve SV and the exposed core wire WC2 is performed.

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 (eg, the second slide rod operating unit 6b) to draw the second slide rod 5 to the base 2 side. do. By executing the twelfth step ST112, the downward bending of the first electric wire W1 and the second electric wire W2 is reduced. Moreover, by execution of 12th step ST112, 2nd sleeve cover SC2 approaches the 2nd core wire supporter 26b.

The second sleeve cover SC2 gripped by the second sleeve cover gripper 9b also functions as a restraint for holding the second electric wire W2 in a linear shape. Therefore, when the sleeve mounting tool 1B is provided with the 2nd sleeve cover gripper 9b, the process of inserting the exposed core wire WC2 into the sleeve SV is performed more smoothly.

After execution of the twelfth step ST112, restraint on the sleeve SV by the sleeve supports 21a, 21b, restraint on the exposed core wire by the core wire supporters 26a, 26b, and the sleeve cover gripper The restraint on the sleeve cover by (9a, 9b) may be released or reduced. The release or reduction of these restraints is performed by operating the sleeve holder operation unit 212 , the core wire holder operation unit 262 , and the sleeve cover holder operation unit 952 with a remote operation tool. When the first slide rod 4 and/or the second slide rod 5 are drawn to the base 2 side in a state in which these restraints are released or reduced, the exposed core wire WC1 and the exposed core wire WC2 are It is inserted to a deeper position of the sleeve SV. And, 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 a thirteenth step ST113, the sleeve mounting tool 1B is removed from the first electric wire W1 and the second electric wire W2.

In step 14 (ST114), the first sleeve cover (SC1) and the second sleeve cover (SC2) are moved to a position covering the sleeve (SV), so that the first sleeve cover (SC1) and the second sleeve cover (SC2) ) is connected.

It is clear that this invention is not limited to each said embodiment, Within the scope of the technical idea of this invention, each embodiment can be suitably modified or changed. Moreover, it is possible to combine arbitrary components used by each embodiment with another embodiment, and it is also possible to abbreviate|omit arbitrary components in each embodiment.

For example, in the example shown in FIG. 1 or FIG. 2, the slide rod operation part 6 includes the 1st slide rod operation part 6a which slides the 1st slide rod 4, and the 2nd slide rod 5. An example including the second slide rod operation unit (6b) for sliding the has been described. In general, as shown in FIG. 18 , one slide rod operation unit 6c may independently operate each of the first slide rod 4 and the second slide rod 5 .

In the example described in FIG. 18 , the slide rod operation unit 6c is a first load transmission mechanism 61 for driving the first slide rod 4 , or a second load transmission mechanism for driving the second slide rod 5 . To the instrument 62 , it is selectively connectable. More specifically, the slide bar operation unit 6c includes an operation unit side engaging portion 63 , and the first load transmission mechanism 61 includes a first engaging portion engageable with the operation unit side engaging portion 63 . The engaging part 61a is provided, and the 2nd load transmission mechanism 62 is provided with the 2nd engaging part 62a engageable with the operation part side engaging part 63. FIG. And the operation part side engagement part 63 is selectively engaged with the 1st engagement part 61a or the 2nd engagement part 62a. In this way, the operating force acting on the slide rod operation part 6c is applied to the first slide rod 4 or the second slide rod 5 via the first engagement part 61a or the second engagement part 62a. ) can be optionally passed to.

In the example described in FIG. 18 , the slide rod operation part 6c is attached to the base 2 so as to be movable relative to the base 2 . An elastic urging member 64 is interposed between the slide rod operating part 6c and the base 2, and the elastic urging member 64 engages the slide rod operating part 6c with the first engaging part 61a. ) or in a direction toward the second engaging portion 62a. Moreover, in the example described in FIG. 18, the magnet 65 which is attracted|sucked by the 1st engagement part 61a (or the 2nd engagement part 62a) is arrange|positioned in the operation part side engagement part 63. As shown in FIG. Alternatively or additionally, a magnet for attracting the operation unit side engaging portion 63 may be disposed 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 includes a first bevel gear 61b that rotates together with the first engaging portion 61a and a first slide rod 4 that is screwed into the screw. It is provided with the 2nd bevel gear 61e which rotates together with the 1st screw rod 61c. For this reason, when the slide rod operation part 6c is operated so that it may rotate around the 1st axis AT1, the 1st engagement part 61a engaged with the operation part side engagement part 63 is the 1st bevel gear 61b and rotates around the first axis AT1. In the example shown in FIG. 18, the 1st bevel gear 61b and the 2nd bevel gear 61e mesh with each other. Accordingly, when the first bevel gear 61b rotates around the first shaft AT1, the second bevel gear 61e meshed with the first bevel gear 61b together with the first screw rod 61c , rotates around the second axis AT2 perpendicular to the first axis AT1 . The threaded portion 61d of the first screw rod 61c is screwed into the first slide rod 4 . For this reason, when the 1st screw rod 61c rotates around 2nd axis AT2, the 1st slide rod 4 slides in the direction along 2nd axis AT2.

Similarly, in the example described in FIG. 18 , the second load transmission mechanism 62 is screwed to the third bevel gear 62b which rotates together with the second engagement portion 62a and the second slide rod 5 . A fourth bevel gear 62e is provided which rotates together with the second screw rod 62c to be engaged. For this reason, when the slide rod operation part 6c is operated so that it may rotate around the 3rd axis AT3, the 2nd engagement part 62a engaged with the operation part side engagement part 63 is the 3rd bevel gear 62b. and rotates around the third axis AT3. In the example described in Fig. 18, the third bevel gear 62b and the fourth bevel gear 62e mesh with each other. Accordingly, when the third bevel gear 62b rotates around the third axis AT3, the fourth bevel gear 62e meshed with the third bevel gear 62b together with the second screw rod 62c , rotates around the fourth axis AT4 perpendicular to the third axis AT3. The threaded portion 62d of the second screw rod 62c is screwed into the second slide rod 5 . For this reason, when the 2nd screw rod 62c rotates around 4th axis AT4, the 2nd slide rod 5 slides in the direction along 4th axis AT4. In addition, the fourth axis AT4 and the second axis AT2 are axes arranged on a straight line.

In the example shown in FIG. 18, when the engagement target of the operation part side engaging part 63 of the slide rod operation part 6c is switched from the 1st engagement part 61a to the 2nd engagement part 62a assume In this case, first, using a remote operation tool, the slide rod operation part 6c is moved against the elastic pressing force by the elastic pressing member 64 and/or the attraction force by the magnet 65 to resist the first engaging portion ( 61a) and move it in a direction away from it. Next, using a remote operation tool, the slide rod operation part 6c is slid from the position opposing the 1st engaging part 61a to the position opposing the 2nd engaging part 62a. The base 2 is preferably provided with a guide portion such as an elongated hole for guiding the sliding movement of the slide rod operation portion 6c. Then, the slide bar operation part 6c is engaged with the 2nd engagement part 62a by the elastic urging force by the elastic urging member 64 and/or the adsorption|suction force by the magnet 65. As shown in FIG.

The operation of switching the engagement target of the engaging portion 63 on the operation portion side of the slide rod operation portion 6c from the second engagement portion 62a to the first engagement portion 61a is performed by the slide rod operation portion 6c.

A grip member 23b that is relatively movable with respect to each other is provided. When the grip member 23b is in the grip position with respect to the attachment part base member 23a, the attachment part 23 is fixed to the rod-shaped part 20 by the grip member 23b and the attachment part base member 23a. do. 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 is detached from the rod-shaped portion 20 (or the attachment portion 23 ) attached to the rod-shaped part 20) is possible.

In the example shown in Fig. 19, the grip member 23b is pivotably attached to the attachment base member 23a, and the grip member 23b has a first pivoting axis ( AS1) Freely oscillate around. 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 for suppressing sliding with respect to the rod-shaped part 20 may be disposed on the inner surface of the attachment part base member 23a. Similarly, on the inner surface of the grip member 23b, an elastic body 24b for suppressing sliding with respect to the rod-shaped portion 20 may be disposed.

In the example shown in FIG. 19, the magnet 235 for holding the grip member 23b in the grip position is arrange|positioned in the grip member 23b. The magnet 235 is attracted by the attachment part 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 described in FIG. 19 , the attachment portion 23 includes a lock member 25 that prevents the grip member 23b from moving from the grip position toward the grip open position. The lock member 25 is swingably attached to the attachment part base member 23a, for example. In the example described in FIG. 19 , the lock member 25 freely swings around the second swing shaft 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 23a is disposed 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 attachment portion 23 is attached to the rod-shaped portion 20 . Subsequently, by moving the locking member 25 from the unlocked position to the locked position, the gripping member 23b is locked so as not to move from the gripping position.

When the attachment portion 23 is detached 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 described in FIG. 19 , the attachment portion 23 includes an attachment portion base member 23a and a grip member 23b. For this reason, the attachment part 23 can be attached to the rod-shaped part 20 of the base 2 by simple operation, and the attachment part 23 can be attached to the rod-shaped part of the base 2 by a simple operation. It can be removed from (20). In addition, the attachment part 23 can be attached to the rod-shaped part 20 with a simple operation. means that In this case, the attachment position of the attachment part 23 with respect to the rod-shaped part 20 can be easily adjusted according to the length etc. of the sleeve SV to be used.

FIG. 20 shows a modified example of the opening/closing operation mechanism M for opening and closing at least one of the sleeve support 21 and the core wire support 26 . In the example shown in FIG. 4 or FIG. 5, opening and closing of the sleeve support tool 21 or the core wire support tool 26 was performed by rotating the operation parts 212; 262, such as an eye bolt and an eye nut. On the other hand, in the example described in FIG. 20, the opening and closing of the sleeve support tool 21 or the core wire support tool 26 is performed by the swing type operation levers 212a; 262a. The operation levers 212a; 262a are, for example, toggle levers.

With reference to FIG. 20, an example of the mechanism by which the sleeve support tool 21 or the core wire support tool 26 is opened and closed by the swing type operation levers 212a; 262a is demonstrated.

In the example described in Fig. 20, when the operating levers 212a; 262a are in the first position (for example, the upper position), the supports 21; 26 are in the open state. In the example of FIG. 20, the open state of the support tools 21; 26 means the state in which the 1st divided body 218a; 268a and the 2nd divided body 218b; 268b were spaced apart. In the example described in Fig. 20, when the operating levers 212a; 262a are in the second position (for example, the lower position), the supports 21; 26 are in the closed state. In the example of FIG. 20, the closed state of the support tools 21; 26 means the state in which the 1st divided body 218a; 268a and the 2nd divided body 218b; 268b were adjacently arrange|positioned.

In the example described in FIG. 20, when the operation lever 212a; 262a moves from the 1st position (upper position) to the 2nd position (lower position), the 1st pressing body 27a, The first divided body 218a; 268a is pressed in the direction to the second divided body, and the second pressing body 27b presses the second divided body 218b; 268b in the direction to the first divided body. . In this way, the supports 21; 26 are in the closed state.

In the example described in FIG. 20, the elastic pressing member 28 is arrange|positioned between the 1st divided body 218a; 268a, and the 2nd divided body 218b; 268b. The elastic pressing member 28 is a direction in which the first divided body 218a; 268a and the second divided body 218b; 268b are spaced apart from each other, and the first divided body 218a; 268a and the second divided body 218b are separated from each other. ; 268b) is elastically pressed. For this reason, when the operation lever 212a; 262a moves from the 2nd position (lower position) to the 1st position (upper position), the elastic pressure member 28 releases the 1st divided body 218a; 268a, It presses in the direction away from 2 division body, and the elastic pressure member 28 presses 2nd division body 218b; 268b in the direction away from a 1st division body. In this way, the supports 21; 26 are in an open state.

In the example described in FIG. 20, the 1st shaft 29a to which the 1st pressing body 27a was fixed is pivotally attached to the 1st pin 29c attached to the operation lever 212a; 262a. Moreover, the 2nd pressing body 27b slides freely along the longitudinal direction of the 1st shaft 29a, and the 2nd pressing body 27b is the operation lever 212a through the connecting member CN; 262a) is attached. More specifically, the connecting member CN is pivotally attached to the second pressing body 27b via the second pin 29d, and is further attached to the second pressing body 27b via the third pin 29e, It is attached to the operation lever 212a; 262a so that a pivotal movement is possible.

In the example described in Fig. 20, when the operating levers 212a; 262a move from the first position (upper position) to the second position (lower position), the operating levers 212a; 262a move the third pin 29e. When the periphery is rotated, the first fin 29c rotates around the third fin 29e. As a result, the 1st shaft 29a connected to the 1st pin 29c and the 1st pressing body 27a move in the direction approaching the 2nd pressing body 27b. In this way, the supports 21; 26 are in the closed state.

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

More specifically, the 1st divided body 218a; 268a is equipped with the engaging part EN1 engageable with a positioning stopper. For this reason, the 1st divided body 218a; 268a cannot move beyond the positioning stopper to the 2nd divided body side. Moreover, the 2nd divided body 218b; 268b is equipped with the engaging part EN2 engageable with a positioning stopper. For this reason, the 2nd divided body 218b; 268b cannot move to the 1st divided body side beyond the positioning stopper. In this way, the 1st divided body 218a; 268a and the 2nd divided body 218b; 268b are the position where the positioning stopper is arrange|positioned, and come into contact with each other.

In addition, the toggle clamp (product number: MC02-S2) made by MISUMI Corporation may be used for the opening/closing operation mechanism M.

In the example described in FIG. 20, the support tools 21; 26 are opened and closed by the swinging operation levers 212a; 262a. Therefore, the support tools 21; 26 can be easily opened and closed using a remote operation tool.

Using the sleeve mounting tool and the sleeve mounting method of the present invention, the sleeve ( SV) can be installed. Therefore, it is useful for a manufacturer of a sleeve mounting tool and a person who performs a sleeve mounting operation.
