  The first rod member 3 is connected to the first electric wire holder 2. The connection between the first rod member 3 and the first wire gripper 2 may be a connection that can swing about an axis perpendicular to the X direction, or a connection that cannot swing.

  The first rod member 3 includes a base part 30 and a moving part 32. The first rod member 3 can be expanded and contracted when the moving section 32 moves relative to the base section 30. The first bar member 3 includes a connection mechanism (gear mechanism, screw mechanism, etc.) for connecting the base portion 30 and the moving portion 32 so as to be relatively movable. It expands and contracts by operating the unit 300. The operation of the operation unit 300 is performed using, for example, a remote control tool. The first rod member 3 is made of, for example, FRP (made of fiber reinforced plastic). The cross-sectional shape of the first rod member 3 (the base portion 30 and the moving portion 32) is not particularly limited as long as the base portion 30 and the moving portion 32 can move relative to each other. Just choose.

  The second wire gripper 4 grips a second portion of the wire W. The second electric wire gripper 4 includes, for example, a first gripping piece 41 and a second gripping piece 42, and holds the second portion of the electric wire W between the first gripping piece 41 and the second gripping piece 42.

  The second rod member 5 is connected to the second wire gripper 4. The connection between the second rod member 5 and the second wire gripper 4 may be a connection that can swing about an axis perpendicular to the X direction, or a connection that cannot swing. The second rod member 5 is made of, for example, FRP (made of fiber reinforced plastic).

  In the example illustrated in FIG. 1, the second bar member 5 includes a retaining portion 5a. The second bar member 5 is prevented from being completely separated from the first bar member 3 (more specifically, the base portion 30) by the retaining portion 5a.

  The first connecting member 60 connects the first rod member 3 (more specifically, the moving portion 32 of the first rod member 3) and the second rod member 5 so as to be relatively movable. More specifically, the moving part 32 of the first rod member 3 and the second rod member 5 are connected via the first connecting member 60, and the moving part 32 of the first rod member 3 is connected to the second rod member 3. 5 can be slid in the X direction or the −X direction. The cross-sectional shape of the second rod member 5 is not particularly limited as long as the second rod member 5 can move relative to the first rod member 3 via the first connecting member 60, and may be appropriately selected from a circle, an ellipse, a polygon, and a hemisphere. Good.

  The first connecting member 60 is provided on the moving part 32 of the first rod member 3. In the example illustrated in FIG. 1, the first coupling tool 60 is fixed to the distal end of the moving unit 32.

  In the example shown in FIG. 1, the first connecting member 60 has a hole 61, and the second rod member 5 is inserted into the hole 61. The first connector 60 is made of, for example, plastic.

  The movement restricting member 7 restricts relative movement of the first rod member 3 with respect to the second rod member 5 (more specifically, relative movement of the moving portion 32 of the first rod member 3 with respect to the second rod member 5). It is. In the example shown in FIG. 1, the movement restricting member 7 </ b> A restricts the relative movement of the first rod member 3 with respect to the second rod member 5 and the relative movement of the first rod member 3 with respect to the second rod member 5. It takes one of the allowable states. In the restricted state, the second bar member 5 moves together with the moving part 32 of the first bar member 3. On the other hand, in the allowable state, the moving portion 32 of the first bar member 3 moves independently of the second bar member 5.

  In the example shown in FIG. 1, the state in which the movement restricting member 7A supported by the first connecting member 60 is in contact with the second rod member 5 (the state in which the movement restricting member 7 is pushed in) is the restricted state, and the first state is shown in FIG. The state in which the movement restricting member 7A supported by the connecting member 60 is separated from the second rod member 5 is an allowable state. Switching from the restricted state to the permitted state or from the permitted state to the restricted state is performed by operating the operation unit 70A of the movement restriction member 7A.

  In the example shown in FIG. 1, the movement restricting member 7 </ b> A is a male screw member that is screwed into a female screw provided on the first connecting member 60. However, the shape, arrangement, and structure of the movement restricting member 7A are not limited to the example shown in FIG.

  The first wire support 80 moves together with the moving portion 32 of the first rod member 3. In the example illustrated in FIG. 1, the first wire support 80 is supported by the moving unit 32 via the first connector 60. Alternatively, the first wire support 80 may be directly supported (that is, fixed) on the moving unit 32. The first wire support 80 is capable of supporting (fixing) the first cut end Wa of the wire W. Details will be described later.

(Electric wire cutting method)
The electric wire cutting method according to the first embodiment will be described with reference to FIGS. FIG. 2 is a flowchart illustrating an example of the electric wire cutting method according to the first embodiment. FIGS. 1, 3 to 6 are views schematically showing one step of the electric wire cutting method according to the first embodiment.

  In the first step ST1, the first wire gripper 2 is attached to the wire W. In the second step ST2, the second electric wire holder 4 is attached to the electric wire W. Note that the second step ST2 may be executed after the first step ST1, or may be executed before the second step ST2. FIG. 1 shows a state of the electric wire operating tool 1A after executing the first step ST1 and the second step ST2.

  In the third step ST3, the wire W is bent by reducing the distance between the first wire gripper 2 and the second wire gripper 4 (see FIG. 3). The third step ST3 can be executed by contracting the first rod member 3. The contraction of the first bar member 3 is executed in a restricted state in which the relative movement of the first bar member 3 with respect to the second bar member 5 is restricted.

  In the fourth step ST4, the electric wire W is cut at a position between the first electric wire gripping tool 2 and the second electric wire gripping tool 4 (for example, a position indicated by an arrow A in FIG. 3). By cutting the wire W, a first cut end Wa and a second cut end Wb are formed on the wire W (see FIG. 4).

  In the fifth step ST5, the first cut end Wa formed by cutting the wire W is fixed to the first wire support 80. The fixing is performed, for example, by clamping the first cut end Wa between the first gripping piece 801 of the first wire support 80 and the second gripping piece 802 of the first wire support 80.

  Subsequently, the state of the movement restricting member 7A is changed from the restricted state to the permitted state. That is, by operating the operation unit 70A, the state of the movement restricting member 7A changes the relative movement of the first rod member 3 (more specifically, the moving part 32 of the first rod member 3) with respect to the second rod member 5. Is changed to a permissible state.

  A tension acts on the first rod member 3 and the second rod member 5 by the electric wire W gripped by the first wire gripper 2 and the second wire gripper 4. For this reason, when the state of the movement restricting member 7A is changed from the restricted state to the allowable state, the first rod member 3 (more specifically, the moving portion 32 of the first rod member 3) becomes the second rod member 5. (See FIGS. 4 and 5). When the state of the movement restricting member 7A is changed from the restricted state to the allowable state, the first rod member 3 relatively moves with respect to the second rod member 5, and an impact force may act on the retaining portion 5a. There is. Therefore, in order to reduce the impact force, a buffer member such as an elastic member is interposed between the first rod member 3 and the second rod member 5 (more specifically, the retaining portion 5a). You may.

  In the sixth step ST6, by moving the first rod member 3 (more specifically, the moving part 32 of the first rod member 3) relative to the second rod member 5, the first cut end Wa and the first cut end Wa can be moved. Then, the second cut end Wb formed by cutting the electric wire W is separated (see FIG. 6). Thus, the distance between the first cut end Wa and the second cut end Wb increases, and the first cut end Wa and the second cut end Wb are separated.

  The sixth step ST6 can be executed by contracting the first rod member 3. The contraction of the first rod member 3 is executed in an allowable state in which the first rod member 3 (more specifically, the moving portion 32 of the first rod member 3) is allowed to move relative to the second rod member 5. You.

  In the first embodiment, the electric wire is bent by contracting the first rod member 3 (third step ST3), and the first cutting end Wa and the second cutting end are contracted by contracting the first rod member 3. The distance to Wb is increased (sixth step ST6). For this reason, as in the example described in Patent Literature 1, in order to increase the distance between the first cut end and the second cut end, the wire support that supports the first cut end can be expanded and contracted. There is no need to rotate 180 degrees around a perfect bar.

  As described above, in the electric wire cutting method according to the first embodiment, the work load on the worker is reduced, and the worker can safely and efficiently perform the cutting work on the electric wire. In the first embodiment, a step of rotating the first wire support 80 around the first rod member 3 may be added as necessary. However, this step is indispensable in the first embodiment. It is not a process.

  The electric wire operating tool 1A according to the first embodiment may be used to execute the electric wire cutting method described above. That is, the worker can safely and efficiently perform the wire cutting operation using the wire operating tool 1A according to the first embodiment.

(Wire connection method)
The electric wire connection method in the first embodiment will be described with reference to FIGS. FIG. 2 is a flowchart illustrating an example of the electric wire connection method according to the first embodiment. FIG. 7 is a schematic side view schematically illustrating one step of the electric wire connection method according to the first embodiment.

  Before the execution of the electric wire connection method, the insulation coating is removed at the first end (first cut end Wa) of the first electric wire W1 and the second end (second cut end Wb) of the second electric wire W2. The core of the electric wire W is exposed at the first end (Wa) and the second end (Wb).

  In the seventh step ST7, the second end (Wb) of the second electric wire W2 held by the second electric wire holder 4 is inserted into the second end Sb of the connection sleeve SV (see FIG. 7). Note that the seventh step ST7 is executed, for example, after the sixth step ST6 of the above-described wire cutting method.

  In the eighth step ST8, by moving the first rod member 3 (more specifically, the moving portion 32 of the first rod member 3) relative to the second rod member 5, the first wire support member 80 The first end (Wa) of the fixed first electric wire W1 is inserted into the first end Sa of the connection sleeve SV. Thus, the first end (Wa) of the first electric wire W1 and the second end (Wb) of the second electric wire W2 are connected via the connection sleeve SV. After the eighth step ST8, even if the connection sleeve SV is crimped, the connection sleeve SV and the first end (Wa) are crimped, and the connection sleeve SV and the second end (Wb) are crimped. Good.

  The eighth step ST8 can be executed by extending the first rod member 3. The extension of the first bar member 3 is executed in an allowable state in which the relative movement of the first bar member 3 (more specifically, the moving portion 32 of the first bar member 3) with respect to the second bar member 5 is allowed. You.

  In the first embodiment, the first end (Wa) of the first electric wire W1 can be inserted into the connection sleeve SV only by extending the first rod member 3. Therefore, the work load when inserting the first end (Wa) into the connection sleeve SV is greatly reduced. Further, when inserting the first end portion (Wa) into the connection sleeve SV, the operator is not required to have an unreasonable posture or difficult movement. For this reason, the worker can safely and efficiently perform the wire connection work.

  In the electric wire connection method according to the first embodiment, after the electric wire W is cut, the moving unit 32 is simply moved without changing the distance between the first electric wire gripper 2 and the second electric wire gripper 4. Thus, the first end (Wa) of the first electric wire W1 can be moved. For this reason, the tension acting on the electric wire W gripped by the first wire gripper 2 or the second wire gripper 4 due to the change in the distance between the first wire gripper 2 and the second wire gripper 4. Does not change, and the amount of bending of the electric wire W does not change. Further, since the first end (Wa) of the first electric wire W1 can be moved without changing the distance between the first electric wire gripping tool 2 and the second electric wire gripping tool 4, the work is performed. The amount of deflection below the middle electric wire W can be reduced. As a result, the risk of the working wire interfering with other wires is reduced. Therefore, it is possible to stably and safely move the first end (Wa) of the first electric wire W1 to connect the electric wire.

  The electric wire operating tool 1A according to the first embodiment may be used to execute the electric wire connection method described above. That is, the worker can safely and efficiently perform the connection work of the electric wires using the electric wire operation tool 1A according to the first embodiment.

(Modification of First Embodiment)
With reference to FIG. 8, a modified example of the electric wire operating tool 1A according to the first embodiment will be described. FIG. 8 is a schematic side view of the electric wire operating tool 1A according to the first embodiment (modification).

  As shown in FIG. 8, the electric wire operating tool 1A may include a second electric wire support 82. In the example illustrated in FIG. 8, the second wire support 82 is supported (that is, fixed) by the second rod member 5. The second wire support 82 can support the second end (second cut end Wb) of the wire W.

  In a modified example, the electric wire operating tool 1A includes a second electric wire support 82 that can support the second end of the electric wire W. When the electric wire operating tool 1A includes the second electric wire support 82, the second cut end Wb of the electric wire W is suitably positioned after cutting the electric wire W. Further, after cutting the electric wire W, the sag (bending) of the second electric wire W2 is suppressed. For this reason, the work of inserting the second end (Wb) of the second electric wire W2 into the connection sleeve SV becomes easy.

  The step of supporting the wire W on the second wire support 82 (for example, the step of fixing the wire W to the second wire support 82) may be performed before the first step ST1 and the second step ST2. Then, it may be executed between the first step ST1 and the second step ST2, or may be executed after the first step ST1 and the second step ST2. The step of supporting the electric wire W on the second electric wire support member 82 (for example, the step of fixing the electric wire W to the second electric wire support member 82) may be performed before the fourth step ST4, or may be performed in the fourth step. It may be executed after ST4.

  In the example shown in FIG. 8, the number of the wire supports (80, 82) is two, but the number of the wire supports may be three or more.

  As shown in FIG. 8, the electric wire operating tool 1A may include a sleeve support member 90 that detachably supports the connection sleeve SV. The sleeve support member 90 is fixed to, for example, the second bar member 5 and is supported by the second bar member 5. When the electric wire operation tool 1A includes the sleeve support member 90, the operation of inserting the first end (Wa) of the first electric wire W1 into the connection sleeve SV becomes easy. For example, when inserting the first end (Wa) of the first electric wire W1 into the connection sleeve SV, the operator does not need to support the connection sleeve SV using a remote control tool.

  The step of causing the sleeve support member 90 to support the connection sleeve SV may be performed before the first step ST1 and the second step ST2, or may be performed after the first step ST1 and the second step ST2. Good. The step of causing the sleeve support member 90 to support the connection sleeve SV may be performed before the seventh step ST7, or may be performed after the seventh step ST7.

  The configuration of the above-described sleeve support member 90 may be employed in an electric wire operating tool 1B according to a second embodiment described later.

(Second embodiment)
With reference to FIGS. 9 to 11, an electric wire operating tool 1B according to the second embodiment will be described. FIG. 9 is a schematic side view of an electric wire operating tool 1B according to the second embodiment. FIG. 10 is a schematic plan view of an electric wire operating tool 1B according to the second embodiment. In FIG. 10, the description of the first wire gripper 2 and the second wire gripper 4 is omitted. FIG. 11 is a schematic front view schematically showing the electric wire support (80, 82, 84).

  The electric wire operation tool 1 </ b> B according to the second embodiment is different from the electric wire operation tool 1 </ b> B in that the movement restricting member 7 includes a first stopper 71 that restricts relative movement of the moving portion 32 of the first rod member 3 with respect to the second rod member 5. It is different from the electric wire operating tool 1A in the embodiment. In the second embodiment, the points different from the first embodiment will be mainly described, and the repeated description of the items already described in the first embodiment will be omitted.

  The electric wire operating tool 1B includes a first electric wire gripper 2, a first rod member 3 connected to the first electric wire gripper 2, a second electric wire gripper 4, and a second electric wire gripper 4 connected to the second electric wire gripper 4.

The first electric wire gripper 2 is connected to the base 30 of the first rod member 3 via the first connecting portion 24.

(1st rod member 3)
The first rod member 3 includes a base part 30 and a moving part 32. The first rod member 3 can be expanded and contracted when the moving section 32 moves relative to the base section 30. The first bar member 3 includes a connection mechanism (gear mechanism, screw mechanism, etc.) for connecting the base portion 30 and the moving portion 32 so as to be relatively movable. It expands and contracts by operating the unit 300.

  An example of a mechanism for extending and retracting the extendable first rod member 3 using a remote control tool will be described. As an example, (A) the operation unit 300 is provided with a first bevel gear that rotates around the rotation axis R1 together with the operation unit, and (B) the inside of the base unit 30 is capable of transmitting a load to the first bevel gear. The connected second bevel gear is arranged, and (C) the second bevel gear rotates around the longitudinal axis L1 of the first rod member 3 together with a screw rod having an outer thread arranged on the outer periphery, and (D) It is assumed that the moving unit 32 is screwed to the screw bar. In this case, when the operation unit 300 is rotated around the rotation axis R1 by the remote operation member, the first bevel gear rotates around the rotation axis R1, and the second bevel gear rotates around the longitudinal axis L1. When the second bevel gear rotates around the longitudinal axis L1, the threaded bar rotates around the longitudinal axis L1. When the threaded rod rotates around the longitudinal axis L1, the moving part 32 screwed to the threaded rod moves in a direction of being drawn into the base part 30 (or a direction protruding from the base part 30). Thus, the first bar member 3 expands and contracts.

(Second wire gripper 4)
The second electric wire gripper 4 includes a first gripping piece 41 and a second gripping piece 42, and the first gripping piece 41 and the second gripping piece 42 sandwich the second portion of the electric wire W.

  In the examples shown in FIGS. 9 and 10, the first stopper 71 is provided on the second bar member 5 (fixed to the second bar member 5). In the example shown in FIGS. 9 and 10, when the first rod member 3 contracts and the moving part 32 of the first rod member 3 moves in the X direction, the first connecting member 60 provided on the moving part 32 is moved. It contacts the first stopper 71.

  When the moving portion 32 further moves in the X direction after the first connecting member 60 contacts the first stopper 71, the second bar member 5 moves together with the moving portion 32 of the first bar member 3. That is, the first stopper 71 limits the relative movement of the moving portion 32 of the first bar member 3 with respect to the second bar member 5. In the example shown in FIGS. 9 and 10, the state in which the first connecting member 60 and the first stopper 71 are in contact with each other is such that the relative movement of the first bar member 3 (moving portion 32) with respect to the second bar member 5.

The restricted state may be realized by the contact between the (members other than the first connecting member 60) and the first stopper 71 fixed to the second rod member 5.

  When the first rod member 3 contracts in the restricted state (the state in which the first connecting member 60 is in contact with the first stopper 71), the distance between the first electric wire gripping tool 2 and the second electric wire gripping tool 4 is reduced. Be shorter. Therefore, the electric wire W located between the first electric wire gripper 2 and the second electric wire gripper 4 can be bent.

(First wire support 80)
The first wire support 80 moves together with the moving portion 32 of the first rod member 3. In the example illustrated in FIG. 9, the first wire support 80 is supported by the moving unit 32 via the first connector 60. In other words, the first wire support 80 is provided on the first connector 60. The first wire support 80 is capable of supporting (fixing) the first cut end Wa of the wire W.

  When the first rod member 3 contracts in an unrestricted state (a state in which the first coupling member 60 is not in contact with the first stopper 71), the first cut end of the electric wire W supported by the first electric wire support member 80. The distance between Wa and the second cut end Wb increases. Thus, the first cut end Wa and the second cut end Wb are suitably separated.

  The second connector 62 may be configured to be able to abut on the first stopper 71 and / or a second stopper 72 described below. In this case, the second connecting member 62 functions as a member that defines a moving range of the second bar member 5 with respect to the base portion 30 of the first bar member.

  When the electric wire operating tool 1B includes the first connecting tool 60 and the second connecting tool 62, the first stopper 71 may be disposed between the first connecting tool 60 and the second connecting tool 62. preferable. In this case, when the first rod member 3 is contracted, (A) the moving portion 32 of the first rod member 3 moves to the second rod member 5 until the first connecting member 60 comes into contact with the first stopper 71. (B) After the first connecting member 60 and the first stopper 71 come into contact with each other, the moving portion 32 of the first rod member 3 moves together with the second rod member 5, (B). C) When the first stopper 71 and the second connector 62 come into contact with each other, the movement of the moving portion 32 of the first rod member 3 and the movement of the second rod member 5 (movement with respect to the base 30) stops.

(Second stopper 72)
The electric wire operating tool 1 </ b> B may include the second stopper 72. The second stopper 72 is a member that limits the relative movement of the second bar member 5 with respect to the base portion 30 of the first bar member 3.

  In the example shown in FIGS. 9 and 10, the second stopper 72 is provided at the distal end of the second rod member 5 (fixed to the distal end of the second rod member 5). In other words, the second stopper 72 is arranged at a position closer to the tip of the second rod member 5 than the first stopper 71 is.

  The second stopper 72 functions as a retaining member for preventing a connecting tool such as the second connecting tool 62 from falling off the second rod member 5. In the examples shown in FIGS. 9 and 10, the second stopper 72 functions as a member that defines the maximum value of the distance between the first wire gripper 2 and the second wire gripper 4. The state in which the second coupling tool 62 is in contact with the second stopper 72 corresponds to the maximum value of the distance between the first wire gripping tool 2 and the second wire gripping tool 4.

(Second wire support 82)
The electric wire operating tool 1B may include a second electric wire support 82. In the example shown in FIGS. 9 and 10, the second electric wire support 82 is supported (that is, fixed) by the second rod member 5. The second electric wire support 82 can support the electric wire W.

  The position of the second electric wire support 82 may be changeable along the longitudinal direction of the second rod member 5. In this case, the second electric wire support 82 has a through hole for slidably receiving the second rod member 5 and a fastening member (a fixing screw or the like) for fixing the second electric wire support 82 to the second rod member 5. And

  When the electric wire operating tool 1B includes the second electric wire support 82, the second cut end Wb of the electric wire W is suitably positioned by the second electric wire support 82 after cutting the electric wire W.

The electric wire operating tool 1B may include a third electric wire support 84. In the example shown in FIGS. 9 and 10, the third wire support 84 is supported (that is, fixed) by the second connector 62. Alternatively, the third wire support 84 may be directly supported (that is, fixed) on the base 30 of the first rod member 3. The third electric wire support 84 can support the electric wire W.

  When the electric wire operating tool 1 </ b> B includes the third electric wire support 84, the first cut end Wa of the electric wire W is appropriately positioned by the third electric wire support 84 after cutting the electric wire W. Further, after cutting the wire W, the sag (bending) of the first wire W1 is suppressed.

(First rod 51 and second rod 52)
The second rod member 5 may include a first rod 51 and a second rod 52 arranged parallel to the first rod 51. When the second rod member 5 includes the first rod 51 and the second rod 52, the bending rigidity of the second rod member 5 is improved.

  In the example shown in FIGS. 9 and 10, the first rod member 3 is arranged between the first rod 51 and the second rod 52. In this case, the moving portion 32 of the first rod member 3 preferably slides and moves in a region between the first rod 51 and the second rod 52.

  In the example shown in FIGS. 9 and 10, the first rod 51 and the second rod 52 and the moving part 32 of the first rod member 3 are connected by the first connecting member 60 so as to be relatively movable (slidable). Have been. The first rod 51 and the second rod 52 and the base 30 of the first rod member 3 are connected by a second connecting member 62 so as to be relatively movable (slidable).

  In the example shown in FIGS. 9 and 10, the first stopper 71 is disposed on each of the first rod 51 and the second rod 52. Alternatively, the first stopper 71 may be arranged on only one of the first rod 51 and the second rod 52. In the example shown in FIGS. 9 and 10, the second stopper 72 is disposed on each of the first rod 51 and the second rod 52. Alternatively, the second stopper 72 may be disposed on only one of the first rod 51 and the second rod 52.

  9 and 10, the second rod member 5 includes two rods, but the number of rods included in the second rod member 5 is one or three or more. You may.

(Structure of wire support)
An example of the structure of the first wire support 80 will be described with reference to FIG. The first electric wire support 80 includes a first gripping piece 801, a second gripping piece 802, and a support operating unit 805 for bringing the second gripping piece 802 closer to (or apart from) the first gripping piece 801. In the example illustrated in FIG. 11, by rotating the support operation unit 805 in the first rotation direction, the second gripping piece 802 moves in the direction approaching the first gripping piece 801, and the support operation unit 805 is moved to the second rotation direction. By rotating in the rotation direction, the second gripping piece 802 moves in a direction away from the first gripping piece 801.

  Therefore, when the support operation unit 805 is rotated in the first rotation direction in a state where the electric wire W is disposed between the first gripping piece 801 and the second gripping piece 802, the electric wire W is moved to the first wire support 80. Can be supported. In addition, if the support operation unit 805 is rotated in the second rotation direction, the electric wire W can be released from the first electric wire support 80.

  The second wire support 82 may have the same structure as the first wire support 80 or may have a different structure from the first wire support 80. The second electric wire support 82 may be an electric wire support that supports the electric wire by sandwiching the electric wire W. Alternatively, the second wire support 82 may be a wire support that includes a C-shaped member and an opening / closing member and positions the wire W in a space defined by the C-shaped member and the opening / closing member. Good.

  The third wire support 84 may have the same structure as the first wire support 80 or may have a different structure from the first wire support 80. The third wire support 84 may be a wire support that supports the wire by holding the wire W. Alternatively, the third wire support 84 may be a wire support that includes a C-shaped member and an opening / closing member and positions the wire W in a space defined by the C-shaped member and the opening / closing member. Good.

(Electric wire cutting method)
With reference to FIGS. 12 to 16, an electric wire cutting method according to the second embodiment will be described. FIG. 12 is a flowchart illustrating an example of the electric wire cutting method according to the second embodiment. FIGS. 13 to 16 are schematic side views schematically showing one step of the electric wire cutting method in the second embodiment.

  In the first step ST101, the first wire gripper 2 is attached to the wire W. In the second step ST102, the second electric wire gripper 4 is attached to the electric wire W. Note that the second step ST102 may be executed after the first step ST101, or may be executed before the second step ST102.

  In the third step ST103, the electric wire W is supported (fixed) by the second electric wire support 82. When the electric wire operating tool 1B does not include the second electric wire support 82, the third step ST103 is omitted.

  In the fourth step ST104, the wire W is supported (fixed) by the third wire support 84. If the electric wire operation tool 1B does not include the third electric wire support 84, the fourth step ST104 is omitted.

  FIG. 13 shows the state of the electric wire operating tool 1B after executing the first step ST101 to the fourth step ST104. In addition, in the state after the execution of the first step ST101 to the fourth step ST104, the electric wire W is not fixed to the first electric wire support 80.

  The third step ST103 and the fourth step ST104 may be executed before the first step ST101 and the second step ST102, or may be executed after the first step ST101 and the second step ST102.

  In the fifth step ST105, the wire W is bent by reducing the distance between the first wire gripper 2 and the second wire gripper 4 (see FIG. 14). In the example illustrated in FIG. 14, the wire W is bent by reducing the distance between the second wire support 82 and the third wire support 84.

  The fifth step ST105 can be executed by operating the operation unit 300 to contract the first rod member 3. The state in which the first coupler 60 is in contact with the first stopper 71 corresponds to a restricted state in which the relative movement of the moving portion 32 of the first rod member 3 with respect to the second rod member 5 is restricted. When the fifth step ST105 is performed in a state where the first coupling tool 60 is in contact with the first stopper (that is, in the restricted state), the second bar member 5 moves together with the moving part 32 of the first bar member 3. Move in X direction. Thus, the distance between the first wire gripper 2 and the second wire gripper 4 is reduced.

  During the execution of the fifth step ST105, when the first stopper 71 comes into contact with the second connecting member 62, the moving part 32 of the second rod member 5 and the first rod member 3 moves with respect to the base part 30 of the first rod member 3. Stop moving.

  In the sixth step ST106, a position between the first electric wire gripper 2 and the second electric wire gripper 4, more specifically, a position between the second electric wire holder 82 and the third electric wire holder 84 ( For example, at a position indicated by an arrow A in FIG. 14), the electric wire W is cut. By cutting the electric wire W, a first cut end Wa and a second cut end Wb are formed on the electric wire W (see FIG. 15).

  In the seventh step ST107, the first electric wire support 80 is made to approach the first cut end Wa. The seventh step ST7 is executed by operating the operation unit 300 to extend the first rod member 3.

  When the first rod member 3 is extended by operating the operation unit 300, the moving unit 32 of the first rod member 3 moves in the −X direction with respect to the base unit 30. A tension acts on the first rod member 3 and the second rod member 5 by the electric wire W gripped by the first wire gripper 2 and the second wire gripper 4. Therefore, when the moving section 32 moves in the −X direction, the second bar member 5 also moves in the −X direction following the movement of the moving section 32.

  In the seventh step ST107, when the first rod member 3 is further extended, the second connecting member 62 and the second stopper 72 come into contact with each other (see FIG. 15). When the second connecting member 62 and the second stopper 72 come into contact with each other, the second bar member 5 cannot move in the −X direction with respect to the base portion 30. For this reason, the moving part 32 of the first rod member 3 moves in the −X direction independently of the second rod member 5, and the first connecting member 60 connected to the moving part 32 and the second rod member 5 The first stopper 71 is separated from the first stopper 71 (see FIG. 15).

  In the eighth step ST108, the first cut end Wa is fixed to the first electric wire support 80. The fixing is performed, for example, by clamping the first cut end Wa between the first gripping piece 801 of the first wire support 80 and the second gripping piece 802 of the first wire support 80. By performing the seventh step ST107, the first wire support 80 is close to the first cut end Wa, so that the step of fixing the first cut end Wa to the first wire support 80 is easy. It is executable.

  After the first cut end Wa is fixed to the first wire support 80, it is preferable that the support of the wire W by the third wire support 84 is released.

  In the ninth step ST109, the first cut end Wa and the second cut end Wb are separated from each other by moving the moving portion 32 of the first bar member 3 relative to the second bar member 5 ( See FIG. 16). Thus, the distance between the first cut end Wa and the second cut end Wb increases, and the first cut end Wa and the second cut end Wb are separated.

  The ninth step ST109 can be executed by operating the operation unit 300 to contract the first rod member 3. The contraction of the first rod member 3 is executed in an allowable state in which the relative movement of the moving portion 32 of the first rod member 3 with respect to the second rod member 5 is allowed. That is, the contraction of the first rod member 3 in the ninth step ST109 is performed in a state where the first stopper 71 is separated from the first connecting member 60. The ninth step ST109 can be executed by moving the moving portion 32 relative to the second rod member 5 without changing the distance between the first wire gripper 2 and the second wire gripper 4. is there.

  In the second embodiment, the electric wire is bent by contracting the first rod member 3 (fifth step ST105), and the first cut end Wa and the second cut end are contracted by contracting the first rod member 3. The distance from Wb is increased (ninth step ST109). That is, the operation of bending the electric wire W and the operation of increasing the distance between the first cut end Wa and the second cut end Wb can be performed simply by contracting the first rod member 3. it can.

  Furthermore, in the second embodiment, when the first stopper 71 and the first connecting member 60 are in contact with each other, the relative movement of the moving portion 32 of the first rod member 3 with respect to the second rod member 5 is restricted. The restricted state, in which the first stopper 71 and the first connecting member 60 are separated from each other, is an allowable state in which the relative movement of the moving portion 32 of the first rod member 3 with respect to the second rod member 5 is permitted. . Therefore, unlike the first embodiment, there is no need to operate the operation unit 70A to switch from the restricted state to the permitted state or to switch from the permitted state to the restricted state. In other words, only the operation of the operation unit 300 can perform all the expansion and contraction operations of the first bar member 3 and the relative movement between the first bar member 3 and the second bar member 5.

  As described above, in the electric wire cutting method according to the second embodiment, the work burden on the worker is further reduced as compared with the first embodiment, and the worker can safely and efficiently cut the electric wire. Can be implemented.

  The electric wire operating tool 1B according to the second embodiment may be used to execute the electric wire cutting method described above. That is, the worker can safely and efficiently perform the wire cutting operation using the wire operating tool 1B according to the second embodiment.

(Wire connection method)
The electric wire connection method in the second embodiment will be described with reference to FIGS. FIG. 12 is a flowchart illustrating an example of an electric wire connection method according to the second embodiment. FIG. 17 is a schematic side view schematically showing one step of the electric wire connection method in the second embodiment.

  Before the execution of the electric wire connection method, the insulation coating is removed at the first end (first cut end Wa) of the first electric wire W1 and the second end (second cut end Wb) of the second electric wire W2. It is assumed that the core of the electric wire is exposed at the first end (Wa) and the second end (Wb).

  In the tenth step ST110, the second end (Wb) of the second electric wire W2 gripped by the second electric wire gripper 4 is inserted into the second end Sb of the connection sleeve SV (see FIG. 17). The tenth step ST110 is executed, for example, after the ninth step ST109 of the above-described electric wire cutting method.

  In the eleventh step ST111, by moving the moving portion 32 of the first rod member 3 relative to the second rod member 5, the first end portion of the first electric wire W1 fixed to the first electric wire support member 80 ( Wa) is inserted into the first end Sa of the connection sleeve SV. Thus, the first end (Wa) of the first electric wire W1 and the second end (Wb) of the second electric wire W2 are connected via the connection sleeve SV. After the eleventh step ST111, even if the connection sleeve SV is crimped, the connection sleeve SV and the first end (Wa) are crimped, and the connection sleeve SV and the second end (Wb) are crimped. Good.

  The eleventh step ST111 can be executed by operating the operation unit 300 to extend the first rod member 3. The extension of the first rod member 3 is executed in a state where the first stopper 71 and the first connecting member 60 are separated (permissible state). The eleventh step ST111 can be executed by moving the moving portion 32 relative to the second rod member 5 without changing the distance between the first wire gripper 2 and the second wire gripper 4. is there.

  In the second embodiment, the first end (Wa) of the first electric wire W1 can be inserted into the connection sleeve SV only by extending the first rod member 3. Therefore, the work load when inserting the first end (Wa) into the connection sleeve SV is greatly reduced. Further, when inserting the first end portion (Wa) into the connection sleeve SV, the operator is not required to have an unreasonable posture or difficult movement. Furthermore, since the amount of bending below the electric wire W during operation can be reduced, the risk of the electric wire during operation interfering with other electric wires is reduced. For this reason, the worker can safely and efficiently perform the wire connection work.

  The electric wire operating tool 1B according to the second embodiment may be used to execute the electric wire connection method described above. That is, the worker can safely and efficiently perform the connection work of the electric wires using the electric wire operation tool 1B according to the second embodiment.

(Third embodiment)
The electric wire operating tool 1C according to the third embodiment will be described with reference to FIG. FIG. 18 is a schematic side view of an electric wire operating tool 1C according to the third embodiment.

  The electric wire operating tool 1C according to the third embodiment and the electric wire operating tool according to the first embodiment (or the second embodiment) include a structure of a first rod member, a structure of a second rod member, and a first rod member. The arrangement relationship with the second rod member, the structure of the first connector, the structure of the second connector, the arrangement of the movement restricting member, and the structure of the first wire support differ. For this reason, in the third embodiment, the structure of the first bar member 3, the structure of the second bar member 5, the arrangement relationship between the first bar member 3 and the second bar member 5, the structure of the first coupling member 60 '. The structure of the second connector 62 ', the arrangement of the movement restricting member 7, and the first wire support 80' will be mainly described, and the repeated description of the other components will be omitted.

  The first rod member 3 includes a base part 30 and a moving part 32. The first rod member 3 can be expanded and contracted when the moving section 32 moves relative to the base section 30. The first bar member 3 includes a connection mechanism (gear mechanism, screw mechanism, etc.) for connecting the base portion 30 and the moving portion 32 so as to be relatively movable. It expands and contracts by operating the unit 300. The operation of the operation unit 300 is performed using, for example, a remote control tool. Note that the mechanism for extending and contracting the extendable first rod member 3 using the remote control tool may be the same as the mechanism for extending and contracting the first rod member 3 in the second embodiment.

  In the example shown in FIG. 18, a first wire support 80 ′ is attached to the moving portion 32 of the first rod member 3 so as to be position-adjustable along the longitudinal direction of the first rod member 3. In the example illustrated in FIG. 18, the first wire support 80 ′ can be fixed to the moving unit 32 by operating the second operation unit 310 with the remote control tool. It is possible to release the fixing of the moving part 80 'to the moving part 32. When the first rod member 3 is expanded and contracted in a state where the first wire support 80 ′ is fixed to the moving unit 32, the first wire support 80 ′ moves integrally with the moving unit 32. On the other hand, in a state where the fixing of the first electric wire support 80 ′ is released, the first electric wire support 80 ′ can be slid with respect to the moving portion 32 using a remote control tool.

  In the example shown in FIG. 18, the position of the first wire support 80 ′ is freely adjustable with respect to the first rod member 3, but the first wire support 80 ′ is movable with respect to the first rod member 3. The position may not be adjustable. In this case, the second operation unit 310 can be omitted.

  In the example shown in FIG. 18, the first connecting member 60 'connects the first bar member 3 and the second bar member 5 so as to be relatively movable. In the example shown in FIG. 18, the first wire support 80 'also serves as the first connector 60'. The first connector 60 ′ (first wire support 80 ′) can be fixed to the moving part 32 of the first rod member 3. The first connecting member 60 ′ is slidable with respect to the second rod member 5.

  In the example shown in FIG. 18, the first connector 60 ′ and the first wire support 80 ′ are one member integrally formed, but alternatively, the first connector 60 ′ and the first wire It is separate from the wire support 80 'and may be fixed to each other. Alternatively, the first connector 60 ′ and the first wire support 80 ′ may be separately attached to the moving unit 32.

  In the example illustrated in FIG. 18, the first rod member 3 (more specifically, the base portion 30) is indirectly attached to the first wire gripping tool 2 via the second connector 62 '. . In this respect, the third embodiment is different from the first and second embodiments in which the first rod member 3 is directly attached to the first electric wire gripping tool 2. However, also in the third embodiment, the first rod member 3 may be directly attached to the first electric wire holder 2. That is, in the example illustrated in FIG. 18, the second connecting tool 62 ′ is connected to the first wire gripping tool 2 via the first connecting portion 24, but the first rod member 3 (more specifically, , Base portion 30) may be connected to the first wire gripper 2 via the first connection portion. The connection between the second connector 62 '(or the base portion 30) and the first wire gripper 2 may be a swingable connection or a non-swingable connection.

  The second connecting member 62 'connects the first bar member 3 and the second bar member 5 so as to be relatively movable. In the example shown in FIG. 18, the second connecting member 62 ′ is attached to the first rod member 3, and the second connecting member 62 ′ and the second rod member 5 are relatively movable.

  In the example shown in FIG. 18, the second coupling tool 62 ′ includes a receiving portion 600 that can receive the end 58 of the second rod member 5. Further, the end 58 of the second bar member 5 is movable within the space SP defined by the receiving portion 600. More specifically, the end 58 of the second bar member 5 is It is movable between a first contact position that contacts the first end 601 and a second contact position that contacts the second end 602 of the receiving part 600. The shape of the receiving portion 600 may be substantially a closed shell shape, a rectangular frame shape with an open side surface, or a U-shape.

  In the example shown in FIG. 18, since the second rod member 5 and the second connecting member 62 'are arranged along the X direction, the receiving portion 600 is provided on the second connecting member 62'. I have. However, when the second bar member 5 and the second connecting member 62 'are eccentrically arranged, in other words, when the movement of the second bar member 5 does not interfere with the second connecting member 62', the receiving member is not received. The unit 600 may be omitted.

  In the example illustrated in FIG. 18, the movement restricting member 7 is provided on the second rod member 5. The movement restricting member 7 is a first stopper 71 ′ that restricts the relative movement of the first rod member 3 with respect to the second rod member 5. More specifically, when the first rod member 3 contracts and the moving portion 32 moves in the X direction, the first connecting member 60 '(first wire support member 80') also moves in the X direction. When the first rod member 3 further contracts after the first connecting member 60 '(the first wire support member 80') abuts on the first stopper 71 ', the second rod member 5 becomes the first rod member. 3 moves in the X direction together with the moving section 32. That is, the relative movement of the first bar member 3 (more specifically, the moving unit 32) with respect to the second bar member 5 is restricted. The first connector 60 ′ (first wire support 80 ′) can contact the movement restricting member 7 (more specifically, the first stopper 71 ′) and can be separated from the movement restricting member 7. is there.

  In the example illustrated in FIG. 18, the first stopper 71 ′ is a protrusion provided on the second rod member 5 (more specifically, a protrusion protruding in a direction perpendicular to the X direction). The first stopper 71 'is disposed between the first connector 60' and the second connector 62 '.

  In the example shown in FIG. 18, the second wire gripper 4 is attached to one end of the second rod member 5. The other end 58 of the second rod member 5 functions as a retaining portion 5a for preventing the second rod member 5 from falling out of the second connector 62 '.

(Electric wire cutting method)
The electric wire cutting method according to the third embodiment will be described with reference to FIGS. FIG. 19 is a flowchart illustrating an example of the electric wire cutting method according to the third embodiment. FIGS. 18, 20 to 23 are views schematically showing one step of the electric wire cutting method in the third embodiment.

  The first step ST201 and the second step ST202 are respectively the same as the first step ST101 and the second step ST102 in the second embodiment. For this reason, a repeated description is omitted. FIG. 18 shows a state of the electric wire operating tool 1C after performing the first step ST201 and the second step ST202. When the electric wire operating tool 1C according to the third embodiment includes the second electric wire support 82, a step of supporting the electric wire W on the second electric wire support 82 (the electric wire W is attached to the second electric wire support 82). Fixing step) may be performed. This step may be executed before the first step ST201 and the second step ST202, or may be executed after.

  In the third step ST203, the wire W is bent by reducing the distance between the first wire gripper 2 and the second wire gripper 4 (see FIG. 20). The third step ST3 can be executed by operating the operation unit 300 to contract the first rod member 3. When the first rod member 3 is contracted, the first connector 60 '(first wire support 80') comes into contact with the first stopper 71 '. Thereafter, when the first bar member 3 further contracts, the second bar member 5 moves in the X direction together with the moving portion 32 of the first bar member 3. Thus, the distance between the first wire gripper 2 and the second wire gripper 4 is reduced.

  In the fourth step ST204, the electric wire W is cut at a position between the first electric wire gripping tool 2 and the second electric wire gripping tool 4 (for example, a position indicated by an arrow A in FIG. 20). By cutting the wire W, a first cut end and a second cut end are formed on the wire W.

  In the fifth step ST205, the first wire support 80 'is moved closer to the first cut end Wa (see FIG. 21). The fifth step ST205 is executed by operating the operation unit 300 to extend the first bar member 3.

  When the first rod member 3 is extended by operating the operation unit 300, the moving unit 32 of the first rod member 3 moves in the −X direction with respect to the base unit 30. A tension acts on the first rod member 3 and the second rod member 5 by the electric wire W gripped by the first wire gripper 2 and the second wire gripper 4. Therefore, when the moving section 32 moves in the −X direction, the second bar member 5 also moves in the −X direction following the movement of the moving section 32.

  The extension of the first rod member 3 is preferably performed until the contact between the first connector 60 '(first wire support 80') and the first stopper 71 'is released. In the example illustrated in FIG. 21, when the first rod member 3 is extended, the retaining portion 5a of the second rod member 5 comes into contact with the second connector 62 ′ (more specifically, the first end 601). Done until.

  In the sixth step ST206, the first cut end Wa is fixed to the first wire support 80 '. The fixing is performed, for example, by clamping the first cut end Wa between the first gripping piece 801 of the first wire support 80 'and the second gripping piece 802 of the first wire support 80'. (See FIG. 22).

  The sixth step ST206 may be executed after the first wire support 80 'is slid in the -X direction with respect to the moving part 32 of the first rod member 3. The slide movement is performed by operating the second operation unit 310 to release the fixing between the moving unit 32 and the first wire support 80 ′, and then slide the first wire support 80 ′ in the −X direction. It may be executed by moving. The operation of the second operation unit 310 and the sliding movement of the first electric wire support 80 'are executed using a remote control tool. After the sliding movement, by operating the second operation part 310, the first wire support 80 'is fixed to the moving part 32 again. In addition, depending on the arrangement of the first electric wire support 80 ′ with respect to the moving portion 32 of the first rod member 3 and / or the arrangement of the first stopper 71 ′ of the second rod member 5, the movement of the first electric wire support 80 ′. The slide moving step for the part 32 may be omitted.

  In the seventh step ST207, the first cut end Wa and the second cut end Wb are separated from each other by moving the moving portion 32 of the first bar member 3 relatively to the second bar member 5 ( See FIG. 23). Thus, the distance between the first cut end Wa and the second cut end Wb increases, and the first cut end Wa and the second cut end Wb are separated.

  The seventh step ST207 can be executed by operating the operation unit 300 to contract the first rod member 3. The contraction of the first rod member 3 is executed in an allowable state in which the relative movement of the moving portion 32 of the first rod member 3 with respect to the second rod member 5 is allowed. That is, the contraction of the first rod member 3 in the seventh step ST207 is executed in a state where the first stopper 71 'is separated from the first connecting member 60' (the first wire supporting member 80 '). The seventh step ST207 can be executed by moving the moving portion 32 relative to the second rod member 5 without changing the distance between the first wire gripper 2 and the second wire gripper 4. is there. In the seventh step ST207, the state in which the retaining portion 5a is in contact with the second connector 62 '(more specifically, the first end 601) is maintained.

  The electric wire operating tool 1C according to the third embodiment may be used to execute the electric wire cutting method described above.
