Description

Field of technology to which the invention relates

The present invention relates to a wire cutting tool, a wire cutting tool component, a wire cutting and separating method, and a wire joining method.

State of the art

Methods for cutting and separating electrical wire are known. Electrical wire cutting and splitting methods use tools to cut and split electrical wire. An electrical wire cutting and separating tool comprises a first electrical wire gripping tool, a second electrical wire gripping tool and a telescopic rod located between the first electrical wire gripping tool and the second electrical wire gripping tool. When the electric wire is cut and separated by the electric wire cutting and dividing tool, first of all, the first electric wire gripping tool grips the first electric wire portion, and the second electric wire gripping tool grips the second electric wire portion. The telescopic rod is then shortened so that the distance between the first electrical wire gripping tool and the second electrical wire gripping tool is reduced. As a result of the shortening, the electric wire located between the first electric wire gripping tool and the second electric wire gripping tool is weakened. The electrical wire is then cut at a location between the first electrical wire gripping tool and the second electrical wire gripping tool (at the location where the electrical wire is loosened). Then, the electric wire support tool that supports one of the cut ends of the electric wire is rotated 180 degrees around the telescopic rod to vertically separate one cut end of the electric wire and the other cut end of the electric wire from each other.

When one cut end of the electric wire and the other cut end of the electric wire are connected again after finishing the work on the electric wire, first of all, the electric wire support tool that supports one of the cut ends of the electric wire is rotated 180 degrees around the telescopic rod to align the position of one the cut end of the electrical wire with the position of the other cut end of the electrical wire. The first end of the coupling sleeve is then attached to one cut end of the electrical wire. The other cut end of the electrical wire is then inserted into the second end of the coupling sleeve, with the position of the second end of the coupling sleeve being aligned with the other cut end of the electrical wire. The coupling sleeve is then compressed and deformed to jointly compress the coupling sleeve, one cut end of the electrical wire, and the other cut end of the electrical wire.

As for the current art, Patent Literature 1 describes a tool for facilitating the production of a trolley wire. A tool for facilitating the production of a contact wire and described in Patent Literature 1 includes a pair of wire clamps configured to clamp an electrical wire in a sheath, a telescopic device configured to bend a portion of an electrical wire in the sheath between the wire clamps, and a pair of clamping devices configured with the ability to clamp sections in the sheath near both ends at the cutting points of the cut electrical wire in the sheath between the wire clamps. In addition, at least one of the pair of clamping devices is configured to move in the longitudinal direction of the telescopic device. In the tool facilitating the production of a contact wire and described in Patent Literature 1, since one of a pair of clamping devices moves in the longitudinal direction of the telescopic device when the connecting sleeve is crimped together with the core wire, bending of the connecting portion of the core wires is prevented.

It should be noted that in this description, elements having the same type of function are designated by the same or similar reference numbers. In addition, repeated descriptions of elements designated by the same or similar reference numerals may be omitted. Moreover, in this specification, “wire (wire material)” is, for example, “electrical wire.” When the "wire" is an "electrical wire", the "wire working tool", the "first wire gripping tool", the "second wire gripping tool" and the "wire supporting tool" such as the first wire supporting tool, herein in the description mean “electrical wire working tool”, “first electric wire gripping tool”, “second electric wire gripping tool” and “electrical wire supporting tool” such as the first electric wire supporting tool, respectively. "Wire (wire material)" in this description may be a high voltage line.

Determining directions

In this description, the direction along the longitudinal axis AX of the first rod member 3 from the movable portion 32 of the first rod member 3 to the main portion 30 of the first rod member 3 is called the “first direction,” and the direction opposite to the “first direction” is called the “second direction.”

First embodiment of the invention

The wire working tool 1A according to the first embodiment of the invention will be described with reference to FIG. 1 and 2. In FIG. 1 and 2 are schematic side views of a wire working tool 1A according to the first embodiment of the invention.

The wire working tool 1A includes a first wire gripping tool 2, a second wire gripping tool 4, a second rod member 5 connected to the second wire gripping tool 4, a connecting member 6 that connects the first rod member 3 and the second rod member 5 to releasably, and a support member 7. The wire working tool 1A may include a fastening tool 8 that secures the wire W or the connecting sleeve SV described below.

The first wire gripping tool 2 grips the first wire portion W. The first wire gripping tool 2 has, for example, a first gripping member 21 and a second gripping member 22, and clamps the first wire portion W with the first gripping member 21 and the second gripping member 22. for capture.

The first rod element 3 is connected to the first tool 2 for gripping the wire. The connection between the first rod member 3 and the first wire gripping tool 2 may be a connection that is rotatable about an axis perpendicular to the first direction DR1, or may be a connection that is not rotatable. In addition, the first rod member 3 may be detachable from the first wire gripping tool 2 (in other words, the first wire gripping tool 2 and the first rod member 3 may be separate members, wherein the first wire gripping tool 2 may be attached to the first rod element 3). Although in the example shown in FIG. 1(a), the first rod member 3 is connected to the first wire gripping tool 2 directly, the first rod member 3 may be connected to the first wire gripping tool 2 indirectly.

The first rod member 3 includes a main portion 30 and a movable portion 32. The first rod member 3 can be lengthened and shortened depending on the relative movement of the movable portion 32 relative to the main portion 30. The first rod member 3 includes a coupling mechanism (gear mechanism, screw mechanism, or the like). which connects the main section 30 and the movable section 32 with each other with the possibility of relative movement, while the first rod element 3 is lengthened or shortened under the action of the actuator 300 installed on the main section 30. The actuator 300 is driven, for example , using the remote control tool. The first rod element 3 is made, for example, of fiber-reinforced plastic (FRP). It should be appreciated that the cross-sectional shape of the first rod member (main portion 30 and movable portion 32) is not particularly limited as long as the main portion 30 and movable portion 32 can move relative to each other, and may be circular, elliptical, polygonal, hemispherical or the like, or can be chosen as needed.

The second wire gripping tool 4 grips the second wire portion W. The second wire gripping tool 4 includes, for example, a first gripping member 41 and a second gripping member 42, and clamps the second wire portion W with the first gripping member 41 and the second gripping member 42 for capture.

The second rod element 5 is connected to the second tool 4 for gripping the wire. The connection between the second rod member 5 and the second wire gripping tool 4 may be a connection that is rotatable about an axis perpendicular to the first direction DR1, or may be a connection that is not rotatable. In addition, the second rod member 5 may be detachable from the second wire gripping tool 4 (in other words, the second wire gripping tool 4 and the second rod member 5 may be separate members, and the second wire gripping tool 4 may be attached to the second rod member 5). rod element 5). The second rod element 5 is made, for example, of fiber-reinforced plastic (FRP). Although in the example shown in FIG. 1(a), the second rod member 5 is connected to the second wire gripping tool 4 directly, the second rod member 5 may be connected to the second wire gripping tool 4 indirectly.

The connecting element 6 connects the movable section 32 of the first rod element 3 and the second rod element 5 to each other in a detachable manner. In the example shown in FIG. 1(a), the tip of the movable portion 32 (end in the second direction DR2) and the tip of the second rod member 5 (end in the second direction DR1) are connected to each other by a connecting member 6.

As shown in FIG. 1(b), when the movable portion 32 moves relative to the main portion 30, and the movable portion 32 of the first rod member 3 is connected to the second rod member 5, the second rod member 5 also moves relative to the main portion 30 of the first rod member 3. On the other hand, as shown in Fig. 2 as an example, when the movable portion 32 moves relative to the main portion 30 while the movable portion 32 of the first rod member and the second rod member 5 are disconnected from each other, the movable portion 32 of the first rod member 3 moves relative to the second rod member 5.

As shown in FIG. 1(b) or 6 as an example, it is assumed that the first rod member 3 is shortened in a state where the first wire portion W is gripped by the first wire gripping tool 2 and the second wire portion W is gripped by the second wire gripping tool 4. In particular, it is assumed that the movable portion 32 of the first rod member 3 moves in the first direction DR1 (in other words, in the direction of the main portion 30) when the movable portion 32 of the first rod member 3 and the second rod member 5 are in a connected state. In this case, since the distance between the first wire gripping tool 2 and the second wire gripping tool 4 is reduced, it is possible for the wire portion W between the first wire gripping tool 2 and the second wire gripping tool 4 to be bent. As a result, it is possible to easily cut the wire portion W between the first wire gripping tool 2 and the second wire gripping tool 4 (in other words, the bent wire portion W) using the cutting tool.

On the other hand, as shown in FIG. 14 as an example, it is assumed that the first rod element 3 is shortened, whereby the first wire W1 (or the connecting sleeve SV into which the end of the first wire W1 is inserted) is attached to the fastening tool 8. In particular, it is assumed that the movable portion 32 of the first The rod member 3 moves in the first direction DR1 (in other words, in the direction of the main portion 30) when the movable portion 32 of the first rod member 3 and the second rod member 5 are in a separated state. In this case, due to the movement of the movable portion 32, the first wire W1 (or connecting sleeve) attached to the fastening tool 8 moves in a direction away from the second rod member 5. This movement facilitates at least part of the work of connecting the first cut end Wa of the first wire W1 and the second cut end Wb of the second wire W2 with each other (for example, the work of inserting the second cut end Wb into the connecting sleeve SV).

In the example shown in FIG. 2, the connecting member 6 includes a pin member 6a that connects the movable portion 32 of the first rod member 3 and the second rod member 5 to each other. The movable element 32 of the first rod element 3 has a first hole 32h into which the connecting element 6 (in particular the pin element 6a) is inserted, and the second rod element 5 has a second hole 5h into which the connecting element 6 (in particular the pin element 6a) is inserted ). Moreover, when the connecting member 6 is inserted into the first hole 32h and the second hole 5h, the movable portion 32 of the first rod member 3 and the second rod member 5 are in a connected state. On the other hand, when the connecting member 6 is removed from at least one of the first hole 32h and the second hole 5h, the movable portion 32 of the first rod member 3 and the second rod member 5 are in a separated state. At h or the second hole 5h, the movable portion 32 of the first rod element 3 and the second rod element 5 are in a separated state. In the example shown in FIG. 2, the first hole 32h is formed in the plate 320 located at the tip of the movable portion 32. In addition, the second hole 5h is formed in the plate 50 located at the tip of the second rod member 5.

It should be noted that the shape and structure of the connecting member 6 is not limited to the example shown in FIG. 2. Any shape and design of the connecting member may be used as long as it can connect and separate the movable portion 32 of the first rod member 3 and the second rod member 5. For example, the connecting member 6 may include an engaging protruding portion and an engaging recessed portion a portion (or recessed groove) that connects the movable portion 32 of the first rod member 3 and the second rod member 5 to each other.

The support member 7 withstands the tensile force acting on the first wire gripping tool 2 and the second wire gripping tool 4 when the movable portion 32 of the first rod member 3 and the second rod member 5 are in a separated state. A detailed description is given below.

The fastening tool 8 is a member that fixes the wire W (for example, the first wire W1) or the connecting sleeve SV (for example, the connecting sleeve connecting the end of the first wire W1 and the end of the second wire W2 to each other). In the example shown in FIG. 1(a), the fastening tool 8 has a first clamping element 81, a second clamping element 82 and an actuator 83 for controlling the fastening tool. In the example shown in FIG. 1(a), by operating the fastening tool control actuator 83 using remote control means or the like, the distance between the first clamping element 81 and the second clamping element 82 can be changed.

By controlling the actuator 83 for controlling the fastening tool to reduce the distance between the first clamping element 81 and the second clamping element 82, it is possible to fix the wire W (for example, the first wire W1) or the connecting sleeve SV in the fastening tool 8. In addition, by controlling The actuator 83 for controlling the fastening tool can separate the wire W (for example, the first wire W1) or the connecting sleeve SV from the fastening tool 8 in order to increase the distance between the first clamping element 81 and the second clamping element 82.

In the example shown in FIG. 1(a), the fastening tool 8 moves with the movable portion 32 of the first rod member 3. Specifically, the fastening tool 8 has a connecting portion 80, wherein the connecting portion 80 is attached to the movable portion 32 of the first rod member 3. Thus, the movement of the movable portion 32 allows the fastening tool 8 attached to the movable portion 32 to move with the movable portion 32.

Alternatively, the connecting portion 80 of the fastening tool 8 may be slidably movable relative to the movable portion 32 of the first rod member 3. In this case, the arrangement may allow the fastening tool 8 to move with the movable portion 32 of the first rod member when the pressure portion 32a located on the movable portion 32 applies pressure to the press portion 80a located on the fastening tool 8. It should be noted that when the fastening tool 8 can be slidably moved relative to the movable portion 32 of the first rod member 3, remote control means or the like may be used. to ensure movement of the fastening tool 8 relative to the movable section 32.

In the example shown in FIG. 1(a), the fastening tool 8 is located in the middle portion of the movable portion 32. Alternatively, the fastening tool 8 may be located either at the tip 32t of the movable portion 32, or can be slidably moved between the tip 32t and the support end of the movable portion 32. It is contemplated that that the rod-shaped component forming the middle portion of the movable portion 32 is made of non-metal, at least a portion of the fastening tool 8 is made of metal, wherein the tip 32t includes a metal connecting element into which the connecting element 6 is inserted. In this case, due to the location of the fastening tool 8, which is at least partially made of metal, metal elements can be assembled around the tip 32t, which is at least partially made of metal. As a result, for example, it is easier to place an insulating coating on an area where metal materials are located while work performed using a wire tool attached to the wire is suspended. It should be noted that a fastening tool 8, at least partially made of metal, may be configured to be attached to the tip 32t, or a fastening tool 8, at least partially made of metal, and a tip 32t, at least partially made of metal , can be executed as a single unit.

Optional Additional Elements

Below is a description of optional additional elements that can be used in the wire working tool 1A according to the first embodiment of the invention.

In the example shown in FIG. 1(a) and 1(b), the wire working tool 1A includes a support member 7, wherein the support member 7 has a first force transmission surface 71t. In addition, the wire working tool 1A includes a second rod member 5, wherein the second rod member 5 (specifically, the second connecting portion 51 of the second rod member 5) has a second force transmission surface 51t. The first force transmission surface 71t and the second force transmission surface 51t may come into contact with each other and may be spaced apart from each other.

In the example shown in FIG. 2, it is assumed that when the movable portion 32 of the first rod member 3 and the second rod member 5 are in a separated state, the first wire gripping tool 2 and the second wire gripping tool 4 are subjected to a tensile force F. It should be noted that the tensile force F acting on the first wire gripping tool 2 and the second wire gripping tool 4 means a force acting in the direction in which the first wire gripping tool 2 and the second wire gripping tool 4 move in a direction away from each other.

In the example shown in FIG. 2, the wire working tool 1A includes a support member 7. Thus, even when the movable portion 32 of the first rod member 3 and the second rod member 5 are in a separated state, the support member 7 can withstand the tensile force exerted on the first wire gripping tool 2 and a second tool 4 for gripping the wire. In other words, even when the movable portion 32 of the first rod member 3 and the second rod member 5 are in a separated state and the tensile force F acts on the first wire gripping tool 2 and the second wire gripping tool 4, the distance between the first wire gripping tool 2 and the second tool 4 for gripping the wire is supported by the supporting element 7.

In the example shown in FIG. 2, the first force transmission surface 71t and the second force transmission surface 51t are in contact with each other. Thus, the tensile force F acting on the second wire gripping tool 4 is transmitted to the support member 7 through the second rod member 5, the second force transmission surface 51t, and the first force transmission surface 71t. Moreover, in the example shown in FIG. 2, the support member 7 is attached to the main portion 30 of the first rod member 3. Specifically, the support member 7 is attached to the main portion 30 of the first rod member 3 by means of a connecting block 39. Thus, the tensile force F acting on the first gripping tool 2 wires, is transmitted to the supporting element 7 through the main section 30 of the first rod element 3 and the connecting block 39.

It should be noted that in the example shown in FIG. 2, the support member 7 has a first connecting portion 71 which slidably connects the supporting member 7 to the second rod member 5, wherein the first force transmission surface 71t is located on the first connecting portion 71. The first connecting portion 71 has a through hole 71h, into which the second rod element 5 is inserted with the ability to move with sliding.

Moreover, in the example shown in FIG. 2, the second rod element 5 has a second connecting portion 51 which slidably connects the second rod element to the supporting element 7, wherein the second connecting portion 51 has a second force transmission surface 51t. The second connecting section 51 has a through hole 51h into which a rod-shaped section 70 of the supporting element 7 is slidably inserted. In this case, the first connecting portion 71, the second connecting portion 51, the second rod member 5 and the rod-shaped portion 70 prevent the second rod member 5 from rotating about the longitudinal axis of the second rod member 5. Thus, the second rod member 5 does not rotate unintentionally, and the action for changing the state of the movable portion 32 of the first rod member 3 and the second rod member 5 from a separated state to a connected state (or an action to change the state from a connected state to a separated state) is not prevented by rotating the second rod member 5.

In the example shown in FIG. 2, the wire working tool 1A has a first connecting portion 71 and a second connecting portion 51. Thus, the sliding relative movement between the support member 7 and the second rod member 5 is carried out in an unimpeded manner. It should be noted that from the point of view of the relative sliding movement between the support member 7 and the second rod member 5, it is preferable that the longitudinal axis of the second rod member 5 and the longitudinal axis of the rod-shaped portion 70 of the support member 7 be parallel to each other.

In the example shown in FIG. 1(a), the wire working tool 1A may have a wire support tool 9 that supports the wire W. In the example shown in FIG. 1(a), the wire support tool 9 is attached to the first rod member 3 (specifically, to the main portion 30 of the first rod member 3). The wire support tool 9 may support the wire W (or the first wire W1 described below, which is formed by cutting the wire W).

When the wire working tool 1A includes the wire support tool 9, the wire W (or the first wire W1 described below, which is formed by cutting the wire W) is positioned properly by the wire support tool 9. In addition, the wire W (or the first wire W1) is prevented from becoming loose (bent).

As shown in FIG. 3(a) and 3(b), the wire working tool 1A may include a limit member 100 that changes the maximum separation distance L between the first wire gripping tool 2 and the second wire gripping tool 4. When the wire tool 1A includes the restriction member 100, the wire tool 1A can be connected to the wire W in a state in which the maximum separation distance L is small (see FIG. 3(a)), wherein the wire tool 1A can be disconnected from the wire W in a state in which the maximum separation distance L is large (see Fig. 3(b)); in other words, the tensile force acting on the wire working tool 1A is small. In this case, the work of separating the wire working tool 1A from the wire W is made easier.

It should be noted that in the example shown in FIG. 3(a), the restriction member 100 is located between the first force transmission surface 71t and the second force transmission surface 51t. In addition, the maximum separation distance L when the restriction element 100 is located between the first force transmission surface 71t and the second force transmission surface 51t is equal to the distance L1, and the maximum separation distance L when the restriction element 100 is not located between the first force transmission surface 71t and the second force transmission surface 51t is equal to the distance L2. Distance L1 is less than distance L2.

It should be noted that the shape and structure of the restriction member 100 is not limited to the example shown in FIG. 3(a) and 3(b). As the shape and structure of the limiting member 100, any shape and structure may be used, provided that the maximum separation distance L between the first wire gripping tool 2 and the second wire gripping tool 4 can be varied. For example, the limiting member 100 may be a pin member that may protrude from the outer peripheral surface of the rod-shaped portion 70 of the support member 7. In this case, the maximum separation distance L when the pin member protrudes from the outer peripheral surface of the rod-shaped portion 70 is equal to the distance L1, and the maximum the separation distance L when the pin member does not protrude from the outer peripheral surface of the rod-shaped portion 70 is equal to the distance L2.

Method of cutting and separating wire

A wire cutting and dividing method according to the first embodiment of the invention will be described with reference to FIG. 4–10. In fig. 4 is a flowchart illustrating an example of a wire cutting and dividing method according to the first embodiment of the invention. In fig. 5 to 10 show schematically the steps of a wire cutting and dividing method according to the first embodiment of the invention.

The wire cutting and dividing method according to the first embodiment of the invention is carried out using a wire working tool 1. The wire working tool 1 used in the wire cutting and dividing method according to the first embodiment of the invention may be the wire working tool 1A according to the first embodiment or another wire working tool.

The wire working tool 1 used in the wire cutting and separating method according to the first embodiment of the invention includes a first wire gripping tool 2, a first rod member 3 that is connected to the first wire gripping tool 2 and can be extended or shortened depending on the movement. a movable portion 32 relative to the main portion 30, a second wire gripping tool 4, a second rod member 5 connected to the second wire gripping tool 4, and a connecting member 6 that releasably connects the first rod member 3 and the second rod member 5. The wire working tool 1 may comprise at least one support element 7, a fastening tool 8 that secures the wire, for example wire W1 (or a connecting sleeve SV into which the end of the wire, for example the first wire W1, is inserted), and a wire support tool 9 , which supports the W wire.

In the first step ST1, the first wire gripping tool 2 is attached to the wire W. In the second step ST2, the second wire gripping tool 4 is attached to the wire W. It should be noted that the second step ST2 may be performed after the first step ST1 or may be performed before the first step ST1 . In fig. 5 shows the state of the wire working tool 1 after performing the first step ST1 and the second step ST2.

In the third step ST3, the distance between the first wire gripping tool 2 and the second wire gripping tool 4 is reduced to bend the wire W (see FIG. 6). The third step ST3 may be performed by shortening the first rod member 3. It should be noted that the third step ST3 (in other words, the wire W bending step) is performed in a connected state in which the movable portion 32 of the first rod member 3 and the second rod member 5 are connected to each other friend.

In the fourth step ST4, the wire W is cut at a location between the first wire gripping tool 2 and the second wire gripping tool 4 (for example, at the location indicated by arrow E in FIG. 6). As a result of cutting the wire W, a first cut end Wa and a second cut end Wb are formed in it (see Fig. 7).

In the fifth step ST5, the distance between the first cut end Wa and the second cut end Wb increases. In fig. 8 shows the state of the wire working tool 1 after the fifth step ST5 is executed.

The step of increasing the distance between the first cut end Wa and the second cut end Wb is performed by rotating the wire support tool 9 (specifically, the wire support tool 9 supporting the first wire W1 having the first cut end Wa), for example, around the first rod member 3 .

Alternatively and as shown, for example, in FIG. 9, the step of increasing the distance between the first cut end Wa and the second cut end Wb can be performed by attaching the first wire W1 having the first cut end Wa to the fastening tool 8.

It should be noted that the fifth step ST5 (in other words, the step of increasing the distance between the first cut end Wa and the second cut end Wb) may include increasing the distance between the first cut end Wa and the second cut end Wb by lengthening the first rod member, as shown , for example, in FIG. 10. The extension of the first rod member 3 is accomplished by moving the movable portion 32 relative to the main portion 30 in a connected state in which, for example, the movable portion 32 of the first rod member 3 and the second rod member 5 are connected to each other.

According to a first embodiment of the invention, the wire W can be bent by shortening the first rod element 3 (third step ST3). Moreover, according to the first embodiment of the invention, it is possible to increase the distance between the first cut end Wa and the second cut end Wb by performing a simple step or operation (fifth step ST5). Thus, using the wire cutting and dividing tool 1A according to the first embodiment of the invention and/or the wire cutting and separating method according to the first embodiment of the invention can perform a safe and efficient cutting and separating job of the wire W. In addition, the workload of the cutting worker is reduced. and wire separation W.

Wire connection method

A wire connecting method according to the first embodiment of the invention will be described with reference to FIG. 4 and 11 – 15. In Fig. 4 is a block diagram illustrating an example of a wire connecting method according to the first embodiment of the invention. In fig. 11 to 15 show schematically the steps of a wire connecting method according to the first embodiment of the invention.

The wire connecting method according to the first embodiment of the invention is carried out using a wire working tool 1. The wire working tool 1 used in the wire joining method according to the first embodiment of the invention may be the wire working tool 1A according to the first embodiment or another wire working tool.

When the "wire" is an "electrical wire", it is assumed that before performing the wire connecting method (in other words, the electric wire connecting method) from the first end of the first wire W1 (first cut end Wa) and the second end of the second wire W2 (second cut end Wb ) the insulating covering has been removed, and the first end Wa and the second end Wb have cores of wire W (ie, electric wire) without insulation.

In the sixth step ST6, the first end Wa of the first wire W1, grasped by the first wire gripping tool 2, is inserted into the first end Sa of the connecting sleeve SV (see FIG. 11). It should be noted that, for example, the sixth step ST6 is performed after the fifth step ST5 of the wire cutting and dividing method described above.

For example, the sixth step ST6 is performed by using the remote control means to insert the first end Wa of the first wire W1 into the first end Sa of the connecting sleeve SV.

In the seventh step ST7, the connecting sleeve SV is attached to the fastening tool 8 (see Fig. 13). Although it is preferable to execute step ST7 after executing step ST6, the seventh step ST7 can be performed before executing the sixth step ST6.

In the eighth step ST8, the fastening tool 8 and the connecting sleeve SV attached to the fastening tool 8 move in the first direction DR1, in other words, in the direction away from the second wire gripping tool 4 (see FIG. 14). Such movement is accomplished by the movement of the movable portion 32 relative to the main portion 30 in a divided state in which the movable portion 32 of the first rod member 3 and the second rod member 5 are separated from each other.

For moving the fastening tool 8 and the connecting sleeve SV in a separated state in which the movable portion 32 of the first rod member 3 and the second rod member 5 are separated from each other, the connected state between the movable portion 32 of the first rod member 3 and the second rod member 5 (in particular , the connected state by means of the connecting member 6 between the movable portion 32 of the first rod member 3 and the second rod member 5) is opened before executing the eighth step ST8. Such disconnection of the connected state may be performed before the seventh step ST7 or may be performed after the seventh step ST7. Moreover, such disconnection of the connected state may be performed before the sixth step ST6 or may be performed after the sixth step ST6.

In the example shown in FIG. 12, the connected state between the movable portion 32 of the first rod member 3 and the second rod member 5 is released by pulling the connecting member 6 (for example, the pin member 6a) that connects the movable portion 32 of the first rod member 3 and the second rod member 5 to each other at least at least from one of the movable section 32 of the first rod element 3 and the second rod element 5.

It should be noted that, as shown, for example, in FIG. 12, it is preferable that the action of pulling the connecting member 6 (for example, the pin member 6a) from at least one of the movable portion 32 of the first rod member 3 and the second rod member 5 is performed with the first force transfer surface 71t in contact with each other. the supporting member 7 and the second force transmitting surface 51t of the second rod member 5. In the state in which the first force transmitting surface 71t and the second force transmitting surface 51t are in contact with each other, at least part of the tensile force F acting on the first gripping tool 2 wires and the second wire gripping tool 4 will be carried by the support element 7. In this case, the force acting on the connecting element 6 becomes essentially zero or is reduced. Thus, it is possible to easily pull the connecting member 6 in a state in which the first force transmission surface 71t and the second force transmission surface 51t are in contact with each other.

In the example shown in FIG. 12, the connecting element 6 (in particular the pin element 6a) has been completely disconnected from both the movable portion 32 of the first rod element 3 and from the second rod element 5. Alternatively, the connecting element 6 (in particular the pin element 6a) can be is connected to the movable portion 32 of the first rod member 3 or to the second rod member 5 after breaking the connected state between the movable portion 32 of the first rod member 3 and the second rod member 5. In this case, the connecting member 6 will not be lost.

Then, in the ninth step ST9, the second end Wb of the second wire W2 grasped by the second wire gripping tool 4 is inserted into the second end Sb of the connecting sleeve SV (see FIG. 15). Preferably, the ninth step ST9 includes a step of extending the first rod member 3. The extension of the first rod member, in other words, the movement of the movable portion 32 in the second direction DR2, is performed, for example, in a divided state in which the movable portion 32 of the first rod member 3 and the second rod member 5 are separated from each other, or in a connected state in which the movable portion 32 of the first rod member 3 and the second rod member 5 are connected to each other.

Using the above steps, the first end Wa of the first wire W1 and the second end Wb of the second wire W2 are connected to each other using the connecting sleeve SV. It should be noted that after the ninth step ST9, the connecting sleeve SV can be crimped, the connecting sleeve SV and the first end Wa can be crimped together, and the connecting sleeve SV and the second end Wb can be crimped together.

In the wire connecting method according to the first embodiment of the invention, it is possible to insert the end of the first wire W1 into the first end Sa of the connecting sleeve SV by a simple operation (sixth step ST6). Moreover, in the example shown in FIG. 11, the portion of the first wire W1 inserted into the connecting sleeve SV (in particular, the portion without insulation) is straight or slightly curved. Therefore, the sixth step ST6 (in other words, the step of inserting the end of the first wire W1 into the connecting sleeve SV) can be easily performed, which greatly reduces the workload of inserting the end of the first wire W1 into the connecting sleeve SV. In addition, when inserting the end of the first wire W1 into the connecting sleeve SV, the worker is not required to occupy an awkward position or perform a complex operation. This allows the worker to make the wire connection safely and efficiently.

In the wire connecting method according to the first embodiment of the invention, it is possible to insert the end of the second wire W2 into the second end Sb of the connecting sleeve SV by a simple action or a simple operation (ninth step ST9). Moreover, in the example shown in FIG. 14 and 15, a portion of the second wire W2 located between the second wire gripping tool 4 and the connecting sleeve SV is straight or slightly curved. Therefore, the ninth step ST9 (in other words, the step of inserting the end of the second wire W2 into the connecting sleeve SV) can be easily performed, which greatly reduces the workload of inserting the end of the second wire W2 into the connecting sleeve SV. In addition, when inserting the end of the second wire W2 into the connecting sleeve SV, the worker is not required to occupy an awkward position or perform a difficult operation. This allows the worker to make the wire connection safely and efficiently.

Moreover, in the wire joining method according to the first embodiment of the invention, it is possible to move the movable portion 32 without changing the distance between the first wire gripping tool 2 and the second wire gripping tool 4 after cutting the wire W. Particularly, in the wire joining method according to the first embodiment of the invention, if the movable portion 32 moves relative to the main portion 30 in a separated state in which the movable portion 32 of the first rod member 3 and the second rod member 5 are separated from each other, the distance between the first wire gripping tool 2 and the second wire gripping tool 4 is not changes. In this case, the tensile force acting on the first wire W1 or the second wire W2 grasped by the first wire gripping tool 2 or the second wire gripping tool 4 does not change, or the bending amount of the first wire W1 or the second wire W2 does not change. Therefore, it is possible to carry out wire connection work more consistently and safely. In addition, if the bending amount of the first wire W1 or the second wire W2 is prevented from changing, the risk of the first wire W1 or the second wire W2 coming into contact with another wire or the like located below is reduced.

Second embodiment of the invention

The wire working tool 1B according to the second embodiment of the invention will be described with reference to FIG. 16 and 17. In FIG. 16 is a schematic side view of a wire working tool 1B according to the second embodiment of the invention. In fig. 17 is a schematic side view of an example of the first wire gripping tool 2.

For the second embodiment, features different from those of the first embodiment will be mainly described, while repeated description of components that have already been described for the first embodiment will be omitted. Therefore, it is obvious that components not explicitly described for the second embodiment of the invention, but already described for the first embodiment of the invention, can be used in the second embodiment of the invention.

The wire working tool 1B according to the second embodiment of the invention includes a first wire gripping tool 2, a first rod member 3, a second wire gripping tool 4, a second rod member 5, a connecting member 6, a support member 7 and a fastening tool 8. The working tool 1B for the wire may include a tool 9 for supporting the wire. In addition, the wire support tool 9 may include a first wire support tool 9a attached to the first rod member 3 (specifically, the main portion 30 of the first rod member 3), and a second wire support tool 9b attached to the second rod member. 5.

First tool 2 for gripping wire

The first wire gripping tool 2 includes a first gripping member 21 and a second gripping member 22, and clamps the first wire portion W with the first gripping member 21 and the second gripping member 22.

In the example shown in FIG. 17, the first gripping member 21 and the second gripping member 22 are connected to each other by a rotating member 23. In addition, a lever member 24 is rotatably connected to the rotating member 23. The lever element 24 is connected to the first rod element 3 via a first connecting portion 34.

When the first rod member 3 pulls the lever member 24, the rotary member 23 rotates around the first gripping member 21. In addition, when the rotary member 23 is rotated about the first gripping member 21, it reduces the distance between the clamping surface of the first gripping member 21 and the clamping surface of the second gripping member 22. Thus, the wire W is clamped by the first gripping member 21 and the second gripping member 22.

In the example shown in FIG. 17, the first wire gripping tool 2 has a locking member 25 and a control member 26 that controls the locking member 25. The locking member 25 limits the increase in the distance between the gripping surface of the first gripping member 21 and the gripping surface of the second gripping member 22. In the example shown in FIG. 17, the locking member 25 is attached to the lever member.

When the control member 26 is operated by a remote control means or the like, the tip of the locking member moves toward the rotary member 23. The tip of the locking member 25 comes into contact with the rotary member 23, thereby limiting the rotation of the rotary member 23. Thus, the increase in the distance between the gripping surface of the first gripping member 21 and the gripping surface of the second gripping member 22 is limited.

It should be noted that in the example shown in FIG. 17, the pivot member 23 includes a first pivot member 23a and a second pivot member 23b positioned substantially parallel to the first pivot member 23a. In addition, the first rotary member 23a, the second rotary member 23b, the first gripping member 21 and the lever member 24 form a hinged parallelogram. In the example shown in FIG. 17, although the first wire gripping tool 2 includes two rotary members 23a, 23b, the first wire gripping tool 2 may include one rotary member.

In the example shown in FIG. 17, the first wire gripping tool 2 includes an anti-fall member 29 that prevents a wire disposed between the first gripping member 21 and the second gripping member 22 from falling out of the first wire gripping tool 2. In the example shown in FIG. 17, the anti-fall member 29 is supported by a rotatable member 23 (specifically, a second pivot member 23b) about a first axis AT1, and is supported by a second gripping member 22 that is rotatable about a second axis AT2.

First rod element 3

In the example shown in FIG. 16, the main portion 30 of the first rod member 3 is connected to the first wire gripping tool 2 via the first connecting portion 34. In the example shown in FIG. 16, the connection between the first rod member 3 and the first wire gripping tool 2 may be a rotary connection. In particular, the first rod element 3 can be rotated about an axis AX1 perpendicular to the longitudinal axis AX of the first rod element 3 relative to the first wire gripping tool 2. It should be noted that although in the example shown in FIG. 16, the first rod member 3 and the first wire gripping tool 2 are connected by a pin member, the first rod member 3 and the first wire gripping tool 2 may be connected by a hook member.

The first rod member includes a main portion 30 and a movable portion 32. The first rod member 3 can be lengthened and shortened depending on the relative movement of the movable portion 32 relative to the main portion 30. The first rod member 3 includes a coupling mechanism (gear mechanism, screw mechanism, or the like). .), which connects the main section 30 and the movable section 32 with each other with the possibility of relative movement, while the first rod element 3 is lengthened or shortened depending on the action of the actuator 300 installed on the main section 30.

Below is a description of an example of a mechanism for lengthening and shortening the telescopic first rod member 3 using a remote control means. As an example, it is assumed that (A) a first bevel gear that rotates about the rotation axis R1 together with the actuator 300 is located on the actuator 300, (B) a second gear gear connected to the first gear gear so that it can transmit load is located inside the main portion 30, (C) the second bevel gear rotates about the longitudinal axis AX of the first rod member 3 together with a threaded rod having a male thread located on the outer periphery, while (D) the movable portion 32 is threadedly connected to threaded rod. In this case, when the actuator 300 is rotated about the rotation axis R1 by the remote control element, it causes the first bevel gear to rotate about the rotation axis R1 and the second bevel gear to rotate about the longitudinal axis AX. Rotation of the second bevel gear about the longitudinal axis AX causes the threaded rod to rotate about the longitudinal axis AX. Rotation of the threaded rod about the longitudinal axis AX causes the movable portion 32 threadedly attached to the threaded rod to move in a direction of retraction into the main portion 30 (or in a direction of protrusion from the main portion 30). In this way, the rod element 3 is shortened.

Second tool 4 for gripping wire

The second wire gripping tool 4 includes a first gripping member 41 and a second gripping member 42, and clamps the second wire portion W with the first gripping member 41 and the second gripping member 42.

In the example shown in FIG. 16, the second wire gripping tool 4 includes a rotary member 43, a lever member 44, a locking member 45, a control member 46, and a fall-preventing member 49. The “pivot member 43,” the “first pivot member 43a,” the “second pivot member 43b,” “lever member 44”, “stopper member 45”, “control member 46” and “fall-preventing member 49” are the same as “pivot member 23”, “first pivot member 23a”, “second pivot member 23b” , “lever member 24”, “stopper member 25”, “control member 26” and “fall-preventing member 29”, respectively, described above. Therefore, repeated description of these elements is omitted.

In the example shown in FIG. 16, the second connecting portion 54 includes a hook member 54a attached to the second rod member 5, a closure member 54b that can close the throat of the hook member 54a, and a control portion 54c used to control the closure member 54b. In addition, by controlling the control portion 54c to open the closing member 54b, the second wire gripping tool 4 can be engaged with the hook member 54a.

In the example shown in FIG. 16, the second rod member 5 and the second wire gripping tool 4 are releasably connected to each other by means of a hook member 54a. Although in the example shown in FIG. 16, the second rod member 5 and the second wire gripping tool 4 are connected by a hook member 54a, the second rod member 5 and the second wire gripping tool 4 may be connected by a pin member.

In the example shown in FIG. 16, the support end of the second rod member 5 (the end in the second direction DR2) is connected to the second wire gripping tool 4, and the tip of the second rod member 5 (the end in the first direction DR1) is connected to the movable portion 32 of the first rod member 3 through the connecting member 6 with the possibility of disconnection.

Support element 7

In the example shown in FIG. 16, the support member 7 includes a first rod-shaped portion 70a and a second rod-shaped portion 70b parallel to the first rod-shaped portion 70a. In addition, the first rod-shaped portion 70a and the second rod-shaped portion 70b are arranged parallel to the longitudinal axis AX of the first rod member 3.

When the supporting member 7 includes a first rod-shaped portion 70a and a second rod-shaped portion 70b, the bending rigidity of the supporting member 7 is increased. Moreover, when the supporting member 7 includes a first rod-shaped portion 70a and a second rod-shaped portion 70b, a tensile force acting on the first tool 2 for the wire gripping tool 4 and the second wire gripping tool 4 are supported by the first rod-shaped portion 70a and the second rod-shaped portion 70b as a distributed load. Therefore, the safety and reliability of the wire working tool 1B are improved.

In the example shown in FIG. 16, the tip of the first rod member 3 (in other words, the portion connected to the second rod member 5) and the tip of the second rod member 5 (in other words, the portion connected to the first rod member 3) are located between the first rod-shaped portion 70a and the second rod-shaped portion 70b . Thus, the tip of the first rod member 3 and the tip of the second rod member 5 are protected by the first rod-shaped portion 70a and the second rod-shaped portion 70b.

It should be noted that although in the example shown in FIG. 16, the support element includes two rod-shaped sections 70a, 70b, the support element 7 may contain one or three or more rod-shaped sections.

First connecting section 71

Moreover, it is preferable that the restriction member 100 is disposed between the first connecting portion 71 and the second connecting portion 51 in the state in which the first step ST101 and the second step ST102 were performed.

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

In the fifth step ST105, the distance between the first wire gripping tool 2 and the second wire gripping tool 4 is reduced to bend the wire W (see FIG. 19(b)).

The fifth step ST105 may be performed by controlling the actuator 300 to shorten the first rod member 3. Note that the fifth step ST105 (in other words, the wire W bending step) is performed in a connected state in which the movable portion 32 of the first rod member 3 and the second rod member element are connected to each other.

In the sixth step ST106, the wire W is cut at a location between the first wire gripping tool 2 and the second wire gripping tool 4, particularly at a location between the first wire supporting tool 9a and the second wire supporting tool 9b (for example, at the location indicated by the arrow E in Fig. 19(b)). By cutting the wire W, a first cut end Wa and a second cut end Wb are formed at the wire W (see FIG. 19(c)).

In the seventh step ST107, the distance between the first cut end Wa and the second cut end Wb is increased. In fig. 19(d) shows the state of the wire working tool 1 after execution of the seventh step ST107.

The step of increasing the distance between the first cut end Wa and the second cut end Wb is performed by rotating the first wire support tool 9a that supports the first wire W1 having the first cut end Wa or the second wire support tool 9b that supports the second wire W2 having a second cut end Wb, around, for example, the longitudinal axis of the first rod element 3 or the second rod element 5. In the example shown in FIG. 19(d), the distance between the first cut end Wa and the second cut end Wb is increased by rotating the first wire support tool 9a about the longitudinal axis AX of the first rod member 3.

It should be noted that the seventh step ST107 (in other words, the step of increasing the distance between the first cut end Wa and the second cut end Wb) may include increasing the distance between the first cut end Wa and the second cut end Wb by lengthening the first rod member 3 as is shown as an example in FIG. 20(a). The extension of the first rod element 3 is performed by moving the movable portion 32 relative to the main portion 30 in a connected state in which the movable portion 32 of the first rod element 3 and the second rod element 5 are connected to each other. In addition, in the seventh step ST107, the restriction member 100 located between the first connecting portion 71 and the second connecting portion 51 can be removed.

According to the second embodiment of the invention, the wire W can be bent by shortening the first rod element 3 (fifth step ST105). In addition, in the second step, the distance between the first cut end Wa and the second cut end Wb can be increased by a simple action or operation (seventh step ST107). Thus, the use of the wire working tool 1B and/or the wire cutting and separating method according to the second embodiment of the invention enables the cutting and separating work of wire W to be performed safely and efficiently. In addition, the workload of the worker performing the cutting and separating of wire W is reduced.

Wire connection method

A wire connecting method according to the second embodiment of the invention will be described with reference to FIG. 18 and 20–22. In fig. 18 is a block diagram illustrating an example of a wire connecting method according to the second embodiment of the invention. In fig. 20 to 22 show schematically the steps of a wire connecting method according to the second embodiment of the invention.

The wire connecting method according to the second embodiment of the invention is carried out using a wire working tool 1. The wire working tool 1 used in the wire joining method according to the second embodiment of the invention may be the wire working tool 1B according to the second embodiment of the invention or another wire working tool.

When the "wire" is an "electrical wire", it is assumed that before performing the wire connecting method (in other words, the electric wire connecting method) from the first end of the first wire W1 (first cut end Wa) and the second end of the second wire W2 (second cut end Wb ) the insulation coating has been removed, and the first end Wa and the second end Wb have wire cores W (ie, electric wire) without insulation (see FIG. 20(a)).

In the eighth step ST108, the first end Wa of the first wire W1, grasped by the first wire gripping tool 2, is inserted into the first end Sa of the connecting sleeve SV (see FIG. 20(b)). It should be noted that, for example, the eighth step ST108 is performed after the seventh step ST107 of the wire cutting and dividing method described above.

For example, the eighth step ST108 is performed by using the remote control means to insert the first end Wa of the first wire W1 into the first end Sa of the connecting sleeve SV.

In the ninth step ST109, the connecting sleeve SV is attached to the fastening tool 8 (see Fig. 20(c)). For example, the step of attaching the connecting sleeve SV to the fastening tool 8 is performed by using the actuator 83 to control the fastening tool to reduce the distance between the first clamping element 81 and the second clamping element 82. Although it is preferable that the ninth step ST109 is performed after the eighth step ST108, the ninth step ST109 may be executed before the eighth step ST108 is executed.

It should be noted that when the position of the fastening tool is changed along the longitudinal axis AX of the first rod member 3 relative to the movable portion 32, the position of the fastening tool 8 relative to the movable portion 32 can be adjusted (in other words, the position of the fastening tool 8 relative to the movable portion 32 can be changed) before performing ninth stage ST109.

In the tenth step ST110, the connected state between the movable portion 32 of the first rod member 3 and the second rod member (specifically, the connected state by the connecting member 6) is released (see FIG. 20(c)). Such opening of the connected state is accomplished by pulling the connecting element 6 (for example, the pin element 6a) from at least one of the components, which include, for example, the first rod element 3 and the second rod element 5. It should be noted that it is preferable that the opening of the connected the state between the movable portion 32 of the first rod member 32 and the second rod member 5 was performed in a state in which the first connecting portion 71 and the second connecting portion 51 are in contact with each other.

Such disconnection of the connected state may be performed before the ninth step ST109 or may be performed after the ninth step ST 109. Moreover, release of the connected state may be performed before the eighth step ST108 or may be performed after the eighth step ST108.

In the eleventh step ST111, the fastening tool 8 and the connecting sleeve SV attached to the fastening tool 8 move in the direction from the second wire gripping tool 4 (see FIG. 21(a)). This movement is performed by moving the movable portion 32 relative to the main portion 30 in a divided state in which the movable portion 32 of the first rod member 3 and the second rod member 5 are separated from each other. Specifically, when the movable portion 32 moves toward the main portion 30, the pressure portion 32a of the movable portion 32 exerts pressure on the pressure portion 80a of the fastening tool 8. As a result, the fastening tool 8 moves toward the main portion 30 (in other words, away from the second tool 4 for gripping the wire).

In the twelfth step ST112, the second end Wb of the second wire W2, grasped by the second wire gripping tool 4, is moved in the direction facing the second end Sb of the connecting sleeve SV (see FIG. 21(b)). Such movement is performed using, for example, a remote control tool. The twelfth step ST112 may include detaching the second wire W2 from the second wire support tool 9b (specifically, moving the second wire W2 from the receiving space SP2 of the second wire support tool 9b).

In the thirteenth step ST113, the second end Wb of the second wire W2, grasped by the second wire gripping tool 4, is inserted into the second end Sb of the connecting sleeve SV (see FIG. 21(c)). The thirteenth step ST113 includes moving the fastening tool 8 and the connecting sleeve attached to the fastening tool 8 towards the second wire gripping tool 4. Such movement may include sliding movement of the fastening tool 8 relative to the movable portion 32 of the first rod member 3 through the use of remote control means or the like. Alternatively, when the fastening tool 8 is attached to the movable portion 32 of the first rod element 3, such movement may be accomplished by extending the first rod element 3, in other words, by moving the movable portion 32 relative to the main portion 30.

After performing the thirteenth step ST113, when the insertion amount of the first end Wa of the first wire W1 and/or the second end Wb of the second wire W2 into the connecting sleeve SV is insufficient, inserting the first end Wa of the first wire W1 and/or the second end Wb of the second wire W2 into the connecting sleeve SV may help to reduce the distance between the first wire gripping tool 2 and the second wire gripping tool 4 (see FIG. 22). This reduction in the distance between the first wire gripping tool 2 and the second wire gripping tool 4 can be accomplished by shortening the first rod tool 3 after connecting the movable portion 32 of the first rod member 3 and the second rod member 5 to each other by using a connecting member 6. It should be noted that the connection between the movable portion of the first rod element and the second rod element 5 is made by inserting a pin element 6a, for example, into both the movable portion 32 and the second rod element 5.

Using the above steps, the first end Wa of the first wire W1 and the second end Wb of the second wire W2 are connected to each other using a connecting sleeve SV. It should be noted that after the thirteenth step ST113, the connecting sleeve SV can be crimped, the connecting sleeve SV and the first end Wa can be crimped together, and the connecting sleeve SV and the second end Wb can be crimped together.

In the wire connecting method according to the second embodiment of the invention, it is possible to insert the end of the first wire W1 into the first end Sa of the connecting sleeve SV by a simple operation (eighth step ST108). In addition, when inserting the end of the first wire W1 into the connecting sleeve SV, the worker is not required to occupy an awkward position or perform a complex operation. This allows the worker to make the wire connection safely and efficiently.

In the wire connecting method according to the second embodiment of the invention, it is possible to insert the end of the second wire W2 into the second end Sb of the connecting sleeve SV by a simple action or a simple operation (thirteenth step ST113). In addition, when inserting the end of the second wire W2 into the connecting sleeve SV, the worker is not required to occupy an awkward position or perform a difficult operation. This allows the worker to make the wire connection safely and efficiently.

Modified Example of the Second Embodiment

In fig. 16 shows an example in which the support member 7 (specifically, the first rod-shaped portion 70a and the second rod-shaped portion 70b) is attached to the stationary portion 30 of the first rod-shaped element 3 by means of a connecting block 39. In the example shown in FIG. 16, the end in the first direction DR1 of the support member 7 is attached to the connection block 39. Alternatively, as an example in FIG. 23 shows that the support element 7 can be extended such that it extends through the connecting block 39, wherein the end in the first direction DR1 of the supporting element 7 (in particular, the first rod-shaped portion 70a and the second rod-shaped portion 70b) can be attached to the second connecting block 38. In the example shown in FIG. 23, the second connection block 38 is attached to an end portion 30s of the main portion 30 where the actuator 300 is located. Alternatively, the second connection block 38 may be integrally formed with the end portion 30s.

Additionally, or alternatively, as exemplified in FIG. 24, when the end in the first direction DR1 of the support member 7 (specifically, the first rod-shaped portion 70a and the second rod-shaped portion 70b) is attached to the second connecting block 38, the connecting block 39 (see FIG. 23) may be missing.

Third embodiment of the invention

The wire working tool 1C according to the third embodiment of the invention will be described with reference to FIG. 25 and 26. In FIG. 25 and 26 are schematic side views of the wire working tool 1C according to the third embodiment of the invention.

For the third embodiment, features different from those of the first embodiment and the second embodiment will be mainly described, and repeated descriptions of components that have already been described for the first embodiment or the second embodiment will be omitted. Therefore, it is apparent that components not expressly described for the third embodiment, but already described for the first embodiment or the second embodiment, may be used in the third embodiment.

The wire working tool 1C according to the third embodiment of the invention differs from the wire working tool 1A according to the first embodiment of the invention (or the wire working tool 1B according to the second embodiment of the invention) in that the first rod member 3 has a second movable portion 32' moving in the second direction DR2, which is the opposite direction to the first direction DR1 when the movable portion 32 moves in the first direction DR1.

In the example shown in FIG. 25, the first rod element 3 includes a movable section 32, a main section 30 and a second movable section 32'. For example, the main portion 30 is attached to the support member 7 (specifically, the first rod-shaped portion 70a and the second rod-shaped portion 70b).

In the example shown in FIG. 25, the main portion 30 includes an actuator 300. The first rod element 3 is lengthened and shortened according to the action of the actuator 300 mounted on the main portion 30. The actuator 300 is controlled, for example, by a remote control means. The mechanism for moving the movable portion 32 in the first direction DR1 (or the second direction DR2) relative to the main portion 30 in accordance with the operation of the actuator 300 has already been described for the first embodiment and the second embodiment. Thus, repeated description of the mechanism for causing the movement of the movable portion 32 will be omitted. In the example shown in FIG. 25, the second movable portion 32' moves in the second direction DR2 (or the first direction DR1) relative to the main portion 30 in accordance with the action of the actuator 300. A mechanism for causing the second movable portion 32' to move in the second direction DR2 (or the first direction DR1) relative to the main portion 30 is the same as the mechanism for causing the movable portion 32 to move in the first direction DR1 (or in the second direction DR2) relative to the main portion 30.

It should be noted that the first rod member 3 may include a left-hand threaded portion such that the second movable portion 32' moves in a second direction DR2 relative to the main portion 30 when the movable portion 32 moves in the first direction DR1 relative to the main portion 30 (or so that the second movable portion 32' has moved in the first direction DR1 relative to the main portion 30 when the movable portion 32 moves in the second direction DR2 relative to the main portion 30). In this case, when the threaded portion drives the movable portion 32 in the first direction DR1, the left-hand threaded thread portion drives the second movable portion 32' in the second direction DR2.

In the example shown in FIG. 25, the fastening tool 8 (in particular, the first fastening tool 8a) is located on the movable section 32, and the fastening tool 8 (in particular, the second fastening tool 8b) is located on the second movable section 32'. Although in the example shown in FIG. 25, the first fastening tool 8a is attached to the movable portion 32, the first fastening tool 8a can be slidably moved relative to the movable portion 32. Similarly, although in the example shown in FIG. 25, the second fastening tool 8b is attached to the second movable portion 32', the second fastening tool 8b can be slidably moved relative to the second movable portion 32'. The second wire W2 having a second cut end Wb is attached, for example, to the first fastening tool 8a, and the first wire W1, having a first cut end Wa, is attached, for example, to the second fastening tool 8b. Although in the example shown in FIG. 25, the first fastening tool 8a is attached to the tip 32t of the movable portion 32, the first fastening tool 8a may be attached to the middle portion of the movable portion 32. Although in the example shown in FIG. 25, the second fastening tool 8b is attached to the tip of the second movable portion 32', the second fastening tool 8b may be attached to the middle part of the second movable portion 32'.

In the example shown in FIG. 25, the fastening tool 8 (in particular, the third fastening tool 8c) is located on the main portion 30. Although in the example shown in FIG. 25, the third fastening tool 8c is attached to the main portion 30, the third fastening tool 8c may be attached to the supporting member 7 (specifically, the first rod-shaped portion 70a and the second rod-shaped portion 70b). For example, the connecting sleeve SV is attached to the third fastening tool 8C.

In the example shown in FIG. 25, the first rod-shaped portion 70a includes a first portion 70a-1 and a second portion 70a-2. In addition, the end in the first direction DR1 of the first portion 70a-1 is connected to the main portion 30 (specifically, the middle portion 30m of the main portion 30 where the actuator 300 is located), and the end in the DR2 direction of the second portion 70a-2 is connected to the main portion 30. section 30 (in particular, with the middle part 30m of the main section 30, where the actuator 300 is located). Although the first rod-shaped portion 70a includes two rod-shaped components (specifically, the first portion 70a-1, which is a rod-shaped component, and the second portion 70a-2, which is a rod-shaped component), located in a straight line in the example shown in fig. 25, the first rod-shaped portion 70a may be formed as a separate rod-shaped component. Likewise, the second rod-shaped portion 70b may be formed from two rod-shaped components arranged in a straight line, or may be a separate rod-shaped component.

In the example shown in FIG. 25, each of the components comprising the first fastening tool 8a, the second fastening tool 8b and the third fastening tool 8c may have the same structure as the fastening tool 9 shown as an example in FIG. 1(a). In other words, each of the components comprising the first fastening tool 8a, the second fastening tool 8b, and the third fastening tool 8c may include a connecting portion 80, a first clamping portion 81, a second clamping portion 82, and an actuator 83 for controlling the fastening tool.

Below is a description of a wire cutting and dividing method according to the third embodiment of the invention. In the wire cutting and separating method according to the third embodiment of the invention, first of all, the first wire gripping tool 2 is attached to the wire W, and the second wire gripping tool 4 is attached to the wire W. Before attaching the wire gripping tools 2, 4 to the wire or after fastening, the wire W may be supported by the first wire support tool 9a and/or the second wire support tool 9b. The first rod member 3 is then shortened to bend the wire W. Shortening the first rod member 3 involves moving the movable portion 32 in the first direction DR1 and at the same time moving the second movable portion 32' in the second direction DR2. Shortening of the first rod element 3 is performed in a connected state, in which the movable portion 32 of the first rod element 3 and the second rod element 5 are connected to each other. Then, the wire W is cut at a location between the first wire gripping tool 2 and the second wire gripping tool 2. As a result of such cutting, a first cut end Wa and a second cut end Wb are formed. Then, the distance between the first cut end Wa and the second cut end Wb is increased. This increase in distance is achieved by rotating the first wire support tool 9a or the second wire support tool 9b, for example, around the longitudinal axis of the first rod element 3.

Below is a description of an example of a rein connection method according to the third embodiment of the invention. In the drive connecting method according to the third embodiment of the invention, first of all, the connecting sleeve SV is attached to the third fastening tool 8c. The first wire W1 is attached to the second fastening tool 8b before or after attaching the connecting sleeve SV to the third fastening tool 8c. In addition, the second wire W2 is attached to the first fastening tool 8a before or after attaching the connecting sleeve SV to the third fastening tool 8c. In fig. 26 shows a state in which the connecting sleeve SV has been attached to the third fastening tool 8c, the first wire W1 has been attached to the second fastening tool 8b, and the second wire W2 has been attached to the first fastening tool 8a. Then, the first end Wa of the first wire W1, grasped by the first wire gripping tool 2, is inserted into the first end Sa of the connecting sleeve SV, and the second end Wb of the second wire W2, grasped by the second wire gripping tool 4, is inserted into the second end Sb of the connecting sleeve SV. Insertion of the first end Wa of the first wire W1 and the second end Wb of the second wire W2 into the connecting sleeve SV is performed, for example, by shortening the first rod element 3. Shortening the first rod element 3 involves moving the movable portion 32 in the first direction DR1 and at the same time moving the second movable portion 32' in the second direction DR2. The shortening of the first rod element 3 is performed in a state in which the connection between the movable portion 32 of the first rod element 3 and the second rod element 5 is open (specifically, in the state in which the connecting element 6 does not connect the movable portion 32 of the first rod element 3 and the second rod element element 5 with each other). In the example shown in FIG. 26, the first fastening tool 8a is attached to the movable portion 32, and the second fastening tool 8b is attached to the second movable portion 32'. Thus, when the movable portion 32 moves in the first direction DR1, it causes the second end Wb of the second wire W2 attached to the first fastening tool 8a to move in the first direction DR1. As a result, the second end Wb is inserted into the connecting sleeve SV. Similarly, when the second movable portion 32' moves in the second direction DR2, it causes the first end Wa of the first wire W1 attached to the second fastening tool 8b to move in the second direction DR2. As a result, the first end Wa is inserted into the connecting sleeve SV. After inserting the first end Wa of the first wire W1 and the second end Wb of the second wire W2 into the connecting sleeve SV, the connecting sleeve SV can be crimped.

The third embodiment provides the same advantageous effects as the first embodiment or the second embodiment. Moreover, according to the third embodiment of the invention, the first rod member 3 of the wire working tool 1C includes a movable portion 32 and a second movable portion 32'. In this case, it is possible to simultaneously drive the first end Wa of the first wire W1 and the second end Wb of the second wire W2 (for example, to simultaneously insert the first end Wa and the second end Wb into the connecting sleeve SV).

Wire Tool Component

In the wire working tool according to the embodiments described above, components of existing wire cutting and separating tools can be used without modification for the first wire gripping tool 2, the second wire gripping tool 4, the main portion 30 of the first rod member 3, and the tool 9 to support the wire. In other words, in the above-described embodiments, existing components may be used for the first wire gripping tool 2, the second wire gripping tool 4, the main portion 30 of the first rod member 3, and the wire support tool 9, and new components may be used for the moving member 32. , forming part of the first rod element 3 (in other words, one or more movable elements that can move relative to the main portion 30 of the first rod element 3), the second rod element 5, the connecting element 6, which connects the movable element 32 and the second rod element 5 each with each other with the possibility of separation, and the supporting element 7. Of course, at least one of the components, which includes a first wire gripping tool 2, a second wire gripping tool 4, a main portion 30 of the first rod element 3, a wire support tool 9 and fastening tool 8 may be formed from a new component instead of an existing component.

It should be noted that the present invention is not limited to the above-described embodiments. Any combination of some of the above-described embodiments, or otherwise modification of any component, or omission of any component of each embodiment, is possible within the scope of the present invention. In addition, any component may be added to each of the above components.

For example, in FIG. 2 shows an example in which the connecting element 6 is completely disconnected from the movable portion 32 of the first rod element 3 and the second rod element 5. Alternatively and as shown by way of example in the lower view of FIG. 27, the connecting element 6 (for example, the pin element 6a) can be designed so that it does not become detached from the movable portion 32 of the first rod element 3 or the second rod element 5 (in other words, so that it does not fall out of the movable portion 32 of the first rod member 3 or the second rod member 5) even in a state in which the connection between the movable portion 32 of the first rod member 3 and the second rod member 5 is open. In the example shown in FIG. 27, the wire working tool has a cam member 60 that changes the position of the connecting member 6 (specifically, the pin member 6a), and an actuator portion 61 used to control the cam member 60 by using the remote control means. In the example shown in FIG. 27, rotation of the cam member 60 about the rotation axis R2 causes the position of the connecting member 6 (in particular, the pin member 6a) to change between a connected position for connecting the movable portion 32 of the first rod member and the second rod member 5 to each other and a connection release position for releasing the connection. between the movable portion 32 of the first rod element 3 and the second rod element 5. Alternatively, the position of the connecting element 6 (in particular, the pin element 6a) can be changed between the connected position and the disconnected position due to the sliding movement of the cam element 60. In addition, the connecting member 6 can be pushed in the direction of approaching the connection opening position from the connected position by the pushing member.
