Description

The present invention relates to an electric wire, and more particularly to an electric wire that can be extended in both the vertical direction and the horizontal direction.

Electric wires that can be extended in the longitudinal direction have been conventionally used for wiring of OA equipment and industrial machines. Various configurations of electric wires having such elasticity have been proposed so far.

For example, the telescopic electric wire proposed in Patent Document 1 is used for wiring of robots, wearable electronic devices, and the like. This telescopic electric wire is composed of an elastic core portion, a conductor portion composed of a conductor wire wound and / or braided around the outer circumference of the elastic core portion, and an elastic resin formed on the outer circumference of the conductor portion. It is composed of a first outer coating layer and a second outer coating layer composed of fibers formed on the outer periphery of the first outer coating layer.

On the other hand, in the field of woven fabrics and knitted fabrics, making woven fabrics and knitted fabrics conductive has come to be carried out.

Patent Document 2 proposes a conductive woven or knitted fabric. In this conductive woven knitted fabric, a plurality of warp threads arranged along the longitudinal direction, a plurality of weft threads knitted on the warp threads, and at least one conductive wire arranged and woven along the longitudinal direction are formed. It is constructed by being woven in a planar shape. Then, the conductive wire is knitted into the warp and / or the weft, and the conductive wire weaving section is integrally restrained by the conductive woven or knitted fabric, and the conductive wire is not knitted by the warp and / or the weft, and is outside the conductive woven or knitted fabric. It is configured to have a conductive wire exposed section that is exposed by a predetermined length. In Patent Document 2, it is also proposed to fold the conductive wire into a wavy structure.

Japanese Unexamined Patent Publication No. 2011-82050 Special Table 2013-517389

The telescopic electric wire proposed by Patent Document 1 expands and contracts only in the longitudinal direction. Further, since this telescopic electric wire has a structure in which the conductor portion is wound around the core portion as described above, the expansion / contraction rate cannot be increased unless the core portion is thickened. Further, in the structure of this telescopic electric wire, the telescopic electric wire cannot be directly connected to the fibers constituting the clothing, and special processing is required for the connection.

On the other hand, the conductive woven or knitted fabric proposed by Patent Document 2 is a woven fabric in which the fabric forming the base material is composed of warp threads extending linearly in the vertical direction and weft threads extending linearly in the horizontal direction. Conductive wires are woven into these fabrics. Therefore, this conductive woven or knitted fabric hardly expands or contracts in both the vertical direction and the horizontal direction. Therefore, it is difficult to use this conductive woven or knitted fabric as a stretchable electric wire.

The present invention has been made to solve the above problems, and an object thereof is an electric wire that can be used in various industrial fields and can be extended in both a longitudinal direction and a direction orthogonal to the longitudinal direction. Is to provide.

The electric wire according to the present invention for solving the above-mentioned problems has a plurality of conductive wires extending in a predetermined direction and a knitted fabric in which fibers are woven and the conductive wires are held by the fibers, and the plurality of conductive wires are held. The line has a waveform that oscillates in a direction orthogonal to the predetermined direction, and is characterized in that the waveform extends in the predetermined direction by being connected to each other in the predetermined direction.

According to the present invention, a plurality of conductive wires each have a waveform that oscillates in a direction orthogonal to a predetermined direction, and the waveforms are connected in a predetermined direction to extend in a predetermined direction. When a tensile force is applied, it is possible to extend the electric wire by widening the interval between the waveforms in a predetermined direction. Further, since the conductive wire is held by the knitted fabric, even when a tensile force is applied in a direction orthogonal to the predetermined direction, the elasticity of the knitted fabric can be used to freely move in the direction orthogonal to the predetermined direction. It can be stretched to.

In the electric wire according to the present invention, the fibers constituting the knitted fabric are conductive fibers having conductivity, and the conductive fibers are crimped, and the conductive fibers are said to be the conductive fibers in the conductive wire. The waveforms adjacent to each other in a predetermined direction are connected to each other.

According to the present invention, the crimped conductive fibers connect the corrugations adjacent to each other in a predetermined direction on the conductive wire, so that when a tensile force is applied to the electric wire, the shrinkage elongation of the conductive fibers is utilized. As a result, the electric wire can be extended in either a predetermined direction or a direction orthogonal to the predetermined direction. Further, even when the electric wire is stretched, since the conductive fibers connect the waveforms adjacent to each other in the predetermined direction in the conductive wire, it is possible to suppress an extremely increase in the resistance value.

In the electric wire according to the present invention, the conductive wires intersect with each other and are in contact with each other.

According to the present invention, since the conductive wires intersect with each other and are in contact with each other, even if the conductive wires are physically cut in the middle of the longitudinal direction, it is possible to suppress the occurrence of electrical disconnection. It is possible.

The electric wire according to the present invention is further provided with one or more auxiliary conductive wires extending in the predetermined direction, and the auxiliary conductive wires have at least a waveform oscillating in a direction orthogonal to the predetermined direction. The two conductive wires are connected to each other.

According to the present invention, since the auxiliary conductive wires connect the conductive wires to each other, the resistance value of the electric wire can be reduced as compared with the electric wire not provided with the auxiliary conductive wire.

In the electric wire according to the present invention, the conductive fibers are knitted on both sides of the conductive wire in a direction orthogonal to the predetermined direction.

According to the present invention, it is possible to prevent the conductive fibers from being extremely widened in the interval of the waveform formed by the conductive wire and being extremely deformed. Therefore, even when a large tensile force is applied to the electric wire, it is possible to prevent the conductive wire from being broken.

In the electric wire according to the present invention, the conductive fibers may be knitted vertically.

According to the present invention, since the fabric portion is constructed by vertically knitting conductive fibers, it is possible to increase the conductivity as compared with the case where the fabric portion is constructed by weft knitting. When the electric wire is manufactured by knitting the conductive fiber, it can be manufactured by weft-knitting or the weft-knitting of the conductive fiber. However, when the electric wire is constructed by weaving the conductive fibers as in the present invention, it can be configured more efficiently than when the conductive fibers are weft-knitted, and the cost is suppressed. Will be possible.

According to the present invention, it is possible to provide an electric wire extending in both a longitudinal direction and a direction orthogonal to the longitudinal direction, which can be used in various industrial fields.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The technical scope of the present invention is not limited to the following description and drawings.

[Basic configuration]
As shown in FIGS. 1 and 2, the electric wire 1 according to the present invention includes a plurality of conductive wires 10 extending in a predetermined direction X and a knitted wire 30 in which fibers 20 are woven and the conductive wires 10 are held by the fibers 20. have. Each of the plurality of conductive wires 10 has a waveform that oscillates in a direction Y orthogonal to the predetermined direction X, and the waveforms are connected in the predetermined direction X to extend in the predetermined direction X.

Hereinafter, the specific configuration of the electric wire 1 will be described with reference to the drawings as appropriate.

(Conducting wire)
As shown in FIGS. 1 and 2, two conductive wires 10 are provided, and the conductive wires 10 are structurally arranged in parallel. Each conductive wire 10 extends in a predetermined direction (hereinafter, referred to as “predetermined direction X”) represented by reference numeral X in FIGS. 1 and 2. Further, each conductive wire 10 forms a waveform so as to oscillate in a direction orthogonal to a predetermined direction (hereinafter, referred to as "direction Y" or "Y direction"). The two conductive wires 10 are in contact with each other so that the conductive wires 10 adjacent to each other intersect with each other. The conductive wires intersect at a plurality of positions in the X direction.

The two conductive wires 10 are arranged so that the centers of the amplitudes of the respective conductive wires 10 are separated by a certain distance. The distance between the centers of the amplitudes of the conductive wires 10 is the same as or shorter than the amplitude of the waveform formed by the conductive wires 10. Further, the phases of the waveforms are arranged so as to be shifted in the predetermined direction X. In the two conductive wires 10, the distance between the centers of the amplitudes of the respective conductive wires 10 and the phase of the waveform are configured in this way. Therefore, when the two conductive wires 10 intersect, the waveforms become compatible with each other. Contact. Although not particularly shown in the drawings, the conductive wires 10 may be arranged so that the vertices of the waveform are in contact with each other.

As described above, the conductive wires 10 are in contact with each other, so that even if the conductive wires 10 and the conductive fibers 20 are partially in contact with each other, the conductive wires 10 flow through the conductive wires 10. The current can be dispersed and flowed. Further, since the distance between the centers of the amplitudes of the conductive wires 10 (distance in the Y direction) is the same as or shorter than the amplitude of the waveform formed by the conductive wires 10, the adjacent conductive wires 10 are surely in contact with each other. To do.

The conductive wire 10 is made of a material used for a general conductive wire. Examples of the material constituting the conductive wire 10 include copper or a copper alloy. Further, the conductive wire 10 may be formed by twisting a copper wire around the outer circumference of a core wire made of fibers, for example.

The conductive wire 10 is not limited to the above as long as it is made of a material that is relatively thicker than the conductive fiber 20 and can carry a large amount of current. For example, as the conductive wire 10, a copper wire or the like having a structure in which a conductive material is electrically plated and a non-conductive material having a conductive plating can be used. Further, the conductive wire 10 does not need to have elasticity by itself.

As shown in FIG. 2, the conductive fibers 20 connect corrugations adjacent to each other in a predetermined direction X of the conductive wire 10. Specifically, the conductive fibers 20 are woven on both sides of the conductive wire 10 in the Y direction to connect the waveforms of the conductive wires 10 to each other to hold the conductive wires 10. However, the conductive fibers 20 may be woven so that stitches are formed in the range in the Y direction in which the conductive wires 10 are arranged. The portion where the conductive fiber 20 is knitted on both sides of the conductive wire 10 in the Y direction constitutes a part of the conductive knitted fabric 30 described later. Curly is formed on the conductive fiber 20. Therefore, the conductive fiber 20 expands and contracts in the longitudinal direction thereof.

The conductive fiber 20 is composed of a core wire and a conductive layer formed on the surface of the core wire. The core wire is composed of, for example, synthetic fibers, natural fibers, and mixed fibers of synthetic fibers and natural fibers.

The conductive layer is formed by, for example, plating (electroless or electrolyzing) the surface of the core wire or wrapping a foil. As the material constituting the conductive layer, materials having high conductivity such as gold, silver, copper, aluminum, tin, nickel copper, and alloys thereof are preferable.
Further, the conductive layer can also be formed by spirally winding a conductive wire having a diameter smaller than that of the core wire.

(knitting)
The knitted fabric 30 is provided on both sides of the conductive wire 10 in the direction Y orthogonal to the predetermined direction X, and holds the conductive wire 10. However, the knitting 30 is not limited to being provided only on both sides of the conductive wire 10 in the Y direction, and the knitting 30 is arranged not only on both sides of the conducting wire 10 in the Y direction but also in the region where the conducting wire 10 is arranged. It may be configured.

The knitted fabric 30 is formed by weaving conductive fibers 20 and is connected to the conductive wire 10. Hereinafter, the knitted fabric knitted with the conductive fibers 20 is referred to as the conductive knitted fabric 30. The conductive fibers 20 constituting the conductive knitted fabric 30 are woven so as to connect the waveforms of the conductive wires 10 to each other in the X direction on both sides of the direction Y.

The method of knitting the conductive knitted fabric 30 can be formed by vertically knitting or weft-knitting the conductive fibers 20, and is not particularly limited. However, when the conductive knitted fabric 30 is constructed by vertically knitting the conductive fibers 20, the conductivity can be made higher than that when the conductive knitted fabric 20 is constructed by weft knitting. That is, when the conductive knitted fabric 30 is knitted by warping the conductive fibers 20 and the plurality of loops are knitted so as to extend the electric wire 1, that is, in the X direction, the conductive knitted fabric 30 is weft-knitted and has a plurality of loops. The conductivity can be made higher than the method in which the loop extends the electric wire 1, that is, the case where the loop is knitted so as to be continuous in the X direction.

Further, when the conductive fiber 20 is vertically knitted to form an electric wire, it can be configured more efficiently than when the conductive fiber is weftly knitted, and the cost can be suppressed. .. Examples of the warp knitting include tricot knitting and Russell knitting.

The conductive knitted fabric 30 has a function of restraining the movement of the conductive wire 10 in the predetermined direction X while allowing the conductive wire 10 to extend in the predetermined direction X, and the conductive wire 10 is in the predetermined direction X. It prevents it from stretching significantly. The conductive knitted fabric 30 is not limited to being provided on both sides of the conductive wire 10 in the direction Y orthogonal to the predetermined direction X, and is provided on both sides of the conductive wire 10 in the Y direction, and the conductive wire 10 is arranged. It can also be provided in the range.

In the electric wire 1A having the above configuration, since the plurality of conductive wires 10 form a waveform and extend in the predetermined direction X, when the electric wire 1A is pulled in the predetermined direction X, the interval between the waveforms is widened in the predetermined direction X. Since the conductive fibers 20 connecting the waveforms of the conductive wires 10 have crimps, they expand and contract freely in the longitudinal direction thereof. Therefore, when a tensile force in the predetermined direction X is applied to the electric wire 1A, the electric wire 1A extends in the predetermined direction. Then, when the tensile force applied to the electric wire 1A is released, the electric wire 1A returns to the original length.

On the other hand, since the electric wire 1A is configured by arranging a plurality of conductive wires 10 forming a waveform and extending in a predetermined direction X in parallel, when the electric wire 1A is pulled in the Y direction, the waveform is deformed in the Y direction. The electric wire 1A extends in the Y direction. Then, when the tensile force in the Y direction applied to the electric wire 1A is released, the dimensions of the electric wire 1A in the Y direction are restored.

When the conductive wire 10 forming the waveform extends in the predetermined direction X, the distance between the waveforms increases, so that the resistance in the predetermined direction X increases. Further, when the conductive wire 10 forming the waveform is stretched in the Y direction, it is deformed so that the interval between the waveforms is widened, and the resistance in the Y direction increases with the deformation. However, in this electric wire 1A, the waveform of the conductive wire 10 is connected by the conductive fibers 20. Therefore, since the conductive fibers 20 pass a current between adjacent waveforms of the conductive wires 10, even when the electric wire 1A is stretched in the predetermined direction X or in the Y direction, the resistance value in the predetermined direction X and the resistance value in the Y direction Extreme increases in resistance are prevented.

The case where the electric wire 1 is composed of the conductive knitted fabric 30 made of the conductive wire 10 and the conductive fiber 20 has been described above as an example. However, as shown in FIG. 3, the electric wire 1 may be configured by knitting the auxiliary conductive wire 15 in addition to the conductive wire 10 and the conductive knitted fabric 30.

(Auxiliary conductive wire)
As shown in FIG. 3, the auxiliary conductive wire 15 extends in a predetermined direction X. The auxiliary conductive wire 15 has a waveform that oscillates in the direction Y orthogonal to the predetermined direction X. The amplitude of the auxiliary conductive wire 15 in the Y direction is larger than the amplitude of the conductive wire 10. Therefore, the auxiliary conductive wire 15 connects the two conductive wires 10 to each other. The wavelength of the waveform formed by the auxiliary conductive wire 15 may be formed longer or shorter than the wavelength of the waveform formed by the conductive wire 10, if necessary. Further, the wavelength of the waveform formed by the auxiliary conductive wire 15 and the wavelength of the waveform formed by the conductive wire 10 can be formed to be the same.

The auxiliary conductive wire 15 reduces the resistance value generated when a current is passed through the electric wire 1B as compared with the case where the electric wire 1A is composed of the two conductive wires 10.

When the auxiliary conductive wire 15 is provided to form the electric wire 1B, the conductive fiber 20 not only connects the waveforms of the conductive wires 10 to each other, but also connects the waveform of the conductive wire 10 and the waveform of the auxiliary conductive wire 15. Further, if necessary, the conductive fibers 20 connect the waveforms of the auxiliary conductive wires 15 to each other.

Further, the conductive knitted fabric 30 not only connects the conductive fibers 20 constituting the conductive knitted fabric 30 to the conductive wire 10, but also connects the conductive fibers 20 constituting the conductive knitted fabric 30 to the auxiliary conductive wire 15. The electric wire 1 is formed by connecting the wires.

[Electric wire with 3 or more conductive wires]
The case where the number of the conductive wires 10 constituting the electric wire 1 is two has been described above as an example. However, the electric wire 1 can also be configured by using three or more conductive wires 10. FIG. 4 shows a case where the electric wire 1C is configured by using the four conductive wires 10. The electric wire 1C composed of three or more conductive wires 10 differs from the electric wires 1A and 1B described with reference to FIGS. 1 to 3 only in the number of the conductive wires 10, and the basic configuration is as follows. , The same is true. Therefore, regarding the electric wire 1C composed of three or more conductive wires 10, a configuration different from that of the electric wire 1 described with reference to FIGS. 1 to 3 will be described in detail, and the same configuration will be described in each drawing. The same reference numerals as those used in FIGS. 1 to 3 will be briefly described with reference to the drawings.

The electric wire 1C shown in FIG. 4 is composed of four conductive wires 10, conductive fibers 20, and a conductive knitted fabric 30. Even when the electric wire 1C is formed by using the four conductive wires 10, as shown in FIG. 4, the conductive wires 10 are structurally arranged in parallel and are configured to extend in a predetermined direction X. Further, the plurality of conductive wires 10 each have a waveform that oscillates in a direction Y orthogonal to a predetermined direction X, and adjacent conductive wires 10 intersect with each other. As for the electric wire 1C, the vertices of the waveform of the conductive wire may be brought into contact with each other.

As shown in FIG. 4, the conductive fibers 20 connect corrugations adjacent to each other in a predetermined direction X of the conductive wire 10. Further, crimps are formed on the conductive fibers 20.

The conductive knitted fabric 30 is provided on both sides of the conductive wire 10 in the direction Y orthogonal to the predetermined direction X. In this conductive knitted fabric 30, conductive fibers 20 are woven and connected to the conductive wire 10. The method of knitting the conductive knitted fabric 30 is not particularly limited, but it is preferable to knit by vertical knitting.

The electric wire 1 having three or more conductive wires 10 can also be configured by weaving an auxiliary conductive wire 15. FIG. 5 shows an example of the electric wire 1D formed by weaving the auxiliary conductive wire 15.

The electric wire 1D shown in FIG. 5 has one auxiliary conductive wire 15. The auxiliary conductive wire 15 forms a waveform that oscillates in the direction Y orthogonal to the predetermined direction X and extends in the predetermined direction X. The amplitude of the auxiliary conductive wire 15 is formed to be larger than the amplitude of the four conductive wires 10, and is connected to the four conductive wires 10. The wavelength of the waveform formed by the auxiliary conductive wire 15 can be formed longer or shorter than the wavelength of the waveform formed by the conductive wire 10, if necessary. Further, the wavelength of the waveform formed by the auxiliary conductive wire 15 and the wavelength of the waveform formed by the conductive wire 10 can be formed to be the same.

The electric wire 1E shown in FIG. 6 is formed by knitting two auxiliary conductive wires 15. One of the two auxiliary conductive wires 15 is connected to the two conductive wires 10 located on the upper side of FIG. On the other hand, the other auxiliary conductive wire 15 connects two conductive wires 10 located on the lower side of FIG.

The wavelengths of the waveforms formed by the two auxiliary conductive wires 15 can be formed to have the same length or different lengths. Further, the wavelength of the waveform formed by the auxiliary conductive wire 15 may be formed longer than the wavelength of the waveform formed by the conductive wire 10, may be formed to have the same length, or may be formed to be shorter, if necessary. it can.

Three or more auxiliary conductive wires may be provided. For example, when three auxiliary conductive wires are provided, one auxiliary conductive wire 15 is provided in the same form as the electric wire 1D shown in FIG. 5, and is arranged so as to connect the four conductive wires 10. The other two auxiliary conductive wires 15 are provided in the same form as the electric wire 1E shown in FIG. 6, and the two conductive wires 10 are arranged so as to be connected to each other.

When three or more conductive wires 10 are provided to form the electric wire 1, as shown in FIG. 7, the conductive wires 10 may be arranged so that the phases of the conductive wires 10 are shifted in a predetermined direction X.

The electric wire 1F shown in FIG. 7 is composed of four conductive wires 10. The four conductive wires are configured by arranging a set of conductive wires 10 in which the two conductive wires 10 are structurally arranged in parallel so as to be displaced in a predetermined direction X. In the electric wire 1F having the structure shown in FIG. 7, one set of conductive wires 10 can function as an auxiliary conductive wire 15 of the other set of conductive wires 10. Further, the size of the electric wire 1F in the Y direction can be made smaller than that of the electric wire 1 formed by arranging four conductive wires 10 in parallel.

[Production method]
The electric wire 1 having the above configuration is manufactured as follows.

The conductive fibers 20 are woven to form the conductive knitted fabric 30 having a constant width in the Y direction. The knitting method is not particularly limited. Further, a plurality of conductive wires 10 are woven into a waveform. The waveforms of the conductive wires 10 are connected by the conductive fibers 20 constituting the conductive knitted fabric 30. Further, the plurality of conductive wires 10 are woven so as to be parallel to each other. At that time, the adjacent conductive wires 10 are woven so as to be connected by intersecting or contacting each other at the corrugated position.

When the electric wire 10 is mass-produced, it can be manufactured at a low cost, so that it is preferable to form the conductive fiber 20 by warp knitting. Further, when a large number of electric wires 1 are manufactured, as shown in FIG. 8, a group of electric wires 1 is formed by arranging a plurality of electric wires 1 in parallel. After that, the conductive knitted fabric 30 is separated along the predetermined direction X at a position between the conductive wires 10. The method of cutting is not particularly limited, and for example, the conductive knitted fabric 30 is cut with a cutting tool. Further, the electric wire may be separated by pulling out the conductive fibers 20 of the conductive knitted fabric 30 constituting the electric wire 10 from the fabric. Further, the electric wires 10 may be separated from each other by knitting the electric wires 10 so as to connect them with water-soluble fibers to form a group of electric wires 10 and immersing the group of electric wires 10 in water to dissolve the water-soluble fibers.

[Form in which a knitted fabric woven with non-conductive fibers is further provided]

In addition to the conductive knitted fabric 30 and the conductive wire 10, the electric wire may be configured by providing the non-conductive knitted fabric 50 in which the non-conductive fibers 40 are woven. The electric wire 2 composed of the non-conductive knit 50, the conductive knit 30, and the conductive wire 10 will be described with reference to FIGS. 9 to 12.

The electric wire 2A shown in FIG. 9 shows a first type electric wire configured by providing the non-conductive knitted fabric 50. The electric wire 2A is composed of a non-conductive knit 50 in which non-conductive fibers 40 are woven, a conductive knit 30 in which conductive fibers 20 are woven, and a conductive wire 10.

The non-conductive fibers 40 constituting the non-conductive knitted fabric 50 are made of non-conductive fibers such as polyester, nylon, polyurethane and water-soluble fibers. The non-conductive knitted fabric 50 is formed by knitting such non-conductive fibers 40. The method of knitting the non-conductive fibers 40 is not particularly limited, and is knitted by, for example, a knitting method such as warp knitting or weft knitting.

The conductive knitted fabric 30 is formed by laminating and knitting conductive fibers 20 on one surface side of the non-conductive knitted fabric 50. Specifically, the conductive knitted fabric 30 is woven so as to form a pair of strips extending in the X direction at regular intervals in the Y direction of the non-conductive knitted fabric 50.

The conductive fibers 20 constituting the conductive knitted fabric 30 have the same structure as the conductive fibers 20 used for the electric wire 1 described with reference to FIG. 2, for example. Further, the method of knitting the conductive fibers 20 is the same as that of the conductive knitted fabric 30 constituting the electric wire 1 described with reference to FIG.

The conductive wire 10 is woven so as to overlap the surface of the conductive knitted fabric 30. Specifically, the conductive wire 10 is woven between a pair of conductive knits 30 arranged at regular intervals in the Y direction in contact with one conductive knit 30 and the other conductive knit 30. ing. The woven conductive wire 10 is formed so as to oscillate in the Y direction and extend in the X direction to form a corrugated shape. The oscillating top of the conductive wire 10, that is, both sides in the Y direction, is held by the conductive fibers 20 constituting the conductive knitted fabric 30.

In the electric wire 2A shown in FIG. 9, three conductive wires 10 are used. The three conductive wires 10 intersect with each other and are in contact with each other at the intersecting portions.

The electric wire 2A shown in FIG. 9 is configured by superimposing the non-conductive knitted fabric 50, the conductive knitted fabric 30, and the conductive wire 10 in the thickness direction of the electric wire 2A. That is, in the electric wire 2A shown in FIG. 9, the conductive fibers 20 are woven on one side of the non-conductive knit 50, so that the conductive knit 30 is superposed on the non-conductive knit 50 and the conductive wire 10 is formed. It is constructed by being woven into the surface of the conductive knitted fabric 30 so as to be overlapped with each other. However, although not shown in the drawings, the electric wire 2A can also be configured by weaving the non-conductive knitting 50, the conductive knitting 30 and the conductive wire in a plane.

Specifically, the electric wires 2A are arranged inside a pair of parallel strip-shaped non-conductive knits 50 and a pair of non-conductive knits 50, and are arranged inside a pair of parallel strip-shaped conductive knits 20 and a pair. It is composed of a conductive wire 10 having a corrugated shape that connects the conductive knits 20 between the conductive knits 20.

Next, the second type electric wire 2B provided with the non-conductive knitted fabric 50 will be described with reference to FIG.

Similar to the first type electric wire 1, the second type electric wire 2B includes a non-conductive knit 50 in which non-conductive fibers 40 are woven, a conductive knit 30 in which conductive fibers 20 are woven, and a conductive wire. It is composed of 10.

The non-conductive fiber 40 is the same as the non-conductive fiber 40 used in the first type electric wire 1. Further, the structure of the non-conductive knit 50 is the same as that of the non-conductive knit 50 constituting the first type electric wire 1.

The conductive knitted fabric 30 is superposed on one side of the non-conductive knitted fabric 50 and woven into the non-conductive knitted fabric 50. The conductive knitted fabric 30 has a constant width in the Y direction and forms a single strip extending in the X direction. The knitting method of the conductive knitted fabric 30 is the same as the knitting method of the conductive knitted fabric 30 constituting the electric wire 1 described with reference to FIG. Further, the conductive fibers 20 are the same as the conductive fibers 20 of the conductive knitted fabric 30 constituting the electric wire 1 described with reference to FIG.

The conductive wire 10 is woven on the surface of the conductive knitted fabric 30 and is held by the conductive fibers 20 constituting the conductive knitted fabric 30. The conductive wire 10 has a waveform that oscillates in the Y direction and extends in the X direction. The top of the waveform, that is, both ends of the conductive wire 10 in the Y direction are located closer to the center than both ends of the conductive knitted fabric 30 in the Y direction.

Also for the electric wire 2B shown in FIG. 10, three conductive wires 10 are used. The three conductive wires 10 intersect with each other and are in contact with each other at the intersecting portions.

Next, with reference to FIG. 11, the third type electric wire 2C provided with the non-conductive knitted fabric 50 will be described.

The third type electric wire 2C is different from the second type electric wire 2B in the way in which the conductive wire 10 is woven. However, the other configurations of the third type electric wire 2C are the same as the configurations of the second type electric wire 2B. Therefore, for this third type electric wire 2C, only the method of knitting the conductive wire 10 will be described, and the other configurations are the same as the reference numerals given to the respective configurations constituting the second type electric wire 2B in FIG. Reference numerals will be given and the description thereof will be omitted.

A plurality of conductive wires 10 are used. In the example shown in FIG. 11, three conductive wires 10 are used. The three conductive wires 10 are woven into the conductive knit 30 so as to oscillate in the Y direction and extend in the X direction, and are held by the conductive fibers 20 constituting the conductive knit 30. Further, the three conductive wires 10 are woven into the conductive knitted fabric 30 at intervals so as not to come into contact with each other.
