Description

  TECHNICAL FIELD The present invention relates to an electric wire, and more particularly, to an electric wire that can be stretched in both longitudinal and lateral directions.

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

  For example, the stretchable electric wire proposed by Patent Document 1 is used for wiring of robots, wearable electronic devices, and the like. The expandable electric wire is composed of an elastic core part, a conductor part formed of a conductor wire wound and / or braided around the elastic core part, and an elastic resin formed on the outer periphery of the conductor part. 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, the woven fabrics and knitted fabrics have been made conductive.

  Patent Document 2 proposes a conductive woven or knitted fabric. This conductive woven or knitted fabric comprises a plurality of warp yarns arranged along the longitudinal direction, a plurality of weft yarns knitted on the warp yarns, and at least one conductive wire arranged along the longitudinal direction. It is configured by being woven in a planar shape. The conductive wire is knitted into warp yarns and / or weft yarns, and the conductive wire weaving section is constrained integrally with the conductive woven and knitted fabric, and the conductive wire is not knitted into warp yarns and / or weft yarns, And a conductive wire exposure section exposed by a predetermined length. Note that Patent Document 2 also proposes folding the conductive wire into a wavy structure.

  The expandable electric wire proposed by Patent Document 1 expands and contracts only in the longitudinal direction. Further, since the expandable 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 expandable electric wire, the expandable electric wire cannot be directly connected to the fibers constituting the garment, and special processing is required for connecting.

  On the other hand, the conductive woven or knitted fabric proposed in Patent Document 2 is a woven fabric in which a base material is composed of warp yarns extending linearly in the longitudinal direction and weft yarns extending linearly in the transverse direction. Conductive wires are woven into these fabrics. Therefore, the conductive woven / knitted fabric hardly stretches in both the machine direction and the transverse 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 to be used in various industrial fields, and an electric wire that can be extended in both the longitudinal direction and the direction orthogonal to the longitudinal direction. 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 has a knitted fabric in which fibers are knitted, and the conductive wires are held by the fibers, and a plurality of the conductive materials The line has a waveform having an amplitude in a direction orthogonal to the predetermined direction, and the line is extended in the predetermined direction by being connected in the predetermined direction.

  According to this invention, the plurality of conductive wires have a waveform that oscillates in a direction orthogonal to the predetermined direction, and the waveforms are continuous in the predetermined direction to extend in the predetermined direction. When a tensile force is applied, the corrugated space expands in a predetermined direction so that the electric wire can be stretched. 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 stretchability of the knitted fabric is used to freely move the conductive wire in the direction orthogonal to the predetermined direction. It is possible to extend it.

  In the electric wire according to the present invention, the fiber constituting the knitted fabric is a conductive fiber having conductivity, and the conductive fiber has a crimp, and the conductive fiber is the conductive wire. The corrugations adjacent to each other in a predetermined direction are connected to each other.

  According to this invention, since the curled conductive fiber connects the corrugations adjacent to each other in the predetermined direction in the conductive wire, when the tensile force is applied to the electric wire, the expansion of the crimp of the conductive fiber is used. Thus, the electric wire can be extended in either the predetermined direction or the direction orthogonal to the predetermined direction. Further, even when the electric wire is stretched, the conductive fibers connect the adjacent waveforms in the predetermined direction in the conductive wire, so that the resistance value can be prevented from extremely increasing.

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

  According to this invention, since the conductive wires cross each other and are in contact with each other, even if the conductive wires are physically broken 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 further comprises one or two or more auxiliary conductive wires extending in the predetermined direction, and the auxiliary conductive wire has at least a waveform oscillating in a direction orthogonal to the predetermined direction. The two conductive lines are connected to each other.

  According to the present invention, since the auxiliary conductive wire connects the conductive wires to each other, it is possible to reduce the resistance value of the electric wire as compared with the electric wire not provided with the auxiliary conductive wire.

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

  According to this invention, it is possible to prevent the conductive fiber from extremely widening the interval between the corrugations formed by the conductive wires and from deforming the corrugations extremely. Therefore, even if a large tensile force is applied to the electric wire, it is possible to prevent the conductive wire from breaking.

  In addition, in the electric wire according to the present invention, it is preferable that the conductive fiber is warp-knitted. According to the present invention, since the fabric portion is formed by warp-knitting the conductive fibers, it is possible to increase the conductivity as compared with the case where the cloth portion is knitted. In addition, when the electric wire is manufactured by knitting the conductive fiber, the conductive fiber can be manufactured by weft knitting or warp knitting. However, when the electric wire is formed by warp-knitting the conductive fibers as in the present invention, the electric wire can be formed more efficiently and the cost can be suppressed as compared with the case where the conductive fibers are weft-knitted. It will be possible.

Furthermore, the electric wire according to the present invention has a plurality of conductive wires extending in a predetermined direction X, and a knitted fabric in which fibers are knitted, and the fibers hold the conductive wires. Waveforms each having an amplitude in a direction Y orthogonal to the predetermined direction X are arranged such that the phases of the waveforms are shifted in the predetermined direction X, the conductive lines intersect with each other, and the waveforms contact each other. By the fact that the corrugations are respectively linked in the predetermined direction X, they extend in the predetermined direction X, the fibers constituting the knitted fabric are conductive fibers having conductivity, and the plurality of conductive wires are The conductive fiber is woven, and the conductive fiber has a crimp, and the conductive fiber connects the corrugations adjacent to each other in the predetermined direction X of the conductive wire, And

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

  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 fabric 30 in which fibers 20 are knitted and the conductive wires 10 are held by the fibers 20. have. The plurality of conductive lines 10 each have a waveform that oscillates in a direction Y orthogonal to the predetermined direction X, and the waveforms are continuous in the predetermined direction X to extend in the predetermined direction X.

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

(Conductive wire)
As shown in FIGS. 1 and 2, two conductive wires 10 are provided and are arranged in parallel structurally. Each conductive wire 10, a predetermined direction in terms of symbol X in FIGS. 1 and 2 (hereinafter, referred to as. "Predetermined Direction X") extend respectively. Further, each conductive wire 10 has 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 lines 10 are adjacent to each other and are in contact with each other. The conductive lines intersect at a plurality of positions in the X direction.

  The two conductive lines 10 are arranged such that the centers of the amplitudes of the conductive lines 10 are separated by a certain distance. The distance between the centers of the amplitudes of the conductive lines 10 is the same as or shorter than the amplitude of the waveform formed by the conductive lines 10. Further, the phases of the waveforms are displaced in the predetermined direction X. Since the distance between the centers of the amplitudes of the conductive lines 10 and the phase of the waveform of the two conductive lines 10 are configured in this manner, the waveforms of the two conductive lines 10 are crossed by intersecting the two conductive lines 10. Contact. Although not shown in the drawing, the conductive wire 10 may be arranged so that the vertices of the corrugations are in contact with each other.

  Since the conductive wires 10 are in contact with each other as described above, the conductive wires 10 flow into the conductive wires 10 even if the contact shortage between the conductive wires 10 and the conductive fibers 20 partially occurs. The current can be distributed and passed. Further, since the distance between the centers of the amplitudes of the conductive wires 10 (the distance in the Y direction) is the same as or shorter than the amplitude of the waveform formed by the conductive wires 10, 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 forming the conductive wire 10 include copper and copper alloys. The conductive wire 10 may be formed by twisting a copper wire around the outer circumference of a core wire made of fiber.

  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 flow a large amount of current. For example, the conductive wire 10 may have a structure in which a conductive material is conductively plated on a copper wire or the like, or a structure in which a non-conductive material is conductively plated. Further, the conductive wire 10 does not need to have elasticity itself.

  As shown in FIG. 2, the conductive fiber 20 connects the corrugations adjacent to each other in the predetermined direction X of the conductive wire 10. Specifically, the conductive fiber 20 holds the conductive wire 10 by knitting on both sides of the conductive wire 10 in the Y direction to connect the corrugations of the conductive wire 10 together. However, the conductive fibers 20 may be woven so that the stitches are formed in the Y-direction range in which the conductive wires 10 are arranged. The portion in which 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. The conductive fibers 20 are crimped. Therefore, the conductive fiber 20 expands and contracts in the longitudinal direction.

  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 electrolytic) or winding a foil on the surface of the core wire. As a material for forming the conductive layer, materials having high conductivity such as gold, silver, copper, aluminum, tin, nickel copper, and alloys thereof are preferable.
The conductive layer can also be formed by spirally winding a wire having a diameter smaller than that of the core wire and having conductivity.

(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, knitting 30 is not limited to providing only the both sides in the Y-direction of the conductive wire 10, knit 30 are also arranged in a region where conductor 10 is arranged in addition to both sides in the Y direction of the conductive wire 10 It may be configured as follows.

  The knitted fabric 30 is formed by knitting the conductive fiber 20 and is connected to the conductive wire 10. Hereinafter, a knitted fabric knitted with the conductive fibers 20 is referred to as a conductive knitted fabric 30. The conductive fibers 20 forming the conductive knit 30 are knitted so as to connect the respective corrugations of the conductive wire 10 in the X direction on both sides in the direction Y.

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

  Further, when the conductive fiber 20 is warp-knitted to form an electric wire, the electric wire can be efficiently constructed and the cost can be suppressed as compared with the case where the conductive fiber is weft-knitted. . Examples of the warp knitting include tricot knitting and Russell knitting.

  The conductive knit 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. It prevents it from expanding greatly. 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 a range.

  In the electric wire 1A having the above configuration, the plurality of conductive wires 10 form a waveform and extend in the predetermined direction X. Therefore, when the electric wire 1A is pulled in the predetermined direction X, the interval between the waveforms expands in the predetermined direction X. Since the conductive fiber 20 connecting the corrugations of the conductive wire 10 has a crimp, it freely expands and contracts in its longitudinal direction. 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 that form a waveform and extend in the predetermined direction X in parallel, when the electric wire 1A is pulled in the Y direction, the waveform deforms in the Y direction, The electric wire 1A extends in the Y direction. Then, when the tensile force applied to the electric wire 1A in the Y direction is released, the dimension of the electric wire 1A in the Y direction returns to the original size.

  When the conductive wire 10 having a waveform extends in the predetermined direction X, the interval between the waveforms widens, so that the resistance in the predetermined direction X increases. Further, when the corrugated conductive wire 10 extends in the Y direction, the corrugated conductive lines 10 are deformed so that the interval between the corrugations 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 fiber 20. Therefore, since the conductive fiber 20 causes a current to flow between adjacent waveforms of the conductive wire 10, even when the electric wire 1A extends in the predetermined direction X or in the Y direction, the resistance value in the predetermined direction X and the Y direction can be reduced. Extreme increases in resistance are prevented.

  The case where the electric wire 1 is composed of the conductive knitted fabric 30 including 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 weaving an auxiliary conductive wire 15 in addition to the conductive wire 10 and the conductive knit 30.

(Auxiliary conductive wire)
The auxiliary conductive line 15 extends in the predetermined direction X, as shown in FIG. The auxiliary conductive line 15 has a waveform oscillating in a 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 line 15 connects the two conductive lines 10 to each other. The wavelength of the waveform formed by the auxiliary conductive line 15 can be longer or shorter than the wavelength of the waveform formed by the conductive line 10 as required. Further, the wavelength of the waveform formed by the auxiliary conductive line 15 and the wavelength of the waveform formed by the conductive line 10 can be formed to be the same.

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

  When the electric wire 1B is configured by providing the auxiliary conductive wire 15, the conductive fiber 20 not only connects the waveforms of the conductive wire 10 but also connects the waveform of the conductive wire 10 and the waveform of the auxiliary conductive wire 15. In addition, the conductive fibers 20 connect the corrugations of the auxiliary conductive wires 15 with each other, if necessary.

  In addition, the conductive knit 30 not only connects the conductive fibers 20 forming the conductive knit 30 to the conductive wire 10, but also connects the conductive fibers 20 forming the conductive knit 30 to the auxiliary conductive wire 15. The electric wire 1 is constructed by connecting the wires.

[Electric wire having three or more conductive wires]
The case where the number of the conductive wires 10 forming 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 four conductive wires 10. The electric wire 1C configured by three or more conductive wires 10 is different from the electric wires 1A and 1B described with reference to FIGS. , The same. Therefore, regarding the electric wire 1C composed of three or more conductive wires 10, a configuration different from 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 includes four conductive wires 10, conductive fibers 20, and a conductive knit 30. Even when the electric wire 1C is configured by using the four conductive wires 10, the conductive wires 10 are structurally arranged in parallel and extend in the predetermined direction X, as shown in FIG. In addition, the plurality of conductive lines 10 have a waveform that oscillates in a direction Y orthogonal to the predetermined direction X, and adjacent conductive lines 10 intersect with each other. In this electric wire 1C as well, the vertices of the waveform of the conductive wire may be in contact with each other.

  As shown in FIG. 4, the conductive fiber 20 connects the corrugations adjacent to each other in the predetermined direction X of the conductive wire 10. Further, the conductive fibers 20 are crimped.

  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. The conductive knit 30 is knitted with the conductive fibers 20 and connected to the conductive wire 10. The method for knitting the conductive knitted fabric 30 is not particularly limited, but it is preferable to knit by warp knitting.

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

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

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

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

  It is also possible to provide three or more auxiliary conductive lines. For example, when providing three auxiliary conductive wires, 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 are arranged so that the two conductive wires 10 are connected together.

  When the electric wire 1 is formed by providing three or more conductive wires 10, as shown in FIG. 7, the conductive wires 10 may be arranged such that their phases are shifted in the 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 two conductive wires 10 are structurally arranged in parallel and displaced in the predetermined direction X. In the electric wire 1F having the structure shown in FIG. 7, one set of the conductive lines 10 can function as the auxiliary conductive line 15 of the other set of the conductive lines 10. Further, the electric wire 1F can have a smaller dimension in the Y direction than the electric wire 1 configured by arranging four conductive wires 10 in parallel.

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

  The conductive fiber 20 is knitted to form a conductive knit 30 having a certain width in the Y direction. The knitting method is not particularly limited. In addition, a plurality of conductive wires 10 are woven in a wave shape. The waveforms of the conductive wires 10 are connected by the conductive fibers 20 forming the conductive knit 30. In addition, the plurality of conductive wires 10 are woven so as to be parallel to each other. At that time, the conductive wires 10 adjacent to each other are braided so as to be connected to each other by intersecting or contacting each other at a wavy position.

  When the electric wire 10 is mass-produced, it can be manufactured at low cost, and therefore 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 plurality of electric wires 1 are arranged in parallel to form a group of electric wires 1. Then, the conductive knitted fabric 30 is separated along the predetermined direction X at a position between the conductive wires 10. The method for separating the conductive knitted fabric 30 is not particularly limited, and the conductive knitted fabric 30 is cut with a blade, for example. Alternatively, the electric wire may be separated by pulling out the conductive fiber 20 of the conductive knitted fabric 30 forming the electric wire 10 from the cloth. Further, the electric wires 10 may be woven together so as to be connected by water-soluble fibers to form a group of electric wires 10, and the electric wires 10 may be separated by immersing the group of electric wires 10 in water to melt the water-soluble fibers.

[A mode in which a knitted fabric in which a non-conductive fiber is woven is further provided]
The electric wire 1 including the conductive wire 30 and the conductive wire 10 in which the conductive fiber 20 is knitted has been described above. In addition to the conductive knit 30 and the conductive wire 10, the electric wire can be configured by providing a non-conductive knit 50 in which a non-conductive fiber 40 is knitted. The electric wire 2 including the non-conductive knitted fabric 50, the conductive knitted fabric 30, and the conductive wire 10 will be described with reference to FIGS. 9 to 12.

  The electric wire 2A shown in FIG. 9 is a first type electric wire configured by providing the non-conductive knitted fabric 50. The electric wire 2A includes a non-conductive knitted fabric 50 in which the non-conductive fibers 40 are knitted, a conductive knitted fabric 30 in which the conductive fibers 20 are knitted, and the 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 configured by knitting such non-conductive fibers 40. The method of knitting the non-conductive fiber 40 is not particularly limited, and is knitted by, for example, warp knitting or weft knitting.

  The electrically conductive knitted fabric 30 is configured by overlapping and knitting the electrically conductive fiber 20 on one surface side of the non-conductive knitted fabric 50. Specifically, the conductive knitted fabric 30 is knitted in 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 fiber 20 that constitutes the conductive knitted fabric 30 has, for example, the same configuration as the conductive fiber 20 used for the electric wire 1 described with reference to FIG. 2. Further, the method of knitting the conductive fiber 20 is the same as that of the conductive knitted material 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 knitted by connecting one conductive knitted fabric 30 and the other conductive knitted fabric 30 between a pair of conductive knitted fabrics 30 arranged at regular intervals in the Y direction. ing. The braided conductive wire 10 is formed so as to oscillate in the Y direction and extend in the X direction to form a waveform. Then, the oscillated top portion of the conductive wire 10, that is, both sides in the Y direction are 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 lines 10 intersect each other, and contact each other at the intersecting portions.

  The electric wire 2A shown in FIG. 9 is configured by stacking 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 fiber 20 is knitted on one surface side of the non-conductive knit 50, whereby the conductive knit 30 is superposed on the non-conductive knit 50, and the conductive wire 10 is The conductive knitted fabric 30 is knitted on the surface of the conductive knitted fabric to be superposed on each other. However, the electric wire 2A can also be configured by braiding the non-conductive knitted fabric 50, the conductive knitted fabric 30, and the conductive wire in a plane, although not particularly shown in the drawing.

  Specifically, the electric wire 2A includes a pair of parallel belt-shaped non-conductive knitted fabrics 50, a pair of parallel strip-shaped conductive knitted fabrics 20 arranged inside the pair of non-conductive knitted fabrics 50, and a pair of The conductive wire 10 has a corrugated shape and connects the conductive knitted materials 20 to each other.

  Next, with reference to FIG. 10, the second type electric wire 2B including the non-conductive knitted fabric 50 will be described.

  The second-type electric wire 2B is similar to the first-type electric wire 1 in that the non-conductive knitted fabric 50 in which the non-conductive fiber 40 is knitted, the conductive knitted fabric 30 in which the conductive fiber 20 is knitted, and the 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. The configuration of the non-conductive knitted fabric 50 is also the same as that of the non-conductive knitted fabric 50 that constitutes the first type electric wire 1.

  The conductive knitted fabric 30 is superposed on one surface side of the non-conductive knitted fabric 50 and woven into the non-conductive knitted fabric 50. The conductive knitted fabric 30 has a certain width in the Y direction and a single strip extending in the X direction. The method of knitting the conductive knit 30 is the same as the method of knitting the conductive knit 30 constituting the electric wire 1 described with reference to FIG. 2. The conductive fiber 20 is also the same as the conductive fiber 20 of the conductive knitted fabric 30 that constitutes the electric wire 1 described with reference to FIG. 2.

  The conductive wire 10 is woven on the surface of the conductive knitted fabric 30 and is held by the conductive fibers 20 forming the conductive knitted fabric 30. The conductive line 10 has a waveform oscillating in the Y direction and extending in the X direction. The top of the corrugation, that is, both ends of the conductive wire 10 in the Y direction are located closer to the center side 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 lines 10 intersect each other, and contact each other at the intersecting portions.

  Next, with reference to FIG. 11, a third type electric wire 2C including 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 method of weaving the conductive wire 10. However, the other configurations of the third-type electric wire 2C are similar to those of the second-type electric wire 2B. Therefore, for the third type electric wire 2C, only the method of knitting the conductive wire 10 will be described, and other configurations are the same as the reference numerals given to the respective configurations of the second type electric wire 2B in FIG. The reference numerals are given and the description is omitted.

  A plurality of conductive lines 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 knitted fabric 30 so as to oscillate in the Y direction and extend in the X direction, and are held by the conductive fibers 20 forming the conductive knitted fabric 30. Further, the three conductive wires 10 are knitted in the conductive knitted fabric 30 at intervals so that they do not contact each other.

  Next, with reference to FIG. 12, a fourth type electric wire 2D including the non-conductive knitted fabric 50 and the conductive wire 10 will be described.

  As shown in FIG. 12, the fourth type electric wire 2D is composed of a non-conductive knitted fabric 50 in which non-conductive fibers 40 are knitted, and a plurality of conductive wires 10. In addition, the structure of the non-conductive knitted fabric 50 and the structure of the non-conductive fiber 40 constituting the non-conductive knitted fabric 50 are the same as those of the non-conductive knitted fabric 50 used for the electric wires 2C of the first to third types. The configuration is the same as that of the non-conductive fiber 40. Therefore, the description of the configuration of the non-conductive knitted fabric 50 and the configuration of the non-conductive fiber 40 is omitted here.

  A plurality of conductive wires 10 are used, and each conductive wire 10 is woven into the conductive knitted fabric 30 so as to oscillate in the Y direction and extend in the X direction. In the example of the fourth type electric wire 2D shown in FIG. 12, three conductive wires 10 are used. The three conductive lines 10 are arranged at intervals so that they do not contact each other.

  In the electric wire 2D of the fourth type, since the conductive wires 10 are directly knitted in the non-conductive knitted fabric 50 made of the non-conductive fibers 40 which are spaced apart from each other and have no conductivity, the conductive wires 10 are mutually connected. Insulated. Therefore, the electric wire 2D of the fourth type can be used as a wiring of another system by flowing different electric signals to the conductive wires 10 and the like.

  The electric wires 1 and 2 described above can be used, for example, as various cables used in OA equipment and industrial machines. Examples of the OA device include a USB (Universal Serial Bus). In addition, when the conductive knit 30 of the electric wire 1 is formed in a rectangular shape and the conductive wire 10, the conductive fiber 20 and the auxiliary conductive wire 15 are provided at the opposite side edge portions of the conductive knit 30, this structure is obtained. It can be used as a cloth heater and an electrode of the cloth heater.
