Description

  The present invention relates to a current-carrying member for passing a current for the purpose of supplying a current to an electric / electronic device.

  A lead wire is widely used as this kind of electric conductor. The lead wire is a conductor composed of a single wire such as copper or a stranded wire of a plurality of strands and is covered with a non-conductive resin coating material, and is externally a “wire”. In addition, there is an advantage that it can be bent relatively freely. Further, the conductor is electrically insulated from the surroundings by the covering material, and if the conductor is exposed by peeling the resin covering material, it can be electrically connected by soldering, crimping or the like.

  However, even if the conductor is a single wire or a twisted wire of a plurality of strands, most of them have a substantially circular cross section. As described above, since it does not fall within the category of “line”, the surface area is small, and therefore the heat dissipation of resistance heat generated during energization is low. And if it is going to send a large electric current, in order to enlarge the cross-sectional area of a conductor, it is necessary to enlarge a diameter, and while it becomes bulky, there exists a problem that a flexibility reduces. Moreover, if a lead wire sees this, it will be immediately understood that it is a lead wire, and its design is poor. Moreover, a person feels uncomfortable when he / she touches a lead wire, either in the sense that it is recognized as a lead wire through which an electric current passes, or in a sense that the resin coating material is unfamiliar to human skin.

  By the way, Patent Documents 1 to 5 describe a mixed yarn formed by twisting a conductive metal wire to a normal spinnable fiber, and a conductive fabric formed by weaving the mixed yarn. The conductive fabrics of Patent Documents 1 to 4 are intended to shield electromagnetic waves, and therefore do not pass current because they only need to be at ground potential. Therefore, since there is no problem of a short circuit or an electric shock, it is not necessary to cover the conductive fabric with a non-conductive material. Actually, this conductive fabric exhibits a greater electromagnetic shielding performance by making the proportion of the area of the conductive metal wire exposed on the surface as large as possible, and the conductive metal wire is not covered with a non-conductive material. Moreover, although the textile fabric and knitted fabric of patent document 5 are for sending an electric current, they are not covered with the nonelectroconductive material. Patent Document 2 describes that a conductive fabric is sandwiched between two thin organic synthetic resin sheets and bonded or thermocompression bonded into a sheet shape. Since the organic synthetic resin sheet is intended to prevent rust of the conductive metal wire, it is considered to be watertight and poor in air permeability. Further, since it is in the form of a sheet, it is poor in flexibility, and when sewing is performed, there is a risk of tearing from the sewn part.

JP 2006-124900 A JP 2011-179162 A Japanese Patent Laid-Open No. 10-280208 JP 2007-277745 A JP 2011-74512 A

  Therefore, the present invention is flat, has high design, is not recognized as a lead wire, is familiar to human skin, has high heat dissipation of resistance heat generated when energized, and has an insulating function from the surroundings. It is an object of the present invention to provide a flat insulation coated conductive body that can be flexibly and freely deformed and can be used after being cut or sewn.

  In order to solve the above-described problems, the flat insulation coated conductive body of the present invention includes a conductive thread in which a linear metal is spirally wound in one direction around a core thread, and a strip metal is spirally wound around the core thread. Woven at least one conductive yarn selected from the group consisting of conductive yarn formed by forming a conductive film on the surface of the yarn, and conductive yarn obtained by spinning a material containing a conductive material. In order to electrically insulate the surroundings by covering the surface of one side or both sides of the conductive base material with a conductive base material for energization and a non-conductive yarn made of thermoplastic resin fibers. A joined non-conductive substrate was provided.

  According to the flat insulation coated conductive body of the present invention, it is flat, has high design, is not recognized as a lead wire, is familiar to human skin, and has high heat dissipation of resistance heat generated during energization. Also, it has an insulating function with respect to the surroundings, can be deformed flexibly and freely, and has an excellent effect that it can be used after being cut or sewn.

A part of flat type insulation coating electrically-conductive body of Example 4 is shown, (a) is a perspective view, (b) is sectional drawing. FIG. 2A is a plan view of a part of a conductive yarn, and FIG. 2B is a perspective view of a part of a conductive base material of the same flat type insulating covering conductive body. A part of flat type insulation coating electrically-conductive body of Example 5 is shown, (a) is a perspective view, (b) is sectional drawing. It is sectional drawing which shows the cross section of a strip | belt-shaped metal as contrasted with the virtual line cross section of a linear metal. The manufacturing process of a strip | belt-shaped metal is shown, (a) is a figure which cuts a foil-shaped metal into a strip | belt shape, (b) is a figure which compresses a metal wire flatly.

(1) Conductive base material The conductive base material is for energization, and is a conductive thread in which a linear metal is spirally wound in one direction around a core thread, and a strip metal is spiraled around the core thread. Weaving at least one conductive yarn selected from the group consisting of a conductive yarn wound, a conductive yarn having a conductive coating formed on the surface of the yarn, and a conductive yarn obtained by spinning a material containing a conductive material. It shall be (woven fabric).

  Although it does not specifically limit as a structure | tissue of an electroconductive base material (woven fabric), A plain weave, twill, etc. can be illustrated. Plain weaving is preferable in that the distance between the conductive yarns can be increased and the heat dissipation effect is high. The yarn density of the conductive substrate (woven fabric) varies depending on the thickness of the yarn and is not particularly limited, but is preferably 2 to 50 per 2.54 cm (1 inch). If the yarn density is less than two, it is difficult to maintain the shape as a woven fabric, and there is a risk of poor contact between the conductive yarns. On the other hand, if the number exceeds 50, the conductive yarns become dense and the heat dissipation effect is reduced. The yarn density of the warp and the yarn density of the weft may be the same or different. The conductive yarn used for the warp and the conductive yarn used for the weft may be the same or different. By making the conductive yarns used for the warp and the weft different, the characteristics can be changed depending on the direction of the woven fabric.

(1-1) Conductive yarn in which a linear metal is spirally wound in one direction around a core yarn This conductive yarn can have stretchability and is excellent in woven property. Further, depending on the diameter of the linear metal, a low resistance conductive yarn can be formed.

  The core yarn may be a spun yarn or a filament yarn. Although it does not specifically limit as a fiber material of a thread | yarn, A synthetic fiber, a natural fiber, glass fiber, a rock fiber etc. can be illustrated. Examples of raw materials for synthetic fibers include thermoplastic resins such as polyester, nylon, acrylic, and polyurethane, rayon, cupra, and acetate. Examples of natural fibers include cotton, hemp, linen, wool, silk, cashmere and the like. Although it does not specifically limit as linear density of a thread | yarn, 20-300 denier can be illustrated.

  Although it does not specifically limit as a metal material of a linear metal, Copper, aluminum, silver, nickel etc. can be illustrated. Copper and aluminum are preferable because of high conductivity and flexibility. Although the thickness of a linear metal is not specifically limited, 30-150 micrometers is preferable. If it is less than 30 μm, it is difficult to flow a large current, and if it exceeds 150 μm, it is difficult to perform processing such as cutting.

(1-2) Conductive thread formed by spirally winding a band-shaped metal around a core thread This conductive thread can have stretchability and is excellent in woven property. In addition, the linear metal easily penetrates through the gap of the non-conductive base material when folded, but the band-like metal has a width, so it is difficult to penetrate through the gap of the non-conductive base material when folded. Insulation performance can be maintained. In addition, the band-shaped metal can suppress the thickness and can maintain flexibility as a woven fabric. Further, as shown in FIG. 8, the band-like metal 5 has higher conductivity by a smaller amount of the gap 7 than the plurality of linear metals 6 having the same exclusive sectional area, and can cope with a large current. . Further, since the band-shaped metal is less likely to bite into the core yarn than the linear metal, when a stretch material is used for the fiber of the core yarn, a stretchable conductive yarn can be formed without biting into the core yarn.

  The core yarn may be a spun yarn or a filament yarn. Although it does not specifically limit as a fiber material of a thread | yarn, What was illustrated by said (1-1) can be illustrated similarly. Although it does not specifically limit as linear density of a thread | yarn, 20-300 denier can be illustrated.

  Although the aspect of a strip | belt-shaped metal is not specifically limited, as shown to Fig.9 (a), the strip | belt-shaped metal 5 which cut | disconnected the metal foil or metal foil 8 which bonded resin films, such as a polyester film, in strip shape, or FIG. As shown in b), for example, a band-shaped metal 5 obtained by compressing a metal wire 9 into a flat shape can be exemplified. Although it does not specifically limit as a metal material of a strip | belt-shaped metal, Copper, aluminum, silver, nickel etc. can be illustrated. Copper and aluminum are preferable because of high conductivity and flexibility. Although the thickness of a strip | belt-shaped metal is not specifically limited, 5-100 micrometers can be illustrated. Although the width | variety of a strip | belt-shaped metal is not specifically limited, 0.1-2 mm can be illustrated.

(1-3) The conductive yarn obtained by forming a conductive film on the surface of the yarn may be a spun yarn or a filament yarn. Although it does not specifically limit as a fiber material of a thread | yarn, What was illustrated by said (1-1) can be illustrated similarly. Although it does not specifically limit as linear density of a thread | yarn, 20-300 denier can be illustrated.

  Although it does not specifically limit as a material of a conductive film, A metal, a metal oxide, carbon etc. can be illustrated. The method for coating the conductive film is not particularly limited, and examples thereof include plating, vapor deposition, and powder coating.

(1-4) Conductive yarn formed by spinning a yarn raw material containing a conductive material The conductive material is not particularly limited, and examples thereof include metal powder and carbon powder. The yarn raw material may be a synthetic fiber raw material, and examples thereof include thermoplastic resins such as polyester, nylon, acrylic, and polyurethane, rayon, cupra, and acetate. Although it does not specifically limit as linear density of a thread | yarn, 20-300 denier can be illustrated. The yarn to be spun may be a spun yarn or a filament yarn.

(2) Non-conductive base material The non-conductive base material is a thermoplastic resin that is joined to cover one surface or both surfaces of the conductive base material to electrically insulate the surface from the surrounding surface. A non-conductive yarn made of fibers is woven (woven fabric). Regarding the degree of non-conductivity, the surface resistance of the non-conductive substrate is preferably 5000 times or more, more preferably 10,000 times or more with respect to the surface resistance of the non-conductive substrate.

  Although it does not specifically limit as a structure | tissue of a nonelectroconductive base material (woven fabric), A plain weave, twill, etc. can be illustrated. The yarn density of the non-conductive substrate (woven fabric) varies depending on the thickness of the yarn and is not particularly limited, but is preferably 30 to 100 per 2.54 cm (1 inch). If the yarn density is less than 30, the gap may be formed in the woven fabric, which may reduce the insulation. On the other hand, when the number exceeds 100, weaving becomes difficult. The yarn density of the warp and the yarn density of the weft may be the same or different. The non-conductive yarn used for the warp and the non-conductive yarn used for the weft may be the same or different.

(2-1) Non-conductive yarn By using a non-conductive yarn made of thermoplastic resin fiber, the non-conductive base material formed by weaving it can be partially melted with a soldering iron and peeled off. It becomes easy to solder to the conductive substrate exposed in the same part, and the usability as an electric current body used for the purpose of supplying electric current to the electric / electronic device is improved.

  Although it does not specifically limit as a raw material of a thermoplastic resin fiber, Polyester, nylon, an acryl, a polyurethane etc. can be illustrated. The linear density of the non-conductive yarn is not particularly limited, but is preferably 20 to 900 denier. If it is less than 20 denier, the strength of the non-conductive substrate may be insufficient. On the other hand, when it exceeds 900 deniers, it is difficult to remove the non-conductive substrate when electrically joining.

(2-2) Joining structure The joining structure of the conductive base material and the non-conductive base material is not particularly limited. However, since the breathability and flexibility of being a woven fabric can be maintained, the respective woven fabrics are connected. Preferred examples include a joining structure that is woven so as to sew together with a binding yarn, and a joining structure in which a warp of one woven fabric is hooked on a weft of the other woven fabric.

  1 and 2, a flat insulating covering electric conductor 10 according to the first embodiment of the present invention includes a conductive base material 11 and a non-conductive member joined to cover both surfaces of the conductive base material 11. The substrate 21 and the substrate 26 are provided.

  The conductive base material 11 is the same as the conductive yarn 12 formed by winding a copper wire 16 as a single linear metal having a thickness of 100 μm in the S direction around a core yarn 15 made of a spun yarn of 50 denier polyester fiber. Conductive yarns 13 formed by winding one copper wire 16 having a thickness of 100 μm on the core yarn 15 in the Z direction are alternately used as warp yarns, and the core yarn 17 made of spun yarn of 50 denier polyester fiber is used as a thick yarn.

This is a woven fabric that is arranged and used for wefts, and is woven with plain weaves with a warp and weft density of about 35 yarns / inch.

  One non-conductive substrate 21 uses non-conductive yarn 20 made of a spun yarn of 150 denier polyester fiber as warp yarn 22 and weft yarn 23, and the density of both warp yarn 22 and weft yarn 23 is about 70 / inch. This is a woven fabric made of plain weave. The other non-conductive substrate 26 also uses the non-conductive yarn 20 made of a spun yarn of 150 denier polyester fiber as the warp yarn 27 and the weft yarn 28, and the density of both the warp yarn 27 and the weft yarn 28 is about 70 / inch. This is a woven fabric made of plain weave.

  The conductive base material 11 and the two non-conductive base materials 21 and 26 use 50 denier spun yarn of polyester fiber as the binding yarn 29, and are woven so as to be sewn together with the binding yarn 29, that is, The woven fabrics 11, 21, and 26 are joined by engaging the binding yarns 29 with some warp yarns.

According to the flat type insulation coating body 10 of the present embodiment, the following effects (a) to (i) can be obtained.
(A) Due to the three-layer structure in which the non-conductive base materials 21 and 26 are provided on both surfaces of the conductive base material 11, the conductive base material 11 is not exposed on both surfaces of the flat insulation coating current-carrying body 10, Insulation function.

(C) Since the non-conductive base materials 21 and 26 are formed of the non-conductive yarn 20 made of a thermoplastic polyester fiber yarn, a part of the non-conductive base material 21 and 26 can be heated and melted with a soldering iron or the like. It becomes easy to solder to the copper wires 16 and 18 of the conductive base material 11 exposed to the part, and it is easy to use as a current-carrying member used for the purpose of supplying current to electric / electronic devices.

(D) The copper wire 16 spreads over both surfaces of the conductive base material 11 and is rough (mesh shape), and therefore the surface area of the copper wire 16 is much larger than the surface area of the linear conductor of the conventional lead wire. Because it is large, it has high heat dissipation of resistance heat generated during energization.
(E) Since the conductive base material 11 and the two non-conductive base materials 21 and 26 are made of woven fabric, there is air permeability, and the heat dissipation effect is also high in that respect.

(G) By using two types of copper wires 16 and 18 having different wire diameters, a large amount of current can flow in the direction of the copper wire 16 having a large wire diameter, and flexibility in the direction of the copper wire 18 having a small wire diameter. Can be held.
(H) The conductive yarns 12 and 14 in which the copper wires 16 and 18 are wound in the S direction and the conductive yarns 13 and 19 in which the copper wires 16 and 18 are wound in the Z direction are alternately arranged on the warp and the weft of the conductive substrate 11 Therefore, the fabric can be prevented from curling.
(I) Since the conductive base material 11 and the two non-conductive base materials 21 and 26 are joined together by the binding yarn 29, the conductive yarn is produced when the flat insulating covering conductive body 10 is bent. It is possible to prevent 12, 13, 14, and 19 from being exposed on the surface of the flat insulating covering conductive body 10.
