Description

  The present invention relates to a conductive fabric, and more particularly to a conductive fabric that includes conductive yarns and non-conductive yarns, and some of the conductive yarns are electrically insulated from other conductive yarns and external members. is there.

  Conductive fabrics containing conductive yarns are known, and are used for applications such as heaters and various sensors using conductivity. For example, this type of conductive fabric is used as a seat skin (seat cover) of a vehicle seat, and is used as a seat skin provided with a seat heater or a capacitive seating sensor.

  When energizing a conductive fabric including a conductive yarn, the conductive yarn is often connected to another conductive connecting member at the end of the conductive fabric. The connecting member is further connected to a power source, a control device, and the like. As a method for connecting the conductive yarn to the connecting member at the end of the conductive fabric, the method disclosed in Patent Document 1 is known. In other words, after removing a part of the insulating fibers (non-conductive yarn) constituting the cloth material, dividing the cloth material body and the cloth material piece, and exposing a plurality of conductive wire materials (conductive yarn) from the divided portions This is a method of electrically connecting the conductive wire to the connecting member by wrapping and sewing the conductive wire exposed from the divided portion with the connecting member.

JP 2010-245006 A

  The above method is suitable as a method for electrically connecting all the conductive yarns existing in a certain region in the conductive fabric to the connecting member. However, for example, when using a conductive fabric as a heater, the heater output is adjusted depending on the number (density) of conductive yarns to be energized, or the adjacent region in a single conductive fabric is not heated with the place to be heated. When conductive yarns that are electrically connected to the connection member and conductive yarns that are not connected to the connection member and are electrically insulated from the connection member are mixed or adjacent to each other in a certain area, as in the case of providing a location In this case, the above-described method of wrapping the conductive wire exposed from the dividing portion together with the connecting member cannot be used as it is.

  For example, as shown in FIG. 5, after the conductive yarn 42 is exposed from the dividing portion 44 by the method disclosed in Patent Document 1, a conductive yarn that is not desired to be electrically connected to the connecting member, that is, an unused conductive yarn. If 42b is cut | disconnected in the location of the edge 41a of the conductive fabric 41, it is possible to set the electrically conductive thread | yarn which is not electrically connected to a connection member, utilizing the said method. If the conductive material on the cut surface of the unused conductive yarn 42b does not come into contact with the connection member when the conductive sheet-like connection member is attached to the end edge 41a of the conductive fabric 41, it is Electrical insulation between the used conductive yarn 42b and the connecting member is ensured. In practice, however, the conductive material exposed on the cross section of the cut unused conductive yarn 42b can easily come into contact with the connecting member only by cutting the unused conductive yarn 42b at the end 41a of the conductive fabric body 41. And electrical connection will be formed between connection members.

  Even if the cut surface of the unused conductive yarn 42b does not come into contact with the connecting member in the connecting step of the connecting member, the conductive fabric 41 and the connecting member are not energized during the energization of the conductive yarn 42a for energization connected to the connecting member. For example, when a force that causes bending deformation is applied, the cut surface of the unused conductive yarn 42b comes into contact with the connecting member, or the unused conductive yarn 42b and the conductive conductive yarn 41a adjacent thereto contact with each other. There is a risk that it will easily occur. Then, current is supplied to the unused conductive yarn 42b via the connecting member, or a short circuit occurs between the unused conductive yarn 42b and the conductive yarn 42a for energization adjacent thereto.

  Therefore, it is possible to adopt a method of attaching the connecting member after covering the portion where the unused conductive yarn 42a is cut at the position of the edge 41a of the conductive fabric 41 with an insulating member such as an insulating tape-like cloth material. . Then, although insulation with respect to the connection member of the edge part of an unused conductive yarn can be ensured, the insulating member which is a member different from the conductive fabric 41 is needed.

  The problem to be solved by the present invention is that, in a conductive fabric including a conductive yarn and a non-conductive yarn, when connecting an external member such as a conductive connection member to a conductive yarn that conducts a part of current, a separate member is used. An object of the present invention is to provide a conductive fabric that can insulate the end portion of a conductive yarn that is not energized from a connecting member and the conductive yarn that is energized without using an insulating member.

  In order to solve the above-described problems, the conductive fabric according to the present invention is a conductive fabric including conductive yarns and non-conductive yarns, and the fabric edge in the region including at least a part of the conductive yarns is other than that. The gist is that it is provided at a position recessed inward of the fabric surface from the fabric edge of the region.

  Here, the fabric edge in the region including the end portion of the at least part of the conductive yarn is removed so that a part of the structure of the conductive fabric includes the end portion of the part of the conductive yarn and the non-conductive yarn. It is good to be provided in the position dented inside the fabric surface rather than the fabric edge of the other area.

  According to the conductive fabric according to the invention, when a member such as a connecting member having conductivity is connected to the end of the conductive yarn to be energized, the terminal of the conductive yarn that is not energized performs the connection member and the like. Since the conductive yarn is formed at a position away from the end of the conductive yarn, the conductive yarn that is not energized is electrically insulated from the connection member and other conductive yarns. Therefore, when the conductive yarn to be energized is energized, the conductive yarn that is not energized is not energized, or does not contact with the nearby energized conductive yarn to cause a short circuit. Furthermore, since the electrical insulation of the conductive yarn that is not energized is achieved only by determining the position of the end of the conductive yarn that is not energized as described above, a separate insulating member such as a tape-like cloth material When connecting a conventional conductive fabric to a connecting member, the number of parts is reduced compared to the case where a part of the conductive yarn is cut and the end is covered with an insulating member.

  In addition, when the above configuration is achieved by removing a part of the structure of the conductive fabric including the ends of some of the conductive yarns and non-conductive yarns, It is possible to ensure electrical insulation between a conductive thread that is not energized and an external member such as a connecting member and a surrounding conductive thread that is energized by simply removing the end so as to be cut out together with the surrounding non-conductive thread. it can. As a result, even when there are a large number of conductive yarns that are energized and conductive yarns that are not energized, the ends of the conductive yarns that are not energized can be reliably electrically insulated. Therefore, it is possible to easily perform the insulation process as compared with the conventional method, and it is possible to prevent the occurrence of deficiencies in the insulation process, such as forgetting to perform the insulation process at some locations. In addition, since the location where the conductive fabric has been removed can be clearly seen, whether or not each conductive yarn is insulated, that is, whether the conductive yarn is not energized or is energized. Can be easily determined by the presence or absence of the removed portion. Thus, the presence or absence of the removed portion can also be used as an index in the process of manufacturing the conductive fabric and connecting the connecting member.

It is a front view of the electrically conductive fabric concerning 1st embodiment of this invention. The state which attached the connection member to the edge of the conductive fabric of FIG. 1 is shown, (a) is a front view, (b) and (c) are the AA sectional view and BB section of (a), respectively. FIG. It is the schematic which shows the manufacturing method of the electrically conductive fabric concerning 1st embodiment of this invention, and the attachment method of a connection member. It is the schematic which shows the manufacturing method of the electrically conductive fabric concerning 2nd embodiment of this invention, and the attachment method of a connection member. It is a front view of the conductive fabric which provided the unused conductive thread using the manufacturing method of the conventional conductive fabric.

  First, the detail of the electrically conductive fabric concerning 1st embodiment of this invention is demonstrated based on FIG.1 and FIG.2. FIG. 1 shows a front view of a conductive fabric according to an embodiment of the present invention. The conductive fabric according to the present embodiment can be suitably used as a heater device disposed on the skin of a vehicle seat that itself generates heat to be a heater device or the back side of a seat cover.

  The conductive fabric 1 has a conductive yarn 2 and a non-conductive yarn. As the conductive yarn 2, use is made of a fibrous material having various conductivity such as a conductive wire made of only a conductive material such as a fine metal wire, or a conductive yarn formed by combining these conductive wire and other fibers. Can do. As the conductive wire, it is preferable to use a fine stainless steel wire having high tensile strength and corrosion resistance. The outer periphery of the conductive wire may be covered with a resin or the like. Various non-conductive fiber materials can be used as the non-conductive yarn.

  As long as the conductive fabric 1 includes the conductive yarn 2 and the non-conductive yarn, the conductive fabric 1 may be composed of any structure such as a knitted fabric, a woven fabric, or a non-woven fabric. In this embodiment, the conductive fabric 1 is formed of a woven fabric, and the conductive yarns 2 are arranged in a substantially straight line at equal intervals as a part of the warp or the weft. When the conductive yarn 2 is energized, the conductive yarn 2 generates heat, and the conductive fabric 1 functions as a planar heater device. In each drawing, the non-conductive yarn is not clearly drawn in the conductive fabric 1, but the region of the conductive fabric 1 other than the portion where the conductive yarn 2 is arranged is constituted by the non-conductive yarn. Yes. It is desirable that the conductive yarn 2 does not appear on the surface of the conductive fabric 1 so that other members, the user's body, and the like do not contact the conductive yarn 2.

  When the conductive fabric 1 is formed by cutting a long woven fabric into a shape necessary for various uses, a desired amount of heating may differ depending on the use. For example, when used as a vehicle seat heater, the desired amount of heating differs depending on the region of the seat. In this case, not all the conductive yarns 2 are energized, but the conductive yarns 2a for energization and the non-conductive conductive yarns 2b that are not energized are provided periodically, and the ratio (density) of the conductive yarns 2a for energization By appropriately setting the value, a desired heating amount may be exhibited depending on the application and region. In the present embodiment, as an example, two conductive yarns 2a for energization and two unused conductive yarns 2b are alternately arranged.

  The cloth edge E provided in the direction orthogonal to the arrangement direction of the conductive yarn of the conductive cloth 1 is a substantially straight non-cut edge 1a and a curved shape formed inside the cloth surface from the non-cut edge 1a. It consists of what connected the cutting part edge 3a. The cut portion edge 3a is formed to include a position where the end of the unused conductive yarn 2b is disposed. On the other hand, the fabric edge E in the other region including the position of the end portion of the energizing conductive yarn 2a is composed of the non-cut edge 1a. In other words, the fabric edge E (cut portion edge 3a) in the region including the end portion of the unused conductive yarn 2b is located on the inner side of the fabric surface than the fabric edge E (non-cut edge 1a) in the other region. It is the state formed in the position dented in.

  Both ends of the conductive yarn 2a for energization extend outward from the non-cut end edge 1a of the conductive fabric 1 and are exposed without being surrounded by the non-conductive yarn. Further, when the outer periphery of the energizing conductive yarn 2a is covered with resin or the like, the covering material is removed from the outer periphery of the extending portion 2a1, and the conductive material is exposed. When the conductive fabric 1 is used as a heater, the exposed extended portion 2a1 is connected to the conductive connecting member 6 as will be described later.

  On the other hand, a cut edge 3a is formed at the end of the unused conductive yarn 2b. The region surrounded by the virtual extrapolated end edge 1a ′, which is an extrapolated line of the non-excised end edge 1a arranged on both sides of the excised part edge 3a, and the region surrounded by the excised part end edge 3a is also non-conductive The cut portion 3 has no thread. The unused conductive yarn 2b has a terminal at the position of the cut edge 3a. That is, the end of the unused conductive yarn 2b is retracted to the inside of the fabric surface from the non-cut edge 1a.

  As will be described later, the size and shape of the cut-out portion 3 are determined when the connection member 6 is attached to the extended portion 2a1 of the conductive yarn 2a for energization extending from the non-cut-off end edge 1a. The end of the unused conductive yarn 2b needs to be reliably retracted from 6a, but if it is formed too large, the strength of the entire conductive fabric 1 will be lowered, so it is necessary to select an appropriate size There is. As for the shape, a substantially semicircular cut portion 3 is formed in FIG. 1 and the end of the unused conductive yarn 2b is arranged at a position farthest from the extrapolated end edge 1a ′ on the arc. Then, the end portion of the unused conductive yarn 2b can be effectively retracted to the inside of the fabric surface. In addition, although an insulating coating may be applied by forming a resin film or the like on the end of the unused conductive yarn 2b having a terminal at the position of the cut edge 3a, as will be described later, the cut portion 3 is formed. As a result, sufficient electrical insulation is formed between an external member such as a conductive member and the neighboring conductive yarn 2a for energization, so that it is not necessary to apply an insulating coating.

  In FIG. 1, no other conductive fabric or the like is connected to the tip of the extending portion 2 a 1 of the conductive yarn 2 a for energization. However, as shown in FIG. It can also be set as the state connected with the conductive fabric 1 via 2a. In such a state, the extended portions 2a1 of the conductive yarns 2a for energization maintain a relative position to each other and are kept straight, and the connecting member 6 is sewn when the cut portion 3 is formed. The workability at the time of connection by such as is improved.

  FIG. 2 shows a state in which the connection member 6 is attached to the extending portion 2a1 of the conductive yarn 2a for energization of the conductive fabric 1 of FIG. The connection member 6 is a sheet member in which a conductive surface 6a having conductivity is formed on at least one surface. Examples of the conductive sheet member include a member in which a conductive material (for example, copper) is formed in a sheet shape, and a conductive fabric including a thread formed of a conductive material. The connecting member 6 has a substantially “U” cross section so that the conductive surface 6a is inside the fabric surface and the extended portion 2a1 of the conductive yarn 2a for energization is sandwiched, and is sewn or the like. Attached to the fabric edge E. The connecting member 6 is connected to a power source via an electric wire 7.

  FIG. 2B shows a cross-sectional view of the position where the conductive yarn 2a for energization is arranged. The extending portion 2a1 is wrapped by the connecting member 6 and is in contact with the conductive surface 6a of the connecting member 6. Thereby, conduction | electrical_connection is formed between the electrically conductive thread 2a and the connection member 6, and the electrically conductive cloth 1 is heated by energizing the electrically conductive thread 2a. In addition, in FIG.2 (b), although the extension part 2a1 is extended in linear form, you may be wrapped in the connection member 6 in the state bent in the middle place.

  On the other hand, FIG. 2C shows a cross-sectional view of the position where the unused conductive yarn 2b is arranged. Since the connecting member 6 is a long and thin sheet extending over the ends of the plurality of conductive yarns 2, the entire fabric edge E of the conductive fabric 1 is wrapped up, including the location where the cutout 3 is formed. However, the end portion of the unused conductive yarn 2b is retracted to the inside of the fabric surface by the cutout portion 3, and does not contact the conductive surface 6a of the connecting member 6. Therefore, no continuity is formed between the unused conductive yarn 2b and the connection member 6, and even if a current is supplied from the power source to the connection member 6 and the conduction conductive yarn 2a is energized, the unused conductive yarn 2b. Is not energized. Further, it does not cause a short circuit due to contact with the extending portion 2a1 of the adjacent conductive yarn 2a for energization.

  The position where the end of the unused conductive yarn 2b is sufficiently separated from the conductive surface 6a of the connecting member 6 by forming the cut portion edge 3a sufficiently inside the fabric surface of the conductive fabric 1 If the connecting member 6 or the conductive fabric 1 is subjected to bending deformation during use, the end portion of the unused conductive yarn 2b and the conductive surface 6a of the connecting member 6 or the adjacent conductive yarn for energization are used. The extension part 2a1 of 2a does not contact. When the conductive fabric 1 is used as a seat heater for a vehicle seat, the conductive fabric 1 frequently undergoes deformation such as bending as the passengers get on and off and move in a seated state. Thus, the configuration in which the cut portion 3 is provided at the end portion of the unused conductive yarn 2b is particularly effective.

  Next, an example of a method for manufacturing the conductive fabric 1 according to the embodiment and a method for connecting the connection member 6 to the manufactured conductive fabric 1 will be described with reference to FIG. First, as shown in FIG. 3A, a rectangular conductive fabric (fabric body) 1 is formed in a state of being connected to the fabric piece 5 by the conductive yarn 2 through the dividing portion 4 from which the nonconductive yarn is removed. In order to form the conductive fabric 1 in such a state, a rectangular original fabric is prepared from the region of the conductive fabric 1 to the divided portion 4 and the region of the fabric piece 5, and the non-conductive yarn is formed from the region to be the divided portion 4. Only need to be removed. As a method for forming the divided portion 4, there is a method in which the non-conductive yarn is melted or burned by irradiating the entire region to be the divided portion 4 with laser light. Alternatively, as described in Patent Document 1, a non-cutting end edge 1a and an extrapolating end edge 1a ′ of the conductive cloth 1 are cut linearly with a blade or a laser, and then the piece of cloth is cut. The dividing portion 4 can also be formed by pulling away from the conductive fabric 1 so as to extract the portion to be 5. In this case, unlike the state shown in FIG. 3A and the like, the energizing conductive yarn 2a in the fabric piece 5 is pulled out to the dividing portion 4 by the width of the dividing portion 4. ing. Regardless of which method is used, when a laser is used, the laser output and wavelength are within the range in which the non-conductive yarn is melted or burned while the conductive material constituting the conductive yarn 2 is not melted or burned. Must be set to In addition, when the conductive yarn 2a for energization has a coating of resin or the like on the outer periphery, it is also necessary to remove it. In the case where the fabric piece 5 is not formed, the non-conductive yarn outside the non-cut end edge 1a and the extrapolated end edge 1a 'may be completely removed by any one of the above methods.

  Next, which conductive yarn 2 is to be used as the unused conductive yarn 2b is selected, and the cutting means is used to include a portion overlapping the cut edge 3a of the selected unused conductive yarn 2b and the surrounding nonconductive yarn. The conductive fabric 1 in the left region is removed so as to include the extrapolated end edge 1a ′, and the cut portion 3 is formed. At this time, the unused conductive yarn 2b that has been cut and remains on the part 4 and the fabric piece 5 side is also removed.

  Any cutting means may be used as long as it can cut both the conductive yarn 2 and the non-conductive yarn at the portion to be the cut edge 3a. Use of a punch-shaped blade is preferable because the cut portion 3 can be formed by hollowing out the fabric structure simply by pressing from above the fabric surface of the conductive fabric 1.

  The conductive fabric 1 after the cut portion 3 is formed by the cutting means is connected to the fabric piece 5 by the conductive yarn 2a for energization as shown in FIG. 3B, and the width of the dividing portion 4 is kept constant. . In this state, the connecting member 6 is disposed on the dividing portion 4 as shown in FIG. At this time, it is necessary to arrange the connection member 6 at a position where the conductive surface 6a of the connection member 6 is surely in contact with the conductive yarn 2a for energization. In addition, it is necessary to dispose the connection member 6 at a position where the end of the unused conductive yarn 2b existing at the position of the cut edge 3a does not contact the conductive surface 6a of the connection member 6. In FIG.3 (c), the connection member 6 is arrange | positioned so that the whole cutting part 3 may not overlap with the conductive surface 6a of the connection member 6, and it is suitable at this point. Further, as the connection member 6, it is necessary to select a connection member 6 whose conductive surface 6a is not too wide.

  Finally, as shown in FIG. 3 (d), the connecting member 6 may be fixed to the conductive fabric 1 by bending and sewing the connecting member 6 so as to wrap the fabric edge 1 a. At this time, the fabric piece 5 may be cut off or left in a state of being bent together with the connecting member 6 on the conductive fabric 1 side.

  In the first embodiment described above, by forming a cut portion in the fabric edge of the region including the end portion of the unused conductive yarn, the fabric edge of the region including the end portion of the unused conductive yarn is changed to the other end. Although it formed in the fabric surface inside rather than the fabric edge of the area | region, methods other than forming a cut part are also applicable. In the second embodiment, instead of forming the cut portion, the folded edge is formed in the region including the end portion of the unused conductive yarn, so that the fabric edge of the region including the end portion of the unused conductive yarn is formed. Is formed on the inner side of the fabric surface than the edge of the fabric in the other region. Details of the conductive fabric according to the second embodiment will be described with reference to the manufacturing method shown in FIG.

  The conductive fabric 21 according to the second embodiment has the same configuration as that of the conductive fabric 1 according to the first embodiment except for the configuration around the end of the unused conductive yarn 22b. First, as shown in FIG. 4A, the conductive fabric 21 is formed in a state where the conductive fabric 21 is connected by the conductive yarn 22 through the fabric piece 25 and the dividing portion 24. This step is the same as that in the first embodiment.

  Next, which conductive yarn 22 is to be used as the unused conductive yarn 22b is selected, and as shown in FIG. 4B, the selected unused conductive yarn 22b is cut at the location of the fabric edge 21a. At the same time, a cut line 23a is formed parallel to the direction in which the unused conductive yarn 22b is arranged in the portion made of the nonconductive yarn arranged on both sides of the end portion of the unused conductive yarn 22b, and the fabric edge 21a is divided. To do. The cut line 23a may be formed using a cutter such as a cutter or a scissors, laser light, or the like.

  Next, as shown in FIG. 4C, the folded portion 23 b including the end portion of the conductive yarn 22 b sandwiched between the two cut lines 23 a is folded back toward the inside of the conductive fabric 21. It is formed. At this time, a straight line connecting the ends on the fabric surface side of the two cut lines 23a, that is, a fold line 23c at the base of the folded piece 23b, and the cut line 23a are the fabric edge E where the folded portion 23 is formed. It becomes. That is, the new fabric edge E is a line obtained by combining the original fabric edge 21a in the region other than the portion where the folded portion 23 is formed, the folded line 23c, and the cut line 23a. As a result, the fabric edge E (folding line 23c and cut 23a) in the region including the end portion of the unused conductive yarn 22b is more fabric than the fabric edge E (original fabric edge 21a) in the other region. It is in a state formed inside the surface.

  Next, as in the case of the first embodiment, the connection member 26 is attached to the conductive fabric 21 as shown in FIG. At this time, it is necessary to arrange the connection member 26 at a position where the conductive surface 26a of the connection member 6 is surely in contact with the conductive yarn 22a for energization. In addition, it is necessary to arrange the connection member 26 at a position where the unused conductive yarn 22b in the folded piece 23b does not contact the conductive surface 26a of the connection member 26.

  Finally, as in the first embodiment, the connecting member 26 is bent and stitched to fix the connecting member 26 to the conductive fabric 21 (FIG. 4E). At this time, the folded piece 23b may be fixed to the conductive cloth 21 by being sewn to the conductive cloth 21 together with the connecting member 26, or may be fixed to the conductive cloth 21 first between the steps of FIG. 4 (d) and (e). You may keep it. The latter method increases the number of steps, but facilitates the work of arranging and fixing the connection member 26.

  As described above, by forming the cutout portion 3 and the turn-back portion 23, the end portions of the unused conductive yarns are arranged on the fabric surface with respect to the regions made of the surrounding non-conductive yarns and the fabric edges of the other regions. If the conductive yarn for energization and the unused conductive yarn are adjacent to each other, the insulation of the unused conductive yarn can be easily ensured by retracting to the inside. When the folded portion 23 is formed as in the second embodiment, when the connecting member is attached, the thickness of the fabric edge at the position where the folded portion 23 is formed increases, but this is not desired. Should just choose to form a cutting part like 1st embodiment. Conversely, when it is desired to increase the strength of the fabric edge, the conductive fabric according to the second embodiment in which the folded portion is formed may be selected.

  As mentioned above, although two embodiment of this invention was described in detail, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention. For example, in the above-described embodiment, the energization conductive yarn and the non-use conductive yarn are periodically arranged at equal intervals, but they may be arranged in any manner. For example, when used as a seat heater, if it is desired to change the amount of heating according to the part of the human body that comes into contact, a region where the density of the conductive yarn for energization is high and low may be provided at a certain position. Furthermore, in order to set the boundary of such an area | region reliably, you may form the area | region where the unused conductive yarn concentrated and provided in the boundary of an area | region. Moreover, it is not necessary to form the conductive fabric in a rectangular shape, and it may be formed in a shape corresponding to various uses.

  In the above embodiment, the cut portion and the folded piece are separately formed at the end of each unused conductive yarn. However, a large cut portion or folded portion is formed at the ends of a plurality of adjacent unused conductive yarns. It may be formed. However, care must be taken not to impair the strength of the entire conductive fabric. Finally, it is not always necessary to provide the dividing portion and the fabric piece.
