。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an IJ elongated conductive element. More specifically, the present invention relates to an elongation conductive element of action elongation setting type equipped with an elongation suppressing member.

〈従来の技術〉 人体の肘、膝等の屈曲部分のような大きな伸長変形を電
気的に検出することが必要な場合がある。<Prior Art> There are cases where it is necessary to electrically detect large elongation deformations such as bending parts of the human body, such as elbows and knees.

このような検出に際して伸長変形によって電気抵抗値が

抗値が増大する素材を用いる方法の何れかを採用するこ
とが考えられる。For such detection, it is conceivable to adopt either a method using a material whose electrical resistance value decreases as it is stretched and deformed, or a method that uses a material whose electrical resistance value increases when it is stretched and deformed.

た。However, until now, no material has been known that has the property of reducing its electrical resistance value due to elongation deformation. Therefore, by detecting the decrease in electrical resistance value caused by elongation deformation, it is possible to determine whether or not the object to be measured is elongated, the amount of elongation, and the amount of elongation. Elements capable of detecting the frequency of compression have also not been developed.

の検出には用いることができない。Therefore, it is conceivable to detect elongated deformation using an element that takes advantage of the property that the electric resistance value increases due to elongated deformation, such as a strain dart. Sunawachi, for example Kon'
When a thin metal wire such as Stantus Adpanse or Nichrome is pulled, its electrical resistance increases, and this property is used to make strain darts. However, since the elongation rate of this type of metal wire is extremely small (less than 1 inch), the strain r-no can only cope with minute deformations of the object to be measured. It cannot be used to detect large elongation deformations.

However, although piezoelectric elements detect mechanical strain and deformation as voltage changes, they are only suitable for applications involving minute deformations, similar to Stray/Guno. In addition, the latter pressure-sensitive conductive rubber has an electrical resistance value that decreases when subjected to compressive deformation, but does not exhibit a direct decrease in electrical resistance when subjected to elongated deformation.

Therefore, with conventionally known elements, it is not possible to detect the elongation behavior of an object that undergoes elongation deformation, especially a considerable amount of elongation deformation, that is, the presence or absence of elongation, the amount of elongation, the frequency of compression accompanied by elongation, etc.

伸長を伴う圧縮の頻度等を検出することができる。If electrodes are attached to any two points on a sheet-like object as described above and the sheet-like object is stretched between the electrodes, the electrical resistance between the electrodes on the sheet-like object will decrease, so it is possible to determine whether or not the electrical resistance has decreased. By measuring the extent between two electrodes, it is possible to determine whether or not the object to be measured is elongated and the degree of elongation. In addition, since these sheet-like materials, especially the latter deformable conductive knitted fabrics, can undergo a considerable amount of elongation deformation, it is important to understand the elongation behavior of objects that undergo a considerable amount of elongation deformation, that is, the presence or absence of elongation, the amount of elongation,
It is possible to detect the frequency of compression accompanied by expansion.

なくなるという問題点を有する。The elongated conductive element configured in this way exhibits outstanding performance in detecting the elongation behavior of an object that undergoes a considerable amount of elongation deformation, but when attached to the object and used, the following It has some problems. That is, unless the elongated conductive element is attached to the object in a state immediately before the elongation at which the resistance value of the elongated conductive element starts to decrease from 10 Ω in the insulated state, the elongation of the object cannot be detected correctly. Therefore, special care must be taken when attaching the elongated conductive element configured as described above to an object. In addition, in the case of an elongated conductive element having a more structured structure as described above, if an excessive tension is applied and the elongated conductive element is excessively stretched, the characteristics of the elongated conductive element change and there is a risk of destruction. This has the problem that it cannot be reused.

あれば除去すればよい。When attaching an action elongation setting type elongation conductive element equipped with an elongation suppressing member for initial setting elongation to an object, the elongation conductive element is held until its elongation stops (in the case of the first type of elongation suppressing member). (In the case of the second type of elongation suppressing member, until the tensile resistance increases), the elongated conductive element Denkaku is attached to the object in that state.

可能となる。In addition, if the initial setting elongation of the elongation suppressing member for the initial setting elongation is made slightly larger than the elongation immediately before the elongation starts to decrease from 10 Ω in the insulated state as defined above, the elongation of the elongated conductive element is increased. It can be used by setting the elongation to such a degree that the relationship between the deformation value and the logarithm value of the resistance value is a direct relationship. The elongated conductive element provided with the elongation suppressing member having the initial elongation set in this manner is used to detect physical displacement such as elongation of the object based on the resistance value of the elongated conductive element. In this case, the displacement amount 11j can be determined with good accuracy.

不能になるような事が防がれる。Next, the elongation suppressing member for breaking prevention limit elongation is used while being attached to the elongated conductive element. Therefore, when the elongated conductive element attached to the object is extremely stretched, the elongation suppressing member for the limit elongation for preventing destruction acts, and the element is elongated beyond the set elongation limit. prevent that. As a result, the elongated conductive element is prevented from being destroyed or rendered unusable.

In the case of double knitting, substantially uniform deformation conductivity can be obtained in any direction of the knitting structure, so it is more preferable. Incidentally, the deformation conductivity with respect to minute deformation and large deformation can be obtained by appropriately selecting the configuration (thread thickness, density, thread size, etc.) of each woven fabric. The shape of the knitted fabric includes all shapes using the structure of the knitted fabric, such as sheet-like and cylindrical shapes.

り好ましい。The above-mentioned modified conductive knitted fabric is manufactured by first plating a knitted fabric made from conductive yarn to which an electrically insulating fiber is coated with a conductive substance by plating, coating, thermal spraying, etc., or plating an electrically insulating knitted fabric. A conductive knitted fabric to which a conductive substance has been applied by means such as , coating, or thermal spraying is prepared, and this knitted fabric is subjected to ultrasonic waves, high-speed jetting of water or air, or a medium in which a laminar flow with a large difference in flow velocity occurs. This is done by selectively peeling off the conductive substance between the intertwined portions of the yarn and the intertwined portions by applying physical stress, such as by applying physical stress. Therefore, only certain parts of the yarn that make up the modified conductive knitted fabric are electrically insulated, and other parts are plated with conductive substances such as copper, nickel, silver, carbine, etc.
Conductivity is imparted by conductive means such as coating or thermal spraying. In particular, in the case of multifilament or spun yarn, each filament or short fiber comes into contact with each other under minute stress, which is more preferable for forming a highly sensitive deformable knitted fabric.

操作性の面で優れ、工業的により好ましい。The connection between the electrode made of a metal plate, conductive fabric, or conductive elastomer sheet and the stretched conductive sheet is made using conductive resin Ti.
It is preferable to do so through the contact resistance because the contact resistance is low and the mechanical strength against stretching and repetition is increased. The conductive resin layer referred to here includes commonly used plastic adhesives such as epoxy, acrylic, and ester adhesives, urethane adhesives, latex adhesives, and hot-melting iA insect-type polymers. For example, it is a layer made of a conductive resin having a base material such as a polyester resin or a polyamide resin, and mixed therein with an appropriate amount of conductive filler, usually within a range of 5 to 50 volume coefficients. The i, n electrically conductive filler herein refers to metals such as nickel, copper, iron, aluminum, gold, and silver, or their alloys, or conductive carbon, and is in the form of powder or short fibers. . The thickness of the twisted conductive resin layer needs to be 1 μm or more, and it depends on the use of the elongated conductive element.
Usually, a thickness of 2 μm or more and 50 μm or less is preferable in terms of adhesive strength with the stretched conductive sheet and electrode plate, contact resistance, and cost, but the thickness is not limited to this. If the thickness of the conductive resin layer is less than 1 μm, the adhesive strength will be poor. It should be noted that when the conductive resin is made of heat-melting type 4+7 mer as a base material, it can be used in the form of a sheet or film, which is excellent in terms of operability and is more preferable from an industrial perspective.

It has a high adhesive strength with the conductive resin layer and is more likely to cause dielectric breakdown, so the amount of conductive filler mixed in can be reduced, reducing costs and reducing the adhesive strength of the conductive resin layer. More preferred.

ができる。Next, the setting of the amount of loosening of the elongation suppressing member will be explained. In the examples shown in Figures 1 and 3, if the amount of loosening is set in accordance with the degree of elongation at A in Figure 2, the switch can be used as a highly responsive switch without malfunctioning even with slight elongation deformation. I can do it. When using the two elongation suppressing members shown in Fig. 4 and Fig. 5, the initial setting elongation and loosening of the elongation suppressing member are set corresponding to the elongation B in Fig. 2, and If the amount of loosening of the elongation suppressing member for prevention limit elongation is set corresponding to the elongation of C in Figure 2, the elongation of the treasure and the logarithm of the resistance value of the 11+l-1a conductive element will have a linear relationship VC. The elongated groove i'j R can be used in a certain offshore head area, and accurate object displacement 1 measurement can be performed. In addition, if the former is set with an amount of slack corresponding to the elongation of A in Fig. 2, and the latter is set with an amount of slack corresponding to the elongation of D in Fig. 2, the elongated conductive element will malfunction. It can be used as a switching element with high durability.
