Description

Multi-directional electrically conductive structure < RTI ID = 0.0 >

TECHNICAL FIELD The present invention relates to a conductive structure, and more particularly, to a multi-directional conductive structure capable of expanding and contracting in multiple directions by forming a planar body surrounded by an elastic structure.

Generally, a conductive wire is manufactured by coating or coating an insulating resin layer on the outside of a copper wire. These conductive wires are relatively large in diameter and have no ductility, and are heavy and therefore used as a power supply line or a heating line in locations that do not require elasticity or activity.

Meanwhile, in recent years, it has been known that clothes can be applied to articles requiring sufficient activity and comfort, such as smart clothes, which apply various signal transmission techniques to clothes and respond to predetermined conditions by sensing external stimuli and incorporating various digital devices A conductive wire is required.

Accordingly, in recent years, conductive wires manufactured by plating a conductive metal such as copper (Cu) to fiber yarn have been commercialized. The conductive wire in the form of plating a conductive metal on a fiber yarn is a method of plating a conductive metal on the fiber yarn and thus can be easily applied because of a comparatively simple manufacturing method and is advantageous in that it is smaller in diameter and lighter in weight than conventional wires However, when such an electric wire is subjected to an external force or friction during use or is woven by a loom, the plating layer is peeled or damaged by a needle or the like, so that stable conductivity can not be ensured. Particularly, when a tensile force is applied to the fiber yarn while the plating wire is woven in a planar body, the internal fiber yarn is somewhat increased, but the metallic plating layer is not stretched and cracks are generated or broken.

In addition, gold (Au) or silver (Ag), which is excellent in conductivity, can be used as a conductive wire by forming a fine wire to secure sufficient conductivity, but is very vulnerable to a tensile force acting in the longitudinal direction. There is a disadvantage that it can not be applied to a material for a bed requiring cushioning action or a garment requiring stretchability and activity because there is no elasticity due to the nature of the carbon fiber yarn and when continuous friction force acts during use, Or minute electric sparks are generated, so that sufficient durability and safety can not be ensured.

Therefore, it is necessary to develop a multi-directional conductive structure having good stretchability in order to prevent a short circuit.

SUMMARY OF THE INVENTION An object of the present invention is to provide a multi-directional conductive structure capable of preventing a short circuit by allowing a conductor to expand and contract.

It is still another object of the present invention to provide a multi-directional conductive structure capable of maximizing a heat generating area and a degree of bending due to a conductor, thereby increasing a heat distribution.

The multi-directional conductive structure according to the present invention may include a structure capable of expanding and contracting, a planar body configured to wind around the structure, and a planar body having a conductor. This is because the planar body is wound around the structure capable of expanding and contracting, so that the conductor can be expanded and contracted.

Here, the structure may be a cylindrical shape, and the planar body may include a planar body formed to have a predetermined length and a length, and a conductor disposed in a predetermined path on the planar body.

The planar body thus formed can be arranged in the oblique direction of the planar body by weaving the conductor together with the fiber yarn during the weaving process of the planar body.

Further, depending on whether or not the sheet member is heated, the space portion can be configured to expand or contract.

The sheet-like body includes a conductor and a conductor, a film formed by expanding or contracting the conductor to form a space portion, a film formed by joining both surfaces except the space portion, and an air-impermeable film joining portion . ≪ / RTI >

The multi-directional conductive structure thus configured may comprise the steps of providing a stretchable structure, providing a planar body, and forming the planar body around the periphery of the stretchable structure.

The planar body can be constructed so that the planar body can be expanded and contracted by forming a planar body around the structure capable of expanding and contracting.

Here, the structure may be a cylindrical shape, and the planar body may include a planar body formed to have a predetermined length and a length, and a conductor disposed in a predetermined path on the planar body.

On the other hand, the planar body can arrange the conductor in the oblique direction of the planar body by weaving the conductor with the fiber yarn during the weaving process of the planar body.

Since the planar body constructed as described above is bonded to the structure that can be expanded and contracted, the planar body can receive less bending strength, thereby preventing the risk of short-circuiting and providing a large heat distribution.

According to the present invention, the conductor can be expanded and contracted in three directions, thereby preventing a short circuit.

In addition, the heat generating area and the degree of bending by the conductor can be maximized, and the heat distribution can be increased.

The planar body 21 may have elasticity.

For example, the flat body 21 can be woven by weaving yarns or warp yarns. In this case, the flat body 21 can be expanded and contracted in the oblique direction. As another example, the fiber yarn constituting the flat body 21 may be made of a material having elasticity. As another example, the planar body 21 may be an elastic material.

On the other hand, when the planar body 21 is fabricated by a weaving method, the conductor 10 may be supplied together with the fiber yarns constituting the planar body 21 so as to be disposed at the same time as the weave of the planar body 21.

The conductor 10 can be arranged in a direction intersecting with the elongating and contracting direction of the planar body 21. [ The number of the conductors 10 may be plural. In this case, the plurality of conductors 10 may be disposed apart from each other along the elongating / contracting direction of the planar body 21. [ According to the above structure, when the planar body 21 is expanded or contracted, the distance between the plurality of conductors 10 is changed, thereby preventing the conductor 10 from being short-circuited.

2 is a perspective view of a structure 30 according to one embodiment.

Referring to FIG. 2, the structure 30 may have a longer length than the width. For example, the structure 30 may be cylindrical in shape. The structure 30 may be formed as a square shape as well as a cylindrical shape or a triangular shape. The present invention is not limited thereto, and any shape can be used as long as it is a three-dimensional structure that can be stretched or shrunk.

The structure 30 may have elasticity. For example, the structure 30 may be an elastic material such as rubber, silicone, or sponge.

The structure 30 may have elasticity in the longitudinal direction. The structure 30 may have elasticity in the width direction. The structure 30 may have elasticity in three axial directions. The structure 30 thus configured can be formed to be capable of stretching in various directions.

The structure 30 may include a hook and loop fastener such as a detachable hook or a bolt that engages with the planar member 20 shown in Fig.

3 is a perspective view of a multi-directional conductive structure according to one embodiment. Referring to FIG. First, the multi-directional conductive structure 100 may include the conductor 10, the planar member 20, and the structure 30. [

First, the planar body will be described. The planar body 20 may include a planar body 21 formed to have a predetermined length and a length and a conductor 10 having both an anode and a cathode arranged in a predetermined path in the planar body 21 .

The conductors 10 provided in the planar body 21 may be constituted such that they are arranged in a weaving manner or attached in a diagonal direction due to the woven fiber yarn of the planar body 20. [

In addition, the structure 30 may have a cylindrical shape having a longer length than the width. The structure 30 may have a three-dimensional structure and may be a stretchable material in the width direction and the length direction.

The planar body 20 provided with the conductor 10 may be configured to surround the circumference of the structure 30 that can be expanded or contracted.

The planar body 20 is integrally formed by enclosing the stretchable structure 30 so as to impart conductivity to the multi-directional conductive structure.

The planar body 20 is wrapped around the longitudinal direction of the structure body 30 so that the spaces between the wire rods of the conductor 10 provided in the planar body 20 can be expanded and contracted. Specifically, the conductors 10 may be arranged in a direction crossing the longitudinal direction of the structure 30. [ In this case, when the structure 30 is elongated in the longitudinal direction, the entire conductive structure 100 can be stretched while the angle of the conductor 10 with respect to the longitudinal direction is reduced. In addition, when the structure 30 is stretched in the width direction, the entire conductive structure 100 can be stretched while the angle of the conductor 10 with respect to the longitudinal direction increases. That is, by arranging the conductors 10 in the direction crossing the longitudinal direction of the structure 30, it is possible to extend the entire conductive structure 100 even when the conductor 10 is a non-stretchable material.

Due to the structure 30 capable of extending and contracting in multiple directions, the planar body 20 can be configured to be able to expand and contract in three axes in the X, Y, and Z axes.

In other words, due to the stretchability of the structure 30, it is possible to constitute all three axes of expansion and contraction of the spacing spaces between the wires 10 of the conductor 10.

The conductor 10 can be wound around the stretchable structure 30 to secure an allowable length to be elongated so that when the structure 30 is stretched in the longitudinal direction, It is possible.

The structure 30 may have elasticity in at least two axial directions, and the surrounding body may be configured to have elasticity in at least two axial directions.

Since the multi-directional conductive structure 100 constructed as described above can be expanded and contracted in three axes, it is possible to prevent a short circuit, thereby improving the durability, maximizing the heat generating area and the degree of bending by the conductor, There is an advantage that it can be made large.

The terminal 220 may be electrically connected to both ends of the conductor 210 and may transmit power received from the outside to the conductor 210. For example, the terminals 220 may be arranged to pass through the inside and outside of the space 250.

The volume of the space 250 can be expanded by generating heat according to the power supply of the conductor 210 in a heated state, and on the contrary, the space 250 when not electrically connected can be configured to shrink.
