Abstract

Disclosed is a multi-directional conductive structure. The multi-directional conductive structure comprises: a flexible member; a conductor forming conductivity by being diagonally winding in the lengthwise direction of the member; and a flexible structure. Since the conductor is formed by secondarily winding around the flexible structure, the conductor has a double flexible structure, and is configured to be possible to be flexible in all three axes at the same time. Therefore, the conductor can be flexible in three axes, thereby preventing a short circuit, maximizing a heating area and a bending degree by the conductor, and enlarging heat distribution.

Description

[0001] The present invention relates to a multi-directional electrically conductive structure,

The present invention relates to a multi-directional conductive structural body, and more particularly, to a multi-directional conductive structural body which comprises a conductive body formed by winding a conductive member in an oblique direction on an outer surface of a member capable of expansion and contraction to form a three- To a multi-directional conductive structure capable of expanding and contracting a conductor in three axial directions.

Generally, a conductive wire is manufactured by coating or coating an insulating resin layer on the outside of a copper wire, and it is not only a wire having a relatively large diameter and ductility but also being heavy, Or as a heating line.

On the other hand, such items as smart clothes detect the external stimuli in the clothes themselves and apply various signal transmission techniques to the clothes to respond to the set conditions by themselves, and incorporate various digital devices, so that they can transmit current and electric signals, A conductive wire capable of securing a comfortable feeling is required.

In accordance with this demand, a conductive wire manufactured by plating a conductive metal such as copper (Cu) has recently been commercialized. However, since the conductive wire is plated on a fiber yarn, the diameter of the wire is smaller than that of a conventional wire, However, such a conductive wire can not secure stable conductivity because the plating layer is peeled or damaged by a needle or the like when an external force or a frictional force is applied during use or when a woven fabric is woven by a loom. In particular, when a tensile force is applied to the fiber yarn while the plated wire is woven in a planar body, the amount of the internal fiber yarn is increased to some extent, 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 it is very vulnerable to tensile force acting in the longitudinal direction, Sufficient durability can not be ensured, the material thereof is expensive, and the manufacturing cost is very high, so that the practical application is impossible.

Also, since the external load is directly applied to the internal conductor when an external force such as load, impact force, frictional force or the like is externally applied to the conductors, if the external conductor is repeatedly exposed to an external force, breakdown of the conductive wire, damage to the conductive wire, There is a limit in that sufficient durability can not be secured.

In particular, when the conventional conductor is arranged to be exposed externally to a fabric such as a fabric, the external load is directly applied, so that the conductor is easily damaged in a short time and the energy efficiency is remarkably deteriorated due to the sudden release of heat have.

Therefore, it is necessary to develop a conductor 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.

A multi-directional conductive structure according to an embodiment of the present invention includes: a structure having elasticity in at least one axial direction; A member wound around the structure along the longitudinal direction of the structure and having elasticity in at least one axial direction; And a conductive member wound around the member along the longitudinal direction of the member and having a conductive property.

The diameter of the structure may be greater than the diameter of the member.

The member may be continuously wound in an oblique direction having a constant inclination with respect to the longitudinal direction of the structure.

According to the present invention, it is possible to prevent a problem that a conductor is short-circuited by an external impact by providing the conductor structure in a stretchable and contractible manner in three axial directions. That is, the durability of the heating element can be improved.

Further, by the double winding structure, it is possible to secure an internal convection space which can not be realized in the conventional planar surface heating element, thereby improving the warmth and ensuring excellent thermal quality.

Further, it has an advantage that it can be utilized for various kinds of warm products by a simple manufacturing method.

Referring to FIGS. 1 to 3, the multi-directional conductive structure 100 according to one embodiment may have elasticity and conductivity in three axial directions. The multi-directional conductive structure 100 may include a stretchable conductor 30 and a structure 40.

The stretchable conductor 30 can have stretchability and conductivity in at least one axial direction. The stretchable conductor 30 may include a member 20 and a conductor 10 surrounding the member 20.

The member 20 may have elasticity in at least one axial direction. The member 20 may have elasticity in the longitudinal direction. For example, the member 20 may be an elastic material such as rubber, silicone, or sponge. The member 20 may have a cylindrical shape. However, this is only one example, and it should be noted that the shape of the member 20 is not limited in the present invention.

The conductor (10) can be wrapped around the outer surface of the member (20). The conductor (10) may be wrapped around the member (20) in an oblique direction. The conductor 10 may be continuously wrapped in a diagonal direction having a constant inclination with respect to the longitudinal direction of the member 20. However, the arrangement of the conductors 10 is not necessarily limited to the above.

According to the above structure, the stretchable conductor 30 can have conductivity and stretchability.

Specifically, since the stretchable conductor 30 includes the conductor 10 having conductivity, it can be understood that the stretchable conductor 30 has conductivity.

In addition, even when the conductor 10 does not have elasticity, the conductor 10 can secure an allowable length that can be stretched around the member 20 having elasticity. Accordingly, when the member 20 is stretched in the longitudinal direction, the conductor 10 can be stretched by an allowable length. In other words, the stretchable conductor 30 may have elasticity in at least one axial direction. The structure 40 may have elasticity in at least one axial direction. The structure 40 may have elasticity in the longitudinal direction. For example, the structure 40 may be an elastic material such as rubber, silicone, or sponge. The structure 40 may have a cylindrical shape. However, this is only an example, and it should be noted that the shape of the structure 40 is not limited in the present invention.

The structure (40) may be larger than the member (20). When the structure 40 and the member 20 are cylindrical, the diameter of the structure 40 may be greater than the diameter of the member 20.

On the outer surface of the structure 40, the stretchable conductor 30 can be wrapped. The stretchable conductors 30 may be continuously wrapped in a diagonal direction having a constant inclination with respect to the longitudinal direction of the structure 40. [ However, the arrangement of the stretchable conductors 30 is not necessarily limited to the above.

According to the above structure, the multi-directional conductive structural body 100 can have elasticity and conductivity in three axial directions or more.

Specifically, since the multi-directional conductive structure 100 includes the conductive material 10 having conductivity, it can be understood that the multi-directional conductive structure 100 has conductivity.

The multi-directional conductive structure 100 may have two stretchability in the longitudinal direction (first axis direction). The stretchable conductor 30 can be wound around the structure 40 to secure an allowable length. Accordingly, when the structure 40 is elongated in the longitudinal direction, the stretchable conductor 30 can be stretched by a predetermined length. Furthermore, when the structure 40 is elongated beyond the allowable length, it can be further stretched due to the stretchability of the stretchable conductor 30 itself described above. Accordingly, the multi-directional conductive structure 100 may have two stretchability in the longitudinal direction (first axis direction).

The multi-directional conductive structure 100 may have elasticity in a width direction (second axis direction) intersecting with the longitudinal direction. When the structure 40 is stretched in the width direction, the stretchable conductor 30 can be stretched due to its own stretchability. Therefore, the multi-directional conductive structure 100 may have elasticity in the width direction (second axis direction).

Likewise, the multi-directional conductive structure 100 may have elasticity in a thickness direction (third axis direction) that intersects the longitudinal direction and the width direction. When the structure 40 is stretched in the thickness direction, the stretchable conductor 30 can be stretched due to its own elasticity. Accordingly, the multi-directional conductive structure 100 may have elasticity in the thickness direction (the third axis direction).

In the same principle, the multi-directional conductive structure 100 may be expanded and contracted simultaneously in the width direction and the thickness direction.

In short, by arranging the longitudinal direction of the structure 40 and the longitudinal direction of the member 20 differently, it is possible to expand and contract in three axial directions.

Further, since expansion and contraction of the three axes is possible, short-circuiting can be prevented and durability can be improved.

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

4 is a side view showing that the flexible conductor according to one embodiment is wound in an oblique line in the longitudinal direction of the structure.

Referring to FIG. 4, the flexible conductor 30 may be wrapped around the structure 40 in an oblique direction. The structure 40 is configured to be larger than the size of the member 20, and may be a cylindrical shape.

The elongate conductor 30 is surrounded and formed around the outer periphery of the structure 40 so that three axes of X, Y and Z axes can be expanded and contracted.

The double elongated and contracted structures in the left and right direction and the vertical direction of the structure 40 and the vertical and lateral directions of the member 20 are transmitted to the conductor 10, It is possible to expand and contract in three axes.

According to the present invention, it is possible to prevent a problem that a conductor is short-circuited by an external impact by providing the conductor structure in a stretchable and contractible manner in three axial directions. That is, the durability of the heating element can be improved. Further, by the double winding structure, it is possible to secure an internal convection space which can not be realized in the conventional planar surface heating element, thereby improving the warmth and ensuring excellent thermal quality. Further, it has an advantage that it can be utilized for various kinds of warm products by a simple manufacturing method.
