Description

An electrical wire of elasticity type cable

The present invention relates to a wire cable, and more particularly, to a wire cable capable of restoring the wire cable to a predetermined length so that the wire cable can be restored to a predetermined length, .

Generally, the wire has a structure in which a copper wire is used as a core and an outer portion of the core is covered with an insulator.

Most of these wires are not stretchable, but exceptionally elastic wires are curled cords used in telephones and the like.

However, such a curl cord is thick and heavy and can not be utilized in various ways. When the stretchability is repeated for a long period of time, the curl cord is stretched and neatly arranged, so that the curl cord is not good in appearance and inconvenient to use.

Since the copper wire used as the core has ductility due to the characteristics of copper, it is tensioned when an external force is applied, but does not contract again, and the ductility of copper is very small.

And the coating that insulates the copper wire is also excellent in flexibility and is stretched by external force but does not contract like copper wire.

As described above, although the wire by the copper wire and the coating is flexible, since there is no elastic restoring force, when the external force is applied to the wire, it is stretched only and is not restored to the initial length state because it is not contracted.

Therefore, in order to use the wire where the displacement of the length exists, the wire had to be long as the displacement of the expected length.

In addition, such long wires are entangled with each other to damage the coated copper wire, disadvantages such as disconnection, and poor appearance, which is not suitable for devices and environments where appearance design is important.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned disadvantages, and it is an object of the present invention to provide an electric cable capable of restoring the wire cable to an original state, Capable wire cable.

In order to achieve the above object, the present invention provides a telescopic cable having a cover made of an elastic material capable of shrinking and expanding, a conductor wire fixedly wired so as to have an allowable stretchable length that is bent on one surface of the jacket, And connectors provided at both side ends of the wired cloth.

A stretchable wire cable for attaining the object of the present invention is a stretchable wire cable comprising a cover made of a plate-like rubber strand having a predetermined length capable of shrinking and expanding, a lead wire inserted into the inside of the cover, And is characterized in that a conductor is interposed between a plurality of rubber lines and then subjected to compression bonding.

The stretchable wire cable of the present invention has the following effects.

First, since it is made only of conductor and elastic body, it is simple in structure, easy to manufacture, and has an elastic restoring force, so that the wire length is elongated and elongated by external force, and can be restored to the original length.

Second, by forming a conductor including a Kevlar in an enamel-coated conductor, the conductor does not break off, and even if it overlaps with each other, no short circuit occurs.

1 and 2, a stretchable wire cable 100 according to an embodiment of the present invention includes a cover 10 made of an elastic material capable of shrinking and expanding, And a lead wire (20) fixedly wired so as to have a stretchable margin length.

The stretchable wire cable 100 of the present invention can be adjusted in its length by being stretched or contracted through its own elasticity and flexibility. In the state where no external force is applied, the wire 20 can be stretched, When the tensile force is applied along the longitudinal direction, the cover 10 is expanded and contracted by the self-elastic force, as shown in FIG. 2, while the wire 20 is unfolded, ) Is longer than the total length of the first and second plates.

Hereinafter, each component of the telescopic cable according to the present invention will be described in detail.

The cover (10) is made of an elastic material capable of shrinking and expanding, expanding when an external force is applied, and restoring the original state when the external force is lost.

In this embodiment, the covering 10 is in the form of a flat rubber band of a certain length, and is preferably made of a stretchable fabric, such as a bra strap.

As described above, the conductive wire 20 should be configured to be long when an external force is applied. Since the conductive wire 20 is difficult to be made of a material capable of shrinking and expanding like a covering 10 due to its electrical conductivity, do.

The wire 20 is wired on one side of the cloth 10 and is bent in a wavy shape and the wire 20 to be wired through the sewing is fixed to the cloth 10.

The bent portion of the lead wire 20 provides an allowance length that can be made longer when an external force is applied.

Then, the upper and lower portions of the lead wire 20 are fixed to the cover 10 in such a manner as to hold them from both sides by sewing, so that the original can be maintained even when the cover 10 is pulled and pulled. Therefore, it is possible to prevent the lead wire from being broken by the tensile force, and to prevent the lead wire from being detached from the cover 10. [

Furthermore, the cable 20 is embedded in the cable 20 to enhance the tensile strength, thereby preventing the cable 20 from being broken.

Kevlar is the name of an aramid fiber developed by DuPont. It has excellent tensile strength, toughness and heat resistance, and has high strength and high elasticity.

In addition, the surface of the lead wire 20 is coated with enamel to prevent the occurrence of a short circuit even if the wires are overlapped with each other.

The connector 30 is connected to both ends of the sheath 10 on which the lead wire 20 is wired.

Here, the connector 30 may be provided in various shapes, such as a pin shape and a pin shape, depending on the applicable equipment to which the electric cable 100 is connected.

For example, when the connector 30 is in the form of a plug, the ends of the wire 20 wired to the jacket 10 are connected by soldering, and then connected to the jacket 10 to be fixed with a rivet or the like.

Structural features of the coating 10 and the conductor 20 will be described below.

The cover 10 may be formed of a band having a predetermined length, and the wire 20 is fixedly installed on one surface of the cover 10 so as to be exposed to the outside. At this time, the outer surface of the lead wire 20 is enamel coated and may be exposed to the outside.

The operation of the stretchable wire cable according to the present invention constructed as described above is as follows.
