Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 2 to 9B, and the same reference numerals are given to the same constituent elements in FIGS. 2 to 9B. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

FIG. 2 is a process diagram for explaining a method of manufacturing a fiber-based conductor wire having a connection terminal according to the first embodiment of the present invention, and FIGS. FIG. 3A is a view showing that the cross-sectional structure of the conductive wire body is a round-bar-shaped structure, FIG. 3B is a cross-sectional view of the conductive wire body, And the structure is a cylindrical structure.

2 to 3B, a method of manufacturing a fiber-based conductor wire having a connection terminal according to a first embodiment of the present invention includes a conductive yarn 11 having conductivity and a fiber yarn 12 (an organic fiber yarn and an inorganic fiber yarn (S1) for fabricating a conductive wire body 1a of a linear member shape using a conductive wire insulation process (s1) which electrically insulates a conductive portion except for the connection terminal formation portion (s2) is performed. In the conductive line insulating step (s2), the insulating layer 13 is formed on the conductive material 11 except for the connecting terminal forming part before the conductive line body forming step (s1).

The conductive line body fabricating step s1 includes a conductive line constraining step s11 for forming a conductive line constraining section a in which the conductive material 11 and the fiber yarn 12 are integrally constrained by a winding or weaving method, A step of exposing the conductive yarn 11 to the outside without selectively binding the conductive yarn 11 to the fiber yarn 12 in the execution of the conductive constraining step s11 so that the conductive yarn exposure section b for forming the connection terminal is formed s12. The conductive arresting step and the conductive agent exposing step can be performed by controlling the operations of the cable forming part 110, the cable withdrawing part 130, and the like of the manufacturing apparatus shown in FIGS. 4A and 4B, .

The step of exposing the protector (s12) is a step of forming a protector exposure section (b) for each desired interval in the execution of the step of constraining the conductor (s11). The protector exposure step (s12) (B) is repeatedly formed as shown in FIG.

The conductive constraining step s11 includes a supplying step of supplying the conductive yarn 11 and the fiber yarn 12, a weaving step in which the conductive yarn and the fiber yarn supplied through the supplying step are formed into a linear member, And then pulling out the linear member formed by laminating the wire member to form a conductive member in the 'a' region of the fiber-based conductor wire of the long linear member.

The conductive constraint section (a) is a section that can be formed by simultaneously performing the supplying process, the weaving process, and the drawing process. That is, the conductive yarn 11 and the fiber yarn 12, which can be woven through the weaving process, It is necessary to carry out the feeding process so as to be supplied, and at the same time, take out the woven portion by the weaving process and draw out the woven portion so that the continuous weaving process is performed.

Meanwhile, in the step of exposing the protector (s12), only the supplying process and the taking-out process are performed without performing the weaving process in a specific section so that the conductive yarn 11 is exposed to the outside without being woven into the fiber yarn 12. [ In other words, the step of exposing the protector (s12) does not perform the weaving process because the protector 11 should not be woven into the fiber yarn 12, but the supply step for supplying the electrically conductive yarn exposed to the outside in the protector exposure period (b) And the withdrawal process is simultaneously performed because the exposed portion (b) of the conductive agent exposed to the outside through the supplying process must be pulled out.

In the conductive line insulating step s2, the insulating layer 13 is formed on the outer surface of the conductive material 11 except for the portion of the conductive material exposed b, among the conductive materials 11 forming the conductive wire body 1a. The insulation layer formation process is performed by calculating the interval and the formation length of the exposure section (b). The insulating layer forming process is performed before the conductive line body fabrication step (s1), so that the conductive section (insulation section) having the insulation layer is disposed in the conductive constraint section (a) and the conductive section Insulation section) is placed in the protector exposure section (b). At this time, the insulating layer 13 is composed of an insulating coating layer 13a formed in the form of a thin film on the outer surface of the conductive yarn formed by copper wire or the like as will be described later in detail.

For example, the conductive material may be selected from the group consisting of metal yarn formed of conductive metal, carbon yarn, conductive material (conductive metal nano- Metal oxide particles, graphene, and the like), fiber yarn coated with a conductive material, or the like can be applied, but a conductive metal yarn formed of stainless steel, titanium, copper (Cu), or the like can be typically applied.

It is preferable that the protector 11 has a diameter in the range of 10 to 500 micrometers (m) so as to be woven or sewn on cloth or the like by supplying the weft after weaving and weaving to the weaving machine in a state of being made of fiber- More specifically, the conductive metal sheet of the diameter range described above is used as the conductive sheet 11 because at least one conductive metal sheet is included and the total diameter of the conductive metal sheet is 1000 micrometers (탆) (Mu m) or more, and conductive metal yarns of 10 micrometers or less (micrometers) or less can not be mass-produced by current production techniques This is because it is difficult to conduct actual verification due to difficulties in production. In this embodiment, a copper wire or stainless wire having a diameter in the range of 20 to 100 micrometers (탆), which is proven in terms of conductivity and durability, is applied.

On the other hand, the insulating coating layer 13a is a layer formed on the outer surface of the conductive material 11 for electrical insulation and formed of an insulating material having an insulating property and melting at a relatively low temperature and having a melting point do.

For this purpose, the insulating coating layer 13a may be formed of an insulating material having a melting point in the range of 120 to 280 占 폚. For example, the insulating material may be a varnish selected from polyurethane, polyamide, polyester, polyvinyl butyral, polyester imide and polyimide resin, but in this embodiment, it is melted at about 240 캜 and satisfies sufficient flexibility , It is formed of an enamel resin (varnish is mixed with varnish) using polyurethane varnish whose heat resistance grade is E to F and heat resistance index is 120 to 155 ° C.

In this case, the insulating coating layer 13a may be formed by supplying the fiber-based lead wire 1 to a loom for integrally arranging the fiber-based lead wire 1, supplying it to an embroidery machine for embroidery arrangement, sewing the needle It is important to be formed to have an optimum thickness with sufficient flexibility in the placement process. A sample having an insulating coating layer formed on a conductive metal sheet in various thicknesses was prepared by taking into consideration the characteristics required for the operation of the insulating coating layer 13a. As a result, it was found that the thickness of the insulating coating layer 13a was 0.0010 To 0.0150 mm (1 to 15 micrometers (占 퐉)), it is possible to secure stable insulation, flexibility and durability. More specifically, the experimental results are as follows. A vibration-proof test apparatus in which a fiber-based conductor wire having an insulating coating layer formed to a thickness of 0.0150 mm or more on a conductive metal sheet having a diameter of 10 to 500 micrometers (m) And it is confirmed that cracks are generated in the insulating coating layer when the number of oscillations is 10,000 times or more on the average. Further, it was found that the thinner the thickness of the insulating coating layer, the better the brittleness due to the absence of cracks. The thickness of the insulating coating layer was 0.0010 mm or less, No substantive verification was possible.

Based on the experimental results, the thickness of the insulating coating layer 13a in this embodiment is formed to be in the range of 0.0010 to 0.0150 mm, which is a thickness range that not only satisfies flexibility but can be manufactured, and has brittleness, , And the conductive material 11 at this time applies a copper wire having a diameter in the range of 10 to 500 micrometers (占 퐉).
