DETAILED DESCRIPTION

[0025] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments. The present invention can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided so that this disclosure will be thorough and complete, and the concept of the present invention will be fully conveyed to those skilled in the art, and the present invention will only be limited by the claims.

[0026] The present invention discloses a method for fixing a conductive line on a flexible material, which comprises the following three parts:

[0027] 1. Conductive Wire

[0028] The conductive wire 1 of the present invention preferably adopts Teflon conductive wire, which has a thin outer skin and contains more than 30 thin copper wires inside. The wire is fine in size, resistant to high temperatures above 260 degrees, resistant to bending and corrosion, has strong insulation, low friction coefficient and good flexibility.

[0029] The conductive thread 1 is sewn on the flexible material 2 by cross stitching. Figure 1 As shown, when the conductive thread 1 is sewn, the needle movement effect is a cross fold line. When the fabric is stretched, the conductive thread 1 gradually changes from a cross fold line to a straight edge. The cross needle movement method is suitable for the expansion and contraction characteristics of the flexible material 2.

[0030] The flexible material 2 can be selected as knitted products such as knitted protective gear and yoga pants, or can be selected as fabric products such as linen, polyester, nylon, etc.

[0031] 2. Conductive wire and electrode connection

[0032] like Figure 2 and 4 As shown, the conductive wire stripping head, electrode and nickel-plated cloth are connected, and the hot-pressed TPU is isolated from the outside world. The specific structure is:

[0033] The stripping position of the conductive wire 1 is sandwiched between the first nickel-copper cloth 3 located above and the second nickel-copper cloth 9 located below. The second nickel-copper cloth 9 is fixed to the flexible material 2 by an adhesive 13. A sponge 4 is provided above the first nickel-copper cloth 3. A conductive carbon film 5 is provided above the sponge 4 and covers the sponge 4 and extends beyond the edge of the first nickel-copper cloth 3. The conductive carbon film 5 is bonded and fixed to the structure below by an adhesive 13. The sponge 4 is provided above the first nickel-copper cloth 3 and is staggered from the position of the conductive wire 1. The conductive carbon film 5 is fixed to the flexible material 2 or the conductive wire 1 by an adhesive 13 at a position beyond the edge of the first nickel-copper cloth 3.

[0034] The conductive carbon film 5 is composed of PU sheets and carbon molecules, forming a material that can conduct electricity on both sides. The sponge 4 is added under the conductive carbon film 5 to form a convex bulge, which can more effectively fit the skin, reduce the foreign body sensation, and conduct the current.

[0035] Nickel copper cloth is a highly metallized nylon or polyester material substrate with excellent conductivity equivalent to metal, with a resistance of a few tenths of an ohm per square. It also has good toughness and winding properties. Pasting it under the conductive carbon film 5 can make the conductive carbon film 5 have a smaller resistance and a more uniform resistance. The edge of the nickel copper cloth should cover the unpeeled position of the wire, and the copper wire should not be exposed.

[0036] The adhesive 13 is preferably a waterproof hot melt adhesive.

[0037] 3. Connect the conductive thread and button

[0038] like Figure 3 and 5 As shown, the button, the conductive wire stripping head and the nickel-plated cloth are connected, and the hot-pressed TPU is isolated from the outside world. The button is usually assembled with the host to achieve the functionality of the entire equipment. According to the structure of the host interface, the shape and number of the button are reasonably designed. For example, the button can be set to one or more, round or square, etc., and the shape matches the host interface structure.

[0039] The specific structure is:

[0040] The button includes a button female seat 7 and a button male seat 6. The button female seat 7 penetrates the flexible material 2, and the button male seat 6 is sleeved on the front of the button female seat 7;

[0041] A third nickel-copper cloth 10 is provided between the back side of the flexible material 2 and the button mother seat 7. The third nickel-copper cloth 10 penetrates through the back side of the button mother seat 7 and is fixed to the back side of the flexible material 2 by means of an adhesive 13;

[0042] A fourth nickel-copper cloth 11 is provided below the button seat 7, and the stripping position of the conductive wire 1 is located between the button seat 7 and the fourth nickel-copper cloth 11. The other side of the fourth nickel-copper cloth 11 is fixed to the shielding layer 12 by an adhesive 13. The shielding layer 12 is used to prevent the adhesive from being exposed.

[0043] A connecting fixing sheet 8 is provided between the button male seat 6 and the flexible material 2. The connecting fixing sheet 8 passes through the front of the button female seat 7 and is fixed to the front of the flexible material 2 through an adhesive 13. The design of the connecting fixing sheet 8 can fix the flexible material 2 to ensure that the button does not come loose. Because the flexible material 2 is flexible, if it is directly buckled without the connecting fixing sheet 8, the flexible material 2 is easily pulled out by pulling hard, and the button will fall off.

[0044] The adhesive 13 is preferably a waterproof hot melt adhesive.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
