Description

  The present invention relates to a conductive structure, and more particularly, to a conductive structure of an electrostimulator having excellent conductivity and stability in the design of the conductive structure of the electrostimulator.

  Known electric stimulators (for example, TENS, EMS, etc.) have the effect of exercising physical fitness by exercising muscles by transcutaneously contracting a low frequency pulse. Regarding the conductive technique of the low-frequency pulse device used in the known muscle training / exercise field, as shown in FIGS. 1 and 2, the conductive structure 90 of the electrical stimulator includes a plurality of electrode sheets 91. A conductive wire 92 is extended on the electrode sheet 91. The conductive wire 92 is a flexible base sheet body such as polyimide (PI) or polyethylene terephthalate (PET). A conductive layer 921 (for example, a conductive material such as silver paste) is applied to one surface of the conductive wire 92, and the other surface of the conductive wire 92 facing the conductive layer 921 forms an insulating surface (insulating layer) 922. The edge of the flexible wire 92 forms a conductive connection end 923, and the conductive connection end 923 is provided with a conductive through hole 924. Further, a conductive contact 931 is provided at an appropriate place on the bottom surface of the electric circuit board 93. The conductive contact 931 forms, for example, a sheet body of a copper foil layer, and corresponds to the positioning hole 932 of the electric circuit board 93. When combined and fixed, as shown in FIG. 2, the conductive wire 92 is extended below the electric circuit board 93 to bring the conductive connection end 923 of the conductive layer 921 into contact with the conductive contact 931 of the electric circuit board 93, and then to continue. The bolt 94 is passed through the conductive through hole 924 and the positioning hole 932, and is screwed and fixed to complete the electrical connection between the electrode sheet 91 and the electric circuit board 93.

  The electrically conductive structure 90 of the electrostimulator described above can achieve a combination of electrical connection and fixation, however, a drawback remains. As an example, the grounding of the conductive layer 921 (for example, silver paste) of the conductive wire 92 is costly and manufacturing time consuming if the grounding is not applied only to the surface. Further, the conductive wire 92 itself cannot be twisted and folded. In this way, the electrical connection position is limited, and if the conductive contact 931 is provided above the electric circuit board 93 as shown in FIG. 2, the conductive layer 921 of the conductive wire 92 contacts the conductive contact 931. However, it cannot be electrically connected and fixed, and the flexibility of installing electronic elements on the electric circuit board 93 is greatly limited, which is not ideal. Furthermore, when the conductive connection end 923 of the conductive wire 92 is fastened and fixed, if the amount of tightening force is not appropriate or an excessive amount of tensile force is applied, the conductive layer 921 will be destroyed, and the product will not malfunction or function due to poor contact. Cause a phenomenon. This point also needs to be improved. Therefore, it is an important direction for those skilled in the art to improve the technique of the conductive structure of the known electrostimulator and the above-mentioned drawbacks.
