A connecting structure of a
spinning wire and a circuit board comprises at least one
spinning wire, gum and the circuit board. The
spinning wire comprises a spinning
yarn and a
metal wire, and the back glue can be combined with the spinning wire. A through hole is formed in a circuit board, and the
diameter D of the through hole, the wire
diameter d of a spinning wire, the wire
diameter dmin after the spinning wire is stretched and contracted and the thickness t of the jig meet the following relational expression: 2dgt; dgt; 2dmin + t. During
assembly, the spinning wire with gum can be aligned with the through hole of the circuit board, the part of the spinning wire is squeezed into and penetrates through the through hole by a jig, the part, penetrating through the through hole, of the spinning wire forms an expanded round-hole-shaped protruding
line segment, the spinning wire can generate
friction force and forward pushing force on the inner wall of the periphery of the through hole, and the expanded protruding
line segment is not prone to deformation. The spinning guide line can be prevented from retreating along with the jig. And the fixing back
adhesive is adhered to the circuit board and the protruding line segments. The spinning lead and the circuit board can be connected, fixed and conducted,
soldering tin is not needed, and
environmental protection is achieved.
