Abstract
A connection structure includes at least one yarn wire, a back adhesive, and a circuit board. The yarn wire includes a yarn and a metal wire that are helically twisted. The back adhesive is elastic and is in an adhesive gel state when coming in contact with heat. A through hole is formed on the circuit board, and a diameter of the through hole D, a diameter of the yarn wire d, a shrunken diameter of the yarn wire being stretched dmin, and a jig thickness t of a jig have a relation of: 2d>D>2dmin+t. During assembly, the yarn wire is aligned with the through hole of the circuit board. A portion of the yarn wire is extruded into and passes through the through hole by using the jig, and the portion of the yarn wire forms a protruding wire segment.
Claims10
A connection structure, comprising:
- at least one yarn wire;
- a back adhesive;
- and
- a circuit board having at least one through hole penetrating through two opposite sides of the circuit board, wherein a diameter of the through hole is defined as D, a diameter of the at least one yarn wire is defined as d, a shrunken diameter of the yarn wire being stretched is defined as dmin, and a jig thickness of a jig is defined as t;
- wherein the diameter of the through hole, the diameter of the at least one yarn wire, the shrunken diameter of the yarn wire being stretched, and the jig thickness have a relation of:
- 2d>D>2dmin+t;
- wherein the yarn wire is arranged on the back adhesive so that the back adhesive is disposed on one side of the yarn wire, and the yarn wire is aligned with the through hole of the circuit board;
- wherein a portion of the yarn wire is extruded into and passes through the through hole by using the jig, and the portion of the yarn wire that passes through the through hole forms a protruding wire segment that is expanded and is in a shape of a round loop;
- wherein a fixing back adhesive is adhered to one side of the circuit board, and the fixing back adhesive is adhered to the circuit board and the protruding wire segment so that the yarn wire and the circuit board are connected and fixed to each other.
