Abstract
A connecting pin for an electronic circuit board electrically connects a lead of a component to be surface-mounted to the electronic circuit board to a coating layer on an inner wall of a through-hole of the electronic circuit board. The connecting pin includes a cylindrical body formed of an electrically conductive metal, which is inserted into the through-hole of the electronic circuit board. The lead of the component is press-fitted, and inner surface of the cylindrical body is provided with a plurality of small protrusions deformable when contacting protrusions of the press-fitted lead.

A connecting pin for an electronic circuit board, wherein the connecting pin electrically connects a lead of a component that is to be surface-mounted to the electronic circuit board to a coating layer on an inner wall of a through-hole of the electronic circuit board, the connecting pin including:
- a cylindrical body formed of an electrically conductive metal and inserted into the through-hole of the electronic circuit board,
- wherein the lead of the component is press-fitted, and an inner surface of the cylindrical body is provided with a plurality of small protrusions deformable in the shape when contacting protrusions of the press-fitted lead,
- wherein the small protrusions on the inner surface of the cylindrical body comprise knurling protrusions which are spaced apart in an interval on the inner surface of the cylindrical body, and
- wherein the knurling protrusions are tilted at an angle (θ) ranging from 25° to 65° along the inner surface of the cylindrical body with respect to an insertion direction of the lead.
