Abstract
The invention relates to a contact pin, comprising an angular end section, which is in particular designed for connecting to a wire or plug, wherein the angular end section has an angular cross-section. According to the invention, the contact pin has a round end section that is opposite the angular end section and that is designed for soldering to a circuit board. The round end section has a cross-section that is round at least in some sections of the circumference.
Claims20
A contact pin (1, 2) having an angular end section (3) that is configured for connecting to a wire or plug, wherein the angular end section (3) has an angular cross-section, and
- the contact pin (1, 2) has a round end section (7, 8, 11, 12) that lies opposite the angular end section (3) and is configured to be soldered to a circuit board (20), wherein a cross-section of the round end section is embodied in a circular manner at least in sections of a periphery,
- wherein the contact pin (1, 2) is formed from a raw wire with an angular cross-section, wherein the angular end section (3) corresponds to the angular cross-section of the raw wire and the round end section (7, 8, 11, 12) is re-shaped from an angular end section of the raw wire.
A method for connecting a contact pin (1, 2) to a circuit board (20), the method comprising:
- providing a raw wire with an angular cross-section;
- forming the contact pin from the raw wire, wherein an angular end section (3) of the contact pin corresponds to the angular cross-section of the raw wire;
- forming a re-shaped round end section (7, 8, 11, 12) of the contact pin that lies opposite the angular end section (3) by re-shaping the angular cross-section of the raw wire so that the re-shaped round end section of the contact pin has a circular cross-section at least on one peripheral section;
- inserting the re-shaped round end section (7, 8, 11, 12) into an aperture (25) of the circuit board (20);
- and
- soldering the re-shaped round end section into said aperture.
