Structure of connection pin in electrical connector

A structure for a connection pin in an electrical connector (100), the electrical connector including a connector housing (110) and at least one connection pin (130), the connector housing including a mating part (116) for the connection pin, each connection pin is adapted for mating with a mating part in the connector housing and is characterized by a first electrical contact (132) for mating with a complementary electrical contact of a mating connector, a second electrical contact (134) for electrical connection to a corresponding contact on a printed circuit board (200), and a curved portion (136) which connects the first electrical contact with the second electrical contact at respective first and second rounded bends in the connection pin (130), wherein the first and second electrical contact extend longitudinally parallel to each other, the curved portion curves laterally from a rear end of the first electrical contact and longitudinally and rearwardly terminating at the second electrical contact, the first and second rounded bends in the connection pin having a bend radius-axes-parallel to each other and perpendicular to the longitudinal extension of the first and second electrical contacts, wherein the second electrical contact (134) is formed so as to be parallel with the first electrical contact (132), and

• wherein the mating part (116) in the connector housing comprises a front mating groove (116a) for securing the first electrical contact therein and a rear mating groove (116b) for securing the curved portion and the second electrical contact therein.
