Abstract: An electric contact plug receives a tip jack input at a plug-in zone, and completes the electrical connection via a connection zone to an electronic component, such as a printed circuit board. The electric contact plug also includes an intermediate zone, connected between the plug-in zone and the connection zone.

Thus, the inventive electric contact plug avoids the problems of friction and corrosion within the plug-in zone. Moreover, this electric contact plug is compatible with thick-wire bonding, and can be manufactured economically.
