A modular jack connector includes a housing defining a first direction and a second direction perpendicular to the first direction. A plurality of terminals are disposed in the housing. Each terminal having a body portion and a contact end portion connected to the body portion. Each contact end has a contact surface facing the first direction for connecting to a counterpart connector. The contact surface is a rolled surface of a metal sheet from which the contact terminals are formed. Plating process becomes more efficient and plating quality is improved, resulting in terminals with high contact surface quality being made for better electrical connectivity when connected to counterpart connectors.
