An connector (1) includes an insulative housing (2), and a multiplicity of conductive contacts (3) received in the housing. The housing comprises a mating surface (20) and a mounting surface (21) opposite to the mating surface. The housing defines a plurality of passageways (23) extending vertically therethrough to receive corresponding contacts therein. A seriate stand-offs (24) extends from the two opposite lateral sides of the adjacent passageways on the mounting surface.

Method for preventing solder from rising to a portion of an electric contact when the electric contact is being soldered to a copper foil so as to extend therefrom. The portion is plated with a noble metal and adapted to contact a mating object. Cooling means is brought into contact with at least the portion of the electric contact adapted to contact the mating object, and connection portion between the electric contact and the copper foil is heated by heating means. The rising of solder can be prevented and the electric contacts thus obtained are superior in mechanical property (sufficient bonding strength), electrical property (conductive property and low contact resistance), resistance to environmental conditions (impediment to oxidization), and physical property (limitation of rise of solder due to capillary action).

A male contact having a longitudinal axis includes a head configured to contact a corresponding electrical contact and a first portion extending along the longitudinal axis and configured to be received within a socket of a corresponding terminal assembly. The first portion comprises resilient members extending axially from the head, the resilient members defining an interior cavity within the male contact, at least one of the resilient members having an arcuate inner surface in parallel with the longitudinal axis of the corresponding male contact.
