Contact for surface mounted connector

An electrical connector for connecting a printed circuit board with an IC card, comprising:

• an insulative housing having a top surface, a bottom surface, a pair of sidewalls, a plurality of passageways arranged along the length of the housing, and a pair of spindles longitudinally extending along the length of the housing and intersecting each passageway;
• and
• a plurality of terminals received in corresponding passageways, each terminal including a base slightly protruding below the bottom surface of the housing for being connected to the printed circuit board, a fitting tail projecting from an end of the base and being secured to the sidewall, an annular beam connected to an opposite end of the base and moveably supported by the spindle, and a spring beam extending from the annular beam and protruding from the top surface of the housing for engaging with the IC card, said spring beam having a free end abutting against the sidewall for ensuring uniform normal forces exerted by the terminals against the IC card placed parallel to the top surface of the housing;
• wherein the base defines a mounting surface at a bottom thereof for mounting the connector to a circuit board;
• wherein the fitting tails are disposed parallel to the bases to ensure the coplanarity between the mounting surfaces and the circuit board;
• wherein the spring beam includes an inclined portion connecting to the annular beam, a convex portion extending beyond the top surface of the housing, and a retaining portion located at the free end of the spring beam;
• wherein each sidewall is step-shaped and provides a lower surface and an upper surface at a lower end thereof, and wherein the fitting tail is mounted to the lower surface and the retaining portion presses upwardly against the upper surface.
