ABSTRACT:
An electrical connector comprises a dielectric base defining a number of contact receiving slots therein, a slidable cover fixed to the base and defining a number of pin receiving holes for receiving corresponding pins of an IC package therein, and a number of contacts received in the corresponding contact receiving slots of the base. Each contact comprises a U-shaped, non-symmetrical guiding portion for guiding a corresponding pin of the IC package to electrically connect with the contact, a contact portion comprising a pair of contact tabs extending from free ends of the guiding portion and defining a gap for engaging the corresponding pin of the IC package, a main body connected to the guiding portion for supporting the contact, and a solder pad extending from a lower edge of the main body for being surface mounted to a circuit board. The guiding portion forms a coined convex collar section on an upper edge between which the corresponding pin of the IC package is inserted into a collar chamber defined within the guiding portion. When the cover is driven to slide, the coined convex collar sections smoothly guide the pins of the IC package to enter into the gap between the contact tabs and decrease frictional resistance exerted on the pins by the contacts.
