ABSTRACT:
An electrical connector comprises a dielectric base defining a number of contact receiving holes, a slidable cover fixed to the base and defining a number of pin receiving slots 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 main body for supporting the contact, a contact portion comprising contact tabs extending from the main body for electrically contacting the corresponding pin of the IC package, a guiding portion extending from the contact tabs for guiding the corresponding pin of the IC package to properly engage with the contact tabs, and a soldering portion extending from the main body for being surface mounted to a circuit board. The soldering portion of each contact comprises a pad adapted for being surface mounted to the circuit board, and a shoulder extending from and projecting above the plane of the pad for preventing molten solder from wicking upwards. A neck is formed between the main body and the soldering portion for providing the soldering portion with proper resiliency relative to the main body. A pair of cutouts is defined in the main body of the contact at opposite sides of the neck and proximate the shoulder for receiving molten solder therein and for preventing the molten solder from further wicking upwards.
