Electrical connector

An electrical connector for interconnecting a daughter card to a printed circuit board, comprising:

• a dielectric housing including a first part, a second part, a card receiving slot defined between the first and second parts, and a plurality of contact receiving cavities defined in the first and second parts, the first and second parts each having an inner wall facing toward each other, said first inner wall and said second inner wall directly facing to and communicating with said card receiving slot and commonly defining exactly only said card receiving slot therebetween;
• a plurality of contacts received in the contact receiving cavities of the housing, each contact having an engaging portion and a mounting portion;
• a card ejector mechanism pivotally attached to the housing;
• and
• said inner walls of the first and second parts each forming a plurality of separate projections thereon extending into the card receiving slot of the housing for limiting transverse movement of the daughter card inserted in the card receiving slot, each projection being positioned between two adjacent contact receiving cavities of the housing, each projection on the inner wall of the first part being aligned with a corresponding projection on the inner wall of the second part, and a distance from each projection on the inner wall of the first part to the corresponding aligned projection on the inner wall of the second part being substantially equal to a thickness of an edge of the daughter card, a total number of said projections being less than that of the contacts;
• wherein the engaging portion of each contact and each projection respectively abut against a corresponding gold finger and a dielectric area between adjacent gold fingers of the daughter card;
• wherein each projection forms a chamfer at an upper end thereof for facilitating insertion of the daughter card into the card receiving slot.
