ABSTRACT:
A card edge connector comprises an insulative housing, a number of first contacts and a corresponding number of second contacts. The housing defines a card receiving slot and a number of contact receiving cavities. The first and second contacts have spring portions including individual contacting portions that are located at different levels from a top face of the housing and are spaced a height which is greater than a vertical length of a tapered front edge of a daughter card mated with the connector. The spring portion of the second contact forms an S-shaped portion having a lower turning point spaced from a retention portion of the second contact a distance less than the vertical length of a free end of the second contact above a bottom face of the prestress portion that the free end of the second contact bears against. The S-shaped portion adjusts the length of the spring portion of the second contact when the daughter card is inserted into the housing and therefore prevents the second contact from buckling during insertion of the daughter card into the card receiving slot.
