Claim:
An electrical connector comprising: a housing defining a plurality of passageways, each of said passageways defining an upper section and a lower section of a diameter larger than that of the upper section; a plurality of contact sets respectively disposed in said passageways, each of said contact sets including an upper contact, which is located in the upper section and defines a lower end extending into the lower section and below an interface between said two sections, engageably supported by a lower contact, which is retained in the lower section of the passageway, an upper end of the upper contact extending above an upper surface of the housing for engaging with an electrical package; wherein the upper contact is configured to be capable of moving up and down between the upper section and the lower section, relating to the lower contact in a restraint manner under condition that at least one of said upper contact and said lower contact is compliant to provide a restored force to ensure electrical connection between said upper contact and said lower contact when the upper contact is moved toward said lower contact; wherein a free end of the lower end of the upper contact forms a flange abutting against the interface to limit upward movement of the upper contact; and wherein the free end extends along a direction angled with a movement direction of the upper contact, which is outwardly away from a centerline of the passageways.
