  • Patent number: 7517224
    Abstract: An IC socket includes a socket body (1) having a plurality of passageways (10) extending obliquely from a mating surface (101) toward a mounting surface (103). At least two terminals (2) are insertable into each of the passageways. Thus, even if the at least two terminals are laterally and obliquely movable with respect to an end of the passageway upon the pressure of the IC package toward the IC socket, effective electrical connection between the IC package and the printed circuit board are also established through the use of the IC socket due to having every two terminals of one passageway employed for electrically mating with a common contact pad of the IC package or a common conductive element (31) of the printed circuit board.

  • Patent number: 7445464
    Abstract: An IC socket includes a plurality of terminals (7) arranged in a matrix defined by row and column directions perpendicular to each other. The terminal includes a contact arm (73) extending from a middle portion of the terminal. The contact arm includes a first resilient arm (731) extending essentially towards the row direction in a first direction, from a top view, and a second resilient arm (733) angled with the first resilient arm and extending essentially towards the row direction in a second direction, from the top view, different from the first direction. Since the second resilient arm extends essentially toward the row direction, rather than parallel to the row direction, and a larger recess is formed between respective resilient arms of adjacent terminals in a same row, there will not be apt to form a short circuit between any portions of the first lower resilient arm and the second upper resilient arm.
