  • 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.
