Abstract: An electrical connector (10) for receiving a circuit board (9) includes an elongated housing (1), a slot (2) lengthwise extending therein for receiving the lower portion of the board (9). A plurality of contacts (3) are side by side positioned transversely to the slot (2) for engagement with the conductive pads (91) disposed on the lower portion of the board (9). A pair of posts (17) are respectively positioned at two ends of the slot (2), each having a peg (20) at the top to be received in a corresponding hole (92) for preventing the upward withdrawal of the board (9). A pair of pivotal latches (4) are positioned ate two ends of the housing (1), which lies forward obliquely at a predetermined angle in an initial rotatable positioned for the convenience of insertion of the board (9), and further rotates with the board (9) until is fixedly secured to the housing (1) in a final fixed position. The latch ( 4) further includes a holding device (48) to retain the board (9) therein during rotation of the board (9).
