Abstract: An electrical connector (100) includes an insulative housing (10) having a slot (12), a row of low-speed signal contacts (18) and an insert module (16) received in respective opposite sides of the slot. The insert module has two rows of high-speed signal contact modules (40) confronting the row of low-speed signal contacts. The insert module is pivotable in the slot from a first position, where the connector is ready for receipt of a daughter board (70), to a second position, where the insert module and the row of low-speed contacts sandwich the daughter board therebetween. The electrical connector provides a pair of actuators (208) pivotably located at the top of the insulative housing. In the second position, the actuators abut against the back portion of the insert module to pivot toward the daughter board, thereby ensuring electrical connection between the high-speed contacts in the insert module and the solder pads on the daughter board.
