An RJ45 socket connector includes an insulative housing and a terminal module received in the insulative housing. The insulative housing includes a receiving space, a number of partitions, and a number of receiving passageways each formed between every two adjacent partitions. The terminal module comprises an insulative body and a row of conductive terminals insert molded in the insulative body, the conductive terminal having a fixed portion fixed in the insulative housing and an elastic contact portion extending from the fixed portion and received in a corresponding receiving passageway. The insulative body defines a trough and a number of tubers disposed in the trough, every two adjacent tubers defining a groove for accommodating a downwardly moved conductive terminal.
