A probe connector includes an insulating housing defining inserting passages each longitudinally penetrating therethrough with a blocking rib being protruded in a periphery inside thereof. A probe has a base board of which a front end has a contact head stretched forward out of the inserting passage, and a rear end has a resisting board extending downward from an end edge thereof and two blocking boards protruded downward from two side edges thereof for cooperating with the blocking rib to prevent the probe from sliding out of the inserting passage. A terminal has a base plate blocking a rear end of the inserting passage, and an elastic arm extending forward from a top of the base plate with a free end designed as a contact portion abutting against the base board. An elastic element is retractably located between the resisting board and the base plate.
