An electrical connecting device is disclosed and includes a printed circuit board, an electrical connector, and a fixing gum. The electrical connector is used for electrically connecting a chip module onto the printed circuit board and has at least one gum positioning portion formed on at least one sidewall thereof. The gum positioning portion is non-coplanar with respect to the sidewall. The fixing gum adheres between and to the recess and the printed circuit board and is also attached in the recess. Because the gum positioning portion of the electrical connector is non-coplanar with respect to the sidewall, after the fixing gum is sprayed on the gum positioning portion, the electrical connector is reliably mounted on the printed circuit board to be prevented from falling off under an external force during a reflowing or due to shaking.
