Patent attributes
An electrical connector assembly includes a socket connector soldered on one circuit board and a plug connector soldered on another circuit board. The socket connector includes an insulating socket base and a plurality of first terminals received in the first terminal-receiving slots of the insulating socket base. Each first terminal successively extends to form a first terminal lead, a first inverted U-shaped portion, a base U-shaped portion and an auxiliary-clamping portion. One leg of the base U-shaped portion includes a first elastic-contact portion. The plug connector includes an insulating plug base and a plurality of second terminals received in the second terminal-receiving slots of the insulating plug base. Each second terminal successively extends to form a second terminal lead and a second inverted U-shaped portion having a second elastic-contact portion. The second inverted U-shaped portion of the second terminal is inserted into the base U-shaped portion of the first terminal, and the first elastic-contact portion contacts the second elastic-contact portion when mating. The invention can provide stable mating and electrical connection and is in compliance with recent downsizing trends.
