Connector assembly

A connector assembly comprising a plug connector and a receptacle connector which are mateable with each other, wherein:

• the receptacle connector includes a receptacle insulator and a row of receptacle terminals held by the receptacle insulator;
• the receptacle terminals are staggered in arrangement;
• each of the receptacle terminals has a main contact point, a support contact point, and a resilient portion, wherein the resilient portion connects between the support contact point and the main contact point;
• for each of the receptacle terminals, the main contact point and the support contact point are apart from each other in a width direction;
• the plug connector includes a plug insulator and a row of plug terminals held by the plug insulator;
• the plug terminals are staggered in arrangement;
• each of the plug terminals has a main contact portion, a support contact portion, an insertion end portion, a contact difference and an additional contact difference;
• for each of the plug terminals, the main contact portion and the support contact portion are apart from each other in the width direction;
• for each of the plug terminals, a part of the insertion end portion is larger than a minimum distance between the main contact portion and the support contact portion in the width direction;
• the contact difference is positioned at a boundary between the insertion end portion and the support contact portion;
• the additional contact difference is positioned at a boundary between the insertion end portion and the main contact portion;
• the receptacle terminals correspond to the plug terminals, respectively;
• the insertion end portion of each of the plug terminals is inserted between the main contact point and the support contact point of the receptacle terminal corresponding thereto, when the plug connector is mated with the receptacle connector;
• under a mated state where the plug connector and the receptacle connector are mated with each other, the main contact points are in contact with the main contact portions while the support contact points are in contact with the support contact portions;
• and
• the main contact portion of each of the plug terminals is flush with the support contact portion of the plug terminal adjacent thereto.
