Electrical connector

An electrical connector, comprising:

• an insulative body;
• and
• an upper terminal module and a lower terminal module which are assembled with each other and together are provided to the insulative body;
• the upper terminal module comprising a plurality of upper terminals and an upper insulative frame;
• the plurality of upper terminals comprising multiple upper signal terminals and at least one upper ground terminal, the multiple upper signal terminals forming upper signal terminal pairs which are spaced apart from each other by the at least one upper ground terminal;
• each upper terminal having an upper vertical segment, an upper horizontal segment, and an upper bending segment which is connected between the upper vertical segment and the upper horizontal segment;
• the upper vertical segment having a first upper held portion, an upper extension portion which extends from the first upper held portion, and an upper soldering portion which extends from the upper extension portion;
• the upper horizontal segment having a second upper held portion and an upper cantilevered arm portion which extends from the second upper held portion;
• the upper insulative frame having a first embedding portion which embeds the first upper held portions of the upper vertical segments of the plurality of upper terminals and a second embedding portion which embeds the second upper held portions of the upper horizontal segments of the plurality of upper terminals;
• and
• the first embedding portion having at least one first recessed groove which corresponds to the at least one upper ground terminal in position.
