Electrical connector with improved signal transmission performance

An electrical connector defining an insertion space configured to receive a tongue plate, the electrical connector further comprising:

• an installation body, the installation body comprising a first side wall, a second side wall opposite to the first side wall, and an installation space located between the first side wall and the second side wall;
• the insertion space extending along a first direction;
• a plurality of first conductive terminals, the plurality of first conductive terminals being directly or indirectly fixed to the installation body;
• each first conductive terminal comprising a first elastic arm located on an inner side the first side wall and a first contact tail extending from the first elastic arm;
• the first contact tail being located at a free end of the first conductive terminal;
• the first contact tail comprising a first contact area configured to contact a first conductive pad of the tongue plate;
• a portion of the first contact tail extending from the first contact area along a centerline direction of the first conductive terminal being a first extending stub;
• and
• a slider, the slider being movable in the installation space along an insertion and extraction direction which is parallel to the first direction;
• the slider comprising an abutment portion located on one side of the plurality of first conductive terminals along a second direction which is perpendicular to the first direction;
• the abutment portion being configured to be pushed by the tongue plate to move the slider from a first position to a second position;
• when the slider is located at the first position, the first contact tail of the first conductive terminal does not protrude into the insertion space;
• when the slider is located at the second position, the first contact tail of the first conductive terminal protrudes into the insertion space, the first contact area of the first contact tail is brought into contact with the first conductive pad of the tongue plate;
• wherein a length of the first extending stub extending along the centerline direction of the first conductive terminal is L1, and the first conductive terminal is configured to transmit a signal with a frequency corresponding to a first wavelength f1, where 0≤L1≤¼*f1.
