Electrical connector and electrical connector combination fixable on a circuit board and to conducting wires

An electrical connector, comprising:

• a first insulating housing, having a front end provided with a first coupling cavity and a receiving cavity separately provided on a lateral side of and laterally aligned with the first coupling cavity;
• a second insulating housing comprising a second coupling cavity, the second insulating housing and the second coupling cavity being inserted into the receiving cavity of the first insulating housing from the front end of the first insulating housing and being fixed in the receiving cavity;
• a plurality of first conductive terminals, each first conductive terminal comprising a first contact portion extending forwards, a wiring portion extending backwards, and a first connecting portion located between the first contact portion and the wiring portion, the plurality of first conductive terminals being divided into upper and lower rows respectively provided on upper and lower sides of the first coupling cavity, and the plurality of first conductive terminals comprising a plurality of ground terminals and a plurality of signal terminals;
• a first shielding plate, located between the upper and lower rows of the first conductive terminals, the first shielding plate being wavy, and extending in an arrangement direction of the first conductive terminals, and the first shielding plate having a plurality of first crest portions and a plurality of first trough portions arranged alternately up and down, wherein one or more of the first connecting portions of the plurality of first conductive terminals contact the first shielding plate;
• and
• a plurality of conducting wires, respectively electrically connected to the wiring portions of the first conductive terminals.
