Electrical connecting assembly

An electrical connecting assembly, comprising:

• an electrical connector comprising a plurality pairs of signal terminals and a plurality of ground terminals, one ground terminal being disposed between two pairs of adjacent signal terminals, each of the signal terminals comprising a bent part and a signal terminal plugging part, the bent part being adjacent to the signal terminal plugging part, each of the ground terminals comprising a shielding part and a ground terminal plugging part, the shielding part being adjacent to the ground terminal plugging part;
• the shielding part corresponding to the bent part;
• and
• a circuit board comprising a plurality pairs of signal terminal plugging holes and a plurality of signal ground terminal plugging holes, the plurality of ground terminal plugging holes being arranged along a baseline;
• one ground terminal plugging hole being disposed between the two pairs of signal terminal plugging holes, each pair of the signal terminal plugging holes being respectively disposed on two sides of the baseline, the bent parts of the plurality of the signal terminals alternately extending to two sides of the baseline, the signal terminal plugging parts being respectively inserted into the signal terminal plugging holes and being electrically connected to the circuit board, the ground terminal plugging part of each of the ground terminals being correspondingly inserted into the ground terminal plugging hole and being electrically connected to the circuit board;
• wherein the width of the shielding part in a direction orthogonal to the baseline is greater than or equal to the length of the bent part of each of the signal terminals extending toward two sides of the baseline.
