Abstract: An electrical connecting assembly includes a first connecting member, a second connecting member, and two pairs of differential conducting wires connected between the first connecting member and the second connecting member and provided to be adjacent to each other. Polarity arrangements of the first cable core and the second cable core of one pair of differential conducting wires at a first end thereof and at a second end thereof are opposite to each other, and polarity arrangements of the first cable core and the second cable core of the other pair of differential conducting wires at a first end thereof and at a second end thereof are identical to each other. The invention may reduce the remote crosstalk of the electrical connecting assembly, and performance of the remote crosstalk characteristics thereof in high frequency is good.

Abstract: An electrical connector is mounted on a circuit board and used to mate with a mating member. The electrical connector includes: a body made of a wave-absorbing material, the body having an upper surface, a lower surface and at least one first accommodating groove; and at least one ground terminal accommodated in the first accommodating groove. An upper end of the ground terminal is exposed to the upper surface and is in electrical contact with the mating member, and a lower end of the ground terminal is exposed to the lower surface and is electrically connected with the circuit board.

Abstract: An electrical connector includes an insulating block, and multiple differential signal terminals and multiple ground terminals embedded in the insulating block. Multiple first protruding blocks and multiple second protruding blocks protrude and extend forward from a front surface of the insulating block. A slot is formed between the first protruding block and the second protruding block adjacent to each other. Each differential signal terminal is embedded in and extends forward out of a first protruding block. Each of left and right sides of one pair of differential signal terminals has a first side surface. Each ground terminal is provided between two adjacent pairs of the differential signal terminals, and is embedded in and extends forward out of a second protruding block. Each of left and right sides of the ground terminal has a second side surface. A medium between the first side surface and the second side surface is air.
