The cable includes a pair of low-speed differential signal conductors electrically connected to a pair of low-speed differential signal pads a6, a7 and one ground conductor electrically connected to one ground pad G. Therefore, by adding one grounding bonding pad and one grounding conducting wire, the electromagnetic interference can be reduced, and the stability and the reliability of signals can be improved.

As shown in fig. 1 to 5, in the illustrated embodiment, the row of wire pads 220b on the front surface of the second end 222 of the circuit board 220 further includes two other ground pads G respectively located on the outermost sides of the row of wire pads 220 b.

As shown in fig. 1 to 5, in the illustrated embodiment, the row of wire pads 220b on the front surface of the second end 222 of the circuit board 220 includes a pad G, a pad a2, a pad A3, a pad a5, a pad G, a pad a6, a pad a7, a pad A8, a pad a10, a pad a11, and a pad G, which are arranged in order from side to side.
