Cable assembly, signal transmission structure, and electronic device

A device comprising:

• a signal transmission structure comprising:
• a circuit board comprising:
• a plurality of conductive holes;
• a first side comprising a first surface;
• and
• a second side comprising a second surface;
• a chip assembled on the first surface and electrically coupled to each of the conductive holes, wherein the second side is away from the chip;
• and
• a cable assembly that is assembled on the second surface, that is configured to implement signal transmission with the chip, and that comprises:
• a plurality of cables that is electrically coupled to the conductive holes;
• a base comprising a third surface comprising one or more conductive parts configured to be grounded;
• and
• a plurality of cable units installed on the base, wherein each of the cable units comprises a grounding part electrically coupled to the one or more conductive parts, and
• wherein the chip further comprises a ground pin electrically coupled to the one or more conductive parts using a corresponding one of the conductive holes.
