Cables and connectors

Abstract

A cable is provided comprising: a conductor configured to transmit electrical signals; and a shielding layer extending around the conductor, the shielding layer comprising a base layer and a solder layer stacked on top of each other, the solder layer being configured to be soldered to a grounding element of the shielding component to electrically connect the grounding element and the base layer. This facilitates soldering of the shielding layer to the grounding element, thereby improving product quality and production efficiency.
