Techopedia explains Lightning Connector. The Lightning connector was a successor to the previously used 30-pin connector. It is a small wire with a USB 2.0 interface at one end and a connector plug at the other. The connector consists of a communication bus for dual data transfer; it also provides electrical power to the device.
Lightning rods or 'air terminals' are only a small part of a complete lightning protection system. In fact, the rods may play the least important role in a system installation. A lightning protection system is composed of three main components: 1  Rods or 'Air Terminals' - The small, vertical protrusions designed to act as the 'terminal' for a lightning discharge. 2  Conductor Cables - Heavy cables (right) that carry lightning current from the rods to the ground. Cables are run along the tops and around the edges of roofs, then down one or more corners of a building to the ground rod(s). Ground Rods - Long, thick, heavy rods buried deep into the earth around a protected structure.
