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.
The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or devices. An adapter can be used to effectively bring together dissimilar connectors. There are hundreds of types of electrical connectors. Connectors may join two lengths of flexible copper wire or cable, or connect a wire or cable to an electrical terminal. In computing, an electrical connector can also be known as a physical interface (compare physical layer in OSI model of networking). Cable glands, known as cable connectors in the US, connect wires to devices mechanically rather than electrically and are distinct from quick-disconnects performing the latter.
