Conductive devices designed and constructed to join electrical circuits together are known as electrical connectors. The connection may be permanent or temporary. Tools for assembly and removal may be required for the connection. The connection may even be for portable equipment, or may be a permanent electrical joint between two wires or devices. Electrical connectors are sometimes also referred to as physical interfaces.
There are several types of connectors in use. Simple electrical connectors that connect two or more wires to a single connection point are known as terminals.

Wire nuts are also some other types of single point connectors.
Terminal blocks also known as terminal boards or strips, crimp-on terminals or lugs, insulation displacement connectors, plug and socket connectors, and component and device connectors are some common types of connectors in use. Other commonly used connectors include 8P8C, DE-9 connectors, USD connectors, and R-TNC connectors for Wi-Fi antennas. Connectors known as automotive electrical connectors include car housing connectors, trailer connectors, and automotive relay connectors.
