Rectangular ConnectorsConnectors, interconnects, and terminals are all types of electronic components that are used to connect circuits together. Rectangular connectors are a specific type of connector that are typically used to connect circuit boards or other electronic devices together. They are called rectangular connectors because they have a rectangular shape, with two rows of metal pins or sockets that provide the electrical connections. These connectors are often used in computers, audio and video equipment, and other electronic devices where a compact, high-density connection is required.
