Barrel Connector AdaptersConnectors and interconnects are devices that are used to connect two or more electronic components together. They come in a wide variety of shapes and sizes, and are used in a wide variety of electronic devices, from smartphones and computers to televisions and appliances. Barrel connectors are a type of connector that are commonly used in low-voltage applications, such as in consumer electronics and hobby projects. They are cylindrical in shape and have two or more metal contacts that are used to transfer electrical signals between components. Barrel connector adapters are devices that are used to connect two or more barrel connectors together, or to connect a barrel connector to a non-barrel connector. They are commonly used to convert the type of connector, or to extend the length of a cable. For example, a barrel connector adapter could be used to convert a 3.5 mm audio jack to a 2.5 mm audio jack, or to extend the length of a DC power cable.
