Which device is used to physically and electrically connect two or more conductors?

The device that is used to physically and electrically connect two or more conductors is known as a connector. Connectors are specifically designed to establish a secure and conductive pathway for electrical signals or power, ensuring that the connection can handle the appropriate electrical load while maintaining safety and reliability.

Connectors come in various types and specifications tailored for different applications, including wire-to-wire connections, wire-to-board connections, and more. Their design typically includes metal contacts that make the electrical connection and a housing that provides mechanical stability. This allows them to be used in a variety of environments, ensuring durability and efficiency in electrical systems.

In contrast, a junction box serves as a protective enclosure for electrical connections but does not inherently connect conductors; it merely houses the connections. A coupler generally refers to a device that connects two cables or flexible conduits but is not commonly used for conductors in traditional electrical contexts. An adapter, on the other hand, is often used to facilitate compatibility between different types of connectors or sockets rather than serving the primary function of connecting conductors directly.

Understanding the role and functionality of connectors is vital for anyone working with electrical systems, as proper connections are essential for system integrity and safety.
