Socket connectors are essential components used to establish electrical connections between devices. They allow for the easy attachment and detachment of cables, enabling the transfer of power or data. Commonly found in various applications, such as computers and audio equipment, socket connectors come in different shapes and sizes to accommodate specific needs. These connectors typically consist of a male and female part, where the male part plugs into the female socket. This design ensures a secure connection while allowing for flexibility in setup. Examples of socket connectors include USB for data transfer and AC power sockets for electrical devices.
