Description

Plug assembly and connector assembly including the same The following disclosure relates to a plug assembly and a connector assembly including the same. A connector is a type of electrical component capable of connecting or disconnecting electrical connections. Connectors are used in various electromechanical devices, such as automobiles or household appliances, to provide electrical and/or physical connections between multiple electronic components.
