Plug-and-Socket Connection
Plug-and-Socket Connection
a detachable device for the quick connection and disconnection of electric circuits. Electric contacts in the form of metal jacks and of metal pins or blades that are inserted into the jacks constitute the basis of a plug-and-socket connection. The number of contacts may range from one to several hundred; in the latter case, the device is often called a plug-and-socket connector. The simplest type of plug-and-socket connection is the plug and socket used to connect portable household or industrial appliances to an outside power supply.
