Editing Edge connector (section)

== Socket design ==
Edge connector sockets consist of a plastic "box" open on one side, with pins on one or both sides of the longer edges, sprung to push into the middle of the open center. Connectors are often [[Key (engineering)|keyed]] to ensure the correct [[Electrical polarity|polarity]], and may contain bumps or notches both for polarity and to ensure that the wrong type of device is not inserted. The socket's width is chosen to fit to the thickness of the connecting PCB.

The opposite side of the socket is often an [[insulation-piercing connector]] which is clamped onto a [[ribbon cable]]. Alternatively, the other side may be [[Soldering|soldered]] to a [[motherboard]] or [[daughtercard]].
