MX 3 Pin Powercon Female Socket Connector MX3MPA 20 Amp 250V (MX-2834)

Powercon connectors exist because a standard mains plug can work its way loose from vibration, cable movement, or just being bumped - something a touring lighting rig or a PA system running all night genuinely can't risk. This female socket locks positively to its matching male plug with a twist-and-click action, so the connection stays made until someone deliberately releases it. Rated to 20 amps, it handles the real current draw of professional audio and lighting gear rather than the lighter loads a standard IEC connector is built for. Building this socket into an enclosure or distribution panel gives it the same reliable locking connection the touring and installation industry relies on.
