Compact interlocked electrical socket

A compact interlocked electrical socket comprising:

• a containment body provided with a plurality of receptacles adapted to receive respective pins of a plug;
• wherein each of said receptacles is electrically connected to a connector by means of a movable contact that moves between a closed contact position and an open contact position;
• and
• wherein said closed contact position allows an electrical connection between said receptacle and said connector, and said open contact position breaks the electrical connection between said receptacle and said connector;
• a plug lock member configured to mechanically lock said plug in said socket in said closed contact position,
• a breaker lock member configured to mechanically lock said movable contact in said open contact position, when said plug is not inserted in said socket;
• an actuation member that simultaneously actuates said plug lock member and said breaker lock member that operate said movable contact,
• a plurality of contact chains, one for each pole of said socket;
• wherein each contact chain comprises a receptacle provided with a downstream fixed contact, and a terminal that is provided with a respective upstream fixed contact;
• wherein said upstream and downstream fixed contacts are configured to be in mutual electrical contact by means of the movable contact;
• and
• wherein said upstream fixed contact is connected to an electric power source and said downstream fixed contact is connected to an electric load,
• wherein each of said movable contact is pressed by a contrast spring with a mobile mechanical device and can be alternately brought into contact with said fixed contacts or moved away from the fixed contacts;
• wherein each movable contact is configured to slide in a seat that only allows the moveable contact to move in a radial direction;
• wherein each movable contact is accommodated in a contact holder that slides in said seat and accommodates said contrast spring;
• wherein said contact holder is slidable on a respective cam of a plurality of cams formed on a cam disk;
• wherein said cam disk is rotatable through an angle that is defined by stroke limiters constituted by mechanical abutments;
• and
• wherein the rotation of said cam disk causes each contact holder and of the respective movable contact to slide in said radial direction.
