Duplex male electrical connector with a connection board movable inside a socket shell

A duplex male electrical connector, which can be bidirectionally inserted into a female socket for electrical connection, the duplex male electrical connector comprising:

• an insulating base having a front section formed with a connection board, the connection board having opposite top and bottom surfaces;
• two rows of first connection contacts disposed on the top and bottom surfaces of the connection board, respectively;
• a socket shell, which is formed with a connection slot having a front end serving as an insert port, the connection board being disposed in the connection slot, wherein the connection board in the socket shell and the connection board can vertically move relative to each other, such that the connection board can vertically move relative to the socket shell or the socket shell can vertically move relative to the connection board;
• and
• a returning structure, which is disposed between the socket shell and the insulating base, so that the connection board returns to a middle-range position of a height of the connection slot with the connection board being separated from the socket shell.

• and
• a position restricting structure, which restricts the connection board or an end section of the insulating base at a position within a middle section of a height of the socket shell.
