1. An electrical connection device comprising:
a cable-end connector comprising:
a housing comprising a housing body and a mating plate, the housing body having a front end face, the mating plate protruding from the housing body and having a front end portion positioned in front of the front end face; and
a circuit board supported by the housing body, partially protruding relative to the front end face and spaced apart from the mating plate;
a board-end connector comprising:
a base formed with a mating slot which is used to allow the circuit board to mate therewith;
a plurality of terminals supported by the base and used to electrically connect the circuit board; and
a metal outer shell sheathing the base, a mating groove being formed between the metal outer shell and the base and being used to allow the mating plate to mate therewith, wherein
one of the base and the metal outer shell is provided with at least one protruding member protruding outwardly therefrom;
when the cable-end connector properly inserts into the board-end connector, the cable-end connector mates with the board-end connector, the protruding member abuts against the front end face of the housing body, and the mating plate mates into the mating groove between the metal outer shell and the base of the board-end connector; and
when the cable-end connector reversely inserts into the board-end connector, the protruding member stops the front end portion of the mating plate so as to prevent the cable-end connector from mating with the board-end connector.
