Electrical connector with anti-mismatching mechanism

An electrical connector comprising:

• a base defining a plurality of receiving holes receiving a plurality of contacts therein;
• a cover slidably mounted on the base and defining a plurality of through holes corresponding to the receiving holes of the base;
• wherein
• the base and the cover comprise complementary interengaging anti-mismatching means adapted to avoid mismatching of the base and the cover.

A method of assembling a plurality of different models electrical sockets without risks of mis-assembling, comprising steps of:

• providing a plurality of different models electrical socket with different covers attached to the different bases in a vertical direction, respectively;
• providing anti-misassembling means on both the cover and the base for each socket, either positions or configurations of said anti-misassembling means of said different sockets being different from one another;
• wherein
• the different anti-misassembling means on different covers and bases are offset from each other during assembling while those of the same socket being compliantly aligned with each other, thus preventing mis-assembling between the cover and the base belonging to different models.
