Electrical connector and mounting method thereof with improved mounting features

An electrical connector, comprising:

• a sub-connector, the sub-connector comprising an insulating body and a plurality of conductive terminals, the insulating body defining a slot, each conductive terminal comprising a tail portion and a mating portion protruding into the slot, the slot being configured to receive an electronic card;
• and
• an identification connector, the identification connector comprising a plurality of identifying conductive terminals and a conductive element;
• each identifying conductive terminal comprising a connecting portion;
• the plurality of identifying conductive terminals being configured to be in contact with a circuit board;
• wherein the conductive element connects the connecting portions of at least two of the identifying conductive terminals among the plurality of identifying conductive terminals, so as to transmit an identification signal to the circuit board.

A method for mounting an electrical connector to a circuit board, the electrical connector comprising:

• an outer insulating body, the outer insulating body comprising an accommodating space and a second slot located beside the accommodating space along a first direction;
• a first sub-connector, the first sub-connector comprising a first insulating body and a plurality of first terminals fixed to the first insulating body;
• the first insulating body defining a first slot;
• each first terminal comprising a first mating portion extending into the first slot and a first tail portion configured to be mounted on the circuit board;
• the outer insulating body being sleeved on the first sub-connector;
• the first insulating body being accommodated in the accommodating space;
• the first slot and the second slot being arranged along the first direction;
• and
• a terminal module, the terminal module comprising a plurality second terminals and a plurality of cables connected to the plurality of second terminals, each second terminal comprising a second mating portion extending into the second slot and a second tail portion connected with a corresponding cable;
• the method comprising steps of:
• S1, mounting the first tail portions of the first terminals of the first sub-connector on the circuit board;
• S2, assembling the terminal module into the outer insulating body;
• and
• S3, mounting the outer insulating body together with the terminal module on the circuit board, wherein the first insulating body is accommodated in the accommodating space.
