[ background of the invention ]

An electrical connector includes an insulative housing and two rows of conductive terminals disposed on the insulative housing, wherein the insulative housing has a slot, and the two rows of conductive terminals are exposed from the slot. When the electric connector is in butt joint with an electronic card, the electronic card is inserted into the slot to be contacted with the conductive terminals, so that signal transmission between the electric connector and the electronic card is realized.

However, since the thickness of the electronic card is smaller than the width of the insertion slot, two cases occur when the electronic card is inserted into the insertion slot. In the first case: when the electronic card is obliquely inserted into the slot, because the thickness of the electronic card is smaller than the width of the slot, and a gap is formed between the electronic card and the slot, the electronic card is excessively inclined when being inserted into the slot, so that the electronic card cannot be well butted with the conductive terminals, and the transmission of signals between the electric connector and the electronic card is influenced. In the second case: when the electronic card is vertically inserted into the slot to a final position, because the thickness of the electronic card is smaller than the width of the slot, a gap is formed between the electronic card and the inner wall surface of the insulating body, when the electric connector and the electronic card are subjected to external force, the electronic card is easy to shake left and right in the slot, the electronic card is excessively displaced, the electronic card cannot be well butted with the conductive terminal, and therefore signal transmission between the electric connector and the electronic card is influenced.

Therefore, there is a need to design an electrical connector to solve the above-mentioned technical problems.
