Anti-misinsertion structure of socket connector

A socket connector, comprising:

• an insulating base, having a docking space for inserting a plug connector, a plurality of conductive terminals installed in the docking space, and a clasp slot formed on both sides of a top of the insulating base and interconnected to the docking space;
• an anti-misinsertion component, having a pivot and two connecting arms extended respectively and horizontally from both sides of the pivot, wherein the connecting arms have a guide piece extended horizontally from an end of the connecting arms, the connecting arm, and a stop piece formed at a bottom of each of the connecting arms and proximate to the guide piece of the connecting arm;
• and
• a shielding casing, covered onto an external periphery of the insulating base, and having a plug hole formed at a position opposite to the docking space of the insulating base, and an elastic plate installed separately on both sides of the top of the shielding casing;
• wherein, the anti-misinsertion component is installed in the clasp slot of the insulating base, and the elastic plate of the shielding casing abuts a recessed portion of the anti-misinsertion component, so that the anti-misinsertion component is capable of preventing a plug connector of a different specification from being inserted into the docking space.
