eSATA connector structure

An improved eSATA connector structure, comprising:

• a base having a containing space defined therein, a retaining wall formed at a front end of the containing space, and an opening formed on the retaining wall;
• a circuit board installed in the containing space, and an end of the circuit board passing through the opening and out of the retaining wall, at least one side of the circuit board having a plurality of conductive pins, a transmission line segment being extended from an end of the conductive pin, ends of the transmission line segments being respectively and electrically coupled to a plurality of conductive terminals;
• a slideway separately formed on both sidewalls of the containing space;
• and
• a casing mounted onto the exterior of the base, the casing having a hollow main body and a port formed at a front end of the main body for exposing the circuit board,
• wherein the base is made of an insulating material, and
• wherein the retaining wall includes a bottom tray extended from the bottom of the retaining wall, and a gap is defined between the retaining wall and the bottom tray.
