Shielding electrical connector and method of making the same

A method for making an electrical connector, comprising the steps of:

• forming a first insulating member by injection molding process, the first insulating member comprising a plurality of grounding contact receiving slots and a plurality of through holes;
• forming a shielding member onto the first insulating member by plating process, the shielding member defined on at least the inner surface of the grounding contact receiving slots and the inner surface of the through holes;
• forming a second insulating member on at least the shielding member of the through hole, the second insulating member comprising a plurality of columns formed into the through holes of the first insulating member, each of the columns comprising a signal contact receiving slot;
• assembling grounding contacts into the grounding contact receiving slots and signal contacts into the signal contact receiving slots, the grounding contacts connect the shielding member while the signal contact is isolated from the shielding member by the column.

An electrical connector comprising:

• a seat including a first insulating member and a second insulating member, said first insulating member defining a plurality of through holes extending therethrough in a vertical direction;
• a shielding layer coated upon an interior surface of each of the through holes;
• a second insulating member including a plurality of columnar bodies each with a corresponding signal contact disposed into the corresponding through hole and upon the corresponding coated interior surface of the corresponding through hole;
• wherein
• each of said columnar bodies defines a tubular structure in the corresponding through hole, and a thickness of said tubular structure is dimensioned much larger than a so-called layer by coating for efficiently holding the corresponding signal contact therein.
