Double-layer circuit board connector structure and assembly method thereof

A connector structure, comprising:

• a housing, comprising an accommodating space and an insertion opening defined on the front side thereof communicating with accommodating space;
• a first circuit module, arranged inside the accommodating space, comprising a first circuit board, a first molding block and a plurality of first connecting members, a front end of the first circuit board facing the insertion opening, and each of the first connecting members electrically connected to a rear end of the first circuit board, and the first molding block attached to the rear end of the first circuit board to make the first connecting members pass through the first molding block to protrude outward from a rear end of the first molding block;
• a second circuit module, arranged inside the accommodating space and stacked on the first circuit module, comprising a second circuit board, a second molding block and a plurality of second connecting members, a front end of the second circuit board facing the insertion opening, and each of the second connecting members electrically connected to a rear end of the second circuit board, and the second molding block attached to the rear end of the second circuit board to make the second connecting members pass through the second molding block to protrude outward from a rear end of the second molding block;
• and
• a shielding member, arranged between the first circuit board and the second circuit board, comprising a first shielding surface facing an electrical connection area between the first connecting members and the first circuit board, and a second shielding surface facing an electrical connection area between the second connecting members and the second circuit board.
