  • Publication number: 20140295705
    Abstract: A crosstalk-proof receptacle connector has multiple insulative boards, multiple sets of terminals, multiple sets of shielding plates and an outer casing. The insulative boards are arranged abreast. The sets of the terminals are mounted respectively in the insulative boards. The terminals of each set are classified into signal terminals and grounding terminals. Each set of the shielding plates is mounted on one of two opposite sides of a corresponding insulative board. The shielding plates of each set are spaced apart without contacting one another. Each shielding plate has multiple folding sections capable of interrupting signal noise. The outer casing covers the insulative boards to combine the insulative boards.
