An obversely and reversely pluggable connector structure, includes a multi-plate circuit board, first transmission conductor set and second transmission conductor set each, a plurality of first soldering faces and second soldering faces, a plurality of first conduction portions and second conduction portions, a plurality of first through holes and second through hole portions, a first shielding shell and second shielding shell each, first capacitor unit and second capacitor unit each at least, allowing the first transmission conductor set and second transmission conductor set different in length to clamp a connector to the circuit board together through the above components, and components for soldering, conducting, reducing noise are configured correspondingly to each transmission conductor set, thereby achieving the reduction of the volume upon a connector assembly, and having the effect of decreasing EMI (Electromagnetic interference) and RFI (radio frequency interference).
