A high frequency signal communication connector with improved crosstalk performance includes an insulated housing, a plurality of first terminals, a plurality of second terminals, a conductive shielding layer, and a metal shell. The insulated housing has two inserting slots. The first and second terminals are disposed in the insulated housing, and have front ends respectively extending into the two inserting slots, and rear ends respectively extending outside a bottom of the insulated housing. The conductive shielding layer is provided on the insulated housing, and is disposed with a plurality of through holes. The first and second terminals respectively pass through the through holes, so that the conductive shielding layer covers a part of the first and second terminals. The first and second terminals have grounding terminals contacting with the conductive shielding layer, so that the terminals have better shielding effectiveness to reduce crosstalk interference.
