Electrical connector and electrical connector assembly

A mating connector, comprising:

• a plastic body, having a main body and an insertion portion formed by extending forward from the main body, wherein a mating space is concavely formed backward from a front end surface of the insertion portion, the insertion portion has a side wall located at a periphery of the mating space and running through the mating space to form at least two through-holes, and the at least two through-holes do not communicate with each other;
• a metal cover, surrounding the plastic body and fastened to the main body;
• and
• a grounding sheet, located between the metal cover and the side wall, wherein the grounding sheet has a body and at least two elastic portions formed by bending and extending forward from the body, the body covers the side wall, and each of the at least two elastic portions is accommodated in a corresponding one of the at least two through-holes and enters the mating space,
• wherein at least one horizontal portion is formed by horizontally extending forward from the body, each of the at least one horizontal portion is located between two of the elastic portions, a barrier is provided between two adjacent ones of the through-holes, and the barrier blocks the horizontal portion from moving toward the mating space.
