AI summary

An electrical connector includes an insulative housing and a plurality of contacts disposed in the housing. The contacts are arranged with upper contacts in the upper row and lower contacts in the lower row. The upper contacts include the grounding contacts and the signal contacts as well as the lower contacts. A metallic shielding plate is located between the upper contacts and the lower contacts. The metallic shielding plate forms a plurality of holes. In each hole, there are upper spring beam and lower spring beam respectively contacting the front contacting sections of the grounding contacts in the upper row and in the lower row.
