Patent ID: 7074085

Claim:
An electrical connector assembly for connecting a first and a second circuit boards, comprising: a plug connector mounted on the first circuit board, comprising: a first insulative housing having a mounting face, a mating face, side walls and a number of contact receiving slots therethrough in the side walls; a plurality of first contacts received in the contact receiving slots, each first contact having a soldering portion extending along said mounting face for surface mounting on said first circuit board in a first direction; a pair of first shielding plates attached to the housing, each shielding plate having a main portion located outside the soldering portion and extending in a second direction perpendicular to said first direction, and a grounding pad extending along said mounting face for surface mounting on said first circuit board; a receptacle connector mounted on the second circuit board, comprising: a second insulative housing defining a mounting face, a mating face, side walls and a number of contact receiving slots therethrough in the side walls; a plurality of second contacts received in the contact receiving slots, each second contact having a soldering portion extending along said mounting face for surface mounting on said second circuit board in said first direction; a pair of second shielding plates attached to said second housing and contacting with the first shielding plates, and having a main portion disposed outside the soldering portion of the second contact and extending in said second direction, and a grounding pad extending along said mounting face for surface mounting on said second circuit board wherein said first shielding plate has an inclined tab extending inwardly from an upper edge thereof, said second shielding plate has a lead-in tab extending outwardly form an upper edge thereof and cooperating with the inclined tab for easing the insertion of the plug connector into the receptacle connector; wherein the first housing and second housing having a number of grooves respectively, the shielding plate both in the plug and the receptacle connector defining a pair of locking tab opposing each other and provided with barbs on opposite edges thereof for interference engagement with the grooves respectively.
