Stacked electrical connector assembly

A stacked connector assembly comprising:

• an upper connector defining an insulative upper housing with a plurality of upper contacts therein and enclosed in an upper metallic shield;
• a lower connector located under the upper connector and defining an insulative lower housing with a plurality of lower contacts therein and enclosed in a lower metallic shield;
• said upper connector and said lower connector being discrete from each other under a condition that the insulative upper housing of the upper connector and the insulative lower housing of the lower connector are separate from each other;
• and at least one of said upper shield and said lower shield including unitarily a fastening device extending toward and actively fastened to the other of said upper shield and said lower shield to fasten said discrete upper and lower connectors together;
• wherein said fastening device is originally, in an extended manner in a horizontal direction for assembling the upper connector and the lower connector along said horizontal direction and successively deformed to a final bent shape in a vertical direction to fasten the upper connector and the lower connector together only after the upper connector and the lower connector reach corresponding final positions with each other.

A stacked connector assembly comprising:

• an upper connector defining an upper insulative housing with a plurality of upper contacts therein and enclosed in an upper metallic shield which defines a horizontal direction;
• a lower connector located under the upper connector and defining a lower insulative housing with a plurality of lower contacts therein and enclosed in a lower metallic shield which defines the same horizontal direction;
• said upper connector and said lower connector being discrete form each other under condition that the insulative upper housing of the upper connector and the insulative lower housing of the lower connector are separate from each other;
• and
• one of said upper housing and said upper shield defining a portion located inside a section of one of said lower housing and said lower shield in a vertical direction for assuring retention between the upper connector and the lower connector in said vertical direction when assembled under condition that the upper connector is horizontally assembled to the lower connector in said horizontal direction;
• wherein
• a fastening device extends in said vertical direction and horizontally engages said portion for assuring retention between the upper connector and the lower connector in the horizontal direction.
