Electrical connector assembly

A combination of a media storage device, an electrical connector assembly and a printed circuit board of an electronic device, comprising:

• the media storage device having a frame, said frame retaining two rows of conductive pins therein;
• the electrical connector assembly comprising:
• a first connector having an insulative first housing receiving a plurality of first contacts therein, each contact having a first end formed as a receptacle for electrically engaging with a corresponding pin of the media storage device, and a second end formed as a pin and extending beyond the first housing;
• a guiding spacer having a top wall defining a number of holes therethrough, four side walls extending downwardly from the top wall and defining a chamber therebetween, said second ends of the first contacts extending through the holes of the top wall into the chamber;
• a second connector having an insulative second housing fittingly inserted into the chamber and retaining a plurality of second contacts therein, each second contact having a contacting portion electrically engaging with the second end of a corresponding first contact and a tail portion for soldering to the printed circuit board;
• and
• the printed circuit board of the electronic device;
• wherein
• at least one post is provided on a top wall of the insulative first housing engagable with a guiding groove in the frame of the media storage device for positioning the first connector relative to the media storage device;
• wherein
• a supporting wall projects upwardly from a side of the top wall of the guiding spacer which supports a rear end of a top wall of the first housing.
