Electrical connector assembly with enhanced blind mating features

A connector, comprising:

• an insulative housing having a pair of elongated side walls and a pair of end walls connecting with said side walls thereby defining a mating cavity therebetween, a mating tongue extending upwardly in said mating cavity with a plurality of second contact grooves defined thereon, a plurality of first contact grooves defined on the side walls and correspondingly facing the opposite second contact grooves;
• a plurality of contacts divided into several contact groups which comprising at least a pair of contacts, each contact having a first contact portion received in the first contact groove and a second contact portion received in the second contact groove;
• at least one metallic shell surrounding a periphery of the insulative housing, the metallic shell comprising a body portion having a plurality of solder legs extending out of the insulative housing and a plurality of grounding arms projecting into the mating cavity and received in the first contact grooves between the first contact portions of neighboring contact groups;
• wherein a pair of guiding portions are formed at opposite ends of the insulative housing with guiding apertures defined thereon.

An electrical connector assembly comprising:

• a main printed circuit board;
• a first connector mounted to the main printed circuit board;
• a secondary printed circuit board position with regard to the main printed circuit board in a parallel relation;
• a second connector mounted to the secondary printed circuit board and facing toward the main printed circuit board;
• and
• a shell associated with the secondary printed circuit board and forming a guiding mechanism for blind mating with the first connector;
• wherein said shell is primarily located upon a surface of the secondary printed circuit board opposite to a surface on which the second connector is located.
