Shielded board-to-board connector

A board-to-board connector, comprising:

• a receptacle comprising a plurality of first signal contact elements, wherein each of the plurality of first signal contact elements is configured to be electrically connected to a first printed board of a plurality of printed boards;
• and
• a plug comprising a plurality of second signal contact elements, wherein each of the plurality of second signal contact elements is configured to be electrically connected to a second printed board of the plurality of printed boards, and each of the plurality of second signal contact elements is configured in a manner that, when the plug is inserted into the receptacle, each of the plurality of second signal contact elements of the plug is in contact with a corresponding first signal contact element of the plurality of first signal contact elements of the receptacle;
• wherein the receptacle further comprises a first electromagnetic interference shield which continuously or discontinuously surrounds the plurality of first signal contact elements of the receptacle, and the plug further comprises a second electromagnetic interference shield which continuously or discontinuously surrounds the plurality of second signal contact elements of the plug;
• wherein the first electromagnetic interference shield of the receptacle and the second electromagnetic interference shield of the plug are configured in a manner that, when the plug is inserted into the receptacle, the first electromagnetic interference shield of the receptacle and the second electromagnetic interference shield of the plug are in direct contact with each other, and an area of direct contact between the first electromagnetic interference shield of the receptacle and the second electromagnetic interference shield of the plug extends along an entire perimeter of the board-to-board connector;
• wherein the second electromagnetic interference shield of the plug is provided with a first plurality of abutment portions configured to bring the second electromagnetic interference shield of the plug into direct contact with the first electromagnetic interference shield of the receptacle, and abutment portions of the first plurality of abutment portions are positioned at intervals around the entire second electromagnetic interference shield of the plug;
• and
• wherein each of the first plurality of abutment portions comprises a respective leaf spring, each of the first plurality of abutment portions outwardly projects from a respective surface of the second electromagnetic interference shield of the plug in a respective oblique direction, and each of the first plurality of abutment portions is configured to be elastically deformed by abutment with the first electromagnetic interference shield of the receptacle when the plug has been inserted into the receptacle.
