Printed circuit board plug connector with two shielded contact banks disposed on mutually perpendicular printed circuit boards

Claim 1

A printed circuit board plug connector, comprising: a) a first printed circuit board, and a second printed circuit board perpendicular to said first printed circuit board and having opposite sides with upper and lower surfaces and an edge region with a longitudinal edge; b) a first contact bank disposed on said first printed circuit board and having sides, and a second contact bank disposed in said edge region and protruding at said longitudinal edge of said second printed circuit board, said second contact bank having a plug-in area and having a body with a lower surface and electrical connections protruding from said lower surface of said second printed circuit board; c) a metal shielding element attached to said first printed circuit board, said metal shielding element being a rigid, rectangular, circumferentially closed frame shieldingly surrounding said sides of said first contact bank, said frame having longitudinal walls and transverse walls with inner surfaces, and metal sheets being feathered at narrow intervals and attached circumferentially to all of said inner surfaces of said walls of said frame in the form of inwardly curved, resilient, inner contact elements; d) insert pins plugging said metal shielding element into bores formed in said first printed circuit board for attaching said metal shielding element to said first printed circuit board; e) two metal shielding shells attached to said second printed circuit board and enclosing said second contact bank, insert pins plugging said shielding shells into bores formed in said second printed circuit board for attaching said shielding shells to said opposite sides of said second printed circuit board; f) one of said shielding shells completely enclosing said second contact bank on said upper surface of said second printed circuit board except for said plug-in area; and g) the other of said shielding shells being attached to said lower surface of said second printed circuit board and completely covering said lower surface of said second contact bank body including said electrical connections, except for said plug-in area; h) said metal shielding element together with said two metal shielding shells completely surrounding and shielding the plug connector when said first and second contact banks are plugged together.
