Abstract:
An electrical connector mounted on a printed circuit board and having a protection device for protecting the electrical connector from electromagnetic interference, said connector including a body made of a plastics material having a front face serving to co-operate with a removable plug and a connection side face touching the printed circuit board, said connector including a plurality of contacts, each of which has one end in the form of a spike that projects from the connection side face, said spikes being inserted through holes in said printed circuit board for a purpose of electrically connecting the contacts to one or more conductor tracks of said printed circuit, said protection device comprising a first shielding element extending along the side face of the connector that is opposite from the connection side face, and continuing along a rear face of the connector so as to come into contact with a grounding conductor track of the printed circuit board, and a second shielding element mounted on a face of the printed circuit board which is opposite from a face of the printed circuit board in contact with the connector, and extending along said connection side face, said second shielding element being in contact with a conductor track connected to said grounding track of the printed circuit board so as to be electrically connected to the first shielding element and so as to form a potential cage,wherein said second shielding element is constituted by a metal sheet which is in contact with a track disposed at a surface of the printed circuit board and connected to the grounding track to which the spikes of the first shielding element are connected; and wherein said printed circuit board is designed to equip a rack module provided with many electronics cards disposed side-by-side, and wherein the metal sheet is provided with resilient tongues projecting sideways from a fascia element so as to establish electrical contact with the shielding elements of a second connector carried by an adjoining electronics card that is held in said rack module.
