For a drawer, equipped with electronics cards and inserted into a drawer-receiving structure through an opening provided in the front face of the drawer-receiving structure, a device for electromagnetically protecting the cards is formed by the front face of the drawer, and by the side faces, the top face, the bottom face, and the back face of the drawer-receiving structure, the faces being electrically conductive.

Device for protecting a drawer electromagnetically

A device for protecting an electrical connector for a printed circuit board from electromagnetic interference, the connector including a body having a front face to co-operate with a plug and a connection side face touching the board, and contacts, ending in spikes, the spikes being inserted through holes in the board to electrically connect the contacts to conductor tracks; the device including a first shielding element extending along a side face opposite from the connection side face, and continuing along a rear face so as to contact a grounding conductor track; and a second shielding element mounted on a face of the board opposite from the face of the board contacting the connector, and extending along the connection side face, the second shielding element contacting a conductor track, connected to the grounding track, so as to be electrically connected to the first shielding element thus forming a potential cage.

In this front face of an electronics card designed to be inserted into a housing through an opening, at least one of the edges of which opening is provided with a notched bar, that portion of said front face which is to be disposed in the vicinity of said bar is provided with at least one abutment surface for abutting against a drive member engaged through the notch when inserting said card into the housing or when extracting it therefrom. The method consists in inserting a drive member through one of the notches in said bar, in causing said member to bear against an abutment surface, and in exerting a pivot force on said drive member to pivot it about the zone via which it bears against an edge of the notch, so that a force is transmitted to the front face, at the abutment surface, in a direction corresponding to inserting the card or to extracting the card.

In a subrack, electronic circuit boards are connected to mother boards disposed in at least two planes parallel to the front face of the subrack. Each plane contains one or more mother boards. The planes are superposed to form a stack of compartments the general exterior envelope of which is generally pyramid shaped.

Subrack for electronic circuit boards and its support

In a subrack for electronic circuit boards connected to mother boards the mother boards are disposed in at least two planes parallel to the front face of the subrack. Each plane contains one or more mother boards. The planes are superposed to form a stack in the shape of a pyramid.
