Electric ground connection system between a coaxial plug and a plate of an ultra-high frequent circuit and electric connection device utilising a similar system.

摘要

The invention relates particularly to a system of electrical linking between an electronic circuit produced on a substrate (14) on an electrically conducting baseboard (13) fixed in an electromagnetic screening box and a coaxial socket (10) fixed against one outer wall (12) of the screening box, the core (16) of the socket (10) being engaged in a housing (18) of the wall (12) in order to be linked to the electronic circuit, the socket (10) having an earth surface situated facing the said wall (12), this system being characterised in that the earth contact between the socket (10) and the baseboard (13) is achieved by means of an electrically conducting ring (30) arranged coaxially with respect to the core (16), insulated from this core (16) and simultaneously in electrical contact with the earth surface of the socket (10) and the baseboard (13) when the socket (10) is fixed against the wall (12) of the box. <IMAGE>
