(57) An improved surge protection for protecting an electronic device is disclosed, the
device having a closed casing with walls made of a non-conducting material and being
internally coated with a thin metallic layer. The device also has at least one connector,
being arranged in an opening in the walls and including a connector body, at least
a portion of which projects outwardly from the wall and which accommodates an internal
coupling device, to which a transmission cable, including a central conductor and
an outer shield conductor, is connectable. According to the invention, the connector
body is also made of a non-conducting material and strong currents, being present
at a conducting protection sleeve, are diverted by at least one conducting diversion
member to at least one metallic structure, being in permanent electric contact with
ground and having a high capacity of conducting strong currents. In use, the at least
one conducting diversion member is in electrical contact with the protection sleeve,
and extends radially outwardly from the protection sleeve, through the connector body,
to the at least one metallic structure.
