Patent ID: 8854785

Claim:
A surge protection arrangement, for protecting an electronic device provided with a closed casing, said casing including side and bottom walls made of a non-conducting material and being internally coated with a thin metallic layer, and at least one connector formed integral with the closed casing, being arranged in an opening in one of said walls and including a connector body, at least a portion of which projects outwardly from said wall and which accommodates an internal coupling device, to which a transmission cable, including a central conductor and an outer shield conductor, is connectable, wherein said connector body is made of a non-conducting material, said connector body is essentially cylindrical and radially surrounds said internal coupling device, and said internal coupling device includes a conducting protection sleeve, in use being in electrical contact with said outer shield conductor of said transmission cable, and at least one conducting diversion member, in use being in electrical contact with said protection sleeve, and extending radially outwardly from said protection sleeve, through said connector body, electrically bypassing the thin metallic layer on the casing interior to at least one metallic structure being in permanent electric contact with ground and having a high capacity of conducting strong currents.
