Electronic device security with cross-talk reduction between connector ports

An electronic device comprises a means for reducing cross-talk between ports via a connector shield 300. Electronic circuitry is enclosed within a housing and a plurality of ports are provided for connecting electrical devices to the electronic device. Each port includes a connector (e.g. a D-type c...

description	An electronic device comprises a means for reducing cross-talk between ports via a connector shield 300. Electronic circuitry is enclosed within a housing and a plurality of ports are provided for connecting electrical devices to the electronic device. Each port includes a connector (e.g. a D-type connector) which is connected by at least one electrical connection 234, 236 to the electronic circuitry. Each port also includes a connector shield 300 which is arranged to provide an electrically conductive loop, around which an induced electrical current can flow, thereby reducing cross-talk between ports. The connector shield 300 is formed from a foldable blank 360 of electrically conductive material (e.g. nickel coated silver) to create a shielding can. An electrical contact electrically connects the body of the shielding can to the connector. A face 364 of the body of the shielding can defines a first aperture 374 shaped to receive the connector so that the shielding can may be arranged about the connector to form a part of the electrically conductive loop.
