Abstract
An overvoltage protector for use with data cables. The protector is connected between the data cable and the piece of equipment to which the data cable is ordinarily connected. The equipment has a chassis ground. The protector includes first and second connectors for connection to the equipment and data cable, respectively as well as a protection circuit and a ground plane. The protection circuit is connected between the data cable connector, the equipment connector and the ground plane. The ground plane is in electrical connection with the conductive shell of the equipment connector. The protector is designed such that the ground plane is brought into electrical connection with the chassis ground when the protector is connected between the data cable and the equipment.
