Electrostatic Eliminators for Connector Cables

An eliminator pad for discharging electrostatic charges from cables to data processing systems can be made by suspending conductive particles in an elastomer base and fastening the pad next to the conductor plug.

Device interface cables, when not connected to an active device, will accumulate an electrostatic charge. The charge can intensify as cables are dragged across computer room floors. When the cables are attached, the charge can discharge through the logic drivers potentially causing damage.

The eliminator pad is constructed of a composite of particles of an electrically conductive material, such as silver, nickel or carbon suspended in a silicon elastomer base. A soft and pliable pad results that is electrically conductive. The pad is mounted to the device frame adjacent to the cable plug connectors such that the pad is essentially at earth ground. Before the cable is connected to the plug connectors, the cable plug is touched to the pad to discharge any electrostatic charge in the plug pins. The soft pad protects the pins from physical damage while discharging the charge to the frame.
