Method for a cable discharge apparatus for network equipment connectors

Disclosed is a method for a cable discharge apparatus for network equipment connectors.  Benefits include improved reliability.

Background

              A network cable can build up a static charge during installation and use. When the cable is plugged into network equipment, the static can discharge, permanently damaging or temporarily disabling the active components. For example, in a typical Ethernet system cable interface, a statically charged twisted pair cable with an RJ-45 connector is plugged into the receptacle of a piece of network equipment (see Figure 1). The pins of the RJ-45 do not make contact with the receptacle pins at the exact same moment. A differential voltage occurs across the isolation transformer and propagates to the physical integrated circuit (IC).

              Industry standards do not exist for the protection of components and equipment from cable discharge events (CDE).

              Conventional solutions require additional components on the printed circuit board/IC or manual (and unreliable) cable discharge discipline.

General description

              The disclosed method is a cable discharge apparatus for network equipment connectors. A conductive brush is added to the RJ-45 receptacle connectors used in local area network (LAN) cable connections. The brush may be conductive foam, spring leaf metal, or some other conductive material electrically connected to the receptacle shield groun...
