Abstract

Aspects of the present invention include a method and apparatus for an improved USB device having ESD protection. Uniquely including and positioning a discharge plane of a low resistance within a USB connection that is connectable with the ground of the USB connector, creates a discharge gap area where excess ESD charge may jump and discharge prior to the connection of paired USB devices having connectable connections.

Claims (10)

1. An apparatus comprising:

USB device having a USB connector and a discharge plane of a low resistance, having a proximate end and a distal end, configured internally to the USB connector wherein one of the distal end or the proximate end is connectable with a ground signal of the USB connector and the axial planar length of the plane is less than the connection planar length of the USB connector, wherein the USB connector is connected with a USB cable, wherein the USB connector is a USB socket capable of receiving a USB plug, the connector having an upper connection portion and a lower connection portion having signal lines, wherein the plane is arranged between the upper connection and the lower connection portion, the distal end is connected with the ground signal, and the proximate end is arranged to be exposed towards the lower connection portion, wherein an exposed air-gap area is formed between a middle connection and the lower connection, and any excess ESD charge may jump and discharge the air-gap area prior to the connection of the USB connector.

2. The apparatus of claim 1 wherein the USB connector is a USB plug capable of being received by a USB socket, the plug having an upper connection portion and a lower connection portion having signal lines, wherein

the plane is arranged between the upper connection and the lower connection portion,

the distal end is in temporary contact with the ground signal, and

the proximate end is fixedly arranged with the upper connection portion.

3. The apparatus of claim 2 wherein the distal end is flexibly arranged where the connector can connect with a USB-paired socket and then return to a predetermined original position upon the connector and socket disengaging.

4. The apparatus comprising a USB connector having an internal discharge plane configurably arranged internal to an upper connection portion and a lower connection portion of the connector, wherein a proximate end of the plane is affixed with the upper connection portion at a predetermined distance from a proximate end of the connector to enable a discharge of static energy prior to the USB connector being connected with a USB-paired connection counterpart, wherein an exposed air-gap area is formed between a middle connection and the lower connection, and any excess ESD charge may jump and discharge the air-gap area prior to the connection of the USB connector.

5. The apparatus of claim 4 further comprising a USB cable in operative communication with the connector, wherein a distal end of the plane is flexibly grounded with a ground of the lower connection portion of the connector.

6. The apparatus of claim 5 , further comprising a USB-paired connection counterpart connectably arranged with the connector, wherein the distal end of the plane is connected from ground.
