Electrical connector and fuel dispensing hose with electrical conduit for a fuel dispensing system

摘要

An improved technique for providing electrical power to a fuel dispensing nozzle is disclosed. A fuel dispensing hose is provided with a fluid pathway, a vapor pathway and conductive elements are provided in the vapor pathway for transmitting intrinsically safe electric signals from a fluid dispenser to the fuel dispensing nozzle. A plurality of conductive bands are installed around a portion of the hose, and a plurality of conductive plungers in the fuel dispensing nozzle make contact with the conductive bands. As the fuel dispensing hose is twisted with respect to the nozzle, the conductive bands rotate but nonetheless remain in contact with the conductive plungers, thereby providing uninterrupted electric signals to any desired electronics installed within the fuel dispensing nozzle. On the other end of the hose, a substrate having conductive elements disposed thereon engage an aperture in the input output port of the fuel dispenser. This fragile contact is protected by stabilization bars on the hose that fit into channels of the input output port.
