Electrical connector and fuel dispensing hose with electrical conduit for a fuel dispensing system
First Claim
1. A fuel dispensing system comprising:
- a fuel dispensing nozzle having an electrically operated device contained therein;
a fuel dispensing hose in communication between a fuel dispenser and said nozzle, and including a first closed passageway for carrying fuel in a first direction toward said nozzle, a second closed passageway for carrying fuel vapor in a second opposite direction toward said dispenser, and means for carrying a safety-approved electrical signal between said fuel dispenser and said fuel dispensing nozzle in order to selectively provide electronic communication between said electrically operated device and said fuel dispenser, said means being disposed within one of said first and second passageways.

Abstract
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.
