Abstract
When the overall diameter of a solenoid-operated fuel injector is reduced, sections of a pair of electric terminals that are circumferentially spaced apart about, and embedded in an end wall of a bobbin of, an electromagnetic coil assembly of the fuel injector are disposed such that their rectangular transverse cross sections are disposed at an angled relation to each other to provide greater clearance to any electrically conductive parts of the fuel injector in the immediate vicinity. Other sections of the terminals that form blades of standard-sized rectangular transverse cross section for connection to terminals of a mating connector leading to an electric control circuit for operating the fuel injector are in non-angled relationship so that the mating connector and its component parts can remain of standardized dimensions.
