Fixed inductance bobbin for launcher with solenoid induction, and launcher with solenoid induction with such a bobbin

摘要

The coil includes the hollow mandrel (1) made from isolating material with layers of spiral wound conductors (8) of the same length, and a device for connecting between the conductors (8) and an electric supply of the coil. Each winding is isolated from the next and angularly separated, and enmeshed with the other conductors. The conductors form a first (7a) and a second (7b) winding around the same axis (3), one of the free ends of each conductor (8) being accessible on the external perimeter (21) of the first winding (7a), and the other free end of the conductor (8) being accessible on the external perimeter (21b) of the second winding (7b).
