Inductance coil fabricating process for e.g. transformer, involves connecting ends of turns of one branch with other branch of jumper on entire extension of magnetic core by narrow paths ensuring continuous electrical connection of turns

摘要

The process involves forming each one of turns of a winding of an inductance coil in the form of a jumper. The jumper has a median part (5) overlapping a magnetic core and two branches (6, 7) traversing drillings (8) of a printed circuit board (1). Respective ends (9, 10) of the turns of one branch are connected with the other on the entire extension of the core by narrow paths (11) ensuring continuous electrical connection of the turns. An independent claim is also included for an inductance coil.
