Definitions

  • connection pads 1, 2 are identical. Their shape appears more clearly in Figure 3. Each of them consists of a metal tongue folded in a U shape with two wings 11, 12 of different profile and height joined by a base 13.
  • the largest wing 11 1 is flush with the surface of a lateral face of the parallelepiped of which it occupies the lower half over the entire width. It is of substantially rectangular profile with in the middle of its top, a large rounded notch 14 ensuring the release of the access orifices 7 and 8 to the interior volume of the winding 5, and, on the side of its top a finger 15 which is folded towards the other wing and on which is fixed one end of the winding 5.
  • the smallest wing 12 also has a rectangular profile.
