Electromagnetic shielding device

A shielding device comprising,

• a. At least one hollow protective textile sleeve having a main rest diameter D1 and an interior volume configured to receive one or several elongated element(s),
• b. At least one hollow connecting textile sleeve having a rest diameter D2, D2 greater than D1,
• wherein the protective textile sleeve comprises a substantially annular front part having a front open end, the connecting textile sleeve comprises a substantially annular rear part having a rear open end, and the shielding device comprises a first electrically conductive, at least partially annular, securing area in which the rear part of the connecting sleeve and the front part of the protective sleeve are at least partly secured;
• wherein first securing area comprises three or four textile layers secured in their thicknesses in an electrically conductive manner, including at least two textile layers of the protective textile sleeve, and at least one textile layer of the connecting sleeve.

A method for manufacturing an electromagnetic shielding device comprising

• a. At least one hollow protective textile sleeve having a main rest diameter D1 and an interior volume configured to receive one or several elongated element(s),
• b. At least one hollow connecting textile sleeve having a rest diameter D2, D2 greater than D1,
• wherein the protective textile sleeve comprises a substantially annular front part having a front open end, the connecting textile sleeve comprises a substantially annular rear part having a rear open end, and the shielding device comprises a first electrically conductive, at least partially annular, securing area in which the rear part of the connecting sleeve and the front part of the protective sleeve are at least partly secured,
• wherein said method comprises:
• (i)—a step of disposing a hollow protective textile sleeve having an outer rest diameter D1 and an interior volume configured to receive one or several elongated member(s), and comprising a substantially annular front part having a front open end, on at least one expansion device, causing the expansion at least of the substantially annular front part of the protective sleeve according to an outer diameter D1′ substantially equal to D2;
• (ii)—a step of providing a hollow connecting textile sleeve having a main rest diameter D2, D2 being greater than D1, and a substantially annular rear part having a rear open end, and a step of contacting the rear part of the connecting sleeve with the front part of the protective sleeve;
• (iii)—a step of forming a first electrically conductive securing area, in which the rear part of the connecting sleeve and the front part of the protective sleeve are at least partly secured;
• and
• (v) obtaining the shielding device;
• and
• wherein step (ii) comprises the superposition, or the juxtaposition, at least partial, of the front part of the protective sleeve with the rear part of the connecting sleeve.
