Abstract
The present invention relates to an electromagnetic shielding device including 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), and at least one hollow connecting textile sleeve having a rest diameter D2, D2 greater than Dl. The protective textile sleeve includes a substantially annular front part having a front open end, the connecting textile sleeve includes a substantially annular rear part having a rear open end, and the shielding device includes 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.
Claims19
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 being 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 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
- wherein the protective sleeve and the connecting sleeve are secured at least partially in the first securing area by means of least one bonding means selected from the list consisting of:
- an ultrasonic welding, an electron beam welding, a friction welding, a welding by brazing, a stitching with at least one electrically conductive yarn or a combination thereof.
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 being 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 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
- wherein the front part of the protective sleeve is superimposed with the rear part of the connecting sleeve in the first securing area.
A method for manufacturing a shielding device comprising 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), at least one hollow connecting textile sleeve having a rest diameter D2, D2 being 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 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 the 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 region of a shape, said region having an outer diameter greater than or equal to D2, 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;
- (v) obtaining the shielding device, and
- step (ii) comprises the superposition, or the juxtaposition, of the front part of the protective sleeve with the rear part of the connecting sleeve.
A method for manufacturing a shielding device, wherein it 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 region of a shape, said region having an outer diameter greater than or equal to D2, 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;
- (v) obtaining the shielding device, and
- wherein the step of forming the first securing area is performed using at least one bonding means selected from the list consisting of:
- an ultrasonic welding, an electron beam welding, a friction welding, a welding by brazing, a stitching with at least one electrically conductive yarn, or a combination thereof.
