Cable junction
View Patent ↗The cable junction includes at least two electrical cables extending side by side, each including its own independent shield and a front end section where its independent shield is stripped off, a common shield surrounding the front end sections and the independent shields of the cables, and a clamping device for clamping the common shield on the independent shields. The clamping device includes internal clamping means for clamping the common shield on flanks of the independent shield sheaths.
1. A cable junction comprising:
a first electrical cable having a first wire and a first shielding means;
a second electrical cable having a second wire and a second shielding means;
an electrical connector defining a first cavity in which the first wire is received and a second cavity in which the second wire is received;
a single tubular conductive braid surrounding portions of both the first shielding means and the second shielding means and providing a flexible common shield;
a clamping device electrically connecting the tubular conductive braid to a portion of the first shielding means and a portion of the second shielding means, said clamping device surroundingly clamping the tubular conductive braid directly to internal and external flanks of the first and second shielding means; and
an electrical connector shield distinct from the tubular conductive braid and wrapped about the first and second cavity of the electrical connector, said electrical connector shield electrically connected to the tubular conductive braid.
2. The cable junction according to claim 1 , wherein the first shielding means and the second shielding means each comprise a shielding braid.
3. The cable junction according to claim 2 , wherein the first shielding means and the second shielding means each further comprises an electrically conductive sleeve surrounding the shielding braid.
4. The cable junction according to claim 1 , wherein the clamping device comprises a first wedge clamping a portion of the tubular conductive braid to internal flanks of the first and second shielding means.
5. The cable junction according to claim 4 , wherein the clamping device comprises a second wedge introduced between the internal flanks of the first and second shielding means and wherein the first and second wedges point toward each other.
6. The cable junction according to claim 1 , wherein the tubular conductive braid is made of a braided sheet that is folded onto itself with a lateral overlap.
7. The cable junction according to claim 1 , wherein the tubular conductive braid is made of a continuous braided cylinder.
8. The cable junction according to claim 1 , further comprising two insulating rings fixed at respective ends of the tubular conductive braid.
9. The cable junction according to claim 8 , wherein the insulating ring at an end of the tubular conductive braid is provided with, at rest, two opposite bulges configured to be introduced between the internal flanks of the independent shields.
10. The cable junction according to claim 1 , further comprising an insulating sheath covering the tubular conductive braid.
11. The cable junction according to claim 1 , further comprising, for each cable, an insulating tubular finger projecting rearward from the rear end of the tubular conductive braid and stretched around the respective cable.
12. The cable junction according to claim 1 , wherein the clamping device is arranged transversely to the first and second electrical cable.
13. The cable junction according to claim 12 , wherein the clamping device comprises a half clamp defining a first semi-cylindrical opening clamping the tubular conductive braid to internal and external flanks of the first shielding means and a second semi-cylindrical opening clamping the tubular conductive braid to internal and external flanks of the second shielding means.
14. The cable junction according to claim 13 , wherein the clamping device comprises two half clamps, wherein the first semi-cylindrical openings surroundingly clamp the tubular conductive braid to the internal and external flanks of the first shielding means and wherein the second semi-cylindrical openings surroundingly clamp the tubular conductive braid to the internal and external flanks of the second shielding means.
15. The cable junction according to claim 14 , wherein the clamping device further comprises an external clamping means surroundingly clamping the two half clamps to the tubular conductive braid.
