Elbow connection for multiple-wire electric cable
View Patent ↗This invention relates to an elbow connection ( 10 ) for an electric cable ( 6 ) with several wires ( 5 ). According to the invention, the connection ( 10 ) comprises a fluted central carrier ( 1 ) running longitudinally (L), made up of a flexible stem ( 2 ), comprising several substantially parallel recesses ( 4 ), and a strengthening rod ( 3 ), arranged at the core of the stem ( 2 ) and suitable for being bent.
1. An elbow connection for an electric cable with plural wires, comprising:
a longitudinal fluted central carrier, including
a flexible stem which is bent and made of a flexible material,
plural longitudinal recesses spaced circumferentially on the surface of the stem,
a strengthening rod which is bent and arranged axially at a core of the stem in a longitudinal direction, and
wire holding elements for peripheral holding of wires in the recesses,
wherein the wire holding elements include a barrel comprising plural housings formed parallel with a center-line and corresponding to an extension of the recesses, respectively, of the stem.
2. The elbow connection according to claim 1 , wherein the strengthening rod is a rigid metal rod.
3. The elbow connection according to claim 1 , wherein the stem is made of a silicone based material.
4. The elbow connection according to claim 1 , wherein the stem includes a substantially cylindrical geometry in the longitudinal direction.
5. The elbow connection according to claim 1 , wherein the stem includes a slightly decreasing section in the longitudinal direction.
6. The elbow connection according to claim 1 , wherein each recess has a cross section in an arc of a circle of a diameter D.
7. The elbow connection according to claim 6 , wherein each of the plural longitudinal recesses comprises, on a surface of the stem, an opening of width smaller than a diameter of the recess.
8. The elbow connection according to claim 1 , wherein an axial part of a barrel comprises an axial hole for anchoring the strengthening rod.
9. The elbow connection according to claim 8 , wherein the axial hole of the barrel and/or the strengthening rod includes a screw thread or screw threads.
10. The elbow connection according to claim 1 , wherein the wire holding elements comprise an annular ring of a diameter greater than the stem.
11. The elbow connection according to claim 1 , wherein the wire holding elements comprise at least one shielding braid.
12. The elbow connection according to claim 1 , wherein the wire holding elements comprise at least one layer of peripheral sheathing laid on the wires.
13. The elbow connection according to claim 1 , wherein the wire holding elements comprise an external sheathing sleeve.
14. The elbow connection according to claim 12 , wherein the sheathing is heat shrinkable.
15. The elbow connection according to claim 1 , further comprising a mechanical coupling part.
16. A connector for an electric cable, comprising an elbow connection according to claim 1 .
17. An electric cable, comprising at least one elbow connection according to claim 1 .
18. An electric cabling harness comprising at least one elbow connection according to claim 1 .
19. The elbow connection according to claim 1 , wherein the stem is configured to be molded directly onto the strengthening rod.
