Abstract

The present disclosure pertains to a line connector for permanently connecting two or more electrical lines, with at least one metallic receiving sleeve which partially accommodates one of the lines, which exhibits at least a first through-opening as well as a second through-opening for introducing a welding tool or for introducing the lines, and at least a second compression section located between the through-openings, in which the receiving sleeve can be radially compressed. Furthermore, the present disclosure pertains to an electrical line assembly as well as a process for connecting two or more electrical lines.

First claim

What is claimed is:

1. A line connector assembly for connecting two or more electrical lines comprising:
at least one metallic receiving sleeve defined by two complimentary shell elements; and
a plurality of electrical lines, each electrical line including conductors surrounded by an insulating jacket,
the at least one metallic receiving sleeve including one or more fastening elements comprising projections protruding into the at least one metallic receiving sleeve for making contact with the conductors,
the at least one metallic receiving sleeve partially accommodating the plurality of electrical lines and including at least a first through-opening and a second through-opening, wherein one of the first through-opening and the second through-opening is configured for introducing a friction welding tool,
the at least one metallic receiving sleeve having at least one compression section located between the first and second through-openings, in which the at least one metallic receiving sleeve can be radially compressed,
wherein the plurality of electrical lines are materially connected to the at least one metallic receiving sleeve by the friction welding tool to form a material weld such that the conductors and the at least one metallic receiving sleeve are plasticized.

2. The line connector according to claim 1 , wherein the at least one metallic receiving sleeve includes a third through-opening having a hole axis aligned transversely to the hole axis of the first and/or second through-openings.

3. The line connector according to claim 2 , wherein the at least one metallic receiving sleeve includes a fourth through-opening having a hole axis aligned transversely to the hole axis of the first and/or second through-openings.

4. The line connector according to claim 1 further comprising two or more metallic receiving sleeves connected to one another via at least one electrically conductive connecting section.

5. The line connector according to claim 4 , wherein inner diameters of the two or more receiving sleeves are different.

6. The line connector according to claim 4 , wherein the at least one electrically conductive connecting section has a sheet-like shape.

7. The line connector according to claim 4 , wherein the at least one electrically conductive connecting section includes an electrical contact element.

8. The line connector according to claim 4 , wherein the at least one electrically conductive connecting section exhibits at least one safety fuse.

9. The line connector according to claim 1 , wherein the at least one metallic receiving sleeve tapers in from the first through-opening to the second through-opening.

10. The line connector according to claim 1 , wherein the at least one metallic receiving sleeve includes a clamping element protruding inward.

11. The line connector according to claim 1 , wherein the two complementary shell elements are connected via a coupling element, and further comprising two or more metallic receiving sleeves connected to one another via at least one electrically conductive connecting section, wherein the two complementary shell elements are located within the at least one electrically conductive connecting section.

12. The line connector according to claim 11 , wherein a sealing element is located on at least one flat surface of the at least one electrically conductive connecting section of one of the shell elements.
