Abstract

A cable includes an electric line having a plurality of cores with contacts being attached to ends of the cores. A plug connector has a contact carrier which accommodates the contacts in such a manner that the contacts are disposed in the contact carrier with a directional component that is oriented in parallel to a first direction. A collar is integrally formed on the contact carrier. The collar fixes the electrical line in position and bends the cores such that the cores have a directional component that is oriented in parallel to a second direction. The first direction is orthogonal to the second direction.

First claim

What is claimed is:

1. A cable comprising:
an electric line having a plurality of cores and an insulating sheath;
contacts attached to ends of the cores;
a plug connector having a contact carrier with an integral design which accommodates the contacts in such a manner that the contacts are disposed in the contact carrier with a directional component that is oriented in parallel to a first direction, the plug connector having an extrusion coating and the cores being at least partially surrounded by the extrusion coating; and
a collar integrally formed on the contact carrier, the collar fixing the electrical line in position and bending the cores such that the cores have a directional component that is oriented in parallel to a second direction, the first direction being orthogonal to the second direction, the collar having a stop against which an end side of the insulating sheath abuts.

2. The cable as recited in claim 1 , wherein the collar is at least partially surrounded by the extrusion coating.

3. The cable as recited in claim 1 , wherein the insulating sheath is removed at an end of the electric line and the cores are surrounded by the extrusion coating over a length of the electric line along which the insulating sheath is removed.

4. The cable as recited in claim 1 , wherein the insulating sheath is fixed in position at the collar.

5. The cable as recited in claim 4 , wherein the insulating sheath is clampingly fixed in position at the collar.

6. The cable as recited in claim 1 , wherein the cores have different lengths.

7. The cable as recited in claim 1 , wherein a crimping connects the contacts to the cores.

8. A method for manufacturing a cable having a plug connector, the method comprising:
preparing an electric line having a plurality of cores and an insulating sheath;
attaching contacts to ends of the cores;
inserting the contacts into an integral contact carrier in such a manner that the contacts are disposed in the contact carrier with a directional component that is oriented in parallel to a first direction;
securing the electric line to a collar that is integrally formed on the contact carrier such that the collar bends the cores to have a directional component that is oriented in parallel to a second direction, the first direction being orthogonal to the second direction, the collar having a stop against which an end side of the insulating sheath abuts; and
extrusion coating the cores such that the cores are at least partially surrounded by an extrusion coating.

9. The method as recited in claim 8 , wherein the extrusion coating is implemented in such a way that the collar is at least partially surrounded by the extrusion coating.

10. The method as recited in claim 8 , wherein the contacts are attached to the ends of the cores using a crimping process.

11. The method as recited in claim 8 , wherein the insulating sheath is removed at an end of the electric line such that an end face-side surface of the insulating sheath is produced at the end side and used as a reference for a cutting-to-length of the cores.

12. The method as recited in claim 8 , wherein the cores have different lengths.
