Abstract

An electrical connector for a multi-wire electrical cable includes at least two cable-side electrical contact elements including associated electrical terminals to each of which is to be connected a wire of the electrical cable. At least two output-side electrical contact elements, from each of which projects an electrical connector element by which an electrical connection can be established to a mating connector. An electrically conductive carrier body is disposed between the cable-side contact elements and the output-side contact elements. The electrically conductive carrier body carries an electrical device by which the cable-side contact elements and the output-side contact elements are electrically connected to each other. The electrical device is supported by the carrier body without any of the cable-side contact elements or the output-side contact elements being in electrical contact with the carrier body through the electrical device.

Claims

1. An electrical connector for a multi-wire electrical cable, the electrical connector comprising:

at least two cable-side electrical contact elements including associated electrical terminals to each of which is to be connected a wire of the electrical cable;

at least two output-side electrical contact elements, from each of which projects an electrical connector element by which an electrical connection is establishable to a mating connector; and

an electrically conductive carrier body disposed between the cable-side contact elements and the output-side contact elements, the electrically conductive carrier body carrying an electrical device by which the cable-side contact elements and the output-side contact elements are electrically connected to each other, the electrical device being supported by the carrier body without any of the cable-side contact elements or the output-side contact elements being in electrical contact with the carrier body through the electrical device.

2. The electrical connector as recited in claim 1, wherein the carrier body forms a support region which extends from a first connecting section to a second connecting section, the electrical device being disposed on the support region, and wherein a supporting section of the carrier body extends from each of the two connecting sections in such a way that the support region and the two supporting sections form a ring-shaped circumferential structure.

3. The electrical connector as recited in claim 2, wherein the two supporting sections each extend along an arcuate path.

4. The electrical connector as recited in claim 2, wherein the two supporting sections each have a free end, and wherein the free ends of the supporting sections face each other.

5. The electrical connector as recited in claim 4, wherein the free ends of the supporting sections are spaced apart.

6. The electrical connector as recited in claim 2, wherein the carrier body is formed as a single piece, and the supporting sections are configured by bending to form an annular contour.

7. The electrical connector as recited in claim 1, wherein the electrical device is electrically connected by wires to the cable-side contact elements and to the output-side contact elements.

8. The electrical connector as recited in claim 1, wherein each of the wires of the electrical cable is connected to a respective one of the cable-side contact elements.

9. The electrical connector as recited in claim 1, further comprising an outer conductor which encloses an interior space of the electrical connector, the carrier body, the cable-side contact elements and the output-side contact elements being at least partially disposed in the interior space, and the outer conductor being fixed to the carrier body.

10. The electrical connector as recited in claim 9, wherein the outer conductor is fixed to the carrier body in a form-fitting manner and/or by a material-to-material bond.

11. The electrical connector as recited in claim 9, wherein the carrier body partially extends out of the outer conductor through first slots of the outer conductor.

12. The electrical connector as recited in claim 11, wherein the carrier body forms a support region which extends from a first connecting section to a second connecting section, the electrical device being disposed on the support region, wherein a supporting section of the carrier body extends from each of the two connecting sections in such a way that the support region and the two supporting sections form a ring-shaped circumferential structure, wherein the support region of the carrier body, together with the electrical device, is located within the interior space enclosed by the outer conductor, and wherein the carrier body extends out of the outer conductor at the connecting sections.

13. The electrical connector as recited in claim 12, wherein the supporting sections of the carrier body enclose an outer side of the outer conductor.

14. The electrical connector as recited in claim 1, wherein the cable-side contact elements, the output-side contact elements and the carrier body are separate, spaced-apart components.

15. The electrical connector as recited in claim 1, wherein the cable-side contact elements, the output-side electrical contact elements and the carrier body for the electrical device are manufactured as parts of a single, integrally formed component.

16. The electrical connector as recited in claim 15, wherein the single, integrally formed component is in the form of a stamped conductor pattern.
