Abstract

An electrical connector configured to be mated to a mating connector includes a housing assembly and a core assembly held rotatably within the housing assembly. The core assembly includes a contact assembly having a contact configured to electrically contact a mating contact of the mating connector, a finger protection assembly configured to at least partially cover the contact assembly, and a cable retention assembly configured to be attached onto an electrical cable.

First claim

What is claimed is:

1. An electrical connector configured to be mated to a mating connector, comprising:
a housing assembly; and
a core assembly held rotatably within the housing assembly, the core assembly including a contact assembly having a contact configured to electrically contact a mating contact of the mating connector, a finger protection assembly configured to at least partially cover the contact assembly, and a cable retention assembly configured to be attached onto an electrical cable.

2. The electrical connector of claim 1 , wherein the finger protection assembly has an outer protection element surrounding the contact and a front protection element covering a front part of the contact.

3. The electrical connector of claim 1 , further comprising a locking structure locking the core assembly to the housing assembly.

4. The electrical connector of claim 3 , wherein the locking structure blocks a translational relative movement between the core assembly and the housing assembly.

5. The electrical connector of claim 4 , wherein the locking structure has a pair of locking elements engaging one another, one of the locking elements is a circumferential groove and the other one of the locking elements is a form-fit element extending into the circumferential groove.

6. The electrical connector of claim 5 , wherein the form-fit element is formed on one of the housing assembly and the core assembly and the circumferential groove is formed on the other of the housing assembly and the core assembly.

7. The electrical connector of claim 6 , wherein the locking element of the core assembly is located on the cable retention assembly.

8. The electrical connector of claim 1 , wherein the core assembly has a shield sleeve in which the contact assembly, the finger protection assembly, and the cable retention assembly are at least partially received.

9. The electrical connector of claim 8 , wherein the shield sleeve has a radially inwardly protruding section engaging with one of the finger protection assembly and the cable retention assembly.

10. The electrical connector of claim 8 , wherein the shield sleeve has a radially outwardly protruding section engaging with the housing assembly.

11. The electrical connector of claim 8 , wherein the shield sleeve forms an outer hull of the core assembly.

12. The electrical connector of claim 1 , wherein the cable retention assembly has a cable fixation sleeve configured to radially abut against a cable insulation of the electrical cable.

13. The electrical connector of claim 12 , wherein the cable retention assembly has a shield support sleeve configured to support a shield of the electrical cable.

14. The electrical connector of claim 13 , wherein the shield support sleeve is arranged between the cable fixation sleeve and the finger protection assembly.

15. The electrical connector of claim 13 , wherein the cable retention assembly has a sealing device arranged between the cable fixation sleeve and the shield support sleeve.

16. The electrical connector of claim 1 , wherein the housing assembly includes a connector housing through which a receptacle for receiving the electrical cable extends along a mating direction.

17. The electrical connector of claim 16 , wherein the connector housing has a rotationally asymmetric outer contour with respect to the mating direction.

18. The electrical connector of claim 17 , wherein the rotationally asymmetric outer contour derives from at least one of a rotationally asymmetric locking feature, a rotationally asymmetric coding feature, a rotationally asymmetric grounding feature, and a rotationally asymmetrically arranged circuitry element.
