2. The high-voltage connector of claim 1 , wherein the upper part further includes a plurality of ground terminals connected to the plurality of spring elements.

3. The high-voltage connector of claim 2 , wherein each ground terminal includes a central contact portion connected to a pair of the spring elements, wherein the spring elements are arranged at an angle which is oriented tangentially and radially to an outer circumference of the connector socket, and

wherein when the upper part is axially connected to the connector socket, the spring elements engage the connector socket with a predefined spring force.

4. The high-voltage connector of claim 3 , wherein the central contact portion of the ground terminal is connected to an external contact terminal arranged outside the upper part.

5. The high-voltage connector of claim 4 , wherein at least two of the ground terminals are positioned in a radially opposing arrangement.

6. The high-voltage connector of claim 1 , wherein the connector socket includes a locating bevel which conically extends toward an upper end of the connector socket and a cylindrical portion arranged beneath the locating bevel, the cylindrical portion of the connector socket being configured to contact the plurality of spring elements.

7. The high-voltage connector of claim 6 , wherein the connector socket further includes a lower region having an outer diameter larger than an outer diameter of an upper region of the connector socket, and

wherein the upper region of the connector socket has an inner diameter larger than an inner diameter of the lower region of the connector socket such that an inner diameter of the lower part is stepped.

8. The high-voltage connector of claim 1 , wherein the lower part has an outer diameter including two axially stepped regions, which engage with an internal diameter of the connector socket in a form-fitted manner,

wherein the lower part includes an annular portion at an upper end thereof, which cooperates with the upper end of the connector socket, and

wherein the lower part further includes at least two hook clamps at a lower end thereof, for attachment to the connector socket in a snap-fit arrangement.

9. The high-voltage connector of claim 8 , wherein the lower part includes a continuous axial bore extending along a lower portion and an upper portion of the lower part, the continuous axial bore having a diameter in the lower portion of lower part corresponding to an external diameter of the lower pin, and

wherein a diameter of the continuous axial bore in the upper portion of the lower part is larger than the diameter of the continuous axial bore in the lower portion of the lower part.

10. The high-voltage connector of claim 1 , wherein the lower pin is fitted within a continuous axial bore of the lower part in a plug-in arrangement such that an upper end of the lower pin is flush with an upper end of the lower part, and a lower end of the lower pin projects outwardly from a lower end of the lower part, and

wherein the upper end of the lower pin includes a connecting portion for connecting to the upper pin and the lower portion of the lower pin includes a contact tip configured to connect to an electrode.

11. The high-voltage connector of claim 1 , wherein the upper part further includes an inner socket extending from the base and positioned axially within the outer cylindrical wall and an open end opposite the base.

12. The high-voltage connector of claim 1 , wherein lower ends of the spring elements are configured to extend in an axial direction and terminate at a position below a lower end of the upper pin when the upper pin is positioned within the upper part such that as the upper part is connected to the connector socket, the spring elements are configured to form a ground connection via the connector socket prior to a high-voltage connection being formed by a high-voltage transformer via the upper pin, and as the upper part is withdrawn from the connector socket, the high-voltage connection is interrupted prior to an interruption of the ground connection.
