This application is a U.S. National Phase application under 35 U.S.C. § 371 of International Application No. PCT/EP2020/063014, filed on May 11, 2020, and claims benefit to German Patent Application No. DE 10 2019 112 899.4, filed on May 16, 2019. The International Application was published in German on Nov. 19, 2020 as WO 2020/229392 under PCT Article 21(2).
The invention relates to a plug connector part for electrical connection to a mating plug connector part.
When an established electrical connection is disconnected, the formation of an arc is to be expected depending on an applied voltage and, in particular, in the case of direct current applications. This is often challenging particularly in the case of plug connectors. On the one hand, an arc can lead to damage to the plug connector, namely both to housing parts and to contacts. On the other hand, however, an arc can also pose a risk to an operator of the plug connector. A further topic relates to so-called stationary arcs, which can occur if an electrical connection has been separated only incompletely. In order to keep such effects as low as possible, a mechanism that allows a rapid and safe disconnection of the connection is desirable.
Pretensionable spring pins or pretensioned contact pins are described in JPH 07122332 A and DE 518012 C. Such solutions have the disadvantage that the production of such contact/spring pins is comparatively complex.

The invention claimed is:1. A plug connector part for electrical connection to a mating plug connector part, comprising:a housing, a contact carrier that is movable in relation to the housing and comprises:at least one electrical contact for the mating plug connector part, and a slider that is movable in relation to the housing and to the contact carrier, and an elastic element that is supported on the slider and on the contact carrier in such a way that the elastic element is tensionable by a displacement of the slider in relation to the contact carrier in order to bring about a displacement of the contact carrier in relation to the housing and thus to remove the contact carrier from the mating plug connector part, wherein at least one conductor connection is fixed to the housing for a firm connection of an electrical conductor, and wherein the at least one conductor connection is connectable to the at least one electrical contact on the housing by an electrically conductive element that is variable in length. 2. The plug connector part according to claim 1 , further comprising:at least one electrically conductive element configured to enable a displacement of the at least one electrical contact in relation to a conductor connection along a plug-in direction of the plug connector part. 3. The plug connector part according to claim 1 , further comprising:a locking element for locking the contact carrier to the mating plug connector part. 4. The plug connector part according to claim 3 , wherein the slider and the locking element are formed in such a way that a displacement of the slider in relation to the contact carrier first brings about tensioning of the elastic element and subsequently an actuation of the locking element. 5. The plug connector part according to claim 3 , wherein the locking element is fixed to the contact carrier. 6. The plug connector part according to claim 3 , wherein the locking element is guided in a guide of the slider. 7. The plug connector part according to claim 3 , wherein the locking element has a bevel that is configured to interact with a bevel of the slider in order to transfer the locking element from a locked position into an unlocked position. 8. The plug connector part according to claim 1 , wherein the plug connector part is pluggable into the mating plug connector part along a plug-in axis and the elastic element can be tensioned in a direction parallel to the plug-in axis. 9. The plug connector part according to claim 1 , wherein the elastic element takes the form of a spiral spring or another springy element. 10. The plug connector part according to claim 1 , wherein the contact carrier comprises a plurality of electrical contacts. 11. The plug connector part according to claim 1 , wherein the slider takes the form of a sliding sleeve and at least partially surrounds the housing and the contact carrier on the outside. 12. The plug connector part according to claim 1 , wherein the contact carrier is at least partially accommodated in the housing. 13. A plug connector, comprising:a plug connector part according to claim 1 ; and the mating plug connector part that is plug-in engageable with the plug connector part. 14. A method, comprising:separating a plug connector part from a mating plug connector part, wherein the plug connector part comprises: a housing, a contact carrier that is movable in relation to the housing and comprises: at least one electrical contact for the mating plug connector part, and a slider that is movable in relation to the housing and to the contact carrier, and an elastic element that is supported on the slider and on the contact carrier, wherein the elastic element is tensioned by a displacement of the slider in relation to the contact carrier in order to bring about a displacement of the contact carrier in relation to the housing and thus to remove the contact carrier from the mating plug connector part, wherein at least one conductor connection is fixed to the housing for a firm connection of an electrical conductor, and wherein the at least one conductor connection is connectable to the at least one electrical contact on the housing by an electrically conductive element that is variable in length. 15. A plug connector part for electrical connection to a mating plug connector part, comprising:a housing, a contact carrier that is movable in relation to the housing and comprises:at least one electrical contact for the mating plug connector part, and a slider that is movable in relation to the housing and to the contact carrier, an elastic element that is supported on the slider and on the contact carrier in such a way that the elastic element is tensionable by a displacement of the slider in relation to the contact carrier; and a locking element for locking the contact carrier to the mating plug connector part, wherein the locking element is fixed to the contact carrier.
