Accordingly, a plug connector part is provided for electrical connection to a mating plug connector part and for safe separation from the mating plug connector part, wherein the plug connector part comprises a housing, a contact carrier, a slider, and at least one elastic element. The contact carrier comprises at least one electrical contact for the mating plug connector part and is mounted movably in relation to the housing, for example movably on the housing. The slider is mounted movably in relation to the housing and in relation to the contact carrier, for example movably on the housing in such a way. The elastic element is supported on the slider and on the contact carrier such that it can be tensioned by a displacement of the slider in relation to the contact carrier (in particular, in a spring-elastic manner) in order to bring about a displacement of the contact carrier in relation to the housing.

In this way, a plug connector part is provided, which is improved, in particular, to the effect that it is thus possible to ensure a rapid and safe disconnection of a connection with the corresponding mating plug connector part independently of external influences or a user of the plug connector part. The electrical connection is disconnected by moving the contact carrier in relation to the housing as a result of the (pre)tension of the elastic element. Therefore, the user can hold the housing in his hand during the separation without impairing the separation. Thus, damage or injuries due to an arc can be avoided particularly reliably. The plug connector part comprises three components that can be moved in relation to one another, namely the housing, the contact carrier, and the slider. A tensioning of the elastic element takes place, for example, by compression or stretching.
