The sudden movement of the contact carrier 21 quickly removes the electrical contacts 210 of the plug connector part 2 from the electrical contacts 31 of the mating plug connector part 3 in such a way that the burning time of an arc is significantly reduced. In particular, a stationary arc is effectively avoided. In this respect, it is insignificant how quickly a user pulls on the sliding sleeve 22, because the separating pulling movement of the electrical contacts 210 of the plug connector part 2 takes place by means of the elastic elements 23 as soon as the locking is released. During this pulling movement, the position of the housing 20 of the plug connector part 2 in relation to the mating plug connector part 3 can initially remain unchanged. This has the advantage that whether or not a user holds the housing 20 with his other hand when pulling it on the sliding sleeve 22 is also irrelevant. Furthermore, this embodiment makes it possible for the plug connector 1 to be safely usable even in the case of very restricted space conditions.

It is also worth mentioning that the elastic elements 23 are not tensioned (compressed) when the plug connector part 2 is plugged onto the mating plug connector part 3.
