Abstract: A contact-protected screw-connection has a male screw connector and a female screw connector. The male screw connector has a connecting screw, which extends along a longitudinal axis in a screw direction towards the female screw connector and is screwed into a nut portion of the female screw connector. The connecting screw has a connecting-screw head, and the connecting screw extends along the longitudinal axis through a first electrical conductor. The connecting-screw head is arranged on a side of the first electrical conductor that is directed away from the nut portion. The male screw connector has a first protective cover, which encloses the connecting-screw head at a radial distance therefrom. The female screw connector has a second protective cover. The nut portion extends from a second electrical conductor, in the direction counter to the screw direction towards the first electrical conductor.

Abstract: A locking device for an energy storage device of a motor vehicle, includes a locking element, which is adjustable based on a control signal, by an adjusting device between a locking position, in which the locking element engages with a latch receptacle, and a release position, in which the locking element is out of engagement with the latch receptacle. The adjusting device has an adjusting element made of a shape memory alloy. The shape change enables the locking element to be adjustable between the locking position and the release position.
