Abstract: A braking resistance device for a vehicle has a plurality of braking resistance elements each having a tubular heat-conducting casing. A heat-conducting and electrically insulating material is disposed in the casing. An electrical conductor is embedded in the insulating material over a majority of the longitudinal extent of the casing. Furthermore, the braking resistance device has a stacking arrangement which is designed to be passively cooled. The stacking arrangement has a plurality of layers which are arranged one above the other in a stacking direction and each including the braking resistance elements of the plurality of braking resistance elements which are arranged substantially parallel to one another.

Abstract: A metal corner connector contains at least two connection regions which are arranged on a lateral surface of the metal corner connector. At least one connection region is configured to be mechanically stably connected via welding to a metal pipe extending along a main extension plane of the metal corner connector. The connection region contains at least one protrusion with a groove, which is configured for receiving a welding material. The connection region has an outer surface which is adjacent to the protrusion and is configured as a contact surface for an end face of the metal pipe. A method produces a device having such a metal corner connector.
