1. A half-bridge for an electric drive for an electric vehicle or hybrid vehicle, comprising:
a substrate;
semiconductor switch elements;
power connections; and
signal connections;
wherein the power connections and the signal connections are formed in a flat conductor frame,
wherein the signal connections are electrically connected to the semiconductor switch elements such that the semiconductor switch elements can be switched via the signal connections,
wherein the power connections are electrically connected to the semiconductor switch elements such that the semiconductor switch elements allow or interrupt electricity transfer between the power connections,
wherein the semiconductor switch elements, signal connections, and power connections are located on a first surface of the substrate and cast in a casting compound,
wherein first end sections of the signal connections formed in the flat conductor frame each extend from a second surface of the substrate that is orthogonal to the first surface, exiting the casting compound, wherein second end sections of the signal connections, which are separate from the flat conductor frame, are connected to the first end section of the signal connections outside the casting compound, such that the second end sections are perpendicular to the first surface, and
wherein holes are formed in the first end sections of the signal connections, in which the second end sections of the signal connections are inserted.
