Claim 30:
31. A manufacturing method for a current measuring resistor, comprising the following steps:
a) providing a first connection part comprising a conductor material for introducing an electric current into the current measuring resistor,
b) providing a second connection part comprising a conductor material for conducting the electric current out of the current measuring resistor,
c) providing a resistor element comprising a low-resistance resistance material,
d) joining the resistor element to the first and second connection parts to form the current-measuring resistor, so that the resistor element is arranged in a direction of current flow between the first connection part and the second connection part and the electric current to be measured flows through the resistor element during operation and generates a voltage drop across the resistor element,
e) mounting a printed circuit board for measuring the voltage drop across the resistor element on an outer surface of the resistor element,
f) mounting a housing on the current measuring resistor, the housing enclosing; the resistor element,
g) inserting at least one measuring card into the housing, the measuring card measuring the voltage drop across the resistor element,
h) mounting of at least one coil for energy harvesting from a magnetic field of the current measuring resistor by energy harvesting, and
i) mounting of a housing cover on the current measuring resistor,
j) wherein the first connection part, the second connection part and the resistor element each have a substantially round cross-section in a sectional plane at right angles to the direction of current flow.
