摘要： A method for producing a device for measuring current strengths. The method includes providing a resistor arrangement with two connection elements and a resistor element arranged between the connection elements, molding a contact element from the material of the connection element or from the material of the resistor element. The contact element has an end face remote from the resistor arrangement and a cavity open on the end face. The method further includes providing a circuit board with a through-bore on whose inner surface electrically conductive material is present, positioning the circuit board on the resistor arrangement such that the contact element projects into the through-bore, and expanding the contact element in the radial direction using an expansion element inserted into the cavity of the contact element to establish an electrically conductive connection between the contact element and the electrically conductive material on the inner surface of the through-bore.
