Patent ID: 8813355

Claim:
A method for producing a current metering device comprising: a current conductor comprising a middle section having a shape of a bar and two end sections comprising flattened areas, and a magnetic module for measurement of a current flowing in the current conductor via a magnetic field produced by it, comprising a bushing having one or more diameters, the method comprising: providing a magnetic module, the current conductor comprising a middle section having a shape of a bar and two end sections, and two sleeves containing copper or a copper alloy and that fit onto at least parts of the end sections of the current conductor; applying one sleeve to at least one part of one end section of the current conductor; applying the other sleeve to at least one part of the other section of the current conductor; positioning the current conductor and the magnetic module relative to one another such that the middle section of the current conductor is located with respect to the magnetic module such that the magnetic module meters the magnetic field which forms when current is flowing through the current conductor; bending the current conductor between the middle section and one end section, bending the current conductor between the middle section and the other end section, flattening the current conductor on one end section provided with one sleeve, and flattening the current conductor on the other end section provided with the other sleeve, wherein the flattening comprises producing a rectangular conductor cross section, and wherein at least one flattening is such that the longer edge length of the rectangular cross section on the ends of the current conductor is larger than the largest diameter of the bushing of the magnetic module, wherein the applying, bending, flattening and positioning steps occur in a sequence that is optional provided that each applying of a sleeve takes place prior to the respective flattening of the end section to which that sleeve has been applied.
