Abstract
A current detector comprising a current-path conductor assembly and a Hall generator assembly. The current-path conductor assembly includes a sheet-metal current-path conductor and a plastic conductor holder molded in one piece therewith. The Hall generator assembly includes a Hall generator in the form of a semiconductor chip mounted to a metal-made mounting plate, a set of leads electrically connected to the Hall generator, and a plastic encapsulation enveloping the Hall generator and parts of the leads. The Hall generator assembly and the current-path conductor assembly are combined by bonding together the encapsulation of the Hall generator assembly and the conductor holder of the current-path conductor assembly. The conductor holder and the encapsulation are shaped in interfitting relationship to each other, so that when they are united, the Hall generator is positioned to generate a Hall voltage in response to a magnetic field due to the current flowing through the current-path conductor.
