Hall-effect current detector
First Claim
1. A current detector utilizing the Hall-effect for detection or measurement of electric current, comprising:
- (A) a current-path conductor assembly comprising;
(a) a current-path conductor for carrying the current to be detected or measured; and
(b) a conductor holder of electrically insulating material integrally enveloping part of the current-path conductor, the conductor holder having a positioning recess;
(B) a Hall generator assembly comprising;
(a) a Hall generator for generating a Hall voltage proportional to the strength of an applied magnetic field;
(b) a plurality of leads electrically connected to the Hall generator; and
(c) an encapsulation of electrically insulating material integrally enveloping the Hall generator and parts of the leads, the encapsulation having a size which can be put into the positioning recess; and
(C) the current-path conductor assembly and the Hall generator assembly being combined by joining together the conductor holder of the current-path conductor assembly and the encapsulation of the Hall generator assembly, with the current-path conductor disposed adjacent the Hall generator in order to cause the Hall generator to generate the Hall voltage in response to a magnetic field due to the current flowing through the current-path conductor, the encapsulation being put into the positioning recess of the conductor holder.

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.
