Patent ID: 7936164

Claim:
A current sensor comprising: a soft ferromagnetic body forming a lumen configured to receive a conductor, the soft ferromagnetic body having first and second folding portions configured to fold, unfold, and to enclose the conductor within the lumen; and a magnetic field detector having at least a portion disposed within a gap extending along at least a portion of a longitudinal length of the soft ferromagnetic body when the first and second folding portions are folded, a first surface of the magnetic field detector in contact with a surface of a first extension of the first folding portion, the first extension extending from a longitudinal surface of the first folding portion within the gap leaving an area of the longitudinal surface of the first folding portion within the gap uncovered, and a second surface of the magnetic field detector opposing the first surface of the magnetic field detector in contact with a surface of a second extension of the second folding portion, the second extension extending from a longitudinal surface of the second folding portion within the gap leaving an area of the longitudinal surface of the second folding portion within the gap uncovered.
