FOLDING CURRENT SENSOR
First Claim
1. 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 to enclose the conductor within the lumen; and
a magnetic field detector having at least a portion disposed within the first and second folding portions.

Abstract
The invention provides a current sensor that may be folded over a conductor without the need to sever the conductor or thread the conductor through the current sensor. In one embodiment, the current sensor includes an outer body having a first folding portion and a second folding portion coupled to the first folding portion. The current sensor also includes a soft ferromagnetic body disposed within the outer body comprising a first core element and a second core element. The first and second core elements form a lumen when the first and second folding portions are folded. The lumen is configured to receive a conductor. The current sensor also includes a magnetic field detector to sense a current in the conductor. The magnetic field detector is disposed at least partially between the first and second core elements when the first and second folding portions are folded.

23. A current sensor for sensing current in at least one loop of a conductor comprising:
-
an outer body having a first folding portion and a second folding portion, the first and second folding portions rotatably coupled by at least one rotator element; a soft ferromagnetic core comprising a first core element disposed in the first folding portion of the outer body, and a second core element disposed in the second folding portion of the outer body, such that when the first and second folding portions are folded at the rotator element, the first and second core elements form a lumen to receive the at least one loop of the conductor; and a magnetic field detector disposed at least partially within the outer body and, when the first and second folding portions are folded at the at least one rotator element, the magnetic field detector further disposed at least partially between the first and second core elements. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
