Abstract:
1. A current sensor having a magnetic gap, the current sensor comprising: a first case segment having a terminal; a second case segment coupled to the first case segment at a first joining surface of the first case segment and a second joining surface of the second case segment to provide a main body; an opening in the main body, the opening extending from the first case segment to the second case segment, a conductive material capable of being inserted in the opening; an element mounting portion arranged on the first joining surface, and an end portion of the terminal being exposed in the element mounting portion; a first magnetic sensing element mounted on the element mounting portion, and electrically coupled with the terminal; a core holding portion in the main body, the core holding portion surrounding the opening in the main body and the element mounting portion; and a core having the magnetic gap, the core being held in the core holding portion, wherein the magnetic sensing element is arranged on the element mounting portion in the magnetic gap of the core, wherein the core is integrally formed and has a C-shape, and wherein the second joining surface has a concave portion, and the magnetic sensing element is located in a space defined by the element mounting portion and the concave portion when the second case segment is coupled to the first case segment.
