| 主权项 | 1. A current sensor comprising: a lower housing; a lower magnetic core that is housed in the lower housing, and includes a first gap on which a first hall element for detection of a magnetic field is arrangeable; a central housing that detachably engages with the lower housing, and houses the lower magnetic core along with the lower housing; an upper magnetic core that is arranged on the central housing, and forms a ring structure with the lower magnetic core for surrounding a conductor; and an upper housing that detachably engages with the central housing via an engagement portion, and houses the upper magnetic core along with the central housing, wherein the engagement portion is on the upper housing and the central housing. | ||
