Current detecting device with a core having an integrally fixed engaging member

摘要

A shield member is placed in a case, and connector pins extend through respective through capacitors and are soldered to the shield member. A core is inserted in the case, and has an engaging member engaging an upstanding portion of the case, the core having a gap fitted over a ridge on the case. A printed-circuit board has positioning holes fitted over pins on the core. The connector pins have respective upper ends inserted through and soldered to through holes defined in the printed-circuit board. Attachment holes defined in the printed-circuit board are held in registry with threaded holes defined in an upper end of the upstanding portion of the case, and the printed-circuit board is fastened to the upstanding portion by screws threaded through the attachment holes into the threaded holes. A shield cover is bent over into alignment with an upper edge of the shield member, and teeth on the shield member are bent inwardly onto and soldered or spot-welded to the shield cover. A cover is finally fixed to the case by fitting teeth on the cover into recesses in an upper end of the cover.
