摘要:
PROBLEM TO BE SOLVED: To provide a magnetic treatment device in which a magnetic through-hole which one end of the iron core of a coil enters is covered by a cover sheet with a substantially flat rear face and, the one end of the iron core is allowed to come close to the cover sheet, to thereby make "improvement of the magnetic efficiency" compatible with "maintaining of case strength" and to further achieve "improvement of manufacturing efficiency."SOLUTION: A magnetic treatment device comprises: a case body 2 carrying a magnetic action surface 2a and a cylindrical coil 3 contained in the case body 2. One end part 7a of the iron core 7 protrudes from one end side 4a of the coil 3. The one end part 7a of the iron core 7 enters a magnetic through-hole 8 from its inner surface opening 8b, the magnetic through-hole 8 passing through the magnetic action surface 2a side of the case body 2 in a thickness direction. A substantially flat cover sheet 16 of a rear face 16a on the case body 2 side covers an outer surface opening 8c of the magnetic through-hole 8, and the tip of the one end part 7a of the iron core 7 comes close to the cover sheet 16.COPYRIGHT: (C)2015,JPO&INPIT【課題】コイルの鉄心一端が進入する貫磁孔を裏面が略平坦な被覆シートで被い、被覆シートに鉄心一端を近接させることで、「磁気効率の向上」と「ケース強度保持」を両立しつつ、更に「製造の効率化」を図る。【解決手段】磁気作用面2aが設けられたケース体2とケース体2に内蔵された筒状のコイル3を有し、コイル3の一方端4aから鉄心7の一端部7aが突出し、鉄心7の一端部7aがケース体3の磁気作用面2a側を厚み方向に貫通した貫磁孔8へ内面開口8bから進入し、貫磁孔8の外面開口8cをケース体2側の裏面16aが略平坦な被覆シート16で被い、被覆シート16に鉄心7の一端部7aの先端が近接している。【選択図】図1
