Patent number: 10739385Abstract: A magnetic permeable member and a current detection device which can detect current in a wide range by a magnetic field detection element at low cost are provided. A magnetic permeable member includes a closed portion and an opened portion. Thus, when the large current flows through a bus bar, the magnetic field is less likely to be strong at the opened portion, thus the large current is easily detectable by a magnetic field detection element arranged at the opened portion. When the small current flows through the bus bar, the magnetic field is more likely to be strong at the closed portion, thus the small current is easily detectable by a magnetic field detection element arranged at the closed portion. Consequently, the magnetic field detection elements can be commonalized to reduce the cost, while allowing the detection of the current in a wide range.Type: GrantFiled: June 6, 2018Date of Patent: August 11, 2020Assignee: YAZAKI CORPORATIONInventors: Toshiaki Fukuhara, Makoto Sei
