Publication number: 20140242838Abstract: To improve airtightness while reducing a usage amount of a resin for a sealing operation. A terminal block 20 of an electronic device 100 includes a resinous portion 21, a terminal member 23, and a connection member 25. Then, since a first area A1 and a second area A2 are divided by a partition wall 273 in the terminal block 20, it is possible to individually charge a charging resin 29A for blocking a through-hole A22 and a charging resin 29B for blocking a boundary portion between the terminal member 23 and the resinous portion 21. Thus, since the charging amounts of the charging resins 29A and 29B may be respectively adjusted, it is possible to appropriately charge the charging resin for improving the airtightness and to reduce the usage amount of the charging resin for a sealing operation.Type: ApplicationFiled: January 23, 2014Publication date: August 28, 2014Applicant: TDK CORPORATIONInventor: Akira IKEZAWA
