Publication number: 20020061682Abstract: A fuse main body made of a conductor in which connection terminals are provided at the opposite ends of a fusing portion is covered by an insulating covering member except part of the two connection terminals. The connection terminals are electrically connected with the fuse by being inserted into forked inserting portions of press-contact blades. The covering member is formed with slit-shaped notches which are shaped such that leading ends of the press-contact blades are insertable and adapted to partly expose the connection terminals. The height of the fuse can be shortened, which in turn contributes to a substantially smaller electrical connection box in which the fuse is to be mounted.Type: ApplicationFiled: November 19, 2001Publication date: May 23, 2002Applicant: AUTONETWORKS TECHNOLOGIES, LTD.Inventors: Ryuji Nakanishi, Shigeki Yamane, Takahiro Onizuka, Isao Isshiki
