  • Publication number: 20050099778
    Abstract: An insulation adhesive is applied to an bonding surface of a heat radiation member to positively ensure a thickness of an insulation layer when bonding a circuit section and a heat radiation member through the insulation layer. An insulation sheet-like element provided with numerous flow paths is superposed on the insulation adhesive to seep the insulation adhesive through the flow paths before the insulation adhesive is solidified. A circuit section is stacked further on the insulation sheet-like element. The insulation adhesive bonds the circuit section and heat radiation member to each other.

  • Publication number: 20020061682
    Abstract: 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.
