Electrical junction box
View Patent ↗An object of the present invention is to provide an electrical junction box allowing a hollow cavity portion and a component receiving portion to be easily distinguished from each other so that the workability upon inserting components is improved. The electrical junction box includes a cassette block. Electronic components such as relay or fuse are mounted on an upper surface of the cassette block, and a bus bar and a terminal are inserted into a lower surface of the cassette block. The lower surface of the cassette block is provided with a bus bar receiving portion into which the bus bar is inserted, a terminal receiving portion into which the terminal is inserted, and a plurality of hollow cavity portions adjacent to the bus bar receiving portion and the terminal receiving portion and into which no component is inserted.
1. An electrical junction box comprising a frame,
wherein an electronic component is mounted on an upper surface of the frame, and a bus bar or a terminal is inserted into a lower surface of the frame,
wherein the lower surface of the frame is provided with a component receiving portion into which the bus bar or the terminal is inserted and a plurality of hollow cavity portions into which no component is inserted, and wherein a lower end of at least one of the plurality of hollow cavity portions is situated 1 to 5 mm nearer the upper surface than a lower end of the component receiving portion.
