Electric junction box
View Patent ↗Disclosed is an electric junction box in which a pair of cassette blocks is arranged at intervals to each other in a component-attaching direction, capable of downsizing without increase of the number of component. The electric junction box comprises a pair of cassette blocks, configured to attach electric components thereto, arranged at intervals mutually in a component-attaching direction; and a cross-sectionally U-shaped bus bar attached to one cassette block, electrically connected to the electric components, a middle of the bus bar being arranged in a direction perpendicular to the component-attaching direction, both ends of the U-shaped bus bar being arranged in the component-attaching direction, wherein the electric components attached to the other cassette block are opposed to the middle of the bus bar.
1. An electric junction box, comprising:
a pair of cassette blocks configured to attach electric components thereto, arranged at intervals to each other in a component-attaching direction; and
a cross-sectionally U-shaped bus bar attached to one of the pair of cassette blocks, electrically connected to the electric components, and including a middle portion and both ends, wherein the middle portion of the bus bar is arranged in a direction perpendicular to the component-attaching direction, and both ends of the bus bar are arranged in the component-attaching direction, and
wherein the electric components attached to the other of the pair of cassette blocks are opposed to the middle of the bus bar.
2. The electric junction box as claimed in claim 1 , wherein the electric components connected to the bus bar in the one of the pair of cassette blocks are arranged in two lines.
3. The electric junction box as claimed in claim 2 , further comprising a plate disposed in the one or the other of the pair of cassette blocks, wherein the plate extends toward the other or the one of the pair of cassette blocks, and is provided with an engaging part for being engaged by the other or the one of the pair of cassette blocks.
4. The electric junction box as claimed in claim 3 , wherein the one of the pair of cassette blocks is configured to attach a fuse thereto, wherein the other of the pair of cassette blocks is configured to attach a relay thereto, and wherein the relay is connected in series to the fuse.
5. The electric junction box as claimed in claim 2 , wherein the one of the pair of cassette blocks is configured to attach a fuse thereto, wherein the other of the pair of cassette blocks is configured to attach a relay thereto, and wherein the relay is connected in series to the fuse.
6. The electric junction box as claimed in claim 1 , further comprising a plate disposed in the one or the other of the pair of cassette blocks, wherein the plate extends toward the other or the one of the pair of cassette blocks, and is provided with an engaging part for being engaged by the other or the one of the pair of cassette blocks.
7. The electric junction box as claimed in claim 6 , wherein the one of the pair of cassette blocks is configured to attach a fuse thereto, wherein the other of the pair of cassette blocks is configured to attach a relay thereto, and wherein the relay is connected in series to the fuse.
8. The electric junction box as claimed in claim 1 , wherein the one of the pair of cassette blocks is configured to attach a fuse thereto, wherein the other of the pair of cassette blocks is configured to attach a relay thereto, and wherein the relay is connected in series to the fuse.
