Bus bar edge structure of electric junction box
View Patent ↗A bus bar edge structure of an electric junction box having a junction block main body, a bus bar-receiving gap arranged on the junction block main body, and a space communicating with the bus bar-receiving gap and arranged in a thickness direction of the bus bar includes a projection piece projecting from an edge of the bus bar at an opening side of the space in the thickness direction of the bus bar. An electric wire led from the junction block main body is guided to the projection piece so as to prevent interference with the edge of the bus bar. The projection piece functions as a press-operating portion configured to insert the bus bar into the bus bar-receiving gap. The projection piece is positioned in an opening of a longitudinal groove arranged in the space so as to prevent the electric wire from entering into the opening.
1. A bus bar edge structure of an electric junction box having a junction block main body, a bus bar-receiving gap arranged on the junction block main body, and a space communicating with the bus bar-receiving gap and arranged in a thickness direction of the bus bar, the bus bar edge structure comprising:
a projection piece projecting from an edge of the bus bar at an opening side of the space in the thickness direction of the bus bar,
wherein an electric wire led from the junction block main body is guided to the projection piece so as to prevent interference with the edge of the bus bar.
2. The bus bar edge structure of the electric junction box according to claim 1 , wherein the projection piece functions as a press-operating portion configured to insert the bus bar into the bus bar-receiving gap.
3. The bus bar edge structure of the electric junction box according to claim 1 , wherein the space includes a longitudinal groove in which a nut is attached and a working space in which a bolt is fastened, and the projection piece is positioned in an opening of the longitudinal groove so as to prevent the electric wire from entering into the opening.
4. The bus bar edge structure of the electric junction box according to claim 3 , wherein a pair of partition ribs is formed in the longitudinal groove and extends to the opening of the longitudinal groove, and the projection piece is closely arranged between the pair of the partition ribs.
5. The bus bar edge structure of the electric junction box according to claim 1 , wherein the projection piece is arranged in one side of the bus bar in the longitudinal direction, a U-shaped folded connection is arranged in the other side of the bus bar in the longitudinal direction, and the projection piece and the folded connection function as a press-operating portion configured to insert the bus bar into the bus bar-receiving gap.
