Electrical junction box
View Patent ↗An electrical junction box includes: a frame; and a block having a double wall defined by outer and inner walls. At a position where the double wall and a component receiving section of the block are opposite to each other, a lower end of the inner wall is positioned higher than a component insertion surface at a lower end of the component receiving section, and a waterproof wall is provided on the lower end and an outer edge at the double wall side of the component receiving section. The waterproof wall is defined by a first waterproof portion extended horizontally toward the outer wall from the lower end and the outer edge at the double wall side of the component receiving section, and a second waterproof wall extended downward and parallel to the outer wall from an end at the outer wall side of the first waterproof wall.
1. An electrical junction box comprising:
a frame having a double wall defined by an outer wall and an inner wall disposed with a gap between the inner wall and the outer wall; and
a block received in the frame and having at least one component receiving section,
wherein at a position where the double wall and the at least one component receiving section are opposite to each other, a lower end of the inner wall is extended to at least an upper end of the opposite component receiving section and positioned higher than a component insertion surface at a lower end of the component receiving section, and
wherein a waterproof wall extended toward the outer wall or extended lower than the component insertion surface is provided on the lower end and an outer edge at the double wall side of the opposite component receiving section.
2. The electrical junction box as claimed in claim 1 ,
wherein the waterproof wall is defined by a first waterproof wall extended toward the outer wall from the lower end of the opposite component receiving section and from the outer edge of the opposite component receiving section at the double wall side, and a second waterproof wall extended downward and parallel to the outer wall from an end of the first waterproof wall at the outer wall side.
3. The electrical junction box as claimed in claim 1 ,
wherein the opposite component receiving section is partially extended lower than the component insertion surface, and
wherein the waterproof wall is defined by a portion lower than the component insertion surface.
