Electrical junction box
View Patent ↗Disclosed is an electrical junction box including a case, and a block housed in the case. The case includes a frame, and a lower cover attached to a lower end side of the frame a joint part part of an outer wall of the frame and an outer wall of the cover an upper end of the outer wall of the lower cover is positioned more inwardly than a lower end of the outer wall of the frame and nearly the same height as a component insertion plane. At an edge portion of the block is disposed a waterproof barrier located between the component housing of the block and the joint part part and extending below the component insertion plane of a lower end of the component housing.
1. An electrical junction box comprising:
a case including a frame, and a cover attached to a lower end side of the frame;
a separate block, housed in the case, the block including a plurality of component housings for components;
a joint part of an outer wall of the frame and an outer wall of the cover where the outer wall of the frame and the outer wall of the cover contact in an attached state; and
a waterproof barrier disposed at an outer edge of the block and between a component housing and the joint part, extending below a component insertion plane of a lower end of the component housing with the waterproof barrier in contact with neither the frame nor the cover, and having an exposed surface below the component insertion plane in facing relation with the joint part,
wherein a vertical tip of the outer wall of the frame is formed into an L-shape or an inverse L-shape, and a vertical tip of the outer wall of the cover is formed into a shape complementary to the shape of the vertical tip of the outer wall of the frame, the joint part is formed such that the vertical tips of the outer wall of the frame and the outer wall of the cover are vertically jointed in halving joint form with each other.
2. The electrical junction box as claimed in claim 1 , wherein the frame and the cover meet in the attached state, is located at the same height or above as the component insertion plane.
3. An electrical junction box comprising:
a case including a frame, and a cover attached to a lower end side of the frame;
a separate block, housed in the case, the block including a plurality of component housings for components;
a joint part of an outer wall of the frame and an outer wall of the cover where the outer wall of the frame and the outer wall of the cover contact in an attached state; and
a waterproof barrier disposed at an outer edge of the block and between a component housing and the joint part, extending below a component insertion plane of a lower end of the component housing with the waterproof barrier in contact with neither the frame nor the cover, and having an exposed surface below the component insertion plane and exposed to an outside of the block,
wherein a vertical tip of the outer wall of the frame is formed into an L-shape or an inverse L-shape, and a vertical tip of the outer wall of the cover is formed into a shape complementary to the shape of the vertical tip of the outer wall of the frame, the joint part is formed such that the vertical tips of the outer wall of the frame and the outer wall of the cover are vertically jointed in halving joint form with each other.
