Abstract

An electrical junction box has fuse attachment portions arranged side by side and open to a lateral side of a box body. Recesses ( 88 ) are formed at opposite side edges of an L-shaped bend ( 78 ) of each of connecting terminals ( 48 a - 48 c ), and in a terminal support block ( 42 ) in which a plurality of terminal insertion holes ( 54 a ) to ( 54 c ) are formed and support pins ( 74 ) that lock the connecting terminals ( 48 a ) to ( 48 c ) are inserted, temporal retaining portions ( 68 ) are formed in respective opening ends ( 70 ) of the terminal insertion holes ( 54 a - 54 c ) on a terminal insertion side, the temporal retaining portions ( 68 ) temporarily positioning the connecting terminals ( 48 a ) to ( 48 c ) within the respective terminal insertion holes ( 54 a - 54 c ) by the recesses ( 88 ) of the connecting terminals ( 48 a ) to ( 48 c ) being fit into the temporal retaining portions ( 68 ).

First claim

What is claimed is:

1. An electrical junction box, comprising:
a fuse case formed with a plurality of fuse attachment portions arranged side by side and open to a lateral side of the fuse case;
a terminal support block adjacent the fuse case, a plurality of terminal insertion holes formed side by side in the terminal support block;
a plurality of connecting terminals mounted in the respective terminal insertion holes and in proximity to the fuse attachment portions, each of connecting terminals having an L-shaped bend, recesses formed at opposite side edges of each of the connecting terminals and extending on both sides of the bend in a length direction of the connecting terminals;
support pins inserted into the terminal support block and locking the connecting terminals; and
temporal retaining portions formed at opening ends of the terminal insertion holes of the terminal support block, the recesses of the connecting terminal being fit to the temporal retaining portions for temporarily positioning the connecting terminals within the terminal insertion holes.

2. The electrical junction box of claim 1 , wherein an inner surface of the bend of each of the connecting terminals is locked by the terminal support block.

3. The electrical junction box of claim 1 , a rear end face of each of the connecting terminals is flush with an opening end face of the terminal insertion holes when the connecting terminals are inserted properly into the respective terminal insertion holes of the terminal support block.

4. The electrical junction box of claim 1 , wherein the connecting terminals are formed with locking notches, the support pins engaging the locking notches.

5. The electrical junction box of claim 1 , wherein the locking notches extend in directions perpendicular to extending directions of the connecting terminals.

6. The electrical junction box of claim 1 , wherein the connecting terminals have connecting portions that protrude forward from the terminal support block and into the fuse accommodating portions.

7. The electrical junction box of claim 1 , wherein the connecting terminals are disposed in a plurality of tiers in the terminal support block.
