Abstract
In a drainage construction for an electrical connection box in which bus bars are accommodated and tabs projecting from the bus bars are, respectively, projected from terminal through-holes of a lower casing of the electrical connection box so as to be connected to a wiring harness, the improvement comprising: the terminal through-holes each including a main section and a drainage section; the main section having a shape substantially identical with a cross-sectional shape of each of the tabs; and the drainage section abutting on the main section so as to increase a width of each of the terminal through-holes.
Claims5
An electrical connection box comprising a drainage construction wherein bus bars are accommodated and tabs projecting from the bus bars are, respectively, projected from terminal through-holes through a bottom plate of a lower casing of the electrical connection box so as to be connected to a wiring harness, the drainage construction comprising:
- the terminal through-holes each including a main section and a drainage section;
- the main section having a shape substantially identical with a cross-sectional shape of each of the tabs;
- the drainage section abutting on the main section so as to increase a width of each of the terminal through-holes;
- and
- the bottom plate comprising a rectangular step portion at said terminal through-holes;
- wherein an upper face of said rectangular step portion is inclined toward said drainage section of said through-holes.
An electrical connection box comprising a drainage construction wherein bus bars are accommodated and tabs projecting from the bus bars are, respectively, projected from terminal through-holes of a lower casing of the electrical connection box so as to be connected to a wiring harness, the drainage construction comprising:
- the terminal through-holes each including a main section and a drainage section;
- the main section having a shape substantially identical with a cross-sectional shape of each of the tabs:
- and
- the drainage section abutting on the main section so as to increase a width of each of the terminal through-holes, said drainage section defining a gap having a cross-sectional area allowing passage of water drops therethrough;
- wherein the main section and the drainage section intersect with each other substantially orthoganally such that each of the terminal through-holes has a substantially crossed shape;
- whereby water can be positively discharged out of the lower casing through said drainage section.
