The invention relates to an electric Connection Box for automotive wiring or the like, and much more especially to such an electric Connection Box which prevents leakage present from creating inside a bus bar circuit when water intrudes into the electric Connection Box or when water droplets, because of condensation, deposit on the electric Connection Box.

An electric Connection Box of this common kind. Four comprises a circuit board composed of an electrically insulative base plate three along with a plurality of bus bars (circuit two mounted on the base plate three to type a laminated construction, a Connection Box physique four accommodating the circuit board, along with a lid five covering the base plate three.

Tabs extending upwardly and downwardly from the bus bars two are inserted into a fuse situation along with a relay cavity, mounted on the lid five, along with a connector mounting portion mounted on the bottom wall with the box physique four, and are linked to their mating terminals of fuses, relays, wire harness terminal connectors, and so on., if essential, via female-to-female lugterminal strips (not shown).

When such an electric Connection Box would be to be utilized, for instance, in an engine space, a waterproof cover ten is fitted on the electric Connection Box. Nevertheless, there’s a threat that in the time of washing, water beneath high pressure intrudes into the electrical Connection Box via locks 11a and 11b along with other components.
