Abstract

An electric connection box including an insulative board having a plurality of through holes for a plurality of terminal holders formed on the lower case of the connection box. A plurality of bus bars are pressed relative to, and are mounted fixedly in bus bar mounting grooves in the insulative board so as to assemble a bus bar circuit board. This design compensates for possible slight precision defects in press-connecting pieces of the bus bars.

Claims

1. In an electric connection box comprising a housing, a box-shaped body, a plurality of bus bars having integral upstanding tabs accommodated within said body, said tabs passing through a tab insertion hole in a wall of said body and extending into said housing outside of said body so as to form an insertion portion for an electrical connector, the improvement comprising:

bridge-like press-connecting pieces, formed respectively on a portion of said plurality of bus bars, and disposed in planes perpendicular to a circuit surface of said bus bars;

a plurality of press-connecting terminals, each having a base plate portion, tabs formed on one side of said base plate portion, and a bus bar-pressing connecting portion formed on the other side of said base plate portion and having a U-shaped slot;

terminal holders for said press-connecting terminals, said terminal holders being formed on an inner surface of said body and comprising a pair of bus bar guide walls each having a bus bar guide groove; and

an insulative board having bus bar-mounting grooves arranged in a pattern corresponding to a pattern of arrangement of said plurality of bus bars, and having through holes for said terminal holders;

said base plate portion being fixed by passing each of said tabs of said press-connecting terminal into said housing through a tab insertion hole of said terminal holder;

said electric connection box further including a bus bar circuit board, said plurality of bus bars being mounted fixedly in said bus bar-mounting grooves of said insulative board, said bus bar circuit board being placed on the inner surface of said body, so that said terminal holder is projected through said through hole; and

wherein said press-connecting piece is inserted into said guide grooves in said bus bar guide walls, and is press-fitted in and connected to said U-shaped slots of said press-connecting terminal.
