Electrical connection box

1. An electrical connection box comprising:

a casing;

a circuit board accommodated within the casing;

electronic component accommodating parts that are disposed on an outer face of the casing that faces a front side of the circuit board and to which electronic components are fit;

first bus bars that are erected in a vertical direction from the circuit board and configured to connect the electronic components fit to the electronic component accommodating parts and the circuit board;

second bus bars each of which includes a first vertical part erected in the vertical direction from the circuit board, a horizontal part that is bent from the first vertical part and extends in a parallel direction with respect to the circuit board, and a second vertical part that is bent from the horizontal part and extends in the vertical direction, and that connect the electronic components fit to the electronic component accommodating parts and the circuit board; and

a holding member that is disposed on the circuit board, has a press-in hole and is configured to hold the first bus bars and the second bus bars, wherein

the first bus bars are pressed into the press-in hole, and

when the electronic components are fit to the electronic component accommodating parts, the first bus bars receive an inserting force applied to the first bus bars by an inner peripheral face of the press-in hole.

2. The electrical connection box according to claim 1 , wherein

the holding member receives an inserting force applied to the horizontal parts of the second bus bars when the electronic components are inserted into the electronic component accommodating parts from the circuit board side to hold the second bus bars.

3. The electrical connection box according to claim 1 , further comprising:

second electronic component accommodating parts that are disposed on a side face of the casing disposed orthogonally to the circuit board and to which second electronic components are fit; and

third bus bars and fourth bus bars that connect the second electronic components fit to the second electronic component accommodating parts and the circuit board, wherein

the holding member holds the third bus bars and the fourth bus bars.

4. The electrical connection box according to claim 2 , further comprising:

second electronic component accommodating parts that are disposed on a side face of the casing disposed orthogonally to the circuit board and to which second electronic components are fit; and

third bus bars and fourth bus bars that connect the second electronic components fit to the second electronic component accommodating parts and the circuit board, wherein

the holding member holds the third bus bars and the fourth bus bars.

5. The electrical connection box according to claim 1 , wherein

the electronic components are fit to the electronic component accommodating parts in the vertical direction.
