After that, it can be easily optimized, and for example, the manufacturing cost can be suppressed. Further, the electronic component holding structure 3 is a combination of each divided block 7 or the like constituting the divided block aggregate 6 according to the change of the bus bar 5 constituting the circuit even when the specifications of the applicable vehicle type are changed. It can be easily dealt with by changing and rearranging the arrangement as appropriate. In this respect as well, the electronic component holding structure 3, the electrical connection box 1, and the wire harness WH can improve versatility.

Further, since the electronic component holding structure 3, the electric connection box 1, and the wire harness WH described above have a configuration in which the bus bars 5 do not straddle the divided block aggregates 6 which are different from each other, each divided block aggregate is formed. 6 can be configured independently of other divided block aggregates 6. With this configuration, the electronic component holding structure 3, the electrical connection box 1, and the wire harness WH can be configured so that the bus bar 5 and the divided block assembly 6 can be easily assembled to each other, thus improving versatility. Therefore, the assembly workability can be improved.

Further, the electronic component holding structure 3, the electric connection box 1, and the wire harness WH described above include those in which the plurality of divided blocks 7 constituting the divided block aggregate 6 have different shapes from each other. With this configuration, the electronic component holding structure 3, the electrical connection box 1, and the wire harness WH can correspond to various variations as the divided block aggregate 6, and thus the versatility can be improved in this respect as well. can.

The electronic component holding structure, the electrical connection box, and the wire harness according to the above-described embodiment of the present invention are not limited to the above-mentioned embodiments, and various changes can be made within the scope of the claims. Is.

In the above description, the divided block aggregate 6 has four types of divided blocks 7A, divided blocks 7B, divided blocks 7C, and divided blocks 7D having different shapes as a plurality of divided blocks 7, for a total of four. However, it is not limited to this. In the divided block aggregate 6, the plurality of divided blocks 7 may all have the same shape. Further, the divided block aggregate 6 may be composed of two divided blocks 7 or may be composed of three divided blocks 7. Further, the divided block aggregate 6 may be configured to include five or more divided blocks 7.

At least one of the locking portions 72 and 74 of each of the divided blocks 7 described above is locked to the bus bar 5 so that the bus bar 5 and the divided block aggregate 6 do not fall off in the divided block assembly 6. It does not have to be all locked to the bus bar 5.
