## Abstract

A circuit body for a vehicle includes: a plurality of control boxes capable of controlling input and output of at least one of electric power and a communication signal; a trunk line harness connecting one of the plurality of control boxes and another of the plurality of control boxes; and a branch line harness connecting the control box and the electrical component. The control box includes: a trunk line connecting portion to which the trunk line harness is connected; and a branch line connecting portion to which the branch line harness is connected. At least one of the trunk line connecting portion and the branch line connecting portion includes a plurality of connectors which are classified into a plurality of groups according to an allowable current amount and in which a plurality of the connectors classified into the same group have connection compatibility.

## Claims

### Claim 1

A circuit body for a vehicle which is wired on a vehicle body of the vehicle for performing supply of electric power to an electrical component and communication of various communication signals with the electrical component, the circuit body comprising:
a plurality of control boxes separately disposed on the circuit body and capable of controlling input and output of at least one of the electric power and the communication signal;
a trunk line harness connecting one of the plurality of control boxes and another of the plurality of control boxes; and
a branch line harness connecting the control box and the electrical component,
wherein each of the plurality of control boxes comprises:
a trunk line connecting portion to which the trunk line harness is connected; and
a branch line connecting portion to which the branch line harness is connected, and
wherein at least one of the trunk line connecting portion and the branch line connecting portion comprises a plurality of connectors which are classified into a plurality of groups according to an allowable current amount and in which a plurality of the connectors classified into the same group have connection compatibility.
