Circuit body for vehicle
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.
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 arranged into a plurality of groups according to an allowable current amount, and each of the groups has a respective connector size that is different from the connector size of each other of the groups, and the size of each connector of each of the groups is the same such that the connectors arranged into the same group have connection compatibility and are all located in a same area of the at least one of the trunk line connecting portion and the branch line connecting portion spaced away from the connectors arranged into other of the groups,
wherein the plurality of groups comprises a first group for a first allowable current amount and a second group for a second allowable current amount, the first allowable current amount being larger than the second allowable current amount,
wherein an interval at which the connectors of the first group are arranged is smaller than a minimum distance between the first group and the second group, and
wherein an interval at which the connectors of the second group are arranged is smaller than the minimum distance between the first group and the second group.
