Abstract

A vehicular circuit body includes a plurality of control boxes, a trunk line that connects the plurality of control boxes to each other, and a branch line that directly or indirectly connects the control box to an accessory. The trunk line and the branch line each includes a power source line having a predetermined current capacity and a communication line having a predetermined communication capacity. Each of the plurality of control boxes includes a plurality of branch line connection portions to and from which the communication line of the branch line is attachable and detachable. Each of the plurality of branch line connection portions is provided with a lock function portion that is physically or electrically brought into a lock state in a case where the branch line is not connected thereto.

First claim

What is claimed is:

1. A vehicular circuit body provided in a vehicle, comprising:
a plurality of control boxes;
a trunk line that connects the plurality of control boxes to each other; and
a branch line that directly or indirectly connects the control box to an accessory,
wherein the trunk line and the branch line each includes a power source line having a predetermined current capacity and a communication line having a predetermined communication capacity;
wherein each of the plurality of control boxes includes a plurality of branch line connection portions to and from which the communication line of the branch line is attachable and detachable;
wherein each of the plurality of branch line connection portions is provided with a lock function portion that is physically or electrically brought into a lock state in a case where the branch line is not connected thereto;
wherein each of the plurality of branch line connection portions includes a connector to and from which an end of the communication line is attachable and detachable, and the connector having a tubular outer peripheral face that has an upper wall, a bottom wall and a pair of side walls; and
wherein the lock function portion includes:
a cover member that covers all of an opening and the tubular outer peripheral face of at least one of the plurality of connectors, and
a key part that prevents the cover member from being detached from the connectors in a lock state.

2. The vehicular circuit body according to claim 1 ,
wherein the cover member collectively covers openings and the tubular outer peripheral face of the plurality of connectors.
