Wire harness
A wire harness includes a conductive path configured to electrically connect between high-voltage devices. The conductive path includes a main line and a branch line that branches from the main line. An overcurrent cut-off portion is disposed on a way of the branch line to cut off an overcurrent.
1. A wire harness comprising:
a conductive path, configured to electrically connect between high-voltage devices, comprising:
a main line; and
a branch line that branches from the main line; and
an overcurrent cut-off portion disposed on a way of the branch line to cut off an overcurrent;
a first insulating and waterproofing portion that is provided for a branch connection portion and performs electrical insulating function and waterproof function to an exterior of the branch connection portion;
a second insulating and waterproofing portion that is provided for the overcurrent cut-off portion and performs electrical insulating function and waterproof function to the overcurrent cut-off portion;
a first electromagnetic shielding member that covers the first insulating and waterproofing portion to shield the first insulating and waterproofing portion;
a second electromagnetic shielding member that covers the second insulating and waterproofing portion to shield the second insulating and waterproofing portion; and
a protector that receives the first and second insulating and waterproofing portions respectively covered with the first and second electromagnetic shielding members,
wherein the branch connection portion is provided on an electric connection part where the branch line is electrically connected to the main line.
2. The wire harness according to claim 1 , wherein the first insulating and waterproofing portion surrounds the branch connection portion, and the second insulating and waterproofing portion surrounds the overcurrent cut-off portion.
3. The wire harness according to claim 1 , wherein the first and second electromagnetic shielding members are each formed with an opening that exposes the first and second insulating and waterproofing portions to the protector, respectively.
4. The wire harness according to claim 1 , wherein the protector comprises:
a first body portion extending in a first direction and configured to receive the first insulating and waterproofing portion such that the main line extends inside the first body portion in the first direction; and
a second body portion extending in a second direction, different from the first direction, and configured to receive the second insulating and waterproofing portion such that the branch line extends inside the second body in the second direction.
5. The wire harness according to claim 1 , wherein the second insulating and waterproofing portion comprises:
an insulating box body configured to receive the overcurrent cut-off portion through an opening of the insulating box body; and
a cover configured to cover the opening of the insulating box body.
