Wire harness and ECU system
View Patent ↗A wire harness is provided to include: one or more electric wires; and an ECU which includes a circuit body electrically connected to one ends of the one or more electric wires and a sealing member that seals the circuit body and the one ends of the one or more electric wires. The one ends of the one or more electric wire are electrically connected to at least one of a power line pattern, a GND line pattern and a signal line pattern of the circuit body.
1. A wire harness, comprising:
one or more electric wires; and
an ECU which includes a circuit body electrically connected to one ends of the one or more electric wires and a sealing member that seals the circuit body and the one ends of the one or more electric wires,
wherein the one ends of the one or more electric wires are electrically connected to at least one of a power line pattern, a GND line pattern and a signal line pattern of the circuit body.
2. The wire harness according to claim 1 , wherein the ECU further includes a connecting part electrically connected to the one or more electric wire and sealed with the sealing member.
3. The wire harness according to claim 2 , wherein the circuit body and the connecting part are entirely sealed and coated with the sealing member, and the one or more electric wires protrude from an inside of the sealing member.
4. The wire harness according to claim 1 , wherein the ECU includes a fixing unit for fixing the ECU to a member to be fixed, the fixing unit sealed with the sealing member.
5. The wire harness according to claim 4 , wherein the fixing unit has first a part sealed with the sealing member and a second part protruded from an inside of the sealing member.
6. The wire harness according to claim 1 , wherein the ECU includes a holding unit for fixing and holding another electric wire which differs from the electric wire, the holding unit sealed with the sealing member.
7. The wire harness according to claim 6 , wherein the holding unit has a part sealed with the sealing member and a second part protruded from inside of the sealing member.
8. The wire harness according to claim 1 , wherein the circuit body is entirely sealed and coated with the sealing member, and the one or more electric wires protrude from an inside of the sealing member.
9. An ECU system comprising:
a master ECU;
a slave ECU electrically connected to the master ECU through an electric wire of a first wire harness; and
an electrical equipment electrically connected to the slave ECU through an electric wire of a second wire harness,
wherein the slave ECU includes:
a slave circuit body;
a slave sealing member that seals the slave circuit body, one end of the electric wire of the first wire harness and one end of the electric wire of the second wire harness under a state that the one end of the electric wire of the first wire harness and the one end of the electric wire of the second harness are electrically connected to at least one of a power line pattern, a GND line pattern and a signal line pattern of the slave circuit body; and
a current limiter that lowers a current supplied through the electric wire of the first wire harness from the master ECU to a prescribed current value suitable for the electrical equipment and supplies the lowered current to the electrical equipment through the electric wire of the second wire harness, and
wherein the electric wire of the first wire harness is smaller in diameter than the electric wire of the second wire harness.
10. The ECU system according to claim 9 , wherein the master ECU includes:
a master circuit body; and
a master sealing member that seals the master circuit body and the other end of the electric wire of the first wire harness under a state that the other end of the electric wire of the first wire harness is electrically connected to at least one of a power line pattern, a GND line pattern and a signal line pattern of the master circuit body.
11. The ECU system according to claim 9 , wherein the master ECU and/or the slave ECU includes integrally a holding unit that fixes and holds another electric wire which differs from the electric wires of the first and second wire harnesses.
12. The ECU system according to claim 11 , wherein the holding unit has a part formed integrally with the master ECU and/or the slave ECU.
13. The ECU system according to claim 9 , wherein the master ECU and/or the slave ECU includes integrally a fixing unit that fixes the master ECU and/or the slave ECU to a member to be fixed.
14. The ECU system according to claim 13 , wherein the fixing unit has a part formed integrally with the master ECU and/or the slave ECU.
