Abstract

A circuit wiring body includes a wiring main body and an electrical connection unit. The wiring main body includes a conductive member that is wired between a cylinder head and a head cover in an engine, and an insulating member that stores therein the conductive member. The electrical connection unit includes a terminal that electrically connects a counterpart connector of an electrical component (electromagnetic driving valve) at least interposed between the cylinder head and the head cover to the conductive member.

First claim

What is claimed is:

1. A circuit wiring body comprising:
a wiring main body including:
a collective connector including a casing and at least one terminal;
a connecting unit electrically connected to and extending from the collective connector;
a first wiring unit electrically connected to and extending from the connecting unit;
a second wiring unit electrically connected to and extending from the connecting unit;
at least one conductive member in each of the connecting unit, the first wiring unit and the second wiring unit that is located between a cylinder head and a head cover in an engine

at least one electrical connector on each of the first wiring unit and the second wiring unit, each electrical connector including a casing and a terminal that electrically connects a counterpart connector of an electrical component at least interposed between the cylinder head and the head cover to the conductive member; and
an insulating member that integrally forms the casing of the collective connector and the casing of the at least one electrical connector on each of the first wiring unit and the second wiring unit, and stores therein each conductive member of the connecting unit, the first wiring unit, and the second wiring unit.

2. The circuit wiring body according to claim 1 , wherein
the electrical component is provided for each cylinder of the engine.

3. The circuit wiring body according to claim 1 , wherein
the connector unit, the first wiring unit, and the second wring unit collectively form a U-shape.

4. The circuit wiring body according to claim 1 , wherein
the electrical component is connected to the cylinder head along an insertion direction,
the terminal of the at least one connector on each of the first wiring unit and the second wiring unit extends in the insertion direction, and
the at least one connector on each of the first wiring unit and the second wiring unit includes an aperture on a side reverse to an insertion direction side of the electrical component.

5. The circuit wiring body according to claim 1 , wherein
the wiring main body is wired along an outer wall surface of the cylinder head.

6. The circuit wiring body according to claim 5 , wherein
the electrical component is provided for each cylinder of the engine.

7. The circuit wiring body according to claim 5 , wherein
the wiring main body is fitted into a fitting unit provided on the cylinder head.

8. The circuit wiring body according to claim 7 , further comprising:
a fixing member that grounds the conductive member to be grounded through the cylinder head and fixes the wiring main body to the cylinder head.

9. The circuit wiring body according to claim 7 , wherein
the electrical component is provided for each cylinder of the engine.

10. The circuit wiring body according to claim 5 , further comprising:
a fixing member that grounds the conductive member to be grounded through the cylinder head and fixes the wiring main body to the cylinder head.

11. The circuit wiring body according to claim 10 , wherein
the electrical component is provided for each cylinder of the engine.

12. The circuit wiring body according to claim 1 , wherein
the wiring main body further including:
a third wiring unit electrically connected to and extending from the connecting unit,
at least one connector on the third wiring unit, the at least one connector on the third wiring unit including a casing and a terminal, and
at least one conductive member in the third wiring unit, and

the insulating member integrally forms the casing of the at least one connector of the third wiring unit, and stores therein the at least one conducive member of the third wiring unit.

13. The circuit wiring body according to claim 12 , wherein
the connector unit, the first wiring unit, and the second wiring unit collectively form a U-shape, and
the third wiring unit is located between the first wiring unit and the second wiring unit.

14. The circuit wiring body according to claim 12 , wherein
a second electrical component is connected to the cylinder head along a second insertion direction,
the terminal of the at least one connector on the third wiring unit extends in the second insertion direction, and
the at least one connector on the third wiring unit includes an aperture on a side reverse to an insertion direction side of the second electrical component.
