  Conventionally, as a means for grounding a ground wire included in a wire harness routed in an automobile or the like, a ground terminal is fixed to a terminal of the ground wire, and the ground terminal is fixed to a predetermined ground portion such as a body with a bolt. That is done.

For example, in Patent Document 1 below, a ring-shaped ground terminal is fixed to the end of a ground wire, and a bolt is inserted into the center hole of the ground terminal and tightened to a screw hole on the body side, whereby the ground terminal is attached to the body.

JP 2002-231334 A (FIGS. 2 and 3)

  In the wiring structure as described above, if the wire harness moves relatively relative to the grounding location where the grounding terminal is fixed due to vehicle vibration or the like, a large strength load is applied to the grounding terminal or the grounding wire, disconnection or the like. May be incurred. Therefore, it is desirable to securely fix the wire harness to the vehicle side particularly in the vicinity of the ground terminal.

  As a means for fixing the wire harness to the vehicle side in this way, an appropriate portion of the wire harness is wrapped around an appropriate position of the vehicle with an adhesive tape, or an appropriate portion of the wire harness is held by a clamp member dedicated to fixing the wire harness. It is generally known that the clamp member is engaged with an appropriate position of the vehicle, but in any case, an operation completely different from the operation of fixing the ground terminal to the body is performed in a narrow space in the vehicle. This process is very troublesome.

  In view of such circumstances, an object of the present invention is to provide a technique capable of efficiently grounding an earth wire included in a wire harness and fixing the wire harness with a simple operation.

  As means for solving the above-mentioned problems, the present invention is a method of electrically connecting a ground wire included in a wire harness to a ground portion of a vehicle and fixing the ground wire to the ground portion, A step of connecting the ground wire to the connection conductor of a ground connector having a connection conductor for connecting to the ground portion and an insulation housing for holding the connection conductor; and the insulation housing of the connector on the outer peripheral surface of the body of the wire harness. And a step of fixing the connection conductor of the earth connector fixed to the wire harness main body to the grounding portion in a state of being in contact with the grounding portion.

  The present invention also includes a vehicle wire harness that includes a ground wire, the ground wire is electrically connected to a ground portion of the vehicle, and is fixed to the ground portion, the ground wire and the ground portion. And a ground connector having an insulating housing for holding the connection conductor, the insulating housing of the ground connector is fixed on the outer peripheral surface of the body of the wire harness, and the connection conductor of the connector An earth connection portion is provided that is fixed to the ground portion in contact with the ground portion.

  According to these configurations, by connecting the ground wire included in the wire harness and the connection conductor of the ground connector and fixing the ground connector on the outer peripheral surface of the main body of the wire harness, By simply fixing the ground connection portion of the ground connector to the ground portion of the vehicle, the ground wire is electrically connected to the ground portion through the connection conductor and at the same time the body of the wire harness is grounded. It can be fixed to the grounding part via a connector. That is, by fixing the insulating housing of the ground connector on the outer peripheral surface of the body of the wire harness, the ground connector is electrically connected to the ground wire and the electrical connection medium interposed between the ground wire and the wire harness body. And a wire harness fixing tool interposed between the grounding portion and the grounding portion, whereby both grounding and fixing of the wire harness can be performed with a simple operation.

  Specifically, as an aspect of fixing the insulating housing of the ground connector on the outer peripheral surface of the main body of the wire harness, the insulating conductor of the ground connector is connected to the ground wire of the wire harness. A wire harness fixing portion that contacts the outer peripheral surface of the main body of the wire harness is formed, and a tape is wound around the wire harness fixing portion and the outer peripheral surface of the main body of the wire harness so that the wire harness fixing portion becomes the wire harness. What is fixed to the main body is suitable.

  In this way, the tape can be wound around the insulating housing in such a manner that the connecting conductor is in contact with the outer peripheral surface of the main body of the wire harness while being connected to the ground wire of the wire harness. By using the ground connector in which the shaped wire harness fixing portion is formed, the insulating housing can be easily and reliably fixed on the outer peripheral surface of the main body of the wire harness by so-called tape winding.

  More specifically, it is preferable that the wire harness fixing portion has a shape that projects outward from both sides of a portion where the connection conductor and the ground wire are connected.

  According to this configuration, by winding the tape across both wire harness fixing portions formed on the insulating housing and the outer peripheral surface of the main body of the wire harness, the insulating housing remains connected to the ground wire and the connection conductor. Can be fixed to the wire harness body in a stable state.

  In the present invention, the specific structure of the ground connector is not limited. For example, the connection conductor includes an earth connection conductor having the earth connection portion and an electric wire connection conductor to which the electric wire side terminal is connected, and a capacitor is interposed between the earth connection conductor and the electric wire connection conductor. If a connector with a built-in capacitor, that is, a connector with a built-in capacitor is used as the ground connector, noise can be reduced by connecting the ground wire to the ground through a capacitor.

  As described above, according to the present invention, there is an effect that the ground wire included in the wire harness can be grounded and the wire harness can be fixed efficiently with a simple operation.
