BACKGROUND

The present disclosure relates to a wire harness including an electric wire that includes a core wire, an insulating inner cover that covers an outer circumference of the core wire, and a conductive shield member that covers an outer circumference of the insulating inner cover.

Some wire harnesses for vehicles include, for example, an electric wire that includes a core wire, an insulating inner cover that covers an outer circumference of the core wire, a conductive shield member that covers an outer circumference of the insulating inner cover, and an insulating outer cover that covers an outer circumference of the shield member. In addition, a structure in which a shield member is grounded has been proposed (see JP 2005-285748A, for example).

In the wire harness described in JP 2005-285748A, an end portion of the shield member is exposed from an end portion of the insulating outer cover, and the exposed portion is folded back to an outer circumferential side of the insulating outer cover.

A tubular member (shield sleeve) is provided between the outer circumferential surface of the end portion of the insulating outer cover and the folded-back portion of the shield member.

The folded-back portion of the shield member is fitted into a conductive tubular body (shield contact). The tubular body is inserted into an insertion hole of a plate-shaped ground member and attached to the ground member, and the ground member is attached to an attached body.

SUMMARY

In the wire harness described in JP 2005-285748A, the insertion hole of the ground member and the tubular body are separate bodies.

Also, in order to suppress deformation of the core wire when the folded-back portion of the shield member is fitted into the tubular body, a tubular member is provided between the insulating outer cover and the folded-back portion of the shield member.

Accordingly, the number of components for connecting the shield member to the ground increases, and the assembling operation becomes complicated.

An exemplary aspect of the disclosure provides a wire harness in which a shield member can be grounded with a simple configuration.

A wire harness according to an exemplary aspect includes an electric wire that includes a core wire, an insulating inner cover that covers an outer circumference of the core wire, and a conductive shield that covers an outer circumference of the insulating inner cover, and the wire harness includes: a conductive bracket that includes a plate including an insertion hole through which the electric wire is inserted and a protrusion protruding from an edge of the insertion hole in the plate; and a fastener that fastens a folded-back portion of the shield that is folded back to an outer circumferential side of the protrusion to the protrusion.

With this configuration, the shield of the electric wire is electrically connected to the bracket by folding back the portion of the shield of the electric wire protruding from the end of the protrusion of the plate to the outer circumferential side of the protrusion, and fastening the folded-back portion to the protrusion with the fastener. By attaching the bracket to a conductive attachment object, the shield can be grounded.

Here, because the protrusion is interposed between the fastener and the electric wire, deformation of the electric wire due to fastening by the fastener is suppressed.

Therefore, the shield can be grounded with a simple configuration.

In the above wire harness, it is preferable that the bracket includes a plurality of the insertion holes and a plurality of the protrusions respectively protruding from edges of the insertion holes.

With this configuration, the shields of the plurality of electric wires can be grounded by one bracket. Therefore, the number of components required for grounding the shield can be reduced.

In the above wire harness, it is preferable that the protrusion has a tubular shape.

With this configuration, because the protrusion is interposed between the fastener and the electric wire over the entire circumference, it is possible to further suppress deformation of the electric wire due to fastening by the fastener.

In the above wire harness, it is preferable that the wire harness further includes a body made of resin that sandwiches the plate in a thickness direction, wherein the plate of the bracket includes a flange protruding radially outward from an entire circumference of the body, and the body and the bracket form an attachment to be attached to a device to which the wire harness is to be attached.

With this configuration, the body and the bracket form the attachment to be attached to a device to which the wire harness is to be attached.

Here, because the bracket is sandwiched by the body in the thickness direction, it is possible to prevent moisture or the like from entering from the outside to the inside of the housing of the device to which the attachment is to be attached through the insertion hole.

In the above wire harness, it is preferable that an annular groove is provided on an outer circumferential surface of the body, and an annular seal is fitted into the annular groove.

With this configuration, when the body of the attachment is inserted and attached to the attachment port of the housing of the device, the seal fitted into the annular groove of the body comes into intimate contact with the inner circumferential surface of the attachment port.

As a result, it is possible to prevent moisture or the like from entering the housing through a gap between the attachment port and the body.

According to the present disclosure, the shield can be grounded with a simple configuration.
