Description

  The present invention relates to a wire harness fixture for fixing a wire harness to a member to be attached.

  In a vehicle such as an automobile, the wire harness is fixed to a member to be attached such as a panel or a bumper and is routed in various parts of the vehicle. As a conventional wire harness fixture for fixing the wire harness to these members to be attached, one shown in FIG. 8 is known (for example, see Patent Document 1).

  As shown in FIG. 8, the wire harness 100 is fixed to a bumper 103 that is a member to be attached by a harness holding member 101 and a rib clip member 102 that are attachments. A rib 104 is projected from the bumper 103, and the synthetic resin harness holding member 101 holding the wire harness 100 is attached to the rib 104 by inserting the rib 104 through the insertion hole 105.

  The rib clip member 102 is formed such that the metal plate is folded in half so that the rib 104 can be sandwiched between the opposing pieces 106 and 107, and the rib clip member 102 is attached to the tip of the rib 104. At least one of the piece portions 106 and 107 of the rib clip member 102 is a presser that extends toward the tip end side of the rib 104 and is raised inward when the rib clip member 102 is attached to the tip end portion of the rib 104. A piece 108 is formed, and an edge portion of the holding piece 108 bites into the rib 104 to prevent the rib clip member 102 from coming off from the rib 104.

  At least one end of each of the pieces 106 and 107 of the rib clip member 102 is formed with a retaining piece 109 that extends toward the base end of the rib 104 and is raised outward. The retaining piece 109 is in contact with the harness holding member 101 attached to the rib 104 to prevent the harness holding member 101 from coming off the rib 104.

JP 2004-357456 A

  However, in the conventional wire harness fixture disclosed in Patent Document 1, the holding piece 108 is not supported at all on the surface opposite to the contact surface with the rib 104, so The edge portion is bitten into the rib 104 only by the rigidity, that is, the rigidity of the metal plate forming the rib clip member 102. For this reason, the edge of the presser piece 108 is not sufficiently bitten into the rib 104, and the rib clip member 102 and the harness holding member 101 may fall off the rib 104. The fixing strength is not sufficient.

  In order to cope with this, when a high-rigidity metal plate is used as the metal plate forming the rib clip member 102, the mounting workability when the rib clip member 102 is attached to the rib 104, and the rib clip member 102 are used. In addition, there is a risk that dismantling workability when the harness holding member 101 is removed from the rib 104 is lowered.

  In the conventional wire harness fixture disclosed in Patent Document 1, the rib clip member 102 is first attached to the rib 104, and then the rib 104 and the rib clip member 102 are both inserted into the insertion hole 105. The harness holding member 101 is attached to the rib 104. That is, in order to fix the wire harness 100 to the bumper 103, two steps of attachment of the rib clip member 102 and attachment of the harness holding member 101 are required, resulting in poor work efficiency.

  Further, in the conventional wire harness fixture disclosed in Patent Document 1, the rib clip member 102 is made of a metal plate with respect to the synthetic resin harness holding member 101, and the harness holding member 101 after disassembly for recycling. And the rib clip member 102 need to be separated, and therefore the recyclability is poor.

  The present invention has been made in view of the above-described circumstances, and a purpose thereof is a wire harness that is excellent in workability and recyclability for attachment to a member to be attached, and can further enhance the fixing strength to the member to be attached.
