Abstract

The purpose of the present invention is to provide a holding fixture of a wire harness branch part so that a wiring operation including tape wrapping can be easily performed, the wired state can be hold until a vehicle loading stage, and space efficiency can be improved. A holding fixture of a wire harness branch part, in which branch wires (W2) of a wire harness are branched in a direction which intersects trunk wires (W1) of the wire harness from the trunk wires, includes a trunk wire guiding part (12) which guides the trunk wires, and special wire branching and guiding parts (13) which make special wires (Wt), which are those wires among the branch wires whose minimum bending radius is restricted, to be curved in a direction which intersects the trunk wires, and guide the special wires. The special wire branching and guiding parts (13) are formed by arc-shaped board walls which make the special wires to be curved with a predetermined radius of curvature and guide the special wires.

Description

technical field [0001] The present invention relates to a holding device for a branched portion of a wire harness in which a branch wire is branched from a trunk line in a direction intersecting with a trunk line of a wire harness, and in particular, A holding device for a branch of a wire harness when special wires (coaxial cables, optical cables, tubes, stranded wires, steel cables, etc.) are accommodated in a branch wire. Background technique [0002] When a branch wire is pulled out from a trunk wire of a wire harness, generally, electric wires accommodated in the trunk wire (electric wires to be branched) are bent in a direction intersecting the trunk wire (for example, a direction perpendicular to the trunk wire) and pulled out. When manufacturing such a T-shaped wire harness branch portion, typically, wiring is performed by using a wiring board and a wiring jig (for example, see Patent Document 1). [0003] Figure 10 is a top view showing a wiring T-shaped harness b...
