Description

  The present invention supports a wire harness produced by bundling a large number of electric wires at a predetermined height from a wiring board, and in this state, a wire harness can be manufactured by winding a tape around the wire bundle. About.

For example, vehicles such as automobiles are provided with a large number of electrical components, and wire harnesses are used to connect these electrical components to each other. A wire harness is formed by bundling a large number of electric wires into an electric wire bundle and winding the tape around the electric wire bundle.
As shown in FIG. 8, this wire harness is manufactured so as to be routed in a vehicle using a routing jig 100.

That is, the routing support 101 is provided on the routing plate 101 of the routing jig 100, and a number of wires 104 are bundled on the U-shaped support portion 103 of the support 102 and held as a wire bundle 105. To do.
Next, the wire harness 107 that can be routed to the vehicle is manufactured by winding the tape 106 around the held wire bundle 105.

In this routing jig 100, when part 108 of the wire bundle 105 is branched from the wire bundle 105, a pair of support tools 102 are arranged adjacent to each other at a predetermined interval, and the U of the adjacent support tools 102 is arranged. A portion 108 of the wire bundle 105 is branched from between the character-shaped support portions 103.
By the way, this support tool 102 has a screw part (not shown) at the base, a nut 109 is fixed to the upper end of the screw part, and the screw part is inserted into an attachment hole (not shown) of the wiring board 101. The support tool 102 is attached to the wiring board 101 by tightening a nut (not shown) to the threaded portion protruding from the wiring board 101.
Therefore, when attaching the pair of support tools 102 close to each other, it is necessary to ensure a certain distance between the pair of support tools 102 so that the nuts 109 do not interfere with each other.

For this reason, as shown in FIG. 9, the pair of U-shaped support portions 103 are arranged at a distance L1 larger than the diameter D1 of the portion 107 of the wire bundle 105, so The bundle 105 is branched in a curved shape.
When a portion 108 of the wire bundle 105 is branched from the wire bundle 105 in a curved shape, an extra length is required as compared with a case where the portion 108 of the wire bundle 105 is branched from the wire bundle 105 at a right angle.

In order to solve this problem, a routing jig capable of branching a part 108 of the wire bundle 105 from the wire bundle 105 at a right angle has been proposed (see, for example, Patent Document 1).
