DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 5 are views showing one embodiment of a protector according to the present invention. In this embodiment, the above-described FIG.
The case where the present invention is applied to the wire harness W shown in FIG.
In FIG. 1, reference numeral 10 denotes a protector to be attached to a branch portion of the wire harness W. The protector 10 has a T-shaped outer shape, similarly to the protector 10 to be attached to the branch portion of the wire harness W to be routed in a two-dimensional plane. Is formed so as to define a space for receiving and guiding the wire harness W by covering the frame portion 11 with the lid portion 12. The lid portion 12 can open and close the frame portion 11 via the hinge portion 13. Are linked. The frame 11 and the lid 12 are provided with a lock claw 14a.
The closed state can be maintained by engaging with b.

This protector 10 is formed in a T-shape by connecting a plane wiring section 15 and a three-dimensional wiring section 16 in a row.
Ribs (supporting parts) on the lower surface (outer surface) of the frame 11 of the three-dimensional routing unit 16
17 is formed to extend downward.

The rib 17 is formed in a triangular shape having a hypotenuse that is more distant from the lower surface of the frame portion 11 (the wiring route of the wire harness W) as the rib 17 is more distant from the plane wiring portion 15. Tube T adjacent to the end to be formed when mounted on vehicle
It is formed so as to be longer (higher) than the outer diameter of.

For this reason, the plane wiring section 15 defines a space along the two-dimensional wiring path of the trunk section W1 drawn from the relay box R in FIG. 7, and accommodates the trunk section W1. The three-dimensional routing section 16 is supported by the ribs 17 and the trunk section W2
A space is formed along the three-dimensional wiring route of the branch line portion W2 branched from and the branch line portion W2 is accommodated.

Therefore, as shown in FIG. 2, when the wire harness W is manufactured, the protector 10
In addition, the frame 11 and the lid 12 of the three-dimensional routing section 16 can be supported by the U jig 2 in a two-dimensional plane, and the rib 17 can be positioned below the plane. The wire harness W can be held in the frame 11 by the same handling as that of the character protector. Thereafter, as shown in FIG. 3, the lid 12 is rotated through the hinge 13 so as to be engaged and locked with the frame 11, so that the branch between the trunk line W1 and the branch line W2 of the wire harness W is formed. Can be placed in a state of being accommodated.

The wire harness W is mounted on the vehicle only in accordance with the wiring route. As shown in FIG. 4, the three-dimensional wiring portion 16 of the protector 10 is supported by the rib 17 so as to be inclined. The branch line portion W2 can be gradually lifted from the trunk line portion W1 in the plane routing portion 15 and guided along a three-dimensional routing route, and can be three-dimensionally crossed over the adjacent tube T.

With this configuration, even when the wire harness W needs to be routed three-dimensionally so as not to crush the tube T, it is supported two-dimensionally by the U jig 2 at the time of manufacture. The wire harness W can be manufactured by being housed in the plane wiring section 15 and the three-dimensional wiring section 16 of the protector 10, and the wire harness W is supported by the protector 10 in which the ribs 17 incline the three-dimensional wiring section 16 at the time of mounting. The tube T
Three-dimensional crossover can be performed. Therefore,
The wire harness W can be easily prepared by arranging it in a two-dimensional plane as usual.

Further, since the protector 10 does not need to bend the three-dimensional arrangement part 16, it can be manufactured at a low cost without requiring an expensive mold.

In this embodiment, another member is provided on the support portion.
It is characterized in that a space through which it passes is formed. That is,
As shown in FIG. 5, a space S may be formed in the rib 17 of the protector 10. In this case, even when the tube T approaches the main line W1 of the wire harness W due to congestion with other members, the tube T passes through the space S of the rib 17 and the lower part of the three-dimensional routing unit 16 is The crossover can be performed through T. Specifically, for example,
As shown in FIG. 5 (a), a rib consisting only of the edge of the rib 17
27 or has a rib 37 formed by cutting the inside of the hypotenuse and the end side of the ribs 17 in the semi-circular as shown in Figure 5 (b).

In the above embodiment, the case where the three-dimensional wiring part 16 is connected to the two-dimensional wiring part 15 will be described.
The protector may include only 16 protectors, that is, the entire protector may be lifted by the support. Needless to say, the number of the ribs 17 is not limited to one, and if a protector is provided only for the three-dimensional arrangement part, it is more stable to provide two or more ribs. Needless to say, the support portion is not limited to the rib.

[0021]

According to the present invention, even a wire harness that is routed three-dimensionally can be manufactured in a two-dimensional plane and housed in a protector during manufacture.
At the time of mounting, for example, it can be three-dimensionally crossed with another member. In addition, it is also possible to collect and guide a wire harness routed in a three-dimensional routing path so as to branch from a portion routed in a two-dimensional plane and straddle another member adjacent thereto. A compact routing path may be provided through another member below the guide portion. Therefore, the wire harness can be easily manufactured by the usual operation of arranging in a two-dimensional plane.

This protector can be manufactured at low cost without specially manufacturing a special mold for defining a curved space. Also passes other members inside the support
