BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective device for a wire harness, and more particularly, an external interference member that can be easily mounted and inexpensively configured with a simple configuration regardless of the diameter of the wire harness and the form of the wire harness that are routed along the vehicle body. The wire harness is protected from the above.
[0002]
[Prior art]
As shown in FIG. 8, the wire harness W / H routed inside the automobile has a cylindrical corrugated tube 2 that repeats annular irregularities in the longitudinal direction at the required position, and the wire harness W / H In many cases, it is prevented from being damaged by interference with other members.
[0003]
In the portion of the wire harness W / H that branches from the main line to the branch line, the protective device 10 having a required shape is placed on the branched portion to prevent damage due to interference with other members.
[0004]
For example, a T-shaped protector made of a synthetic resin is used for a portion that branches into a T-shape. As shown in FIG. 9, the protective device 10 has a shape in which a T-shaped tube is divided into two parts, and a T-shaped main body 10a and a plurality of covers 10c, 10d coupled to the main body 10a by hinges 10b. , 10e, and the locking portions 12 of the covers 10c, 10d, 10e are locked by locking the protruding portions 11 provided on the main body 10a. In addition, a large number of grooves 13 that fit into the irregularities of the corrugated tube 2 are provided on the inner periphery of each end of the main body 10a and the covers 10c, 10d, and 10e.

Moreover, in the said protector 10, it is necessary to provide the groove | channel 13 fitted by the front-end | tip of the corrugated tube 2, and the mechanism which locks and latches the cover 10c, 10d, 10e to the main body 10a is required. It is necessary to provide it. Thus, the configuration is complicated and the cost is high.
[0010]
In addition, due to the complexity of the above configuration, the order of attachment to the wire harness 10a is also restricted, and the installation work is troublesome. That is, at the portion where the wire harness 10a branches in a T-shape, first, the main body 10a is externally fitted to the branch portion from below, and the cover 10c is covered, and then the cover 10e is covered and then the cover 10d is covered. In this way, there is a problem that the mounting order is restricted and the mounting work is troublesome.
[0011]
In view of the above problems, an object of the present invention is to provide an inexpensive wire harness protector that can be easily mounted and has a simple configuration regardless of the diameter of the wire harness and the form of the wire harness.
[0012]
