Description

  The present invention relates to a protector for a wire harness, and more specifically, a relatively long protector that is externally mounted on a wire harness routed in an automobile has high strength against a vertical load, and the wire harness accommodated in the interior is reliably secured. It can be protected.

Conventionally, in order to protect a wire harness used for wiring of various electrical components mounted on an automobile, a protector made of a synthetic resin that houses the wire harness is provided.
As the protector, for example, in Japanese Patent Application Laid-Open No. 8-154324, as shown in FIG. 7A, a cover 1b that can be opened and closed on the upper surface is hinged to an upper portion of a bowl-shaped main body 1a having an upper surface opened. When the wire harness W / H is accommodated in the main body 1a and the cover 1b is closed as shown in FIG. 7B, the locking portion 1d of the cover 1b is attached to the cover of the main body 1a. A protector 1 configured to be inserted and locked to the locking portion 1e is shown (Patent Document 1).

In addition, when the protector that accommodates the wire harness is used for a straight portion such as a rocker portion of a floor panel of an automobile, for example, the protector made of an extruded product is suitable from the viewpoint of mold cost. Since the protector 1 of Document 1 is also linear and the cross-sectional shape is constant in the length direction, it can be manufactured by extrusion molding.
However, for example, in a protector arranged at a position where a vertical load is easily applied when the passenger gets on and off, such as the rocker portion, it is necessary to increase the section modulus of the protector to increase the strength of the protector.
If an attempt is made to increase the section modulus in a protector made of an extruded product, since the cross-sectional shape is constant in the length direction, the plate thickness and height of the protector must be increased uniformly throughout the protector. As a result, there is a problem that the material cost increases and the weight of the protector also increases.
Moreover, in the protector of an extrusion molded product, it is not possible to efficiently reinforce the ribs by erecting a portion that is easily subjected to a vertical load.

JP-A-8-154324

  The present invention has been made in view of the above problems, and has an object to provide a protector for a wire harness that has high strength against a vertical load and can reliably protect a wire harness housed therein. It is said.
