Description

[Detailed description of the invention] [Field of industrial application] The present invention has a function to prevent the electric wires inserted into the wire harness protector from protruding outside the protector body, and a function to prevent the electric wires inserted into the protector for wire harness from protruding outside the protector body, and to prevent the electric wires from protruding upward when fitting the lid. The present invention relates to a wire harness protector having a function of accommodating a rising electric wire inside a protector body.

[Conventional technology and problems]

Conventionally, a wire harness protector that accommodates a wire bundle of wire harnesses to be routed, protects the wires, and prevents the wires from being disordered has conventionally been used as a wire harness protector.
The one shown in the figure has been used.

In the figure, a protector main body 1 has a bottom wall 2 and side walls 3A and 3B erected on both sides of the bottom wall 2, and forms a wire harness accommodation space inside.

A lid 5 is attached via a thin flexible hinge 4 attached to the upper edge of one side wall 3B.

Locking arms 6 are erected on both ends of the lid 5, and a protrusion 7 is provided at the tip of the locking arm 6.

On the other hand, both side walls 3A and 3B of the protector main body 1
is provided with an engagement frame 9 having a hole 8 into which the protrusion 7 fits when the lid 5 is superimposed on the protector body 1.

When the electric wire 10 is inserted into the main body 1 of the wire harness protector configured as described above, the lid 5 is rotated about the hinge 4 to overlap the protector main body 1, and the protrusion 7 is inserted into the hole 8. 5 is locked to the protector body 1.

In this way, the protector completely surrounds the electric wire 10 with the bottom wall 2, the side walls 3A and 3B, and the lid 5, so that the electric wire 10 can be protected.

However, if the electric wire 10 is not completely housed in the protector body 1 and the electric wire 10a protrudes from the side wall 3B, if the lid 5 is closed and locked, the electric wire 10a will be removed as shown in FIG. 10
a is exposed from between the lid 5 and the side wall 3B, and may come into contact with other parts in the vicinity and cause contact friction, or the electric wire 10a may be damaged due to a bruise or the like, resulting in electrical damage such as disconnection or shorts. Accidents such as failure, generation of abnormal noise, or damage to the protrusion 6 or the engagement frame 9 may occur.

In particular, when the wire harness protector is bent in the left-right direction as shown in FIG. The electric wire 10a is likely to cross over the side wall 3B, which is the outer wall of the electric wire 10a.

Therefore, in a wire harness protector having a bent portion, the above-mentioned accident is likely to occur.

The present invention has been devised to prevent such accidents.

[Means for solving problems]

The present invention provides a protector in which a cover is fitted to a protector body having a bottom wall and side walls on both sides of the bottom wall, and a wire harness consisting of a plurality of electric wires is housed inside the protector body. An electric wire that stands up toward the top of the side wall, and when the lid is fitted to the protector body, is pushed by the lid and falls down inside the protector body to accommodate the wire harness inside the protector body. A guide wall is erected.

[Effect]

With the above configuration, if there is an electric wire that gets into the side wall and starts to protrude from the bundle of electric wires inserted into the protector main body, it collides with the electric wire guide wall erected on the side wall and prevents the electric wire from protruding.

When the lid is closed, the wire guide wall collapses inside the protector, so that the wire colliding with the wire guide wall is also pushed into the protector as the wire guide collapses.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

Note that the same parts as in the conventional example are given the same reference numerals.

In FIG. 1, the protector main body 1 includes a bottom wall 2 and side walls 3A and 3B erected on both sides of the bottom wall 2.
constitutes a storage chamber for the bundle of electric wires 10, and the side wall 3B
A lid 5 is attached to a hinge 4 attached to the upper edge of the
As in the conventional example, a projection 7 is provided at the tip of a locking arm 6 erected at both ends of the lid 5, and an engaging frame 9 having a hole 8 into which the projection 7 is fitted is provided in the side walls 3A and 3B. It is.

However, in the present invention, a flat wire guide wall 11 is further integrally attached to the upper end of the side wall 3B via a thin wall portion 12.

The wire guide wall 11 stands up on substantially the same plane as the side wall 3B unless it is subjected to an external force.
As shown in the figure, if an external force is applied in the direction F,
It lies down using the thin wall portion 12 as a fulcrum, and changes from an upright state shown by a dashed line to a laid down state shown by a solid line.

When a bundle of electric wires is inserted into the main body 1 of the wire harness protector configured as described above, some of the electric wires try to climb over the side wall 3B and protrude outside, but some of the electric wires tend to hit the wire guide wall 11. This prevents protrusion.

Since the pressing force of the wires that come into contact with the wire guide wall 11 is weak, the wire guide wall 11 is not pushed down outwards, and the protector main body 1 is either lightly in contact with the wire guide wall or is caused by its own weight.
It falls into the wiring harness storage room inside.

When the insertion of the bundle of electric wires is completed and the lid 5 is rotated about the hinge 4 and overlapped with the protector body 1, the electric wire guide wall 11 is pushed by the lid 5 and falls down together with the lid 5, as shown in FIG. It becomes horizontal like this.

Therefore, the electric wire that was in contact with the electric wire guide wall 11 is also pushed by the electric wire guide wall 11 and is pushed against the protector main body 1.
The protector body 1 is sandwiched between the protector body 1 and the lid 5, and is not exposed to the outside.

Since the electric wires are not exposed to the outside, the lid 5 is not subjected to excessive distortion as shown in FIG. It will not be damaged.

The wire guide wall 11 is preferably installed on a straight section near the curved portion of the outer side wall 3C of the protector main body 1 where the wire is likely to protrude, but on both sides if there is a risk of the wire protruding. It may be provided at any location on the upper ends of the walls 3A, 3B.

Further, the cable guide wall may be installed at multiple locations.

Although the above embodiments have been described with respect to a hinged protector, the wire guide wall of the present invention can also be used with a protector in which the lid and the main body are separate.

〔effect〕

Since the present invention is constructed as described above, when the wire harness is inserted into the protector body, the electric wires that try to protrude outside the protector body hit the electric wire guides set up on the side wall, so that the electric wires are This prevents it from protruding outside the protector body.

The electric wire, which is prevented from protruding by the electric wire guide and is raised above the protector main body, is pushed by the electric wire guide which falls down when the lid is fitted, and is housed inside the protector main body.

Therefore, the wire harness protector of the present invention has a function of preventing the electric wires from protruding, and a function of pushing the protruding electric wires into the protector body when the lid is fitted. This eliminates the conventional risks of wire breakage, shot accidents, abnormal noises, and damage to the protector lock.

Furthermore, the cost of the wire harness protector is hardly affected, and the reliability of the wire insertion work is increased, resulting in improved work efficiency.
