Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness molding protector used for accommodating and arranging a wire harness in a vehicle body / apparatus, and adjusting and maintaining the arranging posture of the wire harness. .

[0002]

2. Description of the Related Art A wire harness molded protector 1 (see FIG. 2) has a long groove body protector body 2 for accommodating a wire harness 10 in a groove, and a protector body 2 has an upper opening. , The side wall 4 of the protector body 2
A base 3 is provided which is provided with a lid 3 which opens and closes via a hinge portion 5 provided at the upper end of the wire harness, and which closes the lid 3 after housing the wire harness 10 to prevent the electric wire 11 of the housed wire harness 10 from popping out and protecting it. It has a structure.

The wire harness 10 is housed in the protector main body 2 by inserting the wire harness 10 into the molded protector 1 arranged and held on the molding drawing board of the wire harness 10.
Since the electric wire 11 is quickly inserted and set, the electric wire 11 in a "disassembled" state is closed from the protector body 2 and the lid body 3 is closed while the electric wire 11 is inserted. There is a risk that the electric wire 11 may be caught between the protector body 2 and the protector main body 2.
There is a known example shown in Japanese Patent Publication No. 111121.

That is, in this known example, the closed set side of the lid body 3 of the protector main body 2 (the side where the hinge portion 5 does not exist).
On the upper edge of the side wall 4 of the above, a "protrusion prevention plate 15", which is a flexible thin plate continuous in the longitudinal direction of the groove body, is erected, and inside the front end portion of the lid body 3, the protector main body 2 is provided. In this closed posture, a protrusion preventing plate 15 is forcibly laid down in the groove to push the electric wire 11 into the groove. In the figure, 13 is a female locking portion for closing and locking the lid 3, and 12 is a male locking portion.

[0005]

In the conventional device having the above-mentioned bite prevention mechanism, the strip-shaped thin plate protrusion preventing plate 15 is erected on the insertion side when the electric wire 11 is inserted into the groove. The work of inserting the electric wire 11 becomes difficult, and the fingertip may come into contact with and damage the fingertip, and the workability of wiring the protector main body 2 is poor, resulting in poor work safety.

Further, since the pop-out prevention plate 15 is a flexible thin plate, it may be easily plastically deformed by contact with other objects before the electric wire 11 is inserted, so that it is deformed to the outside of the protector body 2. Then, the lid 3 cannot be closed and locked, or the inside of the protector body 2 is deformed and the electric wire 11
Of the molding protector 1 and the high cost of molding the molding protector 1.

The present invention provides a wire protector for a wire harness that overcomes the above-mentioned drawbacks of the prior art.

[0008]

A molded protector for a wire harness according to the present invention which solves the above technical problem is "a protector body of an upper opening long groove body for accommodating a wire harness is provided on an upper edge of one side wall of the protector body. In a molded protector for a wire harness provided with a lid that opens and closes via a hinge to close the upper opening, a biting prevention inside the tip of the lid that gradually decreases in the direction of the hinge is prevented. In addition to providing the protrusion, the other side wall of the protector main body is provided with a protrusion accommodating cutout groove for receiving the bite prevention protrusion in the closed posture of the lid body ".

That is, in the molded protector for a wire harness according to the present invention, the intermediate portion or the tip portion of the above-described bite-in prevention protrusion is accommodated in the protrusion accommodating notch groove of the side wall of the protector body in the closed posture of the lid. It features a bite prevention mechanism to be set, and the protrusion storage cutout groove has a shape in which the side wall of the protector body is cut out, and the bite prevention protrusion penetrates the protrusion storage cutout groove to form a side wall. It may have a long shape that sticks out of it.

[0010]

The molded protector for a wire harness of the present invention having the above-mentioned bite prevention mechanism has a structure in which, when the lid is closed, the protector body does not enter the groove at the upper end portion of the protector body and rises up to the side of the protector body. The electric wire that is being caught is forcibly collected in the groove of the protector body by the inclined surface of the bite prevention protrusion and can be closed and locked in that state, so that the electric wire that sandwiches the wire between the protector body and the lid is It is possible to accurately prevent "bite".

Since the conventional preventive plate 15 is not present at the entrance portion of the protector body on the wire insertion side, and the substantial insertion opening becomes large, it is easy to insert the wire and the work safety is improved. In addition, the lockability of the electric wire insertion is improved more stably without obstructing the closure of the lid.
