DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness protector for use in automobiles, and more particularly, to a wire formed by connecting a bent main body to a lid which is connected with a thin hinge after passing through a wire harness. A protector for a harness, which makes it possible to lock the lid smoothly while restricting the body from falling down.

[0002]

2. Description of the Related Art Conventionally, wiring harnesses installed in automobiles have been used for the purpose of protecting the wiring harness from external interference materials and restricting the wiring line of the wiring harness.
A wire harness is penetrated and assembled inside a protector which is a resin molded product, and the protector is fixed to a vehicle body. As a protector of this type, usually, a lid is connected to the upper end of one side wall of a gutter-shaped main body via a thin hinge, and after penetrating a wire harness through the main body, the lid is closed and locked integrally with the other side wall of the main body. Protectors for molded wire harnesses are frequently used.

Since the main body of the wire harness protector has a gutter shape as described above, the side wall having the free upper end of the side wall easily falls down and tilts. Since the lock connection between the main body and the lid is made at the upper end of the side wall, if the side wall falls down and deviates from the proper position, the lock connection between the main body and the lid will be hindered.

[0004] As a proposal for solving this problem, Japanese Utility Model Registration No. 2583435 discloses, as shown in FIG.
A locking projection 2 is provided on the side wall 1a of the main body 1, a lid 3 is hinged to the side wall 1b of the main body 1, a locking projection 4 is provided at the tip of the lid 3, and a rib 5 protruding from the lower surface of the lid 3 is provided. Is formed on a tapered surface 5a that descends from the lid front end side wall 3a side toward the lid rear end side, and the front end of the lid 3 is closed on the side wall 1a of the main body, and the main body 1 tilts. The upper end surface of the side wall 1a is pressed by the tapered surface 5a of the rib 5, and the locking projection 4 is locked to the locking projection 2 on the side wall 1a side.

In the above publication, the lower end of the rib 5 protruding from the lower surface of the lid 3 is formed on the tapered surface 5a, so that the lid 3 is closed even when the side wall of the main body falls down. Then, the tapered surface 5a hits the upper end surface of the side wall 1a that has fallen, and the side wall 1a is pushed back toward the normal position. Side wall 1 pushed back and held in place
The upper end of a is sandwiched between the side wall 3a and the rib 5, and the locking projection 2 on the side wall is securely locked by the locking projection 4 on the lid side.

[0006]

However, according to the above-mentioned publication, the side wall 1a does not function when it falls over the width of the tapered surface 5a because the side wall 1a is greatly collapsed. As shown in FIGS. 4A and 4B, when the main body 1 ′ is bent, the lid 3 ′ is connected to one side wall 1 a ′ of the main body 1 ′ via a thin hinge 6. But the other side 1
The lid 3 'is not connected to b', and the upper ends of both side walls 1a 'and 1b' of the main body 1 'are free ends. For this reason, as shown in FIG. 4B, when the amount of inward fall of the side walls 1a 'and 1b' increases, locking of the main body 1 'and the lid 3' becomes more difficult.

The present invention has been made in view of the above problems, and has a structure in which a main body and a cover can be securely locked even when a side wall constituting a protector for a wire harness is greatly inclined. The challenge is to provide

[0008]

According to the present invention, a lid is connected to the upper end of one side wall of a gutter-shaped main body through a thin hinge, and the lid is formed after a wire harness is passed through the main body. A wire harness protector of an integrally molded product that is closed and locked to the other side wall of the main body, wherein the main body and the lid are bent along a wiring path of the wire harness, and one side sandwiching the bending point is The upper end of one side wall of the main body is connected to the lid via a thin hinge, and the other side is in a direction in which the main body and the lid are separated from each other, and locking holes are provided at both side edges in the width direction of the separated lid. A lock piece is protruded, and a flat plate-like fall prevention rib is protruded from a position near a bending point to a position corresponding to the lock piece on a surface which is an inner surface side when closed, while the locking hole is formed on an outer surface of a side wall of the main body. Provide a locking projection to lock on, When the chain, the collapse prevention ribs are providing configuration and to have a wire protector for harness cover while contact with the inner surface of the side wall of the body to the separating side from the bending point near the body is closed.

[0009] In the side wall of the protector for a wire harness in which the body and the lid are bent, the system between the size of the fall and the place of occurrence is a bending point on the side where the lid is not connected to the body via the thin hinge. It is in a relationship that the degree of falling increases as the distance from the vehicle increases. The fall prevention rib of the present invention is protruded from the vicinity of the bending point to a position corresponding to the lock piece. When the lid is closed, the fall prevention rib first contacts the inner surface of the side wall from the vicinity of the bending point, and the lid is closed. As the contact is made, the contact moves to the vicinity of the place where the lock connection is performed, and by the movement of the contact, the fall of the side wall is sequentially corrected.

That is, the point where the fall prevention rib first comes into contact with the side wall is near the bending point, and the correction by movement of the contact point is started at the point where the fall of the side wall hardly occurs. Even if the side wall has fallen greatly at a position away from the bending point, the correction of the side wall can be started regardless of the degree of the fall. Once the correction is started at a place where no fall has occurred, the contact point moves by closing the lid, and the correction proceeds sequentially to the place where the fall is large, and finally the lock connection And the correction is completed. By this correction, the side wall is returned to the normal posture, and the lock connection can always be reliably performed.

The locking piece of the lid is provided on the distal end side, and a positioning rib having a flat plate shape is protruded from the inner surface of the outer periphery at the bending position, and the rib is applied to the inner surface of the side wall on the inner periphery of the main body when the cover is closed. It is good to make it the structure which makes contact. By providing the lock piece on the distal end side, the connection force of the lock connection extends over the entire length of the protector, and the connection between the main body and the lid is further strengthened. Further, by projecting a plate-like positioning rib on the outer peripheral inner surface side of the bending position, when closing the lid, the positioning rib first abuts against the inner surface of the side wall on the side opposite to the hinge, and the lid is First, it is fixed at a normal position at the bending position, and is fixed at the bending position by being guided to the normal position at the separating tip. In this way, the positioning ribs guide the lid to the correct position over the entire length of the protector, thereby facilitating the subsequent locking operation.
