Abstract

A protector is equipped with a first bent portion protecting part protecting a horizontally-bent first bent part of a wire group; a second bent portion protecting part protecting a downwardly-bending second bent part; a first cover part; a second cover part; and a first locking part, the first cover part being integrally linked to the first bent portion protecting part and being closed and locked, and the second cover part being integrally formed with, and developed on the same plane as, the first cover part and being bent downwardly and closed and locked after the first cover part is closed, and the second cover part being equipped with a second locking part.

First claim

The invention claimed is:

1. A protector configured to protect a bent portion of a wire group, the bent portion being routed to bend in a planar direction and then bend further in a downward direction, the protector comprising:
a first bent portion protecting part having a recessed groove-shaped cross section defined by three intersecting surfaces of the first bent portion protecting part and housing a horizontally-bent first bent portion of the wire group;
a second bent portion protecting part extending integrally downward from one end of the first bent portion protecting part, having a recessed groove-shaped cross-section defined by three intersecting surfaces of the second bent portion protecting part and housing a downwardly-bent second bent portion of the wire group;
a first cover part closing an open surface of the first bent portion protecting part;
a second cover part closing an open surface of the second bent portion protecting part; and
a first locking part positioning one end portion of a first corrugated tube or the wire group, the first corrugated tube protecting the wire group and being provided to another end portion of the first bent portion protecting part,
wherein the first cover part is integrally linked to a side surface upper edge portion of the first bent portion protecting part via a hinge part provided on a side surface of an outer circumference side of the first bent portion of the wire group, the side surface being adjacent to the second bent portion protecting part and, upon closing, is locked by a first cover closure provided between the first bent portion protecting part and the first cover part;
wherein the second cover part is integrally formed with the first cover part at a flexible joint, the second cover part being configured to extend in the same plane as the first cover part and configured to rotate in a downward direction about the flexible joint so as to be in a closed state with respect to the second bent portion protecting part and locked by a second cover closure provided between the second bent portion protecting part and the second cover part after the first cover part is closed; and
wherein an end portion of the second cover part, the end portion being on an opposite side from a side connected to the first cover part, is provided with one end portion of a second corrugated tube or a second locking part, the second corrugated tube protecting the wire group housed in the first bent portion protecting part and the second locking part positioning the wire group.

2. The protector according to claim 1 , wherein the first locking part is configured to enter into a valley portion of the first corrugated tube housed in the first bent portion protecting part and lock the first corrugated tube.

3. The protector according to claim 1 , wherein the first locking part is a tape winding locking part which locks the first corrugated tube housed in the first bent portion protecting part or the wire group by winding a tape therearound.

4. The protector according to claim 1 , wherein the second locking part is provided to a U-band part provided to the second cover part, the second cover part being in an open state and on a same plane as the first cover part, and wherein the second locking part is configured to enter into a valley portion of the second corrugated tube supported by the U-band part and lock the second corrugated tube.

5. The protector according to claim 1 , wherein the second locking part is provided as a tape winding locking part which locks the second corrugated tube abutting on an inner surface side of the second cover part or the wire group by winding a tape therearound, the second cover part being in the open state and on the same plane as the first cover part.

6. A wire harness, comprising:
the protector according to claim 1 ;
a wire group housed in the protector so as to be three-dimensionally bent;
the first corrugated tube covering a portion of the wire group extending outwardly in a horizontal direction from inside one end of the protector, wherein an end toward the protector-side is positioned by being locked or wound by a tape at the first locking part of the protector; and
the second corrugated tube covering a portion of the wire group extending outwardly in a downward direction from inside another end of the protector, wherein an end toward the protector-side is positioned by being locked or wound by a tape at the second locking part of the protector.

7. A wire harness, comprising:
the protector according to claim 1 ; and
a wire group housed in the protector to be three-dimensionally bent, wherein the wire group is positioned by being wound by a tape at the first locking part and the second locking part provided to both end portions of the protector.
