Wire harness installation structure
View Patent ↗There is provided a wire harness structure which prevents an extraordinary displacement of a wire harness, and immediately discharges water from the wire harness when the water such as rain water splashes on the wire harness so that the freezing of the residing water and undesirable cutting of wires due to the freezing can be prevented. At an extending portion 13 c of the wire harness, a strip-like plate spring 27 and the wires 31 are integrally combined together, and are covered with a mesh-like protective member 33 so that water will not reside therein. Even when water such as rain water splashes on the extending portion 13 c , the water is discharged through mesh holes of the protective member 33 , and will not reside in the extending portion 13 c . Therefore, the freezing of the residing water can be prevented, and the cutting of the wires 31 can be prevented from occurring.
1. A wire harness installation structure, comprising:
a wire in which a fixing-side connecting portion to be fixed to a door is provided at one end side of the wire in a wire extending direction thereof and a moving-side connecting portion to be fixed to a window attached to the door is provided at the other end side of the wire in the wire extending direction, the window being provided so as to be movable relative to the door, an extending portion of the wire between the fixing-side connecting portion and the moving-side connecting portion being provided with an excess length for allowing a movement of the window;
a strip-like plate spring is provided along the extending portion in an extending direction of the extending portion, and the extending portion being installed in a state that the extending portion is bent into a generally U-shape or curved shape and
a protective member which covers both of the extending portion and the strip-like plate spring so that water will not reside thereon,
wherein a fixing-side protector which is fixed to the door is connected to the fixing-side connecting portion,
wherein the strip-like plate spring includes a retaining hole and the fixing-side protector includes a retaining projection, the retaining projection integrally formed with the fixing-side protector and protruding from a surface of the fixing-side protector contacting the strip-like plate spring,
wherein the strip-like plate spring is connected to the fixing side protector by the retaining hole being engaged with the retaining projection,
wherein the strip-like plate spring is engaged at one end with the door and at an opposite end with the window,
wherein the window is movable relative to the door along on an upward-downward direction, and
wherein:
the strip-like plate spring includes notch portions, and
the fixing-side protector includes binding band through holes, and
wherein in response to the retaining hole being retained on the retaining projection, the notch portions are aligned respectively at positions of the binding band through holes.
2. The wire harness installation structure according to claim 1 , wherein the protective member is comprised of synthetic fiber forming into a mesh shape; and
wherein the synthetic fiber has a wear-resistance and flexibility.
3. The wire harness installation structure according to claim 1 , wherein the protective member is comprised of metallic filament forming into a mesh shape; and
wherein the metallic filament has a wear-resistance and flexibility.
4. The wire harness installation structure according to claim 1 , wherein the protective member has a hole or a slit for draining water.
5. The wire harness installation structure according to claim 1 , wherein a movable protector which is fixed to the window is connected to the moving-side connecting portion; and
wherein the fixing-side protector has a groove directed toward the window, and the extending portion of the wire is contained in the groove.
6. The wire harness installation structure according to claim 1 , wherein a movable protector which is fixed to the window is connected to the moving-side connection portion; and
wherein the fixing-side protector and the movable protector are arranged along the upward-downward direction.
7. The wire harness installation structure according to claim 1 , wherein in response to the window moving relative to the door along the upward-downward direction, the extending portion moves in the upward-downward direction according to the movement of the window, and
wherein the strip-like plate spring and the window are separated from each other and are different parts from each other.
