Description

  The present invention relates to a harness protector that houses a wire harness routed in an automobile or the like and protects it from interference with the outside.

  When wiring a wire harness in an automobile or the like, the wire harness is often housed in a saddle-shaped harness protector and then fixed to a vehicle body or the like. As this type of harness protector, there are various types of harness protectors, such as those that accommodate a wire harness in a straight line, those that accommodate a curved shape, or a T-shape.

  When a wire harness is accommodated in such a harness protector, it is necessary to fix the wire harness so that it does not float or rattle. Conventionally, as a fixing method, in addition to fixing by tape winding, fixing using a binding band is often performed.

  FIG. 4 shows a conventional example (for example, see Patent Document 1) in the case of fixing using a binding band. The harness protector 110 has a bottom wall 111 and a pair of side walls 112 and 113 erected from both sides of the bottom wall 111 in the width direction. The harness protector 110 has a bowl shape with an open top surface. , 112 and 113 define a harness housing space P.

  A band insertion opening 115 through which the tip of the binding band 120 is inserted is opened at a position near one side wall 113 of the bottom wall 111, and the binding band 120 is engaged with the upper end of the other side wall 112 so as not to be displaced. A notch 118 is formed.

In order to accommodate and bind the wire harness W in the harness protector 110, for example, the front end of the binding band 120 is passed from the outside through the band insertion port 114 to protrude into the harness accommodating space P, and further the wire harness W Turned upward, passed through the notch 118 and inserted into the lock portion on the proximal end side of the binding band 120 extending along the outer surface of the bottom wall 111 and the side wall 113 of the protector 110 and locked. Thereby, the wire harness W can be fixed to the protector 110 by the binding band 120.

  By the way, in the case of this protector 110, since the wire harness W is pressed and fixed to the corner part 116 which the bottom wall 111 and the side wall 112 cross | intersect, depending on the thickness of the wire harness W, it is easy to produce rattling and the fixed state is not stable. There was a possibility.

  In view of the above circumstances, an object of the present invention is to provide a harness protector that can create a stable fixed state regardless of the thickness of a wire harness.

  The invention of claim 1 is a saddle-shaped harness protector in which a harness housing space is defined by a bottom wall and a pair of side walls standing from both sides in the width direction of the bottom wall. An inclined wall with the inner surface facing diagonally upward is provided on at least the lower half of one side wall in the vicinity, and the tip of a binding band that binds the harness accommodated in the harness accommodating space together with the protector is inserted below the inclined wall. It is characterized by providing a band insertion port for this purpose.

  Invention of Claim 2 is the harness protector of Claim 1, Comprising: The curved part which curved the said harness accommodating space when it planarly views was provided in the vicinity of the opening end of the longitudinal direction of the said protector. The inclined wall is provided on the side wall on the inner peripheral side of the curved portion.

  Invention of Claim 3 is the harness protector of Claim 1 or 2, Comprising: The side wall part perpendicular | vertical with respect to the said bottom wall is left above the said inclination wall, It is perpendicular | vertical with respect to the bottom wall. An obtuse bend is provided at the intersection of the side wall portion and the inclined wall.

  Invention of Claim 4 is a harness protector of any one of Claims 1-3, Comprising: The binding band which binds a harness through the said band insertion port in the upper part of the side wall which provided the said inclination wall. It is characterized in that an engaging portion is provided to prevent the positional deviation.

  According to the first aspect of the present invention, since the inclined wall whose inner surface faces obliquely upward is provided in at least the lower half of the side wall, and the band insertion opening is provided in the lower part of the inclined wall, By inserting the tip and overcoming the top of the side wall provided with the inclined wall and locking it to the base end of the binding band, the harness can be fixed by the binding band while pressing the harness against the inclined wall. .

  In this case, since the inclined wall faces obliquely upward, the band portion facing it can be pressed down so that the harness does not float upward and does not move to the opposite side wall, The fixed state can be stabilized regardless of the thickness of the harness.

  That is, when pressing and fixing to the bottom wall, it is possible to prevent upward lifting, while when pressing and fixing to the side wall, it is possible not to move to the opposite side wall side. Therefore, conventionally, the harness is pressed toward the corners of the bottom wall and the side wall to prevent the movement in the vertical direction and the movement in the horizontal direction. However, when pressed against the corner, no matter how much it is pressed, there is a tendency for space to remain inside the binding band, which causes the harness to move easily.

  On the other hand, in the present invention, the binding band is fixed while pressing the harness against the inclined wall facing upward. Can be maintained.

  According to the second aspect of the present invention, the curved portion is provided in the vicinity of the opening end in the longitudinal direction of the protector, and the inclined wall is provided on the inner peripheral side wall of the curved portion. The harness can be fixed while pressing against the inclined wall located on the side. Therefore, the return of the harness housed along the curved portion and pulled out from the opening end can be effectively suppressed by the binding band, and the linearity of the harness pulled out from the opening end can be maintained.

  According to the invention of claim 3, a side wall portion perpendicular to the bottom wall is left on the upper side of the inclined wall, and an obtuse bent portion is formed at the intersection of the side wall portion perpendicular to the bottom wall and the inclined wall. Therefore, the harness can be pressed and fixed to the obtuse bent portion, and a more stable fixed state can be created.

  According to the invention of claim 4, since the engaging portion for preventing the positional displacement of the binding band passed through the band insertion port is provided on the upper portion of the side wall provided with the inclined wall, the harness can be stabilized without being displaced. And can be fixed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
