Description

  The present invention is a protector for the exterior of a wire harness that is routed in an automobile, and in particular, can be used in common when the direction of wiring harness is different.

The wire harness routed in the automobile is inserted into a protector made of a resin molded product for the purpose of protecting the electric wire group from the path regulation and the external interference material.
The protector has a substantially bowl shape provided with a passage of an electric wire group surrounded by a bottom wall and both side walls, projects a tape-wrapped tongue piece from the bottom walls at both ends in the length direction, and the tape-wrapped tongue piece and the wire Adhesive tape is wrapped around the group to secure the wire group to the protector.

The wire harness routed to the door of the automobile is usually pulled out from a junction box housed in the lower front part of the driver's seat, and then routed to the door side through a protector.
There are two-door, three-door, and four-door types of automobiles, and the wiring harnesses routed to these doors have different wiring directions, so it is necessary to provide a door wire harness protector for each door type. There is. However, if a protector is formed for each door type, there is a problem that the cost increases.

On the other hand, in Japanese Utility Model Laid-Open No. 4-101217, a protector capable of guiding two sets of wire harnesses is provided. As shown in FIG. 7A, the protector 100 includes movable plate portions 101 and 102 provided with slits 101a and 102a on both sides of the support plate portion 100 via flexible portions 100a and 100b. As shown in FIG. 7B, the two pairs of wire harnesses W can be guided by separating the movable plate portions 101 and 102 with the slits 101a and 102a and bending them in the opposite direction.
However, although the protector 100 can regulate the insertion direction of two sets of wire harnesses W, it is necessary to regulate the direction of three wire harnesses for three doors and four wire harnesses for four doors.

Thus, since there has not been conventionally provided a protector that can be used in common for a 2-door, 3-door, and 4-door wire harness, as shown in FIG. 8, one protector 200 for 2-door is shared. And in 3 doors and 4 doors, wire harnesses are routed around.
That is, in the case of two doors, as shown in FIGS. 8A and 8B, a first passage 203 and a second passage 204 are provided at the center portion of the bottom wall 201 with a partition wall 202, and the first passage 203 has a right side. The wire harness W1 of the left door is passed through the door wire harness W1 and the second passage 204, and the wire harnesses W1 and W2 drawn from the outlets 203a and 204a are routed to the left and right doors branched to the left and right.
In the case of three doors, as shown in FIG. 8C, the wire harness W1 routed to the right door and the wire harness W3 routed to the rear door are passed through the first passage 203 in the protector 200 to the rear door. The wire harness W3 is pulled out from the outlet 203a and then folded back along the outer surface of the protector 200 and routed to the rear door.
In the case of four doors, as shown in FIG. 8D, after passing the left and right wire harnesses W1 and W4 and W2 and W5 through the first passages 203 and 204 in the protector 200, W4 and W5 are connected. After pulling out from the outlets 203a and 204a, the car is folded and then routed to the rear side of the automobile. After the route is restricted by a clamp or a protector (not shown) at the folded position, the vehicle is routed to the rear side.

  Thus, when the 3-door and 4-door wire harnesses are used in common for the 2-door protector 200, the wire harness W3 for the rear door of the 3 door, the routing part of the wire harnesses W4 and W5 for the rear left and right doors of the 4 door A lot of waste occurs, such as Z being required and clamping to the vehicle body side at the turn-back position. Moreover, there is a risk of interference with external members.

As described above, not only when the door types are different, but also when the branching directions of the wired wire harnesses are different due to the difference in the vehicle type, if a protector is provided for each wire harness, the cost increases, and the protector increases. If the wire harness is routed and used in common, there is a problem that the wire harness is wasted and other parts are required.
