Description

  The present invention relates to a protector and a wire harness.

  A wire harness mounted on a vehicle such as an automobile includes a routing material and a protector used for protecting the routing material and fixing the wiring harness. For example, when the wire harness is disposed in an engine room, a space in which the wire harness can be disposed is limited because a device such as an engine and a strut housing are present in the engine room. When it is difficult to arrange the wire harness in a straight line, a wire harness that can be bent is used (Patent Documents 1 and 2). In the wire harness that can be bent, for example, a portion to be bent is formed into a bellows shape made of synthetic resin or rubber, or a portion to be bent is formed of rubber.

  As described above, according to the protector 1 and the wire harness 100 according to this embodiment, the pair of bellows portions 22 and 23 can be bent in the first direction with respect to the main body portion 21 by the pair of hinge portions 24 and 25. . Further, the bending side protector 2 can be bent in the second direction with respect to the receiving side protector 3 by the tip end portions 22 b, 22 d, 23 b and 23 d of the spatula portions 22 and 23. Drawing 7 is a figure showing the straight line state to the 1st direction of the protector concerning an embodiment. FIG. 8 is a diagram illustrating a bent state of the protector according to the embodiment with respect to the first direction. FIG. 9 is a diagram illustrating a linear state with respect to the second direction of the protector according to the embodiment. FIG. 10 is a diagram illustrating a bent state of the protector according to the embodiment with respect to the second direction. When the bending side protector 2 bends in the first direction with respect to the receiving side protector 3, as shown in FIG. 7, from the state where no external force is acting on the protector 1, as shown in FIG. , 25 around the main body 21, the bellows 22 and 23 rotate around the second direction. At this time, one of the bell portions 22 and 23 comes out of the receiving side internal spaces 3a and 3c and the other enters the receiving side internal spaces 3a and 3c according to the direction of bending. When the bending side protector 2 is further bent in the first direction with respect to the receiving side protector 3, the distal end portions 22b, 22d, 23b, and 23d are deformed in the rotating direction in which they are bent out of the second direction. Further, when the bending side protector 2 bends in the second direction with respect to the receiving side protector 3, as shown in FIG. 9, from the state where no external force is acting on the protector 1, as shown in FIG. Since the front end portions 22b, 22d, 23b, and 23d of the portions 22 and 23 are tapered, the front end portions 22b, 22d, 23b, and 23d may rotate around the first direction in the receiving side internal spaces 3a and 3c. The bending side protector 2 is inclined in the second direction with respect to the receiving side protector 3.
