Description

  The present invention relates to a tube bending angle fixing holder and a wire harness that fix a corrugated tube in a bent state.

  Conventionally, in a wire harness routed in a vehicle, it may be necessary to route the route by bending the routing route by 90 degrees in a narrow routing space partitioned by a vehicle body panel with welding burrs protruding. In this case, it is difficult to add a function of fixing a state in which the corrugated tube that protects the electric wire group from the welding burr is bent at 90 degrees.

  Therefore, conventionally, the corrugated tube is bent at 90 degrees, and is held at a position away from the center of bending of the corrugated tube on both sides by, for example, two wire harness clamps shown in Patent Document 1, and the corrugated tube is bent at the center. Is fixed to each wire harness clamp body panel in accordance with the position bent at 90 degrees in the routing route.

  Patent document 2 takes up the problem which arises in use of the clamp of patent document 1 outside the use conditions mentioned above. That is, Patent Document 2 has a problem that the corrugated tube is crushed by edges of both side edges of the clamp body or the lid when the corrugated tube is bent extremely greatly on the side just of the clamp of Patent Document 1. The cable clamp that can solve this problem is proposed.

  8 and 9 are diagrams showing a cable clamp having a configuration substantially the same as that of Patent Document 2. FIG. As shown in FIG. 8, the clamp 20 has a semi-annular clamp body 21 and one end of a lid 22 connected by a hinge 23, and the other end is provided with a socket 24 provided on one side and the other. The lock piece 25 is locked. Each of the inner peripheral portions 21a and 22a of the clamp body 21 and the lid body 22 is provided with locking ribs 21b and 22b provided in three rows, and the clamp body 21 and the lid body 22 sandwich and hold the outer periphery of the corrugated tube. At times, the locking ribs 21b and 22b mesh with the annular groove on the outer periphery of the corrugated tube. Both side edges 21c, 22c of the inner peripheral portions 21a, 22a have a shape opened outward. As shown in FIG. 9, the clamp 20 holds a corrugated tube 27 through which the wire bundle 26 is inserted and is attached to the body side of the vehicle.

  As shown in FIG. 9, the clamp 20 disclosed in Patent Document 2 has both side edges 21 c and 22 c of the inner peripheral portions 21 a and 22 a when the corrugated tube 27 is bent sharply just outside the clamp 20 in use. Since it is formed in a shape that opens outward, both side edges 21c and 22c do not press the corrugated tube 27.

  That is, in the technique shown in Patent Document 1, the corrugated tube is bent at 90 degrees, and two wire harness clamps are externally fitted at positions away from the center of bending of the corrugated tube on both sides. In the clamp 20 disclosed in (1), the dimension from the bending center of the corrugated tube to the clamp mounting position can only be shortened.

  The clamp 20 disclosed in Patent Document 2 is such that the outer end of the corrugated tube through-hole is flared so as not to interfere with the sudden bending at the side. Does not have a function to fix.

  As described above, in the conventional clamp that holds the corrugated tube, there is a problem that no consideration is given to providing a function of fixing the rapidly bent state of the corrugated tube.

  The present invention has been made to solve the above-described problems, and provides a tube bending angle fixing holder and a wire harness that can fix a corrugated tube in a sudden bending state of 90 degrees by a set of two pieces. The purpose is that.

  In order to achieve the above object, the tube bending angle fixing holder according to the present invention includes a first divided body, a second divided body, and ends of mating surfaces of the first divided body and the second divided body. A hinge that connects the first divided body, a locking projection and a locking recess that are provided at the other ends of the mating surfaces of the first divided body and the second divided body, and that locks the other ends, and the first A semi-hole is recessed in each mating surface of the second divided body and the second divided body, and the corrugated tube is formed when the first divided body and the second divided body are combined. A connecting corrugated tube through-hole, and, if provided separately, of the connecting convex portion and the connecting concave portion, the connecting convex portion is an end face of the first divided body. And the connecting recess is provided on the outer peripheral surface of the second divided body. That.
