[Prior Art]

 With the mounting of electronic devices in automobiles in recent years, a wide variety of electrical components are associated therewith, and the number of filaments such as wire harnesses used for wiring of them is also enormous. Therefore, wire harnesses and other filaments are grouped together and stored in a protector to protect them from damage and electrical equipment failure.

In FIG. 5, a lid body d is connected to one side wall of a gutter-shaped protector body a made of a hard synthetic resin via a hinge portion e, and a plurality of protector body a are thin-walled. The flexible portion b is connected and the flexible portion b is provided with a plurality of slits c (Japanese Utility Model Laid-Open No. 63-131516).

Since it is configured as described above, when the wire harness w is housed in the protector body a as shown in FIG. 6, the lid body d is closed and the tape winding f is performed to close the protector body a. is fixed at the bottom plate a ₁ locking formed on an outer surface portion a ₂ of the protector body a in a hole g ₁ such as a panel g of an automobile.

However, as shown in FIG. 6, since the protector body a is attached to a corner portion of a panel or the like, the wire harness w ₁ above the flexible portion b where the protector bodies a and a are connected to each other is not There is no protector that is open and protects the wire harness w ₁ . Therefore, there is a possibility that the wire harness w at the corner, which requires the most protection, rubs against other parts and causes a failure.

Further, when the wire harness is mounted on the protector and packed, a twisting force may be applied to the flexible portion b, and in extreme cases, the wire harness may be damaged. Further, since the protector for the wire harness of the conventional example is integrated and large, not only the mold becomes large and the mold itself becomes expensive, but also only one mold can be carved for each mold. However, only one shot can be taken with one shot of the molding injection machine, resulting in poor productivity.

[0007]

[Problems to be solved by the device]

 In view of the above points, the present invention provides a protector for a wire harness used in a corner or the like, in which a bent portion can be freely bent within a certain angle range, and the bent portion is not twisted and divided into small parts. The purpose is to provide a protector for wire harness that can be produced by

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a pair of side plates formed on one of the gutter-shaped protector bodies with a pair of side plates, and a pair of side plates formed on the other gutter-shaped protector body. The engaging protrusions are extended to form the engaging protrusions, and the engaging protrusions are slidably locked in the elongated holes. The flexible portion is formed at the center of the lid body having the locking portion formed at the edge. Are provided, and the locking portions are respectively engaged with the locked portions of the protector body.

[0009]

[Action]

 A long hole is formed in each of the pair of side plates on which the locking portion of one gutter-shaped protector body is formed, and the pair of side plates on which the locking portion of the other gutter-shaped protector body is formed is extended and engaged. Since the engaging projection is formed and the engaging projection is configured to be slidably locked in the elongated hole, the lid body having the flexible portion at the center and the locking portion at the edge is formed. Even if is locked to the one protector main body and the other protector main body, the protector that accommodates the wire harness by sliding the engaging protrusion on the elongated hole with the flexible portion of the lid inside To bend.

【Example】

FIG. 1 is a perspective view of a protector A for a wire harness according to the present invention. In FIG. 1, one end of the side plate 1a of the gutter-shaped one protector body 1 made of a synthetic resin provided with a pair of side plates 1a in which engaging recesses 1b as locking portions are formed has a pair of long ends. The hole 1c is formed. The elongated hole 1c is formed in an arc shape toward the upper end of the side plate 1a with a width H ₁ slightly larger than the diameter H of the head of the engaging projection 2c described later. The long hole 1c opposite to the side the substrate 1d is slightly extended with tongues 1d ₁ is provided, the resilient locking piece 1e is formed outside the substrate 1d, the vehicle body (not shown) panel hole and engaging Constitutes a means.

The end portion of the other side plate 2a of the other gutter-shaped protector main body 2 made of a synthetic resin provided with a pair of side plates 2a in which the engaging recesses 2b serving as locking portions are provided is the protector main body 1 described above. An engaging projection 2c is formed outward at the tip end portion that is reduced and extended to a width B slightly smaller than the width D of the inner surface of the side plate 1a, and is also reduced in height. The engaging projection 2c constitutes a slide locking means with the elongated hole 1c of the protector body 1. Engaging protrusion 2c and the side facing the substrate 2d is slightly extended with tongues 2d ₁ is provided, outside the flexible locking pieces 2e substrate 2d is formed, engaging a panel hole of the vehicle body has a shown It constitutes a stopping means.

The width C of the lid body 3 made of a synthetic resin in which the strip-shaped flexible portion 3a is formed in the central portion in a direction intersecting the extension direction is set to be slightly wider than the width D of the protector main bodies 1 and 2. At the same time, the engaging projections 3b, which are locking portions, are provided upright at the side ends, and the engaging concave portions 1b and 2b of the protector main bodies 1 and 2 respectively constitute locking means.

Since the embodiment according to the present invention is configured as described above, when in use, as shown in FIG. 2, first, the pair of engaging protrusions 2c, 2c of the other protector body 2 are pushed inward and narrowed. The engaging projections 2c are engaged with the long holes 1c of the protector body 1 respectively.

[0014] Then, each is positioned behind the pair of long holes 1c a pair of engaging projections 2c, and Wa ear harness W accommodated in the protector body 1 and 2, each of the tongues 1d _1, 2 d ₁ and The wire harness W on it is wound by tape 4 and fixed (see FIGS. 2 and 3).

Next, the engaging protrusions 3b of the lid 3 are locked to the engaging recesses 1b and 2b of the corresponding protector bodies 1 and 2 to fix the lid 3 to the protector bodies 1 and 2. Then, as shown in FIG. 4, the flexible locking pieces 1e and 2e of the protector bodies 1 and 2 are bent near a right angle in accordance with the angle of the vehicle body to be attached and fixed to the panel holes of the vehicle body (not shown) to complete the attachment. To do.

At this time, the bent portion W ₁ of the wire harness is located at the end of the elongated hole 1c of the protector body 2 by the engagement protrusion 2c of the protector body 2 and serves as a guide. Therefore, even if the twisting force is applied to the bent portion W ₁ of the wire harness, the bent portion W ₁ of the wire harness is not damaged by the force.

When the wire harness is bent in the direction opposite to that shown in FIG. 4, when the wire harness is wound around the protector main bodies 1 and 2, the engaging projection 2c is positioned closer to the end of the elongated hole 1c. Just roll it up. In the embodiment according to the present invention, the engaging protrusion 3b is formed on the lid body 3 as a locking portion, and the engaging recesses 1b and 2b are formed on the protector main bodies 1 and 2 as a locking portion. Although configured, the engaging recess may be formed in the lid body 3 and the engaging protrusions may be formed in the protector main bodies 1 and 2 to configure the locking means.

[0018]
