Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protective tube for a wire harness used for accommodating and protecting a wire group of a wire harness and disposing the wire group on a vehicle body or the like.

[0002]

[Prior art]

 The wire harness protective tube is shown in FIG. 2. The axially incised longitudinally split tube body 1 (hereinafter simply referred to as the tube body 1) and the locking holes for locking the fitting holes (not shown) of the vehicle body or equipment. It consists of a wire harness clamp 2 having a portion 3 (hereinafter, simply referred to as a clamp 2). The wire group 8 is housed in the tube body 1, the tape winding 9 is applied, and the tube body 1 is rolled and set. The clamp 2 is attached to the vehicle, and the clamp 2 is locked to the vehicle body or equipment to maintain the posture of the wire harness arranged on the vehicle body and protect the stored wire group 8. Then, the clamp 2 is attached to the tube body 1 by attaching the mounting plate 10 at the lower end of the locking portion 3 to the tube body 1 and winding it with a tape winding 9A, or by fixing the clamp 2 or the actual opening 61-91212. As shown in Japanese Patent Publication No. 3, a method of covering with a plastic sheet and fixing it integrally with the tube body 1 is adopted.

[0003]

[Problems to be solved by the device]

 Among the above-mentioned conventional protective tubes for wire harnesses, the former one in which the clamp 2 is fixed by tape winding, the wire group 8 is housed, rolled and taped 9, and then the clamp 2 is positioned. Since the manual work of re-applying and fixing the tape winding 9A is required, the work until it is ready to be mounted on the vehicle body is complicated and the workability is unfavorable. Moreover, the tape winding 9A is manually operated. Therefore, the tape may be improperly wound, and the clamp 2 may be dislocated from the tube body 1 or displaced due to vibration of the vehicle body or the like.

Further, in the latter one in which the clamp and the tube body are integrated with each other by a plastic sheet, although the manual work of fixing the tape winding of the clamp in the former can be omitted, the clamp separately formed is separated from the tube. Since a special process of setting on the outer circumference of the body 1 and covering with a plastic sheet is required, the molding cost becomes high. The present invention provides a protective tube for a wire harness that solves the above-mentioned problems of the conventional technology.

[0005]

[Means for Solving the Problems]

 The wire harness protection tube of the present invention, which solves the above technical problems, is a wire harness in which a wire harness clamp having an engaging portion for a vehicle body / device is provided on the outer periphery of an axially cut longitudinally split tube body. In the protective tube for use, the clamp attachment hole can be passed through the vertically divided tube body in which the clamp attachment hole is formed at a predetermined position on the peripheral wall, and the locking plate that is shaped to prevent the clamp attachment hole from coming off. A structure in which the wire harness clamp is inserted from the inside of the clamp attachment hole and the locking part is projected from the tube body and is set in combination with a wire harness clamp in which a shape-shaped locking part is provided upright. Is a feature.

[0006]

[Action]

 The wire harness protection tube of the present invention having the above-described structure includes a vertically divided tube body having a clamp attachment hole formed at a predetermined position, and a wire harness clamp having an engagement portion standing on the engagement plate of the above requirements. When the wire harness clamp is inserted into the clamp attachment hole of the vertically split tube body, the locking part of the clamp protrudes from the outer circumference of the tube body and the locking plate at the lower end engages with the clamp engaging part. It is set inside the stop hole so that it will not come off. Then, insert the wire group into the vertical tube body with clamp, roll the tube body and set it by tape winding, and the locking plate inside the tube body is pressed by the stored wire group and the position is fixed, It can be installed on the vehicle body and equipment, eliminating the need for tape winding work and special processing to fix the conventional wire harness clamp.

[0007] The locking plate that is prevented from coming off by the clamp attachment hole and embedded with the electric wire group is mechanically and accurately fixed, so that the clamp is attached to the tube body in a stable manner, and the vehicle body or the like is stable. It will not come off easily due to the vibration of and the clamping performance will be stable.

[0008]

【Example】

 Hereinafter, a detailed description will be given based on examples. That is, referring to FIG. 1 showing an embodiment of the present invention applied as a wire harness for an automobile, a protective tube for wire harness of the present invention has a clamp attachment hole 7 formed at a predetermined position on a peripheral wall. The wire harness tube body 1 having the above is combined with another wire harness clamp 2 having the engaging portion 3 standing upright in the center of the engaging plate 6, and the engaging plate 6 is a clamp. The plate 3 has a size larger than that of the attachment hole 7 and serves as a plate that is prevented from coming off from the clamp attachment hole 7, and the locking portion 3 has a shape capable of passing through the clamp attachment hole 7.

Then, as shown in FIG. 1B, the clamps 2 each having the locking portion 3 at the head are inserted into the respective clamp attachment holes 7 of the tube body 1 from the inside of the tube body 1 to lock the locking portions. 3 is projected from the outer periphery of the tube body 1, and the locking plate 6 is attached to the periphery of the clamp attachment hole 7 so as to prevent it from coming off, and then the wire group 8 is housed in the tube body 1 to be attached to the tube body 1. 1 is rolled up, and tape winding 9 is applied to the outer circumference to set it so that it can be placed on the vehicle body. The locking portion 3 of the clamp 2 has a publicly known shape that locks the locking portion 3 such as a fitting hole (not shown) of the vehicle body in a one-touch manner. The head portion of the locking column 5 forms the locking portion 3 of the pair of elastic locking pieces 4 having an open leg shape, and the elastic locking piece 4 is lightly pushed into the clamp attachment hole 7 After passing, the elastic locking piece 4 returns to its free state and is fitted and locked in the fitting hole of the vehicle body.

The wire harness protection tube of the above-described embodiment has the above-described operation. That is, when the separate clamp 2 is inserted and set in the clamp attachment hole 7 of the tube body 1, the locking portion 3 of the clamp 2 projects from the outer periphery of the tube body 1 and is prevented from coming off in the clamp attachment hole 7. In order to fix the conventional clamp 2 to the tube body 1, the locking plate 6 existing inside the tube body 1 is pressed and fixed to the wire group 8 bound by the tape winding 9. The tape winding 9A and the plastic sheet coating process are no longer necessary.

Further, even when compared with the conventional structure shown in FIG. 2, since the mechanism that contributes to the cost is only the drilling process of the clamp attachment hole 7, the cost is substantially higher than that of the conventional structure. There is no such thing. The locking plate 6 of the clamp 2 is fixed to the clamp attachment part 7 by being prevented from coming off, and is pressed against the electric wire group 8 to be fixed. Therefore, the protruding posture of the locking part 3 from the tube body 1 is There is no risk that the clamp 2 that is mechanically accurately fixed and locked to the vehicle body will come off or be displaced from the tube body 1 and that the clamp function will be deteriorated.

[0012]

[Effect of device]

 As described above, in the wire harness protection tube of the present invention, in which the wire harness clamp is provided on the vertically divided tube body, the tape winding work and processing for attaching the wire harness clamp to the tube body are unnecessary, The workability in the state where it can be attached to the car body / device is improved, and the workability improvement can be achieved without increasing the cost, and the clamp performance of the wire harness to the car body / device is stabilized to improve the quality. There are various effects.
