Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mounts a wire harness on the outer circumference of a wire harness and locks a protruding locking portion to a vehicle body / device to adjust the posture of the wire harness to be mounted on the vehicle body. The present invention relates to a band-type clamp for a wire harness used for holding it.

2. Description of the Related Art Band-type clamps for wire harness are
A band base is provided at an end of a winding band that can be wound around the outer periphery of the wire harness, and a locking portion that is fitted and locked in a fitting hole of a vehicle body or the like is provided upright on the band base and the band of the band base is provided. It has a basic structure in which the winding band is locked in the insertion locking hole. However, since it is substantially difficult to align the locking portion of the clamp fixed to the outer periphery of the wire harness and the fitting hole on the vehicle body side with "pitatsu", it is disclosed in Japanese Utility Model Laid-Open No. 1-116522. , There is a type in which the locking portion is slidable in the longitudinal direction of the band.

That is, in this known example, as shown in FIG. 3, a clamp main portion 12 having a locking portion 2, a connecting portion having a slide hole 23 in the band longitudinal direction between the band base 4 and the winding band 1. The band member 10 provided with 24 is a combination of two separate members, and the clamp main portion 12 is provided in the slide hole 23.
The structure in which the protruding position of the engaging portion 2 on the wire harness 3 can be adjusted by a slight amount by fitting and setting the lower end of the mounting main body 12 and sliding the clamp main portion 12 in the mounting posture along the slide hole 23. It has become.

[0004]

In the structure of which the position of the locking portion 2 can be adjusted in the above-mentioned known example, the length of the slide hole 23 is structurally limited, which makes it difficult to secure a long stroke. Since the position adjustable amount of the locking portion 2 is small, it is necessary to regulate the position of the locking portion 2 when the winding band 1 is wound, within an allowable range. Then, in order to prevent the clamp main part 12 fitted in the slide hole 23 from coming off, it is necessary to rotate the clamp main part 12 fitted in the slide hole 23 to a retaining posture, and the clamp main part 12 is required. The work of attaching the same to the band member 10 is complicated and the workability is poor. Moreover, since the connecting portion 24 is present, it is difficult to attach it to a wire harness having a small diameter.

Further, in order to prevent the distal end portion of the winding band 1 which is wound around the outer periphery of the wire harness from overlapping, overlapping the slide hole 23 and hindering the sliding movement of the clamp main portion 12. It is inevitable that the band insertion locking hole 5 is arranged in the radial direction of the wire harness 3 and the tip end portion of the winding band 1 is bent at 90 ° so that the band insertion locking hole 5 is tightly locked. The winding and tightening work of the winding band 1 requires a large force and is difficult to perform, and the band loosening may occur due to insufficient tightening of the winding band 1 and the band function may be deteriorated. The present invention provides a band-type clamp for a wire harness that solves the above-mentioned drawbacks of the prior art.

[0006]

A band-type clamp for a wire harness according to the present invention which solves the above technical problems is described as follows: "At the rear end of a winding band that can be wound around the outer periphery of a wire harness,
A band member provided with a band base having a band insertion locking hole in a winding direction of the winding band around the wire harness, and a separate clamp main part in which a locking part for a vehicle body / device is provided upright on the clamp base. In the combination with, in the winding band, while forming a clamp main portion guide portion extending from the band front end to the band rear end direction, the clamp main portion is fitted to the clamp main portion guide portion, and The both sides of the winding band are slidable, and have a band holding portion that holds the winding band in a vertical direction so as to prevent the winding band from slipping off. In a state in which the wearing band is wound around the wire harness, a wire harness press-contacting portion that disengages the clamp main portion in the mounting posture from the outer periphery of the wire harness is provided in the longitudinal direction of the winding band. The clamp main part is attached to the band member, wrapped around and fixed to the outer circumference of the wire harness, and the clamp main part with the locking part protruding is slid along the winding band to It is set to the position of and is locked to the vehicle body or the like.

[0007]

In the band-type clamp for a wire harness of the present invention having the above-described structure, the clamp main portion guide portion can be provided over the entire length of the winding band, so that the band member having the clamp main portion guide portion. The clamp main part attached to the wire harness is freely slid in a wide zone over substantially the entire length of the wrapping band wound around the outer periphery of the wire harness and set at an arbitrary position, and the locking part on the wire harness is projected. The adjustment amount of the position becomes extremely large, and the degree of freedom in adjusting the position of the locking portion with respect to the fitting hole of the vehicle body or the like is remarkably improved, so that the position restriction when winding and fixing the wire harness can be remarkably eased.

Since the winding band has a wire harness pressure contact portion for avoiding interference between the clamp main portion and the wire harness when the clamp main portion moves, the clamp main portion can slide smoothly. Yes, and
The clamp main part can be attached very simply by inserting it into the tip of the winding band, and the tip of the winding band is inserted and locked in the band insertion locking hole existing in the winding direction of the wire harness. Since the insertion and locking work is easy, the winding band is sufficiently tightened to the wire harness by simply pulling the band tip part drawn out through the insertion and locking hole. It is extremely unlikely that a defective winding will occur, and the winding performance will be stable. Further, since there is no portion that does not function as a band like the conventional connecting portion 24 on the outer periphery of the wire harness, it can be used for a wire harness having a small diameter.
