[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is for attaching a wire harness to the outer periphery of the wire harness, and locking the protruding locking portion with a fitting hole of a vehicle body / equipment so as to arrange and hold the wiring harness. The present invention relates to a clamp, more specifically, to a band-type clamp for a wire harness, which has a wrapping band for wrapping and tightening around the wire harness.

[0002]

[Prior art]

 A wire harness band-type clamp has a shape in which a winding band is extended on the base part where a locking part that locks to the vehicle body and equipment is projected, and the winding band is wound around the outer periphery of the wire harness. The front end of the wire harness is passed through the band insertion lock hole of the base and locked, and is attached to the outer periphery of the wire harness at a predetermined position. Then, in an automobile assembly line or the like, an engaging portion of the clamp is engaged with a fitting hole or the like of a vehicle body to arrange and hold a wiring harness.

[0003]

[Problems to be solved by the device]

 When the above conventional wire harness band-type clamp is used for an automobile wire harness, the wire harness band-shaped clamp locking part that is previously attached to the outer periphery of the wire harness and the fitting hole of the vehicle body are It is practically difficult to align the position with the “pitt” when mounting on the vehicle body, and there is often a slight misalignment between the two. Therefore, to correct the misalignment, it is difficult to loosen the wrapping band and correct the position of the band-type clamp for the wire harness, or to "pull" or "push" a long and heavy wire harness. Alignment work is required, which is the main factor that hinders the wiring harness installation workability and installation work efficiency.

Further, the conventional wire harness band-type clamp has a one-touch locking structure in which the winding band is hooked and locked by the locking claws in the band insertion locking hole. Since the stopping force depends on the locking structure, in the case of a wire harness in which the wire bundle diameter is large and the weight is heavy, the winding band is loosened due to insufficient locking force, the clamp position is displaced, and The function of retaining and holding the lock may be deteriorated. The present proposal provides a band-type clamp for a wire harness that solves the above-mentioned problems of the conventional technology.

[0005]

[Means for Solving the Problems]

 The band-type clamp for a wire harness of the present invention that solves the above technical problems is described as follows: A pair of insertion locking portions that are provided are spaced apart from each other, and a clamp base portion in which the band insertion locking holes are arranged to face each other and a locking portion for the vehicle body / device are erected on the upper part, and the winding band is also provided. And a width of the band through hole is larger than the band width of the winding band, and the clamp main part has an adjustment allowance in the width direction. A structure in which the clamp main part is slidably mounted between the pair of insertion locking parts in the direction of the adjustment allowance, and the band insertion locking hole and the band through hole are put in a communicating state to be combined. " Is characterized by the wires in the combined state It is set on the outer periphery of the harness and the tip of the winding band wound around the wire harness is passed through the pair of insertion locking holes and the band through hole that are in communication with each other to lock and fix it. .

[0006]

[Action]

 In the wire harness band-type clamp of the present invention having the above-described structure, the clamp main portion having the width-direction adjustment allowance is slidably mounted between the pair of insertion locking portions on the clamp base side, and is wound. Since they are connected and combined with the clamp base through the wearing band, the combined connection functions as a band-type clamp for a single wire harness. Since the locking portion that is erected on the clamp main portion is slidable within the width adjustment range described above, the winding band is wound around the wire harness and is tightly attached. The position of the clamp main part can be adjusted.

Then, the winding band wound around the wire harness and inserted and locked by the pair of insertion locking portions becomes a two-point locking with a span between the insertion locking portions, and the two-point locking is performed. The clamping part of the clamp main part that exists between the two ends is supported by the external force that holds the wire harness. As a result, the locking force of the winding band is significantly improved and is more stable than that of the conventional structure in which the external holding force of the wire harness acts as a pulling load of the winding band.
