Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a binding tool used when a filament such as an electric wire is focused using a band.

[0002]

[Prior art]

 FIG. 5 (A) is a front view of a conventional binding tool. In the binding tool a, an insertion chamber e is formed in a base portion d on the other side of a binding band c formed with a continuous engagement protrusion b on one side from the free end c ′ and is flexible from the inner wall of the insertion chamber e. A locking piece f is provided, and a locking piece g is provided outside the insertion chamber e.

When the free end c ′ of the binding band c is inserted into the insertion chamber e, the insertion protrusion b is inserted so that the engagement protrusion b is locked by the flexible locking piece f projecting from the inner wall of the insertion chamber e. The size of the cross section of the chamber e and the size of the cross section of the free end c'of the binding band c are set, and the direction of the flexible locking piece f and the direction of the engaging projection b can be freely inserted in the insertion direction. The separation direction is set so as to prevent separation (see FIG. 5 (B)), (Japanese Utility Model Laid-Open No. 62-150366).

Since the conventional example is configured as described above, as shown in FIG. 6, the base portion d of the binding tool a is positioned on the portion where the wire harness w is to be bound, and then the binding band is placed. The wire harness w to be bound is wrapped around the free end c'of c and is inserted into the insertion chamber e to engage and lock the engagement protrusion b with the flexible locking piece f. Then, the locking piece g is inserted into the panel hole (not shown) to fix the binding tool a to the panel.

However, only by tightening the binding band c, the binding tool a moves on the wire harness w in the extension direction h of the wire harness and the position is not determined, and there is a drawback that the wiring work for the vehicle body panel becomes troublesome. .

[0006]

[Problems to be solved by the device]

 In view of the above-mentioned points, the present invention contemplates that when a filamentous body such as an electric wire is bundled by using a binding band and fixed to a vehicle body panel, it is preliminarily positioned on the filamentous body by temporary locking and then the binding bar is used. It is an object of the present invention to provide a binding tool that is fully locked by a cord.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention forms a locking portion with a panel on an outer surface of a base of a binding band in which an engaging portion is continuously formed in an extension direction, and has a serrated locking. In a binding tool provided with a binding band insertion chamber with a protrusion, a configuration is adopted in which a temporary locking plate for tape winding is connected to the base portion in a direction intersecting the extension direction of the binding band via a flexible portion. did.

[0008]

[Action]

 When the filaments, such as electric wires, are bundled using a binding band and fixed to the vehicle body panel, a temporary locking plate that is connected to the base plate of the binding tool via the flexible section in advance is wrapped around the wire harness. Then, the wire harness is temporarily locked to the wire harness, then the base plate of the binding tool is fitted to the temporary locking plate, and the wire harness to be bound at the free end of the binding band is wound and further inserted into the insertion chamber. And then tighten it to lock.

【Example】

 FIG. 1 is a perspective view of a binding tool A according to an embodiment of the present invention. The binding tool A made of a flexible synthetic resin has a U-shaped cross section in which the locking projection 3 is formed on the outer surface of the base 2 of the binding band 1 having the engaging portion 1a continuously formed in the extension direction. The outer wall 5 is formed, and a binding band insertion chamber 5a is provided which is open at both ends in the extension direction of the binding band 1.

A saw-toothed locking protrusion 4 is provided on the inner side of the outer wall 5 of the binding band insertion chamber 5 a facing the locking protrusion 3 and one end of the base portion 2 in a direction intersecting the extension direction of the binding band 1. A temporary locking plate 6 having an engaging projection 6a formed on the front edge is continuously provided on the edge via a flexible portion 6b. An engaging convex portion 2a is formed at an end edge facing the flexible portion 6b continuously provided on the base portion 2 and constitutes the engaging protrusion 6a and a locking means.

An interval P ₁ between the vertical wall 4 a and the saw-toothed locking projection 4 between the saw-toothed locking projections 4 of the binding band insertion chamber 5 a is equal to an interval P ₂ of the engaging portion 1 a of the binding band 1. The saw tooth-shaped locking projections 4 are set to be substantially equal to each other, and are dimensioned to fit in the engaging portion 1a (see FIGS. 1 and 2).

The locking protrusion 3 constitutes a locking means with a panel hole of an automobile (not shown). Since the embodiment according to the present invention is configured as described above, first in use, as shown in FIG. 3, the temporary locking plate 6 of the binding tool A 1 is placed on the portion of the wire harness W to be bound. The engaging projection 6a is positioned so as to face upward, and then the temporary locking plate 6 and the wire harness W are tape-wound 7 together as shown by the chain double-dashed line, so that the temporary locking plate 6 and the wire harness W are joined together. Temporarily lock.

Next, as shown in FIG. 3, the base portion 2 of the binding tool A is tilted in the direction D to lock the engagement protrusion 2 a with the engagement protrusion 6 a of the temporary locking plate 6, and the free end of the binding band 1. 1b is wound around the outer circumference of the tape winding 7 and inserted into the binding band insertion chamber 5a to be tightened and finally locked (see FIG. 4). Next, the locking projection 3 of the binding A is inserted into a panel hole of an automobile (not shown), and the binding A having the wire harness W bound is fixed to the panel of the automobile.

In the embodiment according to the present invention, the serrated locking projections 4 of the binding band insertion chamber 5a are formed on the inner surface of the outer wall 5, but they are formed on the binding band insertion chamber 5a side of the base 2. The engaging portion 1a may be formed on the side of the binding band 1 corresponding to. Further, in the embodiment according to the present invention, the engaging projections 6a are formed on the leading edge of the temporary locking plate 6, and the engaging projections 2a are provided on the base portion 2 to configure the locking means. May be omitted and the locking means may not be configured. In this case, in the so-called main locking in which the binding band 1 is inserted into the binding band insertion chamber 5a, the base 2 is integrated with the temporary locking plate 6 and fixed to the wire harness W.

[Effect of device]

 As described above, according to the present invention, when the filaments such as electric wires are bundled by using the binding band and fixed to the vehicle body panel, the tape is preliminarily locked by the tape and positioned on the filaments, and then the bundle is bound. The main feature of this tie is that it can be used for efficient wiring work without being displaced in the extension direction on the wire harness or rotating because it is permanently locked by the band.
