Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a band clip, and more specifically, it is used together with a corrugated tube for accommodating a plurality of electric wires and protecting the electric wires to prevent damage by the corrugated tube end of the electric wire bundle and to position the corrugated tube. Regarding band clips that can be regulated.

[0002]

[Prior art]

 As shown in FIG. 5, a corrugated tube configured as a flexible tubular body is externally fitted to the electric wire bundle 1 for the purpose of protecting or converging a plurality of electric wire bundles 1 over a predetermined area, and its end portion is As shown in FIG. 6, the position is regulated by winding with the vinyl tape 3 together with the wire bundle 1.

On the other hand, conventionally, banding clips for bundling that are used for bundling a plurality of electric wires are known. As an example of this band cup in FIG. 7, the band clip 5 is constructed such that the band body 4 made of a flexible material is curved in the direction of arrow A and the insertion portion 4a at the tip formed on the body 4 is provided at the other end. Inserted into the insertion port 5a of the lock part 5 provided, and by engaging the continuous serrated locking part 4b formed on the main body 4 with the elastic locking claw (not shown) formed on the lock part 5. It is configured so that the wire bundle 1 can be tightened. And, the banding with this band clip is more important than the conventional method of winding vinyl tape because it does not cause a shift between the electric wires.

[0004]

[Problems to be solved by the device]

 At this point, as is clear from FIG. 5, the corrugated tube had an edge 2a formed in contact with the electric wire surface at the terminal portion depending on the cutting position. When such an edge 2a is formed, since the edge is tightened to the surface of the electric wire with the vinyl tape, it may interfere with the electric wire passing through the tube end portion and damage the electric wire. Originally, such a situation would be serious for a corrugated tube used for the purpose of protecting electric wires.

The present invention has been made in view of the above-mentioned circumstances, and eliminates the drawbacks that occur in the use of the conventional corrugated tube by applying a band clip originally for the purpose of binding the wire bundle. It is an object of the present invention to provide an improved band clip for tying.

[0006]

[Means for Solving the Problems]

 That is, the object of the present invention is to have an insertion portion at one end in the length direction, insert the insertion portion at the other end, and connect the insertion portion to the required length from the vicinity of the insertion portion so as to have a serrated cross section. In a band clip having a lock part that engages with a stop part, a rib provided along one side of the locking part and a rib engagement part provided on the lock part for preventing the band from being inserted and displaced by the rib. This is achieved by a band clip, which is characterized by including a groove and a skirt portion extending in the width direction of the band.

[0007]

[Action]

 When the band clip is attached to the wire bundle, the skirt portion extending in the width direction of the band intervenes in the gap between the corrugated tube and the wire bundle, so that the skirt portion causes the edge of the corrugated tube to move. Since it is separated from the wire surface, damage to the wire surface due to the edge can be protected even if some force is applied in the axial direction of the wire bundle. Further, the band clip is attached to the end of the corrugated tube so as to come into contact with the end of the corrugated tube, so that the bundle of electric wires can be bound and the position of the corrugated tube can be restricted at a predetermined position.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is an overall perspective view of a band clip according to an embodiment of the present invention, FIG. 2 is a side cutaway view of a main part for explaining the usage state of the band clip of FIG. 1, and FIG. 3 is the same band clip of FIG. It is a principal part perspective view explaining a state. Since the wire bundle and the corrugated tube have the same structure as the conventional one, they will be described using the same reference numerals.

In FIG. 1, a band clip 10 made of a flexible material has a narrow width and a thin wall thickness so that a tip portion 11a can be easily inserted into a lock portion 15 described later. On the surface of the band body 11 facing from the vicinity of the tip to the other end, a locking portion 12 having a required length corresponding to the thickness of the electric flux bundle and having a continuous sawtooth cross section is provided. Further, a rib 13 extending along one side of the locking portion 12 is formed on the surface of the main body 11.

Further, on one side surface of the band body 11, a plurality of skirt portions 14 are extended in the width direction of the band clip 10 at substantially equal intervals. When wound around (see FIG. 2), the skirt portions may overlap due to the size of the wire bundle, so it is preferable to make the skirt thickness slightly smaller than the band thickness. A lock portion 15 is provided at the other end of the band body 11, and the lock portion 15 engages with the serrated locking portion 12 to fix the winding strength around the wire bundle 1. 16 is formed so as to have an elastic locking claw (not shown) so that a gap 17 for inserting the band exists between the surface of the band body 11 and the surface. In addition, the hook body 16 has an engaging groove 18 that engages with the rib 13 when the band body 11 is curved and the tip portion 11a is inserted into the lock portion 15 and wound around the electric wire bundle 1. Is formed to prevent winding deviation (lateral deviation) of the band body 11.

Now, in order to wind the band clip 10 around the wire bundle 1, the band clip 10 is bent so that the back surface opposite to the surface on which the locking portion 12 is provided is in contact with the wire bundle 1, and the tip portion 11 a is bent. When the rib 16 is inserted into the gap 17 between the hook body 16 and the surface of the band body 11, the rib 13 is engaged with the engagement groove 18 and the tip portion 11a is pulled from the lock portion 15, the hook body 16 is released. As shown in FIG. 3, the teeth of the locking portion 12 are passed one after another, and when the tip portion 11a is released when the wire bundle 1 is tightened to the required strength, the locking portion 12 is released at that time. And the latching body 16 mesh with each other, and the tightened state is maintained.

When tightening the band clip 10, the band clip 10 is applied to the end portion of the corrugated tube 2 which is inserted into the wire bundle 1 and placed at a predetermined position. It is inserted into the gap between the bundle 1 and the corrugated tube 2 and mounted so that the edge 2a of the corrugated tube 2 abuts on the skirt portion 14, and the rib 13 is engaged with the engaging groove 18 and tightened by the above method. I do. By engaging the ribs 13 with the engaging holes 17, the band clip 10 is prevented from being misaligned (laterally displaced) during or after tightening.

When the corrugated tube 2 is tightened, the edge 2a of the corrugated tube 2 comes into contact with the skirt portion 14 at the base of the lock portion 15 and is separated from the wire surface as shown in FIG. Do not damage. Even if the diameter of the corrugated tube is set to be approximately the same as the diameter of the wire bundle 1 and it is not possible to completely insert the skirt portion 14 into the gap without forming a sufficient gap between them, as shown in FIG. If the skirt portion 14 is inserted even a little, the edge 2a of the corrugated tube 2 contacts the skirt portion 14, so that the wire surface can be prevented from being damaged in the same manner.

Further, as the edge 2a abuts the side surface 15a of the lock portion 15 as shown in FIG. 2, the movement of the corrugated tube 2 is restricted and displacement of the corrugated tube 2 is prevented. The adhesive tape used for the purpose becomes unnecessary. FIG. 4 shows another embodiment of the present invention in which the skirt portion is not divided into a plurality of pieces as in the previous embodiment, but is made into one continuous sheet. Also in this case, if the skirt portion 24 is formed to be thinner than that of the band body 25 and is also thin in the extending direction, winding around the wire bundle can be performed smoothly.

[0015]

[Effect of device]

 As described above, according to the present invention, by extending the skirt portion in the width direction of the band body and inserting the skirt portion into the gap between the wire bundle and the corrugated tube, the end of the corrugated tube is inserted. The conventional wire damage due to the edge formed on the part is prevented. In addition, since the corrugated tube abuts against the band clip fixed to the electric wire bundle for tightening the electric wire bundle, the corrugated tube can be regulated in position and the conventional tape winding operation is not required. Therefore, standardization of work and productivity can be greatly improved. Further, the band clip of the present invention has versatility similarly to the conventional structure and can be applied to different wire bundle diameters to achieve the object of the present invention, so that the quality of the product can be improved.
