Abstract

<P>PROBLEM TO BE SOLVED: To improve the manufacturing efficiency of a wiring harness even if cable protection is necessary, in a cable bundling tool applied to the wiring harness for a vehicle. <P>SOLUTION: This cable bundling tool 11 comprises a lower-side component 12 that bundles cables and is formed into a semicircle cross section gutter shape, and a lid component 13 that is fit to the lower-side component 12, accommodates the cables, and is formed into a semicircle cross section gutter shape. Five pieces of cable locking protrusions 15 are vertically protrusively formed on the internal peripheral surface of a lower-side body 14 at intervals. This configuration allows the bundling and protection of the cables to be simultaneously performed. Accordingly, even if the cable protection is necessary, the manufacturing efficiency of the wiring harness can be improved. The cable is brought into a bent state by the cable locking projections 15, and the adhesion of the cable to the cable bundling tool 11 is increased, thus making the installation position of the cable bundling tool 11 hardly displaced in the cable longitudinal direction. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an electric wire binding tool suitable for application to a wire harness for a vehicle and the like.

  12 is a perspective view of the binding band, FIG. 13 is a perspective view of an example of use of the binding band, and FIG. 14 is a perspective view of an example of use of the protector.

  Conventionally, as this kind of electric wire binding tool, as shown in FIGS. 12 and 13, an insertion piece 3 is formed at one end of the band body 2, and a through hole 4 is formed at the other end. A binding band 1 having a configuration in which a wavy engagement groove 8 is formed is used. That is, the band main body 2 is wound around the electric wire bundle 5, the insertion piece 3 of the band main body 2 is inserted into the through hole 4, the electric wire bundle 5 is tightened and locked by the engaging groove 8, thereby binding all the electric wires 6. (For example, refer to Patent Documents 1 and 2).

In general, the wire harness 7 has a circular cross section of the electric wire bundle.

  However, the binding band 1 does not have a function of protecting the electric wire 6. Therefore, when it is necessary to protect the electric wire 6, the electric wire protection member must be partially attached before or after the binding band 1 is attached, and the manufacturing efficiency of the wire harness 7 is reduced.

  Further, when the protector 9 is used, the cost increases by the material cost and attachment cost of the protector 9.

  An object of this invention is to provide the electric wire binding tool and electric wire binding method which can solve such a subject.

First, the invention of the wire binding tool according to claim 1 includes a lower part that converges and binds the electric wires, and a lid part that fits into the lower part and accommodates the electric wires. And
The electric wire binding tool according to claim 2 is characterized in that a locking means for fixing the lower part and the lid part is provided.
According to a third aspect of the present invention, the lid part is provided with a coupling foot that is coupled to the lower part.
According to a fourth aspect of the present invention, there is provided an electric wire binding tool according to the present invention, wherein the lower part and the lid part are formed with electric wire locking projections on at least one side.
Moreover, in the invention of the electric wire binding method according to claim 5, a plurality of electric wire binding tools having different electric wire binding sections are arranged and attached in the electric wire longitudinal direction of the wire harness.

  According to the present invention, it is possible to simultaneously bind and protect electric wires. Therefore, even when it is necessary to protect the electric wire, the manufacturing efficiency of the wire harness can be improved.

  Moreover, the wire bundle cross-sectional shape of a wire harness can be freely changed along an electric wire longitudinal direction according to a wiring space. Therefore, it becomes possible to route the wire harness at a lower cost compared to the case where the wire bundle cross section of the wire harness is changed using a dedicated protector.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
