Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting tool for exterior parts of a wire harness, and more particularly to a corrugated tube for a wire harness or a temporary binding circuit (hereinafter referred to as "electric wire bundle assembly") constituting the wire harness. The present invention relates to a wire harness exterior component mounting tool that is optimal for fixing a clamp to the outer periphery of a wire harness.

[0002]

2. Description of the Related Art Generally, an electric wire bundle assembly is an electric wiring system for forming a predetermined circuit by connecting a large number of electric wires, and various corrugated tubes and various corrugated tubes are provided around the outer circumference of the electric wire bundle in which covered electric wires are bundled. It includes exterior parts such as clamps fixed to the outer circumference of the corrugated tube.

Since it is difficult to specify the form of the wire bundle assembly, a workbench called a drawing board is used when fixing the exterior parts. A large number of jigs are erected on the drawing board. By fixing the electric wire bundle assembly to the drawing board through the large number of jigs, the form of the electric wire bundle assembly is specified and the exterior parts Was being installed.

By the way, in order to improve work efficiency,
It has been proposed that a jig capable of detecting a missing external component to be mounted is attached on the drawing board (see Japanese Patent Laid-Open No. 5-325672). The jig includes an arm portion pivotally supported by the drawing board, and an exterior component receiving portion that is integrally attached to an upper end of the arm portion and receives an exterior component,
After rotating the arm to bring the exterior part receiving part close to the specified part of the wire bundle assembly and receiving the exterior part with this exterior part receiving part, after positioning the exterior part in the wire bundle assembly, manual work I had to install the exterior parts. Further, a sensor is provided in the exterior component receiving portion, and this sensor prevents forgetting to attach the exterior component.

[0005]

In the above-mentioned configuration of the prior art, when mounting the exterior part on the wire bundle assembly, the exterior part is positioned on the wire bundle assembly, and the forgetting to install the exterior part is prevented. It becomes possible to do. However,
Although the jig having the above-described configuration can exhibit the positioning function and the attachment preventing function, the work of attaching the exterior parts itself was performed only by hand, and thus the workability could not always be improved. .

For example, when mounting a clamp fixed to the outer periphery of the corrugated tube, the corrugated tube is sandwiched between a pair of continuous clamp pieces which are opened in a semicircular shape and face each other, and one clamp piece is clamped. It is necessary to fit the locking portion formed on the arc end to the locking portion formed on the arc end of the other clamp piece to connect them. Further, in the above-mentioned conventional configuration, the jig is supported by one hand and one clamp piece of the exterior component is applied, and the other clamp piece is directly pushed into the one clamp piece, thereby the locking portion The stopper was fitted to. However, since the work of fitting the retaining part to the locking part was done manually, it puts a heavy burden on the operator's hands and fingers, and the condition of incomplete fitting (hereinafter, this state There is a problem that the product is flowed to the next process.

The present invention has been made in view of the above problems, and improves workability in mounting external parts, thereby reducing the burden on the operator and preventing half-fitting. It is an object of the present invention to provide a fixture for exterior parts of wire harness.

[0008]

In order to solve the above-mentioned problems, the structure according to claim 1 of the present invention comprises an erected portion which is erected on a drawing board on which an electric wire bundle assembly is laid. In the wire harness exterior part fixture, the positioning part is fixed to the standing part and has a positioning part for positioning the exterior part to be attached to the wire bundle assembly with respect to the wire bundle assembly on the drawing board. The portion includes a seat that holds the exterior component in a posture in which the exterior component is to be attached to the wire bundle assembly, and a fastener that cooperates with the seat to fasten the exterior component to the wire bundle assembly. It is an exterior component mounting tool for a wire harness, which is characterized in that.

According to a second aspect of the present invention, in the exterior component mounting tool for a wire harness according to the first aspect, the receiving means is provided with a detecting means for detecting the exterior component attached to the seat.

[0010]

According to the first aspect of the present invention, the exterior part is held by the seat, and the fastener is used in that state, whereby the exterior part is assembled into a wire bundle without the operator directly fastening the exterior part by hand. It can be assembled into a solid. In addition, claim 2
With the configuration described above, it becomes possible to detect the exterior part to be attached to the wire bundle assembly by the detection means attached to the seat of the positioning portion.
