Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness with an electric component, which has an electric component such as a signal generator connected to one end thereof.

[0002]

2. Description of the Related Art Conventional wire harnesses with electric components of this kind are commonly used for electric components such as signal generators, and have a poor workability when the length of the drawing cord of the electric component is too long for manufacturing. Therefore, there are many cases where the wire harness main body is connected to the cord on the wire harness main body side.

FIG. 6 shows an example of the structure of a conventional wire harness with electric components of this type. In this wire harness with electrical components, a grommet 2 is attached in the middle of the wire harness main body 1, and a signal is applied to the ends of the two cords 1a and 1b constituting the wire harness main body 1 on one side with the grommet 2 as a boundary. The cords 4a, 4b of the electrical component 3 made of an electronic source are connected to the wire harness main body 1 at different positions in the longitudinal direction by connecting portions 5a, 5b, respectively, and cover the connecting portions 5a, 5b. The outer periphery of the main body 1 is covered with a protective tube 6, and the cords of the remaining wire harness main body 1 are connected to the armature main body of a magnet generator (not shown) on one side with the grommet 2 as a boundary. , The outer periphery of the remaining wire harness body 1 is also covered with another protective tube 7,
Various connectors 8a to 8e are connected to the ends of the cords of the wire harness main body 1 on the opposite side of the grommet 2, and the outer periphery of the wire harness main body 1 between the grommet 2 and the connectors 8a to 8e is also protected. The structure is covered with the tube 9.

In such a conventional wire harness with electrical components, the cords 4a, 4b of the electrical component 3 are provided on one side.
Since there is a connecting work with the cords 1a and 1b of the wire harness main body 1, the crimping connecting work of the connectors 8a to 8e on the opposite side had to be performed at the final stage of the wire harness assembling work. Therefore, the connectors 8a-8
The crimping and connecting work of e has a problem that it is a work by a manual crimping machine so as not to damage the electric component 3.

In recent years, if a cord alone is used, an automatic crimping machine can automatically perform the work of cutting the cord, removing the coating, and crimping the terminal. Therefore, it is advantageous to crimp the terminal before assembling the wire harness. large.

Therefore, as shown in FIGS. 7 (A) to 7 (C), the protective tube 6 is composed of a small-diameter tube portion 6a and a large-diameter tube portion 6b having an inner diameter that can be fitted to the outer periphery of the protective tube 6, and the wire harness is formed. A method of connecting the cords 1a and 1b of the main body 1 and the cords 4a and 4b of the electrical component 3 has been proposed.

In this method, as shown in FIG. 7 (A), a small diameter tube portion 6a and a large diameter tube portion 6b are preliminarily provided on the outer circumference of the cord 4b of the electrical component 3 on the outer circumference of the small diameter tube portion 6a. 6b is fitted in a fitted state, and in this state, the cord 4b of the electrical component 3 and the cord 1b of the wire harness body 1 are soldered and connected using the connection terminal 10b to form the connection portion 5b.

Next, the cord 1a of the wire harness main body 1 is passed through the small diameter tube portion 6a of the superposed body of the small diameter tube portion 6a and the large diameter tube portion 6b so that the small diameter tube portion 6a and the large diameter tube portion 6a. 7B is moved to the connecting portion 5b side as shown in FIG. 7B, and in this state, the cord 4a of the electrical component 3 and the cord 1a of the wire harness body 1 are soldered using the connecting terminal 10a. The connection portion 5a is formed by connecting the components.

Next, the small-diameter tube portion 6a is held at that position, and only the large-diameter tube portion 6b is moved to the connecting portion 5a side as shown in FIG. To cover the connecting portion 5a. As described above, the small-diameter tube portion 6a and the large-diameter tube portion 6b, which are arranged so as to be displaced in the longitudinal direction of the wire harness main body 1, fix the adjacent portions with the tape 11 so as not to move in the mutually overlapping direction.

When the electrical component 3 and the wire harness main body 1 are connected in this manner, such a connecting work can be carried out without trouble even at the final stage of the wire harness assembling work, so that the connectors 8a to 8a for the wire harness main body 1 are connected.
The crimping and connecting work of e can be performed before the wire harness is assembled. Therefore, the crimping and connecting work of the connectors 8a to 8e to the wire harness main body 1 can be efficiently performed by using the automatic crimping machine.

[0011]

However, conventionally, the tape 11 is wrapped around the tape 11 so that the small-diameter tube portion 6a and the large-diameter tube portion 6b are fixed so as not to move in the direction in which they overlap each other. The roll had a problem that workability was poor. Further, the tape 11 has a problem that its durability is poor because the adhesive strength of the tape 11 deteriorates with the passage of time and the tape 11 falls off during use.

An object of the present invention is to provide a wire harness with electric components, which can fix the small diameter tube portion and the large diameter tube portion so as not to move in a direction in which they overlap with each other with good workability and durability. To do.

[0013]
