Abstract

(57) [Summary] It is possible to form a ridge on the surface of the insulating sheet of the tape-shaped electric wire, and to restrict the curvature of the bent portion when the tape-shaped electric wire is bent by the ridge. Another object of the present invention is to provide a tape-shaped electric wire capable of preventing the conductor from being cut.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tape-shaped electric wire that is used for wiring in, for example, the interior of an automobile.

[0002]

[Prior art]

 As a conventional structure of this type of tape-shaped electric wire (flat cable), there is a structure as shown in FIGS. That is, 1 is an electric conductor having a rectangular cross section (hereinafter, referred to as a conductor), and a plurality of conductors 1 are embedded and held in an inner portion of an insulating sheet 2 in a separated state. The tape-shaped electric wire 3 is used for installation along the wall surface, floor surface, etc. of, for example, the name of a vehicle compartment.

Then, the tape-shaped electric wire 3 needs to be curved or bent depending on the wiring location, and these curved formation and bending formation are made to correspond to the wiring location. It is shaped by using a press machine or the like.

[0004]

[Problems to be solved by the device]

 However, when the tape-shaped electric wire 3 is extremely bent by a press or the like as shown in FIG. 3, for example, the radius of curvature of the bent portion a of the conductor 1 becomes small, which causes There was a problem that the conductor 1 was easily cut at the bent portion a.

Further, in order to solve this problem, if the thickness of the insulating sheet 2 is increased, the excessive bending of the conductor 1 may be eliminated, but in this case, the weight of the insulating sheet 2 increases. However, there is a problem that the tape-shaped electric wire 3 becomes heavy and is not suitable for vehicle mounting.

[0006]

Means for Solving the Problems The present invention has been made in view of such a conventional problem. A ridge is formed on the surface of an insulating sheet of a tape-shaped electric wire, and the tape is formed by the ridge. An object of the present invention is to provide a tape-shaped electric wire that can prevent the conductor from being cut in advance so that the curvature of the bent portion of the electric wire can be regulated so as to be large when the electric wire is bent.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

In FIGS. 4 to 6, reference numeral 11 denotes a tape-shaped electric wire of the present embodiment. The tape-shaped electric wire 11 has a plurality of conductors 13 arranged in parallel inside the insulating sheet body 12 at regular intervals. It is buried. A plurality of ridges 14 each having a substantially semicircular cross section are provided on both the front and back surfaces of the insulating sheet body 12 so as to extend integrally with the insulating sheet body 12 along the longitudinal direction of the conductor 13. .

By thus integrally forming the ridges 14 on both the front and back surfaces of the tape-shaped electric wire, when the tape-shaped electric wire 11 is bent as shown in FIG. Since the curvature of the bent portion becomes large and therefore the bending curvature of the conductor 13 is restricted to become large, cutting (cutting) due to extreme bending of the conductor 13 can be prevented. In addition, in this embodiment, since the ridge 14 is provided as a means for ensuring a large bending curvature of the tape-shaped electric wire 11, the action of the ridge 14 significantly reduces the weight of the insulating sheet body 12. It also has the feature that it can be augmented without increasing.

[0010]

[Effect of device]

 As described above, the present invention provides a tape-shaped electric wire including a plurality of conductors 13 and an insulating sheet body 12 covering the conductors in an aligned state, in which the protrusions 14 are formed on both front and back surfaces of the insulating sheet body 12. Since this is an integrally formed tape-shaped electric wire, when this tape-shaped electric wire is bent, the curvature of the bent portion becomes large due to the overlapping action of the ridges 14 so that the bending curvature of the conductor 13 becomes large. Since it is regulated, it is possible to prevent cutting (cutting) of the conductor 13 due to excessive bending.
