Description

The present invention relates to a flat type wiring material.

Some wire harnesses mounted on a vehicle or the like include a rigid wiring material in order to facilitate the wiring work to the vehicle body. When transporting a long wire harness, it is desirable to fold it small so that it can be easily transported and store it in a small return box, but when folding a rigid wiring material, it exceeds its own elastic range. When a load is applied, bending habits are formed, so a process of extending the bending habits and removing the bending is required during the wiring work.

Patent Document 1 describes a wire harness including an exterior member including a flexible portion and an inflexible portion. By providing a flexible portion in the wire harness, bending and stretching can be relatively easy.

However, even in the wire harness described in Patent Document 1, if the curvature of bending is large, it is not possible to suppress the bending habit, and there is a possibility that man-hours for removing the bending may be required. Further, since the wire harness cannot be maintained in a linearly developed state by the wire harness itself, at least a flexible portion (bent portion) is required to be fixed to the vehicle body along the wiring path. It is necessary to fix each of the inflexible parts located at both ends, and there are problems in wiring workability and handleability, such as an increase in fixing points.

INDUSTRIAL APPLICABILITY The present invention has been made in view of the above problems, and it is intended to provide a flat type wiring material which can be folded into a small size and carried without bending habits, and which is excellent in wiring workability and handling. The purpose.

In order to solve the above problems, one aspect of the present invention is a plurality of flat wiring materials, each of which contains a conductor having a shape of being rigid and extending linearly, and which can be connected in series in a linear manner. It is provided with a flat electric wire and a string body that has elasticity and penetrates the inside of the conductors of a plurality of flat electric wires and is fixed to the flat electric wire located at each end of the flat wiring material. , The conductors of adjacent flat wires have a male-female connection structure for connecting to each other and an engaging portion that engages in a connected state, and in a state where adjacent flat wires are not connected. , It is a flat type wiring material in which the connection of adjacent flat type electric wires is guided by the stretched string body.

According to the present invention, it is possible to provide a flat type wiring material which can be folded into a small size and carried without bending habits, and which is excellent in wiring workability and handling.

The flat cording material according to the embodiment of the present invention is composed of a string body having elasticity and a plurality of flat electric wires having rigidity, and the plurality of flat electric wires are connected in series in a straight line. Functions as a flat cording material for books. As a result, when transporting the flat type wiring material, it is possible to divide the flat type wiring material into units of the flat type electric wire and fold it into small pieces, and when folding, a bent portion is required on the flat type electric wire. Because it does not, there is no bending habit. Further, even when a plurality of flat electric wires are connected in series in a straight line, the connection between the flat electric wires is guided by the string body, so that they are easy to connect, and after the connection, they are hard to come off and the shape is easy to maintain. Therefore, it is excellent in routing workability and handleability when mounted on a vehicle or the like.

Hereinafter, an embodiment for carrying out the present invention will be described with reference to FIGS. 1 to 4.

<Structure>
The configuration of the flat cording material according to the embodiment of the present invention will be described. FIG. 1 is a diagram showing a divided state of a flat cording material according to an embodiment of the present invention. FIG. 2 is a diagram showing a state after assembly of the flat cording material according to the embodiment of the present invention. FIG. 3 is a schematic vertical cross-sectional view of a connection structure along a central axis of a flat cording material according to an embodiment of the present invention. FIG. 4 is a diagram showing details of a connection structure of a flat cording material according to an embodiment of the present invention. As shown in FIG. 1, the flat wiring material 100 includes a plurality of flat electric wires 1 and a string body 2, and the plurality of flat electric wires 1 are connected in series in a straight line as shown in FIG. Assembled and functions as a wiring material. The flat wiring material 100 can be mounted on a vehicle as a wire harness ASSY (assembly) by attaching electric wires 10 and connectors 11 to both ends. The number of flat electric wires 1 is not limited as long as it is two or more.

The flat electric wire 1 includes a conductor 3. Inside the conductor 3, a passage is secured so that the string body 2, which will be described later, can penetrate in the longitudinal direction. The shape of the conductor 3 is, for example, a substantially prismatic shape as shown in FIG. The conductor 3 can be obtained, for example, by extrusion molding of a metal tube or bending molding of a metal plate, and the metal material used for the conductor 3 can be, for example, copper, aluminum, an alloy thereof, or the like. The flat electric wire 1 in the present embodiment is insulated by covering a portion of the outer surface of the outer surface when a plurality of flat electric wires 1 are linearly connected in series and assembled, except for an end portion, with an insulator 4. ..

The string body 2 passes through a passage formed inside the conductor 3 of the plurality of flat electric wires 1 and is fixed to the flat electric wire 1 located at each end of the flat wiring material 100 by the stopper 5. The stopper 5 is not particularly limited as long as the string body 2 can be fixed, but may be, for example, a plate material having a size capable of covering the opening surfaces at both ends of the flat cording material 100, or the conductor 3 or the string. It may be integrally molded with the body 2. The string body 2 has elasticity to the extent that a tensile force is generated in the state before assembly (divided state) in which the flat electric wires 1 are not connected to each other, and the flat wire rod 100 is not broken when it is folded into small pieces. It suffices to have, for example, a rubber cord or the like is used. The shape of the string body 2 is not particularly limited, but may include a round string, a flat string, and the like.

The conductor 3 includes a connection structure 6 and an engaging portion 8. As an example, the connection structure 6 is a structure for fitting and connecting adjacent flat electric wires 1 when a plurality of flat electric wires 1 are assembled as a flat wiring material 100, specifically. There is a male-female connection structure including a male-type connection structure 6A and a female-type connection structure 6B as shown in FIG. When the flat electric wires 1 are connected to each other by the connection structure 6, the plurality of flat electric wires 1 are developed in a straight line and function as the flat wiring material 100.

As shown in FIG. 4, the engaging portion 8 is composed of an engaging claw 8A and an engaging hole 8B in the present embodiment, and the engaging claw 8A engages with the engaging hole 8B to form a connection structure. It prevents the plurality of flat electric wires 1 connected by 6 from coming off after being connected.

The conductor 3 may be provided with an indent 7 in order to ensure an electrical connection between the flat electric wires 1 to be connected. The indent 7 may be formed inside the female connection structure 6B, for example, as shown in FIG. 4, or may be formed outside the male connection structure 6A, and as shown in FIG. 3, the indent 7 may be formed. It may be formed both inside the female connection structure 6B and outside the male connection structure 6A.

<Assembly method>
In the flat cording material 100, the string body 2 is bent and folded into small pieces in a divided state, and is stored in a through box.

When the operator takes out the flat wiring material 100 from the through box, the pulling force of the string body 2 causes the flat electric wires 1 to approach each other and induce a connection, and the flat electric wires 1 spontaneously approach each other and are in a semi-fitted state. Will be. The operator fits the connection structure 6 of the flat electric wire 1 in the semi-fitted state, and engages the flat wire 1 with the engaging portion 8. Alternatively, the flat electric wire 1 spontaneously approaches, fits, and then spontaneously engages with the engaging portion 8. In this way, the assembling work of the flat type wiring material 100 becomes easy. Further, since the engaging portion 8 suppresses disconnection of the adjacent flat electric wire 1 after assembly, the assembled shape is maintained. As a result, the handleability at the time of mounting on a vehicle or the like is improved.

<Effects, etc.>
The flat cording material 100 according to the present invention is composed of a string body 2 having elasticity and a plurality of flat electric wires 1, and the plurality of flat electric wires 1 are linearly connected in series to form a cording material. Can function. Therefore, when the flat wiring material 100 is transported, it can be divided into flat electric wire units and folded into small pieces. Since a bent portion is not required on the flat electric wire 1 when folded, it can be transported without creating a bending habit. Further, the string body 2 guides the connection between the flat electric wires, which facilitates the assembly work. Further, since the flat electric wires 1 have rigidity and are securely connected to each other by the engaging portion, the flat wiring material can maintain its shape without increasing the number of fixing points to the vehicle body. It is possible to suppress distortion of the shape that damages the vehicle body. As described above, the flat cording material 100 of the present invention can be folded into a small size and carried without bending habits, and is excellent in routing workability and handleability.
