Abstract

PURPOSE:To eliminate the wiring work by securing the trunk section of a wire furnace to one block of a block molding while the branch section to another block, then arranging a connecting section with the branch section in the trunk section while a coupling means with electrical elements in the branch wire. CONSTITUTION:The trunk section 5 of a wire furnace has plural branch connecting sections 7 and burried in the upper portion of an inner panel 2. Further, the branch wire 12 of the wire furnace has the connectors 13, 14 and burried in the lower portion of the inner panel 3. Consequently, the upper portion of inner panel 2 is mounted to the lower section of inner panel, the male terminal sections 11 of respective branch connecting sections 7A, 7B are coupled with the connectors 13 of corresponding branch wire sections 12A, 12B. As a result, wiring work of wire furnace can be abolished and it is simply required to mounted an electrical element such as an auxiliary machine 4 to the lower section of inner panel 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wire harness device for a vehicle that integrates a component and a wire harness in a portion where a large number of electric wires are concentrated, such as an instrument panel of a vehicle.

1st place! Conventional vehicle wiring systems use a wire harness with a structure in which a large number of branch wires are derived from a trunk section in which a large number of electric wires are wrapped in tape, and the trunk section is routed in the space of the vehicle. It is fixed with a stopper, and connected to various electrical components via a connector provided at the end of the branch line and its counterpart connector.

Problems to be Solved In the above-mentioned wire convergence type wire harness, the diameter of the main wire portion increases, so it is difficult to route the wires in the limited narrow space of a car, As the population increases, this point becomes even more problematic. Furthermore, in addition to the possibility of slight deviations or waste in dimensions such as the length of the branch line and the mounting position of the terminal connector, many connectors at the end of the branch line must be joined in a narrow space such as inside an instrument panel. This requires a great deal of effort and time, and is extremely inefficient.

Means for Solving the Problems The purpose of the present invention is to provide a cable for vehicles that does not require a large wiring space such as the back of the instrument panel in the past, and in which it is extremely easy to connect the branch line end to electrical components. To provide a wire harness device, the solution is to fix a main part of a wire harness having a branch connection part to one block of a vehicle block molded product such as an instrument panel, and fix the main part of a wire harness having a branch connection part to another block. The branch wire portion of the wire harness, which has means for coupling with the branch connection portion and the means for coupling with the electrical equipment attached to the other one block, is fixed, and the one block and the other professional wire are connected to each other. It is characterized in that the main line part and the branch line part of the wire harness are connected by assembly with the hook.

For example, an automobile instrument panel is divided into a pad, an upper part, and a lower part, and a door consists of a door body and a cover plate. In this way, many parts of the vehicle also
It is constructed as a block molded product made of sheet metal or synthetic resin that is completed by assembling several blocks.

The present invention fixes the main part of the wire harness in one block of such a block molded product by embedding or the like,
The branch line section is fixed to another block, and the main line section is provided with a branch connection section for the branch line section, while the branch line section is provided with a coupling means (for example, a connector) to the electrical equipment attached to the block. Therefore, the wiring of the wire harness is completed at the same time as each block is assembled.

Therefore, unlike the conventional case, a large space is not required for wiring the wire harness, and the effective space within the vehicle interior can be expanded. In addition, electrical components such as various meters, auxiliary equipment such as motors, and switches need only be assembled at predetermined positions on the block, greatly improving work efficiency.

Another major effect is that the main line and branch line parts of the wire harness are fixed to separate blocks, which allows you to
Even if there is a change in the number or mounting position of on-vehicle electrical components due to classification, etc., it can be quickly dealt with by changing a part of the main line section or branch line section.

Embodiment In FIG. 1, 1 is an instrument panel (hereinafter referred to as
It is abbreviated as "Instrument Panel". ), 2 is the upper part of the instrument panel, 3 is the lower part of the instrument panel, and the instrument panel is constructed by assembling these blocks. 4 is a meter (auxiliary equipment) attached to the lower part of the instrument panel.

5 is the main part of the wire harness, which is connected to the upper part of the instrument panel 2.
Embedded and fixed in the recess 2a, and covered with the pad l. The trunk section 5 has a plurality of branch connections in its main body section 6. (7A,
7B...) are combined in a lattice pattern. As shown in FIG. 2, both the main body portion 6 and the branch connection portion 7 have a structure in which a plurality of parallel flat conductors (for example, copper plates) 8,8' are fixed to insulating films 9, 9'. The flat conductor 8' of the branch connection part 7 is connected to the hole 1 of the insulating film 9'.
It is permanently connected W to the flat conductor 8 of the main body part 6 through 0 by ultrasonic welding, spot welding, etc., and a male terminal part 11 is bent and formed at the end thereof.

Reference numeral 12 denotes a branch line portion of the wire harness, which is embedded and fixed in the lower part 3 of the instrument panel in correspondence with the branch connection portions 7A, 7B, . . . . This branch line portion 12 is formed by attaching a conductor such as the above-described flat conductor 8, a bus bar (not shown), or a normal electric wire along the shape of the lower part 3 of the instrument panel as shown in FIG. A connector 13 for the male terminal section 11 of the branch connection section 7 described above is fixed to one end of the connector 12, and a connector 14 for the auxiliary equipment 4 is fixed to the other end. The connectors 13 and 14 may be fixed with screws or known locking means, or
It may be integrally molded with the lower part 3 of the instrument panel.

As is clear from this embodiment, when the upper part 2 of the instrument panel to which the main part 5 of the wire harness is fixed is assembled to the lower part 3 of the instrument panel with screws (not shown), each branch connection part 2 is attached to the lower part 3 of the instrument panel. A,
Branch line portion 12A to which the male terminal portion 11 of 7B... corresponds,
It is inserted and coupled to the connector 13 of 12B.... Therefore, the conventional work of wiring a wire harness can be eliminated, and it is only necessary to assemble electrical components such as the auxiliary equipment 4 at predetermined positions in the lower part 3 of the instrument panel.

4 and 5 show other embodiments of the invention. Fourth
The trunk section 5' of the wire harness in the figure is a two-layered grid-like wire harness as shown in Figure 1, and if the depth of the wiring location is shallow, the configuration of the wire harness itself can be simplified. I go there to do it. The main line section 5'' in FIG. 5 is conveniently connected to the flat conductors 3a, 3b, etc. as shown in FIG. The male terminal portions 11 are formed by extending outward in a pattern without removing the outermost portions.

As is clear from the above, according to the wire harness device of the present invention, not only does it not require a large space for wiring the wire harness, but also the wiring work itself can be eliminated. This is extremely advantageous industrially because it is only necessary to attach electrical components to predetermined positions on a block molded product such as an instrument panel, and work efficiency is greatly improved.
