Description

  The present invention relates to a vehicle harness structure and an additional connection member.

  Many electric devices such as various lamps and motors and switch devices for operating these are mounted on the vehicle. These various electrical devices are connected to a wire harness for supplying electric power supplied from a battery or the like, a control signal for controlling these electrical devices, and the like. This wire harness includes a plurality of electric wires and connectors. The electric wire includes a conductive core wire and an insulating covering portion that covers the core wire. The connector includes a terminal fitting that is attached to the end of an electric wire and connected to a core wire, and a connector housing made of an insulating resin that houses the terminal fitting.

By the way, the wire harness routed in the vehicle needs to cope with the presence or absence of a function due to the difference in the specification of the vehicle. In such a case, the conventional wire harness copes with retrofitting of functional parts. Such retrofit of functional components is performed by adding a wire harness for each function or wiring a wire harness having a high mounting rate.
Further, in recent years, as a communication system for controlling a plurality of electrical devices mounted on a vehicle, a plurality of electronic control units that control each electrical device are connected by a common multiplex communication line, and the multiplex communication line is connected to each other. A multiplexed communication system is used in which multiplexed signals are exchanged and the operation of each electrical equipment is controlled based on the signals (see, for example, Patent Document 1).

  When the electrical equipment 501 and 505 which are functional parts are additionally connected to the wire harness provided with such a communication system, these are connected via various harness assemblies 503, 507 and 509 as shown in FIG. In general, the electrical devices 501 and 505 are connected to an electronic control unit (hereinafter referred to as an ECU (Electronic Control Unit)) 511 for electronic control.

For example, as shown in FIG. 9A, a harness assembly 503 to which one electrical device 501 is connected includes an ECU-side connector 515 and a device-side connector 517 attached to both ends of the electric wire 513. One electrical device 501 is connected to the ECU 511.
Further, as shown in FIG. 9B, the harness assembly 507 to which the two electrical equipment 501 and the electrical equipment 505 are connected includes an equipment-side connector 517 and an equipment-side connector respectively connected to the ECU-side connector 519 by electric wires. 521, and two electrical equipment 501 and electrical equipment 505 are connected to the ECU 511.
Further, as shown in FIG. 9C, the harness assembly 509 to which the electrical equipment 501 having a high mounting rate is connected is connected to the ECU-side connector 519 regardless of whether or not the electrical equipment 505 is connected. The device side connector 517 and the device side connector 521 are provided, and one electrical device 501 is connected to the ECU 511.

However, if a harness assembly is added to each additional functional component such as the harness assembly 503 and the harness assembly 507 shown in FIGS. 9A and 9B described above, the product number of the wire harness is increased. It will increase. If the number of the wire harness to be assembled increases, the assembly work in the wire harness assembly line becomes complicated, and the efficiency of the wire harness assembly work decreases. For this reason, there exists a problem that the mass productivity of a wire harness falls and the cost of each component and wire harness itself rises.
On the other hand, in the case of the harness assembly 509 shown in (c) of FIG. 9, the device-side connector 521 and the electric wire 513 are generated as component parts (so-called “discard”) that are not used even if they are routed in the vehicle. However, the waste of the wire harness increases, and this also increases the cost of the wire harness.

The present invention has been made in view of the above situation, and an object of the present invention is to provide a vehicle harness structure capable of making the wire harness part number common and eliminating the discarding of the wire harness.

The above object of the present invention is achieved by the following configuration.

It is retrofitted through an additional connecting member whose one end is branched and connected to at least the communication line or the signal line. Therefore, there are no discarded components in the basic harness.
Furthermore, the additional connection member can additionally connect an auxiliary device selectively attached to the attachment target vehicle to an arbitrary position of the basic harness. The retrofit of the auxiliary device by the additional connecting member can be applied not only to the manufacture of the vehicle harness but also to the basic harness of the vehicle harness arranged in the completed vehicle.
