Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness for an automobile, and more particularly, to reducing a space required for assembling a floor harness arranged on a floor portion of a vehicle body among various wire harnesses, and reducing the space required for assembling the harness. It is intended to share a part.

[0002]

2. Description of the Related Art Various kinds of electric parts are mounted on automobiles and the like, and a wire harness is used for connecting these electric parts. Wire harnesses are provided at various points on the vehicle body, and the wire harness provided on the floor portion (floor portion) of the vehicle body is called a floor harness. In a sedan-type vehicle or the like having a luggage room (trunk) at the rear part of the vehicle body, the floor harness is routed continuously from the floor portion to the luggage room.

[0003] FIG. 3 shows a layout of a conventional floor harness 1 at a rear portion of a vehicle body. The floor harness 1 is routed from a floor portion 5a of the vehicle 5 to a luggage room 5b provided at the rear of the vehicle body, and a portion where the floor portion 5a is routed is defined as a trunk line 1a. The floor harness 1 has a first branch line 1b routed to an upper luggage door 5c near the rear end of the floor portion 5a, and a luggage room 5a.
and a second branch line 1c routed around the bottom of b.

FIG. 4A shows the structure of a floor harness 1 in which a main line 1a and first and second branch lines 1b and 1c are formed continuously and integrally. The first branch line 1b is used to connect to a device provided in the luggage door 5c.
Is connected to On the other hand, the second branch line 1c is for connection to the equipment in the luggage room 5b, and is connected to a tail lamp 8, a turn signal lamp 9 (turn signal), etc. in terms of lamps. A normal wire harness W / H including the floor harness 1 is an assembly drawing plate 3 shown in FIG.
Is used to assemble a large number of electric wires d on various wiring jigs 4 erected from the assembly drawing board 3.

[0005]

As described above, since the floor harness 1 is routed without interruption to the periphery of the luggage room 5b after traversing the floor portion 5a of the vehicle 5, the routing route is also reduced. As a result, the overall length of the floor harness 1 has become very long. Therefore, a large special drawing board having a long width is required for assembling the floor harness 1, and the assembling work becomes large and time-consuming, and an installation place and a storage place for assembling the large drawing board are required. However, there is a problem that a large space must be secured.

[0006] Recently, there are many so-called brother cars that share a platform or the like that is a framework of a vehicle body and that are derived by appropriately changing a front grill, various outer panels, and the like. Such siblings also have different rear peripheral designs for each sibling, so the location of tail lamps and the like are different, and accordingly, a floor harness must be assembled for each sibling.

[0007] Therefore, although the trunk line portion is almost common, it is necessary to assemble floor harnesses having different forms of the first branch line and the second branch line for each type of sibling, and the number of floor harness part numbers increases. There is a problem that it is difficult to reduce the cost of each harness because the production efficiency of low-variety small-volume production is forced. Further, as the number of harnesses increases, production management work and the like also become troublesome, which causes a rise in cost. Further, large assembly drawings for assembling the floor harness also need to be aligned for each product number, and there is a problem that it is increasingly difficult to secure the installation space and the like for the above-described large drawings.

The present invention has been made in view of the above-described problems, and has been divided into a portion where a floor harness can be shared and a portion which is a dedicated portion, so that a floor harness can be assembled without using a large drawing board. Another object is to reduce the cost of the harness.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a floor harness routed from a floor portion of a vehicle body to a luggage room portion located at a rear portion of the vehicle body, to a trunk line routed to the floor portion. Divided into a first branch line routed to the luggage door side and a second branch line routed to the luggage room side, and a connector is attached to each of the trunk line terminal and the first branch line, the terminal of the second branch line. The circuits are connected by fitting these connectors, and the connector of the trunk line terminal is used as a common connector, while the connectors of the first branch line and the second branch line are changed in the equipment to be connected, so that the terminal insertion position into the connector is changed. The variable connector is changed, and the first branch line and the second branch line are changed according to the difference of the connection device on the terminal side, while the trunk line is changed according to the circuit change by fitting the common connector and the variable connector. It provides an automotive wire harness that is configured to be shared by invariant.

As described above, by dividing the floor harness into the main line, the first branch line, and the second branch line, the total length of the floor harness is shortened to the length of the main line, etc. There is no need to use a drawing board, and space for the installation location can be secured in the same manner as a drawing board having a normal size. In addition, the number of floor harness parts, which had been increased in response to the siblings' derivatives, differed only in the design near the edges, such as the rear, etc. Also, only the second branch line is a dedicated product corresponding to each brother car, so that the number of part numbers in the whole can be reduced, and the cost of the entire floor harness can be reduced accordingly.

The connection between the trunk line and the first and second branch lines is made by fitting the connectors together, and the connector at the terminal on the trunk line side forms a reference portion as a shared connector. On the other hand, each of the first and second branch lines has a variable connector attached to the terminal so that various circuits can be flexibly formed with respect to the common connector. That is, since the variable connector can be attached to any electric wire constituting the first or second branch line, the variable connector is used exclusively for a vehicle to which the first and second branch lines are applied, and is combined with the main line as a whole. Various types of floor harnesses can be formed.

The number of variable connectors to be attached to the first and second branch terminals corresponding to the number of common connectors of the trunk line is set according to the type of vehicle to be applied, and each connector may be one or two. It may be the above. Further, the sharing of the trunk line is not limited to the siblings, and if possible, it may be applied to other types of vehicles to further share the harness.
