Abstract

PURPOSE:To separate a wire harness into small parts, reduce the size of a jig table, and facilitate work by separating the wire harness into a main part and branched parts. CONSTITUTION:The part with diagonal lines is a main part 1 of a wire harness, having a branching part 1', from which it is branched to a plurality of wire bundles, and each wire bundle has a connector 1a-1e at the terminal part for an electric connecting device. These connectors 1a-1e are engaged with connectors 2a'-2e' connected at the root parts of branched parts 2a-2e, and at the terminal of each branched part 2a-2e is connected a connector 3. On a jig table 5, only the main part 1 of the wire harness is necessary to be produced. The jig table 5 can thus be smaller than conventional, so production work is facilitated, and work time is also reduced because the branched parts 2a-2e are not on it.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wire harness that can be used universally in many models.

[Prior Art] A wire harness is a bundle of electric wires used for internal wiring of automobiles, etc., and electrical connectors such as connectors and junction boxes assembled together for one vehicle or one block. be.

By forming the wiring portion as a wire harness as described above before assembling the vehicle, it is possible to increase the efficiency of wiring work.

As shown in FIG. 4, in the conventional wire harness, the wire harness material is routed on one jig stand, and the main body 10 and the plurality of branches 10a to 10e are integrated.
Manufactured by simultaneous wiring. code 3
4 is a connector housing, and 4 is a junction box, which is connected to the terminal of each main trunk or each branch as an electrical connector, and is connected to each electrical component installed in the vehicle (not shown).

In this case, the shape of the trunk 10 and the three positions of the branches 10a to 10e are set so that they can be connected to the connection terminals of each electrical component arranged inside the vehicle when installed on the actual vehicle. It is placed on the jig stand 11 and wired.

[Problem to be solved by the invention]

However, in the above-mentioned wire harness, it is necessary to increase the number of branches as the number of electrical components mounted on a vehicle increases. As the number of branches increases, the jig stand 11
There was a problem in that it was necessary to increase the size of the wire harness, making it difficult to manufacture the wire harness.

In addition, regarding one car type (in the case of automobiles, they are usually called by the same car name), there are differences in the format such as pan, sedan, etc.
There are dozens of types, depending on the destination and grade, from high class to low class. If we were to manufacture separate wire harnesses for each of these,
I can't stand the complexity in terms of work and management. Therefore, in order to reduce the number of types of wire harnesses, one type of vehicle is usually divided into several groups, and even if there are some differences, one type of wire harness is reused within the same group. When used in this manner, depending on the type of vehicle, there may be an unused connector like 10f shown in FIG. 4. The connector 10f is connected to the branch 1 of the wire harness so as not to interfere with the wiring.
0c with tape 6 (Fig. 5). However, doing this will not only make some parts of the wire harness thicker, but also
It also becomes a waste of work. Furthermore, even lower-class types require the same number of man-hours as upper-class types, resulting in a lot of waste.

The present invention was made in view of the above-mentioned facts, and it is possible to change the electrical components without making the jig stand thicker.

The purpose of the present invention is to provide a wire harness that can be used in common with many types of vehicles.

[Means to solve the problem]

In order to achieve the above object, the present invention has a main body of a wire harness with an electrical connector attached to each of a plurality of terminal parts, a base end connected to the electrical connector, and one or more terminal parts connected to each of the wire harnesses. A wire harness consisting of a branch section of a wire harness provided with an electrical connector connected to an external device, which selectively connects to a plurality of connection terminals of the electrical connector connected to the terminal section of the main body. Accordingly, it is possible to selectively attach a plurality of types of branch parts to the terminal part of the same main body.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. 1st
In the figure, the cross-hatched part is the main trunk 1 of the wire harness, which has a branch part 1' in the middle, which branches into a plurality of bundles of filaments. Connectors 1a to 1e as electrical connectors are provided at the terminal portions of each filament bundle.

Connectors 2a' to 2e' connected to the proximal ends of the branches 2a to 2e are fitted into these connectors 1a to 1e, and a connector 3 is connected to the terminal part of each of these branches.

FIG. 2 is a diagram showing the fitting of the connector 1a on the main body 1 side and the connector 2a' on the branch portion 2a side. These connectors
It is preferable that a and 2a' have locks to ensure secure connection. Further, although not shown in the drawings, each connector has a built-in female terminal fitting as a connection terminal.

The connectors 3 of these branch terminals are connected to electrical components (not shown) arranged in various parts of the vehicle.

In the present invention, only the main section 1 of the wire harness needs to be manufactured on the jig table 5.

Therefore, the jig stand 5 may be smaller than the conventional one,
Manufacturing work becomes easier and the work time is shortened because there are no branches.Also, this main body 1 is, for example, the highest grade of car model 1, that is, it has the most electrical components and the largest number of electric wires. It is formed as a circuit configuration corresponding to the object.

On the other hand, a plurality of types of branch parts are manufactured depending on the type of vehicle such as destination, grade, etc. Here, depending on the type, for example, the presence or absence of fog lights depending on the type, etc.
This refers to the presence or absence of power windows, the presence or absence of intermittent wipers, etc.

FIGS. 3(a) to 3(C) illustrate the differences in the branch parts depending on the type of vehicle, taking the branch part 2b as an example.

In the same figure (a), branch part 2b is used for the highest grade.
1 is connected to five connectors 31 to 35, each of which is connected to a mating electrical component (not shown).

(b) is an intermediate type, with three connectors 31 on the branch 2b2.
．． 33.35 are connected. The other side has connection parts with three connectors.

(C) is a lower species, with one connector 35 on the branch 2bs.
only connected. The other side has only a connection part with one connector.

The connector 1b of the main body 1 has a branch 2b of the top paper type! The wiring is designed to accommodate. Other branches 2b2.2ba
is connected only to necessary terminals of the terminals of the connector 1b, and no wires are connected to the other terminals. At other terminals of the main trunk 1, a plurality of types of branch parts are manufactured in the same manner as described above.

Note that depending on the type of vehicle, there may be cases where a branch portion is completely unnecessary, but in that case, it is sufficient to cover the connector on the main trunk 1 side.

Further, in addition to the connector, junction boxes 4a and 4b may be provided as electrical connectors at the end of one example of the main body.

The branch section configured in this manner has a size that is easy to automate in terms of the number of circuits, and if automated, it can be manufactured with even higher efficiency. In addition, since the products are manufactured according to the differences in each type of vehicle, there are no unnecessary connectors, and there is no wastage of parts or work.

Therefore, one type of main body l of the wiring harness can be used for more types of vehicles than before.
Reduce the number of wire harness types, simplify manufacturing and management,
Facilitation becomes possible.

With such a wire harness configuration, even if there is a design change, it can be dealt with quickly.

〔Effect of the invention〕

As explained above, according to the present invention, the wire harness is divided into the main body and the branch parts, so the wire harness is subdivided, and the jig stand only needs to manufacture the main body, making it smaller and easier to work with. become.

Additionally, the number of types of main parts is significantly reduced compared to conventional wiring harnesses, making management easier. Furthermore, differences between types of vehicles can be accommodated by changing the branch parts, eliminating wasted parts and work, and shortening the total work time.
