Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile wire harness.

[0002]

2. Description of the Related Art Conventionally, even if the wire harness for an automobile is the same vehicle model, the in-vehicle equipment is different depending on the product grade, the destination, etc. Things were being used.

For example, a conventional wire harness is shown in FIG.
The structure was as shown in. These are arranged so that electric wires that transmit electric signals and electric power between in-vehicle devices can be connected to each device as needed, and they are fixed by bundling them with an exterior material such as vinyl tape so that they do not scatter. The connectors 4, 5, 6, 7, 8, 9, 12, 13 are provided at the ends of the electric wires. Further, FIG. 4 shows the wire harnesses 20, 21, 22, and 23 that are installed at the same location on the vehicle body, and therefore the appearance is similar as shown in the figure, but as shown in FIG. The wiring of wires, that is, the harness circuit is different. In addition, the square frame surrounding the alphabetic characters shown in FIG. 5 indicates the connectors 4, 5, 6, 7, 8, 9, 12,
13, a line connecting the same alphabetic characters and a black circle mark indicate that the same circuit is electrically connected. However, the black circles do not specify the connection points, but indicate that the connection points may be anywhere on the same circuit.

The wire harnesses 20, 21, 22,
23 indicates, for example, whether or not there are two functions such as a panel light control function for adjusting the illuminance of night illumination of the meter panel and a function for supporting a specific destination.
Since there are four combinations, even wire harnesses installed at the same location in the same vehicle type require and use four different harness circuits.

[0005]

However, as described above, even in the case of vehicles of the same vehicle type, the in-vehicle equipment is different due to the difference in product grade and destination, and the wire harness corresponding to each is required. As a result, the number of wire harness products will increase, which will complicate production management.
As a result, problems such as short delivery times of wire harnesses and overproduction tended to occur.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a wire harness capable of simplifying production management of a wide variety of wire harnesses.

[0007]

A wire harness according to claim 1 is characterized in that a new circuit is constructed by short-circuiting an arbitrary circuit at an arbitrary terminal of a base harness corresponding to a plurality of circuit configurations. Is.

The base harness here means a wire harness which is preliminarily wired so as to correspond to a plurality of circuit configurations. As a specific example of short-circuiting an arbitrary circuit at an arbitrary terminal, it is preferable to connect a connector, but a conductor (including a semiconductor) such as a terminal or an electric wire may be connected, and there is no particular limitation. The wire harness according to claim 1 is an arbitrary terminal (at least 1) of a base harness.
Since an arbitrary circuit is short-circuited at a location), it is possible to form a wire harness that constitutes a new circuit. Even if a base harness having the same circuit configuration is used, it is already wired so as to correspond to a plurality of circuit configurations. Therefore, when another circuit is short-circuited, a wire harness that forms another new circuit is formed. You can also In addition, the number of arbitrary circuits to be short-circuited is not limited to one, and may be a plurality of circuits.

A wire harness according to a second aspect of the invention is characterized in that a short circuit connector for short-circuiting an arbitrary circuit at an arbitrary terminal of a base harness corresponding to a plurality of circuit configurations is provided to form a new circuit. .

The short-circuit connector is a connector that can be connected to any terminal of the base harness and that accommodates a conductor (including a semiconductor) such as a terminal or electric wire for short-circuiting any circuit in the connector housing. In the wire harness of claim 2, a new circuit can be constructed by connecting the short connector to the base harness. In other words,
A multi-product wire harness with different circuit configurations is formed by connecting multi-product short connectors with different placements of conductors (including semiconductors) such as terminals and wires to arbitrary terminals of one type of base harness. be able to.

A wire harness according to a third aspect of the invention has a short connector formed by fitting a male short connector and a female short connector to each other.

In the wire harness of claim 3, since the short connector is a connector in which two types of male and female connectors are fitted, the female short connectors having different arrangements of conductors (including semiconductors) can be replaced. It is possible to form wire harnesses of different types having different circuit configurations.

Therefore, a wide variety of wire harnesses can be handled only by the production management of the female short connector, which is relatively easy to produce a wide variety of products, and the management at the time of fitting to the base harness which is a common component.

[0014]

The present invention will be described in detail below with reference to the drawings. 1 to 3 show an embodiment of a wire harness according to the present invention.

As shown in FIG. 1, this wire harness 10 has a plurality of electric wires for transmitting electric signals, electric power, and the like between in-vehicle devices arranged so that they can be connected to each device as required, such as vinyl tape. The wires are bundled and fixed so that they will not scatter with an exterior material, and connectors (including terminals and connector housings) 4, 5, 6, 7, 8, 9, 12, 1 are attached to the ends of the wires.
3 is the same as the conventional one. Further, as the electric wire, a flat cable in which a plurality of circuits are integrally formed may be used.

As shown in FIG. 1, the wire harness 10 of this embodiment includes a male short connector 3 and a female short connector 2 for short-circuiting an arbitrary circuit at an arbitrary terminal of a base harness 11 corresponding to a plurality of circuit configurations. It is characterized in that a short circuit 1 which is fitted with each other is provided to form a new circuit.

The male short connector 3 comprises terminals and a connector housing. The male short connector 3 is connected to an arbitrary terminal of the base harness 11, a terminal is connected to the terminal of each electric wire, and the terminal is housed in a connector housing. Female short connector 2
Is composed of a terminal, a connector housing 2a, and a conductor (including a semiconductor) 2b. The terminals of the female short connector 2 are arranged so that they can be connected to any terminals of the male short connector 3 when they are fitted to the male short connector 3. In addition, a conductor (including a semiconductor) 2b, for example, an electric wire is mutually connected to any terminal to be short-circuited.

In this way, the female short connector 2 and the male short connector 3 can be fitted with one touch, which improves the assemblability of the wire harness 10, which is preferable.

The short connector 1 shown in FIG.
Although the male short connector 3 and the female short connector 2 are fitted to each other, the male short connector 3 and the female short connector 2 may be integrated (not shown).

Further, the wire harness 10 constitutes an arbitrary circuit by directly connecting only the conductor (including the semiconductor) 2b to an arbitrary terminal of the base harness 11 without using the short connector 1 as described above. (Not shown). This connection method is not particularly limited, and for example, soldering, ultrasonic welding, etc. are preferable.

The conductor (including a semiconductor) 2b
Is not limited to the electric wire as shown in FIG. 1, but may be a terminal formed by punching a flat cable or a metal plate or a bus bar (which may be integrally formed with the terminal) (not shown).

When the male short connector 3 and the female short connector 2 are used, for example, as shown in FIG. 2, the male short connector 3 of the base harness 11 is arranged in advance so as to correspond to a plurality of circuit configurations. By selecting and fitting the female short-circuit connector 2 having the four types of circuits shown in FIG. 3 in the order of FIG. 3A, FIG. 3B, FIG. 3C, and FIG. The wire harness including at least the circuits of FIG. 5A, FIG. 5B, FIG. 5C, and FIG. 5D described in “Prior Art” is sequentially configured.

The above-described four specific examples will be described in detail below with reference to the drawings. (Specific Example 1) In the one in which the female short connector 2 of FIG. 3A is fitted to the short connector 1 of the base harness 11 shown in FIG. 2, the two circuits of the terminal part f and the terminal part d are short-circuited, Since the two circuits of the part g and the terminal part e are short-circuited,
The wire harness includes at least the circuit shown in FIG. (Specific Example 2) In the one in which the female short connector 2 of FIG. 3B is fitted to the short connector 1 of the base harness 11 shown in FIG. 2, three circuits of the terminal portion d, the terminal portion e and the terminal portion f are Due to the short circuit, the wire harness includes at least the circuit shown in FIG. (Specific Example 3) In the case where the short connector 1 of the base harness 11 shown in FIG. 2 is fitted with the female short connector 2 of FIG. 3C, the two circuits of the terminal portion b and the terminal portion c are short-circuited, Since the two circuits of the part d and the terminal part f are short-circuited and the two circuits of the terminal part e and the terminal part g are short-circuited, the wire harness includes at least the circuit shown in FIG. 5C. (Specific Example 4) When the female short connector 2 of FIG. 3D is fitted to the short connector 1 of the base harness 11 shown in FIG. 2, the two circuits of the terminal portion b and the terminal portion c are short-circuited, Since the three circuits of the part d, the terminal part e, and the terminal part f are short-circuited, the wire harness includes at least the circuit shown in FIG.

In other words, as described above, an arbitrary circuit of the base harness 11, for example, terminals b, c, d, e, f, g of the male short connector 3 is connected to a conductor (including a semiconductor).
This means that it is possible to form an arbitrary harness circuit by making an arbitrary short circuit at 2b.
