Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electrical wiring device for a vehicle.

[Conventional technology]

There are various types of automobiles on the market, and even within the same model, there are several grades. Different grades require different parts and equipment.

On the other hand, in addition to standard parts and devices, commercially available automobiles are equipped with specially equipped parts and devices, and it is possible to install specially equipped parts and devices at the user's request. .

These parts and devices contain many electrical parts, and therefore the electrical wiring for supplying electrical signals and power to the electrical parts may differ depending on the car model and the presence or absence of special equipment. must be taken as a matter of fact.

To deal with this, the following three responses can be considered.

(1) As shown in A in Figure 3, in addition to standard equipment, all possible special equipment OPT1, OPT2, OPT
3. Build electrical wiring that can connect electrical parts.

(2) As shown in Figure 3B, create separate electrical wiring for each different electrical component to be installed.

(3) As shown in Figure 3C, electrical wiring corresponding to standard equipment, OPT1, OPT2, corresponding to electrical parts installed depending on grade and special equipment,
Each electrical wiring of OPT3... is made separately, and the desired electrical wiring is formed by appropriately combining them.

In (1) above, from the perspective of each vehicle, there is a lot of waste as there are electrical wirings that are not used. In addition, regarding (2), the types of electrical wiring are enormous, considering the grade, number of special equipment, and combinations thereof.
It cannot be created in reality. Therefore, in reality, a combination of (2) and (3) is adopted. In other words, we have built some standard electrical wiring that incorporates electrical wiring for electrical parts that are often installed, corresponding to almost every grade, and we have also built some standard electrical wiring that incorporates electrical wiring for electrical parts that are installed at a low rate. Prepare electrical wiring for each special equipment, and use a combination of standard electrical wiring and electrical wiring for special equipment as necessary.

FIG. 4 shows an example of electrical wiring constructed in this manner, where 20 is standard electrical wiring and 40 is electrical wiring for special equipment, in this case a constant speed traveling device. Standard electrical wiring 20 includes:
Various lighting equipment, parking brake lamp 26
a, parking brake switch 26b, starter motor, starter switch 25a, horn, horn relay 22, vehicle speed sensor 24, stop lamp switch 27a, stop lamp 27b, etc. are connected, and electric wiring 40 for constant speed driving device.
These include a constant speed traveling device control circuit 41, a main switch 42, an actuator 43, a cancel switch 44, a horn switch 45, and a water temperature switch 46.
etc. are connected. The standard electrical wiring 20 and the electrical wiring 40 for a constant speed traveling device are combined by a connector 50.

[Problem that the invention attempts to solve]

However, when configuring the electrical wiring in this way, the standard electrical wiring 20 to the connector 50 are connected by electrical wires 51 to 59, and such electrical wires are not included in the standard electrical wiring 20. 51～
59 is useless for vehicles that are not equipped with a constant speed running device. As is well known,
Electrical wires weigh considerably, occupy a large amount of space, and are also costly. For this reason, it is desirable to eliminate as many unnecessary wires as possible.

Therefore, the purpose of the present invention is to configure electrical wiring for a vehicle by combining electrical wiring for special equipment with standard electrical wiring as necessary, and to eliminate the need for special equipment in standard electrical wiring. The aim is to reduce the number of electric wires used.

[Means for solving problems]

Therefore, the present invention is characterized in that a line for special equipment in standard electrical wiring is formed using a line in a junction box.

Specifically, the vehicle electrical wiring device of the present invention has the following features:
Junction boxes are used to centralize branch connections to form standard electrical wiring in vehicles. Then, in the junction box, a special equipment track is formed to connect the special equipment on the vehicle to the standard electrical wiring,
A connector is formed at the end of the special equipment line to which electrical wiring for special equipment, which is different from standard electrical wiring, is connected.

[Effect]

As a result, the special equipment lines in the standard electrical wiring are formed by the tracks in the junction box, and the special equipment electrical wiring is connected to the connectors at the ends of the lines as needed. Once connected, electrical wiring including special equipment will be configured.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show an embodiment of the present invention, with FIG. 1 being an electrical wiring diagram and FIG. 2 being an external view.

In FIGS. 1 and 2, 10 is a junction box, and 20 is a standard electrical wiring. As is well known, within the junction box 10 there are several branch paths ( (not shown) is formed. The standard electrical wiring 20 is connected to electrical parts, switches, sensors, etc. in the same way as explained in FIG. It is done by connecting it. In addition, Jyankushion Box 10
A tail lamp relay 21, a horn relay 22, and a fuse are also connected inside. Further, 23 is an ignition switch, 25b is a starter motor, B is a line connected to a battery (not shown), and IG is a line passing through the ignition switch 23, respectively.

As is clear from FIG. 1, in addition to branching paths for standard electrical wiring 20, special equipment lines 30 are also formed in the junction box 10 in the same manner as the branching paths. The special equipment line 30 is appropriately connected to each line in the standard electrical wiring 20 as shown by 31 to 39, and connectors 11 and 13 are formed at the other end. In this case, a constant speed traveling device is typically shown as the special equipment, and the electrical wiring 40 for the constant speed traveling device, which is the electrical wiring for the special equipment, is connected to the standard electrical wiring via the connectors 11 and 13. It is connected to the wiring 20. The electric wiring 40 itself for the constant speed traveling device is exactly the same as that shown in FIG. 4 above. Further, the connectors 11 and 13 may be combined into one.

In Figure 1, TC, FC, AC, and SC are shown with the electrical wiring for other special equipment omitted;
is for electrically controlled automatic transmissions, FC is for fuel injection systems of internal combustion engines, AC is for air conditioners, and SC is for power steering. Similar to the electric wiring for the constant-speed traveling device, these electrical wiring 40 for special equipment are formed as special equipment lines in the junction box 10, and are connected by connectors.

In this way, since the special equipment track 30 for connecting the special equipment electrical wiring 40 to the standard electrical wiring 20 is formed in the junction box 10 in the same way as a branch path, a new electrical wire is required for this purpose. There is no need to set up. As is clear from FIG. 1, the special equipment lines 31 and 32 connected to the connector 13 are connected to the connector 12 in order to receive signals from the starter switch 25a and the parking brake switch 26b into the constant speed traveling device control circuit 41. The special equipment line 3 connected to the connector 11 was newly formed during
3 to 39 can be formed extremely easily by simply adding branch shapes one by one to the branch paths formed in the junction box 10, and can be constructed with almost no increase in weight, space, or cost. be able to.

[Effect of idea]

As described above, according to the present invention, when the electric wiring of a vehicle is configured by combining the electric wiring for special equipment with the standard electric wiring as necessary, the special Since the lines for equipment are formed using the lines in the junction box, the number of electric wires for special equipment in standard electrical wiring can be reduced. Therefore, the amount of electric wires used in standard electrical wiring can be reduced, and the weight, space occupied, and cost of electrical wiring can be reduced.
