Abstract

PURPOSE:To execute change according to destination or grade, in an electric connection box, by cutting off sections connected to other electrical systems except the connected sections of the terminals of bus bars to one electrical system. CONSTITUTION:In a bus bar 16, the bus bar 11 of an IG(ignition) system having terminals A, F11, and F12 and the bus bar 14 of a + B (battery) system having terminals B, F14, and F15 are connected to each other with a bridge 17, and near the bridge 17, a terminal F13 is formed. When the bus bar 16 is cut off along dotted lines 51, 52 before the bar 16 is combined with an electric connection box, then the terminal F13 is connected to the only bus bar 11 of the IG system, and is separated from the bus bar 14 of the +B system. Besides, when the bus bar 16 is cut off along dotted lines 53, 54, then the terminal F13 is connected to the only bus bar 14 of the +B system, and is separated from the bus bar 11 of the IG system. Just by putting the bus bars 11, 11 into the electric connection box according to destination, grade, or the like, the composition and manufacturing process of a wire harness are not required to be changed, and the fitting of a short connector is also not required, and so a cost is reduced.

4 is a bus bar having terminals B, FI4 and FI5, 21 is a bus bar having terminals a1 and FIL, 22 to 25 are also 21
Bus bars 31 to 35 are Hiez.

The power source for the electrical junction box can be broadly divided into the IG (ignition) system and the 10B (battery) system. In the example in Figure 10, the system to the terminal is the IC system, and the system to terminal B is the +B system. . The terminal C system is connected to the RC system or the +B system depending on the destination, grade, model, etc. of the vehicle.

For example, when connecting the terminal C to the IC system, a branch line 43 is provided in the IC system electric wire 41 of the wire harness 40, and the branch line 43 is connected to the terminal C, as shown in FIG. Further, when connecting the terminal C to the +B system, a branch line 43 is provided to the +B system electric wire 44 of the wire harness 40, and the branch line 43 is connected to the terminal C as shown in FIG. Furthermore, when connecting terminal C to an IC system, a terminal section A' is provided on the bus bar 11 as shown in Figure 12, and Ao and C are connected.
may be connected by a connector 45.

As mentioned above, conventionally, if there is a terminal connected to one of multiple electrical systems depending on the destination, grade, etc.
The issue was resolved by changing the wire harness connection and installing a short connector.

〔problem〕

However, when changing the connection of the wire harness, it is necessary to change the configuration and manufacturing process of the wire harness depending on the destination, grade, etc., which increases costs. In addition, when installing a short connector, the number of circuits for installing the short connector increases, which not only makes it impossible to downsize the electrical junction box, but also increases the number of parts, which increases costs. Unnecessary management becomes a hassle.

[Means for solving problems and their effects]

SUMMARY OF THE INVENTION In view of the problems of the prior art as described above, an object of the present invention is to provide a method of manufacturing an electrical junction box for an automobile that does not require changing the connection of a wire harness or installing a short connector.

To achieve this object, the present invention provides a method for manufacturing an electrical junction box for an automobile, which has a terminal connected to one of different electrical systems depending on the destination, grade, etc. of the automobile, in which the terminal is connected to each of the different electrical systems. A feature of this method is to create a connected buspar, leave a connection point between the terminals of the busper and one electrical system, cut off the connection points with other electrical systems, and then incorporate the buspar into a box body. shall be.

In this way, it is extremely easy to change the wiring in the electrical connection box according to the destination, radar, etc., and there is no need to change the wiring harness connection or install a short connector.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
