Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connection box such as a junction box for connecting to a wire harness of an automobile, which can increase the versatility and the degree of freedom of a circuit to be housed in the electric connection box at a high density, and at the same time, simplify the operation. It is to be configured.

[0002]

2. Description of the Related Art Conventionally, circuits are densely housed in a junction box mounted on an automobile, but with the rapid increase in electrical components mounted on the automobile, the circuit becomes more complicated and larger, and the weight becomes larger. There is also a problem that the cost is increased due to the increase in the number of vehicles and the change in the circuit due to the increase in the types of vehicles.

In this type of junction box,
As schematically shown in FIG. 12, load side trunk circuits 3A, 3B, 3C, 3 are connected to power source side circuits 1A, 1B, 1C connected to a power source via fuses 2A, 2B, 2C and a relay 2 '.
D is connected and the trunk circuits 3A to 3D are connected to a large number of branch circuits 4
Branches A to 4K, and these branch circuits 4A to 4K are connected to electric wires of an external circuit such as an instrument panel harness, a floor harness, a roof harness, and a door harness as shown in the drawing. Although a small number of circuits are shown in the description, a large number of circuits are actually provided.

The power supply side circuits 1A, the load side trunk circuits 3A, and the branch circuits 4A of the junction box are often all formed by punching a bus bar of a conductive metal plate, but fuses and relays are often used. The circuit on the load side on the downstream side may be configured by pressure-connecting the pressure-contact terminal to the single core wire.

[0005]

When all the circuits in the junction box are formed by the busbars, it is necessary to make a mold for forming the busbars every time the circuits are changed.
It will be very expensive. Especially, recently, luxury cars, intermediate cars,
There are more types of vehicles for each grade and low grade vehicles (general vehicles), and even one vehicle type has different grades, so that the circuit configuration accommodated in the junction box is extremely diverse. Therefore, if these various types of circuits are formed with bus bars, the cost will be extremely high as described above, and
The number of manufacturing days is long, and there is a problem that it is difficult to easily change the circuit.

On the other hand, if the circuit is composed of the single core wire and the pressure contact terminal on the downstream side of the fuse and the relay, it is not necessary to make a mold as compared with the bus bar, and the degree of freedom of changing the circuit is increased to some extent. However, even when a circuit is composed of a single-core wire and a pressure contact terminal, it is necessary to wire the single-core wire in the box according to the circuit configuration, and therefore it is necessary to form an insulating plate provided with a wiring groove for the single-core wire. In addition, the wiring work itself is complicated and time-consuming, and it is difficult to shorten the number of manufacturing days in this case as well, and it is not possible to significantly reduce the cost.

The present invention has been made in view of the above problems, and is to improve the internal circuit of an electric junction box such as a junction box so that the circuit can be generalized as much as possible and the circuit can be easily and inexpensively changed. Is an issue.

[0008]

In order to solve the above problems, according to the present invention, a power supply side circuit upstream of a fuse is formed by a bus bar stamped into a circuit shape, while a load side circuit downstream of the fuse is an insulating plate. The conductors laminated above and below are wired in parallel in the same layer and are wired in the orthogonal direction through the insulating plate, and the conductors in the upper and lower layers are single core wires made of only conductors, or single core wires and strips. It consists of a bus bar with a shape, and the upper and lower conductors are welded and connected through the openings provided in the insulating plate at the required intersections, and a circuit of the required shape is formed from these conductors arranged in a matrix. , The terminal of the fuse is inserted and connected to the terminal press-fitting groove of the pressure-welding terminal or the terminal press-fitting groove formed on the bus bar, which is pressure-connected to the single-core wire. The connection with the circuit is characterized in that the tab provided on the pressure contact terminal pressure-connected to the single core wire or the tab of the bus bar is projected to the connector accommodating portion formed on the outer surface of the housing of the electric connection box. Offering a box. That is, in the load side circuit downstream of the fuse, the conductor is arranged in the X direction on the upper surface via the insulating plate,
A conductor is arranged on the lower surface in the Y direction and welded through an opening of an insulating plate at a required intersection to form a circuit.

[0009]

As described above, the power supply circuit on the upstream side of the fuse has the same vehicle grade, that is, the circuit shared by each group of high-class vehicles, middle-class vehicles, and low-grade vehicles is formed by a mold and has a dedicated shape. And has versatility. In the power supply circuit on the upstream side of the fuse, most of the common circuits have the same vehicle grade, and therefore the busbar is rarely changed according to the vehicle type.
When the circuit is changed, the bus bar corresponding to the circuit is welded to the shared bus bar to cope with the change.

On the other hand, the circuit on the load side downstream of the fuse is often changed according to the vehicle type, and may be changed according to the grade even in the same vehicle type. , A circuit is formed by connecting at required intersections. According to this method, the circuit can be easily changed only by changing the position of the connecting intersection.

Specifically, for example, the conductors wired in the X direction and the Y direction are single-core wires made of only the conductors, and are inserted into wiring grooves in the X direction and the Y direction formed on both front and back surfaces of the insulating plate. The upper and lower single-core wires by welding through the opening formed in the bottom surface of the wiring groove, and the pressure-contact terminals are pressure-connected to the required locations of the single-core wire. The tab provided at the end is projected into the connector accommodating portion formed on the outer surface of the housing of the electric junction box, and the other pressure contact terminals are connected by inserting the fuse terminals into the terminal press-fitting grooves provided at the other end.

By connecting the pressure contact terminal to the single core wire as described above, the external circuit can be connected from a desired position, and the fuse can be easily connected by using the pressure contact terminal. it can.

The load-side circuit downstream of the fuse is composed of a single-core wire made of only a conductor and a strip-shaped bus bar,
The single core wire is inserted into the wiring groove provided in parallel with the insulating plate for wiring, and the bus bar is arranged in parallel on the upper surface of the insulating plate in a direction orthogonal to the single core wire to form the single core wire and the bus bar. Arranged in a matrix, provided a protruding portion bent downward at a required portion of the busbar, and connecting the protruding portion by resistance welding at an intersection with a single core wire, or on a side surface of a required portion of the busbar. The bending portion provided with the press contact slot may be provided downward and the press contact slot may be press contacted to the single core wire. That is, the load side circuit downstream of the fuse is
A single core wire is inserted into the groove on the same side of the insulating plate and wired in the X direction, and a bus bar is wired in the Y direction on the surface of the insulating plate above the groove, and welding or pressure contact connection is made at the intersection to form a circuit. Is formed.

That is, instead of arranging the single-core wires in a matrix, a matrix is formed from the single-core wires and the bus bars, and the circuits are formed by connecting at desired intersections. In this case, as in the case of the single core wires, the circuit can be easily changed only by changing the position of the connecting intersection. In addition, since a strip-shaped fixed shape is used as the bus bar, it is possible to achieve a significant cost reduction compared to a bus bar formed by punching into a dedicated shape with a mold, and shortening the number of production days. Can be achieved.

[0016]

[0017]

The load side circuit is formed into a strip shape, the bus bars are arranged in matrix in the X and Y directions with an insulating plate interposed, and the bus bars are welded to each other through the openings formed in the insulating plate at the intersections. It goes without saying that it is okay.

A connector having a joint connector function is fitted in the connector accommodating portion formed on the outer surface of the housing, and the connector constitutes a branch circuit.

Specifically, the connector to be fitted in the connector accommodating portion has a structure in which split connectors are laminated and integrated, and each of the split connectors is provided with a terminal accommodating chamber in a horizontal row, and an electric wire of a wire harness is provided. A male / female terminal for inserting a terminal to be connected to a terminal into the terminal accommodating chamber, and for connecting a terminal portion to be fitted and connected to a load side circuit in the housing and terminals in vertically divided split connectors to each other in the terminal And a section.

Further, it is preferable that at least a part of the terminals to be inserted into the terminal accommodating chambers in the horizontal row be a chain-like terminal, and a required number of terminals be continuous through a continuous plate portion.

As described above, when the connector to be connected to the electrical junction box is made to have the function of a joint connector and the branch circuit is formed by the connector, the branch circuit incorporated inside the electrical junction box is provided. Can be provided on the connector side. Therefore, it is possible to reduce the internal circuit of the electrical junction box. Therefore, if the required number of circuits is the same as the conventional one, it is possible to suppress the increase in the internal circuit density. It is possible to provide various circuits.

The connectors fitted to the connector accommodating portion are attached to each wire harness such as an instrument panel harness, a floor harness and a roof harness. Also,
When a connector is connected to each wire harness, the circuits connected to these wire harnesses are connected to each fuse via a matrix circuit.
