Description

DETAILED DESCRIPTION OF THE INVENTION (1) Object of the invention (industrial application field) The present invention provides for each branch circuit in a wiring harness used for internal wiring of an automobile etc. to be punched out of a conductive metal plate and patterned. replaced with a strip-shaped branch conductive path,
Each of these branch conductive paths is accommodated in an insulating case provided with an attachment port for a connector, etc. formed at the terminal of the fuse, relay, and 7-ring harness.
A wiring harness interconnection device and assembly thereof, in which each branch circuit in the wiring harness is centrally wired in an insulating case by connecting the connector to each of the J paths through the mounting port. Regarding the method.

(Prior art) As shown in Fig. 2, this type of conventional interconnection device has a conductive metal plate placed inside an insulating case (C) consisting of a lower case (a) and an upper case (b). After being punched out and patterned, a group of strip-shaped branch conductive paths (e
) and a thin insulating plate (f) formed by laying these branch conductive path groups (e) are housed in appropriate combinations of several layers,
Lower case (a) and or upper case (b)
is provided with mounting ports (g) (g)' for fuses, relays, wiring harness connectors, etc.

Note that the branch conductive path group located at the bottom layer is located in the lower case (
a) may also be installed.

The branch conductive path group (e) laid on each of the insulating plates (f)
) Each branch conductive path (el) (el)' is formed by one insulating plate m
On the other hand, a plate formed by simultaneously punching a -m conductive metal plate using a mold on the - side is used.

In assembling this type of interconnection device, the group of branch conductive paths (8) punched and bent from a single layer of conductive metal plate is transferred to a single insulating plate without changing its pattern. A method of fixing it to the insulating plate is adopted, and if each branch conductive path group taken from a two-layer conductive metal plate is transferred to a single insulating plate, the number of steps required for the above assembly method will be doubled. This is because two molds for punching the conductive metal plate are required.

On the other hand, the terminal that becomes the terminal part of each branch conductive path stands up in the direction perpendicular to the direction in which each branch conductive path ((31)((!1)') is patterned, that is, the direction in which the branch conductive path is routed. A perforation (h) is formed in the insulating plate (f) located in the direction in which the terminal portion (d) rises.

In addition, there are branch conductive paths (el) interposed between the insulating plates (f).
)(el)' is connected to the lower case (a) or the upper case (
b), and the mounting openings (o) (g) formed in that part.
)',,,, is coming.

(Problems to be Solved by the Invention) By the way, in the wiring harness interconnection device configured as described above, each of the terminal portions extending from the two branch conductive paths with respect to the above-mentioned mounting hole has a flat surface that is When faced with each other, punching out the two branch conductive paths from a single conductive metal plate can be understood by assuming the state of the branch conductors before the bending process. This was impossible because the portion that would become the terminal would polymerize under such conditions.

Therefore, in order to combine two branch conductive paths so that the plane part set 1j of the terminal part faces each other, it is necessary to punch and bend a 1 m branch path from each of two different conductive metal plates. , each of these branch conductive paths is laid on two different insulating plates ([) as shown in FIG. 3, and when stacking the insulating plates (f) with the branch conductive paths (el) sandwiched between them, The terminal part (d) of one branch conductive path located in the lower layer is inserted into the perforation (h) of the insulating plate located above the other conductive path, and the flat part of the terminal part (d) is inserted. A method of confronting each other is adopted.

From the above, in order to assemble the conventional wiring harness interconnection device of this type, in order to minimize the number of molds required to punch out the branch conductive paths from the 1[f-grade metal plate, In order to minimize the number of man-hours required for the process of fixing these branch conductive paths to the insulating plate, it is desirable to form the branch conductive paths housed within the insulating case from conductive metal with as few layers as possible. However, the pair of branch conductive paths that are assembled so that the flat surfaces of the terminals face each other facing the mounting openings of relays, fuses, wiring harness terminal connectors, etc. formed on the insulating case are made of two layers. It is irrational that the conductive metal plates must be formed separately, and the number of layers of conductive metal plates must be increased for this purpose.

(2) Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned unreasonableness, the present invention provides at least two terminals that are installed vertically so that the flat parts of the terminals face each other facing the mounting opening. In the part of a set of branch 1B electric circuits that is in contact with one or both insulating plates, that is, in the part routed on the insulating plate,
It was decided to perform a bending process.

(Function) By doing this, the position of the terminal section that stands perpendicularly to the routing section of the branch conductive path is moved toward the section that has been bent by the bending allowance of the routing section. From a 1m metal plate of -m, with a mold on the - side,
Each of the above-mentioned sets of branch conductive paths can be formed by handling.

(Example) Figures 1 (a) and 1 (c) are perspective views showing the process of forming a branch l electric path from a single layer of conductive metal plates so that the flat parts of the terminal parts face each other. be.

First, branch conductive paths (1), (2), (3), and (4) are simultaneously punched out from one layer of conductive metal plate (not shown) using a mold on the negative side, and these branch conductive paths (1) ( 2)(3)(4)
Terminal forming elements (1a) (4a) (3a) (4a) and routing portions (1b) (2b) (3bH4b) are configured,

[See Figure 1 (A)] Next, each of the terminal forming elements (1aH2a) (3a) (4a) of the four branch conductive paths (1) (2) (3H4)) is replaced with a routing portion (1b) ( 2bH3bH4b) is installed vertically to the routing direction of the terminal part (IA) (2A)t.
3A) (4A) [see Figure 1 (b)] After that, each routing section (1b
) (4b), bend the parts (1x) and (4x), and bend the entire area from the said part to the terminal part in the direction of arrow 1 (Y)m shown in Figure 1 (b) by the bending allowance. and move the standing positions of the terminal parts (1A) and (4A) to a place where their flat parts face the flat parts of the terminal parts (2^) and (3^). [Refer to Figure 1 (C)] Although not shown, the terminal parts where the flat parts face each other can be inserted into the installation openings for fuses, relays, connectors, etc. when the wiring harness interconnection device is assembled. become.

In the present invention, at least one set of branch conductive paths formed by the above steps is included in the interconnection device.

(3) Effects of the invention In the present invention, which provides a wiring harness interconnection device having the above-described assembly method and structure,

It is possible to reduce the number of molds for assembly and reduce the number of assembly steps.
