Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an interconnection device for an automobile wiring harness that facilitates its manufacture.

As is well known, the electrical components and circuits of an automobile are divided into blocks such as the front, rear, and instrument blocks from a battery as a power source via a fuse, with various switches etc. interposed between them. However, in the past, branch connections for a large number of electric wires were made at a number of separation points depending on the location of the electrical components, and as a result, the work of stripping, connecting, taping, etc. of the electric wires was diverse and extremely complicated. It was impossible to mechanize the manufacturing process, which was a bottleneck to mass production.

The present invention was made with attention to the above points,
The wiring harness is divided into power circuit, front circuit, rear circuit, instrument circuit, etc., and each circuit is converged with a connector and connected to the opposite connector of the branch connection device, and the circuits are interconnected. The interconnection device is designed to be centrally wired within the device, and is intended to facilitate the fabrication of such an interconnection device and mass-produce it by machine.

The present invention will be described below with reference to the drawings. Reference numeral 1 indicates a main body case of an interconnection device, and upper and lower case parts 1a.

1b and left and right case parts IC, ld are formed in series from a synthetic resin material with hinge characteristics, and a connector housing 2 or a fuse box 3 is integrally formed with these case parts.

The connector housing 2 has a support hole 2a for a terminal fitting, and the fuse box 3 has a support hole 3a for a fuse holder.

When assembling, first, a terminal fitting or a fuse holder terminal is attached to the support holes 2a, 3a of the main body case 1 in the unfolded state as shown in FIG. 2.3.

Figure 4 shows the case of a relatively large current circuit, and the terminal fitting 4
A case is shown in which the electric wires 6 are crimped and connected to the fuse holder 5 in advance and then installed in their support holes 2a3a.

FIG. 5 shows a case where the terminal fitting 7 is attached to the support hole 2a, wrapping 8 is applied, and the electric wire is connected.

FIG. 6 shows a case where a flexible printed board 10 is disposed while the terminal fitting 9 is installed in the support hole 2a, and the terminal fitting 9 and a predetermined printed circuit are connected by soldering.

In any of the above embodiments, terminals are attached in advance to the housing or box portion of the main body case 1 in the unfolded state, and a connection circuit is formed between them.

From this state, each case part 1a, via the hinge part 1e,
1b, IC, 1d, and insert the protrusion 1b1 into the hole 1a.
1 to maintain the folded state.

Although the present invention is constructed as described above, terminal fittings can be inserted into the connector housing portions of the plurality of case portions all at once from the same side when the plurality of case portions are in the unfolded state. The connection work between the metal fittings can be easily performed, and from this state, it is possible to immediately assemble each case part by folding it through the hinge part, and the manufacturing and assembly process of the entire connecting device is easy. can be greatly simplified.

Further, in the present invention, it is possible to unfold the case while maintaining electrical connection between the cases, which is extremely convenient for troubleshooting and repair.
