Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an insulating box in a wiring harness interconnection device for centrally wiring a large number of branch circuits in the internal wiring of an automobile.

In recent years, the addition of functional parts to automobiles has spurred the development of interconnection devices that employ centralized wiring methods, such as busper wiring methods and printed wiring methods, to efficiently route wiring within a limited space. I'm putting it on.

More specifically, the present invention relates to an insulating box used in an interconnection device, which will be described later, obtained as a result of the above development.

As shown in Fig. 1, an interconnection device in which the insulating box of the present invention is adopted is a system in which linearly formed conductive members a are arranged side by side to connect electrical components that are separated by the same type of system or by the direction of the wiring position. Wire harness b1, c1, d1, d2, d3, e1, e2 from
. . . j1, j2, j3, j4, j5 are connected to the conductive member a for each block B, C, D, E…J at a position on a line in the direction in which the conductive members a are mutually adjacent, and the wires Harness b1, d1, f

. . . f9 and j5 are connected or branched to each other.

An example of implementing the present invention will be explained below based on the drawings.

In this example, as shown in FIG. 2, the above-mentioned linear conductive member a is strip-shaped,
The conductive members a are arranged in parallel with their plane parts facing each other, and wire harnesses b1, c1...j to the conductive members a are provided.
1, j2, j3, j4, and j5 are connected by fitting an electrical connector l having a clamping part k attached to a wire harness terminal into the conductive member a from the width direction A. I will explain using an example,
The interconnection device in which the insulating box of the present invention is used is not limited to the configuration described above.

3, FIG. 4, FIG. 5, and FIG. 6, 1 is an insulating box that accommodates a linear strip-shaped conductive member a; passages 2, 2'... for accommodating them with their planar parts facing each other and arranged side by side.
It has connector fitting parts 3b, 3 inside.

Part of it is configured within h, 4i, and 4j.

The above-mentioned passages 2, 2'... are always open in at least one of the upper and lower surfaces 3, 4 over their entire length in the insertion direction, and have through holes 10 in addition to the connector fitting hole 9. It is open to the outside.

The through holes 10 and the connector fitting holes 9 alternately pass through the passages 2, 2', . . . from the opposing upper and lower surfaces 3, 4 through the passages 2, 2', .

That is, based on FIG. 5, the aspects of the through hole 10 and the connector fitting hole 9 related to the passages 2, 2', etc. will be explained based on each case.
When the connector fitting portions 3d and 3f are adjacent to each other on the top, a through hole 10 is formed between the bottom surface and the bottom wall of each connector fitting hole 9 so as to pass through the passages 2, 2'... . On the other hand, when the connector fitting parts 3c and 4i face diagonally backward through the passages 2 and 2', the bottom surface of the connector fitting part 3c and the part of the frame wall 8 of the connector fitting part 4i between the base end of the side surface 8a located near the bottom surface, and between the bottom surface of the connector fitting portion 4i and the portion of the frame wall 8 of the connector fitting portion 3c and the side wall 8a base located near the bottom wall. A through hole 10 is formed between each end.

Further, between the insertion opening 7 of the strip-shaped conductive member a and the connector fitting part 4i near the insertion opening 7, a through hole 10 cut from the insertion opening 7 to the bottom of the connector fitting part 4i is formed on the surface 4. is formed.

As described above, the four through holes are opened by the protrusions 15-1, 15-2, 15-3, and 15-4 provided on the integral molding molds 13 and 14 shown in FIG. Also, a portion of the inner surface of the passages 2, 2' is formed by the end surfaces of these projections.

In addition, the inner surfaces of the connector fitting hole 9 and the through hole 10 penetrating the passages 2, 2', 2''... and the passages 2, 2', 2''...
The corner formed by the inner surface of 2'' and located on the insertion opening 7 side of the strip-shaped conductive member a is cut off to form a tapered portion 12, 12'. The tapered portions 12, 12', . . . serve to guide the strip-shaped conductive member a into the passages 2, 2', 2'', .

Note that the strip-shaped conductive member a is installed inside the insulating box 1 in accordance with the wiring diagram shown in FIG. Wire harness b1, c1...
Each block B of j1, j2, j3, j4, j5,
C...J are provided at locations corresponding to the connection points to the strip-shaped conductive member a, and the wire harness terminals are connected to the strip-shaped conductive member a at The electrical connector l has a clamping part k that can be fitted from the width direction, and the electrical connector l has connector fitting parts 3b, 3c, 3d, 3e, 3 as shown in FIG.
Connector fitting parts 3b, 3c, 3d, 3 in the connector 11 fitted to connectors f, 3g, 3h, 4i, 4j
They are guided into e, 3f, 3g, 3h, 4i, and 4j.

As described above, in the present invention, the passages 2, 2', .
Through-holes 10 or connector fitting holes 9 passing through the upper and lower surfaces 3 and 4 facing each other face each other through..., and the passages 2, 2'... At least one of the passages 2, 2', .
Therefore, the insulating box 1 of the present invention can be integrally molded by clamping the molds 13 and 14 from above and below, as shown in FIG. 10, and a slide mold can be used. Therefore, the passages 2, 2' can be formed. Further, the work of housing the strip-shaped conductive member a inside is also carried out by moving the strip-shaped conductive member a from the insertion opening 7 to the passages 2, 2', . . .
Since it only needs to be inserted into the interior, its production is extremely simple.

On the other hand, FIGS. 7 and 8 show another embodiment in which the fitting holes 9 of the connector fitting portions formed on the upper and lower surfaces 3 and 4 are partially doubled in the vertical direction in FIG. The bottom surface of the connector fitting hole 9 is formed in a part of the lower region of the connector fitting hole 9.

In the present invention, it is also possible to use a structure in which strip-shaped conductive members are connected to each other at their ends as shown in FIG.

The present invention has been explained in detail above based on the embodiments, but to explain it further, a connector is provided across the axial direction of the passage on each of the upper and lower surfaces on both sides in the width direction that supports the conductive member housed in the insulating box. By providing the fitting holes or through holes alternately, it is possible to cut out the mold in the width direction of the conductive member when integrally molding the insulating box, and thus it is possible to cut out the mold in the width direction of the conductive member, which is conventionally difficult to form, for example, to form the passages. In place of the insulating box, which was composed of two storage cases separated into upper and lower parts, it was possible to produce an insulating box extremely easily and inexpensively.
