Description

[Detailed explanation of the idea] The present invention relates to an improvement of a branch junction box.

A large number of electrical parts are used in electrical equipment and automobiles with complex circuit elements, and information between these electrical parts,
BACKGROUND OF THE INVENTION In order to complete an electric circuit for transmitting and receiving signals or electric power, assembled wires, generally called "no-nes", are used.

However, because the installation positions of electrical components are often dispersed in various locations, one set of wires requires many branch wires, which requires time and effort to manufacture. A wiring method has been proposed in which parallel electric wires without branching portions are connected from the junction box by organizing the conductive patterns in a box.

A typical electrical junction box having this branch line circuit therein has a plurality of bus bars (circuit conductors) i, i', i with conductive patterns as shown in FIGS. 1 and 3.
' etc. are laminated and housed in the casing 2, and the end E of the bus bar, which is an element of the conductive pattern, is exposed from the casing and used as the connector terminal 4.

In Figures 1 and 3, 5 is an insulating partition plate, 6 is a terminal hole, and 7 is an insulating partition plate.
(d fuse holder, 8 relay holder, 9, 91[-
7 connector and 13 indicate an insulated wire.

In this type of branch junction box, the prying prevention wall 10 (wall that prevents prying with a mating coupler) of the connector 9, in which the end E of the bus bar is exposed from the casing 2 and is used as the connector terminal 4, is conventional. As shown in Fig. 1, the walls erected on the short side and the long side are of a rectangular box shape with the same height.

With such a shape, internal warping of the wall is likely to occur during molding.

The present invention has been devised in view of these points, and is intended to eliminate the above-mentioned drawbacks and also provide other effects.

The present invention will be explained below with reference to illustrative FIGS. 2 and 3.

FIG. 2 is an external view of the branch junction box of the present invention, and conventionally, one or more bus bars roughly attached to an insulating plate as shown in FIG. 3 are housed in the case 2 of FIG. It's no different.

The same reference numerals as in FIG. 1 in FIG. 2 above indicate the same parts.

The branch junction box of the present invention is generally the same as the conventional one, but the difference is that the connector prying prevention wall 10 has been specially devised.

That is, in the present invention, the walls A and A', in which the prying prevention wall 10 of the connector is erected on the short side, are rectangular as before, but the wall B, B, which is erected on the long side, has a part in the center of the upper end. The cutout 11 is made into a substantially U-shape.

The present invention, in which the wall erected on the long side is substantially U-shaped, has the following advantages.

[F] Compared to a system with walls of equal height around the entire circumference, the wall height is small, especially on the long side walls, which reduces water bed defects due to internal warping.

■ The wall height is reduced by one part and the missing part of the wall is placed especially on the long side, which saves materials.■ The wall height is reduced by one part and the missing part of the wall is provided especially on the long side. Since it is installed on a wall, the wire side connector can be easily removed.
