Rudolf Tesch in Berlin-Wilmersdorf. Junction and junction box.

Addendum to patent 351336.

Patented in the German Empire on February 27, 1924. Longest duration: March 11, 1937.

The invention relates to a junction and junction box with junction boxes straight connecting rails.

According to patent 351336, the rails are in the altitude offset from each other.

The invention achieves the same purpose with simpler means and a more durable one Design of the porcelain body in that the height differences in the connecting rails obtained by crossing each other.

In the drawing, an embodiment of the invention is shown, namely shows:

Fig. Ι an elevation of the box with an openwork lid,

Fig. 2 is a side elevation of the can with the openwork lid,

Fig. 3 is a plan of the box with an openwork lid, ao

Fig. 4 a section according to AB in Fig. 3 without the cover.

Fig. 5 shows a connection rail and Fig. 6 the cover in view.

The box consists of an insulating housing ι and a round cover 7, which can be made of metal or insulating material and is provided with marked pipe entries 2.

In the upwardly open channels 3 of the insulating housing 1 are straight connecting rails 4 stored.

The connecting rails are parallel to one another in plan and crossed in elevation and side by side in the side view. They are separated by an insulating bar 18.

The connecting lines directed transversely to the longitudinal axis of the connecting rails can be fed in a straight line and brought directly into connection with the associated connecting rail (Fig. ι, 3 and 4).

The cutouts 8 of the insulating web 18 are used for the higher ends of the connecting rails, to connect cross lines. The cutouts 16 in the outer wall the clamp are in a straight line to the cutouts 8 above .dem deeper End of the other connecting rail (Fig. I, 3 and 4).

The deeper cutout 17 in the outer wall of the can is used to introduce the Cross line into the lower-lying connection rail (Fig. I, 3 and 4).

The fastening screw goes through the cover and through the hole 13, which is shown in a tubular raised approach is arranged so that the lid does not become live Sharing comes into contact.

As a result of the crossing of the connecting rails, a cross line can be made via cutout 16 and 8 to the next but one connecting rail, because the end in question higher than the next connection rail.

Due to this arrangement of the connecting rails, only open cutouts are available Cable routing required, which at the same time also provides a better overview for fastening same result. This also makes the clamp into a symmetrical body.

The box can also be used concealed because the wires are attached to the Connection rails do not have to be carried out under these.

The wide insulating web 18 takes two auxiliary clamps in the middle on both sides 5 (Fig. 2 and 3), which have the purpose of using different line material to connect to each other, e.g. B. Lines, laid in insulating tube, to be connected with tubular wire.
