Recesses of the parts introduced wire coils

Patented in the German Empire on December 8, 1935

The invention relates to a holding member for parts to be resiliently connected to one another, especially with metal vapor converters. It has already been suggested to be resilient Connection in electrical discharge apparatus, namely for resilient connection of internal parts of electrical discharge devices, to use wire coils, which one threads into corresponding recesses of the parts to be connected to one another. These methods of attachment have the disadvantage that the wire coils during operation, especially in the case of discharge equipment, that are exposed to vibrations, e.g. B. on vehicles to hike begin, which affects the security of the attachment. About the wandering of the wire coils to prevent, it has already been proposed to use wire coils with differently wound To use turns. By friction the wound in the opposite sense Windings on the walls of the recesses (grooves) intended to receive the wire coils were achieved that the wire coils were relatively fixed. In the case of electrical discharge apparatus, in where high temperatures occur during operation, it turns out, however, that these means for fixing the wire coils are often insufficient, since the wire coils loosen also here in the case of thermal expansion of the parts surrounding them.

According to the present invention, the difficulties mentioned are avoided and the wandering of the wire coils is excluded if the one to accommodate the wire coils certain, partly delimited by grooves designed spaces so that they have a substantially non-circular cross-section, the approaches, for example, the .Form of an ellipse, and in those having such a cross-section Recesses the wire coils introduces under pressure in such a way that the individual turns have a pressed inclined position take in. Here, too, the turns +5 can sometimes be twisted in the opposite direction be. You can also use a second coil piece as the final piece, its turns are also tilted in the opposite direction.

Some exemplary embodiments are shown in the drawing.

Fig. Ι shows a plan view of two together parts to be connected,

Fig. 2 shows a cross section through Fig. 1 along the line H-II.

Fig. 3 shows another embodiment in cross section.

According to Fig. 1, part 2 becomes part 1 by means of the intermediate link 3 resiliently

bound. The intermediate member 3 consists of two wire coils 4 and 5, which assume inclined positions in different directions within the recesses 6 and 7. Instead of two wire coils 4 and 5, a single wire coil can also dwell ¹ , the one in which some of the coils can assume an opposite inclination. The wire coils are introduced from the outside into the recesses 6 and 7 under pressure in such a way that the individual turns are inclined.

In the embodiment according to FIGS. 1 and 2 , the inclined turns have a substantially horizontal position, while according to the embodiment according to FIG. 3 they are arranged substantially vertically.

The new intermediate link is suitable for use on electrical discharge devices, For example, with large mercury vapor rectifiers, not only for the resilient fastening of parts such as anode grids, Electrodes, protective tubes, cooling fixtures or the like, but also for storing the converter vessels even, especially when used on mobile systems, mobile converter stations, vehicle converters and the like. It does not need any special reference that the choice of material of the intermediate pieces the special conditions must be adjusted.
