The present innovation relates to a collar socket in a round design from one. Can upper part, a "can lower part and a can insert which is fastened with the aid of screws on a bearing block arranged in the can lower part.

The ... construction of the new socket should be used for sockets of different voltages, different numbers of poles, different frequencies and different currents. While the sizes of the sockets and the contact parts according to the maximum permissible amperage is different, the size remains the same for the different voltages and errors, as well. the size of the contact parts .'-. determined for different voltages Doses differed / only in the position of the Can insert that receives the contact parts. This is . namely arranged so that the Brdleiterhülse at a Tension of 580 yoIt. at 6 o'clock, "at 500 YoIt at .7 o'clock and at 750 YoIt to .5 h etc. - The new collar socket is designed in such a way that they are suitable for all possible operating voltages

gen can be used. This goal is achieved in that in a collar socket of the type described above, an annular bearing block is provided in which several G-thread bushes are arranged for screwing on the socket insert, and which allows the socket insert to be rotated and fastened in any desired angular position.

The bearing block is designed so that there is enough free space between it and the top part of the box to allow it to pass through of the connection lines remains.

It has also proven to be particularly advantageous, the dividing joint between the top and bottom of the can not to run above the armored thread as was customary up to now, but to be arranged at the height of the armored thread /. The box is divided significantly lower and has the advantage that the contact body on the Connection side is easily accessible from all sides. However, the armor thread is not cut by the partition joint, but taken up by an annular part belonging to the lower part of the box. To the armor thread a bigger one To give strength, the upper half of the ring-shaped part is provided with a groove in which a corresponding

Web of the can top engages. The armored thread bushing is therefore additionally supported by the socket top.

To further explain the novelty, like the figures serve.

Figure 1 shows a plan view of the. Can lower part.

FIG. 2 shows a section through the lower part of the can "lengthways the section line AB.

Figure 3 shows a front view of the can bottom.

FIG. 4 shows a longitudinal section through the lower part of the can the section line EE.

Figure 5 shows a plan view of the can top.

Figure 6 shows a front view of the can top.

FIG. 7 shows a longitudinal section through the upper part of the can the cutting line CD.

FIG. 8 shows a section through the entire can, consisting of the upper part of the can, the lower part of the can and the can insert.

Figures 1, 2 and 3 clearly show that the can lower part 1 is provided with a bearing block 3 in which Threaded sockets 4 for fastening the can insert 5 are arranged around the circumference. The arrangement is made that a twisting of the can insert 5 and fastening is possible in any angular position.

As can be seen in particular from FIGS. 2 and 8, the dividing line is between can bottom 1 and can top 2

_r middle

very low, about at the level of the armored thread ^ '6. The armor thread 6 is not cut by the dividing joint, but is in an annular shape Part 7 of the lower part 1 of the can was added. To the ring-shaped Part 7 and thus the armored thread 6 sufficient mechanical strength, especially against tensile stress to give, a groove 8 is provided in the upper half of the annular part 7, in which a corresponding Web 9 of the can upper part 2 can intervene, like that can be seen in FIG.

As shown in FIGS. 5, 6 and 7 in particular, the new one Can provided with a closed can collar 10. Such a closed can collar has the advantage that a incorrect insertion of the plug is practically impossible. Sole marriage closed can collars are known per se, In many cases, however, lan has hesitated to take advantage of the associated advantages because of the previously known can designs this was always associated with a relatively small cover and thus poor connection possibilities. Around To circumvent this, longitudinally divided cans were then used. Such eyelets have a convenient connection option,

however, the split collar present there may be a wrong one Do not prevent the plug from being inserted in any case, especially if the socket ends "The screws used are loose. The new socket connects the advantages of cans with an undivided collar with the easy connection of cans that are split lengthways, without having to accept the respective disadvantages.

Can lower part 1 and can upper part 2 are connected to one another by screws. For this purpose, there are two in the lower part of the box 1 or several G-thread bushings 11 are provided. In order to facilitate assembly, as can be clearly seen in FIG Can lower part 1 provided over the threaded bushes 11 conical guide bushings 12, the one dropping avoid the screws and should also allow easy assembly.

The new collar connector can for different voltages and in a correspondingly changed size for different Find currents, especially for currents between 16 and 200 amps, use. Can top and bottom can, for example, be made of plastic or metal, e.g. die-cast aluminum.
