The invention relates to the development of a plug coupling according to patent 1 130 882, its coupling halves in each case a serrated crown located outside the range of the high-frequency oscillations have, the crowns being pushed into one another during coupling.

According to the main patent, it is a coupling device for coaxial lines, consisting of two Coupling halves that can be pushed into one another, formed by crowns provided on both coupling halves are secured against relative rotation in a nested position, the crowns are already known to form on one coupling part as lateral projections and this coupling half in the other To make the coupling half insertable in such a way that the place at which the crowns of the two coupling halves engage in one another is outside the area the high frequency vibrations. The crowns are firmly attached to the coupling halves tied together. It has now been shown in practice that this type of anti-twist protection is also the real one Coupling of the coupling halves is made easier, especially with plug couplings in which each coupling half an outer conductor section with a flat end face and one on this outer conductor section Has loosely rotatable union nut, the flat outer conductor end faces for coupling laid flat on top of each other and the union nut of one coupling half with a corresponding one Thread on the outer conductor section of the other coupling half with application an axial pressing force on the two outer conductor end faces is screwed. The crowns act here as centering elements and make it easier the exact axial merging of the two coupling halves. But now it is further away It was found that in many cases such a protection against rotation is not necessarily useful and should be switched off if necessary.

In a further development of a plug coupling according to the main patent, it is therefore proposed according to the invention, to let the crowns rotate in each coupling half and one on each coupling half to provide known locking device, through which the crown against relative rotation in can be secured with respect to the coupling half.

Locking devices are also available in a wide variety of embodiments for cable plug-in devices and the like already known. The inventive use of such a known per se Locking device for the crowns of the coupling halves of a plug coupling after the main plug coupling for coaxial lines

patent is achieved that the plug coupling either with or without anti-twist protection Anti-twist protection is applicable. When the locking device is released, the then omitted rotatable crown protects against twisting, but the advantageous properties of this crown remain as a centering element to facilitate an exact axial merging of the two coupling halves.

This is particularly advantageous in the case of plug couplings in which each coupling half has an outer conductor section with a flat end face and one loosely rotatable on this outer conductor section having arranged union nut, wherein for coupling two such coupling halves flat outer conductor end faces are laid flat on top of one another and the union nut of the one Coupling half with a corresponding thread on the outer conductor section of the other coupling halves is screwed. In this case, according to a development of the invention, it has proven to be Proven to be advantageous if the crowns are each in the end wall of the outer conductor section of each coupling half are embedded and the locking device by at least two in an annular groove on Outer conductor section insertable half rings are formed with axially projecting lugs, the lugs these half rings in one insertion position in corresponding recesses of the crown and the Engage outer conductor section and thus this crown on the outer conductor section without twisting

set and in the other insertion position are out of engagement with these recesses, so that the crown is freely rotatable on the outer conductor section. The outer conductor section can consist of two torsion-proof assembled sleeve parts exist, and the ring groove receiving the half rings can be formed on the circumference of the inner sleeve part and that normally via the inner sleeve part and the outer sleeve part engaging the annular groove can be used to remove the half-rings or their Change of position relative to the inner sleeve part can be axially displaced. After all, it turned out to be Proven to be useful when the outer sleeve part is in the normal position by a screwed-on ring is held axially.

The invention is illustrated below with reference to schematic drawings of an exemplary embodiment explained in more detail.

F i g. 1 shows a coupling half according to the invention in cross section, namely the section of FIG the left half of the image is drawn offset by 90 ° compared to the section of the right half of the image;

F i g. 2 shows an exemplary embodiment for an inventive Locking device.

The coaxial connector half shown in Fig. 1 consists of an outer conductor section 1 with a flat one End face 2 and a nut 3 loosely rotatably arranged thereon, which has a rear Flange section 4 finds a stop when it is axially displaced forward. At the front front end 'of the union nut 3 is a thread 5 is provided with a corresponding Thread 6 on the circumference of the outer conductor section 1 can interact. For coupling two such identically designed coupling halves, the end faces 2 are placed flat on top of each other, and one of the union nuts 3 is connected to the thread 6 of the other coupling part (its union nut is pushed back all the way). As a result, the end faces placed on top of one another are firmly pressed against one another and good electrical contact is achieved.

According to the invention is now to facilitate the exact concentric merging of the two Coupling halves and for optional anti-twist coupling of the two halves in the End face 2 of the outer conductor section 1, a centering crown 10 let in rotatably. The prongs of this Crown 10 are designed and protrude beyond the surface of the end face 2 such that the axial Merging two coupling halves the crown teeth interlock and form a secure centered mutual support of the two end faces lead. The outer conductor section 1 consists preferably made up of two sleeve-like parts 11 and 12 which are plugged into one another and in which FIG. 1 normal position shown by a suitable measure, e.g. B. a hexagon fit, against rotation are secured. In the annular gap remaining between the two parts and 12 is the Crown 10 inserted.

On the lower sleeve-shaped section of the crown 10, a flange 13 is formed which is provided with two diametrically opposite recesses 14. The crown 10 rests with its flange 13 ⁶ S on a flange-like shoulder 15 of the inner sleeve part 11, and on this flange shoulder 15, as in the case of the flange 13, recesses 16 corresponding to the crown are provided diametrically opposite one another. In addition, an annular groove 17 is formed on the circumference of the sleeve part 11, in which two half-rings 18 and 19 (FIG. 2) are inserted. These half rings 18 and 19 each have a nose 20. The half rings can be inserted into the annular groove that the noses 20 engage in the corresponding diametrically opposite recesses 14 and 16 of the crown flange 13 and the flange 15 and thus the crown with respect to secure the sleeve part 11 against relative rotation. The half-rings 15 and 19, of which only one can optionally be provided, can, however, also be inserted in such a way that the lugs 20 come to lie to the rear in corresponding recesses 21 of the sleeve part 11, as shown in FIG. 1 is indicated by dashed lines. The crown can thus be freely rotated relative to the sleeve part 11.

The optional insertion of the half-rings in one or the other position is made possible by pushing back the outer sleeve part 12. For this purpose, a ring 23 is screwed onto the upper end of the sleeve part 12, by means of which the sleeve part 12 is axially held in the normal position shown and the crown 10 is prevented from falling out of the annular gap between the two sleeve parts. After releasing this ring 23, the crown 10 can be removed and, after the sleeve part 12 has been pushed back accordingly, the half-rings 18 and 19 that are exposed therewith can be turned around in the annular groove or possibly removed entirely .
