DETAILED DESCRIPTION
[0038] The figures contain partially simplified, schematic representations. In part, identical reference signs are used for like, but possibly not identical elements. Different views of like elements may be scaled differently.
[0039] Directional indications such as “top”, “bottom”, “left”, “right”, “front” and “back” refer to the various representations and may vary in respect of the elements shown.
[0040] FIG. 1 shows the plug-in region of a round plug connector 1 according to the invention, wherein the round plug connector 1 has at least two housing elements 2 and 2′. Here, the housing element 2 receives an insulating body 3. Recesses in the housing element 2 receive the locking elements 4 along the circumference of the housing element 2. The locking elements 4 are formed as detent hooks and are provided for a push-pull locking mechanism. The spring element 6 for shield connection, also received by the housing element 2, can be seen. The spring element 6 is located in a substantially congruent recess 7, wherein a portion of the recess 7 receives a circumferential ring 8 of the spring element 6. The wings 9 of the spring element 6 reside between the locking elements 4 in pocket-like portions of the recess 7. Furthermore, it can be seen that the locking elements 4 and the wings 9 of the spring element 6 alternate circumferentially on the housing element 2. Likewise, it can be seen that the wings 9 arranged on the ring 8 of the spring element 6 are oriented opposite to the plug-in direction R.sub.S. In order to separate the locking elements 4 from the spring element 6, webs, which result from the recesses of the locking elements 4 and the recess 7 for the spring element 6, can be seen on the housing element 2 in the illustrated embodiment of the round plug connector 1.
[0041] FIG. 2 shows a spring element 6 according to the invention, whereby the structure of the spring element 6 can be clearly seen. The spring element 6, which is produced by a stamping process, for example, initially has a ring 8 which has a gap. This gap results from the production process and the following deforming process, for example a rolling process or a roll bending process. The wings 9 provided for contacting the mating plug connector 5 are connected in an integrally bonded manner to the ring 8. For this purpose, the wings 9 are usually integrally molded on during the stamping process, or left on the ring 8. During a deforming process, the wings 9 are given their outwardly directed, concave shape. In principle, the wings 9 can be joined to the ring 8 by integral bonding processes, for example by soldering processes or welding processes. The wings 9 remain substantially outside an imaginary cylinder of which the diameter assumes the inner diameter d.sub.I of the ring. The wings 9 have one end each, wherein in a preferred embodiment the ends remain inside an imaginary hollow cylinder, the base of which can be represented substantially by the outer diameter d.sub.A and the inner diameter d.sub.I of the ring 8.
[0042] FIG. 3 and FIG. 4 show a fundamentally comparable construction of a plug connection, comprising a plug connector 1 and a mating plug connector 5. However, the embodiments of the spring elements 6 differ. In FIG. 3, the spring element 6 is shown with a wing 9, which extends from the ring 8 to the housing element 2′. The end of the wing 9, which is arranged opposite to the plug-in direction R.sub.S, comes into contact with the housing element 2 at least to some extent. In FIG. 4, a shorter wing 9′ is shown compared to the wing 9. This wing 9′ does not contact the housing element 2. The spring element 6 contacts the housing element 2 only through the ring 8. Despite the shortened design, the wing 9′ is held in a secure position on the housing element 2 by the ring 8 and can provide a similarly secure shield connection. The concave shape of the differing wings 9 and 9′ of the spring elements 6 is particularly clear in both figures. Similarly, FIGS. 3 and 4 illustrate why the concave wings 9 and 9′ simplify the plugging process between the round plug connector 1 and the mating plug connector 5. The latching hook 10 in the mating plug connector 5 is slid over the wings 9 and 9′ by the concave embodiment of the spring elements 6. Both during the plugging process and during the release process of the plug connection, the spring elements 6 do not inhibit the processes or inhibit them at least only to a reduced extent.
[0043] FIGS. 5 to 8 illustrate an alternative embodiment of the round plug connector 1, initially showing a substantially identical structure of the round plug connector 1. However, the alternative embodiment of the spring element 6′ also necessitates a change in the housing element 2. Since the spring element 6′ has a ring 8′, which is reminiscent of a retaining ring in terms of shape and orientation, it makes sense to provide the recess 7 with a further recess 7′. For this purpose, it is convenient to form the recess 7′ as a groove substantially congruent to the ring 8′. To ensure that the wings 9 continue to run substantially axially, they must be deformed on the ring 8′. A sag bending process is suitable for this purpose. In order for the wings 9 to continue to be substantially axially oriented on the housing element 2 of the round plug connector 1, the wings 9 must be integrally molded on the ring 8′ with at least one angle of greater than or equal to 45°. Particularly preferably, an angle of greater than or equal to 60°, in particular an angle of substantially 90°, is selected. The ring 8′ engaging in the recess 7′, which is preferably embodied as a groove, secures the spring element 6′ in the axial direction in a particularly advantageous manner.
[0044] Even though various aspects or features of the invention are shown in each case in combination in the figures, it is apparent to a person skilled in the art - unless otherwise indicated - that the combinations shown and discussed are not the only possible ones. In particular, corresponding units or feature complexes from different exemplary embodiments may be interchanged with each other.
[0045] The articles “a” and “an” as used in this application should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
