22. The plug-in connector system as claimed in claim 21, wherein the add-on housing (1) is designed to receive a third plug-in connector with a third latching element, wherein the third latching element differs from the first latching element (11) and the second latching element (11′).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] An exemplary embodiment of the invention is illustrated in the drawings and will be explained in greater detail below.

[0020] FIG. 1 shows a perspective representation of an add-on housing.

[0021] FIG. 2 shows a representation of the add-on housing in longitudinal section.

[0022] FIG. 3 shows a detail of an add-on housing with the snap-collar connector plugged in.

[0023] FIG. 4 shows a detail of an add-on housing with the push-pull connector plugged in.

DETAILED DESCRIPTION

[0024] The figures contain partially simplified schematic representations. Identical reference signs are used for the same, but possibly not identical, elements. Different views of the same elements could be scaled differently.

[0025] Directional indications such as “left”, “right”, “up” and “down” are to be understood with reference to the respective figure and can vary in the individual representations with respect to the represented object.

[0026] FIG. 1 shows an add-on housing 1 according to the invention with a housing side 2 and a fastening form 3 located thereon. The fastening form 3 is designed as a thread. Other fastening forms, for example hooks, barbs or similar variants, are likewise conceivable and feasible. The housing side 2 is separated from the plug-in side 5 by a flange 4. The plug-in side 5 in this case has a first holding form 6 and a second holding form 6′. Moreover, a through-hole 7 can be seen. This through-hole 7 is designed to receive an insulating body (not shown) and contact elements (not shown) contained therein. The holding form 6 in this case is a circumferential elevation. To be more precise, the holding form 6 is a preformed bead. In order to reinforce the effect of the holding form 6, a depression may be provided between the holding form 6 and the flange 4. The holding form 6′ is a circumferential depression. This holding form 6′ may be configured as a recess, in particular as a groove. Finally, the through-opening 7 is also provided with a recess 8. This recess 8 is at least provided to prevent an accidental and/or false orientation of a plug-in connector 10 or 10′ on the add-on housing 1. A further recess, groove, opening can be skillfully inserted within and/or omitted from the recess 8, in order to allow a further latching element of a further plug-in connector to engage, in order to detachably connect said plug-in connector to the add-on housing 1.

[0027] FIG. 2 shows a cross section along the longitudinal axis of the add-on housing 1. It is clear from this that the holding forms 6 and 6′ adopt different positions along the longitudinal axis. In this way, latching elements configured in different ways can be received. Moreover, this spacing of the holding element 6 and of the holding element 6′, in particular, prevents a latching element provided for the holding element 6 from becoming permanently connected to the holding element 6′ in an incorrect manner. The design of push-pull connectors and snap-in connectors, which differs in principle, means that the arrangement makes absolute sense. Push-pull connectors usually require more space or more ways to allow a latching element 11′/13, which is used, to engage with a holding form 6′ than is required, for example, by a snap-in connector with a holding form 6 provided therefor.

[0028] To better illustrate this, FIG. 3 shows a detail of an add-on housing 1 according to the invention and a corresponding plug-in connector 10. The plug-in connector 10 is a so-called snap-in connector. A flexible plastic molding forms the latching element 11. In the case which is shown, the latching element 11 is configured a snap closure 12. This snap closure 12 can be pushed over the holding form 6 configured as a bead by a chamfer in the region of the plug-in opening. As soon as the holding form 6 of the snap closure 12 has been overcome, the snap closure 12 locks behind the holding form 6, so that the plug-in connector 10 engages with the add-on housing 1.

[0029] FIG. 4 shows a similar detail to that in FIG. 3, but rather than a plug-in connector 10 with a snap closure 11, a plug-in connector 10′ with a latching closure 13 is shown. This latching closure 13 is an exemplary depiction of a so-called push-pull connector. A latching element of the latching closure 13 engages with the holding form 6′ in this case. In this way, the plug-in connector 10′ locks with the add-on housing 1.

[0030] Even if different aspects or features of the invention are shown in combination in each case in the figures, it is clear to the person skilled in the art—unless otherwise specified—that the combinations which are shown and discussed are not the only ones that are possible. In particular, units or groups of features which correspond to one another can be exchanged for one another from different exemplary embodiments. In addition, the articles “a” and “an” as used in this application and the appended claims should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
