Abstract

Add-on housing for a plug-in connection, which add-on housing has a housing side with at least one first fastening form and a plug-in side with at least one holding form, wherein a flange is arranged between the housing side and the plug-in side, which flange is provided for attaching the add-on housing to an appliance housing, wherein the plug-in side has at least two holding forms, at least one first holding form and at least one second holding form.

Claims

1. An add-on housing (1) for an electrical plug-in connection, comprising: a housing side (2) with a first fastening form (3) and a plug-in side (5) with at least two holding forms (6, 6), including a first holding form (6) and a second holding form (6), for reversible fastening of a plug-in connector, wherein a flange (4) is arranged between the housing side (2) and the plug-in side (5), the flange being provided for attaching the add-on housing (1) to an appliance housing, and wherein the add-on housing (1) has a through-hole (7) along a longitudinal axis of the add-on housing (1), the through-hole (7) being designed to receive an insulating body with contact elements located therein, wherein the flange (4) is configured for attachment to an outside of the appliance housing and the first fastening form (3) is configured to securing the add-on housing (1) inside the appliance housing, wherein the first holding form (6) is a circumferential bead adapted to receive a snap closure of a snap-in connector, wherein the second holding form (6) is a circumferential groove adapted to receive a latching closure (13) of a push-pull connector, and wherein the circumferential bead is arranged between the flange (4) and the circumferential groove.

2. The add-on housing (1) as claimed in claim 1, wherein the through-hole (7) has a further form which is configured to receive a latching element that differs from the snap closure and the latching closure.

3. A plug-in connector system comprising the add-on housing (1) in accordance with claim 1 and a set of corresponding electrical plug-in connectors, wherein the set of corresponding electrical plug-in connectors includes the snap-in connector (10) with the snap closure (12) and the push-pull connector (10) with the latching closure (13), and wherein the add-on housing (1) is adapted to alternatively receive the snap-in connector (10) or the push-pull connector (10).

4. The plug-in connector system as claimed in claim 3, 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 snap closure (12) and the latching closure (13).

5. The add-on housing (1) as claimed in claim 1, wherein the circumferential bead and the circumferential groove are separated from one another by a cylindrical portion on the plug-in side whereby the snap closure of the snap-in connector is prevented from incorrectly becoming connected to the circumferential groove.

6. The add-on housing (1) as claimed in claim 1, further comprising a circumferential depression arranged between the circumferential bead and the flange (4).

7. The add-on housing (1) as claimed in claim 1, wherein the add-on housing (1) is configured for being mounted to the appliance housing from the plug-in side.

8. An assembly, comprising: the add-on housing (1) as claimed in claim 1; and the appliance housing, wherein the flange (4) is attached to an outside of the appliance housing and the first fastening form (3) secures the add-on housing (1) inside the appliance housing.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) An exemplary embodiment of the invention is illustrated in the drawings and will be explained in greater detail below.

(2) FIG. 1 shows a perspective representation of an add-on housing.

(3) FIG. 2 shows a representation of the add-on housing in longitudinal section.

(4) FIG. 3 shows a detail of an add-on housing with the snap-collar connector plugged in.

(5) FIG. 4 shows a detail of an add-on housing with the push-pull connector plugged in.

DETAILED DESCRIPTION

(6) 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.

(7) 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.

(8) 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.

(9) 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.

(10) 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.

(11) 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.

(12) 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 artunless otherwise specifiedthat 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.
