## 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

### Claim 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.

### Claim 2 (depends on 1)

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.

### Claim 3 (depends on 1)

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′).

### Claim 4 (depends on 3)

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).

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

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

### Claim 7 (depends on 1)

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.

### Claim 8 (depends on 1)

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.
