Abstract

A connecting apparatus detachably connects two assemblies. The connecting apparatus includes a fastener module securable to a first of the assemblies and including a negative-pressure element, and an attachment component of a second of the assemblies. The negative-pressure element is connectable in an attachment direction to the attachment component for connecting the assemblies with one another, wherein, in a connected position, the negative-pressure element interacts with the attachment component such that, in the event of a load acting in between the fastener module and the attachment component opposite to the attachment direction, the negative-pressure element and the attachment component are held against one another by a negative pressure acting between the negative-pressure element and the attachment component. The fastener module includes an adjustment element which is adjustable relative to the negative-pressure element and which is movable relative to the negative-pressure element.

First claim

The invention claimed is:

1. An assembly group, comprising:
an electronic device, and
a connecting apparatus for detachably connecting the electronic device to a further assembly, wherein the connecting apparatus comprises a fastener module having a negative-pressure element connectable in an attachment direction to an attachment component for connecting the electronic device to the further assembly, wherein the negative-pressure element, in a connected position, interacts with the attachment component such that, in the event of a load acting in between the fastener module and the attachment component opposite to the attachment direction, the negative-pressure element and the attachment component are held against one another by a negative pressure acting between the negative-pressure element and the attachment component,
wherein the fastener module comprises a first magnet element for magnetically assisting the connection of the electronic device to the further assembly,
wherein the negative-pressure element is formed by a cup element, said cup element comprising a body and a flexible edge portion radially protruding from and circumferentially extending about the body, said flexible edge portion being configured to be elastically deformed for causing said negative pressure,
wherein the connecting apparatus further comprises an attachment assembly, the attachment assembly being securable to the attachment component and comprising an attachment part, the fastener module being configured to be operatively connected to the attachment part, said fastener module comprising a first positive-locking portion and the attachment part comprising a second positive-locking portion, and;
wherein the first positive-locking portion and the second positive-locking portion are configured, during attachment of the fastener module and the attachment part to one another, to engage with one another in order to counteract a transverse movement between the fastener module and the attachment component.

2. The assembly group as claimed in claim 1 , wherein the first magnet element is arranged on the negative-pressure element.

3. The assembly group as claimed in claim 1 , further comprising a second magnet element, which is securable to the attachment component, for magnetic interaction with the first magnet element of the fastener module.

4. The assembly group as claimed in claim 1 , wherein the fastener module comprises at least one electrical contact element for electrical contacting, in the connected position, with at least one counterpart contact element associated with the attachment component.
