Patent ID: 7248469

Claim:
A plug-in electronic module for plugging into a holding structure having a coupling partner with an electrical contact, the electronic module comprising: a housing; an electronic component configured in said housing; at least one external electrical contact connected to said electronic component, said external contact being fixed relative to said housing, said external electrical contact configured for contacting the electrical contact on the coupling partner during a plug-in operation in which the electronic module is plugged into the holding structure; and a mechanical protective device for protecting said electrical contact from mechanical contact when the electronic module is not plugged into the holding structure, said protective device exposing said electrical contact when the electronic module is plugged into the holding structure such that said electrical contact comes into contact with the electrical contact on the coupling partner; said protective device including a moving protective element being displaceable relative to said housing and being configured for moving between a first position and a second position; said electrical contact being protected when said moving protective element is in said first position; said electrical contact being exposed when said moving protective element is in said second position; said moving protective element moving from said first position to said second position when the electronic module is plugged into the holding structure, wherein the moving protective element retracts to a position at least partially within the housing when moving from the first position to the second position.
