  • the elastic component is formed as a leg with a circumferential ridge, wherein the leg serves to rest the electronics unit and wherein the web is used as Dichlor. It has proved to be a disadvantage that the web does not ensure reliable sealing of the housing formed in the receptacle when an approximately radial force with respect to its surface is applied to the lid.
  • the US 2004/201512 A1 discloses an electronic key with a housing and a housing cover, between the housing and the lid, a sealing element is provided, which is annular and ensures no secure seal against radial displacement of the lid.
  • the invention provides that on the recording, a sealing element is arranged inextricably surrounding the contact elements, and the lid rests with its underside on the sealing element, whereby a reliably sealed receptacle is formed, which is limited by the lid and the housing substantially.
  • the sealing element has a first and a second sealing region, wherein the sealing element is formed with a groove open on one side to the lid, which separates the first and the second sealing region from each other.
  • the first and the second sealing region are integrally connected and centreinhetlich each other and form the sealing element, which is preferably molded onto the first collar member.

During the fastening of the cover to the housing, among other things deform the locking means of the lid and snap into the counter-latching means, creating an exact fit of the lid on the housing. Since the locking means of the lid have a corresponding low strength, there is no risk that during assembly, for example, it comes to a breaking out of the locking means.

To open the lid, the mechanical key is removed from its compartment and guided with its tip into said opening. Here is the tip of the mechanical key between the rear edge region of the lid and the housing.
  • the opening for releasing the lid for receiving through the wall is closed. This prevents that the object is guided too far into the housing, whereby, for example, the interior, in particular the sealing element, could be damaged.
  • the underside of the lid has at least one retaining element extending in the direction of the receptacle, which contacts the energy store in the closed state of the lid, whereby the energy store is held reliably in its position within the receptacle.
