t. Can be attached to the housing in which the previously inserted Has found the use of insulating material. As a result of its permanent attachment to the housing, subsequent relocation is possible of the intermediate body on the housing impossible. Once there is the plug-in device part set up for a specific purpose within the group, this intended purpose remains obtain. In this way, there is a high level of security in the event of a renewal the plug-in device part by replacing the insulating material insert given. The flat shape of the intermediate body has the advantage that the intermediate body is lightly made of plate material can be produced by punching. Even if the intermediate body is out Sheet metal is made in order to obtain a particularly high strength, so it can be by using a ring shape or Arrange the ring part shape in such a way that the required minimum insulation and insulation paths are observed. A Another advantage of the invention is that the flat intermediate body is supported directly on the housing. More between Housing and intermediate body lying spacers, which occupy the line connection space located on the insulating material insert would not exist. As a result of the flat shape of the intermediate body, the intermediate body is permanently attached on the housing in the vicinity of the plane going transversely to the main axis of the plug-in device part, in which the attachment of the Insulating material insert takes place on the intermediate body.
