  • the upper part 103 has a power connection, not shown in detail in the figures. This is in the intended use in electrical connection with a power source, such as the public power grid. All electrical consumers provided by the device 101 are coupled in the intended use case to the device-internal mains connection housed by the upper part 103, as are the electrical consumers accommodated by the lower part 102, for example a pump arranged in the vacuum chamber.
  • a spring contact strip 105 arranged on the upper part 103 as well as a contact point strip 107 cooperating therewith and arranged on the lower part 102 are provided in the exemplary embodiment shown.
  • the spring contacts 104 of the spring contact strip 105 are electrically contacted at the respectively associated contact points 106 of the contact point strip 107, so that a current flow can take place from the mains connection of the upper part 103 to the electrical consumers of the lower part 102.
  • the lower part 102 has a base member 108 which projects beyond the upper edge 103 of the lower part 102 facing the upper part 103 in the height direction 112.
  • This base element 108 has an upper side 109 facing the upper part 103.
  • This upper side 109 of the base element 108 provides the contact points 106 of the contact point strip 107.
  • a recess in the form of a recess 110 is provided on the upper part 103, which provides a volume space 111.
  • This volume space 111 is accessible through an opening 115 in the base plate 114 of the upper part 103.
  • the spring contacts 104 of the spring contact strip 105 are arranged.
  • the base element 108 engages in the recess 110, so that it comes to forming an electrical contact between the spring contacts 104 and the contact points 106.
  • the moment of contacting the spring contacts 104 in accordance with the arrows 121 spring-loaded return, whereby a secure contact of the spring contacts 104 is secured to the associated contact points 106.
  • FIGS. 4 and 5 let each in a schematic representation of the formation of base member 108 and recess 110 in detail closer.
  • the recess 110 serves the base element 108 at the moment of merging, that is, during assembly of the upper part and lower part as a guide.
  • the base 108 emerges for the purpose of contacting the contact points 106 provided by the base element 108 with the spring contacts 104 in the volume space 111 provided by the recess 110.
  • the lateral boundary wall of the recess 111 serves as a guide surface for the base element 108.
  • the provided by the recess 110 volume space 111 exceeds the spring contacts 104 in height direction 122 of the spring contacts 104. This ensures that it comes to contacting the spring contacts 104 with the associated pads 106 only when the base member 108 into the recess 110 already immersed and applied to the serving as a guide surface side wall of the recess 110. On unwanted tilting is prevented.
  • a torsion protection is given, because the base element 108 and the associated recess 110 are formed in cross-section deviating from the circular shape, as in particular the FIGS. 6 and 7 reveal. This ensures at the moment of immersion of the base member 108 in the recess 110, the upper part 103 and lower part 102 can not be rotated relative to each other.
  • FIGS. 6 and 7 can be seen further, with respect to the spring strip 105 a total of four spring contacts 104 and with respect to the contact point strip 107 also four contact points 106 are provided. For screwing the spring contact strip 105 with the upper part or for screwing the contact point strip 107 with the lower part 102 corresponding holes 119 are provided.
  • the inventive design of recess 110 on the one hand and base member 108 on the other hand serves to protect the spring contacts 104 protectively and provide a guide to the simplified orderly arrangement of the upper part 103 on the lower part 102.
