Abstract (en)
[origin: EP0734040A1] The connection appts. connects a suction joint (1) of a vacuum pumping installation to the neck (10) of the tube in a jig with lateral guidance rollers (4) running on rails (6) whose profile causes levers (5) to be pivoted slightly outwards against compression springs (9). This movement varies the spacing between centring rollers (8) which guide the evacuation stem (11) of the tube safely into the sealing ring (13) of the suction joint. At the same time spring contacts (15) in a holder (16) are brought up to connections (12) with the tube cathode until contact is made with the roller (18) of a release unit (17).
