Connector device, particularly for fastening current conductors to carbon electrodes

Claim 1

AN ELECTRODE COMPRISING A CARBON ELELCTRODE HAVING A SOCKET CAVITY, A CONNECTOR DEVICE FOR JOINING A CURRENT CONDUCTOR WITH SAID ELECTRODE, SAID CONNECTOR DEVICE INCLUDING A METAL NIPPLE MEMBER ENGAGING SAID CAVITY, SAID NIPPLE MEMBER AND SAID SOCKET CAVITY BOTH HAVING A CROSS SECTION CONSTITUTED BY THE AREA WITHIN A SEGMENT OF THE SAME ARCHIMEDEAN SPIRAL, EACH OF SAID SEGMENTAL AREAS BEING CIRCUMSCRIBED BY SUBSTANTIALLY ONE FULL SPIRAL TURN REMOTE FROM TEH INNERMOST TURN OF THE SPIRAL AND BY A LINE TRANSVERSE TO AND JOINING THE RESPECTIVE ENDS OF SAID ONE TURN, THE RESPECTIVE SPIRAL CONTACT SURFACES OF SAID MEMBER AND CAVITY BEING ENGAGEABLE WITH EACH OTHER OVER SUBSTANTIALLY THE ENTIRE PERMETRIC EXTENT OF SAID SURFACES BY ROTATION OF SAID MEMBER ABOUT ITS AXIS RELATIVE TO SAID ELECTRODE, SAID NIPPLE MEMBER AND SAID SOCKET CAVITY DEFINING TOGETHER AN INTERVENING SPACE ALONG SAID SPIRAL FOR PERMITTING RRELATIVE ROTATION OF SAID NIPPLE MEMBER WITHIN SAID CAVITY.
