Abstract

An electrode, particularly a miniature electrode, having structural integrity and reliable electrical operation results. A thin fluoroplastic liner, preferably, a TFE fluorocarbon liner, seals an electrode disc core to a PCTFE fluoroplastic shroud. By properly machining and assembling the electrode disc core, TFE fluorocarbon liner and PCTFE fluoroplastic shroud, a fluid tight interference seal is obtained to avoid the electrolytic fluid leaking into the electrode to corrode the conductive electrical path. A stainless steel spring extends between the electrode disc core and an electrode contact in the PCTFE fluoroplastic shroud to complete the conductive path through the electrode. The spring has two flat ends which are held in reliable surface contact with the disc core and the electrode contact by the bias of the spring itself. The spring thus provides a reliable electric connection with good conductivity.
