Abstract
A structure of an electrode unit for applying electricity to a conductible substance (4) installed in a metallic housing (2) has a metallic electrode (6) connected to a portion of the conductible substance (4), an insulating member (8, 8') positioned between the electrode (6) and the metallic housing (2), and a metallic sealing material (10,10') to be transformed by fastening a nut so as to secure sealability between the electrode (6) and the insulating member (8) and between the metallic housing (2) and the insulating member (8). The structure of an electrode unit is excellent in an insulating property and a gas sealability between the metallic housing (2) and electrode (6) and therefore has high reliability.

An electrode unit structure for applying electricity to a conductive substance provided in a metallic housing, comprising:
- a metallic housing;
- a metallic electrode for connection to a portion of a conductive substance provided in the metallic housing;
- an insulating member provided between the electrode and the metallic housing;
- metallic seals respectively provided between the electrode and the insulating member and between the metallic housing and the insulating member;
- clamping means for providing a clamping force to secure the electrode to the metallic housing, said clamping means comprising a metallic member engaging the metallic electrode;
- and
- a spring member provided between the metallic member and the insulating member to absorb a difference in thermal expansion between the metallic member and the insulating member.
