Embodiment Construction

[0024] 1A to 1D show a conventional installation method of battery terminals. FIG. 1A shows that the conductive terminal 52 is insulated from the metal container wall 56 by a layer 54 of non-conductive bonding material. Layer 54 is bonded with ceramic fusion, glass fusion or epoxy. Due to such a construction, there is no permanent compressive force between the non-conductive material and the terminal, and earth leakage protection relies on the adhesive properties of the material. In addition, the insertion process of non-conductive materials is very expensive. It is also difficult to apply a non-conductive material uniformly around the terminal without creating air bubbles that impair adhesion and hermetic seals.

[0025] Another conventional technique, shown in FIG. 1B , is to apply a rubber O-ring 63 at the junction of the conductive terminal 62 and the metal container wall 68 . When lock nut 64 is installed on terminal 62, a compressive force is generated which acts on i...

Abstract

A terminal assembly for sealing and electrically isolating a conducting terminal from a container of an electrolytic device uses a lock nut and a single-piece deformable gasket. When the lock nut is threaded down the terminal, an inwardly tapered sleeve of the lock nut cooperates with an outwardly tapered zone of the gasket to force the gasket to surround the opening of the container and to seal the terminal before compression is applied. Reliable sealing and electrical insulation are provided because predetermined axial and radial compression forces are generated on the opening of the container. A robust sealed terminal is provided while over compression of the single-piece gasket is prevented.

Description

technical field [0001] The present invention relates to electrically conductive terminals secured to vessels of an electrolysis device, in particular battery terminal seals. Background technique [0002] It is well known that in the art of manufacturing electrochemical cells a key issue is the construction and protection of the hermetic seal between the conductive terminals and the container cover. A related problem is the electrical insulation of the opposite polarity terminals in order to prevent short circuits which would prevent the proper functioning of the electrolysis process within the cell. Where the container has a metal support surface, at least one polarity terminal must be hermetically sealed and electrically insulated from the container, the container itself serving as the second polarity terminal. [0003] US Patent No. 5,663,015 to Hooke et al. and assigned to "Hawker Energy Products, Inc." discloses a method of making a battery terminal seal. A molded plas...
