ABSTRACT:
A coaxial terminal construction for a sealed pressurized battery. The battery includes a sealed vessel containing a series of battery cells and positive and negative poles are connected to the cells. A pre-assembled terminal unit extends through an annular mounting flange that is secured within an opening in the vessel wall and the pre-assembled unit includes an inner electode, an outer electrode, which is disposed concentrically outward of the inner electrode and insulated therefrom, and an annular mounting member which is located concentrically outward of the outer electrode and insulated therefrom. All three concentric members have external threads of the same pitch. The terminal unit is installed by threading the mounting member in the mounting flange of the vessel and simultaneously threading the outer electrode with a nut connected to one of the poles and threading the inner electrode with a second nut connected to the other of the poles. The mounting member can be crimped inwardly to provide a seal between the three concentric members.
