Abstract
A battery test contact clamp assembly is set forth. In one embodiment, upper and lower printed circuit boards are spaced apart on four corner located mounting rods of conductive metal. The four rods pass through one of the boards and are held to it by a set of detents and four hubs located at corners to thereby define a rectangular structure where the boards can move closer together or further apart. Frictional mounting hubs are used for the four rods. They are connected electrically in a circuit which involves contact assemblies on the two boards and they are aligned with battery terminals for contact to thereby define an electrical flow path with a test circuit. The contacts are aligned with the battery terminals. Alternative embodiments include two boards with multiple conducting rods there between and they are connected in several independent test modules. Another embodiment features two test contacts mounted on a common board for testing of batteries having two terminals at one end of the battery.
