Abstract
The invention discloses an automatic positive-finding probe assembly. The assembly comprises a current probe, a voltage probe which is inserted into a lower end of the current probe and can move up and down relatively, a probe sleeve and a positive-finding sleeve. The current probe comprises a lower connection portion and an upper extension portion. A diameter of the upper extension portion is less than that of the lower connection portion. The probe sleeve is recessed downwardly from an upper end surface so as to form a truncated cone-shaped groove which is wide at the top and narrow at the bottom. The positive-finding sleeve is arranged to be in a corresponding truncated cone shape which is wide at the top and narrow at the bottom. The upper extension portion of the current probe passes through the probe sleeve from bottom to top. The positive-finding sleeve is fixed to the upper extension portion of the current probe and is arranged in the truncated cone-shaped groove of the probe sleeve. A first spring sleeves the upper extension portion of the current probe. An upper end of the first spring abuts against the probe sleeve. The positive-finding sleeve moves upwardly and can incline towards any direction relative to the probe sleeve after being independent of cooperation of the truncated cone-shaped groove. And then the voltage probe and the current probe incline till that a contact surface is parallel to a contact surface of a cell to be measured. The assembly of the invention can be suitable for tests of most of cells.
