Abstract

The utility model relates to a battery adapter for converting small-size batteries into large-size batteries to be used conveniently and capable of preventing parallel connection short circuit of batteries, which comprises a body. A plurality of slots for the small-size batteries to be arranged in are arranged in the body. A positive pole sheet and a negative pole sheet contacting two poles of each small-size battery are arranged at two ends of the body, a positive pole protrusion of a large-size battery is arranged on the front side of the positive pole sheet, and a plurality of positive connecting protrusions contacting the positive poles of the small-size batteries are arranged on the back of the positive pole sheet. An insulation pad is arranged between the positive pole sheet and the small-size batteries, and a plurality of through holes corresponding to the plurality of small-size batteries are arranged on the insulation pad. The diameter of the through holes is larger than that of the positive pole connecting protrusion and positive pole protrusions of the small-size batteries. The diameter of the through holes is smaller than that of a metal end face of negative poles of the small-size batteries, and the thickness of the through holes of the insulation pad is smaller than a sum of the thickness of the positive pole protrusions and the thickness of the positive connecting protrusion. When users place the positive poles and negative poles of the small-sized batteries wrongly, phenomena of batteries of heating, fluid flowing and even burning are effectively avoided. Furthermore, use is convenient, and the structure is simple.
