Protective direct current voltage and current high-precision collector

Abstract

The application discloses a kind of protective direct-current voltage current high-precision collector, it is related to current voltage measuring instrument technical field.The collector shell and the collector main body being arranged in the collector shell inside are included in the top of the collector main body is provided with the cover No.1, the bottom of the collector main body is provided with the cover No.2 and the cover No.3 on the side of cover No.2, the side of cover No.2 is provided with the fence, and the cover No.3 is movably connected to the side of cover No.2 by the fence.Compared with the existing collector on the market, the measurement interface, function keys and display screen on the collector main body are protected by unfolding the protection assembly, effectively avoiding the corrosion of the collector main body by water stains, dust or other pollutants, resulting in corrosion, inoperability and poor measurement accuracy of the measurement interface, the collector main body is protected by the cover No.1, cover No.2 and cover No.3, effectively avoiding the situation that the collector main body is bumped, and it is more resistant to drop and impact.
