Problems solved by technology

When the light is dark, or the positive and negative marks on the charger are blurred, it is easy to reverse the positive and negative poles. When the two poles are reversed, the output current is extremely large, resulting in a short circuit, which will cause the power supply and related equipment is compromised

Abstract

The invention discloses an auto-pole, which consists of mechanic propulsive device and circuit board device through circuit connection, wherein the mechanic propulsive device contains magnetic inductance device, contact piece device and case; the circuit board device concludes control circuit and inner battery; the control circuit contains first and second photoelectric couplers through circuit connection and first and second transistors of first and second photoelectric couplers through base connection separately. The invention can correct positive and negative pole of connecting end automately, which avoids short circuit and relative danger.

Description

Technical field [0001] The invention relates to an automatic pole, which can be used for automobile emergency power supplies, and belongs to the technical field of automobile emergency power supplies. Background technique [0002] Generally, when using a car’s emergency power supply for charging, it is necessary to manually distinguish the positive and negative connections. Red means that the positive electrode should be connected, and black means that the negative electrode should be connected. When the light is dark, or the positive and negative marks on the charger are blurred, the positive and negative poles are likely to be reversed. When the two poles are reversed, the output current is extremely large, resulting in a short circuit, which will cause the power supply and related The equipment is damaged. Summary of the invention [0003] The automatic pole provided by the present invention uses simple circuit elements to automatically correct the positive and negative poles...
