Abstract
A reverse protector comprises a transformer, a diode, a bridge rectifier and an outer case. 220V alternating current is transformed to 14.5V by the transformer and then is converted to direct current by rectification of the bridge rectifier to be transmitted to a charging cable, so that a storage battery is charged. At the moment, if a positive pole and a negative pole of the 12V storage battery are connected reversely, a rectification circuit cannot form a return circuit by the aid of a reverse blocking function of the diode, and electric energy cannot be transmitted, so that the function of failing in charging during reverse connection of the positive pole and the negative pole of the storage battery is achieved. The reverse protector has the advantage that the defect of fire disasters caused by reverse connection of the positive pole and the negative pole of the storage battery can be overcome.
Description
Technical field
The utility model relates to a kind of external electric energy replenishment system of storage battery, is a kind of reverse protection device concretely.
Background technology
Storage battery generally adopts external charger to be used as the overwhelming majority that accounted for of electric energy supplement after using a period of time; This mechanism simple structure; Easy to maintenance; But there is obvious weak point: because behind the power connection, just through lead output, the positive and negative terminal of storage battery connects the hidden danger that instead will cause causing fire to the electric energy of charger.
Summary of the invention
The purpose of the utility model is to provide a kind of reverse protection device, makes guaranteeing on the simply constructed basis of former charger, also has to prevent that the accumulator positive negative terminal from connecing the anti-fire that causes.
The utility model is realized with following technical scheme: this a kind of reverse protection device is made up of transformer, diode, bridge heap rectifier, outer container.It is characterized in that: the input that transformer, diode, bridge heap rectifier, bridge heap rectifier are housed in the inside of outer container is connected with transformer, and the negative pole of bridge heap rectifier output end is connected with the negative electrode of diode, and the anode of diode is drawn a charging negative line.At first the 220V alternating current is transported to charging wire after converting direct current to behind the bridge heap rectifier rectification after the transformer transformation becomes 14.5V, and storage battery has been accomplished charging requirement; At this moment, if the both positive and negative polarity of 12V storage battery connects instead, because of the reverse function of ending of diode, rectification circuit can not form the loop, and electric energy can't be carried, and has realized that accumulator anode and cathode connects instead not charge function.
The beneficial effect of the utility model is: the utility model can solve the drawback that the accumulator anode and cathode reversal connection causes fire.
