Abstract
A charger output protector is composed of a transformer, a diode, a bridge rectifier, a 12V relay and an outer box. 220 V alternating current is transformed to be 14.5V through the transformer, converted into direct current through the bridge rectifier and transmitted to the D1 end of the 12V relay. Due to the fact that the 12V relay does not pick up, electricity energy at the D1 end cannot be output outwards through the C1 end. When a storage battery is connected with the protector, electricity energy of the storage battery reaches a coil of the 12V relay through a diode 1, the relay is conducted to pick up, and charging requirements are finished. At this time, if the anode and the cathode of the 12V storage battery are reversely connected, the relay cannot form a loop due to a reverse stopping function of the diode 1, the 12V relay cannot work, electricity energy cannot be transmitted, and a function of non-charging when the storage battery is not connected or when the anode and the cathode of storage battery are reversely connected.
Description
Technical field
The utility model relates to a kind of external electric energy replenishment system of storage battery, is a kind of charger output 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 have obvious weak point: because behind the power connection, direct current is just exported; If positive and negative terminal connects together causing the charger heavy-current discharge, cause causing the hidden danger of fire.
Summary of the invention
The purpose of the utility model is to provide a kind of charger output protection device, makes guaranteeing on the simply constructed basis of former charger also have the fire that prevents that the charger electric leakage from causing, can be used as the charger output protection device of the external electric energy supplement of storage battery.
The utility model is realized with following technical scheme: this charger output protection device is made up of transformer, diode, the rectification of bridge heap, 12V relay, outer container.It is characterized in that: transformer, diode, the rectification of bridge heap, 12V relay are housed in the inside of outer container, and the input of bridge heap rectification is connected with transformer, and the positive pole of output is connected with the D1 end of 12V relay; The negative pole of output is connected with the E1 end of 12V relay, and simultaneously, the E1 of 12V relay end is drawn a charging negative line; The anode of diode is connected with the F1 end of 12V relay; The negative electrode of diode is connected with the C1 end of 12V relay, and simultaneously, the C1 end is drawn a charging electrode line.At first the 220V alternating current is transported to the D1 end of 12V relay after converting direct current to after the bridge heap rectification rectification after the transformer transformation becomes 14.5V, and because of the 12V relay does not have adhesive, the electric energy fails of D1 end is crossed the outwards output of C1 end; After storage battery connected upward, the electric energy of storage battery was through the coil of diode 1 arrival 12V relay, and charging requirement has been accomplished in relay conducting adhesive; 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 1, relay can not form the loop, and the 12V relay is not worked, and electric energy can't be carried, and has realized that nothing connects storage battery or 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 charger short circuit causes fire, has the function that solves charger short circuit electric leakage simultaneously, thereby improves the useful life of charger.
