Abstract
The utility model relates to a charging protector with inverse connection of a positive electrode and a negative electrode. The mechanical components of the charging protector comprise a relay and a diode. The charging protector is characterized in that the anode of the diode is connected with the end C1 of the relay, the cathode of the diode is connected with the end A1 of the relay, a positive electrode power supply outlet lead is led out from the end A1, a negative electrode power supply inlet lead and a negative electrode power supply outlet lead are connected with the end C of the relay, and a positive electrode power supply inlet lead is led out from the end D of the relay. The charging protector has the beneficial effects that a storage battery can not be charged due to the inverse connection of the electrodes of the storage battery.
Description
Technical field
The external electric energy that the utility model relates to a kind of storage battery replenishes protective device, is concretely a kind ofly to have both positive and negative polarity and connect anti-charging protector.
Background technology
Storage battery is during with external charger electric energy supplement, and is anti-if both positive and negative polarity output connects, and will cause the charger heavy-current discharge, and the hidden danger that causes fire is arranged.
Summary of the invention
The purpose of this utility model is to provide a kind of to be had both positive and negative polarity and connects anti-charging protector, has to prevent that accumulator anode and cathode from connecing the function of the anti-fire that causes.
The utility model is realized with following technical scheme: this is a kind of to have both positive and negative polarity and connects anti-charging protector and be made up of relay, diode.It is characterized in that: the anode of diode is connected with the C1 of relay end, and the negative electrode of diode is connected with the A1 of relay end, and the A1 end is drawn the cathode power supply outlet, and the negative pole inlet wire is connected with the C end of relay with outlet, and the D end of relay draws an anodal inlet wire.After storage battery connect to be gone up, the electric energy of storage battery arrived the coil of relay through diode cathode, the relay adhesive, and electric energy is carried and is finished effect to the storage battery electric energy supplement by anodal output line to the A1 end from the D end of relay; When the both positive and negative polarity of storage battery connects instead, diode reverse is ended, and electric current can not form the loop, and the D end of relay can not be connected with the A1 end, and electric energy can't be carried, and has realized not connecing storage battery or accumulator anode and cathode connects instead not charge function.
The beneficial effects of the utility model are: have and realize that battery terminal connects the function of instead not charging.
Description of drawings
To be that the utility model is a kind of have a structural map that both positive and negative polarity connects anti-charging protector to Fig. 1.
1. relays, 2. diode among the figure.
Embodiment
To be that the utility model is a kind of have a structural map that both positive and negative polarity connects anti-charging protector to Fig. 1; its structure is made up of relay 1, diode 2; in Fig. 1: the anode of diode 2 is connected with the C1 end of relay 1; the negative electrode of diode 2 is connected with the A1 end of relay 1; the A1 end is drawn the cathode power supply outlet; the negative pole inlet wire is connected with the C end of relay 1 with outlet, and the D end of relay 1 draws an anodal inlet wire.
