Abstract
The utility model discloses a kind of battery-driven car charge port possessing unidirectional charging, this battery-driven car charge port, comprise plug, positive pole cable is connected with between described plug and the positive pole of battery, negative pole cable is connected with between described plug and the negative pole of battery, described positive pole cable is in series with a zener diode, and the closure of described zener diode is consistent with charging current direction.Described charging current direction be on positive pole cable from plug one end to the positive pole of battery.Battery-driven car charge port of the present utility model adopts the unilateral conductivity of zener diode, electric current flows through with a direction from zener diode only, can prevent the plug place short circuit flowing to external charge mouth outside electric current from causing burning out of related device by actv., or even cause the situation of car load spontaneous combustion, the vehicle security energy of battery-driven car can be effectively raised.
Description
Technical field
The utility model relates to a kind of battery-driven car charge port parts, especially relates to a kind of battery-driven car charge port possessing unidirectional charging.
Background technology
Current battery-driven car external charge mouth on the market all adopts cable to make direct conducting between battery and charge port, this just brings a problem: external charge mouth is not when charging the battery, the plug of external charge mouth also there is voltage, as in careless or careless situation, metal object is to the both positive and negative polarity short circuit of charge port, will cause on fire, thus damage other related devices, the battery-driven car that also can cause that situation is serious burns, a lot of battery-driven car fire accident is all caused by above reason on the market at present, solve this safety issue, battery-driven car is played a very important role.
Utility model content
For the deficiency of above-mentioned technical matters, the utility model provides a kind of battery-driven car charge port possessing unidirectional charging, can meet when not charging the battery, and the plug place Non voltage output of external charge mouth, would not produce short circuit phenomenon.
In order to solve the problems of the technologies described above, a kind of battery-driven car charge port possessing unidirectional charging that the utility model proposes, this battery-driven car charge port, comprise plug, positive pole cable is connected with between described plug and the positive pole of battery, be connected with negative pole cable between described plug and the negative pole of battery, described positive pole cable is in series with a zener diode, the closure of described zener diode is consistent with charging current direction.
Charging current direction described in the utility model be on positive pole cable from plug one end to the positive pole of battery.
Compared with prior art, the beneficial effects of the utility model are:
The utility model external charge mouth utilizes the unilateral conductivity of zener diode, electric current can only flow through from one end of zener diode, external charge mouth with car load connection after plug place Non voltage output, actv. prevents plug place outlet short circuit phenomenon, zener diode also has pressure stabilization function, when zener diode is oppositely connected, when diode is breakdown, its electric current will increase instantaneously, when external voltage increases, the electric current of the breakdown rear increase of diode can by diode without with in the load of diodes in parallel, thus components and parts in parallel with it can be protected.On the positive pole cable of external charge mouth except series winding zener diode, can also to contact and zener diode principle or other electronic devices and components intimate also can reach this effect.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation possessing the battery-driven car charge port of unidirectional charging of the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are described in further detail.
As shown in Figure 1, a kind of battery-driven car charge port possessing unidirectional charging of the utility model, comprise plug 1, positive pole cable 21 is connected with between described plug 1 and the positive pole of battery 3, negative pole cable 22 is connected with between described plug 1 and the negative pole of battery 3, described positive pole cable 21 is in series with a zener diode D, the closure of described zener diode D is consistent with charging current direction, described charging current direction be on positive pole cable 21 from plug one end to the positive pole of battery 3, the direction of arrow as shown in the I in Fig. 1.
Use the utility model external charge mouth when charging the battery; utilize the unilateral conductivity of zener diode; electric current can only flow through from zener diode one end; when not using external charge mouth to charge the battery; the plug place Non voltage output of external charge mouth, now protects the short circuit problem with external charge mouth effectively.External charge mouth of the present utility model with car load connection after plug go out Non voltage output, actv. prevents the outlet short circuit of plug place and causes the phenomenons such as on fire, burning.
Although be described the utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of it is restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; when not departing from the utility model aim, can also make a lot of distortion, these all belong within protection of the present utility model.
