Abstract
The utility model discloses a charge connecting wire for an electric vehicle battery jar, which comprises a charging interface, a first conducting wire and a second conducting wire, wherein, the charging interface is composed of a positive wiring terminal, a negative wiring terminal and an insulating shell outside the charging interface; one ends of the first and the second conducting wires are respectively connected with the positive and the negative wiring terminals of the charging interface, whereas, the other ends are respectively connected with the positive and the negative wiring terminals of the battery jar; and the first conducting wire is connected in series with a diode, the input end of the diode is connected with the positive wiring terminal of the charging interface, and the output end is connected with the positive wiring terminal of the battery jar. The charge connecting wire provided by the utility model has a simple structure, and adopts the design that the first conducting wire is connected in series with the diode, the input end of the diode is connected with the positive wiring terminal of the charging interface, and the output end is connected with the positive wiring terminal of the battery jar, so that when coins, metal wires, or other conductive metals are in contact with the positive and the negative wiring terminals due to carelessness of children, a circuit can not be formed due to the one-way conducting property of the diode, accordingly, short circuit is avoided, and the safety of the children is ensured.
Description
Technical field
The utility model relates to electric automobiles, particularly relates to a kind of charging connecting line that is used to connect electric motor car storage battery and charger.
Background technology
The connecting line of electric motor car storage battery charging at present has charging inlet and first and second lead; One end of first and second lead is connected with the positive and negative binding post of charging inlet respectively; The other end is connected with the positive and negative binding post of storage battery respectively, and charging inlet is fixed in the electric motor car, during charging; Plug on the charger is linked to each other with charging inlet, can charge storage battery.After charged, the plug of charger is extracted, this moment, the positive and negative binding post of charging inlet was in exposed state; Because child is active; Accidentally conducting metals such as coin, wire are contacted with positive and negative binding post sometimes, connect circuit and form short circuit, make child injured; Therefore the fail safe of existing charging connecting line is not high, is badly in need of improving.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, safe electric motor car storage battery charging connecting line.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of electric motor car storage battery charging connecting line; Comprise charging inlet and first and second lead, charging inlet comprises positive and negative binding post and outside insulation shell thereof, and an end of first and second lead is connected with the positive and negative binding post of charging inlet respectively; The other end is connected with the positive and negative binding post of storage battery respectively; Series diode on wherein said first lead, the input of diode links to each other with the positive binding post of charging inlet, and output links to each other with the positive binding post of storage battery.
The utility model electric motor car storage battery charging connecting line is simple in structure, is employed in the design of series diode on first lead, and the input of diode is linked to each other with the positive binding post of charging inlet; Output links to each other with the positive binding post of storage battery; Because diode has unidirectional on state characteristic, therefore when child contacts conducting metals such as coin, wire accidentally with positive and negative binding post, can't form the loop; Thereby can not be short-circuited, guarantee child's safety.
Be described further below in conjunction with the electric motor car storage battery charging connecting line of accompanying drawing the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model electric motor car storage battery charging connecting line;
Fig. 2 is the structural representation of the utility model electric motor car storage battery charging connecting line charged state.
Embodiment
As shown in Figure 1; The utility model electric motor car storage battery charging connecting line comprises charging inlet and first and second lead 1,2; Charging inlet comprises positive and negative binding post 3,4 and outside insulation shell 5 thereof; One end of first and second lead 1,2 is connected with the positive and negative binding post 3,4 of charging inlet respectively, and the other end is connected with the positive and negative binding post 7,8 of storage battery 6 respectively, series diode 9 on first lead 1; The input of diode 9 links to each other with the positive binding post 3 of charging inlet, and output links to each other with the positive binding post 7 of storage battery 6.
In the utility model electric motor car storage battery charging connecting line, charging inlet is fixed in the electric motor car, and is as shown in Figure 2, during charging, will link to each other with the positive and negative binding post 3,4 of charging inlet with the plug on the charger that power supply 10 links to each other, can charge to storage battery 6.After charged, the plug of charger is extracted, this moment, the positive and negative binding post 3,4 of charging inlet was in exposed state; When child contacts conducting metals such as coin, wire accidentally with positive and negative binding post 3,4; Because be in series with diode 9 on first lead 1, diode 9 has unidirectional on state characteristic, therefore can't form the loop; Thereby can not be short-circuited, guarantee child's safety.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection range of the utility model claims.
