Background technology
The electric vehicle industrialization engineering has been listed in the great special scientific research project of CHINESE INDUSTRIES chemical industry journey.Tackle key problems through country " eight or five ", " 95 " " 15 " by the great special scientific research project of national electric vehicle industrialization that the Department of Science and Technology is presided over, obtained major progress; State Grid Corporation of China starts and the pilot work of expansion electric automobile public energy source safeguards system key project in seven net province companies.A large-scale vehicle electric system engineering blueprint makes first appearance.
When charging electric vehicle, to use usually a kind of be used for charger be recharged the charge connector that equipment (as electric automobile, battery system) links together.In fact this charge connector is exactly more than a kind of rated voltage DC600V, and rated current surpasses the high current connector of DC200A.As shown in Figure 1, it is made up of plug 1 and socket 2, and an end of plug 1 links to each other with charger, and the other end cooperates with socket 2; The other end of socket 2 links to each other with control circuit with the power input of battery system on being recharged equipment such as electric automobile, is storage battery or charging electric vehicle.The main effect of this connector is: safety connects and separates the dc charging power supply of high voltage, big electric current, and charge control line, CAN connection etc. is continuous.
In use, it is found that: if under the situation that does not have the charge closing machine, when DC charging voltage reaches under the non-vanishing situation of the above charging current of hectovolt, plug and unplug the plug and socket of charge connector, the direct-current arc burning serious accident that can not extinguish automatically will be produced, personal safety to vehicle safety and operating personnel causes great threat, and is abnormally dangerous.
Summary of the invention
In view of the foregoing, the purpose of this utility model provides a kind of multi-functional, high voltage that is used for but is not limited to that charging electric vehicle uses, heavy DC breaking piece.
For achieving the above object, the utility model adopts following design: a kind ofly be used for but be not limited to the breaking piece that charging electric vehicle is used, it is combined by plug and socket, it is characterized in that:
Design has two rated current can reach DC250A on described plug, and isolation voltage is the big electric current jack of 2500V; Three rated current are the jack of DC75A; Eight rated current that are mainly used in communication, transfer of data are the auxiliary jack of DC5A;
On the described socket design have two with plug on rated current be DC250A, isolation voltage is that the rated current that the jack of 2500V is complementary is the contact pin of DC250A; Three with plug 1 on rated current be that the rated current that the jack of DC75A is complementary is the contact pin of DC75A; Eight with plug on rated current be that the rated current that the auxiliary jack of DC5A is complementary is the auxiliary contact pin of DC5A.
The length of eight auxiliary contact pins on the described socket is lacked 10 millimeters than the length of other five big electric current contact pins.
The utility model has the advantages that: even misoperation under the situation that charging device does not cut out, also can be at big electric current contact pin with before big electric current jack separates, automatic charge closing device, the charging current and the voltage of charging device output are reduced to zero, thereby guarantee plug connector under any state, can not produce direct-current arc, guarantee the safety of plug connector.

Embodiment
As shown in Figure 2, the disclosed a kind of charging breaking piece that is used for but is not limited to used for electric vehicle of the utility model is combined by plug 1 and socket 2.
Shown in Fig. 3-A, Fig. 3-B, two rated current are arranged is DC250A in design on plug 1, and isolation voltage is the big electric current pin type jack 3 of 2500V, is mainly used in but is not limited to the dc voltage electrode and the negative pole of charging device output coupled.
The design jack 4 that two rated current are arranged is DC75A also on plug 1 is mainly used in but is not limited to charging device and is recharged between the equipment (as electric automobile) low-voltage direct and controls the coupled of power supply.
The design jack 5 that a rated current is arranged is DC75A also on plug 1 is mainly used in but is not limited to charging device and is recharged the coupled of equipotential (ground connection) point between the equipment (as electric automobile).
The design auxiliary jack 6 that eight rated current are arranged is DC5A also on plug 1 is mainly used in but is not limited to charging device and is recharged communication between the equipment, transfer of data (CAN, RS-485 or analog signal, switching signal).
Shown in Fig. 4-A, Fig. 4-B, Fig. 4-C, on the socket 2 design have two with plug 1 on rated current be DC250A, isolation voltage is that the rated current that the jack 3 of 2500V is complementary is the contact pin 7 of DC250A.
On the socket 2 also design have two with plug 1 on rated current be that the rated current that the jack 4 of DC75A is complementary is the contact pin 8 of DC75A.
On the socket 2 also design have one with plug 1 on rated current be that the rated current that the jack 5 of DC75A is complementary is the contact pin 9 of DC75A.
On the socket 2 also design have eight with plug 1 on rated current be that the rated current that the auxiliary jack 6 of DC5A is complementary is the auxiliary contact pin 10 of DC5A.
As shown in Figure 1, in charging process, plug 1 or socket 2 are linked to each other with charging device by cable, socket 2 or plug 1 are linked to each other with the equipment of being recharged by cable to get final product.
For fear of in charging process, because of the direct-current arc burning serious accident that does not have the charge closing machine to produce with regard to the plug and socket that plugs and unplugs connector, as shown in Figure 5, the utility model becomes the Design of length of eight auxiliary contact pins 10 on the connector body 2 than the length of five big electric current contact pins 7,8,9 to lack 10 millimeters.Assist the interior startup of contact pin 10 and charging device to be connected with stop control apparatus.Only when contact pin 10 reliably was connected with jack 6, charger ability normal boot-strap and output current charged.In charging process, when contact pin 10 separates with jack 6, charging device will cut out output current in 1 millisecond, and charge closing device automatically.
Under normal charging condition during the plug and socket of plug-in connector, suppose plug 1 and socket 2 speed lock out operation with 1 meter of per second, because the length of eight auxiliary contact pins 10 on the connector body 2 is than 10 millimeters of five big electric current contact pin 7,8,9 weak points, so the auxiliary contact pin 10 on the socket 2 shifts to an earlier date about 10 millisecond than other big electric current contact pin 7,8,9 with jack 3,4,5 with jack 6 to be separated.At large current charge contact pin 7,8,9 with before jack 3,4,5 separates, as mentioned above, charger stops charging, automatic charge closing device, guarantee that the contact pin on the socket 2 separates under zero current, no-voltage with jack on the plug 1, thereby guarantee the fail safe that connector is operated under any condition.
The utility model has the advantages that: even misoperation under the situation that charging device does not cut out, also can be at big electric current contact pin 7,8,9 with before big electric current jack 3,4,5 separates, automatic charge closing device, the charging current and the voltage of charging device output are reduced to zero, thereby guarantee plug connector under any state, can not produce direct-current arc, guarantee the safety of plug connector.
The above is concrete exemplifying embodiment of the present utility model and the know-why used, and is any based on the equivalent transformation on the technical solutions of the utility model basis, all belongs within the utility model protection range.
