Quick Connect Kit comprises: mutually can dock the first pair of accessory 1 and second pair of accessory 2 that are connected as a single entity, be respectively equipped with the first binding post 11,21 being connected to high-tension battery 31 and high voltage electric device equipment 32 in first pair of accessory 1 and second pair of accessory 2, in first pair of accessory 1 and second pair of accessory 2, be also respectively equipped with the second binding post 12,22 being connected to control device.
Incorporated by reference to shown in Figure 2, be the external structure schematic diagram of Quick Connect Kit in the present embodiment, in the present embodiment, the first pair of accessory 1 be male end to accessory, second pair of accessory 2 is that wire harness side is to accessory.The inside of two pairs of accessories is provided with corresponding card holding structure, and can to realize mutual grafting fastening, when two pairs of accessories plug mutually, the binding post being arranged on two pairs of accessory inside can connect or disconnect, and realizes being switched on or switched off of corresponding high tension loop L1 and high-voltage interlocking loop L2.
In the present embodiment, the first binding post 11(is as shown in Figure 3) be installed in the middle part of first pair of accessory 1, it is connected with high voltage electric device equipment 32.First pair of accessory 1 is provided with at top as shown in Figure 2 and is installed in lock piece 13 in block slidably lock piece 13, second binding post 12.
Preferably, the second binding post 12 in first pair of accessory 1 is plug construction.
Further, the first binding post 21 in second pair of accessory 2 is also installed in the middle part of second pair of accessory 2, the position of its device is corresponding with the position of first pair of accessory 1 first binding post 11, can realize the reliable connection of two-terminal when first pair of accessory 1 and second pair of accessory 2 grafting, the first binding post 21 is connected with high-tension battery 31.The second pair of accessory 2 is provided with position and the suitable boss 23 of lock piece 13, the second binding post 22 in second pair of accessory 2 is installed in boss 23, the second binding post 12 can be driven when first pair of accessory 1 and second pair of accessory 2 grafting to move by slider latch 13, and can to realize between its with the second binding post 22 in boss 23 reliable is connected.
Preferably, the second binding post 22 in boss 23 is jack structure that can be suitable with the second binding post 12 plug construction in above-mentioned first pair of accessory 1.Wherein: the effect of the first binding post 11,21 is switched on or switched off high-voltage interlocking circuit system mesohigh loop L1 respectively, the effect of the second binding post 12,22 is switched on or switched off high-voltage interlocking circuit system mesohigh interlocking loop L2 respectively.
Particularly, because the first binding post 11,21 is installed in first pair of accessory 1 and second pair of accessory 2 respectively, when the first binding post 11,21 connects or disconnect, being switched on or switched off of high tension loop L1 can be realized; Because the second binding post 12,22 is installed in lock piece 13 and boss 23 respectively, when lock piece 13 is close or make the second binding post 12,22 connect away from boss 23 or disconnect, being switched on or switched off of high-voltage interlocking loop L2 can be realized.
In the present embodiment in the effect arranging the second binding post 12,22 on slidably lock piece 13 and boss 23 be: keep the sequencing that high tension loop L1 and high-voltage interlocking loop L2 is switched on or switched off, such as: during connection, high tension loop L1 first connects, and connects after the L2 of high-voltage interlocking loop; When needing to disconnect, high-voltage interlocking loop L2 first disconnects, and disconnects after high tension loop L1, and it can guarantee the time long enough that high tension loop L1 and high-voltage interlocking loop L2 disconnects, and ensures the fail safe of operation.Its concrete structure following detailed description.In addition, lock piece 13 configures two binding posts, the neglected loading of lock piece 13 can be prevented, improve the reliability of assembling further.
Further, the control device in the present embodiment comprises: the power supply 41 be connected with the second binding post 22 in second pair of accessory 2 respectively and controller 42, wherein: controller 42 connects high-tension battery 31; The second binding post 12 on first pair of accessory 1 and the second binding post 22 in second pair of accessory 2 in succession locking time, power supply 41 and controller 42 are connected.
Power supply 41 in the present embodiment adopts 12V DC power supply, at power supply 41 with under the situation of controller 42 conducting, because controller 42 connects high-tension battery 31, will control high tension loop L1 and be energized when controller 42 receives the 12V Voltage Feedback of DC power supply 41.That is, whether the effect being in the high-voltage interlocking loop L2 be turned on or off controls high tension loop L1 to be energized, and then can ensure that operator can operate under the environment of safety.
Incorporated by reference to see Fig. 1-Fig. 5, Quick Connect Kit of the present invention in the specific implementation, first, first pair of accessory 1 and the docking of the second pair of accessory 2 can be connected as a single entity, the first binding post 11,12 phase in first pair of accessory 1 and second pair of accessory 2 in succession, due to the first binding post 11, the two ends of 12 connect high-tension battery 31 and high voltage electric device equipment 32 respectively, and high tension loop L1 is in the state of connection, but now high tension loop L1 is not energized.
And then, slider latch 13 drives the second binding post 12 on first pair of accessory 1 to move, and after lock piece 13 docks completely with boss 23, first pair of accessory 1 and second pair of accessory 2 realize secondary locking.Now, the second binding post 12,22 phase in first pair of accessory 1 and second pair of accessory 2 in succession, due to the second binding post 12, the two ends of 22 connect power supply 41 and controller 42 respectively, and high-voltage interlocking loop L2 is in the state of connection, and controller 42 controls high-tension battery 31 and is energized.
