Embodiment
Below, be described with reference to the accompanying drawings the realization of embodiment of the invention plug and socket.
Described charging pile is generally positioned on the charging pile with socket, is connected with the respective lines or the unit of charging pile inside by cable; Described plug is generally positioned on the battery or battery controller that need utilize charging pile charging, by in cable and battery or the battery controller corresponding continuously or the unit continuous.Certainly, in actual applications, also can be arranged on the charging pile by described plug, described socket is arranged on battery or the battery controller, does not limit here.Below, so that socket is arranged on the charging pile, plug is arranged on battery or the battery controller and describes for example.
Fig. 1 is the structural representation of plug of the present invention, and as shown in Figure 1, this plug comprises: the first contact pin N1, the second contact pin L1, the 3rd contact pin PE1 and first pedestal 10; Wherein, the described first contact pin N1, the second contact pin L1 and the 3rd contact pin PE1 partial fixing are in first pedestal 10, part is positioned at the outside of first pedestal 10, described first pedestal 10 links to each other with corresponding line in the cable, and then realizes being connected with battery or battery controller (not shown) by cable.
Wherein, this plug can be used to transmit alternating current.
When the transmission alternating current, alternating current can be transmitted the most battery controller of battery charge, and then alternating current is converted to direct current by battery controller, be battery charge.At this moment, the described first contact pin N1 is used to connect ground (N) end of battery controller; The second contact pin L1 is used to connect just (L) end of battery controller; The 3rd contact pin PE1 is used for connecting protection ground.
This plug can also comprise: the 4th contact pin CP1 and the 5th contact pin CS1; Described the 4th contact pin CP1 and the 5th contact pin CS1 also partly are arranged at the inside of first pedestal 10, and part is positioned at the outside of first pedestal 10.Described the 4th contact pin CP1 and the 5th contact pin CS1 are used to transmit the inserting state information of plugs and sockets; For example, can be with the 4th contact pin CP1 in the plug and the 5th contact pin CS1 internal short-circuit, thereby after plug is inserted on the socket, the control system of charging pile can determine whether described plug is inserted, if short circuit by detecting between the 4th contact pin CP1 and the 5th contact pin CS1 whether short circuit on socket, illustrate that plug inserts on socket, if not short circuit illustrates that plug do not insert, thereby can point out to the user on socket.
In addition, this plug can also comprise: the 6th contact pin CAN1+ and the 7th contact pin CAN1-, described the 6th contact pin CAN1+ and the 7th contact pin CAN1-partial fixing are in first pedestal 10, and part is positioned at outside first pedestal 10.Described the 6th contact pin CAN1+ is connected being used in the battery and carries out the battery controller that battery identification and battery charging state detect, transmission battery authentication information and battery charging state information with the 7th contact pin CAN1-.Concrete, in the battery controller corresponding sensor can be set, so that detect the charged state of battery, in addition, can also preserve the signs such as sequence number of battery, thereby be transferred to charging pile one side by cable, the 6th contact pin CAN1+ and the 7th contact pin CAN1-,, whether battery charged so that whether charging pile one side can legal by the identity validation battery of battery; And then can also in battery charging process, obtain the charging status information of battery.
Concrete, described first contact pin~the 3rd contact pin, the 6th contact pin are identical with the cross-sectional diameter of the 7th contact pin, and the 4th contact pin is identical with the cross-sectional diameter of the 5th contact pin.The cross-sectional diameter of described first contact pin~the 3rd contact pin, the 6th contact pin and the 7th contact pin can be greater than the cross-sectional diameter of the 4th contact pin and the 5th contact pin.
Wherein, for the convenience of producing etc., above-mentioned contact pin can be evenly distributed on first pedestal 10, and for example, as shown in Figure 1, the cross section mid point of the described first contact pin N1, the second contact pin L1, the 3rd contact pin PE1 is positioned on the diameter A-A of first pedestal 10.The 6th contact pin CAN1+ is parallel with described diameter A-A with the determined straight line B-B of the cross section mid point of the 7th contact pin CAN1-, the straight line C-C that the cross section mid point of the 4th contact pin CP1 and the 5th contact pin CS1 is determined is also parallel with described diameter A-A, and straight line B-B and straight line C-C are positioned at the both sides of diameter A-A.Certainly, in actual applications, can also use other contact pin arrangement mode, not limit here.
As shown in Figure 2, be the A-A place profile of plug, the top of above-mentioned each contact pin can comprise insulation plug 11, so that each contact pin is played the insulation protection effect.
In addition, described first pedestal 10 can comprise: the pedestal 101 and the first back pedestal 102 before first; Wherein, be fixed with described contact pin in the first preceding pedestal 101, the first back pedestal 102 is fixed with the corresponding cable line connecting portion 103 that links to each other with contact pin; Described cable line connecting portion 103 is the corresponding line of stube cable respectively, so that realize that contact pin docks with the corresponding line of cable, and then realizes that contact pin connects battery or battery controller by cable.
The outside of described first pedestal 10 also is provided with hood 120, is used to protect described first pedestal 10.In addition, this hood 120 can also some be arranged at the cable outside that connects first pedestal 10, thus the part that the protection cable is connected with first pedestal 10.
In addition, can described first pedestal 10 and hood 120 be fixed together, in addition, shown in 3, can also cushion and be connected by packing ring 19 between described connecting ring 18 and hood 120, connecting ring 18 and first pedestal 10 by connecting ring 18.
In addition, as shown in Figure 2, this plug can also comprise other protectiveness parts, for example is positioned at pedestal 101 outsides before first, is used for O type circle 16 that the plug insertion socket formula cushions and protect etc., and the material of this O type circle can be silicon rubber.These protectiveness parts can independently be provided with in actual applications, repeat no more here.
