Similarly AC charge port charging terminals is also to occur in pairs, may be to be multiple, and principle is same as above, still can be real Apply application.
Wherein, connecting terminal 2 is electrically connected with charging harness 3, and there are many arrangement forms of connecting terminal 2, retouches in detail below It states.
First alternative embodiment according to the present invention, as shown in Figure 1-Figure 3, connecting terminal 2 may include: the first sealing room 21 and liquid metal 22, the first sealing room 21 is fixed in shell 1, and liquid metal 22 is contained in the first sealing room 21.
Wherein, liquid metal 22 has heat superconducting and superconducts ability, and vehicle is in high-power charging process, by liquid The setting of state metal 22 makes connecting terminal 2 be resistant to high current at work, also, in terminals in the first sealing room 21 Son 2 will not generate excessive resistance heat when working.In addition, the heat that connecting terminal 2 generates during the work time, a part of meeting It is diluted by liquid metal 22, another part can be dispersed into air, can make 2 calorific value of connecting terminal so substantially as a result, Degree is reduced, and so as to efficiently solve 2 terminal burning problems of connecting terminal, and then the use and safety of vehicle can be improved Property.
Optionally, as shown in Figure 1-Figure 3, charging unit 10 is set as charging socket 65 or charging unit 10 can be Charging gun 66, that is to say, that the charging unit 10 of such setting can be adapted for charging socket 65, be readily applicable to charging gun 66.As shown in Figure 1, during Vehicular charging, after charging socket 65 is docked with charging gun 66, charging socket 65 and charging gun 66 Both ends connecting terminal 2 contacts with each other, and the purpose to Vehicular charging may be implemented in this way.
Optionally, as shown in Figure 1-Figure 3, the first sealing room 21 may include: sealing shroud 211 and sealing-plug 212, sealing shroud 211 one end is provided with hole, and hole can be set to be opened on the end of sealing shroud 211 and only by the end of part sealing shroud 211 It opens, hole is also possible to the completely open hole in 211 one end of sealing shroud, that is to say, that one end of sealing shroud 211 can be open end. Sealing shroud 211 is fixed in shell 1, and sealing-plug 212 has sealing function, and sealing-plug 212 seals the hole on sealing shroud 211, this Sample sealing-plug 212 seals hole, can prevent the liquid metal 22 in the first sealing room 21 from omitting and come out.Meanwhile sealing-plug 212 Surface it is smooth, when the connecting terminal 2 at charging socket 65 and 66 both ends of charging gun contacts, charging socket 65 and charging can be made The connecting terminal 2 at 66 both ends of rifle is preferably bonded together.
Specifically, one end periphery of sealing shroud 211 is provided with annular groove, sealing-plug 212 be set at annular groove with The hole on sealing shroud 211 is sealed, setting in this way can preferably be connected to annular groove and sealing-plug 212 together, can be with Make annular groove and sealing-plug 212 structure is even closer, so as to further prevent liquid metal 22 to flow out from hole.
Certainly, the setting form of sealing shroud 211 is not limited to this, and sealing shroud 211, which is also possible to both ends, all has hole, sealing Plug 212 is two, and two sealing-plugs 212 seal two holes of sealing shroud 211 respectively.
Optionally, sealing-plug 212 is set as conduct piece, can guarantee that electricity is oriented to charging socket 65 from charging gun 66 in this way. As a result, when charging socket 65 is docked with charging gun 66, the connecting terminal 2 of charging socket 65 and the connecting terminal 2 of charging gun 66 Between can effectively dock and transmit electric current.
Further, at least part of sealing-plug 212 protrudes into hole to seal the hole of sealing shroud 211, it is to be understood that Sealing-plug 212, which can be, partially protrudes into hole, is also possible to all protrude into hole, and setting in this way can seal hole more preferable, thus It can guarantee the safety with higher at work of charging unit 10.
Further, as shown in Figure 1-Figure 3, connecting terminal 2 is connected with charging harness 3, and sealing shroud 211 is conduct piece, fills Wirning harness 3 is connected with conduct piece, it is understood that is that charging harness 3 is connected with sealing shroud 211, also, the harness 3 that charges has Electric action can transmit electricity between sealing shroud 211 and charging harness 3, and during the charging process, electricity can pass through charging cable to vehicle 3 oriented vehicle of beam, so as to realize the work requirements constantly powered to vehicle.
After connecting terminal 2 makes change, connecting terminal 2 corresponding can also make to the connection type of charging harness 3 Change, below content will be described in more detail.
