What Fig. 1 showed a kind of embodiment of the utility model changes structural schematic diagram of the electric connector under plugging state.
From figure 1 it appears that it includes connection male end 100 and connection female end 200 that this, which changes electric connector,.
The connection male end 100 is fixed on battery pack end, and Fig. 2 is the structural schematic diagram for connecting male end 100.It can be with from figure Find out, connection male end 100 includes plug fixed plate 110, and the plug protective shell of hollow columnar is convexly equipped in plug fixed plate 110 130, the floating of plug terminal 120 is set in plug protective shell 130.
Specifically, referring to Figure 1-2, the bottom end of plug terminal 120 is formed with cone shaped pilot 121, and plug terminal 120 On be set with a deformed spring 140, the shape of abnormity elasticity be it is intermediate it is thin, both ends are thick;Plug protective shell 130 is opened close to top It is formed with retaining ring 131 on internal perisporium at mouthful, is fixed with block 150 on the outer peripheral surface of plug terminal 120, on the block 150 It is formed with cyclic annular limiting slot 151, the top of deformed spring 140 is limited by the retaining ring 131, and bottom end passes through the limiting slot 151 limits, and the deformed spring is in compressive state.
To improve sealing performance, funnel-form sealing ring 160 is additionally provided in plug protective shell 130, the funnel-form sealing ring In on the outer peripheral surface of plug terminal 120, big end opening is fixed on slotting 160 small end opening palette by tail end pressing plate 132 The top open part of head protection shell 130.Preferably, tail end pressing plate 132 is snapped connection in the top opening of plug protective shell 130 Place, it is fixed by fixed retaining ring 133 between tail end pressing plate 132 and plug terminal 120.
130 lower surface of plug protective shell is equipped with a pair of symmetrical guidance pin 111, is used to assist guidance connection male end 100 and connection female end 200 plug together.Certainly, in alternative embodiments, the quantity for guiding pin 111 includes but is not limited to one It is right.
Referring to Figure 1 with 3, connection female end 200 includes socket fixing board 210 and is set to inserting on socket fixing board 210 Seat terminal 220, female terminal 220 can cooperate with the plug terminal 120 to be plugged together, and the outside of female terminal 220 is equipped with columnar Socket protection casing 230, corresponding position is equipped with the jack 211 cooperated with the guidance pin 111 on socket fixing board 210.
Preferably, the top open part of socket protection casing 230 is equipped with inclined-plane 231, to guide plug terminal 120 and socket end Son 220 plugs together.The outer diameter of socket protection casing 230 is preferably less than the internal diameter of plug protective shell 130, in this way, plug when then plugging together The cover completely of protective shell 130 closes socket protection casing 230.To improve the leakproofness connected, preferably in the periphery of socket protection casing 230 Face is equipped with gasket 240, protected in plug protective shell 130 and socket when plug terminal 120 and female terminal 220 plug together It is formed and is tightly connected between protective case 230.
Preferably, it is equipped with screw thread on plug protective shell 130 and socket protection casing 230, face is fixed on by nut 170 On plate.
Plug terminal 120 has the principle of float function as follows:
In normal state, plug terminal 120 is in coaxial state with plug protective shell 130;When plug terminal 120 by To the effect of external force, there is the offset on horizontal direction and/or vertical direction, deformed spring 140 is pressurized at this time, and to plug end Son 120 generates the reaction force of opposite direction;After the external force suffered by the plug terminal 120 disappears, which will push plug Terminal 120, which returns back to, initially to be set, and continues to keep coaxial state with plug protective shell 130.
The present embodiment changes electric connector when plugging together, when not precisely aligning, the tapered guide of 120 bottom end of plug terminal Portion 121 can press on the opening of socket protection casing 230, and cone shaped pilot 121 is by reversed active force, so that plug terminal 120 shift in the horizontal and vertical directions, wherein offset in horizontal direction so that plug terminal 120 axis The axis of female terminal 220 is moved closer to, i.e. plug terminal 120 and female terminal 220 is gradually aligned, until final completely right Standard, realization smoothly plug together.After removing external force, plug protective shell 130 is returned under the action of deformed spring 140 and plug terminal 120 coaxial states.
By being analyzed above it is found that the utility model changes electric connector during charging, without alignment plug terminal 120 completely With female terminal 220, it can be realized and smoothly plug together, reduce the time for changing electricity, reduce the difficulty for changing electricity.
It can also be understood by the description above in conjunction with each figure, the field technical staff by above-mentioned it is contemplated that change Electric connector is applied to electric car, so that connection female end 200 is connected to the vehicle body of electric car, and connects the connection of male end 100 Onto battery pack.It will be seen that the electric car being achieved in that also have with the utility model to change electric connector corresponding excellent Point.
Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
