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,.
Fig. 2 shows the structural schematic diagrams of connection male end, and as seen from Figure 2, connection male end 100 is fixed on battery pack
End, including plug fixed plate 110 and a pair of of the plug terminal 120 being arranged in plug fixed plate 110, plug terminal 120 it
Between be disposed with a pair of of signal pin 130.The outside of plug terminal 120 and signal pin 130 is equipped with the protection shell 111 of protrusion, letter
The outside of number needle 130 is equipped with gasket 131 to improve sealing waterproofness.It is respectively fixed at the both ends of plug fixed plate 110
Guide post 112, to guide to positive connection male end 100 and connect plugging together for female end 200.
Fig. 3 is referred to, plug terminal 120 includes electrode plug 121 and the sheath being fixedly sheathed on electrode plug 121
122, it is preferably bolted on electrode plug 121.Wherein electrode plug 121 is preferably sheath made of conductive good copper is standby
122 be preferably what stainless steel was prepared.The sheath 122 plays the role of: guard electrode connector, and reduction is frequently locking
During unlock, electrode contact is caused to damage, influences the locking effect of electrode contact.It is opened up on the outer peripheral surface of sheath 122
There is annular groove 1221.
Fig. 4-Fig. 6 is referred to, connection female end 200 includes being connected to the fixing shell 210 at vehicle body end and being arranged in fixation
A pair of of female terminal 220 on shell 210.In fixing shell 210 corresponding to signal pin 130 position be equipped with convex ribs 212, with
The signal pin 130 plugs together realization connection.The outside of female terminal 220 and convex ribs 212 is equipped with the protection shell 111 of protrusion.
The guide sleeve 211 for cooperating with the guide post 112 and realizing grafting guiding is additionally provided in fixing shell 210.
Female terminal 220 is preferably made of copper, and top has the slot 221 plugged together with plug terminal 120, slot
The accommodating hole 222 of multiple perforation cavity walls is offered in 221 cavity wall, is placed with a heading in each accommodating hole 222
223.The number of accommodating hole 222 is not less than 2, and is preferably uniformly disposed circumferentially in the cavity wall.
Heading 223 can be made of hard, high-intensitive material, such as metal, ceramics, and in the present embodiment, heading 223 is one
Steel ball.The diameter of heading 223 should be greater than the thickness of cavity wall, and restrained motion state is in accommodating hole 222, i.e., it can hold
It sets in hole 222 and rolls, and when heading 223 is rolled to the opening at 222 both ends of accommodating hole, partly protrude the accommodating hole
222, but cannot be detached from from accommodating hole 222 completely.This can be set smaller than heading 223 by the opening to obtain.Certainly,
In other embodiments, it can also be obtained by the way that the modes such as retaining ring, block are arranged in opening.
Connecting female end 200 further includes movable shell 230.230 sliding sleeve of movable shell is loaded on the outside of female terminal 220,
It from bottom to top successively include the first periphery 231 and slightly larger the second periphery 232 of diameter inside it；Wherein, the first circumference
It is smoothly connected between face 231 and the second periphery 232 by transition cambered surface 233, outside the first periphery 231 and female terminal 220
Circumferential surface is in contact.
Vehicle body end is equipped with mandril 240, is used to jack the movable shell 230, in the mistake that movable shell 230 is jacked
Cheng Zhong, the transition cambered surface 233 of movable shell 230 start to press the heading 223, push heading 223 towards the direction of slot 221
It rolls；When the first periphery 231 presses the heading 223, heading 223 can be pressed into the annular groove 1221, realize connection
Male end 100 and the locking for connecting female end 200.
In the present solution, the shape in 1221 section of annular groove can be arc, triangle, rectangle, trapezoidal etc., preferably arc,
The preferred arc is matched with the part of 223 protrusion accommodating hole 222 of heading；In this way, then heading 223 is with annular groove 1221
Contact area is maximum, and the effect of locking is best.
Preferably, the slot bottom of the accommodating hole 222 is an inclined-plane, and when mandril 240 is withdrawn, corresponding accommodating hole 222 is
Second periphery 232, heading 223 are driven and slided along the inclined-plane by plug terminals 120, to be detached from annular groove 1221.This
When, plug terminal 120 and female terminal 220 are in the unlocked state, can extract plug terminal 120 from slot 221.
In the present solution, if the diameter of heading 223 indicates that the thickness of 221 cavity wall of slot is indicated with s, and d > s with d, then second
The difference of the radius of periphery 232 and the first periphery 231 is at least (d-s)；In this way, when then mandril 240 is recalled, 223 energy of heading a ball
It is enough to be exited completely from annular groove 1221, and be unlikely to that plug terminal 120 is stopped to be detached from from slot 221.
Preferably, closed cyclic annular groove body 234, the ring-type are formed between the female terminal 220 and movable shell 230
Pressure spring 235 is equipped in groove body 234.After mandril 240 jacks movable shell 230, between plug terminal 120 and female terminal 220
Locking, pressure spring 235 is in pressured state at this time.When needing to unlock, the thrust for being applied to mandril 240 is removed, pressure spring 235 pushes
Movable shell 230 declines, and heading 223 is detached from from annular groove 1221, and plug terminal 120 and female terminal 220 are in unlock at this time
State.
In the present solution, the thrust being applied on mandril 240 is provided by the vehicle body end of electric car, it is installed on when by battery pack
When installation site on vehicle body, vehicle body end can automatic sensing arrive the installation of battery, and apply thrust on mandril 240, jacking work
Dynamic shell 230, realizes the fixation of battery pack.In the driving process of automobile, which stablizes constant, ensure that plug and socket
The stability of locking is conducive to the stability for improving connection, avoids causing damages to control system.
In addition, change the leakproofness of electric connector to improve the utility model, movable shell 230 and protection shell 111 it
Between, between plug terminal 120 and plug fixed plate 110, plurality of positions are equipped between female terminal 220 and fixing shell 210 etc.
Sealing ring 250.
According to description above-mentioned, it will be seen that, the technical staff in the field is it is contemplated that change electric connector for above-mentioned
It is applied to electric car, so that connection female end 200 is connected on the vehicle body of automobile, connection male end 100 is fixed in battery pack.It can
To understand, the electric car being achieved in that also has the advantages that corresponding to the utility model.
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.
