Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in more detail.

Detailed description of the invention

As it is shown in figure 1, be each provided with two panels interval to arrange conductive plate 2 at the both ends of the gripper shoe 1 of battery formation clamp, chemical conversion Time, the two panels conductive plate being positioned at same one end contacts with the positive and negative lug of dynamic lithium battery respectively.With reference to Fig. 2 and Fig. 3, Fig. 2 and Fig. 3 is the structural representation of the present embodiment conductive plate.Conductive plate 2 includes conductive plate body 2-1, insulation spacer 2-2, current conduction Copper Foil 2-3, voltage conductive Copper Foil 2-4, terminal base 2-5, insulating spacer 2-6 and elastic component 2-7.Insulation spacer 2-2 and conductive plate Body 2-1 bottom surface fits tightly, and to realize the insulation of conductive plate body 2-1 and gripper shoe, and plays the effect of padded conductive plate. Current conduction Copper Foil 2-3 and voltage conductive Copper Foil 2-4 is arranged at intervals on conductive plate body 2-1, current conduction Copper Foil 2-3 and electricity Pressure copper-foil conducting electricity 2-4 and the terminal base 2-5 being arranged at conductive plate body 2-1 end electrically connects, thus with the power supply of formation device It is connected.When lithium battery is positioned on cell support plate, current conduction Copper Foil 2-3 and voltage conductive Copper Foil 2-4 and lithium battery Lug contacts.

For the ease of describing, side adjacent for two panels conductive plate being defined as inner side, the side relative with this sides adjacent is then For outside, insulating spacer 2-6 is defined as first end 2-6a near one end of dynamic lithium battery, away from the one of dynamic lithium battery End is defined as the second end 2-6b.Insulating spacer 2-6 is set in the inner side of conductive plate, the insulating spacer 2-6 of the present embodiment and electricity Pressure copper-foil conducting electricity 2-4 is disposed adjacent, and insulating spacer 2-6 is connected with conductive plate body 2-1 by elastic component 2-7.The present embodiment Insulating spacer 2-6 is arranged in the groove of conductive plate body.The first end 2-6a of elastic component 2-7 and insulating spacer 2-6 is connected, In the case of not by external force, insulating spacer 2-6 its second end 2-6b under the elastic force effect of elastic component 2-7 is lifted, and makes Form an angle less than 90 degree between insulating spacer bottom surface and conductive plate body surface, i.e. there is no the situation of other external force Under, the second end 2-6b of insulating spacer 2-6 is lifted by elastic component 2-7 so that it is form one higher than conductive plate body surface (electricity Gripper shoe surface, pond) stop inclined-plane.The elastic component 2-7 of the present embodiment uses torsion spring, torsion spring be arranged at insulating spacer 2-6 it After, but elastic component can also be arranged at below insulating spacer, and the first end of such as insulating spacer passes through rotating shaft and conductive plate Body is connected, and torsion spring or the elastic component such as spring or gum elastic is arranged in groove, does not has other External Force Acting in insulation stop Time on block, elastic component can be by insulating spacer jack-up.

The structure of another conductive plate of the present embodiment is substantially the same with the structure of aforesaid conductive plate, and different places is only that This another sheet conductive plate is not provided with insulating spacer and elastic component but it also may insulating spacer is all set at two panels conductive plate And elastic component.Additionally, insulating spacer can also be disposed adjacent with current conduction Copper Foil.By arranging insulating spacer on conductive plate And elastic component, it is possible to prevent battery sliding transfer to cause positive and negative lug to contact same conductive plate simultaneously and be short-circuited.

During chemical conversion, dynamic lithium battery is positioned on cell support plate 1, and makes adjacent cell gripper shoe clamp, adjacent During cell support board clamping, can be by the insulation stop on cell support plate conductive plate below at upper cell support plate Press under block 2-6 so that it is overcome the elastic force of elastic component 2-7 to be flat on conductive plate body 2-1, thus the positive and negative lug of lithium battery It is fully contacted with the current conduction Copper Foil on two panels conductive plate and voltage conductive Copper Foil respectively, does not affect charging；When chemical conversion is complete When taking out battery, owing to losing pressure, insulating spacer 2-6 is lifted up under the elastic force effect of elastic component 2-7, protrudes from and leads Electroplax body 2-1 surface, can play the effect stoping its displacement, thus prevent in the process taking out battery dynamic lithium battery In, battery sliding transfer causes positive and negative lug to contact same conductive plate simultaneously and be short-circuited.

And, as a preferred embodiment of the present utility model, the centerline parallel of insulating spacer is in the center of lug Line, and the first end of insulating spacer is connected with conductive plate body, the second end can be lifted under the elastic force effect of elastic component, The top margin of battery will not be damaged when insulating spacer is pressed down by pressure, battery pole ear also will not be occurred to slip over from gap, insulating spacer bottom surface Cause the situation of short circuit.

Above example is only in order to illustrate that the technical solution of the utility model is not intended to limit, although with reference to above-mentioned enforcement This utility model has been described in detail by example, it should be understood by a person of ordinary skill in the art that still can be to this reality Modify or equivalent by novel detailed description of the invention, and repair without departing from any of this utility model spirit and scope Changing or equivalent, it all should be contained among right of the present utility model.
