Preferably, described strip copper sheet is two, laterally arranges, and the spacing of two copper sheets is more than or equal to 2.0cm.
Described end limiting plate is provided with horizontal slotted hole and vertical slotted hole, and the end limiting plate is connected with base through setting nut, and laterally slotted hole has setting nut to pass respectively with vertical slotted hole.
The vertical range of the last end distance end limiting plate of said strip copper sheet is more than or equal to 5mm.
The length of described end limiting plate is smaller or equal to the width of base end face, and width is more than or equal to the thickness of base.
Described side limiting plate is provided with horizontal slotted hole, and the side limiting plate is connected with base through setting nut, and setting nut passes the slotted hole on the side limiting plate.
Preferably, the horizontal slotted hole on the side limiting plate is the 1-2 bar.
The beneficial effect of the utility model is:
The lithium ion battery internal resistance and the voltage detecting clamp structure of the utility model are simple; The lug position that adapts to different-thickness electricity core through the front and back position of adjustment end limiting plate; About adjustment end limiting plate, and cooperate adjustment side limiting plate about distance adapt to the battery of different in width.The utility model highly versatile is applicable to the detection of different-thickness and different in width battery, adopts this anchor clamps, and is convenient, fast, time saving and energy saving, improved the accuracy and the production efficiency of battery detecting.
