The utility model content
At above deficiency, the utility model provides a kind of universal four-wire method poly-lithium battery anchor clamps that are applicable to the poly-lithium battery of different size size, it comprises positive and negative two clips, each described clip comprises train wheel bridge and lower plate, and the spring that described train wheel bridge and lower plate are installed, each described train wheel bridge or each described lower plate are provided with separate voltage terminal and current terminal, when each described clip clamping battery pole ear, described voltage terminal and current terminal be the separate battery pole ear that contacts respectively.
The voltage terminal of described same clip and current terminal are fixed on the dop position of its lower plate, are provided with insulating trip between the voltage terminal of described same clip and the current terminal.
The dop position of described lower plate is formed with groove downwards, form the bending section consistent in the middle of the described voltage terminal with described groove shapes, between the voltage terminal on groove right side and current terminal, be provided with insulating trip, and the current terminal right-hand member is suspended on the groove.
Described positive and negative two clips can adopt integral type, also can adopt split type.
Described voltage terminal and current terminal are copper sheet.
Relative prior art, the utlity model has following advantage: 1) current terminal and voltage terminal are isolated fully.Between current terminal and the voltage terminal insulating trip is installed, when clamping battery pole ear, the battery pole ear front and back ends contacts with voltage terminal with current terminal respectively, directly do not contact between current terminal and the voltage terminal, guaranteeing the reliable while of Battery holder, guarantee that current terminal and voltage terminal isolate fully, realize that real four-wire method measures, the test data that guarantees battery accurately and reliably; 2) can realize the clamping of various different size dimension lugs, satisfy the test request of the poly-lithium battery of different size.The novel positive and negative clamp body of this use can be made of one formula, also can make split typely, can guarantee the measuring accuracy of small size battery, also can satisfy the test request of large scale battery.
