A kind of electrokinetic cell four-wire type test fixture, comprise housing, one group of contact element and one group of elastic component, described housing is provided with one group of through hole and one group of holding tank, described holding tank is provided with opening near a side of described through hole, described contact element is movably set in described through hole, described elastic component is arranged in described holding tank, and an end of described elastic component is connected to the holding tank bottom, and the other end is connected with described contact element.
Preferably, described contact element comprises contact element body, blocking part and limiting section, described blocking part is located on described contact element body and with described elastic component and is connected, and described limiting section is located at the end of described contact element body and can be bent with respect to the contact element body.
Preferably, the front end indentation of described contact element body.
Preferably, described elastic component is spring.
Preferably, the cross section of described through hole is rectangle.
Preferably, the sidewall of described housing is provided with the wedge shape fixture block.
After adopting technique scheme, the utility model is compared with existing background technology, has following advantage:
(1) can, according to voltage, the electric current index of different money batteries, adjust flexibly the quantity of contact element to adapt to testing requirement, highly versatile.
(2) simple in structure, easy to assembly, greatly reduce production cost.
(3) contact element is not yielding, reliable with battery positive and negative electrode contact stabilization.
