摘要： The present disclosure relates to a coupling device for coupling two or more tab electric terminals of distinct battery cells. A pair of U-shaped jaws retains the terminals therebetween with the electrical contact surfaces facing each other. A clamping element is configured to clamp the jaws towards each other in the first direction. During the clamping, an inclined wedge surface converts the pressure in the first direction to a pressure on the terminals in a second direction, so as to establish a reliable electrical contact between the terminals, direct or with the interposition of a spacing block. Wedge surfaces can be provided laterally, for example in the arms of the jaws, or between distinct bodies forming a spacing block between the terminals.
