本实用新型专利技术涉及一种动力电池极耳焊接结构,包括铜极耳、铝极耳和铜排,铜极耳和铝极耳顶面前端插接形成单层极耳顶面,该单层极耳顶面底部焊接铜排。铜极耳和铝极耳以插槽、插头方式进行插接;所述铜极耳顶面前端形成交错设置的第一插头和第一插槽;所述铝极耳顶面前端形成与所述第一插头适配的第二插槽、以及与所述第一插槽适配的第二插头。本实用新型专利技术通过改变极耳的形状,使得铜极耳和铝极耳可以对插,同时与铜排接触,避免了Al‑Cu‑Cu三层焊接,从而保证焊接的可靠性。

Welding structure of electric battery pole ear

The utility model relates to a kind of electric battery pole ear welding structure, which includes copper pole ear, aluminum pole ear and copper row, copper pole ear and aluminum pole top face to be inserted in front end to form single pole ear top surface, and the bottom of the single layer pole face is welded with copper row. The copper pole ear and the aluminum pole are plugged in the way of slots and plugs; the front end of the copper polar ear top forms a staggered first plug and a first slot; the front end of the aluminum polar ear top forms a second slot adapted to the first plug, and a second plug suitable for the first slot. By changing the shape of the polar ear, the copper pole and the aluminum pole can be inserted and contacted with the copper row to avoid the welding of the Al Cu Cu three layer, thus ensuring the reliability of the welding.
