    摘要： A connector is disclosed, including a first insulator and a second insulator disposed along a first direction, and a plurality of conductive pieces spaced apart between the first insulator and the second insulator. Each conductive piece includes a first connecting portion and a second connecting portion. Both the first connecting portion and the second connecting portion are configured to be connected to other conductive pieces. The second connecting portions of the plurality of conductive pieces are spaced apart along a second direction. In the connector of this application, one conductive piece is connected to other conductive pieces by the first connecting portion and the second connecting portion, thereby avoiding the need of a current collecting plate, a sampling terminal, and a voltage sensing harness, and reducing the number of materials that need to be used. This application further provides a battery pack that employs the connector, and an electrical device that employs the battery pack

    摘要： A battery cell including a first electrode plate and a second electrode plate alternately stacked, where a separator is disposed between the first electrode plate and the second electrode plate. The first electrode plate includes a first current collector and a first active substance layer disposed on a surface of the first current collector. The second electrode plate includes a second current collector and a second active substance layer disposed on a surface of the second current collector. The first electrode plate further includes a first recess formed by absence of the first active substance layer and a first tab disposed in the first recess. The second electrode plate includes a second recess formed by absence of the second active substance layer. In a thickness direction of the battery cell, the first recess and the second recess are arranged opposite to each other. A first insulation layer is disposed on a surface of the first tab, and the second recess is provided with a first insulation holding member, contributing to higher structural flatness and safety of the battery cell.
