摘要： A battery lid includes an aluminum lid member, a first terminal member made of aluminum and a second terminal member made of copper, each extending to both a front side and a back side, and resin members fixing the terminal members to the lid member. Of the second terminal member, an opposite surface that faces a wall surface between the front side and the back side of the lid member via the resin member is formed with asperities, in which the resin member bites to form a minute anchor structure. The resin member is made of a base resin mixed with fillers and prepared so that its linear expansion coefficient in a range of 80% to 120% of a linear expansion coefficient of the aluminum.

摘要： A method for producing a power storage device includes an insert-molding step of making a resin member by insert-molding with respect to a terminal member inserted in an insertion hole of a lid. In this insert-molding step, the insertion hole of the lid is placed in front of a gate, and a molten resin is injected through the gate to flow in an opposite gate-side space in a cavity through the insertion hole, allowing the molten resin to spread over the entire cavity, to form the resin member.

摘要： An electrical connector assembly disposed within an opening of an electrical device case surrounded by a sealing wall extending from an internal surface of the electrical device case may include a connector header configured to be disposed outside of the electrical device case. The assembly may include a potting material seal formed of a resilient material defining a conductor passage configured to receive and engage the electrical conductor and an outer edge configured to engage the sealing wall, thereby inhibiting a liquid potting material introduced into the electrical device case from intruding into the connector header. The assembly may include a seal retainer having an opening in which the electrical conductor is disposed and configured to retain the potting material seal within the sealing wall.

摘要： A method produces a cover assembly for a cell housing of a prismatic battery cell. In the method, a cell terminal consisting of three portions is arranged on a cover plate in such a way that one portion is arranged in a through-opening of the cover plate, another portion and the cover plate overlap to form a first interspace, and a further portion and the cover plate overlap to form a second interspace. A sealing element is provided in one of the interspaces and is preloaded by compressing the interspace. The cell terminal is connected to the cover plate by introducing a plastic into the interspace without the sealing element.
