摘要:
Electrical feedthroughs are presented that are integrated within a wall of a battery housing. In some embodiments, an electrical feedthrough includes a battery housing defining an opening. The electrical feedthrough also includes a collar disposed around the opening and forming a single body with the wall. The electrical feedthrough also includes an electrically-conductive terminal disposed through the collar. The electrical feedthrough additionally includes an electrically-insulating material disposed between the collar and the electrically-conductive terminal and forming a seal therebetween. In some embodiments, the wall has a thickness equal to or less than 1 mm. In some embodiments, the collar protrudes into the battery housing. In other embodiments, the collar protrudes out of the battery housing. In some embodiments, a cross-sectional area of the electrically-conductive terminal is at least 40% of an area bounded by an outer perimeter of the collar. Batteries incorporating the electrical feedthroughs are also presented.

摘要:
A battery bushing for a rechargeable battery has a mounting section and a contacting section. There is a torque ring, between the mounting section and the contacting section. The torque ring or the outer surface itself can be endowed with several indentations. The mounting section is for holding the battery bushing within a battery cover, into which it preferably is injection molded. The battery bushing is a hollow body, which has an outer wall and an inner wall. At the contacting section, the outer wall is conically shaped. At the mounting section, the outer wall has at least one circumferential projection forming a labyrinth. The inner wall comprises at least two sections. An upper section is approximately surrounded by the contacting section, and preferably has a conical shape. A lower section is approximately surrounded by the mounting section. The lower section preferably has in a lateral sectional view a concave shape. Between the upper section and the lower section, there may be an edge or a step.
