    • To provide for uniform distribution of contact element bodies which are placed in a drum immersed in a galvanic bath and to provide contact to the metallic coating on components, the metallic coating of which is to be reinforced by galvanic deposition, the contact elements comprise tiny, especially cylindrical cores made of a material having approximately the same order of magnitude of specific gravity as the components, for example being made of a similar material, of glass, plastic, or the like, and coated with a metallic coating on the outside, essentially entirely covering the cores. The coating may be nickel or copper, and for use with tiny capacitors, lead-through elements, and the like, a preferred size of about the same length as diameter of the coated e.g. cylindrical cores is suitable, for example about 3 mm length and diameter. These elements can be made by multiple dry extrusion, with the edges rounded off before being coated.
    • 为了提供均匀分布的接触元件体,其放置在浸入电镀浴中的滚筒中并且提供与部件上的金属涂层的接触,金属涂层将被电沉积加强,接触元件包括微小的, 特别是由具有与例如由玻璃,塑料等类似的材料制成的组分大致相同的比重量级的材料制成的圆柱形芯,并且在外部涂覆有金属涂层,基本上 完全覆盖核心。 涂层可以是镍或铜,并且用于微小的电容器,引入元件等,优选尺寸与涂覆的例如直径相同的长度。 圆柱形芯是适合的,例如约3mm长度和直径。 这些元件可以通过多次干挤出制成,边缘在被涂覆之前被倒圆。
