Abstract: An electrical contact element formed of sheet metal having a first region and a second region. Each one of the first and second regions is coated with a coating including a first layer containing a first material having a lower standard electrode potential than the sheet metal material. The coating includes a second layer in the first region which is absent in the second region. The second layer is arranged underneath the first layer and contains a second material that has a lower standard electrode potential than the first material.

Abstract: An electrical contact element and a method of manufacturing an electrical contact element having a connecting segment which is formed of a copper sheet and comprising a coating overlaying the copper sheet having at least two layers. A first layer contains at least 60% by weight of tin. A second layer is disposed between the first layer and the copper sheet. The second layer contains a copper-containing alloy. The copper-containing alloy contains 40 to 80% by weight of copper and 20 to 60% by weight of zinc. The combined percentage by weight of copper and zinc in the second layer is at least 90%. A third layer containing tin may be disposed between the second layer and the copper sheet. A fourth layer containing zinc may be disposed on a side of the first layer opposite the second layer.

Abstract: The invention relates to a current conductor, in particular for motor vehicles, to which at least one electrically conductive connector element can be fastened to make an electrical contact, with the current conductor having a recess which includes a wall section which is pierced by at least one plug opening for the connector element.

Abstract: An optical receptacle with low transmission loss, which is connectable with an optical plug, is provided. The optical receptacle includes a photoelectric conversion module having the capability of making photoelectric conversion between light signals and electrical signals, and a module housing. The photoelectric conversion module is a molded interconnect device (MID), which is provided with a module body having a post, an optical device mounted on the post, and an electrical circuit mounted on the module body. The module housing has a tubular projection, into which an end of the optical fiber supported by the optical plug can be inserted. When the optical plug is connected with an optical receptacle, the end of the optical fiber is positioned in the tubular projection so as to be in a closely opposing relation to the optical device mounted on the post.
