The invention relates to a method for improving the transition resistance in an electrical connection, in particular a pressure connection, between two contact elements. With repeated mechanical or thermal loads, such connections, in particular connections having a small cross-section or comprising soft material, have a transition resistance which increases over time. According to the invention, the transition resistance is improved by there being applied to at least one contact face of a contact element a chemically reducing substance which activates the contact face and consequently increases the conductivity and the cold welding density.

The invention relates to an electrical contact element, an electrical contact arrangement and methods for manufacturing an electrical contact element and for reducing oxidization of a contact section of an electrical contact element. In order to avoid that the durability of the contact element and therefore of the contact arrangement is negatively influenced by growing oxide layers on contact surfaces, the contact element is provided with a cover layer with a chemical reducing agent that can be activated by frictional forces.

The invention relates to an electrical contact coating for an electrically conductive substrate, preferably a substrate made of copper, a copper-based alloy or a copper-plated substrate in particular for a high-temperature application in an electric or hybrid motor vehicle, with a layered arrangement which can be applied to the substrate and which has two layers, the one layer comprising a transition metal and the other layer a noble metal, with an intermediate layer being provided between the two layers of the layered arrangement, which intermediate layer comprises copper, and one of the two layers being an outer layer. Further, the invention relates to an electrical or electromechanical contact element for a high-temperature application, to an electrical, electronic and/or electro-optical connector, and to the use of copper or a layer comprising copper for a coating, in particular an electrical contact coating, preferably for high-temperature applications.

The invention relates to a method for producing at least one functional region (1) on an electrical contact element (30) such as, for example, a switching contact or a plug type contact. The at least one functional region (1), for example, a contact location or a connection region for crimping or soldering connections is limited to a partial area of the contact element. In order to prevent the high environmental burden which is disadvantageous in wet-chemical methods and to overcome the restriction to a very small number of materials caused in hot dip methods in physical technical terms, and to substantially improve the spatial possibility for selection and structuring which is insufficient in both techniques, there is provision according to the invention for at least one material coating (4) to be applied mechanically in a highly selective manner to the contact element in the functional region (1) and subsequently highly energetic thermal radiation (9) such as, for example, a particle beam in the form of an ion and/or electron beam, to be directed onto the at least one material coating (4). The material coating (4) can contain new materials or material combinations which cannot be provided by previous methods. The invention further relates to a device for producing such a functional region and a contact element having such a functional region (1), the contact element (30) being produced in accordance with the above method.

An electrical terminal is provided for terminating a wire. The electrical terminal includes an electrical contact and a crimp barrel extending from the electrical contact. The crimp barrel is configured to be crimped around an end of the wire. The crimp barrel includes a base and opposing side walls that extend from the base. The base and the side walls define an opening of the crimp barrel that is configured to receive the end of the wire therein. The side walls extend outwardly from the base to ends. The side walls include base segments that extend from the base and end segments that extend from the base segments and include the ends. A sealing wing extends from the end of at least one of the side walls. The side walls are configured to be folded over when crimped over the end of the wire such that a gap is defined between the end segment and the base segment of at least one of the side walls. The sealing wing is configured to extend within the gap between the end segment and the base segment of the corresponding side wall when the side walls are crimped over the end of the wire.

The invention relates to a coating (7) made up of a metal layer (8), in which a lubricant (1) which can be released by wear is embedded. In order to provide a wear-resistant coating (7) which is simply structured and economical to produce, the invention provides for the lubricant (1) to consist of an at least singly branched organic compound (2). The present invention further relates to a self-lubricating component (11) with a coating (7) according to the invention applied at least in certain portions, to a method for producing a coating (7), and also to a coating electrolyte (10) comprising at least one type of metal ions and at least one lubricant (1) consisting of an at least singly branched organic compound (2).
