A rotatable coupling for audio cables is shown having a stator and a rotor divining an electrical rotary interface (301) for providing continuous connection between audio cables. A protective stator housing (304) retains the stator and a protective rotor housing (305) retains the rotor. A rolling-element bearing (306) with an inner race and an outer race allows the protective housings to axially rotate.

A system for implementing an electrical rotary joint in a large-diameter system using relatively small-diameter capsule slip rings is described herein. The system includes a system rotor that rotates about a system axis of rotation, and a system stator that is stationary with respect to the system rotor. The system also includes at least one conductive contact channel disposed on one of the system rotor and the system stator. The system further includes at least one capsule slip ring (CSR) coupled to the other of the system rotor and the system stator. The at least one CSR has a conductive annular element coupled thereto, the conductive annular element in mechanical contact with the at least one conductive contact channel such that the at least one CSR forms an electrical rotary joint between the system rotor and the system stator.

The present invention relates to a connecting element for electrical and mechanical connection of electronics modules. The connecting element includes a base part having a receptacle area that serves to hold an electronics module, wherein the receptacle area has first electrical contact points for the electrical connection of the connecting element to electrical contact points of the electronics module. The base part includes a first end region having a first recessed section on the top side and has a second end region having a second recessed section on the bottom side. Second electrical contact points for connecting to further connecting elements are disposed on the top side of the first recessed section and on the bottom side of the second recessed section. The recessed sections are designed such that the end regions of connecting elements that are located next to each other can be positioned opposite one another in such a way that the top sides of the connecting elements are located on a plane and the bottom sides of the connecting elements are located on another plane. The second electrical contact points are disposed in such a way that the connecting elements can be positioned at different angles (a) with respect to one another. The invention also relates to an electronic module arrangement having at least one connecting element and an electronics module disposed in the receptacle area of the connecting element.

The invention relates to a power lead for a swimming pool cleaning robot. Said power lead comprises a rotary connector and a buoyancy means supporting said rotary connector. An upper part of said buoyancy means is a cap shaped to slide under a swimming pool cover, under the effect of a traction exerted by the swimming pool cleaning robot on the buoyancy means through the power lead.

A rotating power connection for connecting an electrical supply power cable to an electric welding torch body is provided. An example rotating power connector for an electric welding torch includes a housing, a socket arranged within the housing at a first end of the housing and configured to receive a welding torch neck, a connector extending from a second end of the housing and rotatably coupled to the socket, the connector configured to be secured to a welding cable, and one or more electrical contacts arranged within the housing and positioned between the socket and the connector, the one or more electrical contacts providing an electrical connection between the socket and the connector during rotation of the connector with respect to the socket.

The current invention relates to a pivot linkage device comprising at least one rolling bearing comprising at least one inner cage, one outer cage and a plurality of rolling elements denoted as the bearing components, the device further comprising means for protection against high voltage transients, wherein said protection means are exclusively formed by said bearing components, said bearing components being loaded by loading means arranged in such a manner that a direct electrical connection exists between these components. The current invention also relates to a method for protecting a bearing against high voltage transients by applying a preloading to the bearing's components.
